Sending Bitcoin to a child, sibling or parent can create Capital Gains Tax before anyone sells a satoshi. The key point is Bitcoin's sterling market value when it leaves the donor's control. Cash for a child's own purchase creates a different record from gifting BTC already held.
Can I send bitcoin to family without UK tax?
You can send Bitcoin to family. Only qualifying transfers between spouses or civil partners living together normally avoid an immediate CGT calculation. Gifts to other relatives usually create a market-value disposal for the sender.
The family link alone does not remove Capital Gains Tax.
Which relatives get no-gain/no-loss treatment?
| Recipient | CGT result for sender | Recipient's starting cost |
|---|
| Spouse or civil partner, living together | Usually no gain/no loss | Usually carries over sender's pooled cost |
| Child or parent | Market-value disposal normally applies | Usually GBP market value on gift date |
| Sibling or other relative | Market-value disposal normally applies | Usually GBP market value on gift date |
The rules differ sharply between a spouse and every other relative.
Three common family examples
A gift to a child normally counts as a disposal at market value. The same rule normally applies to a parent, sibling, or other relative.
A gift to a spouse or civil partner can use no-gain/no-loss treatment. This normally applies only while the couple are living together.
A close family relationship does not create a general Bitcoin gift tax exemption.
Why bitcoin gifts use market value in GBP
For a non-spouse gift, HMRC normally uses Bitcoin's GBP market value on the transfer date. It does not use the original purchase price. The donor's gain is that value less the allowable pooled cost.
Use a reputable source showing BTC/GBP. Record the exact date and time. Save a screenshot or export from that source.
Use the same source for the donor and recipient. Your location within England does not change the sterling valuation.
For most non-spouse gifts, the donor's deemed sale value should match the recipient's acquisition cost. Both should use the BTC/GBP value at the transfer date and time.
What cost does the recipient use later?
The recipient normally starts with Bitcoin's GBP market value on the gift date. This amount becomes their cost when they later sell, swap, spend, or gift it.
A qualifying spouse or civil partner transfer works differently. The recipient usually takes over the donor's allowable cost for the transferred Bitcoin.
This matching value helps both people support future tax calculations.
Three worked family examples
Assume a donor gives 0.10 BTC when its GBP market value is £6,000. Assume the donor's allowable pooled cost for that 0.10 BTC is £2,000.
A gift to an adult child is normally a £6,000 crypto asset disposal. The donor has a £4,000 gain before UK CGT reliefs or losses. The child's acquisition cost is normally £6,000.
The same figures usually apply to a gift to a sibling. Being close family does not create a Bitcoin gift tax exemption for CGT.
By contrast, a transfer to a cohabiting spouse or civil partner normally uses no-gain/no-loss treatment. No gain is created at that point. The recipient takes the donor's £2,000 allowable cost for that Bitcoin.
For a non-spouse transfer, record the BTC/GBP valuation used for the deemed disposal. Also record the quantity received. The valuation is the recipient's starting cost.
Later Bitcoin purchases may join the recipient's Bitcoin pool under share-pooling rules. A later sale needs records for the whole pool, not only the gift.
Keep records for both parties from the transfer date, including the market-value calculation, exchange source, exact timestamp, gift letter, and wallet transaction trail. These records support future calculations for both people.
Choose the cleanest route for a family gift
Giving existing Bitcoin, buying Bitcoin to gift, and giving cash are not the same. Similar balances can create different CGT records, ownership evidence, and price risk.
The cleanest route depends on what you want to give. It also depends on whether you already hold the Bitcoin.
The problem is that a simple wallet transfer can create a tax event.
Compare the three practical routes
| Route | Sender's CGT record | Recipient's evidence | Price-risk window |
|---|
| Gift existing BTC | Market-value disposal, usually | Gift letter and wallet trail | Until transfer confirms |
| Buy BTC specifically to gift | Disposal still exists, often small gain or loss | Purchase record plus gift trail | From purchase to transfer |
| Give cash for own BTC purchase | No Bitcoin disposal by sender | Recipient's own exchange purchase | Recipient chooses purchase time |

Useful for this topic
A dedicated crypto tax record book can keep a family gift letter, valuation note, and wallet evidence together. This helps when a sale happens years after the transfer.
