Part 4 of our "Crypto Explained Well" series. Crypto inheritance has a cruel twist no other asset has: your heirs can owe tax on coins they may never be able to touch. Here is how it works, with Italy as the worked example.
When someone dies holding crypto, two separate problems open at once: a legal/tax problem (it must be declared and taxed) and a technical problem (someone has to actually access it). These don't resolve together, and the gap between them is where families get hurt.
The Legal Side: It's Part of the Estate
In Italy, the 2023 Budget Law put crypto-assets on the same footing as other movable property for succession. That means crypto must be included in the dichiarazione di successione at its market value on the date of death, and it forms part of the taxable estate. The succession tax follows the ordinary rates — 4% for a spouse and children, each with a €1 million allowance — and Italian fiscal residence means Italy taxes the deceased's crypto wherever it sits, including foreign exchanges and hardware wallets abroad.
The cruel part: for self-custodied crypto, the declaration obligation exists even if the heirs cannot access the wallet. The tax is owed on the value; whether anyone can ever spend it is a separate question the law does not wait for.
The Technical Side: The Keys Are Everything
Crypto in self-custody is controlled by a private key or seed phrase. No key, no access — there is no "forgot password," no bank manager, no court that can recover it. If the deceased held coins in a hardware wallet and the seed phrase died with them, the assets are, in practical terms, gone — while the tax on them may still be due. On a custodial exchange the picture is better: heirs can present a death certificate and succession documents to claim the balance, and request a balance certification at the date of death for the tax filing.
Estate planning for crypto is key management, not just a will
A will can say who inherits the Bitcoin; it cannot give them the keys. The single most important thing a crypto holder can do for their family is ensure that the access — seed phrases, hardware-wallet locations, exchange accounts — is securely recoverable by the right people, through a sealed letter, a trusted executor, or a proper inheritance arrangement. Without it, you leave your heirs a tax bill for assets they can see on the blockchain forever and never spend.
For the Estate's Advisors
For the notary or accountant handling the estate, the first task is establishing what the deceased held and what it was worth at the date of death — across exchanges and on-chain. That reconstruction and valuation is the same work behind any crypto tax filing; see What Your Exchange Actually Sees for how the records are obtained.
