UK updates planned crypto lending and liquidity tax rules

What the October update adds

On 28 October 2026, HMRC updated its July proposal for cryptoasset loans and liquidity pools, including the treatment of Single Cryptoasset Lending Arrangements. The intended start date is 6 April 2027 for the relevant individual and trustee Capital Gains Tax rules. The central proposal is deferral in qualifying circumstances, not abolition of tax on all decentralised-finance activity. Official source.

Different arrangements need different treatment

The note distinguishes lending, borrowing and automated market-making arrangements. Certain exchanges involving the same asset type would be treated on a no-gain/no-loss basis. For qualifying liquidity arrangements, differences between quantities invested and returned can still produce a gain or loss. The updated official publication sets out these distinctions and the proposed changes.

Economic deferral is not a general exemption

A transaction may postpone recognition rather than eliminate it. What rights the participant acquires, which assets move and what comes back are important. Labels such as staking, lending or liquidity provision on a platform do not by themselves establish that the arrangement fits the proposed statutory category.

Reconstruct the transaction chain

Keep wallet and platform statements, transaction identifiers, asset quantities, valuations and the agreement or protocol terms used at the time. Where a token represents an interest in a pool, document that relationship rather than treating it as an unexplained deposit. These records help an adviser assess the actual arrangement and distinguish capital treatment from other tax questions.

Hypothetical example

An individual supplies two types of tokens to a liquidity arrangement and later receives different quantities of each. The proposal should not be reduced to “withdrawals are tax free”. The original contribution, the interest held and the quantities returned must be examined to determine whether the described deferral applies and whether a difference produces a gain or loss.

Check the rules applicable on the transaction date

The announced 2027 approach should not be applied automatically to a 2026 return. Existing transactions, future transactions and any relevant transition provisions need separate consideration under final legislation. The policy does not protect against platform failure, losses or defective contracts, and it is not a recommendation to enter a particular cryptoasset arrangement.
