UK defers crypto capital gains tax for DeFi lending and pools
The UK will defer capital gains tax on certain crypto lending and liquidity pool transactions until an actual economic disposal takes place, relieving administrative burdens for roughly 700,000 investors.
HM Revenue & Customs will apply a "no gain, no loss" tax treatment to specific crypto-asset lending and liquidity pool arrangements, according to a policy paper published Monday. The change defers Capital Gains Tax until a user makes an actual economic disposal of the underlying cryptocurrency. The updated rules take effect on 6 April 2027.
The policy amends the Taxation of Chargeable Gains Act 1992 to address three distinct DeFi scenarios. When users participate in single crypto lending or automated market-making liquidity pools, exchanging tokens of the same type will not trigger an immediate taxable event. However, if a user exits a liquidity pool with a different quantity of tokens than initially invested, that discrepancy will trigger a capital gain or loss.
For borrowing arrangements, the framework dictates that loaned cryptoassets are treated as acquired at their market value at the exact time of borrowing. Crucially, any collateral posted to secure the loan is completely disregarded for Capital Gains Tax purposes. This removes the complex task of tracking collateral valuations during the lifespan of a DeFi loan.
The adjustment resolves friction caused by HMRC’s 2022 guidance, which industry stakeholders argued imposed disproportionate administrative burdens by treating routine DeFi interactions as taxable disposals. Under the current regime, swapping or spending crypto immediately triggers capital gains liabilities at 18% for basic-rate taxpayers and 24% for higher-rate taxpayers. The new approach delays this liability, ensuring tax is only levied when economic substance dictates.
Approximately 700,000 individuals and trustees who engage in these transactions will operate under the simplified framework. HMRC stated the measure aligns tax outcomes with the actual economics of decentralized finance. While the Office for Budget Responsibility will conduct final costings at a future fiscal event, the tax authority does not expect the rule change to produce any significant macroeconomic impact.
