UK Tax Authority Set to End CGT Trigger on DeFi Deposits, Deferring Gains Until Actual Disposal
HMRC has moved to adopt a "no gain, no loss" framework for crypto lending and liquidity pool transactions, a change that would remove a rule generating more than a hundred taxable events per year for users adding and removing liquidity weekly, with no real economic gain behind most of those events.
HMRC has moved to adopt a "no gain, no loss" framework for crypto lending and liquidity pool transactions, a change that would remove a rule generating more than a hundred taxable events per year for users adding and removing liquidity weekly, with no real economic gain behind most of those events. Draft legislation has not yet been published; the policy currently represents HMRC's stated intent rather than enacted statute.
The UK's tax authority confirmed its policy direction in a consultation outcome published on November 26, 2025. The Block reported on July 14, 2026 that the framework has since been reaffirmed as HMRC's intended approach, though it remains subject to formal legislative enactment.
Under the proposed approach, depositing crypto into a lending protocol or liquidity pool and later withdrawing it would no longer count as a taxable disposal for Capital Gains Tax (CGT) purposes. Tax liability would be deferred until a user makes a genuine economic exit, such as converting crypto to fiat or disposing of fundamentally different assets.
What Changed and Why It Matters
Under the prior rules, which HMRC inherited from 2022-era guidance, transferring ownership of a crypto asset to a smart contract was treated the same as selling it.
This meant a user adding and removing liquidity weekly from a platform like Uniswap or lending ETH through Aave could trigger more than a hundred separate CGT events in a single year, most of them reflecting no real profit.
HMRC opened a call for evidence in July 2022 and ran a formal consultation from April 2023, weighing three possible approaches. Respondents were split between two of those options, though the overwhelming consensus was that the current rules were unworkable. HMRC ultimately moved toward a bespoke no gain, no loss principle designed specifically for cryptoassets, distinct from the repo and stock lending rules that formed a separate option under consideration and were not adopted.
The new framework covers three main activity types: single-token lending (lending one asset and receiving the same asset back), collateralised borrowing (posting crypto as security for a loan without selling it), and multi-token automated market maker pools of the kind operated by Uniswap and Curve. Staking rewards are excluded and remain taxable as miscellaneous income at the point of receipt. The rules will apply to individuals first; whether companies receive equivalent treatment is still under review.
Stani Kulechov, CEO of Aave, one of the largest DeFi lending protocols by total value locked, welcomed the change. "A major win for UK DeFi users who want to borrow stablecoins against their crypto collateral," he said. "Borrowers aren't attempting to dispose of assets when locking tokens for liquidity."
The AMM Calculation Problem
Liquidity pools involving two assets, such as an ETH and USDC pair, add a practical complication. Because of price movements inside the pool, users rarely withdraw the exact quantities they deposited. HMRC's guidance, as analysed by law firm Freshfields, proposes treating shortfalls in withdrawn amounts as capital losses and any excess as capital gains.
A user who deposits 10 ETH and 30,000 USDC but withdraws 8 ETH and 38,000 USDC would record a capital loss on the two missing ETH (valued at £2,000) and a capital gain on the additional 8,000 USDC (valued at £8,000), producing a net taxable gain of £6,000. The framework also appears designed to address a pre-existing common law risk. The Marren v Ingles doctrine on unascertainable deferred consideration could theoretically have applied to AMM withdrawals where future token quantities are unknown at the point of deposit; the no gain, no loss approach appears designed to disapply that doctrine.
This approach is workable but requires precise records of every pool entry, the quantities of tokens deposited, and the cost basis of each asset.
Reporting Requirements Run Alongside the Tax Change
The no gain, no loss framework does not reduce reporting obligations. On a parallel track, HMRC extended the OECD's Cryptoasset Reporting Framework (CARF) to domestic UK residents from January 1, 2026. All UK-facing crypto platforms must now collect and report user transaction data, with the first international data exchanges scheduled for May 31, 2027, covering 2026 data.
Users in jurisdictions covered by CARF data-sharing agreements, including South Africa, will have their transaction records shared with local tax authorities regardless of whether any UK CGT event has been triggered.
Impact Beyond the UK
The policy carries practical weight in several regions with strong UK diaspora connections. Nigeria receives more than $30 billion in annual DeFi protocol inflows and ranks sixth globally in crypto adoption, with users frequently accessing platforms like Aave and Venus to borrow dollar-denominated liquidity against crypto holdings without selling.
For UK-based users with ties to Nigeria and South Asia alike, the proposed NGNL rules would directly reduce the compliance burden when using those same protocols for cross-border financial management.
The UK-India remittance corridor, the largest single outbound channel from the UK at £3.30 billion in 2024 and accounting for more than a third of all UK remittances, is seeing a growing fraction routed through crypto rails, including DeFi lending platforms used to hedge foreign exchange exposure.
UK-resident Indian investors who use DeFi platforms for yield stand to benefit under the proposed rules, which would remove the CGT calculation on every deposit and withdrawal. The contrast with India's own regime is significant: gains on virtual digital assets in India are taxed at a flat 30 percent under Section 115BBH, with a one-percent withholding tax on transactions, no equivalent no gain, no loss treatment for DeFi activity, and a regulatory grey zone around DeFi platforms more broadly.
Global DeFi total value locked, as of June 2026, sat at roughly $71.77 billion, down approximately 39 percent from around $115 billion at the start of 2026, with Ethereum holding a 53.1 percent share of that total.
Against that backdrop of reduced capital and elevated security risk (121 hacks totalling $942 million in losses year-to-date), regulatory clarity in a major jurisdiction carries real weight for protocols competing for institutional and retail liquidity. Sandy Jones of Baillie Gifford has pointed to such clarity as providing the "necessary legal certainty and governance standards for traditional financial institutions to adopt blockchain infrastructure," a dynamic directly relevant to DeFi protocols seeking to attract institutional flows.
Across Africa, Ghana's Virtual Asset Service Providers (VASP) Bill, advancing through its legislative process in 2025-26 alongside the creation of the Virtual Assets Regulatory Office (VARO), has drawn attention from observers who see the UK's NGNL model as a potential regional template.
What Comes Next
Draft legislation has not yet been published, and HMRC has confirmed there is no retrospective relief for historical DeFi positions. Users who closed positions under the old rules remain subject to the old CGT treatment and should take professional advice.
The UK's approach also stands in notable contrast to the European Union's Markets in Crypto-Assets (MiCA) regime, which does not specifically address AMM or DeFi tax treatment and applies more restrictive rules on stablecoin circulation. That distinction matters for UK-resident users and protocol operators weighing the two jurisdictions against each other in a post-Brexit environment.
For the industry more broadly, the four-year arc from HMRC's 2022 evidence call to the current policy position offers a working template for how other jurisdictions might develop their own frameworks. Nigeria's SEC and South Africa's FSCA have both signalled interest in DeFi-specific guidance. Whether the UK's own template hardens into statute will depend on when HMRC publishes its promised draft legislation.
