Crypto Inheritance Planning

Unlike stocks or real estate, cryptocurrency holdings are inaccessible without the private keys. Crypto inheritance planning requires documenting what assets you own, where they are stored, and how heirs can access them—while also considering stepped-up basis rules, estate taxes, and the executor’s ability to liquidate or hold. Without a plan, digital assets are often lost entirely.

The Core Challenge: Private Keys and Account Access

Cryptocurrency is fundamentally different from traditional assets in one respect: whoever controls the private key controls the funds. Unlike a bank account or investment portfolio, there is no institution holding your crypto “in your name.” If you self-custody Bitcoin in a hardware wallet and take the seed phrase to your grave, that Bitcoin is lost forever. There is no legal process to recover it.

This means inheritance depends entirely on how you store your crypto. The method you choose during your lifetime determines whether heirs can recover the assets at all.

Self-Custody Wallets

If you hold crypto in a self-custody wallet (hardware wallet, software wallet, or smart contract), the only way to access the funds is with the private key or seed phrase. You must:

1. Document and store the seed phrase securely. A 12- or 24-word mnemonic is the master key to all funds. Write it down, ideally multiple copies.
2. Decide how to pass it to heirs. Options include:
   • A sealed envelope in a safe deposit box, with instructions to your executor.
   • Shared across multiple trusted people (e.g., three family members each hold one third of words).
   • Stored with a trusted advisor (lawyer, accountant) under sealed instructions to open upon death.
   • In a will or trust, though wills are public and writing seed phrases in unencrypted documents is risky.
3. Make the chain of custody clear. Your executor or heirs must know which wallet the seed phrase opens, where the funds are, and what they should do with the asset (sell, hold, donate).

The security trade-off is acute: the safest way to protect funds from theft during your life (offline, multi-sig, compartmentalized access) can make them impossible for heirs to recover.

Custodied Crypto (Exchanges, Institutions)

If you hold crypto on an exchange (Coinbase, Kraken, etc.) or with a crypto custodian, the institution has a copy of the private key. When you die, the institution can (in theory) transfer or liquidate the holdings if heirs provide the right proof: a death certificate, valid will naming them, and the account’s username or email.

In practice, exchanges are often difficult for heirs to navigate:

• The account may be frozen for security reasons when the institution learns of death.
• Proof of inheritance requirements vary by jurisdiction and institution.
• Withdrawal limits and identity verification can slow the process.
• Small exchanges may go out of business before heirs can claim the funds.

However, exchange holdings are traceable and recoverable by legal heirs, whereas self-custody funds are not. An exchange account is more like a traditional investment account in this respect.

For this reason, some people prefer to hold crypto on reputable exchanges (or with regulated custodians like Fidelity or Coinbase Custody) specifically to simplify inheritance.

Stepped-Up Basis and Tax Treatment

In the United States, inherited assets receive a stepped-up basis to fair market value on the date of death. This is a major tax advantage.

If you bought Bitcoin at $10,000 and it is worth $100,000 when you die, your heirs inherit with a basis of $100,000. If they immediately sell at $100,000, they owe no capital gains tax. The $90,000 appreciation is forgiven entirely.

This rule applies to crypto like any other asset. It means:

The stepped-up basis rule is why many wealthy individuals hold volatile assets until death rather than selling during their lifetime. It is also why documenting holdings is important: tax authorities will want to know the fair market value of crypto at death, which requires records of the holdings at that time.

Note: The stepped-up basis rule is not universal. Some countries (Canada, Australia) do not have stepped-up basis; heirs inherit with the original cost basis and owe tax on gains. Tax treatment varies widely by jurisdiction, so consult a local tax advisor.

Estate Taxes and Valuation

Depending on jurisdiction and the size of your total estate, crypto holdings may be subject to estate tax (also called death tax or inheritance tax).

In the U.S., the federal estate tax applies to estates over ~$13.6 million (2024; adjusted annually). Many states have lower thresholds. The tax is levied on the fair market value of all assets at death, including crypto.

For estate tax purposes, crypto must be valued at fair market value on the date of death. This can be straightforward for Bitcoin or Ethereum (use the price on an exchange that day), but trickier for:

• Illiquid altcoins (what price do you use?).
• DeFi tokens or governance tokens (no central exchange price).
• NFTs (appraisal may be required).

If the estate is large and crypto holdings are significant, the executor may need to hire an appraiser or use exchange data to document valuation. Overstating or understating the value can trigger IRS scrutiny.

Creating an Inventory and Instructions

The first step is practical: document what you own.

Create a list (stored securely) that includes:

• The type of crypto (Bitcoin, Ethereum, altcoins, NFTs, DeFi positions).
• The amount and approximate value.
• Where it is held: exchange name and account (if custodied), wallet name and address (if self-custody), or specific contract/DeFi platform.
• How to access it: username/email, login method, or where the private key/seed phrase is stored.
• Instructions for the executor: should they sell immediately, hold, donate, or liquidate specific amounts to pay estate taxes?

Include the names of people (executor, heirs, advisors) and their contact information. Avoid writing private keys directly in the document; instead, reference a separately stored envelope or location (“The seed phrase for my Ledger is in the safe deposit box at [bank name], key held by [person]”).

This inventory should be:

• Stored in a secure location (safe deposit box, lawyer’s office).
• Updated regularly as your holdings change.
• Included in your will or trust, or referenced in a separate letter of instruction to your executor.

Executor and Legal Considerations

Your executor (the person who manages your estate) needs clear authority and guidance to handle crypto:

• Give explicit permission in your will or trust for the executor to access, liquidate, and distribute crypto holdings.
• Name a crypto-literate trustee or advisor if your executor is unfamiliar with digital assets.
• Simplify the process by holding crypto in custodied accounts (exchanges, Fidelity, etc.) rather than self-custody if possible. This makes recovery easier.
• Consider a revocable living trust instead of a will for very large holdings. Trusts are private, do not require probate, and give your named trustee clear access to assets immediately.

For DeFi positions or complex smart contracts, the executor may need help from a crypto professional to understand what assets exist and how to liquidate them.

International and Jurisdictional Variations

Crypto inheritance law and tax treatment vary significantly by country:

• Canada: No stepped-up basis; capital gains are triggered at death; 50% of gains are taxable.
• UK: Assets receive a stepped-up basis to probate value; inheritance tax may apply if the estate exceeds thresholds.
• Australia: Crypto is taxed as a capital asset; gains are taxable; no stepped-up basis (CGT event occurs at death).
• EU: Inheritance law varies by member state; some countries recognize digital assets in probate, others do not.

If you are a resident or citizen of multiple countries, or if your heirs are overseas, consult an international tax and estate attorney.

Digital Legacy and Recovery

Beyond the financial aspects, consider:

• Recovery of accounts: Document not just crypto, but email addresses, two-factor authentication (2FA) methods, and any recovery codes. If the executor cannot access the exchange account email, recovery may be impossible.
• Lost-and-found: If you hold coins on a deprecated exchange or in a wallet you no longer use, ensure that information is recorded. Old exchange accounts often vanish or get frozen.
• Donations or charitable giving: If you wish to donate crypto to a charity, specify the instructions clearly and ensure the charity has a secure wallet address.
