Can I Sell My House to My Son for £1? Tax & Legal Implications 2026
Technically yes.
Selling your house to your son – or daughter for that matter – for £1 is a real thing that solicitors do, with full conveyancing and proper paperwork. The transaction sits in a slightly strange place between a sale and a gift, and HMRC treats it as the latter regardless of what the contract says. That’s the part that catches people out. The £1 doesn’t make it a sale in the tax authorities’ eyes; the absence of market value makes it a gift, with all the inheritance tax, capital gains tax, and care-fee implications that come with one.
Is It Actually Legal to Sell Your House for £1?
Yes. There’s no law in England and Wales preventing a property owner from selling to whoever they choose at whatever price they choose. The Land Registry will register the transfer, a conveyancing solicitor will draft the contracts, and the keys change hands.
What HMRC does with the transaction is a separate matter.
A sale at significantly below market value is treated as a gift for tax purposes. The £1 consideration doesn’t change this. HMRC looks at the “chargeable consideration” (the actual market value of what’s being transferred) when calculating most taxes, not the nominal price on the contract.
What Does It Cost in Stamp Duty?
This is the one tax where selling for £1 actually does help, provided the property has no mortgage attached.
If the property is mortgage-free and being gifted outright, no Stamp Duty Land Tax (SDLT) is payable. There’s no chargeable consideration above the threshold, so the SDLT calculation comes out at zero.
If there’s still a mortgage on the property and your child takes it on as part of the transfer, SDLT becomes payable on the value of the outstanding mortgage. If the mortgage exceeds the £125,000 nil-rate threshold (or £300,000 if he’s a first-time buyer), normal SDLT rates apply to the mortgage value.
If your son already owns another property and the gifted home will be a second home or rental, the 5% SDLT surcharge applies on top.
What About Inheritance Tax?
This is the tax that catches most people. The seven-year rule is the central piece.
When you gift property (which is what a £1 sale effectively is), it’s classified as a “Potentially Exempt Transfer” (PET) by HMRC. If you survive seven years from the date of the gift, the property’s value falls outside your estate and no inheritance tax is payable on it.
If you die within seven years, the property’s value is added back to your estate for IHT purposes. The applicable rate depends on how long you survived after the gift:
- Within 3 years: full 40% IHT applies
- 3 to 4 years: 32%
- 4 to 5 years: 24%
- 5 to 6 years: 16%
- 6 to 7 years: 8%
- 7+ years: 0%
This is “taper relief” and it only applies if the gift’s value exceeds the £325,000 nil-rate band.
There’s a significant catch. If you continue to live in the property after gifting it to your son without paying him market rent, HMRC treats the gift as a “gift with reservation of benefit”. The property stays in your estate for IHT purposes regardless of how long you survive. The seven-year rule offers no protection.
To avoid this trap, you either need to move out, or pay your son a documented market-rate rent.
What About Capital Gains Tax?
If the property has been your main residence throughout your ownership, Private Residence Relief applies and there’s no CGT to pay on the gift. This is the case for most homeowners gifting their primary residence.
If it’s a second home, rental property, or somewhere you haven’t lived in for part of your ownership, CGT becomes payable. HMRC calculates the gain based on the property’s market value at the date of the gift, not the £1 contract price. You’re taxed on the increase from your original purchase price to the current market value, at 18% or 24% depending on your tax bracket (residential property rates apply).
CGT on a gifted property is payable by the donor (you), not the recipient (your son). This is the part that catches people out who assume gifting equals tax-free.
Will Selling for £1 Affect Care Fees?
Local authorities assess your assets when calculating what you owe for residential care. If you gift your home to your son and later need care, the council can investigate whether the gift was made deliberately to avoid care fees. This is called “deliberate deprivation of assets”.
There’s no time limit on this assessment. The seven-year rule that applies to IHT doesn’t apply here. A gift made twenty years ago can still be reversed if the council determines it was made with care fees in mind.
The factors the council considers include the timing of the gift, your health at the time, whether care was a realistic prospect, and whether there were other legitimate reasons for the transfer.
This isn’t a reason to never gift your home. It’s a reason to do it for genuine estate planning purposes, document those reasons, and ideally do it well before any health concerns arise.
What Are the Practical Steps?
You’ll need a conveyancing solicitor to handle the transfer. Most will recommend a Deed of Gift rather than a £1 sale; the legal effect is the same but the paperwork is cleaner. Expect to pay £500 to £1,500 for the solicitor’s fees.
You’ll also need a professional valuation of the property for HMRC purposes. The valuation establishes the gift’s value for IHT and CGT calculations. Expect to pay £400 to £600 for a RICS valuation.
If there’s a mortgage on the property, your lender’s consent is required before the transfer can complete. Many lenders won’t agree to a transfer that doesn’t pay off the existing mortgage. You may need to redeem the mortgage first, which can trigger early repayment charges.
The Land Registry needs to be notified of the transfer. The registration fee depends on the property’s value and ranges from £40 to £455.
Finally, you should get tax advice before proceeding. The interactions between IHT, CGT, and care-fee assessment are not straightforward, and a tax specialist can structure the transfer to minimise exposure.
When Selling Directly Might Be a Better Option
For some homeowners, the question of “should I gift this property” is bundled together with “I want to release the equity in this property”. The two aren’t the same, and a gift doesn’t actually put any money in your pocket.
If the underlying goal is to release capital, downsize, or simply sell up, a direct cash sale from a company that buys any house is often the cleaner route. At Sell House Fast, we buy properties across England and Wales without the complications that a family gift introduces. The seller gets cash; the property changes hands; there’s no seven-year rule, no care-fee question, no CGT surprise. Whether you’re trying to sell a property fast in London or Leeds, we can help.
Sell with Speed and Certainty Instead
If gifting the property no longer feels like the right route, or if you’ve decided you need the capital rather than the family legacy, we can help. We make cash offers within 24 hours, cover all legal fees, and complete in as little as seven days. No estate agent, no chain, no surprise tax bills further down the line.
FAQs
Can I really sell my house to my son for £1?
Yes, the transaction is legal in England and Wales. HMRC treats it as a gift for tax purposes regardless of the £1 contract price, with all the inheritance tax and capital gains implications that follow.
Will I have to pay Stamp Duty if I sell for £1?
Not if the property is mortgage-free. If your son takes on an existing mortgage above the SDLT threshold, stamp duty becomes payable on the mortgage value.
What’s the seven-year rule for gifting property?
Property gifts become fully exempt from inheritance tax if you survive seven years after the transfer. If you die within seven years, IHT applies on a sliding “taper relief” scale.
Can the council take the property back to pay for my care?
The local authority can investigate whether the gift was made to deliberately avoid care fees and reverse it if so. There’s no time limit on this assessment.
Do I need a solicitor to gift my house to my son?
Yes. A conveyancing solicitor must draft the transfer documents and lodge them with the Land Registry. Most will recommend a Deed of Gift rather than a £1 sale.
Will I pay Capital Gains Tax on gifting my home?
Not if it’s been your main residence throughout your ownership. Second homes and rental properties attract CGT on the gain between purchase price and current market value.
Can my son live in the house if I keep living there too?
Yes, but if you live there without paying him market rent, HMRC treats it as a “gift with reservation of benefit” and the property stays in your estate for inheritance tax purposes.
