Crypto Inheritance UK — What Happens to Cryptocurrency When You Die

Guide to cryptocurrency inheritance in the UK. How to ensure your crypto passes to beneficiaries, tax implications, and practical steps to prevent lost assets.

Billions of pounds in cryptocurrency is estimated to be lost forever because owners died without leaving access details. Here’s how to ensure your crypto passes to your beneficiaries.

The Problem with Crypto Inheritance

Why Crypto Is Different

Traditional Assets Cryptocurrency
Banks know the owner No central authority
Probate grants access Private keys required
Can be traced May be unknown to exist
Recoverable with death cert Lost without keys = lost forever

The Scale of Lost Crypto

Estimate Amount
Lost Bitcoin globally 3-4 million BTC
Often due to Death or lost keys
UK holders affected Unknown but significant

UK Tax Position

Crypto and Inheritance Tax

Rule Details
Treated as property Not currency
Part of estate For IHT calculation
Valued at death Market value that day
IHT rate 40% above threshold

IHT Thresholds (2025/26)

Threshold Amount
Nil-rate band £325,000
Residence nil-rate band £175,000
Combined (to direct descendants with home) £500,000
Married couple (with transfers) Up to £1,000,000

Example: Crypto in Estate

Asset Value
House £350,000
Savings £100,000
Crypto £150,000
Total estate £600,000
Above threshold (£500k) £100,000
IHT at 40% £40,000

Capital Gains Tax Reset

CGT Rule At Death
Base cost Resets to value at death
Previous gains Wiped out
Beneficiary sells later CGT only on gains since death

This can be advantageous — large gains aren’t taxed at death.
