Guide to Crypto Taxes in the United Kingdom for 2026

Crypto is treated as an asset, not money, for tax purposes in the UK. For most individual investors, selling, swapping, spending, or gifting crypto (except to a spouse or civil partner) is considered a disposal and subject to capital gains tax.

You must calculate a gain or loss in pound sterling each time you dispose of tokens, even if no cash changes hands, for example when you trade one token for another or spend crypto on goods or services.

Income events are handled differently. Receiving crypto from employment, mining, staking, lending, or other activities can create income tax and may also create National Insurance liability. HMRC uses share-like rules for cost basis and matching, which means accurate records and GBP valuations are essential.

You may owe capital gains tax if your total gains, after allowable costs and losses, exceed the annual capital gains allowance. Most individual investors fall under CGT on disposals, while income-type receipts are taxed under income tax when received.

You owe income tax if you receive tokens as income, including employment rewards, mining, staking, or lending returns. You can usually offset allowable losses against gains for CGT, and unused reported losses can carry forward to future years. Good record-keeping and clear separation of investment activity from income activity make filing simpler and help you use reliefs correctly.

Capital gains tax uses two rates, a lower rate applied within any unused basic rate band and a higher rate above it. Your effective rate depends on your other income and how much of your basic rate band remains available in the tax year. If part of your gain sits within the basic rate band and part exceeds it, your gain can be split and taxed at both CGT rates.

Income you receive in crypto is taxed at your income tax bands in the year you receive it. Later, when you dispose of those tokens, CGT may apply to any increase in value from the amount taxed at receipt to the disposal proceeds. This two-step treatment is common for employment rewards and some forms of staking or lending returns.

A disposal includes selling for fiat, swapping one token for another, spending tokens on goods or services, or gifting to anyone other than a spouse or civil partner. You calculate a gain or loss on each disposal by comparing what you received with your allowable costs. If you gift to a spouse or civil partner, there is usually no gain and no loss at the time of transfer, and the recipient takes over your base cost.

Allowable costs include acquisition costs, certain transaction fees, and a proportion of your pooled cost for that token. Losses can offset gains in the same year. If total allowable losses exceed gains, you can carry forward the unused balance once you report it. Maintain all figures in pound sterling using a consistent valuation approach.

Capital gains tax free allowance

Individuals have an annual capital gains allowance. Gains above the allowance are taxed at your applicable CGT rates, and gains within the allowance are tax-free. Trusts have a smaller allowance and should check the current threshold each year.

The allowance resets each tax year. Losses reduce gains before the allowance is applied, so accurate loss reporting helps you use the allowance efficiently rather than wasting it against gains that could have been offset.

Start by identifying each disposal, then compare disposal proceeds with allowable costs and the relevant share of your Section 104 pooled cost. If you acquired and disposed of the same token on the same day, or disposed and re-acquired it within 30 days, special matching rules apply before you use the pooled cost.

If your tokens become worthless or untradeable while you still own them, you may be able to crystallize a loss using a negligible value claim. Theft itself is not a disposal, but in some cases a negligible value claim may still be available. Keep evidence for all claims, including exchange records and wallet activity.

CGT on most assets, including crypto, is charged at a lower rate within any unused basic rate band and a higher rate above it. How much of your basic rate band remains depends on your other taxable income and the personal allowance you are entitled to in that year.

Residential property and carried interest follow different CGT rules and rates, which are outside the scope of this crypto guide. If you have mixed gains in a year, you may see different rates applied to different assets.

You must keep detailed records for every transaction, but you do not have to type each trade into the return. On Self Assessment you report totals and include computations, and HMRC can request your detailed schedules if needed. Many filers attach a trade report generated by software along with their pooling and matching calculations.

Your records should include dates and times, token types, quantities, GBP values, fees, wallet addresses, and exchange identifiers. Consistent GBP valuation at the time of each transaction is vital, since HMRC expects your pooling and matching to be calculated in pound sterling.

The UK tax year runs from April 6th to April 5th. If you need to file for the first time, register for Self Assessment by October 5th following the end of the tax year. Paper returns are due by October 31st following the end of the tax year. Online returns and any balancing payment are due by January 31st.

Some taxpayers also make Payments on Account on January 31st and July 31st. Most people report crypto gains and losses through Self Assessment. UK residential property has its own in-year CGT reporting, which is separate and not relevant to typical crypto disposals. Interest and penalties can apply if you file or pay late, so plan ahead and choose a payment method that clears on time.

