Crypto inheritance planning works only when two things are in place: a will or trust that treats your digital assets like the property they legally are, and a separate set of instructions that gives your heirs the private keys, seed phrases, PINs, and two-factor backup codes they need to reach the funds. Skip the second part and your heirs may inherit the legal right to coins they can never touch.
Why Crypto Breaks the Usual Inheritance Playbook
The IRS treats virtual currency as property, not currency.1Internal Revenue Service. Digital Assets That puts a Bitcoin balance, an Ethereum position, or tokens in a hardware wallet into the same estate as stocks and real estate. Federal law defines the gross estate as everything the decedent had an interest in at death, tangible or intangible.2Office of the Law Revision Counsel. 26 USC 2031 – Gross Estate Your executor has a legal duty to find, value, and account for all of it.
The difference from other property is technical, not legal. A house passes by deed, a brokerage account by beneficiary form or probate, and both remain reachable through the institution that holds them. Crypto held in self-custody has no institution. If nobody knows the seed phrase, no court order can extract those funds from the blockchain. Hardware security keys and modern authentication are built specifically to resist bypass. There is no “forgot password” reset for a hardware wallet without a recovery phrase.
What the Law Can and Can’t Do
Executors and trustees get authority over digital accounts through the Revised Uniform Fiduciary Access to Digital Assets Act (RUFADAA), which nearly every state has adopted in some form. RUFADAA lets a fiduciary demand access from a service provider as part of estate administration. Without it, exchanges could hide behind their privacy policies.
But RUFADAA has a hierarchy that surprises people. Any online tool the platform offers for naming who gets access after death overrides your will. If you never used that tool and never addressed digital assets in your estate documents, the platform’s terms of service control, and many of those terms restrict disclosure. Even at its best, RUFADAA gets your executor as far as the exchange’s front door. It does nothing for a self-custody wallet, because there is no company to serve with legal papers.
Intestacy has the same limit. If you die without a will, your state decides who inherits your personal property, usually a spouse, then children, then more distant relatives. The right to inherit is not the problem. Inheriting crypto you cannot access is meaningless.
Step One: Inventory Every Holding
Start with a complete list of every place your crypto lives. Hot wallets connected to the internet, cold wallets on hardware devices, exchange accounts, staking positions, and tokens held in decentralized finance protocols all need to be documented. For each, record the platform or device name, the public wallet addresses so heirs can verify the funds exist, and the approximate value.
Update the inventory at least annually, or whenever holdings change meaningfully. Crypto owners tend to accumulate accounts across platforms over time, and a two-year-old list can be missing half the estate’s value.
Step Two: Write a Letter of Instruction
The technical roadmap belongs in a separate document, not the will. Wills become public during probate, and anyone who reads a seed phrase in a public filing controls the funds. A letter of instruction sits outside probate, stays private, and gives your heirs what they need to actually move coins.
A workable letter covers:
- Seed phrases: the twelve or twenty-four-word recovery sequences for each wallet.
- PINs and passwords: device PINs for hardware wallets, account passwords for exchanges.
- Two-factor authentication details: backup codes for authenticator apps, the location of any hardware security keys, and recovery keys for accounts using advanced protection.
- Physical locations: where hardware wallets, encrypted USB drives, and paper backups are stored.
- Step-by-step instructions: for heirs who are not technical, plain directions on how to connect a hardware wallet, enter a recovery phrase, and transfer funds to a new wallet.
Store the letter in a fireproof safe, a bank safe deposit box, or with a trusted attorney. Some owners split the material, keeping the seed phrase in one location and the instructions for using it in another, so a single break-in does not compromise everything.
Don’t Overlook Two-Factor Authentication
Two-factor authentication is one of the most common places crypto inheritance stalls. If an exchange account requires a code from a phone app or a hardware key, an heir without that device faces a lengthy recovery process. Some platforms require court orders and months of correspondence before they will bypass authentication for an estate claim.
Identify which method protects each account, where the backup codes are, and whether you set up any legacy contact or account recovery option through the platform itself. Backup codes rotate or expire on some services, so this section of the letter needs periodic review.
What Heirs Face at an Exchange
Most major exchanges do not offer beneficiary designations or transfer-on-death features. Coinbase states that naming a beneficiary within the account is not currently possible.3Coinbase. Claim a Decedents Coinbase Account That is the industry standard. Estate documents or state intestacy rules determine who receives the account, and the exchange transfers ownership only after verifying legal paperwork such as a death certificate and letters testamentary, letters of administration, or a small estate affidavit. Kraken uses a similar process, requiring a color image of the death certificate and legal proof of the claimant’s role as estate representative.4Kraken. Deceased Client Account Claims Verification can take weeks.
