Bitcoin Estate Planning Checklist 2026: The 62-Item Master Guide

Why a Bitcoin Estate Planning Checklist Is Different

Every estate planning attorney will tell you to write a will, name an executor, and update your beneficiary designations. That advice is correct — but for Bitcoin holders, it is profoundly incomplete. Bitcoin has failure modes that no other asset class has ever had. Understanding those failure modes is why this checklist exists, and why it has 62 items instead of five.

Traditional estate planning assumes institutional backstops. When someone dies with a bank account, the bank holds the money and processes the estate claim. When they die with a brokerage account, the custodian holds the securities and processes the transfer on death. When they die with real estate, the title company and court system sort out the deed. In each case, a failure in documentation is recoverable. The court can compel disclosure. The bank can be petitioned. The title can be searched.

Bitcoin has no institutional backstop. The coins exist on a decentralized, permission-less ledger. No company controls them. No court can order them released. No government can compel access. The only thing that moves Bitcoin is a valid cryptographic signature — and a valid cryptographic signature requires the private key. If your heirs do not have the private key, or cannot reconstruct it from a properly documented seed phrase, the Bitcoin stays where it is. Forever. Lost. Permanently inaccessible. And given Bitcoin's trajectory, that could mean leaving an enormous and growing amount of wealth in a cryptographic black hole that no one can retrieve.

This creates a category of estate planning mistakes that simply does not exist for other assets:

• A will that names Bitcoin beneficiaries but includes no key access instructions is legally valid and operationally useless.
• A trust that holds Bitcoin but whose trustee does not know how to access the wallet is a perfectly structured vessel for permanently inaccessible property.
• A seed phrase written on paper and stored in a safe deposit box may be legally documented and physically inaccessible at the moment it matters most — because banks can freeze access to safe deposit boxes during probate.
• A multisig setup with all three keys backed up but no descriptor file backed up is, in many configurations, unrecoverable even with all three keys present — because the wallet coordinator cannot reconstruct the script without the descriptor.
• A passphrase (sometimes called the 25th word) stored in the same place as the seed phrase provides no additional security. A passphrase stored in a different place with no documentation is a one-way trap that no one — not your heirs, not your attorney, not a Bitcoin recovery specialist — can escape.

These are not edge cases. They are the most common ways Bitcoin inheritance fails. The families who avoid them are the ones who treat the Bitcoin estate planning checklist as a living practice, not a one-time event.

This checklist is organized into seven phases that reflect how Bitcoin estate planning actually works in practice — from initial inventory through annual maintenance. Each item has a brief explanation of why it matters, not just what to do. Complete the phases in order. Review them annually. Update immediately whenever anything changes about your custody setup.

You cannot plan what you have not documented. Phase 1 is about creating a complete, accurate, and securely stored record of every Bitcoin holding in your estate. This document becomes the foundation for everything else on this checklist.

• ☐
  1.1 — List all Bitcoin storage locations

  Create a master list of every place you hold Bitcoin: hardware wallets (each device separately), software wallets, exchange accounts, paper wallets, multisig arrangements, and any collaborative or institutional custody. Include the name or label you use for each, the type of custody, and the approximate purpose (long-term cold storage, active trading stack, liquidity reserve, etc.). Why it matters: Your executor cannot locate what is not documented. Bitcoin held in a forgotten wallet, an old exchange account, or a hardware device stored in a drawer is Bitcoin at serious risk of being permanently lost. Many families discover they have more Bitcoin in more places than they realized — and several of those places lack any recovery documentation. Completing this inventory is the first step to ensuring no Bitcoin is left behind.

• ☐
  1.2 — Document approximate BTC balance per location

  Record a rough balance for each storage location — enough that your executor knows which wallet holds significant funds and which holds dust. Do not record exact balances in any document that might be seen by multiple people. Approximate ranges (e.g., "a significant portion of total holdings") are safer. Why it matters: If your executor does not know which storage location is most important, they may spend weeks attempting to access a nearly-empty wallet while the primary cold storage device — holding 95% of your Bitcoin — sits untouched in a drawer. Triage requires approximate balance information. The goal is proportionality, not precision. Never include exact public addresses in a general estate document — that alone reveals your full balance to anyone who finds the document.

• ☐
  1.3 — Record acquisition dates and cost basis per tranche

  For every meaningful lot of Bitcoin you have acquired, record the date, the USD price at acquisition, and the number of BTC purchased. If you used dollar-cost averaging, you may have dozens or hundreds of small lots. At minimum, maintain a spreadsheet or record that your tax accountant can use. Why it matters: Bitcoin's cost basis determines capital gains tax when Bitcoin is sold or transferred. Without accurate basis records, your heirs or estate may be forced to use the least favorable basis method, potentially paying tens of thousands of dollars in unnecessary tax. In some cases, missing basis records have resulted in the IRS treating the entire proceeds of a sale as gain — with no deduction for original cost. Accurate records are also required if your estate elects specific lot identification to minimize gain on partial liquidations.

• ☐
  1.4 — Identify cold storage vs. active/trading stack

  Document which of your wallets are designated as long-term cold storage (rarely touched, maximum security) versus which are part of an active or trading stack (more frequently accessed, potentially connected to hot wallets). Why it matters: Cold storage and hot wallets require different access procedures, different key management, and often different custody models. Mixing them in documentation creates confusion at the worst possible time. Your executor needs to know which wallets require urgent action (active positions with open contracts, pending transactions) and which are stable long-term holds requiring careful, methodical access. The distinction also matters for custody architecture decisions in Phase 5 — ensuring your cold storage is genuinely cold and your hot wallet size is appropriate for liquidity needs.

• ☐
  1.5 — Document hardware wallet make, model, and firmware version

  For every hardware wallet in your setup, record the manufacturer (Ledger, Trezor, Coldcard, Blockstream Jade, Foundation Passport, SeedSigner, etc.), the specific model, and if possible the firmware version running at the time of documentation. Why it matters: Hardware wallet interfaces, firmware versions, and recovery procedures differ significantly between devices and versions. Your executor — and any Bitcoin recovery specialist they might engage — will need to know exactly what device they are dealing with to follow the correct procedure. Different devices support different seed phrase standards and derivation paths. A Coldcard and a Ledger Nano X, while both hardware wallets, require entirely different access procedures. Documentation of the specific device prevents costly errors during recovery and ensures the correct companion software is used.

• ☐
  1.6 — Record the derivation path used (BIP44/49/84/86)

  Document the BIP derivation standard used for each wallet: BIP44 (legacy P2PKH), BIP49 (wrapped SegWit P2SH-P2WPKH), BIP84 (native SegWit P2WPKH), or BIP86 (Taproot P2TR). The specific path (e.g., m/84'/0'/0') should be noted if you have used a non-default configuration. Why it matters: When restoring a wallet from a seed phrase, the recovery software must use the correct derivation path to find the right Bitcoin addresses. If the derivation path is incorrect, the software will restore the seed phrase successfully — but show a zero balance, because it is looking at the wrong set of addresses on the blockchain. This creates a terrifying false negative during recovery that can cause heirs to believe the seed phrase is wrong, when the seed phrase is correct and only the derivation path is off. Documenting the path prevents this. Most modern wallets use BIP84 by default; if you have older wallets or have customized settings, document it explicitly.

• ☐
  1.7 — Note which wallets are single-sig vs. multisig

  Clearly mark in your inventory which wallets are standard single-signature wallets (one seed phrase controls all funds) and which are multisig arrangements (requiring multiple keys to sign a transaction). For multisig wallets, document the configuration: 2-of-3, 3-of-5, etc., and which key in the scheme this device represents. Why it matters: Single-sig and multisig wallets have entirely different recovery requirements and operational complexity. A multisig wallet cannot be recovered with just one key — it requires the threshold number of keys plus, critically, the descriptor file (see item 2.6). If your executor does not know a wallet is multisig, they may spend weeks attempting a single-sig recovery that cannot possibly work. Worse, they may believe the seed phrase is lost or corrupted when in fact the recovery process requires multiple keys they haven't yet assembled. Labeling each wallet type clearly in the inventory is a simple step that prevents this confusion entirely.

• ☐
  1.8 — Document any Lightning Network channels

  If you run a Lightning Network node or have open Lightning channels, document the node (software used, location, approximate channel capacity) and include a note that Lightning channels must be closed — bringing funds back on-chain — before death if possible. Why it matters: Lightning Network channels are not standard Bitcoin UTXOs. They exist in a special state that requires the channel partner to cooperate in closing, or requires a force-close transaction from the node itself. If you die with open Lightning channels and your node is not accessible, the channel partner may eventually claim the funds through a force-close. More critically, your heirs need to know the Lightning node exists so they can attempt to close channels or contact the node operator. Lightning channel funds that are not on-chain at the time of death may be substantially harder to recover. If your Lightning exposure is significant, include this in your estate planning conversations with your attorney.

