What is the no gain, no loss tax treatment?

The no gain, no loss tax treatment is a Capital Gains Tax framework that defers the recognition of gains or losses on certain crypto transactions until a user makes an economic disposal of the underlying asset. Under this approach, specific activities involving cryptoassets—such as lending or providing liquidity to automated market-making pools—are not treated as taxable disposals at the time they occur. Instead, the tax liability is postponed until the user exits the arrangement and receives back their cryptoassets or realizes a difference in value.

HMRC said the change aligns tax treatment with the economics of these arrangements, recognizing gains and losses only when a participant makes an economic disposal. The measure modifies the disposal rule for certain lending and liquidity pool arrangements, which previously created administrative challenges under HMRC's 2022 guidance. The new framework is designed to be easier to understand and reduces the compliance burden for users who engage in decentralized finance activities.

How the new rules work for crypto lending

The rules cover three scenarios, according to the policy paper. In a single cryptoasset lending arrangement, a user who acquires or disposes of an interest in exchange for cryptoassets of the same type as those invested will be taxed on a no gain, no loss basis. This means that when a user lends their cryptoassets and receives an interest in the lending arrangement, the transaction is not treated as a taxable disposal at that moment. The tax liability is deferred until the user exits the arrangement and receives back their cryptoassets or realizes a gain or loss.

Borrowing arrangements will treat borrowed cryptoassets as acquired at market value at the time of borrowing, with any collateral disregarded for Capital Gains Tax purposes. This treatment ensures that the borrower's tax position reflects the market value of the borrowed assets at the time of the transaction, while the collateral provided does not trigger a separate tax event. The approach simplifies the tax calculation for users who borrow cryptoassets and provides clarity on how the acquisition cost should be determined for future disposal calculations.

How the rules apply to liquidity pools

For automated market-making arrangements—liquidity pools operated through smart contracts—a user acquiring an interest in exchange for the same type of cryptoasset is also taxed on a no gain, no loss basis. When a user deposits cryptoassets into a liquidity pool and receives a liquidity pool token or interest in return, the transaction is not treated as a taxable disposal at that time. The tax liability is deferred until the user exits the pool and receives back their cryptoassets.

On exit, that treatment holds to the extent the user receives the same quantity first invested. Any difference between what was invested and what is received triggers a gain or a loss. This means that if a user deposits 10 units of a cryptoasset and later withdraws 10 units, the transaction is treated as no gain, no loss. However, if the user withdraws 12 units, the additional 2 units represent a gain and are subject to Capital Gains Tax. Conversely, if the user withdraws only 8 units, the shortfall of 2 units represents a loss that can be used to offset other capital gains.

Why HMRC changed the tax treatment

The measure addresses problems that arose from HMRC's own 2022 guidance, which stakeholders said produced disproportionate administrative burdens. A call for evidence ran from July to August 2022, followed by a consultation between 27 April and 22 June 2023 that sought to align tax with economic substance by not treating crypto used in DeFi lending and liquidity pools as a taxable disposal. HMRC published a summary of responses at Budget 2025 and set out its approach at that time.

HMRC simplifies DeFi crypto tax rules by recognizing that users who lend cryptoassets or provide liquidity to automated market-making pools have not yet realized an economic gain or loss at the time of the transaction. The previous guidance treated these activities as taxable disposals, which created significant compliance challenges for users who engaged in multiple transactions. The new framework reduces the administrative burden and provides a clearer tax treatment that reflects the economic reality of these arrangements.

Who is affected by the new rules

The change is expected to affect about 700,000 individuals who engage in these transactions, according to the paper. HMRC said users will benefit from a framework that is easier to understand. The measure applies to individuals and trustees who enter cryptoasset loan and liquidity pool arrangements, and it takes effect 6 April 2027. The rules are designed to provide clarity for users who participate in decentralized finance activities and to reduce the compliance burden associated with tracking and reporting multiple taxable disposals.

Final costing will be subject to scrutiny by the Office for Budget Responsibility and set out at a future fiscal event. HMRC said the measure is not expected to have any significant macroeconomic impact. The policy paper indicates that the new treatment is intended to align the UK's tax framework with the economic substance of crypto lending and liquidity pool arrangements, while maintaining the overall structure of the Capital Gains Tax regime for cryptoassets.

How the new treatment differs from current UK crypto tax rules

The current UK regime treats crypto as an investment asset, with selling, swapping, or spending it counting as a disposal for Capital Gains Tax at 18% for basic-rate taxpayers and 24% for higher-rate taxpayers. Under the existing rules, any transaction that involves disposing of a cryptoasset—whether by selling it for fiat currency, exchanging it for another cryptoasset, or using it to purchase goods or services—triggers a Capital Gains Tax liability. This treatment applies to all cryptoasset transactions, including those involving lending and liquidity pools.

The new treatment modifies that disposal rule for certain lending and liquidity pool arrangements. Instead of treating the initial transaction as a taxable disposal, the no gain, no loss framework defers the tax liability until the user exits the arrangement and realizes an economic gain or loss. This change reduces the number of taxable events that users must track and report, and it aligns the tax treatment with the economic substance of the transaction. The new rules do not change the Capital Gains Tax rates or the overall treatment of cryptoassets as investment assets; they only modify the timing of when the tax liability is recognized for specific types of transactions.

What to watch next

Readers should watch for additional guidance from HMRC on how the no gain, no loss treatment will be applied in practice, including any clarifications on the types of lending and liquidity pool arrangements that qualify for the new treatment. The policy paper provides a high-level overview of the rules, but further details may be needed to address specific scenarios and edge cases. Users who engage in crypto lending and liquidity pool activities should also monitor any updates to the Capital Gains Tax rates or the broader tax treatment of cryptoassets, as these could affect the overall tax liability when the deferred gains or losses are eventually recognized.

The measure takes effect 6 April 2027, which provides users with time to prepare for the new rules and adjust their record-keeping and reporting practices. Final costing will be subject to scrutiny by the Office for Budget Responsibility and set out at a future fiscal event, which may provide additional context on the expected revenue impact and the number of users affected. Readers should also watch for any changes to the UK's broader regulatory framework for cryptoassets, as tax treatment and regulatory oversight are often closely linked.
