The UK's tax authority will treat certain crypto lending and liquidity pool transactions as 'no gain, no loss' from April 2027, deferring Capital Gains Tax until users make an economic disposal. The measure, announced this week, is expected to affect about 700,000 individuals and aims to simplify tax reporting for DeFi users.
What the rule does
Under current rules, even routine DeFi transactions like lending tokens or adding to a liquidity pool can trigger a taxable event. HMRC's new policy changes that. From April 2027, these moves won't count as a disposal for CGT purposes. Instead, the tax bill is deferred until a user sells or otherwise converts the position back into fiat or another asset — what HMRC calls an 'economic disposal.'
Who's in scope
HMRC estimates roughly 700,000 people will be affected. That covers individuals who use crypto lending platforms or participate in automated market-maker liquidity pools. The agency didn't name specific protocols, but the rule applies broadly to any arrangement where tokens are lent or pooled in a way that the user retains an economic interest. It's not a blanket exemption — only transactions that meet the 'no gain, no loss' criteria qualify.
Why HMRC moved now
The policy is about simplifying compliance. DeFi users often face a maze of taxable events every time they move tokens in and out of smart contracts. By deferring the tax, HMRC is aligning the reporting burden with the actual economic gain — when someone cashes out. The move also brings the UK closer to the approach some other jurisdictions have taken, though the details differ.
What happens next
The new rules kick in from April 2027. HMRC hasn't yet published the full technical guidance, but it's expected to do so before the start of the 2027-28 tax year. For now, users and platforms should watch for the draft legislation, which will spell out exactly which transactions qualify and how to report them. The clock is ticking — there's about nine months until the new regime begins.
