How is DeFi taxed in the UK?
In the UK, HMRC generally treats cryptoassets as subject to Capital Gains Tax on disposals and Income Tax on some rewards — with DeFi details evolving. Decentralized Finance Publication summarises themes: swaps and many DeFi exits can be disposals; staking or lending rewards may be income. Not tax advice — check HMRC manuals and a qualified adviser for your facts.

HMRC’s high-level stance (qualitative)
HMRC publishes cryptoasset manuals that discuss buying, selling, exchanging, and using tokens. In broad terms, disposing of a cryptoasset — including swapping one token for another — can crystallise a capital gain or loss. Simply buying crypto with GBP is typically not a disposal of the crypto itself.
HMRC has also issued materials on DeFi lending and staking, exploring when rewards are taxed as income and when lending or liquidity provision might be analysed as a disposal or a different arrangement. Guidance has been updated over time; always read the current HMRC pages rather than outdated threads.
Common DeFi activity themes
Token swaps on a DEX, repaying loans with different assets, and exiting LP positions often involve disposals for CGT purposes in HMRC’s framing. Reward tokens from farming or staking are frequently considered when received for Income Tax, with a later disposal potentially creating a capital gain — again depending on the facts and current guidance.
Record-keeping matters: dates, GBP values, wallet addresses, and transaction hashes help if you need to file Self Assessment. HMRC has increased data collection from UK-registered exchanges, so assuming activity is invisible is unwise.
Important limits of this page
Tax depends on your residency, the exact protocol mechanics, and whether you are trading as a business. Decentralized Finance Publication is not a firm of accountants; we do not calculate liabilities or file returns.
For decisions that affect your tax return, use official HMRC cryptoasset guidance and speak to a qualified UK tax adviser. Nothing on this page is tax, legal, or financial advice.
