The United Kingdom has announced its plans to introduce one of the most significant Crypto Liquidity Pool Tax reforms in recent history. His Majesty’s Revenue and Customs (HMRC), the primary tax, payment, and customs authority for the United Kingdom government, is replacing its controversial “dry tax” decentralized finance (DeFi) taxation approach with a new “no gain, no loss” approach to qualifying liquidity pool and lending transactions.
The rule change means that investors are no longer hit with Capital Gains Tax (CGT) obligations despite never selling their assets or receiving cash proceeds. Instead, taxation is deferred until a participant makes a genuine economic disposal.
HMRC has announced that the approach will only take effect from April 6, 2027. The change is aimed at making DeFi participation much more attractive while also providing greater clarity to the process of how liquidity pools and lending protocols are taxed.
Key Takeaways
- HMRC is replacing its existing DeFi tax treatment with a “no gain, no loss” approach.
- Depositing crypto assets into qualifying liquidity pools will no longer trigger immediate Capital Gains Tax.
- The reforms are scheduled to take effect on April 6, 2027.
- Taxation will generally be deferred until investors exit a liquidity pool or lending arrangement.
- Yield, staking rewards, and interest earned remain taxable.
- HMRC is also introducing new reporting requirements under the OECD’s Cryptoasset Reporting Framework.
- The changes aim to simplify crypto taxation and eliminate the controversial “dry tax” burden.
What Do the Rules Cover?
The rule will amend the currently existing Taxation of Chargeable Gains Act 1992, and the tax authority estimates that the change will affect around 700,000 individuals and trustees who use crypto loans and liquidity pools.
The rules focus on three scenarios.
- If an individual deposits crypto into a lending platform and receives an interest in the arrangement in return, there is no immediate Capital Gains Tax (CGT) if the individual later receives the same type of cryptoasset back. Tax is deferred until there is a real economic gain or loss.
- When an individual borrows crypto, HMRC considers the borrowed assets as being acquired at their market value on the date of borrowing. Any collateral provided for the loan is usually not considered for CGT purposes.
- If an individual deposits crypto into a liquidity pool and receives a pool interest back, the transaction is considered on a no-gain, no-loss basis. When the individual exits, the same consideration applies if the person receives the same amount of crypto that they originally deposited. If the individual receives more or less than what they put in, CGT applies to the difference, which either creates a taxable gain or an allowable loss.
What Prompted the Amendment?
The measure was a response to the HMRC’s own 2022 guidance, which brought up a few problems that are addressed in the current rule change.
Many stakeholders had expressed concerns that the 2022 guidance had produced disproportionate administrative burdens. The tax authority asked for a call for evidence and consultation for amendments.
The 2022 consultation brought to the fore the need for the alignment of taxation with the economic substance by not considering crypto used in DeFi lending and liquidity pool arrangements as a taxable disposal. The summary of the responses was published by the HMRC at the 2025 Budget.
The current framework is easier to understand and benefits the users, the HMRC assured investors. The current UK tax regime looks at crypto as an investment asset, with selling, exchanging, and spending, which is considered a disposal for CGT at 18% for basic-rate and 24% for higher-rate taxpayers. The new approach modifies this disposal treatment for certain lending and liquidity pool arrangements.
The measure’s final costing still needs certification by the Office for Budget Responsibility, and it will not come into effect until April 2027, giving UK crypto users and the protocols competing for them close to a year to adjust to the new amendment.
Supporting Measures by the HMRC
The tax reforms are just one of the areas the HMRC is working on. The tax authority has largely been focusing on crypto transparency through reporting measures based on the OECD Cryptoasset Reporting Framework (CARF).
Under these guidelines, it becomes mandatory for crypto platforms to share customer information directly with tax authorities. The information asked may contain account details, transaction history, asset balances, and trading activity.
These reporting guidelines are aimed at improving the tax compliance levels and decreasing the risk of undeclared crypto activity within the UK. The situation is a win-win situation for both investors and the HMRC, as investors find more favorable DeFi tax treatment, while the HMRC gains greater visibility into crypto transactions.
Conclusion
HMRC’s new liquidity pool tax amendment points to a major shift in how the UK looks at DeFi transactions. By doing away with the “dry tax” approach for a “no-gain, no-loss” framework, the government is aligning crypto taxation effectively with the actual economics of DeFi investing.
As the changes are a year away from implementation, investors who are looking for clear and more practical crypto tax rules in the UK will welcome the amendments when they finally come into effect on April 6, 2027.
