Depositing into DeFi lending protocols or liquidity pools no longer triggers immediate capital gains tax.
Tax liability defers until a genuine economic disposal: a sale, a swap outside DeFi, or a fiat conversion.
CARF reporting from UK platforms to HMRC began on January 1, 2026, expanding surveillance alongside the relief.
HM Revenue and Customs (HMRC) confirmed on February 12, 2026, that the UK government is advancing a No Gain, No Loss, or NGNL, tax treatment for specific decentralized finance activities covering lending and liquidity provision.
The confirmation formalized a direction signaled in HMRC’s November 26, 2025, consultation outcome, which acknowledged that existing rules produced an outcome widely regarded as economically incoherent: users faced capital gains tax charges simply for depositing tokens into DeFi protocols and later withdrawing them, even when they received back the same assets with no genuine economic disposal having occurred.
Under the NGNL framework, transferring crypto assets into qualifying lending protocols or liquidity pools does not trigger a capital gains tax event.
The taxable disposal is deferred until a genuine economic event occurs: selling the asset, swapping it outside a DeFi context, or converting to fiat.
The UK joins a small group of jurisdictions that have formally aligned crypto tax treatment with the economic reality of DeFi participation rather than its mechanical form.
What Changes in Practice
The practical significance for DeFi users is substantial. Under the prior rules, a user depositing Ethereum into an Aave lending pool at one price and withdrawing it weeks later at a higher price faced a capital gains liability on that difference, even though they never sold a single token and remained fully exposed to ETH’s price movements throughout.
Repeating that across hundreds of DeFi interactions across a tax year produced compliance costs and tax liabilities that bore no relation to whether the user had actually profited in any economically meaningful sense.
The NGNL framework eliminates that phantom liability for qualifying transactions. Routine deposits into lending pools, withdrawals at redemption, and liquidity provision through automated market makers now carry neither gain nor loss at the point of movement.
The cost basis of the original position carries forward to the eventual genuine disposal, preserving the tax system’s ability to capture real economic gains while removing the administrative burden of treating every protocol interaction as a taxable event.