The practical result: exchange-held crypto almost always passes through probate. Plan on your heirs needing a court-appointed representative with formal authority before anyone can move funds.
What Heirs Face With Self-Custodied Crypto
For crypto held in a hardware or software wallet under your direct control, there is no company to petition. The executor needs the physical device or the recovery seed phrase, and ideally both. With the seed phrase, the executor enters the words into a compatible wallet application to restore access to the private keys, then transfers the funds to an estate wallet or directly to beneficiaries. Every transfer should be documented with transaction hashes and screenshots for the probate accounting.
A single typo in a destination address can send funds to an unrecoverable location. No bank reverses this. Executors unfamiliar with crypto should consider hiring a specialist or working alongside an heir who understands the technology rather than attempting transfers alone.
The Tax Picture Your Plan Should Anticipate
Stepped-Up Basis
Inherited cryptocurrency receives a stepped-up basis. The heir’s cost basis resets to the fair market value on the date the owner died, regardless of the original purchase price.5Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent Bitcoin bought for $500 and worth $60,000 on the date of death carries a $60,000 basis for the heir. All the growth during the owner’s lifetime escapes income tax.
Inherited property is also treated as held for more than one year, no matter how recently the owner died.6Office of the Law Revision Counsel. 26 USC 1223 – Holding Period of Property An heir who sells a week after inheriting still pays long-term capital gains rates.
Documenting the date-of-death value is critical. The IRS accepts values calculated at a specific date and time, typically using data from the exchange or pricing index where the asset trades.7Internal Revenue Service. Frequently Asked Questions on Virtual Currency Transactions If your heir cannot document that number later, the IRS could apply a zero basis and tax the entire eventual sale price.
Estate Tax
The federal estate tax basic exclusion amount for 2026 is $15,000,000 per person.8Internal Revenue Service. Whats New – Estate and Gift Tax Estates below that threshold owe no federal estate tax and do not need to file Form 706. Estates above it must report the full value of all assets, crypto included, on Form 706.9Internal Revenue Service. Instructions for Form 706 The $15,000,000 figure was set by legislation signed in 2025 and will be adjusted for inflation.10Office of the Law Revision Counsel. 26 USC 2010 – Unified Credit Against Estate Tax
Even estates that fall well under the exemption still need accurate date-of-death valuations for the stepped-up basis calculation. Zero estate tax owed and precise valuations for the heir’s future capital gains are separate questions.
Foreign Exchange Accounts
Crypto on non-U.S. exchanges can trigger reporting obligations that catch executors off guard. Under current FinCEN guidance, a foreign account holding only virtual currency is not a reportable account for FBAR purposes.11Financial Crimes Enforcement Network. FinCEN Notice 2020-2 – Virtual Currency Reporting on the FBAR If the account also holds traditional currency or securities, the whole account falls under FBAR rules once the aggregate value of all foreign financial accounts tops $10,000 at any point in the year. FinCEN has said it intends to expand these rules to crypto-only accounts, and many tax professionals report anyway as a precaution.
Form 8938 reaches further. Unmarried filers must report specified foreign financial assets exceeding $50,000 at year-end or $75,000 at any point during the year; joint filers face $100,000 and $150,000 thresholds.12Internal Revenue Service. Do I Need to File Form 8938 Statement of Specified Foreign Financial Assets The IRS has indicated digital assets on non-U.S. exchanges can count. An executor should check whether these thresholds were crossed during the decedent’s final tax year and during estate administration.
Smart-Contract Tools Are Supplements, Not Replacements
Two on-chain approaches to inheritance are worth knowing about but not relying on alone. A dead man’s switch smart contract releases funds to a designated wallet unless the owner checks in within a set window. The idea works; the risks are real, since a hospitalization or long trip can trigger a false release, and smart contract bugs have caused losses in other contexts. Social recovery wallets replace a single seed phrase with a group of trusted guardians who can collectively authorize a new key, typically with a time lock so the legitimate owner can cancel an unauthorized attempt. Both are niche today and require specific wallet types.
Neither eliminates the need for a will, a letter of instruction, and tax planning. An heir relying solely on a smart-contract mechanism, with no legal documentation behind it, can struggle to prove ownership to a probate court or the IRS.
