The Risks of Gifting Property and Still Living in It
Many homeowners consider gifting their property to their children as a way to finalise their estate planning and reduce a future Inheritance Tax bill. However, staying in the property after the transfer is a complex legal and tax area that often triggers unintended consequences.
Under UK law, if you give away your home under its current market value but continue to reside there without paying a full market rent, HMRC may view this as a Gift with a Reservation of Benefit. What is commonly misunderstood is that the law on gifts isn't just about parents giving to their child; it applies to every undervalued transaction and to any intent to give something away for free.
When you gift a property, and still live in it, and don't pay full market rent, you are liable to pay a Pre-Owned Assets Tax (POAT) every year to HMRC; declared in your annual income self-assessment. This article explores how to navigate these rules, the impact of POAT, and the significant risks to you, even if your assets are below the IHT thresholds.
What is a gift with a reservation of benefit?
A Gift with Reservation of Benefit (GWR) is a tax rule used by HM Revenue & Customs (HMRC) to stop people from giving away their assets on paper while still using them in reality. A GWR is essentially a pretend gift because you're giving away your property ownership, but you reserve the benefit of still living there.
For example: A mum and dad sell their home to their child for no money; a gift. They do it to reduce their Inheritance Tax and to remove the asset from Care Home Fee calculations. The mum and dad aren't moving out, and will still use the house as their home rent-free.
If you do this, then HMRC will still treat the asset as if you still owned it for Inheritance Tax (IHT) purposes, or you'll need to pay a Pre-Owned Assets Tax (POAT).

What does the law say about POAT?
The Pre-Owned Assets Tax (POAT) is triggered if you are connected to the buyer of a home you are going to live in, and you sold it to them for under market value, or even gave it away for free.
Paragraph 4 (4): The disposal by the chargeable person of an interest in land is a “non-exempt sale” if (although not an excluded transaction) it was a sale of his whole interest in the property for a consideration paid in money in sterling or any other currency; and, in relation to a non-exempt sale
In plain English, this means a non-exempt sale is a sale (disposal) that is not an excluded transaction (such as a normal arm's-length sale at full price). So, if you sell your property for less than its market value (MV) and continue to live there, the Act triggers a calculation to ensure you pay tax on the "gifted" portion of that value.

Expert Tip - How do you gift property to your children?
You can gift property either by a transfer of equity (using a deed of gift) or by sale and purchase, often with some consideration (money) changing hands. We cover the complete processes here: How to gift your property to your children.

Define a Connected Person
The definition of "connected persons" is found in Section 993 of the Income Tax Act 2007, which the Finance Act 2004 relies upon.
- 1
Transactions between Connected Persons (Parents/Children)
If you gift property to a connected person (which includes parents, children, siblings, and spouses), HMRC ignores the actual price paid if it is lower than the market value.
- Deemed Market Value: Under Paragraph 10(1)(a) of Schedule 15, for a sale to be "excluded" from POAT, it must be at full consideration. Between connected persons, HMRC will almost always assume the transaction was not at arm's length.
- The Intent: HMRC assumes that a sale from a parent to a child at a discount is a partial gift. Therefore, the Appropriate Proportion calculation we discussed earlier is automatically triggered because the sale wasn't a purely commercial transaction.
- 2
Transactions between unconnected persons (Friends)
If you sell your property to a friend or a stranger, the rules are slightly more flexible, provided you can prove it was a genuine commercial deal.
- Arm's Length: If you can prove the sale was at arm's length, meaning you negotiated the best price possible as if you were strangers, the transaction may be an excluded transaction under Paragraph 10.
- Evidence: However, who gives away something for nothing? That's why if you sell to a friend at a significant discount, HMRC will still treat the "discounted" element as a gift. They will look for a "bounty" (an intention to benefit the friend). If there is a "bounty," the POAT rules apply just as they would with a family member.
Who is a Connected Person?
The legislation defines a connected person as more than just your mum and dad, and includes:
- Your spouse or civil partner.
- Your relatives (siblings, ancestors, or lineal descendants).
- The spouses or civil partners of your relatives.
- Business partners.
How do you calculate the POAT?
The Pre-Owned Assets Tax (POAT) for property is calculated based on its annual market rental value. To determine the chargeable amount, you must first establish the full rent the property would realistically command if it were let on the open market at the start of the tax year. If you gifted only a portion of the property or provided only part of the purchase funds (the Appropriate Proportion), apply that percentage to the total rental value.
From this figure, you subtract any actual rent or service charges you are legally obliged to pay to the owner; if the remaining balance exceeds the £5,000 de minimis threshold, the entire amount is added to your annual income and taxed at your marginal rate (20%, 40%, or 45%).
Expert Tip - HMRC aren't stupid
Every registration at the Land Registry states the consideration paid between the buyer and seller. If it is disposed of for less than they think is reasonable, and you don't declare it, prepare yourself for this to be flagged in the future.
HMRC is more likely to challenge the valuation. If you say the house was worth £300,000 but the District Valuer says £350,000, the "gifted" portion increases, and so does your annual tax bill. You may argue that, in transactions between unconnected people, there was no intention to gift; perhaps they just wanted a quick sale. Between a mother and son, that argument is virtually impossible to win; the law assumes an intention to provide a gift.
Summary of Risks
Feature | Connected Person | Unconnected Person |
Market Value Test | Strictly enforced by HMRC. | Easier to argue "arm's length" price. |
POAT Trigger | High risk if any discount is given. | Only triggered if a clear gift intent exists. |
Evidential Burden | Very high; requires formal valuations. HMRC may instruct their own RICS valuer. | Moderate; requires proof of market marketing. |