• ☐
  1.9 — List all exchange accounts (name, email, 2FA method)

  For each exchange or custodial platform where you hold Bitcoin — Coinbase, Kraken, Gemini, River, Swan, Strike, or others — document the platform name, the email address used to register, the 2FA method (SMS, authenticator app, hardware key), and whether you have a beneficiary designation on file. Why it matters: Exchanges have their own estate claim processes, distinct from your will or trust. Your executor needs to contact each exchange, provide a death certificate and letters testamentary, and follow the exchange's specific procedure. Without knowing which email was used to create the account, the executor may be unable to even identify the account on the platform. And 2FA — particularly authenticator app-based 2FA — can make account access impossible if the device holding the authenticator is lost. Documenting the 2FA method allows your executor to prepare the correct override procedure (typically involving the exchange's customer support escalation for deceased account holders).

• ☐
  1.10 — Document any Bitcoin held in IRAs, Roth IRAs, or 401(k)s

  If you hold Bitcoin inside a tax-advantaged retirement account — through a Bitcoin IRA provider like iTrustCapital, Alto, or Unchained, or via a Roth IRA with a self-directed custodian — document the custodian name, account type, account number (if safe to do so in context), and the beneficiary designation currently on file. Why it matters: Bitcoin in retirement accounts is subject to different rules than Bitcoin in self-custody or exchange accounts. The beneficiary designation on the retirement account overrides your will entirely — it does not matter what your will says, the account goes to whoever is named as beneficiary. If that designation is outdated (an ex-spouse, a deceased parent, or no one at all), your estate plan fails at this asset regardless of every other document you have. Additionally, retirement account Bitcoin has different tax treatment at death — inherited IRAs have required minimum distribution rules that can significantly affect after-tax value to heirs. Your estate planning attorney must know about all retirement account Bitcoin.

The inventory tells your executor what you have. Phase 2 ensures they can actually access it. Key security and backup is where most Bitcoin estate plans fail — either because the backup does not exist, cannot be found, or is incomplete in a way that makes recovery impossible.

• ☐
  2.1 — Back up seed phrases to durable metal (not paper only)

  Your 12- or 24-word BIP39 seed phrase is the master key to your Bitcoin. If stored only on paper, it is vulnerable to fire, flood, moisture, and physical degradation. Back up every seed phrase to a durable metal medium — stamped or engraved stainless steel, titanium, or a purpose-built product like Cryptosteel, Bilodeau, or a DIY stainless steel letter punch. Why it matters: Paper seed phrases have been lost to house fires, basement floods, and simple decay. Metal backups survive fires that reach temperatures far above any residential fire and are impervious to water. The cost of a metal backup is trivial — $30 to $150 for a quality solution — compared to the value of what it protects. This is not optional redundancy. For estates where Bitcoin represents significant wealth, it is the minimum acceptable standard. One paper backup plus one metal backup in a different location is the baseline. Two metal backups in different locations is better.

• ☐
  2.2 — Store seed phrase backups in at least 2 geographically separate locations

  Never store all copies of a seed phrase in the same physical location. A minimum of two geographically separate locations is required — a primary location (home safe, secured cabinet) and a secondary location (trusted family member's home, attorney's office, secure storage facility). The locations should be far enough apart that a single disaster — fire, flood, theft — cannot compromise both copies simultaneously. Why it matters: Geographic separation is the insurance policy for the insurance policy. If your home is destroyed by fire and your seed phrase backup is only stored at home, both the hardware wallet and the backup are gone — and the Bitcoin is permanently inaccessible. Many Bitcoin inheritance failures trace back to a single location for all backups. The principle of geographic separation costs nothing but planning, and it is the single most effective way to prevent permanent Bitcoin loss from physical disaster.

• ☐
  2.3 — Test seed phrase backups (restore a watch-only wallet)

  Do not assume your seed phrase backup is correct — verify it. The most practical way to test without exposing your funds: use your seed phrase to restore a watch-only wallet (using Sparrow, Electrum, or the hardware wallet's own verification function) and confirm the correct Bitcoin addresses appear. If addresses match your expected wallet, the backup is valid. Why it matters: Transcription errors in seed phrases are more common than most people assume. A misread word, a skipped word, or a word recorded in the wrong position creates a seed phrase that appears complete but opens a completely different wallet — or no valid wallet at all. The only way to know your backup is correct is to verify it against the actual wallet it represents. This test should be done when the backup is first created, and verified again at each annual review. An untested backup is not a backup — it is a piece of metal with words on it whose validity is unknown.

• ☐
  2.4 — Store hardware wallet PINs separately from seed phrases

  Your hardware wallet PIN unlocks the device for daily use. It should be documented and stored in a location that is different from where the seed phrase backup is stored — same document or same location. Why it matters: Storing the PIN with the seed phrase creates an unnecessary single point of compromise. Anyone who finds the combined document has both the master key (seed phrase) and the device access code (PIN). More importantly: the PIN and seed phrase serve different recovery purposes. If the device is lost, the seed phrase alone is sufficient to restore the wallet on a new device — the PIN is irrelevant. If the device is found but inaccessible, the PIN alone helps. Separating them also prevents confusion in documentation. Your executor should understand that the seed phrase is the ultimate backup and the PIN is device-specific — not a substitute for the seed phrase.

• ☐
  2.5 — Document the passphrase (25th word) separately with clear instructions

  A BIP39 passphrase — sometimes called the 25th word — is an optional additional word (or phrase) added to the 24-word seed. It creates a completely separate wallet with a different set of addresses. If you use a passphrase, it must be documented separately from the seed phrase, and the documentation must make clear: that a passphrase exists, what it is, and that it must be entered along with the seed phrase to access the correct wallet. Why it matters: This is one of the most common causes of Bitcoin inheritance failure we have observed. A holder uses a passphrase for security — an excellent practice — but does not document it, or documents it in the same secure storage as the seed phrase without identifying it clearly. The heirs use the seed phrase to restore the wallet and see a zero balance — because without the passphrase, they are looking at the wrong wallet. They conclude the seed phrase is wrong. The Bitcoin is presumed lost. It is not lost — it is sitting in the passphrase-protected wallet, inaccessible because the one additional piece of information was never documented. Document the passphrase. Do it now.

• ☐
  2.6 — Back up the multisig descriptor file

  If you use any multisig wallet setup, the descriptor (also called the wallet file or output descriptor) is a separate piece of data that describes the complete multisig configuration: all the extended public keys, the threshold, and the script type. This file is distinct from any individual seed phrase and must be backed up independently. Why it matters: This is the most technically underappreciated item on this entire checklist — and arguably the most catastrophic oversight in multisig estate planning. In a 2-of-3 multisig setup, you need two of the three keys AND the descriptor to spend funds. Without the descriptor, a wallet coordinator cannot reconstruct the multisig script, and cannot determine which addresses belong to the wallet. Even if your heirs have all three keys, they cannot spend the Bitcoin if the descriptor is missing. Some software can attempt to reconstruct the descriptor from extended public keys, but this is not guaranteed and may fail for custom configurations. The solution is simple: export and back up your wallet file or output descriptor from your coordinator software (Sparrow, Specter, Nunchuk, etc.) at the same time you create the multisig setup, and store it at a different location from any individual key.

• ☐
  2.7 — Confirm no seed phrases are stored digitally

  Verify that no copy of any seed phrase exists in digital form: no photos on your phone, no screenshots, no notes app, no cloud storage, no email drafts, no encrypted files on your computer, no password manager entries, no text messages. Every digital copy of a seed phrase is a security vulnerability and an unnecessary risk. Why it matters: Digital storage of seed phrases creates multiple threat vectors: cloud storage accounts can be compromised; phone photos can sync to services you've forgotten; email drafts survive even after you think you've deleted them; computer files can be recovered after deletion. Beyond security, digital storage creates estate planning complexity — if a seed phrase exists in your email, your executor may need court orders to access that email account after your death, adding months of delay to the estate process. The estate plan is designed to provide secure, documented physical access to seed phrases. Any digital copy undermines that security model without adding estate planning value.

