How to Inherit Bitcoin: A Step-by-Step Guide for Heirs

You've just learned that someone you loved held Bitcoin. Now you're responsible for it. Maybe you found a hardware wallet in a drawer. Maybe you know there's an exchange account somewhere. Maybe you have no idea where to start.

This guide is written specifically for heirs — people who have inherited Bitcoin or are helping a family navigate a Bitcoin estate. It covers everything from the immediate steps right after death to the legal requirements, tax implications, and what to do when Bitcoin seems lost.

The most common Bitcoin inheritance mistake isn't a wrong password — it's acting too fast without the right information. Take a breath. Nothing needs to happen in the first 24 hours.

1. Immediate Steps When a Bitcoin Holder Dies

The period immediately after a loved one's death is not the time to start guessing passwords or moving Bitcoin. Mistakes made in the first few days can be permanent and irreversible.

2. If There Is a Letter of Instruction (LOI)

A Bitcoin Letter of Instruction is a gift from the deceased. If one exists, the process is structured — follow it carefully.

Step 1: Find and secure the hardware wallet

The LOI should tell you where the hardware wallet is stored. Common locations include home safes, safety deposit boxes, or with a trusted attorney. Once found, do not connect it to any computer until you've read the full LOI and understand the process.

Step 2: Find the seed phrase backup

The seed phrase (12 or 24 words) is the master key. It should be stored separately from the hardware wallet — often on steel plates, in a separate location from the device. The LOI will specify where. This is the most important document in the estate for Bitcoin access.

Step 3: Identify the software

The LOI should specify what wallet software was used (Electrum, Sparrow, Bitcoin Core, Specter, etc.) and what type of wallet (standard, multisig, hardware wallet brand and model). This matters for recovery procedures.

Step 4: Contact exchanges

If the deceased held Bitcoin on exchanges (Coinbase, Kraken, Gemini), the LOI should list the accounts. Contact each exchange with a death certificate and begin their inheritance process (detailed below).

3. If There Is No Letter of Instruction

The harder case. No LOI means detective work. Start here:

Self-custody recovery

Search for hardware wallet devices (Trezor, Ledger, Coldcard, Foundation, BitBox are most common), USB drives that might contain wallet software, paper backups (metal plates, laminated cards, any list of 12 or 24 English words), and encrypted files on computers named things like "wallet," "backup," or "keys."

If you find a hardware wallet but no PIN or seed phrase, you have limited options. With the seed phrase, you can restore the wallet to a new device regardless of what happens with the PIN. Without the seed phrase and without the PIN — professional key recovery services may help, but success is not guaranteed.

Exchange account recovery (without LOI)

Search email accounts for correspondence from Coinbase, Kraken, Gemini, River, Swan, Bitfinex, or other exchanges. Bank statements showing ACH transfers to exchange companies are another indicator. Once identified, contact the exchange's inheritance/bereavement team directly.

Coinbase: Has a dedicated Digital Asset Inheritance form. Requires death certificate, Letters Testamentary or Letters of Administration from probate court, and government-issued ID for the heir.

Kraken: Requires contacting support and providing a death certificate, proof of legal authority (Letters Testamentary or equivalent), and government ID.

Gemini: Has an Estate Services team. Requires death certificate, Letters Testamentary, and government ID. May require additional documentation for large accounts.

4. Proving Your Right to Inherit

Whether you're recovering self-custody Bitcoin or claiming exchange accounts, you need to establish legal authority. This is not optional — exchanges will not release funds without it, and attempting to move self-custody Bitcoin before establishing legal authority can complicate the estate.

Letters Testamentary (probate estate)

If the deceased had a will, the probate court will appoint an executor and issue Letters Testamentary — the document that proves the executor has legal authority to administer the estate. This is the primary document exchanges require.

Letters of Administration (no will)

If there was no will (intestate), the probate court issues Letters of Administration to an administrator. Same authority, different name.

Trust authority (trust-based estate)

If Bitcoin was held in a trust, the trustee already has authority under the trust document. No probate required. The successor trustee named in the trust document takes over upon the grantor's death.

5. Hardware Wallet Inheritance: Critical Traps

Hardware wallets have specific security behaviors that can permanently destroy access if you don't know about them.

