HMRC has updated how it treats certain DeFi crypto transactions, shifting them to a “no gains, no loss” framework so Capital Gains Tax is deferred until a real disposal happens.
- CGT deferred: token movements into certain lending and liquidity pool structures are no longer taxed immediately
- Old guidance replaced: the criticized 2022 approach created “dry tax” headaches
- Income still taxed: staking rewards and similar receipts can still fall under income tax rules
- More reporting ahead: OECD CARF rules will expand transaction data collection
The new measure is called Tax treatment of cryptoasset loans and liquidity pools, and it does something long overdue. It stops pretending that every smart-contract movement is a sale. Under the new no gains, no loss (NGNL) rule, certain cryptoasset transfers into lending and liquidity pool arrangements are treated as tax-neutral until there is an economic disposal, in plain English, a real event where value is actually realized.
That matters because DeFi does not work like a normal brokerage account. Users deposit assets into smart contracts, receive claim rights or pool interests, borrow against positions, and move through chains of transactions without necessarily cashing out. The old 2022 guidance was widely criticized because it could create a tax bill even when no true gain had been realized. Critics called that a “dry tax” problem for a reason. It was tax on paper gains, not actual economic ones.
HMRC’s new approach brings the tax treatment closer to how these systems actually operate. For certain cryptoasset lending arrangements, borrowing arrangements, and automated market making structures, the taxable moment is pushed back until there is a genuine disposal. That means selling, swapping, or otherwise exiting the position in a way that creates a real gain or loss still matters. The bureaucratic nonsense is reduced. The taxman is not being sent packing.
One point that matters for readers: this is not a blanket DeFi tax holiday. It is a narrower rule for specific structures. In a lending arrangement, disposal of an interest can be treated on an NGNL basis when it relates to cryptoassets of the same type as the assets originally invested. In an automated market making arrangement, the disposal of an interest can also be NGNL when someone deposits crypto into a smart contract and receives an interest in return. If the participant later receives back more or less than the original quantity invested, a gain or loss can arise by reference to that difference.
HMRC has said the measure affects about 700, 000 individuals engaged in these cryptoasset loan and liquidity pool transactions, and it takes effect from 6 April 2027. That is not a tiny corner of the market. It is a serious slice of the UK’s crypto user base, which tells you this is a practical tax fix, not some theoretical policy footnote written for a committee room nap.
There is also a technical wrinkle around borrowing. HMRC’s framework treats borrowed cryptoassets as acquired at market value when borrowed, and returning the same type of crypto is treated as a disposal at that value. Collateral is disregarded for Capital Gains Tax purposes. That is a cleaner fit than the old approach, which too often treated ordinary protocol mechanics as if they were straightforward sales in a traditional market.
For readers less familiar with the jargon, a liquidity pool is a smart-contract pool of tokens used by decentralized exchanges and other DeFi platforms to make trading possible. Users who deposit assets into those pools provide liquidity and may receive fees or rewards in return. Under the new rule, the movement into the pool is not, by itself, the moment HMRC wants to tax as a capital gain.
But the other side of the ledger remains firmly in place. HMRC is not softening on income. Tokens received from staking can be taxed as miscellaneous income if the activity does not amount to a trade, and the general UK tax framework can treat other income-like receipts similarly depending on the facts. That can leave higher-rate taxpayers facing income tax of up to 45% in the year the income is received.
So yes, one headache gets smaller. Another one is still lurking with a clipboard.
The reporting side is where the next layer of friction appears. In November 2023, the UK committed to integrating the OECD’s Crypto-Asset Reporting Framework (CARF), a global standard that requires crypto service providers to collect and share transaction data with tax authorities. Under the UK timetable, reporting service providers are expected to start collecting CARF information from 1 January 2026, with first reports due by 31 May 2027.
That is the tradeoff in a nutshell. The UK is removing one awkward tax trap for legitimate DeFi users, but it is also tightening the reporting net. For users and platforms, that means fewer phantom capital gains on technical token movements, but more structured record-keeping and more visibility for HMRC.
HMRC says the new framework should reduce administrative burden and better reflect the economics of these arrangements. That part makes sense. Tax law should not punish people simply for using smart contracts instead of old-fashioned intermediaries. If a token is parked in a protocol, wrapped, pooled, or routed through a contract without a real sale, taxing it immediately was always a clumsy fit.
Still, this should not be mistaken for the UK rolling out a DeFi paradise. The tax rules are becoming more rational, but the surveillance layer is getting stronger. That is how governments usually operate when they decide they want innovation and traceability. Less nonsense, more paperwork. Progress, apparently, comes with forms.
The bigger signal here is that the UK is trying to make its crypto rules more workable without surrendering compliance. That may help the country remain a more sensible place to build and use DeFi infrastructure than jurisdictions that either over-tax everything or understand nothing. It is a limited but meaningful improvement, and in crypto taxation, limited improvements are often the best kind available.
Key questions and takeaways
-
What is HMRC changing?
HMRC is moving certain cryptoasset lending and liquidity pool arrangements to a “no gains, no loss” treatment, so Capital Gains Tax is deferred until there is a real disposal. -
When does the new rule start?
The measure takes effect on 6 April 2027. -
Who does it affect?
HMRC says about 700, 000 individuals engaged in cryptoasset loan and liquidity pool transactions are in scope. -
Does this make DeFi tax-free in the UK?
No. Real disposals can still trigger Capital Gains Tax, and staking rewards and similar receipts can still be taxed as income depending on the facts. -
What still gets taxed as income?
Staking rewards can be taxed as miscellaneous income if the activity is not a trade, and the broader UK tax system can also treat other income-like receipts similarly based on the circumstances. -
What is CARF?
CARF is the OECD’s Crypto-Asset Reporting Framework, a global reporting standard that requires crypto platforms to collect and share transaction data with tax authorities. -
When does CARF reporting begin?
UK reporting service providers are expected to start collecting CARF information from 1 January 2026, with first reports due by 31 May 2027. -
What is the practical takeaway for UK crypto users?
The UK is fixing one of the worst parts of DeFi taxation, but users should still track transactions carefully. The capital gains treatment is getting saner. The compliance regime is getting stricter.
HMRC’s shift is a welcome correction to a tax system that was trying to squeeze DeFi into a shape it was never built for. The rules are more realistic now, but the data trail is getting thicker. That is the deal: fewer phantom tax bills, more reporting, and less room for people to pretend decentralization means invisibility.