• ☐
  2.8 — Ensure at least one trusted person knows where to find backup documentation

  At minimum one trusted person — your executor, successor trustee, or a close family member — must know the physical location of your seed phrase backup documentation. They do not need to know the seed phrase itself, and ideally they do not. They need to know where to look: the safe, the drawer, the attorney's sealed envelope, the specific person holding the backup at the secondary location. Why it matters: Documentation stored in a location only you know about is documentation that disappears when you die. No matter how well-constructed your backup, if your executor does not know the backup exists and where it is, the Bitcoin may be permanently lost during estate administration. The trusted person should not be the only safeguard — your Letter of Instruction should also reference backup locations — but a living person who knows where to look provides a crucial human failsafe. This is especially important if your primary and secondary backup locations are not obvious (e.g., not a home safe, but a trusted friend's home in another city).

• ☐
  2.9 — Test whether your heir could actually access the funds

  Do not assume your documentation is sufficient — test it. Set up a small wallet with a nominal amount of Bitcoin (even $50 or $100) and walk your primary heir through the complete recovery process using only the information provided in your Letter of Instruction and backup documentation, without your guidance. Watch where they get stuck. Why it matters: This exercise reveals every gap in your documentation that you cannot see because you already know the answers. The most common gaps discovered in these tests: the heir did not know which wallet software to download, did not understand how to enter a BIP39 seed phrase, did not know the derivation path, did not have the passphrase, or did not understand the difference between the wallet PIN and the seed phrase. Each of these gaps, if unaddressed, is a potential pathway to permanent loss. The rehearsal is also an educational experience for the heir — they build confidence and competence before facing a high-stakes, high-stress real recovery situation. If your heir cannot complete the test recovery, your estate plan is incomplete regardless of how many legal documents you have signed.

• ☐
  2.10 — Schedule annual key security review

  Set a recurring annual date — the first of January, your birthday, a family anniversary — to physically verify the existence and readability of every seed phrase backup, test that the hardware wallet still powers on, confirm the passphrase documentation is accurate, and re-read the Letter of Instruction to ensure it reflects your current custody setup. Why it matters: Custody setups change. Hardware wallets age. Metal backups can corrode or become difficult to read. Seed phrase storage locations change. Annual verification catches the small degradations — a partially corroded backup, a hardware wallet with a failing battery, a storage location that has changed — before they compound into a failure. The review is also the prompt to update any documentation that has become stale due to changes in your setup. Make it a formal calendar event, not an intention. The families who complete annual reviews are the ones whose estates are recoverable.

Technical key documentation without legal structure means your heirs can access the Bitcoin but may face tax, probate, and family conflict issues getting it distributed correctly. Legal structures provide the framework for who gets what, who decides, and how disputes are resolved.

• ☐
  3.1 — Update your will to reference Bitcoin holdings

  Your will should include a provision specifically addressing digital assets, including Bitcoin. The language should be general — "my Bitcoin and other digital assets held in self-custody wallets, hardware devices, and custodial exchange accounts" — not specific to particular wallet addresses or account numbers, which change. Why it matters: Without a will provision, Bitcoin may be treated as residuary estate (passed via the residuary clause, which may not reflect your intent), or may be subject to intestacy laws if there is no will at all. More practically, the executor needs legal authority to act — to contact exchanges, to manage hardware wallets, to coordinate with custodians. A will provision grants that authority explicitly. It should also reference the Letter of Instruction by name without incorporating its contents, so the LOI can be updated freely without requiring a will amendment. Some states have specific digital asset statutes (RUFADAA-compliant laws) that provide this authority by default, but an explicit will provision is cleaner and avoids ambiguity.

• ☐
  3.2 — Name a trustee for any Bitcoin held in trust

  If you hold Bitcoin inside a trust — revocable living trust, irrevocable trust, or a purpose-built Bitcoin trust — name a trustee and at least one successor trustee. The trustee should be someone with both the legal competence to administer the trust and the technical willingness to learn how to manage Bitcoin custody. Why it matters: A trustee who is unwilling or unable to interact with Bitcoin custody creates an immediate bottleneck at the time of trust administration. If the trustee cannot operate a hardware wallet or does not understand the difference between custodial and self-custody Bitcoin, the trust may be forced to sell Bitcoin at the worst possible time to satisfy a requirement of the trust — simply because no one in the administration chain knows how to maintain the custody. Name a Bitcoin-literate trustee if possible, or provide for professional trust administration with explicit authority to engage a Bitcoin custody specialist at trust expense.

• ☐
  3.3 — Verify trust documents include digital asset provisions

  Any trust holding Bitcoin must include explicit provisions authorizing the trustee to: hold digital assets, acquire digital assets, transfer digital assets, engage custodians and Bitcoin specialists, and manage private keys or delegate key management to qualified custodians. Trust documents written before approximately 2018 almost certainly lack these provisions. Why it matters: Without explicit digital asset authority in the trust document, a trustee may face legal exposure for holding Bitcoin in trust — some older trust interpretations would consider this outside the trustee's permissible investments. More practically, the trustee needs clear written authority to do everything that Bitcoin management requires: interacting with hardware wallets, transacting on exchanges, engaging with collaborative custodians. Boilerplate "investment authority" language from a 2015 trust document is probably insufficient. Have your attorney review and update with explicit digital asset language.

• ☐
  3.4 — Ensure your power of attorney includes explicit digital asset authority

  A durable power of attorney (POA) allows your designated agent to act on your behalf if you become incapacitated. For Bitcoin holders, the POA must explicitly include authority to manage digital assets — to access accounts, move Bitcoin, interact with custodians, and maintain private key storage. Generic "financial assets" language may not be sufficient. Why it matters: Incapacity is a more common estate planning event than death, and its planning requirements are just as urgent. If you become incapacitated without a POA that explicitly covers digital assets, your agent may be legally prohibited from accessing your exchange accounts or wallets — even to rebalance, pay bills, or satisfy required distributions from a Bitcoin IRA. In states that have adopted RUFADAA (most states), the law provides some default authority, but a POA with explicit digital asset language avoids ambiguity and potential legal challenge from custodians who require specific written authority.

• ☐
  3.5 — Review beneficiary designations on Bitcoin IRA and retirement accounts

  Log in to every Bitcoin IRA or self-directed retirement account and verify the primary and contingent beneficiary designations on file. Confirm that the named beneficiaries are current, consistent with your estate plan, and still living. Why it matters: Beneficiary designations override your will. If your Bitcoin IRA names a beneficiary who is now your ex-spouse, or a parent who predeceased you, or simply has no contingent beneficiary named, the account may pass incorrectly — or go through probate, which eliminates the tax advantage of an IRA entirely. This is one of the most common and most easily corrected estate planning mistakes. A 10-minute login to each retirement account platform to review and update beneficiary designations can save your estate enormous complexity and potentially hundreds of thousands of dollars in tax and administrative costs.

• ☐
  3.6 — Evaluate LLC or trust formation for significant holdings

  For Bitcoin holders with substantial positions — generally over $500,000 in Bitcoin — consider whether holding Bitcoin in an LLC or a more complex trust structure (irrevocable trust, dynasty trust, or directed trust) is appropriate. Consult with a Bitcoin-literate estate planning attorney who can evaluate your specific situation, state of residence, and estate tax exposure. Why it matters: An LLC holding Bitcoin provides operational flexibility (multiple members can have authorized access), potential liability protection, and cleaner transfer mechanics than personal ownership — particularly for complex multisig setups where multiple parties need signing authority. Irrevocable trust structures can remove appreciating Bitcoin from the taxable estate entirely, a strategy that becomes more powerful as Bitcoin's price increases. The right structure depends on your estate size, family situation, and jurisdiction — but for holders over the $500K threshold, the conversation is worth having now, while more planning options are available.

• ☐
  3.7 — Consider Wyoming, Nevada, or South Dakota jurisdiction for entity structures

  If you are forming a trust or LLC to hold Bitcoin, the jurisdiction of formation matters significantly. Wyoming, Nevada, and South Dakota have enacted some of the most favorable laws for digital assets, trust formation, and multi-generational wealth planning in the United States. Why it matters: Wyoming has specific Bitcoin and digital asset statutes that provide legal clarity for custodianship, self-custody, and trust administration of digital property. It also allows for perpetual trusts with no rule against perpetuities — ideal for multi-generational Bitcoin wealth transfer. South Dakota similarly allows dynasty trusts with no state income tax on trust income. Nevada's trust laws offer strong asset protection features. Any of these jurisdictions can be used for trust or LLC formation even if you do not live there — you simply need a registered agent or directed trustee in the jurisdiction. This is a specialized area of law; engage an attorney who has formed digital asset trusts in these jurisdictions specifically.

