You sell cryptoassets on an overseas exchange, move the cash to your UK bank account, and the transfer is held for source-of-funds checks. The tax position depends less on where the exchange sits than on what created the balance: a sale, swap, payment, staking reward or token receipt.
Remittance & Overseas: moving cryptoassets to your own wallet or bringing sale proceeds into the UK does not usually create a new UK tax charge by itself. Since 6 April 2025, the remittance basis has been replaced by the four-year FIG regime for qualifying new UK residents.
Moving your own crypto is usually not taxable
A transfer between two wallets that you control is normally not a disposal of cryptoassets, meaning an event where you give up one asset for cash, another token, goods, or services. Sending Bitcoin from an overseas exchange to a Ledger wallet, then to an exchange used in England, normally does not itself create Capital Gains Tax.
Use this transaction decision tree
| What happens? | Usually a disposal? | Record needed |
|---|
| Wallet A to Wallet B, both yours | No | Addresses and transaction hash |
| Bitcoin sold for GBP or USD | Yes | Sale value, cost and fees in GBP |
| Bitcoin swapped for USDC | Yes | GBP value of Bitcoin at the swap |
| Crypto card pays a merchant | Usually yes | Card statement and token disposal value |
| Fiat sale proceeds sent to UK bank | Sale happened earlier | Exchange and bank trail |
Stablecoins are still cryptoassets
USDC is generally a cryptoasset, not cash, for UK Capital Gains Tax purposes, so a BTC-to-USDC swap can create a gain or loss.
FIG replaced remittance basis from 6 April 2025
Since 6 April 2025, eligible new UK residents can claim the four-year FIG regime, which can exempt qualifying foreign income and gains for their first four UK tax-resident years. Tax residence usually matters more than where an overseas exchange is based.
Who can use the FIG regime?
The four-year FIG regime is available only to an individual who becomes UK tax resident after at least 10 consecutive UK tax years of non-residence.
Historic claims need separate treatment
Where a valid claim is made, qualifying foreign income and gains arising in the first four UK-resident tax years can generally be relieved, whether they remain abroad or are brought to the UK. This is different from the former remittance basis, under which the remittance of foreign income and gains could be central to the tax result.
The regime does not make every crypto transaction tax-free: UK-source income, UK gains and disposals that fall outside the relief still need separate analysis. For years ending on or before 5 April 2025, historic remittance-basis rules and any mixed-fund position must be reviewed under the rules then in force.
Cashing out abroad still needs an evidence trail
A legitimate cash-out can still trigger a bank review. A UK bank may ask for source-of-funds evidence under the Money Laundering, Terrorist Financing and Transfer of Funds Regulations 2017, even where the transfer itself creates no extra tax charge.
Keep the chain from purchase to bank
- Save CSV exports from every exchange before an account is closed.
- Keep wallet addresses and transaction hashes for transfers between platforms.
- Record the GBP value, date, token amount and fees for every disposal.
- Keep purchase confirmations to support cost basis and HMRC share pooling rules.
- Keep bank statements and an explanation of the source of funds.
Include fees and exchange rates
Record GBP exchange rates and fees consistently.

For an overseas crypto exchange cash-out, document each operational step as well as the tax calculation. A USDC balance may need to be swapped into GBP or another fiat currency, transferred through an on-ramp or off-ramp, and then paid to a UK bank; each provider may impose withdrawal limits, request refreshed KYC, or pause a transfer while source-of-funds checks are completed. Network fees, trading fees and conversion spreads should be retained with the transaction records, and values should be translated using a consistent GBP exchange rate at the relevant disposal time.
Do not assume that a stablecoin transfer is equivalent to moving cash: a stablecoin swap or sale can itself be a cryptoasset disposal, even where the eventual bank transfer is routine.
Calculate the gain before sending funds to England
Calculate the gain at the disposal date, not when money later reaches England. For most individual investors, the basic calculation is sale proceeds in GBP less allowable cost and directly related fees, subject to the same-day rule, the 30-day bed and breakfast rule, and share pooling rules.
A short cross-border example
An individual buys 1 BTC for £20,000, swaps it for £45,000 of USDC, then withdraws £44,800 after fees. The taxable disposal is normally the BTC-to-USDC swap, with a starting gain of about £25,000 before allowable costs.
This guide is not enough if you are a trust beneficiary, partner, company director, professional trader, historic remittance-basis claimant, FIG claimant, or have mixed funds. Seek tailored UK tax advice where sanctions, DeFi lending, derivatives, a bridge, an airdrop, mining income, liquidity pools, or an overseas entity is involved.
The taxable point is not determined solely by a crypto cash-out. Staking rewards are commonly taxable as income when received, with their GBP value potentially becoming the acquisition cost for a later disposal. Frequent trading can create multiple Capital Gains Tax calculations, while an airdrop may have an income-tax treatment where received in return for services or an activity. Moving tokens through a bridge between wallets you control may not itself be a disposal, but receiving a different token or wrapped asset can require careful analysis.
Paying a supplier, friend or merchant in crypto is normally a disposal at the GBP value of what is provided. Keep separate records for each event before remitting any resulting fiat funds to the UK.
Questions & answers
Can I transfer crypto to the UK tax-free?
Sending crypto between wallets you control is normally not taxable in the UK. Tax may arise if you sold, swapped, spent, or received the crypto before that transfer.
Do I pay UK tax when I cash out crypto?
You may pay UK tax when you sell crypto for fiat, even if the cash stays abroad. A UK resident usually calculates the gain in GBP on the sale date, then reports it through Self Assessment where required.
Can HMRC see my overseas crypto?
HMRC can obtain data from exchanges, banks, and international reporting channels where the law allows. Accurate records are safer than relying on an overseas platform’s location.
Does the remittance basis still apply to crypto?
The remittance basis does not generally apply to new tax years from 6 April 2025. Eligible new UK residents may instead claim FIG relief for up to four tax years, subject to the 10-year non-residence condition.
What matters most:- Moving your own tokens is usually not a taxable disposal, but selling or swapping them often is.
- Stablecoins are cryptoassets, so a BTC-to-USDC exchange can create a taxable gain.
- For post-5 April 2025 years, check FIG eligibility rather than relying on old remittance-basis articles.
- Keep a full route from original purchase to UK bank receipt to support both HMRC reporting and AML checks.
