To sell Bitcoin in the UK, use an FCA-registered exchange (Coinbase UK, Kraken, or Bitstamp) that allows GBP withdrawals, convert your BTC to GBP on the exchange, withdraw to your UK bank account via Faster Payments or CHAPS within 1–3 business days, and report the transaction to HMRC. Selling Bitcoin is a capital gains tax event; you must calculate your gain (sale price minus cost basis) and keep records of the date, amount sold, and GBP value at the time of sale. Bitcoin ATMs exist but charge 5–10% spreads and are suitable only as a last resort. This is information, not financial advice.
Step 1: Choose an FCA-regulated exchange that serves the UK
Selling Bitcoin in the UK means converting it back to GBP on an exchange that is permitted to serve UK clients. The FCA register lists authorised firms; the most accessible to UK buyers and sellers are Coinbase UK (registered), Kraken (registered), and Bitstamp (registered). Each allows GBP deposits and withdrawals to UK bank accounts.
On the FCA register, search for the firm's legal name. A crypto exchange must either hold a cryptoasset exchange licence (if offering services to consumers) or be registered as a Money Transmitter for fiat withdrawal services. Verify the exchange's own terms confirm it serves your region and the sale direction you want.
- Coinbase UK — US-headquartered, long-established, offers GBP trading pairs and Faster Payments withdrawal.
- Kraken — US-headquartered, supports GBP pairs and Faster Payments; also holds MiCA CASP in Ireland and Luxembourg.
- Bitstamp — oldest European exchange, Luxembourg-based, supports GBP withdrawal and holds MiCA CASP in Luxembourg.
Step 2: Convert Bitcoin to GBP on the exchange
Log into your account on your chosen exchange, navigate to the trading or 'convert' section, and select Bitcoin (BTC) as the asset you wish to sell and GBP as the fiat currency. The exchange will show the current BTC/GBP price and any trading fee (typically 0.1–0.5% of the sale amount). Review the total GBP amount you will receive and confirm the transaction.
Write down or screenshot the date, time, the amount of Bitcoin sold, the GBP price per Bitcoin, and the total GBP received. This is your record of the sale for tax purposes. Some exchanges also offer 'Instant Sell' or 'Quick Sell' buttons for immediate conversion; these may incur a slightly higher fee but execute quickly.
Step 3: Withdraw to your UK bank account
Once your Bitcoin has been converted to GBP on the exchange, you can withdraw the funds to your UK bank account. Most UK exchanges offer Faster Payments (typically 1 business day) or CHAPS (same-day for larger amounts, with higher fees). Select your registered UK bank account from the withdrawal list, enter the amount, and confirm.
The exchange will transmit the GBP to your bank via the Faster Payments or CHAPS system. Expect the funds to arrive within 1–3 business days, depending on your bank and the transmission method. Once in your account, the funds are yours to use or save as you wish.
UK capital gains tax on Bitcoin sales
Selling Bitcoin is a taxable 'disposal' event under UK capital gains tax (CGT). You must calculate your gain or loss: sale price in GBP minus the cost basis (what you originally paid for the Bitcoin plus any transaction fees at purchase). If you sold for a gain, that gain is subject to capital gains tax; if you sold for a loss, the loss can offset other capital gains in the same tax year.
HMRC requires you to report all cryptoasset disposals on your tax return. You must keep records of the date you sold, the amount sold, the price per unit in GBP at the time of sale, and the cost basis of the Bitcoin you sold. The annual exempt amount (AEA) for CGT is a fixed threshold; you pay tax only on gains above that amount. Check the current HMRC guidance for the current tax year's AEA — it changes annually and you should never rely on a figure stated here.
If you sold Bitcoin at a loss, you can use that loss to offset other capital gains. If you made multiple sales in the same year, you must calculate the total gain or loss across all disposals. Professional or 'trading' levels of buying and selling may trigger income tax rather than capital gains tax, which is a higher rate; consult a tax adviser if you are unsure whether your activity is viewed as trading.
Record-keeping and reporting to HMRC
Keep a spreadsheet or record book of every Bitcoin purchase and sale. For each sale, record: (1) the date sold, (2) the quantity of Bitcoin sold, (3) the GBP price per Bitcoin at the time of sale, (4) the total GBP proceeds, (5) the original purchase date and cost per Bitcoin (your cost basis), and (6) the calculated gain or loss. Save receipts from the exchange showing the sale and withdrawal.
When you complete your Self Assessment tax return, you will declare all capital gains from all sources, including cryptoasset disposals. HMRC uses the data submitted by exchanges to cross-check — some UK exchanges are required to report transactions, and HMRC monitors for under-reporting. Failing to report a capital gain is a breach of tax law and can result in penalties and interest.
