UK HMRC unveils new crypto lending taxes

TLDR

UK tax authority HMRC has set out new crypto lending and liquidity pool tax rules that defer many capital gains until you actually exit a position, from April 6, 2027.

1. HMRC is amending UK capital gains law to give no gain, no loss treatment to specified crypto lending, borrowing and liquidity pool transactions.
2. For affected users, most DeFi-style token movements inside loans or pools will no longer create immediate capital gains tax calculations, cutting admin load but not eliminating tax.
3. These rules sit inside a wider UK crypto roadmap, so further detail on income from yields and more complex DeFi structures is likely over the next few years.

Deep Dive

1. Key Changes In Law

On July 13, 2026 HMRC published new UK crypto lending tax rules covering crypto asset loans and liquidity pools, effective from April 6, 2027.

They amend the Taxation of Chargeable Gains Act 1992 to introduce no gain, no loss (NGNL) treatment for certain transactions, meaning no immediate capital gain or loss is recognized at that point.

NGNL applies to single asset lending, single crypto asset borrowing, and automated market making via smart-contract liquidity pools when you move into and out of positions in the same asset type or quantity.

Confidence: high, based on HMRCs published rules dated 13 Jul 2026.

2. Impact On Crypto Users

Under the new regime, many internal movements of tokens inside lending and AMM arrangements are treated as non-taxable steps for capital gains; tax crystallizes when you later sell or otherwise dispose of the asset economically.

1. Single asset lending: acquiring or disposing of an interest in the same asset type is NGNL, so you do not compute CGT on entering or exiting the loan itself.
2. Borrowing: borrowed assets are treated as acquired at market value, and posted collateral is disregarded for capital gains while the borrowing is in place.
3. Liquidity pools: deposits and withdrawals of the same quantity of an asset into an AMM contract are NGNL; capital gains apply only if the quantity coming out differs from what went in.

HMRC explicitly frames this as a response to earlier guidance that forced users to track gains on non?economic events, aiming to simplify compliance for an estimated 700,000 people.

3. Broader Regulatory Context

These rules follow a structured process: a call for evidence in 2022, consultation in 2023, and a Budget 2025 summary, all within the UKs wider crypto regulation roadmap.

HMRC does not expect a significant macroeconomic impact or direct business costs; the focus is on individuals and trustees using asset loans and pools.

Separately, UK authorities are pushing tokenization and digital markets reforms, suggesting more detailed treatment of DeFi, staking and other crypto activities is likely as the framework matures.

Conclusion

HMRCs new NGNL treatment for crypto lending and liquidity pools is a technical but important shift: it moves UK tax rules closer to the economic reality of DeFi by taxing true exits rather than every internal token movement.

For crypto users, the main takeaway is less capital gains friction on routine lending and LP activity, while actual disposals and any taxable income remain in scope under existing rules.
