UK to defer Capital Gains Tax on qualifying crypto lending and liquidity pools from 2027

The UK government has unveiled plans to defer Capital Gains Tax [CGT] on certain crypto asset lending and liquidity pool transactions. It marks a significant change to how digital asset users are taxed.

Under a new HM Revenue & Customs [HMRC] policy paper published on July 13, qualifying cryptoasset loans and liquidity pool arrangements will generally be treated on a “no gain, no loss” [NGNL] basis. 

Instead of triggering CGT when cryptoassets are lent or deposited into eligible liquidity pools, tax will typically be deferred until the assets are economically disposed of. The measure is scheduled to take effect from April 6, 2027.

HMRC aims to align tax with economic activity

According to the policy paper, the measure is intended to better align the tax treatment of cryptoasset lending and liquidity pool arrangements with their underlying economic substance.

HMRC said the new framework will treat certain disposals involving crypto asset loans and liquidity pools as “no gain, no loss”. 

This means gains and losses will generally be recognized only when participants dispose of crypto assets, rather than when they enter qualifying lending or liquidity pool arrangements.

The proposal covers three types of arrangements:

• Single Crypto asset Lending Arrangements;
• Single Crypto asset Borrowing Arrangements; and
• Automated Market Making [AMM] arrangements, including qualifying liquidity pools.

For AMM arrangements, individuals exchanging crypto assets for liquidity pool interests will generally qualify for NGNL treatment. Any gain or loss will arise only where the quantity of crypto assets received differs from the amount originally invested.

Changes follow years of industry consultation

The policy follows several years of consultation between HMRC and industry participants.

HMRC said feedback on its 2022 guidance highlighted that the existing interpretation of the tax rules created disproportionate administrative burdens for participants in crypto asset lending and liquidity pools. 

That feedback led to a call for evidence in 2022. This was a formal consultation in 2023 and continued engagement with stakeholders before the government finalized its proposed approach.

The department estimates the measure will affect around 700,000 individuals involved in crypto asset loan and liquidity pool transactions. It said those taxpayers will benefit from a framework that is easier to understand and more closely reflects the economic substance of these arrangements.

Reform forms part of broader UK digital asset strategy

The tax changes come as the UK continues to update its regulatory framework for digital assets and tokenized finance.

Unlike a tax exemption, the proposal does not remove Capital Gains Tax obligations. Instead, it changes when gains or losses are recognized. This reduces situations in which tax liabilities arise before participants make an economic disposal of their crypto assets.

HMRC said the legislation will amend the Taxation of Chargeable Gains Act 1992 and will apply from April 6, 2027, giving affected taxpayers and service providers time to prepare for the new framework.
