Do You Pay Tax on Cryptocurrency in the UK?
Learn how HMRC taxes cryptocurrency disposals in the UK for the 2025/26 tax year, including the £3,000 tax-free allowance, CGT rates, and reporting deadlines.
Yes, you must pay tax when you sell cryptocurrency in the UK if your total net gains exceed your annual tax-free allowance. HM Revenue and Customs does not view cryptocurrency as money, meaning that most disposals are subject to Capital Gains Tax rather than Income Tax.
Key Takeaways: UK Crypto Tax at a Glance
Understanding your tax obligations is essential to avoid penalties. Under HM Revenue and Customs guidelines, key factors determine your liability for the 2025/26 tax year.
- You receive a tax-free Capital Gains Tax allowance of £3,000 for the 2025/26 tax year.

Do you pay tax on crypto in the UK?
Yes, you generally pay Capital Gains Tax when you dispose of cryptocurrency in the UK because HM Revenue and Customs classifies these digital assets as capital property.
HM Revenue and Customs does not classify cryptoassets as currency or money. Instead, the tax authority treats them as capital assets, meaning that when you sell, trade, or spend them, you are making a disposal for Capital Gains Tax purposes. If the value of your asset increased from the time you acquired it to the time you disposed of it, you have made a taxable gain.
How does the annual Tax-Free Allowance work?
You do not pay tax on capital gains that fall within your annual tax-free allowance, which is £3,000 for the 2025/26 tax year.
Every individual in the UK has a personal Capital Gains Tax allowance. For the 2025/26 tax year, this allowance is set at £3,000, meaning you only pay tax on profits that exceed this amount across all asset disposals in the year. If your total gains remain at or below £3,000, you will have no tax liability to pay on those specific gains.
What are the crypto tax rates for 2025/26?
Your Capital Gains Tax rate for crypto is either 18% or 24% depending on your total taxable income and tax band.
| Taxpayer Type | Total Income | CGT Rate on Crypto |
|---|---|---|
| Basic rate | Up to £50,270 | 18% |
| Higher rate | £50,271 to £125,140 | 24% |
| Additional rate | Over £125,140 | 24% |
Your capital gains are added to your other taxable income to determine which rate band applies. If the combined total pushes you over the basic rate threshold, the higher rate applies to the portion of the gain that sits in the higher band.
What counts as a taxable disposal of crypto?
A disposal occurs whenever you part with ownership of your crypto, which triggers a potential Capital Gains Tax calculation under HM Revenue and Customs rules.

- Swapping one type of cryptocurrency for another digital asset.
- Using cryptocurrency to pay for goods, services, or online purchases.
- Gifting crypto to other individuals, unless they are your spouse or civil partner.
When you do not need to pay crypto tax in the UK
You are not required to pay tax if your gains are within the annual limit, you make a loss, or you transfer assets internally.
- Your cumulative capital gains for the tax year remain within the £3,000 personal allowance.
- You make a capital loss, which can be claimed to offset other gains or carried forward.
- You transfer crypto assets directly between your own private digital wallets.
How to report and when to pay crypto tax in the UK

- Register for Self Assessment by 5 October 2026 if you have not filed a return before.

HMRC rule changes: The Cryptoasset Reporting Framework (CARF) in 2026
The implementation of the Cryptoasset Reporting Framework on 1 January 2026 means HM Revenue and Customs will receive automated transactional data.
Under the new Cryptoasset Reporting Framework, UK crypto exchanges and platforms must automatically share your transaction history with HM Revenue and Customs. Government estimates suggest this measure will help recover £80 million in unpaid taxes by the 2029/30 tax year. Because of this increased data sharing, keeping precise and accurate records of your transactions is vital.
Do you get taxed on crypto in the UK if you just hold it?
No, you do not pay any tax simply for holding cryptocurrency in your wallet. HM Revenue and Customs only charges Capital Gains Tax when you sell, trade, spend, or gift your crypto, which are classified as disposals.
How does a crypto tax UK calculator work for Capital Gains?
A crypto tax calculator automates your bookkeeping by tracking your original acquisition costs, applying specific matching rules like the share pooling rules, and subtracting those acquisition costs from your disposal proceeds to calculate your exact taxable gain.
Can I pool my crypto allowance with my spouse or partner?
You cannot combine your allowances into a single double-sized allowance, but you can transfer assets to your spouse or civil partner tax-free. Doing this allows both of you to utilise your individual £3,000 allowances when selling the assets.
How do I offset cryptocurrency losses on my UK tax return?
You can report your cryptocurrency losses on your Self Assessment return to reduce your overall capital gains for the year. If your losses exceed your gains, you can carry them forward to offset gains in future tax years.