• ☐
  3.8 — Provide your attorney with the trust/will — but never the keys

  Your estate planning attorney should have an executed copy of your will, trust documents, and power of attorney. They should be listed as a contact in your Letter of Instruction. They should not, under any circumstances, have your seed phrases, private keys, hardware wallet PINs, or passphrase. Why it matters: This distinction is critical: the attorney manages legal documents, not Bitcoin keys. Combining legal and technical custody in one person or location creates an enormous security and estate planning risk. If the attorney's office is compromised, your Bitcoin is at risk. If the attorney dies or dissolves the practice, the key custody chain is disrupted. Keep legal document custody and Bitcoin key custody in completely separate custody chains, connected only through a clearly documented Letter of Instruction that references both. The attorney's job is to know the legal structure. Your executor's job is to follow the LOI to the keys. These should never be the same document or the same location.

• ☐
  3.9 — Evaluate a no-contest clause if family conflict is possible

  A no-contest clause (also called an in terrorem clause) provides that any beneficiary who contests the will or trust loses their inheritance entirely. If your estate plan involves a complex Bitcoin distribution or if there are family members who might challenge your intentions, discuss a no-contest clause with your attorney. Why it matters: Bitcoin estates can attract disputes — particularly from family members who do not understand Bitcoin and suspect it is worth more than disclosed, or who believe they should receive a larger share. Will contests and trust litigation are expensive, time-consuming, and can freeze access to Bitcoin for years during the dispute. A no-contest clause reduces (but does not eliminate) the likelihood of frivolous challenges by making the cost of a failed challenge equal to the entire inheritance. Not all states enforce no-contest clauses, and their use requires careful attorney guidance, but for families with potential conflict dynamics, the provision is worth evaluating.

• ☐
  3.10 — Draft a letter of wishes for your trustee and heirs

  A letter of wishes is a non-binding private document addressed to your trustee, executor, or heirs explaining your intentions, values, and guidance for managing your Bitcoin wealth. Unlike a will, it does not require attorney drafting, is not filed with a court, and can be updated at any time. Why it matters: Legal documents constrain what the trustee and executor must do — but they cannot express what you would want in situations the documents did not anticipate. A letter of wishes might explain your philosophy on Bitcoin — whether you want heirs to hold long-term or are comfortable with liquidation, whether you have concerns about a particular family member's readiness to receive a large Bitcoin inheritance, or what role you hope Bitcoin wealth will play in the family's next generation. For Bitcoin families with strong convictions about sound money, long-term holding, or specific allocation principles, the letter of wishes translates those convictions into guidance that survives you, even without legal enforcement.

Bitcoin's appreciation creates tax complexity that traditional estate planning rarely has to handle — cost basis tracking across hundreds of lots, capital gains embedded in long-term holdings, and estate tax exposure that can change dramatically with price movements. Phase 4 ensures the tax dimension of your Bitcoin estate is planned, not improvised.

• ☐
  4.1 — Ensure cost basis records are complete for every lot

  Compile a complete record of every Bitcoin acquisition: date purchased, price in USD at time of purchase, quantity of BTC, and platform or method of acquisition. For DCA buyers, this may mean hundreds of records. Reconcile against exchange histories, on-chain transactions, and personal records. Why it matters: Without accurate cost basis records, your estate — or your heirs — will face an uphill battle with the IRS when Bitcoin is ultimately sold. If basis is unknown, the IRS can take the position that basis is zero, treating the entire sale proceeds as gain. For large, appreciated Bitcoin positions, this error can cost hundreds of thousands of dollars in avoidable tax. The step-up in basis rules that apply at death make accurate pre-death records important for determining the stepped-up basis correctly, and for estates that mix Bitcoin with different acquisition dates and prices, specific lot identification requires a complete basis record to be meaningful.

• ☐
  4.2 — Select and document your tax lot accounting method

  Choose and formally document whether you use FIFO (first-in, first-out), LIFO (last-in, first-out), HIFO (highest-in, first-out), or specific lot identification for capital gains purposes. Communicate this election to your tax accountant and ensure it is applied consistently. Why it matters: The tax lot method you use significantly affects your capital gains when you sell Bitcoin — sometimes by tens of thousands of dollars on a single transaction. FIFO (the IRS default) sells your oldest, lowest-basis coins first, maximizing long-term gain recognition. HIFO (highest-cost basis first) minimizes current gain by selling the lots with the largest basis. Specific identification allows surgical optimization lot-by-lot but requires complete records. Most Bitcoin tax software (Koinly, CoinTracker, TaxBit) supports all of these, but the method must be selected before the first taxable sale in a given tax year and applied consistently. Document your method so your estate and heirs continue the same approach.

• ☐
  4.3 — Review unrealized gains annually for gifting opportunities

  Each year, review your Bitcoin position to assess unrealized gains and losses across all lots. Identify positions with significant embedded gain (good candidates for gifting to heirs who will receive a step-up at death, or for charity) and any lots in a loss position (candidates for tax-loss harvesting). Why it matters: Proactive management of Bitcoin's tax lot structure — across potentially decades of accumulation — is one of the highest-leverage tax planning activities available to Bitcoin holders. By identifying which lots have the highest embedded gain, you can make informed decisions about what to hold, what to gift, and what to donate. For heirs who will inherit Bitcoin at your death and receive a step-up in basis, the pre-death decision of which lots to keep (let step up) versus which to give during life (for other planning reasons) is worth examining each year with your advisor. This is not a set-it-and-forget-it analysis — Bitcoin price volatility means the landscape changes substantially year to year.

• ☐
  4.4 — Utilize the annual gift tax exclusion ($18,000/recipient in 2026)

  The federal annual gift tax exclusion allows you to give up to $18,000 per recipient per year (indexed for inflation; verify current amount for the applicable year) without using any lifetime gift and estate tax exemption. For Bitcoin holders, this means gifting appreciated Bitcoin to heirs, trusts, or other recipients within the annual exclusion amount. Why it matters: Systematic annual gifting is one of the most powerful estate tax reduction strategies available, and it compounds remarkably over time. A married couple giving $36,000 per year to a child ($18,000 from each spouse) transfers $360,000 over 10 years — completely free of gift tax. Giving appreciated Bitcoin within the annual exclusion transfers the Bitcoin and its future appreciation outside the taxable estate. The Bitcoin gifted retains the donor's original basis (the recipient does not get a step-up), so this strategy works best for gifts to recipients who are not planning to sell immediately. Structure the gifts early in the year when possible.

• ☐
  4.5 — Evaluate GRAT strategy if estate approaches exemption thresholds

  A Grantor Retained Annuity Trust (GRAT) is an irrevocable trust designed to transfer appreciation out of your taxable estate with minimal gift tax. You fund the GRAT with Bitcoin, receive annuity payments back over a set term, and if Bitcoin appreciates above the IRS hurdle rate, the excess appreciation passes to heirs gift-tax free. Under 2026 OBBBA thresholds, the relevant federal exemption is approximately $15M individual / $30M couple — evaluate a GRAT analysis if your estate is approaching these levels. Why it matters: A GRAT is particularly powerful for an asset like Bitcoin that has demonstrated dramatic appreciation potential. If Bitcoin doubles during a 2- or 3-year GRAT term, the excess over the IRS 7520 hurdle rate (currently in the 4–5% range) passes to heirs completely free of estate and gift tax — regardless of how large that appreciation is. The risk: if Bitcoin declines during the term, the GRAT "fails" — it expires with no benefit, but you lose nothing other than legal fees. Rolling short-term GRATs (sometimes called "zeroed-out GRATs") can be structured to take repeated bets on Bitcoin appreciation with zero downside to the estate plan. Engage an estate planning attorney with GRAT experience to evaluate the current rate environment and your specific situation.

• ☐
  4.6 — Evaluate a Charitable Remainder Trust (CRT) if charitably inclined

  A Charitable Remainder Trust (CRT) allows you to contribute appreciated Bitcoin, receive an immediate charitable deduction, avoid immediate capital gains tax on the contribution, receive a stream of income payments for a term of years or life, and ultimately pass the remainder to one or more charities. Why it matters: For Bitcoin holders with large, highly appreciated positions who are charitably inclined, a CRT can be extraordinarily efficient. Contributing Bitcoin with a very low cost basis to a CRT avoids the immediate capital gains tax on that appreciation — the trust sells the Bitcoin tax-free and reinvests the proceeds, paying the income stream to the donor from the full pre-tax amount. The combination of the charitable deduction, the deferral of gain, and the income stream can result in significantly more wealth transferred than selling the Bitcoin, paying capital gains, and donating cash. This strategy requires careful planning and is not for everyone — but for the right Bitcoin holder, it is one of the most powerful tools in the estate planning toolkit.

