Certain cryptoasset loans, borrowing arrangements and AMM liquidity pool transactions will be treated as no gain, no loss until an economic disposal, a change expected to affect about 700,000 participants.
UK HM Revenue and Customs will apply a "no gain, no loss" Capital Gains Tax treatment to certain cryptoasset lending, borrowing and automated market maker liquidity pool arrangements from April 6, 2027, deferring tax until an economic disposal occurs. The change will apply to individuals and trustees and HMRC estimates it will affect about 700,000 participants. Under the new rules, single-asset lending deposits and certain AMM pool deposits of the same type of cryptoasset will not trigger an immediate gain or loss, while in borrowing arrangements the borrowed crypto will be treated as acquired at market value at the time of borrowing and posted collateral will be excluded from CGT calculations. On AMM withdrawals, tax treatment will remain neutral if the amount returned matches the amount originally deposited, with any gain or loss recognized only on any difference. HMRC said the policy responds to concerns that its 2022 guidance created excessive administrative burdens for taxpayers.
