Your will doesn't control who gets your Bitcoin IRA. Your beneficiary designation does — and it overrides your will entirely. Name the wrong beneficiary and your heirs face probate, a compressed 5-year distribution window, or a massive unexpected tax bill. This guide covers every scenario: exchange accounts, Bitcoin IRAs, self-custody wallets, and when a trust is the right choice.
A beneficiary designation on a Bitcoin IRA, exchange account, or TOD registration overrides your will completely. If your will leaves everything to your spouse, but your Bitcoin IRA still names your college girlfriend as beneficiary from 2015, she gets the IRA. The will is irrelevant. Check your designations today.
Traditional estate planning — a will, maybe a revocable trust — is built around assets that have clear ownership records, custodians with established inheritance procedures, and no custody risk at transfer. Bitcoin breaks all three assumptions.
Bitcoin can be held in at least five different ways, and each has completely different inheritance mechanics:
| How Bitcoin Is Held | How It Passes at Death | Beneficiary Designation? | Goes Through Probate? |
|---|---|---|---|
| Bitcoin IRA (traditional or Roth) | Beneficiary designation — overrides will | Yes — critical to get right | No — if designation is valid |
| Exchange account with TOD (Coinbase, etc.) | Transfer on Death registration | Yes — varies by exchange | No |
| Exchange account without TOD | Through estate/probate | No | Yes — unless in a trust |
| Self-custody (hardware wallet / seed phrase) | Only if heirs know it exists and can access it | None | Varies — can be probate or trust |
| LLC or trust | Passes per operating agreement / trust terms | Governed by entity documents | No — if properly structured |
Each category requires different planning. The most expensive mistakes happen when people apply the wrong framework — treating a Bitcoin IRA like self-custody, or assuming a will covers exchange accounts when it doesn't.
If you hold Bitcoin in a self-directed IRA, your beneficiary designation is the single most important document in your estate plan. Get it wrong and you could cost your heirs hundreds of thousands of dollars in avoidable taxes.
Naming your estate as IRA beneficiary is almost always catastrophic. The consequences:
For married Bitcoin holders, naming your spouse as primary IRA beneficiary preserves the most valuable option in inherited IRA planning: the spousal rollover.
A surviving spouse who inherits an IRA can roll it into their own IRA — treating it as if it were always theirs. The advantages:
The spousal rollover is only available when the spouse is named directly as beneficiary on the IRA form — not when the IRA passes through a will or trust (unless the trust meets specific look-through requirements allowing the spouse to elect rollover treatment).
Under the SECURE Act (2020) and SECURE 2.0 (2022), most non-spouse beneficiaries must withdraw the entire inherited IRA within 10 years of the original owner's death. Additionally, if the original owner had already begun required minimum distributions (RMDs — reached age 73), the heir must also take annual RMDs during the 10-year window.
For a Bitcoin IRA that has appreciated significantly, this creates a compressed ordinary income tax problem. A $1M Bitcoin IRA distributed over 10 years to a beneficiary earning $300K/year adds $100K/year in ordinary income — potentially pushing the marginal rate to 37% on every dollar of IRA distribution.
Planning implication: for non-spouse heirs, consider a Roth conversion strategy during your lifetime to convert Bitcoin IRA assets to Roth IRA. The heir inherits a Roth — still subject to the 10-year rule, but all distributions are completely tax-free.
Five categories of heirs are "Eligible Designated Beneficiaries" with more favorable treatment:
| EDB Category | Distribution Rules | Key Consideration |
|---|---|---|
| Surviving spouse | Spousal rollover OR life expectancy stretch | Rollover is almost always superior |
| Minor child of account owner | Life expectancy until age 21, then 10-year rule | Only works for owner's own minor children — not grandchildren |
| Disabled individual (IRC §72(m)(7)) | Life expectancy stretch | IRS definition of disabled is strict |
| Chronically ill individual | Life expectancy stretch | Annual certification may be required |
| Individual not more than 10 years younger than owner | Life expectancy stretch | Useful for naming a sibling close in age |
When you name multiple beneficiaries or when a beneficiary predeceases you, the distribution method matters enormously.