• ☐
  4.7 — Evaluate Donor Advised Fund contributions in high-gain years

  A Donor Advised Fund (DAF) allows you to make an irrevocable contribution of appreciated Bitcoin, claim an immediate charitable deduction for the fair market value of the Bitcoin at contribution, and then recommend grants to qualified charities over time. The DAF sells the Bitcoin and invests the proceeds, with no capital gains to you at the time of contribution. Why it matters: In years where Bitcoin has appreciated dramatically — and your income is high — a DAF contribution can provide significant tax relief while accomplishing charitable goals. The combination of a full fair-market-value deduction (no capital gains on the appreciation) plus flexibility on when and how to distribute the grants makes DAFs one of the most efficient vehicles for Bitcoin philanthropy. Fidelity Charitable, Schwab Charitable, and several Bitcoin-native DAF platforms (including The Giving Block) accept direct Bitcoin contributions. The deduction is limited to 30% of adjusted gross income for appreciated property; excess can be carried forward for five years.

• ☐
  4.8 — Review Bitcoin mining depreciation strategy if applicable

  If you are involved in Bitcoin mining — directly or through hosted mining arrangements — review the depreciation schedule for mining equipment, the treatment of Bitcoin received as mining income, and the interaction between mining deductions and your overall tax picture. Bonus depreciation rules, which allow accelerated deduction of equipment costs, have changed in recent years and require current-year analysis. Why it matters: Bitcoin mining is unique among Bitcoin acquisition strategies in that it generates deductible expenses — equipment, electricity, facility costs — that can significantly offset the income from mining rewards. When structured correctly, mining can be a powerful tax strategy: mining equipment depreciation (potentially including bonus depreciation on new equipment) can generate large deductions in the year of purchase, while the Bitcoin received as mining income has a fair-market-value cost basis at receipt. Compared to buying Bitcoin with after-tax dollars (zero deduction), mining Bitcoin with pre-tax dollars (significant deductions) creates a meaningful after-tax cost advantage. This strategy is worth reviewing every year if you have mining operations of any scale.

• ☐
  4.9 — Review state estate tax exposure (MA, OR, WA, IL, MN, RI)

  If you live in Massachusetts, Oregon, Washington, Illinois, Minnesota, Rhode Island, or any other state with its own estate tax, calculate your exposure at current Bitcoin price. Several of these states have exemption thresholds well below the federal level — Massachusetts and Oregon at $1 million, Washington at approximately $2.2 million — and rates that can reach 16–20% of the estate above the exemption. Why it matters: A Bitcoin holder with 2 BTC at $100,000/BTC and $1 million in other assets has a $1.2 million taxable estate for Massachusetts purposes — fully in state estate tax territory with potentially $20,000–$40,000 in Massachusetts estate tax at death. That same holder may be completely under the federal estate tax threshold. State estate tax planning — including potential domicile change, trust structures, and gifting strategies — may be the most urgent planning priority for Bitcoin holders in high-tax states, even if federal planning is not yet relevant. Do not assume that being under the federal threshold means no estate tax exposure.

• ☐
  4.10 — Model step-up in basis strategy (hold vs. gift vs. trust timing)

  Assets held at death receive a step-up in cost basis to fair market value on the date of death — eliminating the embedded capital gain for income tax purposes. Bitcoin with very low cost basis that you plan to hold until death benefits from this step-up. Bitcoin you plan to give during life (or sell) does not benefit from it. Model the trade-off for your specific situation. Why it matters: For Bitcoin with very large embedded gains — bought at $10,000 or $5,000 per BTC and now worth $100,000+ — the step-up in basis at death is worth a substantial amount in avoided capital gains tax. A holder who bought 10 BTC at $5,000 and holds until death at $150,000 would eliminate $1,450,000 in embedded gain ($14,500 per BTC gain × 10 BTC) from the heir's future tax bill. However, the step-up is not always the optimal strategy — the estate tax on the appreciated value may exceed the capital gains tax saved, particularly in high-exemption states. Your advisor should model both scenarios at current and projected Bitcoin prices to determine which combination of lifetime gifts, charitable contributions, and deathtime transfers produces the best after-tax outcome for your family.

How you hold Bitcoin is as important as documenting that you hold it. Custody architecture — the combination of wallet types, security levels, and access mechanisms — must be appropriate for your holding size and recoverable by your heirs. Phase 5 audits your custody setup against best practices for estate planning.

• ☐
  5.1 — Define and document cold storage vs. hot wallet allocation

  Establish a written policy for how much Bitcoin you hold in cold storage (air-gapped hardware wallets, never connected to the internet) versus hot wallets (software wallets, exchange accounts, Lightning nodes). Document the target allocation and the current actual allocation, and set criteria for when you would adjust the split. Why it matters: Cold storage and hot wallets have different risk profiles and different estate planning requirements. Bitcoin in cold storage is maximally secure against remote theft but requires more complex physical access procedures at death. Bitcoin in hot wallets is more accessible but is at greater risk of loss through exchange failure or software vulnerability. For estate planning, the allocation matters because your executor will need different procedures for each type. A written policy also prevents the gradual accumulation of Bitcoin in "temporary" hot storage that never gets moved back to cold — a common drift pattern that increases risk over time without a deliberate decision to do so.

• ☐
  5.2 — Implement multisig for holdings over $250,000

  For Bitcoin positions above approximately $250,000 in value, evaluate implementing a multisig custody setup — typically 2-of-3 or 3-of-5 — where spending requires multiple independent key signatures. This eliminates the single point of failure inherent in single-signature wallets. Why it matters: A single-signature wallet has one critical failure mode: anyone who obtains the seed phrase has complete access to all funds. For large holdings, this single point of failure is unacceptable. Multisig distributes that risk — a thief must compromise multiple separate keys to steal Bitcoin, and your heirs must assemble multiple keys to recover Bitcoin. This also eliminates the "one wrong step" catastrophe: a multisig setup is tolerant of one lost or compromised key as long as the threshold can still be met from the remaining keys. For estate planning purposes, multisig also allows you to architect key distribution — different family members, different locations, different custodians — in a way that matches your estate plan structure precisely. The trade-off is added complexity, which is why documentation (especially the descriptor file from item 2.6) is so critical.

• ☐
  5.3 — Diversify hardware wallet brands in multisig setup

  In a multisig setup, use hardware wallets from different manufacturers for at least two of the signing keys — for example, a Coldcard, a Ledger, and a Trezor in a 2-of-3 setup, rather than three Ledgers. Why it matters: Hardware wallet manufacturers can go out of business, issue firmware with critical security vulnerabilities, or be compromised at the supply chain level. Using multiple brands in a multisig setup ensures that a failure, vulnerability, or discontinuation of one brand does not affect the entire multisig security model. If one manufacturer issues a firmware update that inadvertently corrupts wallet functionality, the holder with three devices from that manufacturer is in a more difficult position than the holder who can still sign transactions with devices from the two unaffected manufacturers. Brand diversification in multisig is a form of hardware risk diversification — the same principle as not putting all your financial assets with one institution.

• ☐
  5.4 — Back up coordinator software configuration (Sparrow, Specter, Nunchuk)

  Export and back up your wallet configuration file from your multisig coordinator software — Sparrow Wallet, Specter Desktop, Nunchuk, or whichever coordinator you use. This file contains the full wallet descriptor needed to reconstruct the multisig setup. Store it separately from any individual key backup, with a clear label. Why it matters: This is the practical implementation of item 2.6 (back up the multisig descriptor). The coordinator software configuration file is the most complete and accessible form of the descriptor — it includes all extended public keys, the script type, and the threshold configuration in a format that can be directly imported into compatible coordinator software. Without it, reconstructing the multisig configuration requires technical expertise and may not be possible at all for custom configurations. Back it up at the time of wallet creation, and update the backup whenever the wallet configuration changes (adding or rotating a key). Store it on a USB drive or printed QR code, not in the cloud.

• ☐
  5.5 — Evaluate collaborative custody for holdings over $1 million

  Collaborative custody services — providers like Unchained Capital, Casa, or Theya — offer managed multisig arrangements where the provider holds one key in a 2-of-3 or similar setup, but cannot move funds unilaterally. You retain majority control, while the provider offers key recovery services, inheritance assistance, and technical support. Why it matters: Pure self-custody multisig, while maximally decentralized, places the entire operational and estate planning burden on the holder and their heirs. Collaborative custody solves the estate planning problem elegantly: the provider's key can be used by your heirs (with appropriate authorization, typically death certificate and legal documentation) as one of the signing keys, reducing the technical burden on heirs who may not be Bitcoin-savvy. The provider also offers estate planning assistance, Letter of Instruction templates, and sometimes direct coordination with attorneys and executors. For holdings over $1 million, the modest annual fee for collaborative custody is justified by the estate planning benefit alone — before even considering the security benefits.