If your total taxable gain in the year exceeds the annual exempt amount, you will owe CGT at the rate applicable to your tax band (usually 10% for basic-rate taxpayers, 20% for higher-rate taxpayers). File your return on time and pay any tax due by the deadline (usually 31 January after the end of the tax year) to avoid penalties.
Alternatives: Bitcoin ATMs, P2P and other methods
Bitcoin ATMs and physical kiosks exist across the UK and can convert Bitcoin to cash or GBP. However, they typically charge 5–10% spreads (fees on top of the market price), making them far more expensive than using an exchange. They may also require identity verification under anti-money laundering rules. Use a Bitcoin ATM only if you cannot access an exchange, or for a small amount where convenience outweighs cost.
Peer-to-peer (P2P) platforms like LocalBitcoins alternatives allow you to sell Bitcoin directly to another person in exchange for cash or bank transfer. P2P sales carry higher counterparty risk — the buyer may default or dispute the transaction — and you will still owe capital gains tax on the transaction. P2P is suitable for small, informal amounts only; for most UK sellers, an exchange is safer and clearer for tax purposes.
Frequently asked questions
How long does it take to sell Bitcoin and withdraw to my UK bank account?
Converting Bitcoin to GBP on an exchange is immediate (seconds to minutes). Withdrawing GBP to your UK bank account via Faster Payments typically takes 1 business day; CHAPS can be same-day but may incur higher fees. Total time is usually 1–3 business days from sale to funds in your account. Bank processing times vary; allow extra time if the sale is near a weekend or bank holiday.
Do I pay capital gains tax if I sell Bitcoin in the UK?
Yes. Selling Bitcoin is a capital gains tax event in the UK. You must calculate your gain (sale price in GBP minus your cost basis) and report it to HMRC. You owe capital gains tax on gains above the annual exempt amount. Even if you sell at a loss, you should report the loss to offset other gains. Failing to report is a tax breach. Consult a tax adviser if you are unsure about your position. This is information, not financial advice.
What is the cost basis for capital gains tax?
Cost basis is what you originally paid for the Bitcoin you sold, including any transaction or exchange fees incurred at purchase. For example, if you bought 1 BTC at £25,000 and paid a £25 fee, your cost basis is £25,025. Your capital gain or loss is the sale price minus the cost basis. If you bought Bitcoin at different times, HMRC allows you to use average cost, specific identification, or first-in-first-out (FIFO) methods to calculate which Bitcoin you sold. Keep purchase receipts to prove your cost basis.
Which UK exchanges can I sell Bitcoin from?
FCA-registered exchanges that serve the UK and support GBP withdrawals include Coinbase UK, Kraken, and Bitstamp. Search the FCA register (at register.fca.org.uk) for the exchange's legal entity name to verify its status. Some global exchanges do not serve UK clients under current rules; always check the exchange's own terms to confirm it accepts new UK users. This is information, not financial advice.
Is selling Bitcoin via a Bitcoin ATM safe and tax-compliant?
Bitcoin ATMs are physical kiosks that convert Bitcoin to cash or bank transfer. They are legal in the UK but charge 5–10% spreads, making them much more expensive than exchanges. You remain liable for capital gains tax on any sale via a Bitcoin ATM; the high fees do not reduce your tax bill. Use a Bitcoin ATM only if you cannot access an exchange, for small amounts where convenience outweighs cost. This is information, not financial advice.
What happens if I sell Bitcoin but don't tell HMRC?
Failing to report a capital gain to HMRC is a tax breach. Exchanges are required to report transactions, and HMRC uses this data to identify under-reporting. Penalties for non-compliance include interest on unpaid tax and additional penalties ranging from 20% to 100% of the tax due, depending on whether the failure was careless or deliberate. It is far cheaper and safer to file correctly and on time. Consult a tax adviser if you need help.
Can I offset a Bitcoin sale loss against other capital gains?
Yes. If you sold Bitcoin at a loss, you can use that loss to offset other capital gains you made in the same tax year, reducing your overall CGT bill. If the loss is larger than your other gains, you can carry the unused loss forward to future tax years to offset future gains. Report losses on your Self Assessment tax return even if you do not owe tax, to preserve the carry-forward right. This is information, not financial advice.
Is selling Bitcoin to another person the same as selling on an exchange for tax purposes?
No difference for tax purposes. Whether you sell via an exchange, P2P platform, or directly to another person, the sale is a taxable disposal event and you owe capital gains tax on any gain. You must calculate and report it to HMRC the same way. The transaction type does not change your tax obligation, only the method and speed of conversion and withdrawal. This is information, not financial advice.