How do you avoid the Pre-Owned Assets Tax?
You can avoid the POAT through HMRC's legitimate processes:
- 1
Pay a Market Rent
You can ignore the POAT if you pay a fair market rent to live in the property.
- 1
The £5,000 Rule
If the total annual rental value of the benefit is less than £5,000, you generally do not have to pay POAT.
- 3
Opt Out of POAT
The Finance Act 2004 allows you to opt out of paying the POAT. Under Paragraph 21, a taxpayer may make a formal election to ignore POAT and have the property treated as part of their estate for Inheritance Tax purposes. This is often used by those who would rather their heirs pay IHT later than pay an annual Income Tax bill now.
This option would allow your parents to gift their home and still live in it, but pay their Inheritance Tax when they die.
Expert Tip - If you choose a fair market rate, don't ignore legal landlord obligations
If the children are receiving rent, then they are landlords, and they must adhere to their legal obligations as landlords. This ranges from having EICR checks every 5 years to an annual boiler check.

CEO of SAM Conveyancing
Does POAT matter if your assets are below the IHT threshold?
Yes, it matters. In fact, POAT is often more frustrating for those with assets under the IHT threshold because it forces you to pay tax now on an estate that wouldn't have owed any tax later. If your estate is worth less than the current IHT thresholds, POAT is essentially a voluntary tax you pay during your lifetime that could have been avoided.
Inheritance Tax Rates & Thresholds
- if you leave everything above the £325,000 threshold to your spouse, civil partner, a charity or a community amateur sports club; OR.
- If you give away your home to your children (including adopted, foster or stepchildren) or grandchildren, your threshold can increase to £500,000.
Expert Tip - Opt to pay from your IHT if below the threshold
If you are caught by POAT because you've gifted your property undervalued and you still live in it, then check if your estate is under the IHT threshold. If it is, or is likely going to be, then contact HMRC and elect not to pay POAT, and have the asset included in your IHT (Paragraph 21, Schedule 15).
An election must typically be made by the 31st January following the end of the first tax year in which the POAT charge would apply. If you miss this window, you may be stuck paying the annual Income Tax charge even if you don't owe a penny in IHT.