• ☐
  5.6 — Evaluate institutional custody for holdings over $5 million

  For Bitcoin holdings above $5 million, evaluate regulated institutional custody solutions — Coinbase Custody, Anchorage Digital, Fidelity Digital Assets, BitGo, or similar — that provide insurance coverage, regulatory compliance, fiduciary-grade custody standards, and formal estate administration processes. Why it matters: Institutional custodians operate under regulatory oversight, maintain insurance for digital assets, have formal estate and succession procedures, and are equipped to work directly with estate attorneys and courts. At the $5 million threshold, the complexity of managing a self-custody or collaborative custody arrangement entirely on your own — and ensuring that arrangement survives your incapacity or death — begins to justify the custody fees and the operational relationship with a regulated institution. Institutional custody also provides a more familiar interface for bank trustees, trust companies, and estate attorneys who may be less comfortable with the operational aspects of hardware wallet self-custody. The trade-off is reduced sovereignty in exchange for institutional reliability and process.

• ☐
  5.7 — Minimize exchange holdings to what's needed for liquidity

  Reduce exchange-custodied Bitcoin to the minimum amount required for your active trading, liquidity, and short-term spending needs. Move the remainder to self-custody cold storage or a custody architecture appropriate for your holding size. Document the rationale for the exchange allocation in your IPS. Why it matters: Exchanges are counterparty custodians — when your Bitcoin is on an exchange, the exchange holds it on your behalf. Exchange failures (FTX, Celsius, Mt. Gox) have resulted in significant, permanent losses to customers who held more than needed on exchange platforms. From an estate planning perspective, exchange-custodied Bitcoin requires a different (and sometimes more complex) estate claim process than self-custodied Bitcoin — involving the exchange's specific estate administration team and the production of legal documentation. Minimizing exchange holdings reduces both security and estate planning complexity. The only Bitcoin that should stay on exchange is what you genuinely need within the near term for liquidity, trading, or operational purposes.

• ☐
  5.8 — Schedule annual custody architecture review

  Set a calendar reminder to review your entire custody architecture annually: hardware wallet firmware updates, multisig key health, collaborative custody relationship status, exchange account standing, and whether the overall custody structure remains appropriate for your current holdings size and life situation. Why it matters: Bitcoin custody technology evolves rapidly. Firmware updates can fix security vulnerabilities or introduce new features. Multisig coordinator software receives significant updates that may change optimal procedures. Collaborative custody providers may change terms, improve services, or in rare cases, exit the business. Hardware wallets develop hardware faults over time. The annual review ensures you catch these changes before they become crises, and that your custody architecture remains calibrated to your current holdings value and estate planning goals. It is also the trigger for updating your Letter of Instruction if anything has changed.

The most comprehensive documentation in the world does not help heirs who do not know how to use it. Phase 6 ensures the humans in your succession plan — your heirs, trustee, executor — have the knowledge and resources to actually receive and manage your Bitcoin.

• ☐
  6.1 — Ensure at least one heir understands Bitcoin basics

  At minimum one primary heir or successor should understand the foundational concepts: what a private key is, what a seed phrase is, why "not your keys, not your coins" is a rule and not a preference, the difference between custodial and self-custodied Bitcoin, and why digital copies of seed phrases are dangerous. They do not need to be technical experts — they need to understand enough to follow documentation and know when to ask for help. Why it matters: Bitcoin estate planning documentation is only as useful as the heir's ability to read and follow it. A Letter of Instruction that says "restore the wallet using the seed phrase in Location A" is meaningless to someone who does not know what a seed phrase is or what "restoring a wallet" means. Even basic Bitcoin literacy — a few hours of education — dramatically increases the probability that an heir can execute the recovery process or intelligently engage a Bitcoin specialist who will complete it on their behalf. This is perhaps the highest-leverage single item on this entire checklist: educated heirs do not panic, do not make hasty decisions, and do not inadvertently destroy access to funds in the recovery process.

• ☐
  6.2 — Have heirs practice a test recovery with a small amount

  Create a small test wallet — fund it with a nominal amount of Bitcoin, $50 to $200 — and have your primary heir conduct a complete mock recovery using only the documentation you have prepared. Watch where they encounter friction, confusion, or uncertainty, and use those observations to improve your documentation. Why it matters: A test recovery is the live fire drill for your estate plan. Documentation that seems clear to you — who already knows all the steps — may be confusing or ambiguous to someone encountering these procedures for the first time under stress. The test reveals gaps you cannot see because you cannot unknow what you know. Common gaps discovered in these tests: the heir did not know which software to download, did not understand how to enter the seed phrase correctly, did not know the derivation path to select, did not have the passphrase, or did not understand that the wallet PIN is not the same as the seed phrase. Every gap identified in the test is a gap that would have cost real Bitcoin in a real recovery. Fix the gaps. Update the documentation. Run the test again if needed. An estate plan that passes a live test recovery is an estate plan that works.

• ☐
  6.3 — Provide heir education resources

  Assemble a curated set of Bitcoin education resources specifically for heirs who are not already Bitcoin-literate: a short reading list, a trusted online resource or two, and contact information for a Bitcoin advisor your heirs can call. Consider including: The Bitcoin Standard by Saifedean Ammous (conceptual foundation), Cryptoasset Inheritance Planning by Pamela Morgan (the definitive book on exactly this topic), and documentation from your specific hardware wallet manufacturer on the recovery process. Why it matters: When a family member dies, the surviving heirs are processing grief while simultaneously being asked to navigate an unfamiliar technical and legal landscape. The stress and emotional weight of this moment makes the educational gap feel much larger. A curated reading list and a trusted contact reduces the barrier to getting help. It also signals to the heir that you anticipated the learning curve and made provision for it — which builds confidence rather than panic. If your heir knows there is a specific person they can call for Bitcoin guidance, they are less likely to make impulsive decisions (like selling Bitcoin immediately to simplify the estate) that may not reflect your intentions or their long-term financial interests.

• ☐
  6.4 — Name a successor trustee if Bitcoin is held in trust

  If your Bitcoin is held in any trust — revocable living trust, irrevocable trust, or a purpose-built digital asset trust — name at least one successor trustee (and ideally a second successor trustee as a backup) who will take over management of the Bitcoin if the primary trustee cannot serve. The successor trustee should be named in the trust document itself, not just in a side letter. Why it matters: The trustee succession chain is the operational continuity plan for your Bitcoin after death. If the primary trustee is unwilling, incapacitated, or deceased, the successor trustee must be ready to step in immediately — including taking over custody of any hardware wallets, keys, or collaborative custody relationships. A gap in the trustee succession chain means the trust may require court intervention to appoint a trustee, which can freeze access to the Bitcoin for months. Name the succession chain proactively, verify that named successors are willing and aware, and confirm they have enough Bitcoin literacy to manage or delegate the technical aspects of custody.

• ☐
  6.5 — Hold a family meeting about Bitcoin holdings (without disclosing exact amounts)

  Convene a family meeting — or individual conversations — with the key people in your succession plan: primary heirs, named trustee, executor, and any family members who will have a role in the estate. Explain that you hold Bitcoin, that it requires a different kind of estate planning, and that there are specific documents and procedures they will need to follow. You do not need to disclose exact amounts. Why it matters: A family that learns about a significant Bitcoin inheritance for the first time while processing a death is a family that is vulnerable to poor decisions. They may not know what questions to ask, may not know who to trust for advice, and may panic-sell immediately — potentially at a price that does not reflect your long-term conviction in the asset. A family that knows Bitcoin is part of the estate before the death event is prepared. They know there is a Letter of Instruction, they know there is a trusted advisor to call, and they have had time to develop basic literacy. The meeting also surfaces any concerns or conflicts that are better addressed while you are alive and can mediate them — not after, when they become legal disputes.

• ☐
  6.6 — Write the Letter of Instruction (location of keys, who to call, step-by-step)

  The Letter of Instruction (LOI) is the operational guide your executor will use to locate and access your Bitcoin. It should be written in plain language, organized by custody type, and include: (a) a complete list of every wallet, exchange, and custody arrangement; (b) the physical location of each hardware wallet; (c) where to find the seed phrase backup for each wallet (reference the location — do not include the seed phrase itself in the LOI); (d) where the hardware wallet PIN is stored; (e) where the passphrase (if any) is stored; (f) where the multisig descriptor file is stored; (g) step-by-step recovery instructions for each wallet type; and (h) contact information for your Bitcoin advisor, estate attorney, and any collaborative custodian. Why it matters: The LOI is the bridge between your legal estate plan (which provides authority) and your technical custody setup (which holds the Bitcoin). Without it, your executor has legal authority to act and no operational ability to do so. The LOI must be updated every time your custody setup changes — a new hardware wallet, a moved exchange account, a new multisig configuration — not just at the annual review. Treat it as a version-controlled document. Date every version. Keep the previous version alongside the new one for reference.

