Two rules and one exception. Gifting cryptoassets is a CGT disposal at market value, so you can owe tax on a gift. Transfers to a spouse or civil partner are no gain, no loss, which is the most useful planning tool in this whole subject. And spending crypto is also a disposal.
- Gift is a disposal?
- Yes — at market value
- Spouse / civil partner
- No gain, no loss
- Gift allowance for CGT
- None — check your annual exempt amount
- Recipient taxed on receipt?
- No
- Recipient base cost
- Market value at gift, or transferor's cost between spouses
- Spending crypto
- Yes — a disposal
Why gifting is a disposal
HMRC treats cryptoassets as property for capital gains purposes. A disposal includes selling, exchanging, using to pay for goods or services, and giving away. The fact that no money changed hands does not matter: you are treated as having disposed of the asset at its market value on the date of the gift.
The practical consequence catches people out:
| Step | Amount |
|---|---|
| You acquired the asset for | £4,000 |
| Market value on the day you gift it | £20,000 |
| Cash you received | £0 |
| Deemed disposal proceeds for CGT | £20,000 |
| Chargeable gain, before any allowance | £16,000 |

HMRC's own guidance is the authority here — see the cryptoassets manual collection and the general capital gains tax pages.
The spouse exception
This is the one genuinely valuable piece of planning in this subject, and it is unglamorous and entirely ordinary.
A transfer of an asset between spouses or civil partners who are living together is treated as no gain, no loss: you realise nothing on the transfer, and your partner acquires the asset at your original cost.
- Both partners have their own annual exempt amount, so a joint disposal can use two rather than one
- The asset can be moved to the lower-rate partner before a sale
- There is no value limit on the transfer itself
- The original acquisition cost is what carries over, so that figure is the critical record to keep
Two caveats worth stating. The exemption applies to spouses and civil partners — not unmarried partners, for whom a gift is an ordinary disposal. And the transfer needs to be genuine; an arrangement where an asset is transferred and immediately returned is not what the rule contemplates. Our spouse and family guide covers the practice.
The annual exempt amount
There is no separate gift allowance for capital gains purposes in the UK. What can cover a small gain is your annual exempt amount for CGT — the tax-free slice of total gains in a tax year.
That figure has been reduced substantially in recent years, which materially changes the arithmetic on modest gifts compared with older guidance still circulating online. Check the current amount on GOV.UK rather than relying on any article, including this one, and remember it covers all your gains for the year rather than each transaction separately.
Inheritance tax, briefly
Capital gains tax is not the only consideration on a large gift. Gifts can also be relevant for inheritance tax, where lifetime gifts may be brought back into an estate if the giver dies within seven years, subject to exemptions and taper relief.
- This is a separate regime from CGT, with its own exemptions and its own timeline
- It matters for substantial gifts and for estate planning rather than for a £200 birthday present
- Cryptoassets are property for these purposes like anything else
- Records of what was given, to whom and when are what make it manageable
See GOV.UK on inheritance tax, and take advice if the amounts are significant.
Records and reporting
- Record every acquisition Date, asset, quantity, cost in pounds, and the venue.
- Record every gift given Date, recipient, quantity, and market value in pounds on that date. A screenshot from the day is worth more than a later estimate.
- For spouse transfers, record the original cost That is the figure that carries over, and it is what your partner will need.
- Track pooled costs correctly UK CGT uses share-pooling rules for identical assets, which is why a running record matters more than individual receipts.
- Report through Self Assessment Using the capital gains pages, or the real-time service where applicable. Check current thresholds for when reporting is required.

The UK rule that trips people up is the one nobody expects: you can owe tax on a present. Somebody gifts a long-held asset to a sibling, receives nothing, and discovers a chargeable gain measured against a market value they never realised. It is not a loophole or a trap, it is simply how disposals are defined — and it is worth knowing before rather than after.
The corresponding good news is the spouse rule, which is the only piece of tax planning in this whole subject that I think everybody in scope should know. Two annual exemptions instead of one, and the ability to sell from whichever partner has the lower rate. Documented, ordinary, and almost never mentioned in crypto content.
