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.

Three things changed, and all of them point in the same direction.

CARF took effect on January 1, 2026. The Cryptoasset Reporting Framework is an OECD standard that more than 50 jurisdictions have committed to, and the UK implemented it through HMRC's CARF legislation. UK-based reporting cryptoasset service providers must now collect identifying information from every user, including your National Insurance number, and report your transaction data to HMRC. Providers must register with HMRC by January 31, 2027, and file their first reports between January 1 and May 31, 2027, covering the calendar year January 1 to December 31, 2026. Penalties run up to £300 per user for reports that are late, inaccurate, incomplete, or unverified. That £300 penalty also applies to individuals who do not give their service provider the information it asks for.

CARF does not create a new tax. It closes the gap between what you report and what HMRC can check.

The Self Assessment form now has a dedicated cryptoassets section. Crypto disposals get their own boxes on the SA108 capital gains summary rather than being grouped under "Other property, assets and gains." HMRC can now see crypto as a separate asset class across the whole filing population.

HMRC published its first cryptoasset statistics on August 27, 2026. For the 2024/25 tax year, 17,600 individuals reported capital gains tax-liable cryptoasset disposals, with £13.8 billion in disposal proceeds and £1.38 billion in gains. HMRC's own Treasury estimate is that CARF will recover up to £315 million in unpaid tax by April 2030, which tells you how large the agency believes the reporting gap currently is.

If you have undeclared crypto gains or income from earlier years, HMRC runs a Cryptoasset Disclosure Service for voluntary disclosure. Coming forward before HMRC contacts you results in materially lower penalties than waiting for a prompted enquiry. Current-year and prior-year amounts should normally go on your Self Assessment return instead.

You owe capital gains tax if your total gains for the tax year, after allowable costs and losses, exceed the £3,000 annual exempt amount. Most individual investors land here.

You owe income tax if you receive tokens as income, which covers employment rewards, mining, staking, lending returns, and airdrops received in exchange for a service or action. National Insurance may also apply, depending on whether the activity counts as employment or trading.

You can offset allowable losses against gains in the same tax year, and unused losses carry forward indefinitely once you report them. Losses must be claimed within four years of the end of the tax year in which they arose.

Separating investment activity from income activity in your records from the start makes filing straightforward and makes it much easier to apply reliefs correctly.

Capital gains tax on crypto is 18% on the part of the gain that falls within your remaining basic rate band, and 24% on anything above it. Those rates have applied to most assets since October 30, 2024, and they are unchanged for 2026/27.

Your gain stacks on top of your taxable income, so your effective rate depends on what you earn. If you have a £40,000 salary and the higher rate threshold is £50,270, you have £10,270 left in the basic rate band. The first £10,270 of your taxable gain is charged at 18% and everything above that at 24%. A single gain is routinely split across both rates.

Crypto income is taxed at your income tax band in the year you receive it: 20%, 40%, or 45% in England, Wales, and Northern Ireland. When you later dispose of those tokens, capital gains tax applies to any increase in value between the amount taxed at receipt and the disposal proceeds. Two taxable events, two calculations.

A disposal includes selling crypto for fiat, swapping one token for another, spending tokens on goods or services, and gifting tokens to anyone other than a spouse or civil partner. On each disposal, you compare what you received with your allowable costs.

Gifts between spouses and civil partners are treated as no gain, no loss. Nothing is taxable at the point of transfer, and the recipient takes over your original base cost. Couples use this to move assets to the lower-earning partner before a sale, or to use two £3,000 allowances instead of one.

Allowable costs include what you paid for the tokens, transaction fees directly connected to acquiring or disposing of them, and the relevant share of your Section 104 pooled cost. Losses reduce gains in the same year, and any unused balance carries forward once reported. Every figure must be in pound sterling, converted at the time of the transaction using a valuation method you apply consistently.

Capital gains tax free allowance

The annual exempt amount is £3,000 for individuals and £1,500 for trusts. Gains within the allowance are tax-free, and gains above it are taxed at 18% or 24%. The allowance was £12,300 in 2022/23 and £6,000 in 2023/24, so investors who sat comfortably under the threshold a few years ago are often well over it now, even with the same volume of activity.

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 18% within any unused basic rate band and 24% above it. Those rates have applied since October 30, 2024. How much basic rate band you have left depends on your other taxable income: the personal allowance is £12,570, and the basic rate band covers the next £37,700, putting the higher rate threshold at £50,270.

Residential property rates were aligned with other assets at 18% and 24% in October 2024, and from April 6, 2026, carried interest sits entirely within the income tax framework. Neither affects a typical crypto disposal.

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 software-generated trade report along with their pooling and matching calculations.

You need to file and report crypto disposals if your total gains exceed the £3,000 annual exempt amount, or if your total disposal proceeds exceed £50,000 even when your net gain is below the allowance or you made a loss. Crypto disposals go in the dedicated cryptoassets section of the SA108, not in "Other property, assets and gains."

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, as 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 audit purposes.

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

TokenTax supports average cost basis accounting for UK filers, so your Section 104 pools are maintained automatically as you import transactions. One pool per token has to span every wallet and exchange, recalculate on every buy and sell, and apply the same-day and 30-day matching rules first. That is where manual spreadsheets break.

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 accurately compute any subsequent capital gain.

For England, Wales, and Northern Ireland, income tax is 20% on taxable income from £12,571 to £50,270, 40% on taxable income from £50,271 to £125,140, and 45% on taxable income above £125,140. The personal allowance is £12,570 and tapers by £1 for every £2 of income over £100,000, disappearing entirely at £125,140.

Scotland has six bands, running from 19% to 48%, with its higher rate starting at £43,663 rather than £50,270. Scottish rates apply to your crypto income but not to your capital gains, which are charged at UK-wide rates. A large staking year raises your total income and can push more of your gains from 18% to 24% without you selling anything differently.

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 small profits rate is 19% on profits up to £50,000 and the main rate is 25% on profits above £250,000, with marginal relief between those limits.

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.