How do you notify HMRC to opt out?
To notify HMRC that you wish to opt out of the Pre-Owned Assets Tax (POAT) and instead have the property treated as part of your estate for Inheritance Tax purposes, you must submit an HMRC Form IHT500.
The Step-by-Step Notification Process
- Download Form IHT500: Use the official HMRC Form IHT500.
- Complete the Details: You will need to provide:
- Your personal details (National Insurance number, address, etc.).
- The date the property was originally disposed of (the gift or sale date).
- The address and description of the property.
- The capacity in which you are signing (usually as the chargeable person).
- Submit to the Correct Office: All POAT elections must be sent by post to the HMRC Inheritance Tax office at: Inheritance Tax, HM Revenue and Customs, BX9 1HT
- One Form Per Asset: If you are opting out of POAT for multiple properties or different types of assets (e.g., a house and a collection of expensive art), you must complete a separate IHT500 for each one.
What other risks are there?
It can be easy to become hyper-focused on the tax risks; however, have you considered what'll happen if you lose your home? Here's how that can happen.
- 1
Bankruptcy
If the owner of the house becomes bankrupt, the property could be seized and sold to pay off the debts, making you homeless. If you jointly share the ownership IE not a complete gift, the bankruptcy process is different.
- 2
Occupier Waiver
If the owner of the house obtains a mortgage and the gifter isn't named on the mortgage, then the mortgage lender will require they sign an Occupier Waiver. This allows the mortgage lender to repossess the property, making the parents homeless, with them having no legal right to stop it.
- 3
Divorce
If the owner of the house divorces, their share of the property will be included in the assets declared as part of the divorce. The risk is that the property must be sold or that orders must be issued to make it usable only by one of the divorcees. This risk could happen in the future, even if the child isn't married at the time of the gift.
Expert Tip - Do not ignore the Pre-Owned Assets Tax?
Failing to file the Pre-Owned Assets Tax (POAT) return is treated by HMRC as a failure to declare income, which triggers a combination of automatic penalties, interest, and potential "failure to notify" charges. Because POAT is an annual income tax, it is subject to the standard HMRC penalty regime for Self Assessment, which can be severe if left unaddressed.
Penalties
Violation | Penalty Detail |
Late Filing | £100 immediate fine. After 3 months, £10 per day (up to £900). After 6 months, a further 5% of the tax due or £300 (whichever is greater). |
Late Payment | 5% of the unpaid tax after 30 days, 6 months, and 12 months. |
Interest | HMRC charges interest on any unpaid tax and penalties. As of 2026, the late payment interest rate is historically high (Base Rate of 3.75% + 4%). |
HMRC Behavioural Penalties
The penalties don't stop with the above. HMRC distinguishes between an honest mistake and a deliberate attempt to hide the benefit. The penalty is a percentage of the total tax you should have paid:
- Careless Error: 0% to 30% of the tax lost (if you tell them voluntarily).
- Deliberate but not Concealed: 20% to 70% of the tax lost.
- Deliberate and Concealed: 30% to 100% of the tax lost (this applies if you actively tried to hide the arrangement from HMRC).

Summary: When gifting property and still living in it
Whilst the goal is to give your property to your children, if the reality is that you'll still be living in that property, here is a critical checklist for you to consider.
- Check your connection: Check to see if you are connected to the person/people you are gifting your property to.
- Do you share the property with your child: If you share the property with your children, living and ownership, then you may avoid the POAT rules..
- Total gift or just undervalued: Decide if you need any money from the transfer, or if this is an outright gift.
- Do you share the property: Instead of a complete gift, you could share living and owning the property with your children and avoid the POAT.
- Pay Fair Market Rent: You can pay the new owners a fair market rent to allow you to live in the property; or
- Pay POAT: To pay and declare the Pre-Owned Assets Tax (POAT), you must include it in your annual Self Assessment tax return. Filed no later than the 31st January (online); or
- Opt out of POAT: To opt out, you must file your Form IHT500 by the 31st January in the tax year you dispose of the property.
- Consider care home fees: You could fall foul of the Care Home Act if you knowingly deprive the council of assets when calculating your care home needs.
- Consider insolvency rules: The transfer could be reversed if you are insolvent.
- Consider the risks: Where would you live if the person you have gifted the property to becomes bankrupt, is repossessed, or divorces?
- Consider other taxes:
- Stamp Duty Land Tax: Generally, Stamp Duty Land Tax (SDLT) is not payable on a gift where no money changes hands. However, if there is an outstanding mortgage on the property and the child takes over the debt, SDLT may be charged on the value of that mortgage.
- Capital Gains Tax: If you have rented out your home during your ownership, you could still be liable for CGT when you dispose of it.