- One place for the BTC amount, GBP value, and exact transfer time.
- Space for transaction IDs and both wallet addresses.
- A paper trail for the recipient's future Capital Gains Tax calculation.

Send bitcoin without avoidable loss
Confirm the receiving address through a second channel. Send a small test amount for a large gift. Wait for confirmations before sending the rest.
Bitcoin transfers cannot normally be reversed. Never share a seed phrase or private key to check a wallet.
The most common error is sending to an unchecked address. A test payment can prevent an irreversible loss.
Keep records and check the seven-year rule
Keep a file linking the blockchain transaction to the valuation, pooled cost, and gift intention. Save the date, time, BTC amount, BTC/GBP source, TXID, both addresses, and signed gift letter.
Good records explain what happened years after the wallet transfer.
Annual exemption and IHT evidence
An outright gift to an individual is usually a potentially exempt transfer for IHT. Surviving seven years normally removes it from the estate.
The £3,000 annual exemption can reduce a gift's value. Keep the original valuation because Bitcoin may rise before death.
IHT and CGT use different rules. A transfer can create a CGT disposal now and still matter for IHT later.
When must HMRC be told?
Report the donor's disposal through Self Assessment when taxable gains or proceeds exceed HMRC thresholds. The normal online deadline is 31 January after the tax year.
Keep records for at least five years after the 31 January filing deadline. Keeping them until the recipient disposes of the Bitcoin is safer.
This matters because the recipient may sell many years later.
Do not rely on this standard framework without specialist advice in certain cases. Get advice if either person is not UK tax-resident. Do the same if the couple are separating or no longer living together. Seek advice if the transfer relates to work or a business. This also applies if the recipient is a trust or company. Get advice if the donor has died or large-estate IHT planning is involved. Overseas gifts may create tax duties where the recipient lives.
A cross-border family gift needs checks for both people's tax residence. Nationality and wallet location alone do not decide this.
HMRC guidance may apply to a UK-resident donor's crypto asset disposal. The recipient's country may charge tax or require reports on receipt or sale.
A UK resident receiving Bitcoin from abroad should keep the sender's gift letter. They should also keep the BTC/GBP valuation and transaction evidence.
Non-UK residence does not always remove UK tax issues. Temporary non-residence, domicile, and estate-planning rules can still matter.
What people ask
Can you gift bitcoin tax-free in the UK?
You can usually transfer Bitcoin to a cohabiting spouse or civil partner without immediate CGT. Gifts to children, parents, and siblings normally use market value. These gifts can create a taxable gain for the sender.
Is receiving bitcoin as a gift taxable in the UK?
Receiving a genuine Bitcoin gift is usually not Income Tax. On a later sale, swap, spend, or gift, cost usually equals GBP market value on the gift date. Qualifying spouse transfers are an exception.
Can I give my child cash to buy bitcoin instead?
Giving cash avoids a Bitcoin disposal by the donor. The cash gift can still matter for IHT. The child should buy through their own account and keep bank, exchange, and wallet records.
How long should I keep bitcoin gift records?
Keep records for at least five years after the 31 January filing deadline. Keep them until the recipient disposes of the Bitcoin if possible. Their cost basis may be needed much later.
The essentials:- A Bitcoin gift to a child or sibling normally creates a market-value CGT disposal for the donor.
- A qualifying spouse or civil-partner transfer usually defers the gain through no-gain/no-loss treatment.
- Cash for the recipient's own purchase can create cleaner Bitcoin acquisition records, but does not remove IHT questions.
- Save the valuation, TXID, wallet addresses, pooled cost, and signed gift letter before the transfer.
Make the transfer only after recording its value
Before sending, identify the relationship rule and choose the route. Capture the GBP valuation and prepare the gift letter. Check the address before sending any Bitcoin.
Contemporaneous evidence protects the donor's CGT position. It also protects the recipient's cost basis.
Record the details before the blockchain transaction confirms.
