Can I Sell My House to My Son or Daughter for £1?

The Short Answer

Every week, we hear from parents who think they’ve found a clever loophole.

“Can I just sell my house to my daughter for £1?”

The answer catches most people off guard: yes, you can do it, but it’s almost always a terrible idea.

Here’s what most families don’t realise: HMRC doesn’t care what’s written on the sale contract. When you sell a property to family for £1, they’ll treat it exactly as it is, a gift at full market value. That triggers Capital Gains Tax on you, potential Stamp Duty on your child, and Inheritance Tax complications if you die within seven years.

Add in mortgage lender refusals, care home fee investigations, and Gift with Reservation rules (which we’ll explain shortly), and what seemed like a simple family arrangement becomes a costly legal mess.

The fallout from these transactions is more common than you might think.

Let’s walk through exactly why this “£1 sale” strategy backfires, and what actually works instead.

(If you already know the tax issues and just want solutions, skip straight to “What Actually Works“.)

The “Connected Persons” Rule: Why HMRC Ignores Your £1 Sale Price

First things first: let’s talk about how HMRC actually sees your transaction.

When you sell a property to a family member for £1 (or any amount significantly below market value), HMRC has specific rules to prevent tax avoidance. They’re called the “connected persons” rules, and they’ve been in place for decades.

Under Section 18 of the Taxation of Chargeable Gains Act 1992, any disposal to a “connected person”, which includes your children, parents, siblings, and grandchildren, is automatically treated as if it happened at full open market value.

It doesn’t matter what you actually received.

You could sell a £300,000 property to your daughter for £1, and HMRC will calculate your Capital Gains Tax (CGT) liability as if you received £300,000. If the property isn’t your main residence and you’re liable for CGT, you’ll face CGT at 18% on the portion of the gain that falls within your unused basic-rate income tax band, and 24% on any amount above that (HMRC Capital Gains Manual).

There is no relief for the fact that no cash changed hands.

Families are caught out by this rule time and again, especially when they haven’t taken professional advice beforehand.

That brings us to the first major tax hit.

Capital Gains Tax: The First Problem

If the property you’re “selling” for £1 is your main home, you’re usually fine. Principal Private Residence Relief (PPR) means most people don’t pay CGT when selling their primary residence.

But what if it’s not your main home?

But if it’s a second property, a rental, or a home you haven’t lived in recently, CGT applies.

And as I mentioned, HMRC calculates the gain based on the property’s market value, not the £1 you received.

Here’s a worked example that shows just how painful this can be.

Example:

You don’t have to be a tax expert to see the problem here.

You can offset your annual CGT exemption (currently £3,000 for the 2025/26 tax year), but that barely makes a dent in a six-figure gain.

There are some technical reliefs available in specific situations, like Gift Holdover Relief under Section 165 TCGA 1992, but these generally don’t apply to residential investment properties. They’re designed for business assets, not buy-to-let flats.

Unfortunately, the tax pain doesn’t stop with you.

Stamp Duty Land Tax: The Second Problem

Now let’s talk about your son or daughter, the person receiving the property.

Even though they’re only paying £1, they may still face a Stamp Duty Land Tax (SDLT) bill.

Here’s why.

If there’s an outstanding mortgage on the property, and your child takes over responsibility for that debt (or you use the £1 plus their assumption of the mortgage to clear it), HMRC calculates SDLT on the outstanding mortgage amount, not the £1 purchase price.

Let me show you how this plays out in practice.

Example:

Under the current SDLT thresholds (as of March 2026), residential property SDLT is charged at:

• 0% on the first £125,000
• 2% on the portion from £125,001 to £250,000
• 5% on the portion from £250,001 to £925,000
• And so on for higher amounts

So on a £180,000 mortgage assumption, your child would pay:

But wait, there’s more.

If the property isn’t going to be your child’s main home (e.g., they already own a property), they’ll also pay the 5% additional dwelling surcharge on the entire amount. That adds another £9,000 to the bill in this example.

One thing that comes up consistently is that families underestimate, or completely overlook, the SDLT implications of “below market value” sales when mortgages are involved.

Note: The SDLT rates and thresholds above apply to properties in England only. Property transactions in Wales are subject to Land Transaction Tax (LTT), which has different rate bands and thresholds, the standard 0% band extends to £225,000 (not £125,000). If you are transferring a Welsh property, consult the Welsh Revenue Authority for current LTT rates.

