Crypto Estate Planning: Passing Digital Assets to Heirs

12 November 2026

Under federal tax rules, the day someone dies can reset the tax math on their crypto. Inherited property generally takes a stepped-up cost basis equal to its fair market value on the decedent's date of death, according to Internal Revenue Code Section 1014, as summarized by estate-planning firm DAG. For heirs, that can mean years of gains disappear from the tax calculation. The tax rule is the easy part of crypto inheritance, though. Getting into the wallet at all is harder.

Tax rules that shape what heirs receive

The starting point is how the IRS classifies the asset. In its frequently asked questions on digital asset transactions, the agency says digital assets are treated as property for federal tax purposes. That single classification pulls crypto into the same framework as stocks, real estate and other property, including the concept of basis: what the owner paid, which determines the gain or loss when the asset is sold.

Section 1014 is where inheritance gets its distinct treatment. Because inherited property generally takes a basis equal to its fair market value on the date of death, an heir who sells shortly afterward may owe little or no tax on the appreciation that built up during the original owner's lifetime. Someone who bought a coin years earlier at a fraction of its current price, and never sold, can pass it on with the unrealized gain effectively wiped out for income tax purposes. This is one reason many advisers treat holding crypto until death very differently from giving it away during life.

The contrast with lifetime gifts is worth spelling out. The IRS says that if you do not have documentation to substantiate the donor's basis, your basis is zero. A recipient of gifted crypto who cannot prove what the donor paid could therefore face tax on the entire sale price as gain. Gifts and inheritances follow different rules, and the paperwork requirements differ with them.

Records still matter after a death, even with the step-up. Heirs and executors need to establish the value on the date of death, and they need to identify which wallets and accounts held the assets. A person who kept scattered exchange statements, wallet addresses and transaction histories leaves a far cleaner trail than one who kept nothing. Anyone planning an estate should treat record-keeping as part of the inheritance itself, and should expect a tax professional to ask for it.

Who can get access after death or incapacity

Tax treatment assumes the heirs can reach the assets in the first place. Here the law has largely caught up. The Revised Uniform Fiduciary Access to Digital Assets Act, known as RUFADAA, has been enacted in 46 states plus the District of Columbia, according to figures cited by Spark Money. The law gives executors, trustees, agents under a power of attorney and similar fiduciaries a legal framework to request access to a person's digital assets and accounts.

Texas is one of the states that has adopted it. Planners there advise that estate documents should expressly address fiduciary access to digital assets and should work alongside a secure private record of how the Bitcoin is accessed. That advice applies well beyond Texas. A will or trust that never mentions digital assets leaves a fiduciary arguing from general authority, while one that names them gives the fiduciary something concrete to show a custodian.

The practical meaning of RUFADAA depends on what kind of crypto the person held. If the assets sat on an exchange or with another third-party custodian, a fiduciary with proper authority has a legal path to approach that company, and the statute gives the request a footing. If the person held coins in self-custody, the situation changes, because no company holds anything for the fiduciary to ask for. As Forklog's guide to inheriting crypto puts it, the law gives fiduciaries a framework but cannot recover a private key that nobody has.

That distinction should shape how a self-custody holder plans. Legal authority is a necessary piece, but it works only when paired with a way to get at the keys. The same applies to incapacity, not just death. A person who suffers a stroke or serious accident while alive may need a trusted agent to manage holdings, and a power of attorney that addresses digital assets will not help if the agent has no route to the wallet.

Will, trust, or both: which document should carry crypto instructions

Many people assume a will is the place for everything. For crypto, that assumption carries a specific hazard. A will can become a public record once it enters probate, which can expose recovery phrases if they are included in the document. Anyone who can read the probate file could, in principle, read the words that control the wallet. Writing a seed phrase into a will, even with good intentions, can turn a private safeguard into a public liability.

A trust works differently. According to DAG's estate-planning FAQ, a trust can keep details private and provide continuous control during incapacity, while a will passes through probate. Continuity is the less obvious benefit. If the owner becomes unable to manage assets, a successor trustee can step in under the trust's terms without waiting for a court process, which matters for volatile assets that may need attention at short notice.

The same publisher adds a caveat in its comparison of crypto wills and trusts: a properly funded trust can avoid probate and add privacy and continuity for digital assets. The word "funded" carries weight. A trust that is signed but never connected to the assets does little. Funding means the assets are actually placed under the trust's control, which for crypto raises its own practical questions about titling accounts and documenting how the trustee will reach wallets. An attorney who works with digital assets can say how that should be done in a given state.

For many families the answer is both. A will remains useful as a backstop for anything not placed in the trust, and a trust handles the assets where privacy and speed matter. Whichever documents are used, the instructions about where the crypto is and how it is reached belong in a separate, secure record rather than in the text of a document that may become public.

Practical custody steps for self-custody and exchange accounts

Documents set out who has authority. The operational work is making sure that authority leads somewhere. The steps below apply to both self-custody and exchange holdings, and they work best when done while the owner is healthy and can test them.

  • Build an access inventory: list every exchange account, wallet, and device that holds or reaches crypto, along with the approximate purpose of each, without writing the secrets themselves into the list.
  • Write instructions for the fiduciary: explain in plain language what exists, where the private record is kept, who should be contacted first, and what the owner wants done with the assets.
  • Store keys and recovery phrases securely and separately: keep them in a protected private record that is not part of the will or any document that may enter probate.
  • Plan for exchange accounts: make sure the executor or trustee knows which platforms hold assets, and that the estate documents expressly give fiduciaries authority over digital assets so a custodian's request process can be satisfied.

The separation between instructions and secrets is the detail people most often get wrong. Instructions can be shared with a lawyer, an executor and a family member. The keys themselves should live in a secure private record, and the estate documents should point to its existence and location rather than reproduce it. That way a probate filing reveals only that a record exists.

Testing matters too. An owner who has never walked a trusted person through the process cannot know whether the written steps make sense to someone less technical. A dry run, done without exposing the real secrets to anyone who should not have them, often reveals missing pieces: a device that requires a passcode nobody recorded, or an account tied to an email address the heirs cannot open.

Records should also be refreshed. Wallets get replaced, exchange accounts get closed and holdings change. An inventory from several years ago may point to accounts that no longer exist while missing the ones that matter most, so an annual review is a reasonable habit.

What can and cannot be solved by planning documents

Wills, trusts and statutes can grant authority, define who is in charge and keep private details out of the public file. What they cannot do is reconstruct a key that has been lost. RUFADAA helps a fiduciary approach custodians and gives that fiduciary a recognized legal role, but it cannot recover a private key that nobody has. If the only copy of a recovery phrase disappeared with its owner, no court order or well-drafted clause will bring it back.

The reverse failure is just as real. A recovery phrase copied into a will for safekeeping can be exposed once the will becomes a public record in probate. Between those two failures lies the narrow path that sound planning follows: keep the secret safe enough that it cannot be stolen, and accessible enough that the right person can find it when needed.

For readers in the US, the sensible sequence is straightforward. Gather the records that establish what is held and what was paid. Have an estate attorney draft documents that expressly cover digital assets under your state's version of RUFADAA, and ask whether a funded trust makes sense alongside a will. Then set up the secure private record and make sure one trusted person knows how to find it. Do it before it is needed, because after death or incapacity no document can supply a key that was never saved.
