What changed in April 2025

The UK's remittance basis regime was substantially reformed from 6 April 2025 and replaced with a new Foreign Income and Gains (FIG) regime for eligible new arrivals. Individuals who were not UK tax resident in any of the preceding 10 tax years may claim FIG relief on foreign income and gains for up to 4 tax years.

Is crypto a foreign or UK asset?

The location of crypto for tax purposes is complex and depends on factors such as where the owner is resident, where the exchange is based and where the private keys are held. For non-doms and FIG claimants, the situs of the asset matters — specialist advice is essential.

Remittance basis and historic gains

Individuals who claimed the remittance basis before April 2025 may still have historic gains that are only taxable on remittance to the UK. Managing these carefully requires specialist planning.

Frequently asked questions

Do I pay UK CGT on crypto gains if I am non-domiciled?

This depends on your specific status, whether you have claimed or can claim FIG relief, and the situs of the crypto. The rules changed substantially in April 2025. Specialist UK tax advice is essential.
