Gifting property or assets to family feels generous. Many people see it as a simple transfer. HMRC (His Majesty’s Revenue and Customs) does not.
In the UK, gifting often triggers Capital Gains Tax (CGT), even when no money changes hands. This catches homeowners, investors, and business owners off guard every year. The rules are strict. The mistakes are expensive. And most people only realise too late.
This guide explains exactly how CGT works when gifting assets in the UK, who it affects most, and where people go wrong.
Why Gifting Can Trigger Capital Gains Tax?
HMRC treats a gift as a disposal. That matters.
A disposal happens whenever you:
- sell an asset
- transfer ownership
- give it away
The tax system assumes you disposed of the asset at market value, not at zero. Even if you gift a property to your child for nothing, HMRC calculates CGT as if you sold it at full market price.
This rule applies to:
- property
- shares
- land
- business assets
- investment portfolios
There are no exceptions based on family relationships.
Gifting a Property to a Child: The Most Common Scenario
This is where most people get caught.
If the property is not your main residence, CGT usually applies.
That includes:
- buy-to-let properties
- holiday homes
- properties previously rented out
- inherited properties that were never your main home
HMRC calculates the gain like this:
- Market value at date of gift
- Minus original purchase price
- Minus allowable costs
If the property rose in value, CGT is due.
| Example:
You bought a second home for £200,000. It’s worth £400,000 today. You gift it to your child. The taxable gain is £200,000. After the annual CGT allowance (£3,000, which remains the allowance for 2026/27), the rest is taxable. |
CGT rates for residential property:
- 18% for basic-rate taxpayers
- 24% for higher and additional-rate taxpayers
What If the Property Was Your Main Home?
Private Residence Relief can eliminate CGT — but only if:
- The property was your main residence for the entire ownership period
- It was never rented out (with limited exceptions)
If the property was once your home but later rented, partial CGT often applies.
This is a common trap. Many people assume “it used to be my home” means no tax. It does not.
Gifting Shares, Investments, or Portfolios
CGT applies to gifted shares and investments in the same way.
HMRC uses:
- market value on the date of the gift
- minus original acquisition cost
This applies to:
- listed shares
- unit trusts
- investment funds
- cryptoassets
The current CGT rates for non-property assets are:
- 18% for basic-rate taxpayers
- 24% for higher and additional-rate taxpayers
High-net-worth individuals often overlook CGT when gifting portfolios because no cash is involved. HMRC does not overlook it.
Gifting Business Assets: Holdover Relief
This is where planning matters most.
Certain business assets may qualify for Holdover Relief. This allows the CGT to be deferred, not erased.
If relief applies:
- No CGT is paid at the time of the gift
- The recipient inherits the original base cost
- CGT is paid when they later dispose of the asset
Holdover Relief may apply to:
- trading businesses
- business assets
- unlisted shares
It does not apply automatically. Claims must be made correctly.
Capital Gains Tax vs Inheritance Tax: The Overlap People Miss
Gifting can trigger CGT now and Inheritance Tax (IHT) later.
This surprises many families.
- CGT is assessed at the time of the gift
- IHT depends on whether the donor survives seven years
If the donor dies within seven years, IHT may still apply. CGT paid is not refunded.
This is why gifting solely to “avoid tax” often backfires.
Annual CGT Allowance: Smaller Than Most People Think
The annual CGT exemption is now £3,000 per person and £1,500 for trusts.
This was:
- £12,300 in 2022
- £6,000 in 2023
The reduction means far more gifts now trigger CGT.
Married couples and civil partners can use two allowances, but transfers between them must be structured correctly.
Common and Costly Mistakes
These mistakes appear repeatedly in HMRC enquiries:
- Assuming gifts are tax-free
- Ignoring the market value rule
- Forgetting CGT deadlines for property (60 days)
- Mixing CGT and IHT planning without advice
- Gifting assets shortly before death
- Underestimating valuation requirements
Once a gift is made, the tax position is fixed.
When Professional Advice Becomes Essential?
CGT planning works best before the gift, not after.
Professional advice helps:
- calculate true exposure
- identify reliefs
- time disposals correctly
- avoid penalties and interest
For high-value property or business assets, advice often saves more than it costs.
Questions People Ask – Frequently Asked Questions (FAQs)
- Do I pay capital gains tax when gifting property to family?
Yes. HMRC treats most gifts as a sale at market value, even if no money changes hands.
- Is there capital gains tax when gifting a house to my children?
Usually yes, unless the property qualifies for full Private Residence Relief.
- Can I avoid capital gains tax by gifting assets instead of selling?
No. Gifting does not bypass CGT. The tax is still calculated using market value.
- Are there any CGT reliefs when gifting business assets?
Yes. Business Asset Hold-Over Relief may defer CGT if strict conditions are met.
- Do I need to report a gifted property to HMRC?
Yes. If capital gains tax applies, you must report the gift and pay any CGT within the required UK reporting deadlines.
Final Thoughts
Gifting property or assets in the UK is never just a family decision. It is a tax decision. HMRC treats gifts as disposals. Market value applies. CGT often follows.
Understanding the rules before you transfer ownership protects both you and your family from avoidable tax bills.
