UK HMRC adopts “no gain, no loss” tax treatment for crypto loans from

The United Kingdom’s tax authority announced that from 6 April 2027 capital gains tax on crypto‑asset loans and liquidity‑pool participation will be deferred until an “economic disposal” occurs, applying a “no gain, no loss” rule to roughly 700,000 individuals and trustees【2】.

Policy details

HMRC’s new approach treats the acquisition or disposal of an interest in a crypto‑lending arrangement as a “no gain, no loss” event, meaning gains and losses are only recognised when the underlying crypto is actually sold or otherwise economically disposed of【4】. The same logic applies to borrowing arrangements—borrowed crypto is valued at market price at the time of borrowing, with any collateral ignored for CGT purposes【4】. For automated market‑making (AMM) pools, users acquiring an interest in exchange for the same type of crypto also receive the deferred treatment, aligning the tax outcome with the economics of the transaction【4】.

Market impact

Analysts expect the deferral to reduce the immediate tax burden on DeFi participants, potentially encouraging greater activity in UK crypto markets【1】. By postponing CGT that currently sits between 18 % and 24 % for the 2025‑26 tax year, the rule could improve net returns for investors who keep assets locked in lending or liquidity pools for extended periods【2】. The policy aligns UK tax treatment with traditional finance principles, a shift that may attract more institutional and retail participants to the domestic crypto ecosystem【1】.

What to watch

• Regulatory follow‑ups – Any further HMRC guidance on the definition of “economic disposal” could affect how quickly deferred taxes become payable.
• DeFi activity levels – On‑chain metrics such as total value locked in UK‑based lending platforms may rise if the tax advantage spurs new participation.
• Future tax reforms – Potential adjustments to the 2027‑28 tax year rates or extensions of the “no gain, no loss” rule to other crypto activities.

The move signals a clear intent by UK regulators to integrate crypto‑asset activities into existing financial frameworks, but the real test will be whether the deferred tax treatment translates into measurable growth in DeFi participation and whether future guidance clarifies the disposal trigger.