And there’s one more tax to consider, arguably the most misunderstood one.

Inheritance Tax: The Third Problem

Even if you’re willing to pay the CGT and your child can cover the SDLT, there’s a third tax waiting in the wings: Inheritance Tax (IHT).

This is where the “seven-year rule” comes in, and where many families’ plans completely unravel.

Here’s how it works.

When you gift a property (or sell it for a nominal amount like £1, which HMRC treats as a gift), it’s classified as a Potentially Exempt Transfer (PET).

What does that mean in plain English?

If you live for seven years after making the gift, it falls outside your estate for IHT purposes.

But if you die within seven years, the property’s value gets added back into your taxable estate.

If your estate exceeds the IHT nil-rate band, currently £325,000, frozen until April 2031, your beneficiaries will face a 40% tax charge on the amount over the threshold.

(There’s also a residence nil-rate band of up to £175,000 if you’re passing your main home to direct descendants, but the rules are complicated and phase out for estates over £2 million.)

Now, you might be wondering: “What about taper relief? Doesn’t that reduce the tax over time?”

What About Taper Relief? Does That Help?

Many people have heard of “taper relief” and think it reduces the value of the gift over time.

It doesn’t.

Here’s the common misconception.

Taper relief only reduces the tax rate (not the value of the gift) if the gift exceeds the nil-rate band and you die between three and seven years after making it. For deaths in years 3–4, the rate drops to 32%; years 4–5, it’s 24%; and so on.

But if the gift plus your other assets don’t exceed the nil-rate band, taper relief doesn’t help at all. The value of the gift is still fully counted.

In many cases, it’s actually more tax-efficient for your children to inherit the property through your will. They’ll benefit from the nil-rate bands and potentially the residence nil-rate band, and won’t face a CGT bill because inherited property gets “rebased” to market value at the date of death.

Now, if you’re reading this because you’re worried about care home fees, this next section is critical.

Why the “Care Home Fee” Strategy Backfires Spectacularly

One of the most common reasons we hear for families wanting to transfer property for £1 is fear of care home fees.

The logic goes like this: “If I give my house to my children now, the local authority can’t count it when assessing whether I can afford care, right?”

Wrong.

Dead wrong.

Local authorities are very alert to this, and they have the power to investigate “deprivation of assets”, deliberate attempts to reduce your wealth to qualify for state-funded care.

In England, councils can apply the deprivation-of-assets rules under the Care Act 2014 and related charging regulations. In Wales, local authorities apply equivalent rules under the Social Services and Well-being (Wales) Act 2014. In either country, if a council believes you transferred your home specifically to avoid care costs, they can treat you as if you still own it when calculating your contributions, and in some cases, they can pursue the person you gave it to for recovery of care costs.

And it’s not just about timing.

Even if you transferred the property years before needing care, if the council can demonstrate that avoiding care fees was a significant motivation, they can still challenge it.

Councils have become increasingly sophisticated in tracing asset transfers, and the penalties can be severe.

But what if you’ve already transferred the property and you’re still living there? Let me explain why that creates yet another problem.

The “Gift with Reservation” Trap: Living in a House You’ve Gifted

Here’s another common scenario.

You “sell” or gift your house to your children for £1, but you carry on living in it as you always have. After all, it’s still your home, right?

Sounds reasonable. HMRC disagrees.

Unfortunately, this triggers something called the Gift with Reservation of Benefit (GROB) rules under the Finance Act 1986.

(Don’t worry. I’ll explain what that means in a second.)

The principle is simple: if you continue to benefit from an asset you’ve gifted (such as living in a house rent-free), HMRC treats the gift as incomplete for IHT purposes. The property stays in your estate, regardless of how long ago you made the gift or whether seven years have passed.

This is one of the most commonly misunderstood areas of estate planning. Families think they’ve protected the property from IHT by transferring it to their children, but because Mum or Dad is still living there, the planning fails completely.

The most common ways to fall outside the GROB rules are:

1. Pay a full market rent to the new owner (your child), reviewed regularly and actually paid, or
2. Genuinely share occupation with the new owner (they live there too)

And I do mean full market rent, reviewed annually and actually paid. HMRC will challenge anything that looks like a sweetheart deal.

There’s also a very narrow visiting exception: HMRC’s guidance (IHTM14333) treats visiting as acceptable only if it’s genuinely minimal, less than one month a year staying with the new owner, and no more than two weeks a year staying alone in the property. Exceed those limits, and they’ll consider it a reservation of benefit.

