TLDR
The UK proposed a no gain, no loss tax treatment for DeFi lending and liquidity pools, deferring capital gains until an actual disposal (sale or swap) occurs per HMRCs plan (no gain, no loss).
- Depositing tokens into DeFi lending or liquidity pools would not trigger capital gains at deposit (proposal details).
- Applies to lending, borrowing and AMMs; gains/losses calculated on withdrawal by comparing tokens returned vs supplied (scope and mechanics).
- It is a proposal under consultation, not law yet, with timing still unconfirmed (status update).
Deep Dive
1. No Gain, No Loss
HMRCs proposal would align DeFi taxation with economic reality by deferring capital gains tax until a true disposal (for example, selling or swapping), rather than taxing mere token movements into protocols. This removes dry tax events at deposit and simplifies record?keeping for users (HMRC position summary).
If you add collateral or supply liquidity without selling, you wouldnt face an immediate capital gains bill. Tax would arise later when you actually dispose of the asset.
2. Scope And Mechanics
The framework covers common DeFi actions and clarifies how to compute gains or losses at exit (proposal details):
- Lending/borrowing and single?token arrangements: deposits and withdrawals treated no gain, no loss until disposal.
- AMMs and multi?token pools: tax calculated when you redeem, based on the difference between tokens returned and those originally supplied (mechanics).
- Borrowing cycles: tax computed only on the difference between what was borrowed and repaid, not on locking collateral.
Record the quantities you supply and later receive back; the taxable result depends on that difference, not on the act of depositing.
3. Status And Next Steps
This is not enacted yet. HMRC has been consulting for over two years and published a summary noting 32 detailed responses from industry and tax experts. The new approach has broad support, but legislative timing is unresolved (consultation update).
Treat this as a likely direction of travel, but wait for formal legislation before assuming the rules apply to current tax years.
Conclusion
HMRCs no gain, no loss proposal would remove capital gains tax at deposit for DeFi activities and shift tax to genuine disposals, reducing dry tax and compliance burden (overview). If enacted, it could improve clarity for UK DeFi users and may influence other jurisdictions, but the final scope and timeline remain pending (status).