Coldcard: The PIN trap

Coldcard devices have a duress PIN — a second PIN that appears to unlock the device but instead silently wipes it or shows a decoy wallet. If you find a Coldcard and a PIN that was supposed to be the "main" PIN, confirm with the estate attorney or any other documentation whether there are multiple PINs before attempting anything. Three wrong PIN attempts on a Coldcard triggers a complete wipe.

Trezor: The passphrase / 25th word trap

Trezor devices (and many others) support an optional 25th word — a passphrase added to the standard 24-word seed. This creates an entirely separate wallet hidden behind the passphrase. If someone used a Trezor with a passphrase and you recover the 24-word seed but not the passphrase, you can restore the seed to a device but will see a wallet with zero balance (the real wallet is behind the passphrase). The 25th word must be recovered separately. Check the LOI, personal documents, and password managers.

Ledger: PIN wipe protection

Ledger devices wipe after three incorrect PIN attempts. If you find a Ledger and don't have the PIN, do not guess. Use the seed phrase to restore to a new device instead. The seed phrase, not the device, is the actual key.

6. Exchange Account Inheritance: What Documents You Need

Every major exchange has an inheritance/bereavement process. None of them are fast, but all of them are navigable with the right documentation. Expect the process to take 2–8 weeks.

Standard documentation required by most exchanges:

• Certified death certificate — the official government-issued version, not a photocopy
• Letters Testamentary or Letters of Administration — from the probate court
• Government-issued ID for the claimant (executor or administrator)
• Court order (sometimes required for large accounts or when there are disputes)
• Proof of relationship to the deceased (sometimes)

Some exchanges will transfer assets to a new account in the heir's name; others will liquidate and send fiat. Ask explicitly which process they follow — the tax implications differ significantly (see below).

7. Tax Considerations for the Heir

Inheriting Bitcoin has different tax treatment than receiving it as a gift or buying it yourself. Understanding this upfront prevents costly mistakes.

Step-up in basis

This is the most important tax concept for Bitcoin heirs. When you inherit Bitcoin, your cost basis is stepped up to the fair market value on the date of death — not what the deceased paid for it.

Example: Your parent bought Bitcoin at $5,000. It's worth $90,000 at their death. You inherit it. Your cost basis is $90,000. If you sell it tomorrow at $92,000, you owe tax on $2,000 in gains — not on $87,000. The $85,000 gain that occurred during the deceased's lifetime is completely forgiven for income tax purposes.

This step-up is one of the most powerful wealth-transfer benefits in the tax code, and it applies fully to Bitcoin.

What to document

• The Bitcoin price on the date of death (CoinMarketCap historical data works; a CPA may want a more formal source)
• The quantity inherited (down to the satoshi)
• Any exchange transfers or sales, with dates and prices

Reporting requirements

Bitcoin itself is not "cash" under IRS reporting rules, so there's no automatic requirement to report receiving it regardless of amount. However, if you sell Bitcoin and the proceeds exceed certain Bitcoin family office minimum requirementss, you'll receive a 1099-DA from exchanges (beginning in 2025). If you inherited a substantial amount, consult a CPA who specializes in digital assets before making any moves.

8. What to Do if Bitcoin Appears Lost

Sometimes you know Bitcoin existed but can't find any of the keys or access credentials. This is common — and sometimes recoverable.

Blockchain forensics

If you know a wallet address (perhaps from an exchange withdrawal history or an old email), a blockchain forensics service can confirm the current balance and help trace the transaction history. This won't recover access, but it confirms what you're looking for.

Key recovery services

Legitimate key recovery services exist for specific scenarios — a partially damaged seed phrase backup, a forgotten passphrase you can partially remember, or a corrupted wallet file. These services work with what you have; they cannot create keys from nothing.

Professional estate recovery

If the estate is large and the Bitcoin appears inaccessible, consider engaging a professional digital asset estate recovery firm. They can conduct a thorough search of digital devices, cloud accounts, email archives, and financial records to find evidence of access credentials.

9. Professional Help and Next Steps

Bitcoin inheritance is complex enough that professional guidance is worth it for any significant amount. The right team includes a Bitcoin estate attorney (not a general estate attorney who "handles crypto"), a CPA with digital asset experience, and potentially a digital asset custodian if ongoing management is needed.
