UK Will Stop Taxing Crypto Loans and Liquidity Pools as Taxable Events Starting April 2027

HM Revenue & Customs published a policy paper Monday laying out new tax rules for crypto lending and liquidity pool transactions. Most of these transactions won't trigger a Capital Gains Tax bill anymore. Tax gets deferred until someone actually disposes of the underlying cryptocurrency for something else.

The rules take effect 6 April 2027 and amend the Taxation of Chargeable Gains Act 1992, according to the policy paper cited by Bitcoin Magazine and reported by ZeroHedge. HMRC estimates roughly 700,000 individuals who lend crypto or provide liquidity to pools will be affected.

What Actually Changes

Three scenarios get the new treatment. First, single cryptoasset lending: if you lend out crypto and get an equivalent interest back in the same type of asset, that's now a "no gain, no loss" event. No tax owed until you actually cash out or swap into something different.

Second, borrowing arrangements: borrowed cryptoassets get valued at market price when you borrow them, and any collateral you put up gets disregarded for Capital Gains Tax purposes.

Third, automated market-making, meaning liquidity pools run through smart contracts. Same deal. Put crypto into a pool, get a pool-token interest back in the same asset type, no taxable event. When you exit, if you get back exactly what you put in, still no gain or loss. If you get back more or less than you put in, that difference is taxed as a gain or loss.

Why This Happened

This isn't HMRC being generous out of nowhere. It's a fix for a problem HMRC created itself.

HMRC's 2022 guidance treated crypto lending and liquidity pool deposits as taxable disposals, meaning every time someone moved crypto into a lending protocol or a liquidity pool, it could count as selling that asset for tax purposes, according to Bitcoin Magazine's reporting via ZeroHedge. Stakeholders complained this created enormous paperwork and tax liability for people who hadn't actually realized any economic gain. You'd owe tax on a transaction where you still held essentially the same asset, just wrapped in a different form.

HMRC opened a call for evidence from July to August 2022, then ran a formal consultation from 27 April to 22 June 2023, seeking to align the tax code with the actual economics of DeFi lending and liquidity provision. HMRC published a summary of responses at Budget 2025 and laid out its planned approach then. Monday's policy paper is the follow-through on that.

The Fair Read on This

There's a reasonable argument that any tax deferral scheme risks becoming a loophole, letting people shuffle assets around indefinitely to dodge a tax event permanently rather than merely delaying it. That's a legitimate concern anyone auditing tax policy should raise, and it deserves scrutiny once the rules are live and people start using them at scale.

The mechanism only defers tax, it doesn't eliminate it. If you get back a different quantity of crypto than you put into a pool, that difference is taxed as a gain or loss on exit, per the policy paper. The tax obligation doesn't vanish. It just attaches to the transaction where you actually realize an economic gain, instead of an intermediate step where you're moving the same asset from one place to another.

That's a defensible principle. Taxing people on paper transactions where nothing has actually been gained or lost is bad tax policy regardless of what asset class is involved. If HMRC applied the same no-gain-no-loss logic to some traditional financial instrument, few would call it a giveaway.

What's Still Unclear

HMRC's technical guidance, the Cryptoassets Manual, was last updated 28 November 2025 according to GOV.UK, and separate reporting requirements for cryptoasset service providers take effect 1 January 2026. The published materials don't clarify how those reporting rules will interact with the new no-gain-no-loss treatment, or what documentation individuals will need to prove they received the "same type and quantity" of asset back from a lending or pool arrangement.

The rules don't take effect until 6 April 2027, nearly two years out. Between now and then, HMRC will presumably issue further technical guidance on how individuals and trustees should track cost basis across these arrangements, and whether platforms operating in the UK will need to report transaction details to HMRC directly under the new service provider rules starting January 2026.
