UK defers crypto capital gains tax to 2027 for DeFi deposits

1. HMRC announced that crypto deposits into DeFi lending protocols and liquidity pools will no longer trigger an immediate capital gains tax event, deferring any CG‑tax until a genuine economic disposal occurs, with the rule taking effect on 6 April 2027【1】.

At a glance

Policy shift and its mechanics

The new “no gain, no loss” (NGNL) rule replaces the 2022 guidance that treated moving tokens into a DeFi contract as a taxable disposal. Under the NGNL framework, lending a single cryptoasset, borrowing against it, or supplying tokens to an automated market maker (AMM) will not generate a tax event when the user enters or exits the arrangement with the same asset. A gain or loss is only recognised on an actual disposal—selling the asset, swapping it for another, or withdrawing more (or fewer) tokens than originally deposited【1】.

HMRC estimates the change will impact roughly 700,000 UK crypto users and trustees who currently engage in DeFi loans or liquidity provision【1】. The measure also aligns tax liability with the economic reality of the transaction, addressing the “disproportionate administrative burden” highlighted in stakeholder feedback to the 2022 guidance【1】.

Industry response and broader context

DeFi builders welcomed the amendment. Stani Kulechov, founder of Aave, called the NGNL approach “the right direction,” noting that without it taxpayers would face paperwork for paper gains that never materialised【1】. Kulechov linked the decision to earlier industry influence on a £20,000 cap for stablecoin holdings, suggesting the sector’s growing policy maturity【1】.

The rule also dovetails with the UK’s broader crypto strategy. HMRC will still treat staking yields, mining rewards, airdrops, and other token‑based income as miscellaneous income subject to Income Tax of up to 45% in the year received【2】. Additionally, the agency plans to enforce strict transaction‑tracking under the OECD’s Crypto‑Asset Reporting Framework (CARF) from 2027, ensuring compliance while the NGNL rule reduces paperwork for DeFi participants【2】.

What to watch

• April 6 2027 – Implementation date for the NGNL rule; platforms will need to update compliance systems.
• HMRC cost certification – Final cost assessment by the Office for Budget Responsibility could affect future refinements.
• CARF reporting rollout – Adoption of the OECD reporting framework may introduce new data‑submission requirements for crypto platforms.

The deferment signals the UK’s effort to balance a competitive crypto environment with tax compliance, but the ultimate impact will depend on how effectively platforms integrate the new reporting standards and whether the anticipated paperwork relief materialises for the estimated 700,000 users.
