If you are planning to transfer Bitcoin, Ethereum or other crypto to someone else, it is vital to understand how crypto gift tax UK rules work. Many people assume a gift is not taxable because no money changed hands, but HMRC does not look at it that way in most cases. In the UK, giving away crypto can count as a disposal, which means Capital Gains Tax may apply even when you received nothing in return.
That is why crypto gift tax UK is an important topic for anyone moving assets to a partner, helping a child get started with investing, or donating tokens to a good cause. One wrong assumption can leave you with an unexpected tax bill, poor records, or a Self Assessment problem later on.

What counts as a gift of crypto?
For crypto gift tax UK purposes, a gift usually means you transfer beneficial ownership of the asset to another person and no longer control it. That might be sending crypto from your wallet to theirs, transferring it through an exchange account, or giving someone access in a way that genuinely makes them the owner. HMRC’s crypto guidance makes clear that giving away tokens to another person is generally treated as a disposal for Capital Gains Tax purposes.
So if you bought tokens cheaply and gift them when they are worth much more, HMRC may still tax the gain as though you had disposed of them at market value. That is the trap at the centre of crypto gift tax UK. The gift feels personal, but the tax treatment can be very businesslike.

Do you pay tax when you gift crypto?
Usually, yes, crypto gift tax UK rules mean a gift to someone other than your spouse or civil partner is potentially taxable. HMRC says that when tokens are given away to another person who is not your spouse or civil partner, you must work out the pound sterling value of what was given away. For Capital Gains Tax purposes, you are treated as receiving that sterling value even if you did not actually receive anything.
That means your gain is broadly based on:
Market value of the crypto on the date of the gift
minus
Allowable cost and any allowable fees
If the gain pushes you above your annual Capital Gains Tax allowance, tax may be due. For the 2025 to 2026 tax year, the annual exempt amount for individuals is £3,000. HMRC’s current CGT guidance also shows the main rates are generally 18% and 24%, depending on your tax position.
Is gifting crypto to your spouse taxed?
This is where crypto gift tax UK gets more interesting. HMRC guidance says giving away tokens to your spouse or civil partner is generally not treated the same way as gifting to other people. GOV.UK states that giving away crypto to your spouse or civil partner is an exception to the normal disposal treatment in this context, and gifts to a spouse or charity are also listed by GOV.UK as situations where you do not usually pay Capital Gains Tax.
That can make spouse transfers a legitimate planning point for couples, especially where one partner has unused annual allowance or falls into a lower tax band. Still, crypto gift tax UK planning between spouses should be documented properly. You need clear records showing what was transferred, when it was transferred, and the value at the time.
What about gifting crypto to your children or friends?
This is the area where crypto gift tax UK catches people out most often. A gift to an adult child, sibling, friend or unmarried partner will generally be treated as a disposal at market value. So even if you were simply being generous, you may still need to calculate and report a gain.
Example:
You bought crypto for £2,000.
By the time you gift it to your son, it is worth £8,000.
HMRC may treat that as a disposal worth £8,000, leaving a gain of £6,000 before any allowable deductions or losses.
That is why crypto gift tax UK is not really about whether money changed hands. It is about whether a disposal took place and what the asset was worth at that moment.
Is donating crypto to charity different?
Yes, but with an important wrinkle. GOV.UK says you do not usually pay Capital Gains Tax on gifts to a charity. However, HMRC also says cryptoassets are not considered money for Gift Aid purposes. So if you donate crypto directly, the charity generally cannot claim Gift Aid on that crypto donation. HMRC’s charity guidance says crypto must be converted into money before a donation can qualify for Gift Aid under the usual rules.
That means crypto gift tax UK for charity donations has two separate layers:
- The CGT treatment may be favourable.
- Gift Aid usually will not apply unless the crypto is first converted to cash.
What records should you keep?
Good record keeping is essential for crypto gift tax UK. You should keep:
- the date of the gift
- the type and quantity of tokens transferred
- the GBP market value at the time
- wallet addresses or exchange evidence
- who received the gift
- your original acquisition cost and fees
If you are already in Self Assessment, HMRC says you may need to report gains even if no tax is due where your disposal proceeds are above the reporting threshold. GOV.UK says that if your total gains are under the allowance, you still need to report them in your tax return if the total amount you sold assets for was more than £50,000 for tax years from 2023 to 2024 onwards.
Common crypto gift tax mistakes
A lot of crypto gift tax UK errors come from simple misunderstandings:
- assuming a gift is tax-free because it was not a sale
- forgetting that gifts to children or friends can trigger CGT
- failing to value the asset in pounds on the date of transfer
- confusing spouse transfers with all family transfers
- assuming Gift Aid applies automatically to direct crypto donations
These mistakes are easy to make, especially if you use multiple wallets or exchanges. HMRC’s wider crypto guidance has also been updated in recent years, and the government has moved ahead with international cryptoasset reporting rules designed to give tax authorities more visibility into users and transactions.
Final thoughts on crypto gift tax UK
The main lesson with crypto gift tax UK is simple: a gift can still be taxable. In many cases, HMRC treats gifting crypto as a disposal, which means you may need to calculate a gain using the token’s market value at the time of the transfer. Gifts to a spouse, civil partner or charity can be different, but they are not a free-for-all and still need proper records and careful handling.
If you have gifted crypto, are planning to transfer assets to family, or want to tidy up your records before filing, getting advice early can save a lot of stress later. Crypto gift tax UK is one of those topics that looks simple on the surface, then turns into a tax bramble patch the moment real money is involved.
