Since 1 January 2026, UK cryptoasset exchanges must collect detailed user and transaction data under the Cryptoasset Reporting Framework and report it directly to HMRC, with exchanges facing penalties of up to £300 per user for incomplete reporting. Crypto gains are almost always taxed as Capital Gains Tax on disposal, against an annual exempt amount of £3,000, though frequent trading or mining can instead be treated as income.
We calculate gains across wallets and exchanges, apply the correct Capital Gains Tax or Income Tax treatment, and prepare the Self Assessment reporting for crypto investors and traders across Slough.
Before the Cryptoasset Reporting Framework, HMRC largely relied on individual taxpayers to self-report crypto gains, and enforcement was inconsistent. From January 2026, UK exchanges are legally required to report user identity and transaction data directly to HMRC, in the same way banks already report interest income. Anyone assuming their crypto activity is invisible to HMRC is now working from an outdated assumption. This is exactly why unreported gains from previous years need reviewing now, before HMRC’s own data prompts a compliance check. We review trading history across every wallet and exchange a client has used, not just the most recent one.
