Under HMRC rules, crypto assets are treated as chargeable assets for capital gains tax (CGT) purposes, meaning realised losses can be used to offset gains and, in some cases, carried forward to future years.

The annual CGT exemption is now only £3,000, down 75% in just two years, meaning even modest gains can now trigger a tax bill.

Analysis from The Investors Centre shows that despite the scale of this opportunity, many investors may not take action before the end of the tax year in April 2026.
