Crypto Estate Planning

Crypto estate planning is the part of an estate plan that makes it possible for a fiduciary or a beneficiary to reach cryptocurrency after the owner's death or incapacity. It is worth separating from digital estate planning, which is the neighboring subject of getting into online accounts, and which the digital estate planning page covers along with the uniform act that governs it. That page draws the line itself, noting that a brokerage account is not a digital record while the login to it is, and that crypto is the case where the asset and the record are the same thing.

That identity is the whole difficulty. With a brokerage account, a bank account or a house, the property exists independently of any credential, so a fiduciary who proves their appointment can compel the institution holding it to act. With crypto held in self-custody there is no institution to compel. The ledger will move the asset for whoever can produce a valid signature and for nobody else, and a private key cannot be reissued, subpoenaed or reconstructed. So the planning problem is not primarily legal. It is the problem of getting a secret to the right person at the right time without exposing it while the owner is alive.

The first thing to establish is where the asset actually sits, because the two cases behave differently and most people have both. Crypto held with a trading platform or a custodian is, from the fiduciary's point of view, an account: there is a company with records, a legal obligation to the customer and a process for a deceased account holder, and the fiduciary's task is the familiar one of proving who they are. What that process requires and how long it takes are set by the platform. Crypto in self-custody has no such counterparty. Whoever holds the key controls the asset, which is the point of self-custody and the reason it creates an estate problem the owner has to solve personally.

The mechanics that address it share one design principle: separate the information from the authority. The estate documents can say who is entitled to the crypto and who is to administer it, and they should, because that is what makes a fiduciary's claim on a platform work and what tells a family the asset exists at all. The means of access travels by a different route. In practice that means three things kept apart from each other. First, an inventory that says what exists, on which networks, and where the means of access is held, without containing the means of access itself; a fiduciary who does not know an asset exists cannot look for it, and there is no statement in the mail. Second, arrangements that avoid concentrating the whole asset in a single document, including multi-signature arrangements, where more than one key is required to authorize a transfer and different keys are held by different people, and split-secret arrangements, where a single secret is divided into parts that are individually useless. Third, for platform-held crypto, using whatever the platform itself offers for a deceased account holder, and reading what it requires before it is needed.

What must not happen is putting the key in the will. A will admitted to probate generally becomes a public record, which makes a will a document designed to be read by strangers, and the same objection applies to anything else filed with a court. This is the point at which the general answer runs out and a specific arrangement has to be designed for the person, their family and the size of the holding, which is a genuine reason to work with a lawyer who has done it before rather than adapt a template.

The two tax facts at death. The first is inclusion. Crypto is part of the taxable estate: the Instructions for Form 706 list digital assets among the items to be included in the gross estate, direct that they be reported on Schedule F, define them as "any digital representations of value that are recorded on a cryptographically secured distributed ledger or any similar technology", give non-fungible tokens, cryptocurrencies and stablecoins as examples, and state that if an asset "has the characteristics of a digital asset, it will be treated as a digital asset for federal transfer tax purposes". Whether a return is required at all depends on the estate's total size against the filing threshold, which is a general estate-tax question and not a crypto question.

The second is basis. Because federal tax law treats crypto as property rather than currency, the ordinary rule for property acquired from a decedent applies: basis is determined by reference to value at death rather than by what the decedent paid. The mechanics, including the exceptions and the community property variation, are on the step-up in basis page and are not restated here. The consequence specific to crypto is worth naming, though, because it cuts against the folklore that crypto records are impossible to reconstruct: an asset bought years ago at a fraction of its later value, whose purchase records are long gone, is measured for the heir from its value at death, so the missing purchase history stops mattering at that point. A sale during life would have required it.

A blunt closing point about valuation and access. The tax rules value the asset; they do not deliver the key. An heir can be handed a fair market value, a Schedule F entry and a basis figure for a holding that nobody can move.

A workable arrangement is built in five steps, in this order. Inventory what exists, network by network, separating platform-held holdings from self-custodied ones. Decide who receives each holding and who administers it, and put that in the will or trust, where it belongs. Design the access route separately, so that no single document a court will read contains the means of access, and so that the loss of one person or one location does not lose the asset. Write down the instructions the fiduciary will need, in plain terms, including which networks are involved and what software will be required. Then review it: a new wallet, a moved device or a changed arrangement makes the previous plan wrong, and wrong is worse than absent.

A hypothetical, with round numbers, showing what the tax rules do and do not solve. Marisol bought 2 units of a coin years ago for a total she can no longer document. She dies holding them in self-custody, and on her date of death they are worth $42,000 each, so $84,000 goes into her gross estate and is reported on Schedule F. Her son's basis is determined from that date-of-death value rather than from her purchase price, so when he sells for $92,000 his gain is $92,000 minus $84,000, or $8,000, and the undocumented purchase price never enters the calculation. Now change one fact and nothing else: if the key cannot be found, every one of those figures still describes an asset her son cannot move. The tax analysis and the recovery problem are independent, and only one of them can be fixed after the fact.

Pros

• The problem is solvable in advance and almost never solvable afterwards, which makes planning here unusually high-value relative to the effort.
• Multi-signature and split-secret arrangements let an owner separate the authority to act from any single document or person, which no ordinary asset requires and no ordinary estate plan provides.
• Because the general basis rule at death applies, an heir's cost basis is measured from value at death, so an incomplete purchase history stops mattering at that point.
• Platform-held crypto inherits an ordinary account process, so a holder who wants simplicity for a fiduciary has a route to it.

Cons

• A lost key is generally final. There is no institution with a duplicate, no reset process, and no court order that recovers it.
• Every mechanism that makes access possible for a fiduciary also makes theft possible for whoever finds it, so the plan has a security cost that runs for the owner's whole life.
• The arrangements that manage that tension well are more complex than a template, and complexity is itself a failure mode when the person who understood it is the one who died.
• Crypto is in the taxable estate at its value on the date of death whether or not anyone can reach it, and a volatile asset can be valued at a level it does not hold when the estate is settled.
• A plan goes stale quietly. Nothing tells an executor that the inventory they are holding describes a wallet that was emptied two years ago.
