HMRC begins collecting full UK crypto transaction and profit data from 1 January 2026
From 1 January 2026, HMRC is requiring crypto exchanges serving UK users to provide complete transaction records, including tax residency and profit details. From 2027, this information will be exchanged automatically with tax authorities in 47 other jurisdictions, and UK individuals with gains above £3,000 may fall under capital gains or, in some cases, income tax rules.
