First what is a Stablecoin?
There is a specific type of asset designed to stay as steady as the cash in your pocket. These are called stablecoins, and they are currently at the center of a major policy shift in the UK.
As an example if Bitcoin is like digital gold, stablecoins are like digital dollars or digital pounds. Assets like USDC or USDT are designed to be "pegged" 1:1 to a sovereign currency, usually the US Dollar. They aren't meant for "mooning" or speculation; they are built to be a secure, liquid way to save, pay, and earn on-chain without the price swings of traditional cryptocurrencies.
Anyone with a Revolut account in the UK will notice some recent changes namely the pound-pegged stablecoin. As of May 2026, Revolut is one of four firms selected for the Financial Conduct Authority's (FCA) Stablecoins Regulatory Sandbox, which allows for testing of digital assets in a controlled, "real-world" environment.
Why This Matters to Everyone (The "Tax Trap")
Currently, HMRC does not recognize stablecoins as "money". Instead, they are treated as property, meaning every single time you use them, you might be triggering a Capital Gains Tax (CGT) event.
- The Daily Friction: If you pay for a coffee with USDC, pay a teammate, or settle a business invoice, you are "disposing" of an asset in the eyes of the law, which requires a tax calculation.
- The "Invisible" Profit: Because tax law measures everything against the British Pound (GBP), you can be "sleepwalking into a tax trap". For example, if the Pound drops in value while you are holding stablecoins, your "digital dollars" are suddenly worth more in GBP terms. HMRC sees this as a "gain" you must pay for, even if your actual balance hasn't changed.
HMRC is Asking for Our Help
In a rare move, HMRC is proactively seeking evidence from the market on how to reform these rules. They are considering founder-friendly options, such as full tax exemptions that would treat stablecoins like the cash you hold in a bank account, or a "de minimis" threshold so small daily payments don't need to be reported.
This is a critical moment for the UK to build a "smarter tax design" that actually encourages innovation rather than stifling it with paperwork.
HMRC is actually being helpful here
Worth saying explicitly because it's easy to miss: HMRC is the only major tax administration globally that's proactively trying to reform stablecoin taxation.
They're not raising new taxes through this CFE, they're exploring whether to remove tax burden, not add to it.
The options on the table look genuinely founder-friendly:
- A new exemption that gives stablecoins similar treatment to cash held in a bank account
- A de minimis threshold so low-value retail payments don't need reporting
- Treating stablecoins as money for the purposes of the loan relationship rules
- Aligning interest-like returns from stablecoin lending with actual interest treatment
The deadline to submit evidence to HMRC is 7 May 2026. If the industry does not provide concrete, sensible feedback, the new rules will be drafted by people who don't have to live with the consequences.
