Home / How to Cash Out Crypto
Arrange a FREE Consultation Call and Let’s Discuss Your Goals!
You can’t cash out all your crypto tax free in the UK, but you can often cash out a meaningful amount with little or no Capital Gains Tax. The £3,000 annual exempt amount, capital losses, spouse transfers and careful timing do most of the work.
This guide covers when HMRC taxes a crypto sale, what you’ll pay in 2026/27 and the legal ways to pay less. MMBA doesn’t buy, sell or exchange crypto. Our crypto tax accountant team handles the tax, accounting and audit side of it.
MMBA’s crypto team is led by Waqqas Memon and Danial Sajid.
You pay Capital Gains Tax when you dispose of crypto at a gain, not when you withdraw pounds to your bank. HMRC counts selling tokens, swapping them for another token, spending them and giving them away as disposals. Gifts to a spouse, civil partner or charity are the exceptions.
The table below shows how HMRC treats the most common actions.
| What you do | Taxable? | Which tax |
| Sell Bitcoin or Ethereum for pounds | Yes | Capital Gains Tax |
| Swap one token for another, including USDT or USDC | Yes | Capital Gains Tax |
| Spend crypto on goods or services | Yes | Capital Gains Tax |
| Pay an exchange or network fee in tokens | Yes, as a small disposal | Capital Gains Tax |
| Give crypto to a spouse or civil partner you live with | No | None at the time |
| Give crypto to a registered charity | No | None |
| Move crypto between wallets you control | No | None |
| Withdraw pounds from an exchange to your bank | No | None |
| Buy crypto and hold it | No | None |
| Receive staking, mining or lending rewards | Yes, when received | Income Tax |
Swaps catch most people out. Every token-to-token swap is a disposal, even if no pounds ever reach your bank.
The amount you withdraw isn’t the test. Your gain is. If you sell £10,000 of Bitcoin with a pooled cost of £7,000, your gain is £3,000, which the annual exempt amount covers. You can withdraw the full £10,000 with no Capital Gains Tax, provided you have no other gains that tax year.
Crypto gains are taxed at 18% within your basic rate band and 24% above it, on total gains over the £3,000 annual exempt amount. These rates have applied since 30 October 2024. The allowance was £12,300 as recently as 2022/23.
The rate you pay depends on your income, as the table below shows.
| Your Income Tax band | Capital Gains Tax rate on crypto |
| Gains that fit within your basic rate band | 18% |
| Gains above it (higher and additional rate) | 24% |
Your salary uses up the basic rate band first, so a large gain often falls partly in each band.
Here’s a worked example for a basic rate taxpayer in England. Sarah earns £40,000 and makes a £15,000 gain on Bitcoin in 2026/27. After her £3,000 allowance, £12,000 is taxable.
Splitting the sale into £7,500 gains across two tax years would give her two allowances and keep everything at 18%, assuming her salary and the £3,000 allowance stay the same next year. Her total bill would fall to £1,620, a saving of £643.80.
HMRC matches every sale in a fixed order, so you can’t pick which tokens you’re selling. The same day rule applies first, then the 30 day rule for tokens of the same type bought in the 30 days after the sale, then the Section 104 pool, which uses the average cost of everything else you hold.
The main legal methods are timing, losses, spouse transfers and claiming every allowable cost. None of them removes tax on a large gain, but together they can cut it a lot.
Not for coins you already own. HMRC doesn’t treat crypto as money, so it can’t be used for a tax-relieved pension contribution, and selling to fund an ISA or pension is itself a disposal. Since 6 April 2026, new crypto exchange-traded notes (ETNs) can only go into an Innovative Finance ISA, not a Stocks and Shares ISA. Our personal tax accountant team can explain how this affects your tax return.
It’s free of Capital Gains Tax, but HMRC says crypto donations aren’t eligible for Gift Aid. To claim Gift Aid, you’d need to sell first and donate the money, and that sale may be taxable.
Not if you come back within 5 years. HMRC’s temporary non-residence rules can tax gains made abroad in the year you return if you were UK resident in at least 4 of the 7 tax years before leaving. The Statutory Residence Test determines your status, and the remittance basis ended after 2024/25. Our offshore tax advice and planning team can review a planned move.
Since 1 January 2026, crypto platforms have collected user details under the Cryptoasset Reporting Framework (CARF), with first reports to HMRC due by 31 May 2027. CARF is an international standard, so HMRC also receives data on UK residents from providers in other participating countries.
Under CARF, UK cryptoasset service providers report to HMRC, and providers abroad that follow the same rules share UK users’ data too. Using an overseas exchange no longer keeps your activity out of view.
Sell on a platform registered with the Financial Conduct Authority (FCA), withdraw pounds to your bank and keep records of every step. The FCA says no crypto ATM operators are registered with it, so crypto ATMs in the UK are operating illegally. HMRC expects records of each token type, dates, amounts, value in pounds, bank statements and your pooled costs, and recommends keeping wallet addresses. The best crypto tax software can import exchange data and apply the matching rules.
You must report and pay if your total gains are above £3,000. If you already file Self Assessment, you also complete the capital gains pages when disposals were worth more than £50,000 or gains before losses topped £3,000.
Returns from 2024/25 onwards have a dedicated cryptoasset section. UK residents who don’t file Self Assessment can use HMRC’s real-time Capital Gains Tax service instead, reporting by 31 December and paying by 31 January after the tax year. First-time filers must register by 5 October.
As miscellaneous income, unless you’re trading. The £1,000 trading allowance covers small amounts. If your miscellaneous income is between £1,000 and £2,500, tell HMRC, and above £2,500, register for Self Assessment. The same rules cover lending and liquidity pool returns, which our DeFi tax UK guide explains.
A company pays Corporation Tax on its crypto gains, and a regulated crypto firm may also need an audit. Moving personal crypto into a company you control counts as a disposal at market value, because HMRC treats you as connected people. Our corporate tax accountants handle company crypto accounts and tax.
Cryptoasset businesses must already register with the FCA under the Money Laundering Regulations, and the FCA expects its cryptoasset regime to take effect on 25 October 2027. Our financial services audit team works with FCA-regulated firms, as our Wirex Limited case study shows.
We’re the accountants you speak to before and after a sale. We don’t trade, hold or move crypto, and we don’t recommend exchanges. Our crypto team, led by Waqqas Memon and Danial Sajid, helps in the following ways.

No. A gift to anyone other than your spouse, civil partner or a charity is a disposal at market value. You may owe Capital Gains Tax even though you received nothing, and the gift may count for Inheritance Tax if you die within 7 years.
HMRC doesn’t treat theft as a disposal, so you can’t claim a Capital Gains Tax loss. If tokens you received have since become worthless, a negligible value claim may be possible instead.
Usually not, unless you file a Self Assessment. Then you still report when disposals exceed £50,000 or gains before losses exceed £3,000. Reporting a loss is worth doing because you must claim it to use it later.
