Leaving the UK with crypto — tax basics for emigrants
Quick answer: You generally remain liable for UK tax on crypto gains realised while UK-resident in that tax year. Split-year treatment may apply in some cases. Always take professional cross-border tax advice before large disposals around a move.
Emigrating mid-year does not automatically erase UK tax obligations on crypto disposed while you were UK-resident. Rules on residence and domicile are complex.
While you are UK-resident
Disposals during UK residence are typically in scope for UK CGT under normal rules. Plan timing of large sales with an adviser.
After you leave
Future liability depends on new residence, any UK-source gains, and double-tax treaties. HMRC and the tax authority in your new country may both be interested in your records.
Practical steps
Export all exchange history before closing UK accounts. Document wallet holdings at departure date. Do not assume offshore exchanges remove UK reporting obligations for past years.

Can I just leave crypto on a UK exchange?+
You may, but check exchange terms for non-UK residents and tax reporting in both countries.