• ☐
  6.7 — Draft a Bitcoin family governance document if multiple family members are involved

  If multiple family members will share governance of a Bitcoin estate — as co-trustees, as LLC members, or as beneficiaries of a trust with discretionary distributions — draft a family governance document that establishes decision-making procedures, voting thresholds for major decisions (large transactions, custody changes, distribution events), and a process for resolving disputes. Why it matters: Family conflict over Bitcoin wealth is one of the leading causes of estate plan failure — not because of legal defects, but because family members disagree on what to do. One heir wants to hold; another wants to sell. One wants to change custody providers; another is comfortable with the current setup. One wants to give Bitcoin to charity; another sees that as a violation of the decedent's intent. A governance document sets the rules for these decisions before the conflict arises — when everyone is still rational and motivated by shared goals rather than grief and competing claims. It also provides the trustee with clear guidance for exercising discretion in situations the trust documents did not anticipate.

• ☐
  6.8 — Identify a professional Bitcoin custody advisor for heirs to contact

  Research and identify at least one professional Bitcoin custody advisor or estate specialist — by name, firm, and contact information — who your heirs can contact immediately after your death for guidance on the technical and operational aspects of accessing your Bitcoin. Include this contact in the Letter of Instruction. Why it matters: Your heirs will be navigating grief, legal paperwork, and a technically complex custody situation simultaneously. Having a pre-identified, trusted professional to call eliminates the search for help at the worst possible moment — and reduces the risk that heirs turn to unqualified advisors, internet forums, or worse, "Bitcoin recovery" scammers who prey on families attempting to access inherited Bitcoin. The advisor should be someone familiar with your specific custody setup (or at least familiar with the type you use), willing to work with estate attorneys and executors, and experienced in Bitcoin inheritance situations. Leave their information prominently in the LOI.

Bitcoin estate planning is not a one-time event. It is a practice. Phase 7 is the annual maintenance checklist — the six tasks that keep your estate plan synchronized with your actual holdings, custody setup, and life situation. Complete these once a year, every year, on a fixed date.

• ☐
  7.1 — Update the inventory for any new wallets or accounts opened

  Review your inventory document (from Phase 1) and add any new wallets, exchanges, or custody arrangements opened since the last review. Remove or archive entries for accounts that have been closed or moved. Update approximate balances if they have changed significantly. Why it matters: The inventory is only as useful as it is accurate. New Bitcoin holders frequently open new wallets or exchange accounts throughout the year — for different purposes, different security levels, or different custody philosophies — and then forget to update their estate plan documentation. An annual inventory review catches these additions before they become undocumented holdings that could be lost. It is also an opportunity to consolidate: if you have wallets with very small, forgotten balances, the annual review is the prompt to sweep those into your primary cold storage and simplify the inventory.

• ☐
  7.2 — Physically verify seed phrase backups are accessible and legible

  Go to each physical location where seed phrase backups are stored and confirm: the backup is where you expect it to be, it is readable (metal engravings are not corroded, paper is not faded or damaged), and the words are complete and in the correct order. Why it matters: Metal seed phrase backups can corrode, particularly if stored in humid environments or near saltwater. Stamp quality varies by product; some stampings become difficult to read over time. Paper backups can fade, get wet, or be destroyed without you realizing it. An annual physical verification confirms your backup infrastructure is intact before it needs to be used. It is also the prompt to replace a backup that has degraded — much less expensive than discovering the degradation when a recovery is being attempted under pressure. Do not skip this step because you assume the backup is fine. Verify it.

• ☐
  7.3 — Review and verify all beneficiary designations

  Log into every Bitcoin IRA, exchange account with beneficiary designation capability, and retirement account, and verify that the primary and contingent beneficiaries listed are current, consistent with your estate plan, and still living. Why it matters: Life changes — marriages, divorces, deaths, estrangements, new children — continuously make previously accurate beneficiary designations incorrect. And because beneficiary designations override your will, an outdated designation can redirect a significant portion of your Bitcoin estate to someone who should not receive it — or to no one (if the named beneficiary is deceased and no contingent is named). The annual verification costs 15 minutes per account and can prevent an outcome that your entire legal estate plan cannot fix. Make it non-negotiable.

• ☐
  7.4 — Update cost basis records for all new purchases

  Add all Bitcoin purchased during the year to your cost basis records: date, USD price at acquisition, quantity, and acquisition platform or method. Reconcile against exchange histories and any on-chain transaction records. Why it matters: Cost basis records must be maintained continuously, not reconstructed retroactively. Exchange records are unreliable over long time periods — platforms change ownership, close, or purge historical records. If you wait five years to reconstruct basis records for five years of purchases, you will find gaps, inconsistencies, and potentially irreconcilable discrepancies. Current-year updates, done annually, keep the record clean and complete. Your tax accountant will thank you. More importantly, your heirs will not face an IRS audit where they must prove a zero-basis assumption is wrong without records to show the original cost.

• ☐
  7.5 — Review gifting strategy in light of current Bitcoin price

  Evaluate whether the annual gift tax exclusion gifting strategy remains appropriate at current Bitcoin price. If Bitcoin has significantly appreciated since last year, more of your estate is now above relevant thresholds — both state and federal. If Bitcoin has declined, you may have opportunities to gift more Bitcoin for the same dollar value of exclusion. Why it matters: Bitcoin's volatility means your estate tax exposure and gifting strategy can change substantially within a single year. A family with $8 million in Bitcoin at the start of the year may have $16 million by December — and may have dramatically underutilized the gifting strategy that would have reduced that exposure. Annual repricing of the gifting strategy ensures you are capturing the highest-value planning windows rather than treating gifting as a fixed annual exercise disconnected from the actual asset value. This review should happen in conversation with your estate planning attorney or advisor, particularly in years with large Bitcoin price movements.

• ☐
  7.6 — Confirm trustee and executor are still willing and able to serve

  Have a brief check-in conversation with your named executor and trustee(s) — confirm they are still willing to serve, still able to serve (health, location, and life circumstances can change), and still have basic familiarity with your custody setup. Why it matters: The person you named as executor five years ago may have moved abroad, developed significant health issues, had a falling-out with the family, or simply decided they no longer want the responsibility. Finding this out before your death — when you can name a replacement — is vastly preferable to finding out after, when the court must appoint a successor. This check-in also serves as a reminder to the named executor that they are in the role, updates them on any changes to the Bitcoin custody setup, and maintains the human relationship that will be critical when the estate plan is actually activated. A 15-minute phone call, once a year, is one of the lowest-cost, highest-value maintenance tasks on this entire checklist.

The 8 Most Common Bitcoin Estate Planning Mistakes

After reviewing dozens of Bitcoin estate plans — and hearing from families who discovered planning gaps at the worst possible time — eight mistakes appear over and over. Each one is avoidable. Each one has cost families real Bitcoin that should have passed to the next generation.

• 1
  Storing seed phrases in a safe deposit box

  Safe deposit boxes seem like an obvious choice — a secure, bank-controlled vault. But they have a critical estate planning flaw: banks can freeze access to safe deposit boxes during probate, and sometimes even before probate is formally opened, depending on state law and bank policy. If your executor cannot access the safe deposit box in the immediate days after your death — and they may not be able to, legally — they cannot access the seed phrase, and they cannot secure or access the Bitcoin during the window when immediate action may be needed (to close Lightning channels, to contact exchanges, to begin the estate claim process). The solution: store seed phrase backups in locations you directly control (a home safe, a fire safe, a trusted family member's home) rather than in bank-controlled storage. Safe deposit boxes can be used for legal documents like wills and trusts — not for operational Bitcoin access documentation.

• 2
  Naming Bitcoin in the will with specific wallet addresses

  A will that says "I leave my Bitcoin wallet address 1A2b3C4d5E6f... to my son" is legally valid but operationally problematic. Bitcoin addresses change with every transaction on non-address-reuse wallets. HD (hierarchical deterministic) wallets generate new addresses for every receive transaction — meaning the address in your will may have a zero balance by the time the will is read. Worse, including specific addresses in a public document (wills are probated publicly in most jurisdictions) reveals your Bitcoin addresses to anyone who searches the probate records — which is a security risk. Reference Bitcoin holdings by general description ("my Bitcoin and other digital assets held in self-custody hardware wallets and exchange accounts, documented in my Letter of Instruction") and let the LOI provide the operational specifics. Keep the will address-free.

