- The UK will defer Capital Gains Tax on certain crypto lending and liquidity pool transactions starting April 2027.
- HMRC will apply a “no gain, no loss” treatment until users make an actual economic disposal of their crypto.
- The changes are expected to simplify tax reporting for roughly 700,000 crypto investors participating in DeFi.
The UK government has announced major changes to the way certain decentralized finance (DeFi) transactions will be taxed, introducing new rules that defer Capital Gains Tax (CGT) on qualifying crypto lending and liquidity pool activities.
Under the updated framework, HM Revenue & Customs (HMRC) will apply a “no gain, no loss” treatment to specific cryptoasset loan and liquidity pool transactions. Rather than triggering an immediate taxable event, gains and losses will generally be recognized only when users make an economic disposal of the underlying cryptocurrency.
The new rules will take effect on April 6, 2027, and apply to individuals and trustees participating in eligible crypto lending and automated market-making arrangements.
HMRC Changes How DeFi Transactions Are Taxed
The revised rules cover several common DeFi activities that previously created complex tax obligations.
When users lend cryptocurrency and receive an interest in a lending arrangement involving the same type of cryptoasset, the transaction will generally be treated as no gain, no loss, meaning no Capital Gains Tax is triggered at that point.
The same treatment will also apply to qualifying liquidity pool deposits on automated market makers, provided users receive back the same quantity of cryptocurrency when exiting the pool.
If investors receive more or less than they originally deposited, only the difference will be used to calculate any taxable gain or allowable loss.
New Rules Aim to Match Economic Reality
HMRC said the changes are designed to better reflect the economic substance of DeFi transactions rather than taxing technical movements of assets that do not represent a genuine disposal.
The update also changes how borrowed cryptoassets are treated. Under the new framework, borrowed digital assets will generally be considered acquired at their market value when borrowed, while collateral posted during the transaction will not create a Capital Gains Tax event.
Officials believe the approach will make crypto taxation significantly easier for users participating in lending protocols and decentralized liquidity pools.
Reform Follows Years of Industry Feedback
The policy addresses concerns raised after HMRC’s 2022 crypto tax guidance, which many industry participants argued created unnecessary administrative burdens for DeFi users.
Following a public consultation in 2023, the government worked to redesign the rules so taxation more closely aligns with actual economic gains and losses rather than blockchain mechanics.
According to HMRC, approximately 700,000 individuals are expected to benefit from the simplified framework once it takes effect.
UK Continues Refining Its Crypto Tax Framework
Under the current UK tax system, selling, swapping, or spending cryptocurrency generally triggers a Capital Gains Tax event. Tax rates currently stand at 18% for basic-rate taxpayers and 24% for higher-rate taxpayers.
The new legislation does not eliminate Capital Gains Tax on crypto investments. Instead, it delays taxation for certain DeFi activities until investors ultimately dispose of their assets in a way that produces a genuine economic gain or loss.
HMRC said the measure is not expected to have a significant impact on the broader economy, with final cost estimates to be reviewed by the Office for Budget Responsibility at a future fiscal event.
