UK HMRC Introduces 'No Gain/No Loss' Tax Treatment for Cryptoasset Lending and Liquidity Pools... A Major Turning Point for the DeFi Market

On July 13, 2026, the UK government released draft legislation ending the era of 'accidental' Capital Gains Tax for participants in cryptoasset lending and liquidity pools. Reflecting the economic substance of Decentralized Finance (DeFi), this reform adopts a 'No Gain, No Loss (NGNL)' framework, deferring tax liabilities until an actual economic disposal takes place.

This is the result of government consultations held since late 2025 and is part of a strategic move to propel the UK into a global cryptoasset hub. The measure is seen as removing one of the biggest points of tax friction faced by cryptoasset investors in the UK.

Marking what is known as 'Legislation Day 2026,' the UK Treasury unveiled new tax treatment policies for cryptoasset lending and liquidity pool transactions. This announcement is considered the most substantial package of cryptoasset tax reforms implemented by the UK to date and is expected to drastically reduce the tax reporting burden for investors.

This tax reform is a decisive step in enhancing the competitiveness of the UK cryptoasset market and is a huge victory for DeFi users as a prime example of reflecting the economic substance of cryptoassets in law.

Under the previous tax system, the act of a user depositing assets into a protocol for liquidity provision was often treated as a 'disposal' that triggered Capital Gains Tax. However, under the new NGNL approach, even if the legal ownership of the asset technically changes, no tax will be charged as long as the economic substance is maintained. Instead, tax charges are deferred until the point of 'economic disposal,' when the asset is actually sold on the market.

Strategic Background: The UK's Vision for a Global Crypto-Asset Hub

This tax reform aligns with the trend of strengthening crypto-asset regulations pursued by the UK Financial Conduct Authority (FCA) and the Treasury since early 2026. The UK government has clearly expressed its strategic intent to secure competitiveness in the global market by attracting foreign capital and innovative DeFi projects through the establishment of a clear and rational tax system.

• Crypto-asset lending and borrowing transactions within decentralized protocols
• Asset deposits for liquidity provision and the subsequent receipt of tokens/certificates
• DeFi activities where beneficial ownership is retained but technical ownership is transferred
• Other qualifying crypto-asset lending arrangements and collateral transactions as defined by HMRC

HM Revenue & Customs (HMRC) stated that these regulations primarily apply when a user remains exposed to the value fluctuations of an asset, even if the legal ownership of that asset is transferred to a smart contract. This is a rational approach that bridges the gap between the technical characteristics and economic substance of digital assets, reflecting long-standing demands from industry experts.

Although this draft legislation provides a definitive signal, it must pass through standard legislative procedures to be enacted into law. Investors should closely monitor the final version of the Finance Bill 2026 and the updated HMRC Cryptoassets Manual (CRYPTO61600) guidelines to assess the impact on their portfolios.

The industry anticipates that this measure will serve as a catalyst for increasing crypto-asset trading volume in the UK and lowering entry barriers for institutional investors. In particular, it will provide a strong incentive for individual investors who have hesitated to participate in DeFi due to complex tax calculations, which will serve as an opportunity to enhance the overall maturity of the UK's digital asset ecosystem.

In conclusion, the UK's tax reform demonstrates the government's progressive attitude toward embracing the dynamism of the crypto-asset market. These policy changes are expected to not only contribute to solidifying the UK's status as a global financial hub but also serve as an important milestone for other major economies in the process of establishing their own crypto-asset tax systems.
