How HMRC Classifies Crypto Assets
HMRC does not treat crypto as money. Learn the four token categories and why stablecoins are not currency.
How HMRC Classifies Crypto Assets
HMRC does not treat crypto assets as currency or money. They are treated as property for tax purposes. This distinction is fundamental — it means every transaction involving crypto assets can potentially be a taxable event.
The Four Token Types
HMRC recognises four types of crypto asset:
| Type | Definition | Tax Treatment |
|---|---|---|
| Exchange tokens | Used as a means of exchange (e.g. BTC, ETH, stablecoins) | CGT on disposal, Income Tax if trading |
| Utility tokens | Provide access to a product or service | CGT on disposal |
| Security tokens | Provide rights such as ownership, repayment, or share in profits | CGT on disposal, may also be subject to Stamp Duty |
| Stablecoins | Pegged to fiat currency or other assets | Same as exchange tokens — NOT treated as currency |
Stablecoins Are Not Currency
This is one of the most common misunderstandings. Stablecoins like USDT, USDC, and DAI are not treated as GBP or USD by HMRC. A swap from ETH to USDT is a disposal of ETH for Capital Gains Tax purposes, even though the user may perceive it as "cashing out to a stable value."
This means you cannot use a stablecoin as a "safe harbour" to defer tax. The moment you exchange any crypto asset for a stablecoin, you have made a disposal and must calculate your gain or loss.

Explain Like I'm 5
Imagine you have special trading cards. The government says those cards are not real money, even if some of them always seem to be worth the same as a pound coin. Every time you swap, sell, or give away one of your trading cards, the government might want to know about it. There are four kinds of cards, and none of them count as pocket money.
Key Takeaways
- HMRC treats all crypto assets as property, not currency.
- Four token types: exchange, utility, security, and stablecoins — each with specific tax treatment.
- Stablecoins (USDT, USDC, DAI) are NOT treated as GBP. Swapping to a stablecoin is a disposal.
- Every crypto transaction can potentially be a taxable event — there is no 'safe' token.
