HMRC to Defer Crypto Capital Gains on Lending and Liquidity Pools With ‘No Gain, No Loss’ Rule From April 2027

The UK’s HM Revenue and Customs will adopt a “no gain, no loss” approach for certain cryptoasset transactions linked to lending and liquidity pools starting April 6, 2027, a move the agency says will defer capital gains tax on digital assets until an “economic disposal.” The policy shift is intended to better match tax outcomes with the underlying economics of decentralized finance activity and is expected to affect roughly 700,000 individuals and trustees. HMRC policy statement.

The Development

In guidance published Monday, HMRC said it will apply a “no gain, no loss” treatment to specific disposals connected to crypto lending and liquidity pool participation. Under the measure, capital gains taxation would be deferred “until an economic disposal,” shifting the taxable event to when participants ultimately exit with an economic change in ownership.

The authority framed the rule as promoting equity and accuracy in the tax system. “This measure will support fairness in the tax system,” HMRC said, adding that it “aligns the tax treatment more closely with the economics of these arrangements by ensuring that gains and losses are generally recognized only when the participant makes an economic disposal of the cryptoassets.” HMRC policy statement.

According to the agency, “no gain, no loss” will apply under UK capital gains rules in circumstances that include the acquisition or disposal of an interest in a lending arrangement in exchange for the same type of asset, borrowed assets acquired at market value, and similar conditions involving automated market makers.

Background and Context

HMRC’s move marks a significant change from the authority’s 2022 guidance on crypto liquidity pools and lending, following a consultation period. The new approach responds to features of decentralized protocols in which users temporarily transfer or combine tokens without a traditional change in beneficial ownership until later redemption or exit. By deferring recognition, the measure addresses timing mismatches that can arise when tokens are deposited into lending contracts or pooled with automated market makers.

The agency estimates the change will impact about 700,000 individuals and trustees, indicating a broad taxpayer footprint across retail and non-corporate participants engaging in lending and liquidity provision. HMRC also emphasized that aligning tax events with economic disposals is intended to reflect how value is realized in these arrangements.

For the 2025–2026 tax year, UK taxpayers pay between 18% to 24% for capital gains related to crypto transactions depending on whether they qualify as basic-rate or higher-rate taxpayers. UK income tax rates.

Industry Reaction

Initial reaction from parts of the decentralized finance sector was supportive. “This is the right direction, mainly driven by the industry feedback demonstrating that any other approach would cause significant admin burden for the tax payer,” Aave founder and CEO Stani Kulechov said in an X post on Monday.

Market participants involved in liquidity provision and lending have long highlighted the administrative complexity of tracking numerous token movements across protocols. HMRC’s explicit aim to recognize gains and losses when there is an economic disposal speaks to these operational concerns by reducing interim tax triggers tied to mechanical transfers that do not reflect realized value.

Potential Impact

Deferring capital gains recognition until an economic disposal could streamline compliance for individuals and trustees active in lending pools and automated market makers by clarifying when taxable events occur. Under a “no gain, no loss” treatment for qualifying disposals, many interim transactions associated with entering or adjusting positions in lending arrangements and pools may not create immediate capital gains calculations. That approach can reduce the frequency of reportable events and improve the alignment between tax liabilities and actual value realization.

For taxpayers, the change may offer clearer planning around the lifecycle of DeFi participation. Rather than treating every deposit, withdrawal, or token exchange within a pool structure as potentially taxable, HMRC’s framework indicates that taxation will arise when participants make an economic disposal. That could mitigate uncertainty and reduce the administrative burden described by industry stakeholders.

The measure’s scope—covering acquisitions or disposals of interests in lending arrangements in exchange for the same type of asset, borrowed assets acquired at market value, and analogous conditions with automated market makers—signals a concerted focus on common DeFi mechanisms. By addressing how these specific interactions are treated for capital gains purposes, HMRC is providing a reference point for taxpayers and advisors navigating lending and liquidity activity.

Legal and Compliance Implications

HMRC’s timeline sets a clear start date of April 6, 2027. The delayed effective date provides time for individuals and trustees to evaluate how their participation in lending arrangements and liquidity pools may be affected and to adjust record-keeping and reporting processes accordingly. Because the approach is anchored in the concept of an “economic disposal,” taxpayers will still need to substantiate when that point occurs and maintain supporting documentation consistent with UK capital gains requirements.

The move follows the authority’s prior work in 2022 on crypto lending and liquidity pool guidance and the subsequent consultation period referenced by HMRC. The new position—expressly articulated as promoting fairness and alignment with the economics of these arrangements—reflects an effort to address the treatment of token flows that may not immediately translate into realized gains or losses for participants.

For the 2025–2026 tax year, the stated capital gains rates of 18% to 24% for crypto transactions, depending on basic-rate or higher-rate status, remain a benchmark for taxpayers assessing potential liabilities when an economic disposal ultimately occurs. UK income tax rates.

What’s Next

The “no gain, no loss” policy for certain cryptoasset lending and liquidity pool disposals takes effect on April 6, 2027. Between now and implementation, taxpayers engaging with lending arrangements and automated market makers can review HMRC’s published guidance and consider how the rule’s emphasis on economic disposal interacts with their participation strategies and reporting practices.

In UK politics, Reform leader Nigel Farage will not stand completely uncontested in a by-election caused by his resignation last week amid reports of the politician receiving contributions from billionaires tied to the crypto industry. On Tuesday, Stephen Newnham, leader of the Solana community group Superteam UK, said he will run as an independent candidate against Farage and others. The by-election representing Clacton is scheduled for Aug. 13 and will include candidates such as comedian and author Jon Harvey in costume as Count Binface, a self-described “independent space warrior.” Farage triggered the by-election with his resignation, saying he wanted the people of Clacton to judge his actions. He reportedly received a $6.7 million donation from crypto billionaire Christopher Harborne—described as a “reward” for the UK’s exit from the European Union and later as a “gift”—and other financial assistance from George Cottrell, a convicted fraudster linked to a crypto casino.

As HMRC’s deferral framework approaches its April 2027 start date, taxpayers, advisers, and market participants will be focused on how the “no gain, no loss” treatment applies across the transactions HMRC identified—particularly interests acquired or disposed of in exchange for the same type of asset, borrowed assets acquired at market value, and similar conditions with automated market makers—and how those touchpoints shape reporting obligations when an economic disposal occurs.
