Archax, the firm Bybit UK operates under, is FCA-registered and will therefore have to comply with any existing regulatory frameworks in the UK, including the OECD's Crypto-Asset Reporting Framework (CARF), which is designed to improve international tax transparency.
What do crypto exchanges report to HMRC?
Under CARF, all UK-based crypto platforms are required to collect and report detailed customer information to HMRC. This includes users’ full names, addresses, countries of residence, wallet addresses, and comprehensive transaction records, covering transfers, disposals, gross proceeds, and the fair market value of crypto assets.
Exchanges began collecting this information in January 2026, with reporting due for the 2026 calendar year by May 2027. Failure to comply could result in penalties of up to £300 per user.
