This week, His Majesty’s Revenue and Customs (HMRC) unveiled a groundbreaking tax proposal supporting the "no gain, no loss" principle for crypto lending and liquidity pool arrangements. This initiative stands to fundamentally reshape how DeFi (Decentralized Finance) users in the UK are taxed.
Under the current system, DeFi users who deposit funds into a protocol—even if only to earn yield or use as collateral for a loan—may trigger capital gains tax. The new approach would defer taxation until there is a genuine, economically meaningful disposal of assets.
01 A Game-Changing Tax Framework
The UK government is developing a new tax framework that could deliver significant benefits for DeFi users.
According to this week’s proposal, HM Revenue & Customs now supports applying the "no gain, no loss" principle to crypto lending and liquidity pool arrangements.
The core of this policy lies in shifting the timing of tax liability.
Currently, when DeFi users deposit funds into a protocol—even if it’s just to earn yield or serve as collateral for a loan—they may incur capital gains tax.
The new proposal would postpone the tax point until assets are actually disposed of in an economically meaningful way, marking a fundamental shift in the UK’s approach to DeFi taxation.
02 From the Current System to New Rules
To appreciate the value of this tax reform, it’s essential to compare the current system with the proposed changes.
Issues with the Current Tax Regime
According to HMRC’s 2022 guidance, even temporarily transferring tokens into a liquidity pool or using them as collateral can be considered a "disposal" for capital gains tax purposes.
This means users simply participating in DeFi activities—such as depositing crypto into lending protocols or providing tokens to automated market makers—face immediate tax liabilities.
The system is clearly flawed: users are required to pay taxes on what may be temporary asset transfers, even if no real profit has been realized.
Key Advantages of the New Rules
The proposed "no gain, no loss" (NGNL) approach would delay the tax trigger until users actually realize gains or losses.
In practical terms, users who deposit crypto into lending protocols or provide tokens to automated market makers would no longer be taxed at the point of deposit.
Tax would only be due when they ultimately sell or trade the assets and realize a gain or loss.
This change aligns tax rules with the realities of DeFi operations, reducing administrative burdens and preventing unreasonable tax outcomes.
03 Tax Treatment in Complex Scenarios
The new tax principle applies not only to straightforward lending and deposit scenarios but also extends to more complex multi-token arrangements.
Under the proposal, if users withdraw more tokens than they originally deposited, the profit portion would be taxed; if they withdraw less, it would be treated as a loss.
This logic also applies to liquidity pool scenarios.
When users provide tokens to automated market makers, the act of depositing and withdrawing itself does not trigger a taxable event. Taxation is deferred until the user ultimately sells or trades the assets and realizes a gain or loss.
Cross-chain transactions are also under consideration.
Government responses indicate that complex scenarios—including wrapped tokens and multi-chain transactions—will be factored into policy development.
Wrapped tokens refer to tokens that represent the value of another token but exist on a different blockchain, allowing users to transact more flexibly across blockchains.
04 Industry Response and Policy Progress
The tax proposal has received a warm welcome and support from major players in the DeFi sector.
Aave founder Stani.eth noted that when users deposit assets into Aave, the deposit itself is not considered a capital gains tax disposal, thus establishing a "no gain, no loss" approach.
He praised the reform highly: "For UK DeFi users who want to borrow stablecoins using crypto as collateral, this is a major win."
He added: "We advocate for DeFi and ensure that tax treatment for interactions with lending protocols reflects economic reality: users borrowing against collateral to meet liquidity needs do not intend to dispose of their assets."
Policy Development Process
This reform concept did not emerge overnight. The UK government began gathering evidence in the summer of 2022, followed by a formal consultation from April to June 2023.
During the consultation, HMRC received 32 formal written responses from individuals, businesses, tax professionals, and representative bodies.
After the consultation, HMRC continued constructive informal engagement with advisors and industry participants to refine the rules.
Currently, the model has not been finalized, and the government is still consulting with professionals and DeFi developers.
While HM Revenue & Customs has not set a legislative timetable, it has indicated ongoing engagement with the industry to assess the need for legislation.
05 The UK’s Strategic Position and Global Impact
This tax reform is not an isolated event—it’s part of the UK’s broader strategy to build a comprehensive crypto regulatory framework.
Comparing Global Regulatory Models
The UK’s "no gain, no loss" framework stands in sharp contrast to regulatory approaches in the EU and the US.
The EU’s Markets in Crypto-Assets Regulation (MiCA), which will be fully implemented in December 2024, offers cross-border compliance advantages but lacks flexibility in its regulatory classifications.
The US regulatory environment is even more fragmented, with overlapping federal and state rules enforced by the Securities and Exchange Commission (SEC) and the Commodity Futures Trading Commission (CFTC).
The UK’s NGNL framework offers a middle ground: balancing innovation and consumer protection, avoiding the rigidity of the EU and the fragmentation of the US.
Supporting Measures and Market Impact
Beyond DeFi tax reform, the UK has expanded access to tax-advantaged crypto investment vehicles.
Starting October 2025, UK regulators will allow retail investors to purchase crypto exchange-traded notes (cETNs) through tax-advantaged accounts such as ISAs and pension plans.
These strategic moves send a clear signal: the UK is committed to establishing itself as a global center for crypto finance.
According to AInvest research, the UK blockchain technology market is expected to grow to $54.63 billion by 2033, highlighting the role of regulatory clarity in driving growth.
Greater tax certainty has already led to institutional crypto ETP inflows reaching €1.7 billion in 2025, reflecting growing confidence among traditional financial institutions in regulated crypto products.
06 Outlook and Challenges
While the UK government’s proposal has been widely praised, challenges remain.
Technical Details Await Clarification
The government still needs to determine how to apply the NGNL principle to complex DeFi arrangements such as yield farming and yield aggregators.
Yield farming refers to users depositing tokens earned from liquidity pools into separate protocols to compound returns.
Yield aggregators involve transferring tokens among various crypto lending and liquidity pool protocols, using pre-programmed and automated strategies to optimize returns.
The tax treatment details for these complex scenarios are yet to be finalized.
Preventing Abuse and Protecting System Integrity
The government must also ensure the new rules are not exploited and that the integrity of the tax system is maintained.
Some respondents have raised concerns about potential abuse and recommended that the rules include robust safeguards.
Uncertain Legislative Timeline
Although the proposal has gained support, the legislative timeline remains unclear.
HM Revenue & Customs has stated it will continue engaging with the industry to assess the need for legislation.
This means that final implementation may still be some time away.
Looking Ahead
For UK users engaging in DeFi activities on Gate, this tax reform promises to make participation in crypto lending, liquidity provision, and staking simpler and more aligned with economic reality.
Once the new rules take effect, users will no longer need to worry about triggering temporary capital gains tax obligations simply by participating in these activities. Tax will only be due when assets are ultimately sold at a profit or loss.
Although the model is not yet finalized, the proposal itself points to the future direction of DeFi taxation in the UK—tax rules will be aligned with the actual workings of DeFi, driving the UK forward in its goal to become a global crypto finance hub.