• 3
  Assuming exchange custody is automatically estate-plan-ready

  Bitcoin held on an exchange is custodied by the exchange — it requires the exchange's own estate claim process to transfer at death, independent of your will, trust, or other estate documents. This process varies by exchange and can take weeks or months. It typically requires: a certified death certificate, letters testamentary from the probate court naming your executor, a formal written claim, and sometimes a court order (particularly for larger accounts). If you have Bitcoin on an exchange and your estate plan does not explicitly account for the exchange's process — including naming the exchange account in the LOI, documenting the email used to register, and knowing whether the platform has a beneficiary designation option — your executor will face a bureaucratic wall at exactly the moment they need to move quickly. Many families discover, post-death, that a Coinbase or Kraken account holds significant Bitcoin that they had no idea was subject to this process.

• 4
  Forgetting to document the passphrase (25th word)

  If you use a BIP39 passphrase on any wallet, and you do not document it clearly and separately from the seed phrase, you have created a one-way trap. Your heirs will find the seed phrase (correctly). They will restore it on a hardware wallet or software wallet (correctly). They will see a zero balance — and conclude the seed phrase is wrong, the wallet is empty, or the Bitcoin is lost. None of those conclusions are correct: the Bitcoin is sitting in the passphrase-protected wallet, fully intact, permanently inaccessible because one additional piece of information was never documented. This is one of the most emotionally devastating Bitcoin inheritance failures precisely because the recovery feels so close — the seed phrase works, the wallet restores, everything seems fine — until the zero balance appears. Solve this now: confirm whether you use a passphrase, document it clearly and separately, and include a prominent note in the LOI that the passphrase must be entered in addition to the seed phrase to access the correct wallet.

  Not backing up the multisig descriptor file

  Multisig wallets require the descriptor (output descriptor or wallet file) in addition to the threshold number of keys to spend Bitcoin. The descriptor contains the full script configuration — all extended public keys, the threshold, and the script type — that the coordinator software needs to reconstruct the wallet. Without it, the coordinator software cannot find the wallet's addresses on the blockchain, even if all three keys are present and functional. This means that in a 2-of-3 multisig, your heirs could have all three hardware wallets with all three seed phrases, and still be unable to spend the Bitcoin if the descriptor was never backed up. The backup takes two minutes: export the wallet file from Sparrow Wallet, Specter Desktop, or whatever coordinator you use; save it to a USB drive or print a QR code; store it at a separate location from any individual key. Do it now. This is not a "nice to have" — for multisig wallets, it is as critical as the keys themselves.

  Telling too many people about your Bitcoin holdings

  There is an estate planning temptation to be transparent about Bitcoin holdings with family members, advisors, and others involved in your plan. But Bitcoin is a bearer asset — whoever has the keys controls the coins. Disclosing the existence and approximate size of Bitcoin holdings to a wide circle of people increases the risk of targeted theft, social engineering, and coercive attacks. Keep the circle of people who know the approximate scale of your Bitcoin holdings small: your spouse or partner, your estate attorney, your executor, and any co-trustees. The specific key documentation (seed phrases, passphrases, hardware wallet locations) should be known only to the person responsible for maintaining custody — typically you. Everyone else gets the LOI reference point and procedural instructions, not the keys themselves. In your estate plan, separate the authorization chain (who can act) from the access chain (who knows where the keys are) to reduce single points of failure and exposure.

  Waiting until the estate tax exemption changes to act

  The elevated TCJA estate tax exemption is now permanent law under the One Big Beautiful Bill Act of 2025. But permanence is not the same as immutability — future legislation can change it. And state estate taxes operate on a completely different and more volatile schedule. The most common rationalization for inaction: "I'll do this when the rules are clearer." The problem with this approach is that estate planning takes time — attorney consultations, trust formation, beneficiary designation updates, gifting programs — and Bitcoin's appreciation can outpace your planning timeline. A family that waits until the estate tax environment "clarifies" may find that their Bitcoin position has doubled or tripled in the interim, and that strategies which were available when the position was smaller (certain trust structures, GRATs, annual gifting programs) are now less efficient or require larger exemption usage. The best time to plan is now, when the asset value and planning options are both clear. The second-best time is still soon.

  Assuming your attorney understands Bitcoin custody

  Estate planning attorneys are skilled at their domain: wills, trusts, powers of attorney, probate, and tax strategy. Most of them are not skilled at Bitcoin custody — and the ones who are not skilled will not always tell you so. They may draft a trust that grants the trustee authority to hold digital assets without understanding what a hardware wallet is, what a multisig descriptor file is, or why the passphrase documentation is as important as the seed phrase itself. They may advise you to keep your seed phrase "in a safe place" without understanding the specific failure modes of safe deposit boxes for Bitcoin recovery. Before finalizing any legal document that governs your Bitcoin estate, ask your attorney directly: Have you worked with Bitcoin-holding clients before? Do you understand the operational requirements of hardware wallet self-custody? Do you know what a multisig descriptor file is? If the answers are uncertain, supplement the legal work with a Bitcoin-specific advisor who can ensure the operational and legal dimensions of your estate plan align.

Your 2026 Bitcoin Estate Planning Calendar

The seven phases above are timeless — work through them in any year. For 2026 specifically, three forces make the planning calendar more urgent than in prior years: the permanent elevation of the federal estate tax exemption, Bitcoin near all-time highs, and active state estate taxes in more than a dozen states. Here is the 2026-specific quarterly calendar.

• 1
  Update or Create Your Letter of Instruction

  The Letter of Instruction is the single most important document most Bitcoin holders do not have — or have not updated in years. If your custody structure changed at any point in 2024 or 2025 — new hardware wallet, switched exchanges, moved to multisig — your LOI is out of date. Outdated LOIs are not a minor compliance issue; they are a risk that your family never accesses your Bitcoin at all.

  Run an Estate Tax Exposure Calculation at Current Bitcoin Price

  Pull your total Bitcoin holdings and apply the current price. Add other significant assets. Compare the total to relevant estate tax thresholds — federal and your state. If you are above the state threshold or within 20% of it, you are in active planning territory and should schedule an attorney review before mid-year.
• 3
  Review Beneficiary Designations on Exchange Accounts

  Major exchanges — Coinbase, Kraken, Gemini, River, and others — now support beneficiary designations on custodial accounts. These designations are not automatically updated when your will changes or when family circumstances change. A beneficiary designation on file overrides your will. Verify every custodial account in Q1.

  Confirm Your Successor Trustee or Executor Is Still the Right Choice

  People's circumstances change. The friend you named as executor five years ago may have moved abroad, developed health problems, or simply become less reliable. More specifically for Bitcoin: your chosen executor needs to be Bitcoin-literate — comfortable enough with digital assets to follow LOI instructions, interact with a hardware wallet, and coordinate with a custodian without losing the asset.
• 5
  Check Whether Your State's Estate Tax Threshold Has Changed

  Some state estate tax exemptions are indexed to inflation and update annually. Others are fixed by statute. Oregon, Massachusetts, Washington, Illinois, Minnesota, and Rhode Island have lower thresholds that may have pulled your estate into taxable territory without any change in your holdings. Run the numbers with current Bitcoin price.

  Annual Review Meeting With a Bitcoin-Literate Estate Attorney

  Not all estate attorneys understand Bitcoin. A general practitioner may be excellent at trusts and wills but unfamiliar with multisig custody or the mechanics of titling Bitcoin inside an irrevocable trust. Seek advisors who have worked with Bitcoin-holding clients before. At this meeting: review your exposure, discuss lifetime exemption gifts, and update documents that have not been reviewed since 2023 or earlier.
• 2
  Update Your Cost Basis Records

  Bitcoin cost basis is not automatically tracked by any single source of truth. By mid-2026, you should have a clean, reconciled record of every lot. Your tax accountant needs this. Your executor needs this. Your beneficiaries need this. The absence of accurate basis records is one of the most common and costly mistakes in Bitcoin estate administration.
• 3
  Consider Whether Price Appreciation Has Moved You Into a New Planning Tier

  Bitcoin estate planning is tiered. Price appreciation in 2024–2026 may have moved you from one tier to another without any action on your part. The strategies appropriate for each tier differ significantly. Run the numbers again with current price and see which tier you are in — then verify your planning approach matches that tier.

  Heir Education Check: Walk Your Successor Through the LOI

  Walk your primary heir or successor through the LOI — not just "here is where the document is" but actually have them demonstrate they could access your Bitcoin if needed. Where is the hardware wallet? How do they initiate access? Who do they call? A well-designed plan with an untrained executor is a plan that fails at the moment it matters most.
