Cryptocurrency is now a routine part of many families' wealth, and HMRC has made clear that it expects it to be reported properly. The tax is not complicated in principle, but the records and the rules for matching purchases and sales are exacting. Mistakes are common, especially where trades run into the hundreds, or you have used several platforms.
We give Private Families practical, plain-English crypto tax advice, led personally by a Chartered Tax Adviser.
Who this is for
- Investors who have bought, sold or swapped crypto
- People who earn crypto through staking, mining, lending or work
- Families holding crypto in more than one wallet or exchange
- Anyone who has received a letter from HMRC about crypto

- Those moving countries with crypto assets
How crypto is taxed in the UK
HMRC treats cryptoassets as property. The result is two main charges.
Capital gains tax. A disposal occurs when you sell for pounds, exchange one token for another, spend crypto, or give it away. Gifts to a spouse or civil partner are not chargeable. Gains are taxed at 18% or 24%, after the £3,000 annual exempt amount for 2026/27.
Income tax. Crypto you receive as pay is taxed, with National Insurance, like any other earnings. Rewards from staking, mining and lending are generally taxed as income when received (or as trading income if the activity is a trade). When you later sell those tokens, capital gains tax applies only to growth since receipt.
For the capital gains calculation, tokens of the same type are pooled and the average cost is used. Two rules take priority: purchases on the same day as a sale, and purchases within 30 days afterwards. This is where spreadsheets often go wrong.
What has changed: HMRC now sees more
From 1 January 2026, UK crypto service providers must collect identifying information from users, including residence and tax identifiers. That information goes to HMRC under the Cryptoasset Reporting Framework, with the first annual reports due by 31 May 2027. Similar rules apply internationally. The practical effect is that HMRC can compare platform data to your tax return.
This is a sensible moment to get your records in order. If you have not reported before, a voluntary correction is better than a discovery. Our HMRC Enquiries page explains how that process works.
Crypto and the wider family picture
Crypto rarely sits on its own. It touches several other parts of a family's tax position:
- Spouses and civil partners. Gifts between them are not chargeable, so ownership can be rebalanced to use two annual exempt amounts and two basic rate bands. The transfer must be a genuine gift.
- Children. A gift of crypto to a child is a disposal at market value for capital gains tax, and a potentially exempt transfer for inheritance tax.
- Estates. Crypto is part of your estate. If your executors cannot find the wallets or keys, the value can be lost, so secure access instructions are part of good planning.
- Residence. Becoming non-resident changes the tax on future disposals, but timing around departure needs care. See our Residency page.
- Income and gains together. Rewards taxed as income, then sold later, create two layers of records and two calculations.
Planning across these areas is where specialist crypto advice adds more than a spreadsheet does.
Common mistakes
- Treating a swap from one token to another as tax-free
- Assuming transfers between wallets are disposals, or ignoring the fees on them
- Using exchange summaries as the tax calculation
- Missing the 30-day and same-day rules
- Failing to record the pound value of staking rewards at receipt
- Not reporting losses, which are then unavailable
- Forgetting crypto when planning inheritance tax
Reporting and records
Crypto disposals are reported on the cryptoasset section of the Self Assessment return, available from 2024/25, or through HMRC's real-time capital gains service. You need pool-by-pool records showing each acquisition, disposal, sterling value and running balance. Our Self-Assessment service covers the return, and our Capital Gains Tax Advice page covers planning around larger disposals.
Income, trading or investing?
Most individuals who buy and hold are investors, so their sales are capital gains. Someone who trades frequently, with a business-like approach, may be treated as carrying on a trade, which changes the rules: profits are income, and different reliefs and National Insurance considerations apply. HMRC looks at the whole pattern: frequency, organisation, intention and use of borrowed money. We review which side of the line you fall on, because the answer affects the rate, the records and the risk.
For small amounts of other crypto income there is a combined £1,000 allowance for trading and miscellaneous income. Between £1,000 and £2,500 of miscellaneous income you should contact HMRC, and above £2,500 you need to register for self-assessment.

Questions, answered.
Straight answers to what clients ask us most. Your own situation may differ, so treat them as a starting point.
Q1Do I pay tax on cryptocurrency in the UK?
Yes, in most cases. HMRC treats cryptoassets as property, not currency. You may owe capital gains tax when you sell, swap, spend or give away crypto at a gain, and income tax on crypto you receive as pay, or from mining, staking or lending. Simply buying and holding is not a taxable event, but the records start from the day you buy.
Q2Which crypto transactions trigger capital gains tax?
A disposal does. That covers selling for pounds, exchanging one token for another, using tokens to pay for goods or services, and giving tokens away. Gifts to a spouse or civil partner, or to a charity, are not chargeable. Transferring your own coins between your own wallets is not a disposal, but the fees and the record trail still matter.