Gifting crypto to a spouse or civil partner is generally no gain, no loss for CGT, so there is no immediate tax. The recipient inherits your base cost and will calculate CGT only when they dispose of the asset. This can be a useful way to rebalance holdings or to use multiple allowances within a household.

Gifts to anyone else are disposals by the donor at market value on the date of the gift. Donations to qualifying UK charities are usually exempt from CGT, subject to conditions. Keep a record of the market value and the reason for the valuation you used.

Use one Section 104 pool per token. Each acquisition increases the pooled units and pooled cost, and each disposal reduces them proportionally. The pool tracks average cost over time and must be maintained in pound sterling, even if your exchange reports in another currency.

Before you use the pool, apply matching in this order: same-day acquisitions, acquisitions within the next 30 days, then the Section 104 pool. These rules prevent bed-and-breakfasting and apply to crypto just as they do to shares. Keep separate pools for each token across all wallets and exchanges.

HMRC uses average cost within each Section 104 pool, adjusted for every buy and sell. Fees that directly relate to acquiring or disposing of tokens are usually allowable costs and should be included in your pool. Fees for transfers between your own wallets are not disposals but should still be recorded for auditability.

Keep complete documentation for your methodology, including price sources and time stamps for valuations. Consistency matters, since HMRC expects you to apply the same approach throughout the year and across all accounts.

How to report crypto taxes to HMRC

Most people report via Self Assessment, using the main return with Capital Gains pages and attaching computations. If you do not otherwise need to file a full return, you can use the real-time CGT service to report certain gains during the year.

The online Self Assessment includes dedicated questions for crypto assets. Keep your detailed calculations and records in case HMRC asks for them during a compliance check.

How to pay tax on cryptocurrency to HMRC

You can pay by online banking, Direct Debit, or card. If paying close to a deadline, choose a same-day method and allow for bank processing times.

Many taxpayers must also make Payments on Account on January 31st and July 31st if their income tax liability meets HMRC thresholds. Set reminders so you do not miss these instalments.

Tokens you receive from employment, crypto mining, staking crypto, lending, or similar activities are generally taxable as income when received. Whether this is trading income or miscellaneous income depends on scale, organization, and commerciality. National Insurance may also apply depending on your circumstances.

When you later dispose of those tokens, capital gains tax may apply to any increase in value between the amount taxed at receipt and the disposal proceeds. Keep the GBP value at receipt as your crypto cost basis so you can compute any later capital gain accurately.

Income tax uses bands commonly called basic, higher, and additional rates, and a personal allowance that may taper as income rises above a threshold. Your income tax position for the year determines how much basic rate band remains available for CGT at the lower rate.

Scotland sets different bands and rates from the rest of the UK. If you receive crypto as income, be sure to account for that in your band usage, since it can push more of your capital gains into the higher CGT rate.

DeFi returns can be taxed as income or as capital depending on the facts. Key factors include whether you gave up beneficial ownership, how the return is realized, and whether you receive periodic payments or a capital amount from disposing of an asset or right.

If a platform pays you periodic rewards directly, that often looks like income. If your return arises from selling or redeeming a capital asset, that often looks like capital. Review each arrangement carefully and keep documentation of the terms to support your position.

You can claim a crypto capital loss for tokens that became worthless or of negligible value while you owned them. HMRC treats this as a disposal and reacquisition at negligible value on the claim date, which crystallizes the loss for CGT purposes. Keep evidence such as exchange delistings, market data, and wallet records.

Theft is not itself a disposal, so you cannot usually claim a CGT loss for stolen tokens. In some cases a negligible value claim may still be possible if recovery is clearly impossible and other conditions are met. Maintain documentation for any claim you make.

Companies are taxed on profits under Corporation Tax rules, which include trading profits and chargeable gains on tokens. The rate you pay depends on your level of profits, with a small profits rate at the low end, a main rate at the high end, and marginal relief in between.

Business receipts of tokens can be trading income, miscellaneous income, or capital, depending on your activities and how tokens are used or disposed of. Maintain robust accounting policies and documentation so tax and financial reporting remain aligned.

Keep complete records for each transaction and each token pool, including dates and times, token types, quantities, GBP values, fees, wallets, exchange identifiers, and TX hashes where available. Save exchange statements and export your activity regularly, since some platforms limit historical access.

Use a consistent methodology for GBP valuations, and write it down. Good records are essential to apply the same-day, 30-day, and pooling rules correctly and to support any claims you make for losses or reliefs.
