Inheritance tax applies: Crypto is taxable property in most jurisdictions

Introduction

What happens to your Bitcoin when you die? Unlike bank accounts, cryptocurrencies don’t have a “next of kin” notification system. Without proper planning, your digital assets could be lost forever—locked in wallets that no one can access.

An estimated 3-4 million Bitcoin (worth over $300 billion) are already permanently lost due to forgotten passwords and deceased owners who left no access instructions. This guide ensures your crypto doesn’t join them.

The Core Problem: Private Keys

Cryptocurrency ownership is proven through private keys—long strings of characters that authorize transactions. Unlike bank accounts:

No central authority can “reset” your access
No customer service can recover your wallet
If keys are lost, the crypto is lost forever

This creates a unique estate planning challenge: you must ensure heirs can access your keys without compromising security during your lifetime.

Legal Status of Crypto Inheritance

In most jurisdictions, including France, the US, and UK:

Cryptocurrencies are considered property subject to inheritance laws
They pass to heirs according to your will (or intestacy laws if no will exists)
Inheritance tax applies based on the value at date of death
Heirs must report inherited crypto for tax purposes

5 Methods for Crypto Inheritance Planning

1. Traditional Will + Secure Storage

Include crypto in your will and store access instructions separately:

Mention crypto holdings in will (without specific keys)
Store seed phrases in bank safe deposit box
Give executor instructions to access the safe

2. Letter of Instruction

A detailed document (separate from the will) explaining:

What crypto you own and where it’s stored
How to access hardware wallets
Exchange account credentials
Step-by-step recovery instructions

3. Multisignature Wallets

Create a wallet requiring multiple signatures (e.g., 2-of-3):

You hold one key
Your heir holds another
A trusted third party (attorney, service) holds the third

This prevents unauthorized access while ensuring recovery is possible.

4. Crypto Inheritance Services

Specialized services like Casa, Unchained, or notary-backed solutions offer:

Secure key storage
Dead man’s switch (automatic notification after inactivity)
Legal integration with estate planning

5. Time-Locked Transactions

Advanced users can create transactions that automatically execute after a certain date unless cancelled—ensuring assets transfer even without action from heirs.

Common Mistakes to Avoid

Storing keys only in your head: Memory isn’t permanent
Telling no one: Heirs can’t claim what they don’t know exists
Storing keys with the will: Wills become public documents after probate
Using only one storage method: Redundancy prevents loss
Forgetting exchange accounts: Include centralized exchange credentials too

Tax Implications for Heirs

When inheriting crypto:

Inheritance tax is calculated on fair market value at death
Cost basis typically “steps up” to value at death (favorable for heirs)
Future sales may trigger capital gains tax
Reporting requirements vary by jurisdiction

📚 Glossary

Private key: Secret code proving cryptocurrency ownership and authorizing transactions.
Seed phrase: 12-24 word backup that can regenerate all private keys in a wallet.
Multisig: Wallet requiring multiple signatures to authorize transactions.
Dead man’s switch: System that triggers action if user doesn’t check in periodically.

Frequently Asked Questions

What happens to Bitcoin when someone dies?

Bitcoin doesn’t automatically transfer. Heirs need access to private keys or seed phrases to claim the crypto. Without proper planning, the Bitcoin may be permanently lost.

Should I include crypto in my will?

Yes, mention crypto holdings in your will, but store access credentials separately (not in the will itself, which becomes public). Include detailed instructions for heirs on how to access your crypto.