Anything beyond that, and the gift is ineffective for IHT.

So far we’ve covered the tax consequences, but there’s still a major practical barrier that stops most £1 sales in their tracks.

The Lender Will Probably Say No

Even if you’re prepared to deal with all the tax issues, there’s a practical problem most people don’t anticipate: mortgage lenders.

If you have an outstanding mortgage on the property, your lender’s consent is required before you can transfer it, even to a family member. Most mortgage agreements include a clause requiring lender approval for any transfer of ownership.

And here’s the reality: lenders almost never approve £1 sales.

Lenders are highly unlikely to agree to a £1 sale. They’ll see it for what it is: a gift. And they’ll want to ensure the new owner can afford the mortgage and meets their lending criteria.

Which means your child will need to go through a full mortgage application.

Your child will likely need to apply for a new mortgage in their own name to buy you out at market value or remortgage the property. That means affordability checks, credit checks, valuation, legal costs, the full process.

And if your child already has a mortgage on their own home, taking on a second property might not be financially viable, especially with affordability rules having tightened significantly in recent years.

Family transfer plans frequently stall because of lender refusal, and by the time sellers look for alternatives, they’re often under time pressure to complete.

Right, so we’ve established that a £1 sale creates more problems than it solves. What actually works?

What Actually Works: Better Alternatives to a £1 Sale

If your goal is to pass property to your children efficiently (without triggering unnecessary tax bills), here are the strategies that genuinely work.

Each comes with its own considerations, so you’ll want to get professional advice, but at least these approaches don’t automatically trigger multiple tax charges.

Here are some approaches that may be more effective, depending on your circumstances:

1. Allow Inheritance Through Your Will

This is often the simplest and most tax-efficient route.

Your children inherit the property on your death with no CGT liability (because of the CGT “uplift” on death), and your estate benefits from the IHT nil-rate band (£325,000) plus potentially the residence nil-rate band (up to £175,000), provided the property passes to direct descendants. That allowance starts to taper once the net estate exceeds £2 million, reducing by £1 for every £2 over the threshold, and is fully exhausted at £2.35 million.

Yes, it means waiting. But it also means avoiding three separate tax charges.

2. Lifetime Gifting with Proper Planning

If you genuinely want to transfer property during your lifetime, do it properly:

• Get professional tax advice first
• Understand the seven-year rule and your potential IHT exposure
• If you want to remain in the property, pay a proper market rent
• Consider whether Gift Holdover Relief might apply (rare for residential property)
• Keep clear records of the transaction and the market value

3. Use a Trust

In some cases, transferring property into a trust can provide more flexibility and control, though trusts bring their own tax complications and costs.

This is specialist territory and absolutely requires professional legal and tax advice.

4. Sell at Market Value and Gift the Proceeds

If your goal is to pass wealth to your children, consider selling the property at full market value (either on the open market or to a cash buyer like us) and gifting the proceeds.

Why does this work better?

Cash gifts are much simpler to manage, easier to split between multiple children, and avoid the lender and SDLT complications that come with transferring the property itself. They’re still subject to the seven-year rule for IHT, and if the property isn’t your main residence you’ll face CGT on the sale, but at least your children avoid the SDLT liability and ongoing tax obligations that come with receiving the property directly.

5. Sell and Downsize

If care fees are the concern, selling and downsizing might make more sense than trying to hide assets.

The proceeds can fund care, and if you plan carefully, you can still leave a meaningful inheritance.

The Bottom Line

Can you sell your house to your son or daughter for £1?

Yes.

Should you?

Almost never.

The tax consequences alone. CGT for you, SDLT for them, and IHT exposure if you die within seven years, usually wipe out any perceived benefit. Add in the GROB rules if you keep living there, the care home fee risks if that’s your motivation, and the lender complications if there’s a mortgage, and it quickly becomes a costly mistake.

The aftermath of these transactions is all too common. By the time families realise the problems, they’re often facing hefty tax bills, legal disputes, or having to unwind the arrangement entirely.

Here’s what we recommend instead:

If you’re thinking of transferring property to your children, speak to a qualified solicitor and tax adviser before you do anything. They’ll help you understand the real costs and identify a structure that actually achieves your goals without creating new problems.

And if you need to sell quickly, whether to release funds, settle an estate, or avoid a problematic transfer, we can help with that too.