Q3How is the gain on crypto calculated?
For each type of token, HMRC expects a pool containing the total number of tokens and the total cost. When you sell, you deduct a proportionate share of the pool cost from the proceeds. Two matching rules come first: tokens bought the same day as a sale, then tokens bought in the 30 days after a sale. Allowable costs include fees and the pooled cost, but not costs already deducted for income tax.
Q4What is the 30-day rule for crypto?
If you buy the same type of token within 30 days after selling it, that purchase is matched to the sale rather than going into the pool. The gain is then the sale proceeds less the cost of the repurchased tokens. It stops people selling to bank a loss and buying straight back. Frequent traders and bots can trigger it many times a year.
Q5Is staking or mining crypto taxed as income?
Rewards from staking, mining and lending are generally taxed as income at the value in pounds when you receive them, and outside a trade they are treated as other taxable income. If the activity amounts to a trade, trading profits rules apply instead. When you later sell the tokens, capital gains tax applies only to the growth since you received them, so you need the receipt value recorded.
Q6What about airdrops, forks and NFTs?
The treatment depends on how you came to have them. An airdrop received for doing something, or as part of a trade, can be income. One received with no action may be treated differently. Forks, NFT sales and DeFi arrangements each have their own rules in HMRC's cryptoassets guidance. We look at what you actually did before deciding how each item is reported.
Q7Do I need to report crypto if I made a loss?
Yes, it is worth doing. A loss can be set against gains in the same year and carried forward, but you must report it to HMRC within four years of the end of the tax year to claim it. The cryptoasset section of the Self Assessment return is available from the 2024/25 tax year onwards. Unreported losses are often lost for good.
Q8What is the capital gains tax allowance for crypto in 2026/27?
Crypto gains are added to your other gains. For 2026/27 the first £3,000 of total gains is tax-free for an individual. Above that, gains are taxed at 18% to the extent they fall within your unused basic rate band and at 24% beyond it. The allowance covers all assets together, so shares and property sales use it up too.
Q9What records do I need for crypto tax?
For each token type keep every transaction: the date, the number of tokens, the pound value at the time, fees, what you got in exchange and which wallet or exchange was involved, plus the pool balance before and after. HMRC says exchange reports help but are not tax calculations. If you have used several platforms or self-custody wallets, you need a combined record.
Q10What has changed with crypto reporting since January 2026?
Since 1 January 2026, UK crypto platforms must collect details such as your name, address, date of birth, country of residence and tax identifiers. That data goes to HMRC under the Cryptoasset Reporting Framework, and the first yearly report is due by 31 May 2027. In practice HMRC will be able to match platform records to your tax return far more easily.
Q11I have never declared my crypto. What should I do?
Do not wait for HMRC to write to you. Telling HMRC voluntarily, before they approach you, normally leads to lower penalties than being found. HMRC has a route for telling it about unpaid crypto tax. We reconstruct your transactions, calculate the tax and interest for each year, and prepare the disclosure. See our HMRC Enquiries page for how penalties are set.
Q12What is an HMRC nudge letter about crypto?
It is a letter, or email, that HMRC sends to people it thinks may have crypto tax to declare, often based on data from exchanges. It is not an enquiry and does not allege wrongdoing, but it asks you to review your position and correct any errors. Ignoring it can lead to a formal compliance check. Please do not respond with guesses before checking the facts.
Q13Can I give crypto to my children without paying tax?
A gift to a child is a disposal at market value, so a gain can arise even though no money changes hands. A gift to a spouse or civil partner is not chargeable. For inheritance tax, crypto forms part of your estate, and a lifetime gift is a potentially exempt transfer if you survive seven years. We plan the order and timing with the wider family picture.
Q14How is crypto treated when I die?
It is part of the estate and may be subject to inheritance tax at 40% above the available thresholds. Executors need to find and value it, which is hard without wallet keys and records. The assets pass to executors at market value at death for capital gains tax. Leaving clear, secure instructions for access is an important part of planning.
Q15Does moving abroad change how my crypto is taxed?
It can. If you become non-resident, UK capital gains tax on crypto generally stops, but gains on assets held before leaving can be taxed if you return within five years, and other countries may tax you. The timing of a disposal relative to your residence status is crucial, so we review it before you sell, not after.
Q16Can ASWATAX help if my records are incomplete?
Yes. We rebuild transaction history from exchange exports, wallet data and bank statements, then prepare the calculations HMRC expects. Where information cannot be recovered, we agree a reasonable basis and document it. Putting records in order is also the first step if you are considering a voluntary disclosure or have received a letter from HMRC.