Per stirpes ("by the branch"): If a named beneficiary dies before you, their share passes to their descendants. Example: you name three children equally. One child predeceases you. Under per stirpes, the deceased child's share passes to their children (your grandchildren) — keeping the inheritance within that family branch.
Per capita ("by the head"): If a named beneficiary predeceases you, their share is divided equally among the surviving beneficiaries. The deceased child's family branch receives nothing.
For most families, per stirpes is the correct choice — it ensures that your Bitcoin IRA reaches the right family branches even if a beneficiary predeceases you. But the default on most IRA custodian forms is per capita. You must affirmatively elect per stirpes, or your intent may not be honored.
Sometimes the right answer is to name a trust as the IRA beneficiary rather than an individual. This is appropriate when:
However, naming a trust as IRA beneficiary creates significant complexity. The IRS imposes strict requirements for a trust to qualify as a "see-through" or "look-through" trust that inherits the same distribution rules as an individual beneficiary:
Conduit trust: All IRA distributions must be passed through immediately to the beneficiary. This "counts" the beneficiary's age for the 10-year rule. Simple and clean, but doesn't allow the trustee to accumulate distributions inside the trust.
Accumulation trust: IRA distributions can be accumulated inside the trust rather than passed through immediately. More flexible, but uses the oldest trust beneficiary's age for distribution calculations — which may not be favorable. The trust also pays income tax at compressed trust rates on accumulated IRA income (37% at just $15,650 of trust income in 2026).
The intersection of SECURE Act rules, see-through trust requirements, conduit vs. accumulation structure, and state trust law is one of the most technically complex areas of estate planning. An IRA beneficiary trust drafted incorrectly — even slightly — can fail the look-through test, resulting in your heirs losing access to the 10-year stretch and being forced to distribute the entire balance within 5 years. Engage an estate planning attorney who has specifically drafted SECURE Act-compliant IRA beneficiary trusts.
Exchange accounts are more varied than IRAs. Some offer Transfer on Death (TOD) registration; most do not. The state of play:
Coinbase: As of 2024–2025, Coinbase has implemented beneficiary designation features for individual accounts in most US states. You can name a primary and contingent beneficiary. At death, the beneficiary must contact Coinbase with a death certificate and ID. The process is custodian-specific and subject to change — verify current availability and requirements directly with Coinbase.
Most other major exchanges (Kraken, Gemini, Binance.US, Bitstamp): Generally do not offer formal TOD designations. Bitcoin in these accounts passes through your estate — meaning probate if not held in a trust.
Option 1: Hold in a revocable living trust. If your exchange account is held in the name of your revocable trust (or transferred to the trust per the trust's pour-over provisions), it passes directly to trust beneficiaries without probate. The trust acts as the "beneficiary designation" — your trustee administers the account per the trust terms.
Option 2: Move to self-custody and plan for access. Most long-term Bitcoin holders keep large positions in self-custody anyway. Planning for self-custody inheritance (discussed below) is often cleaner than relying on exchange TOD features that may change.
Bitcoin held in self-custody — hardware wallets, paper wallets, seed phrases, multisignature setups — has no built-in inheritance mechanism. The Bitcoin belongs to whoever controls the private keys. If no one knows the keys exist or where they are, the Bitcoin is gone forever.
Estimated lost Bitcoin from inaccessible wallets runs in the millions of coins. Most of this loss is accidental — the holder died without sharing access information, assuming they'd deal with it later.
The fundamental tension in Bitcoin inheritance planning: the seed phrase that controls your Bitcoin must be both secured (so no one steals it while you're alive) and accessible (so your heirs can recover it when you're gone). Standard approaches:
The simplest approach for modest Bitcoin holdings:
Critical caution: Never put the seed phrase in your will. Wills become public records in probate — your seed phrase would be visible to anyone who pulls the probate file.
For significant Bitcoin holdings, a multisignature setup (e.g., 2-of-3 or 3-of-5) distributes the custody risk. Your heirs must collect a threshold number of key shards from different locations or trustees to access the Bitcoin. This eliminates single points of failure and prevents any one person from accessing the Bitcoin alone.
Unchained Capital and Casa offer collaborative multisignature custody solutions with explicit inheritance protocols — your designated heirs can recover Bitcoin through a defined process even without your participation.
Placing self-custody Bitcoin in a dynasty trust or revocable living trust is the cleanest long-term solution. The trustee holds the keys (or directs a custodian), and the trust's succession provisions automatically govern Bitcoin distribution when you die. No probate, no seed-phrase scramble, no relying on a letter that might not be found. The trust also provides creditor protection and estate tax planning benefits that no letter of instruction provides.
Beneficiary designation errors accumulate silently over time. The most common scenario: a designation set 10 years ago is now completely wrong due to changed circumstances. Required review triggers:
| Life Event | Required Action | Risk If Not Updated |
|---|---|---|
| Marriage | Update IRA to add or designate spouse as primary | Spouse may not inherit IRA; loses spousal rollover |
| Divorce | Remove ex-spouse immediately from ALL designations | Ex-spouse inherits IRA regardless of divorce decree |
| Birth of child | Add child as contingent beneficiary; consider trust if minor | Child inherits nothing if primary predeceases you |
| Death of named beneficiary | Name a new beneficiary immediately | Passes to estate if no contingent named |
| Major Bitcoin appreciation | Review whether individual vs. trust designation is still optimal | Large IRA may benefit from trust structure for creditor/tax reasons |
| SECURE Act / tax law changes | Review IRA beneficiary trust documents for compliance | Non-compliant trust loses look-through status |
This deserves special emphasis: in most states, divorce does NOT automatically revoke a beneficiary designation. Your Bitcoin IRA, 401(k), and life insurance all remain payable to your ex-spouse unless you affirmatively update the form. The divorce decree says nothing — the custodian follows the designation on file. Courts have repeatedly upheld this rule even when the divorce decree explicitly assigned retirement accounts to the divorced spouse. Update all beneficiary designations the day your divorce is finalized, or as soon as legally possible.
Beneficiary planning preserves what you've built. Mining builds it faster — with major tax deductions including bonus depreciation, OpEx write-offs, and capital asset conversion. The strongest Bitcoin family offices combine both.

Nothing in this guide constitutes legal or tax advice. Engage an estate planning attorney to review your specific beneficiary designations and self-custody access plan.
Bitcoin in an IRA passes by beneficiary designation — not your will — and that designation overrides your will entirely. Bitcoin on exchanges varies by platform; most don't offer TOD. Self-custody Bitcoin has no designation at all. Each category requires specific planning: IRA designation form, exchange TOD or trust, and an inheritance letter plus proper access protocol for self-custody.
Almost never. It forces probate, eliminates the spousal rollover, and may compress the distribution window to 5 years instead of 10 — dramatically accelerating your heirs' tax bill. Always name an individual or a properly drafted see-through trust.
Yes, if the trust meets IRS look-through requirements: irrevocable at death, identifiable human beneficiaries, copy provided to custodian by October 31 of the year after death, and either conduit or accumulation trust structure. This requires an estate planning attorney experienced with SECURE Act-compliant IRA beneficiary trusts — a generic revocable trust likely won't qualify.
Only if your heirs know the Bitcoin exists, know where the seed phrase is, and know how to use it. If none of those are true, the Bitcoin is effectively lost permanently. The minimum required: a letter of instruction with your executor, stored separately from your will (which is a public record in probate). The best solution is Bitcoin held inside a trust with a professional trustee who has custody access.
