Understanding Stamp Duty on Gifted Property

Gifting a property to a family member might seem like a straightforward act of generosity, but it comes with important tax considerations that many families overlook. Chief among these is Stamp Duty Land Tax (SDLT). Understanding when SDLT applies, when it does not, and what triggers a liability is essential before any property transfer takes place.

What is Stamp Duty Land Tax?

Stamp Duty Land Tax is a tax charged by HMRC on the purchase or acquisition of property and land in England and Northern Ireland. It applies to “chargeable consideration,” which broadly means money or money’s worth paid in exchange for a property. In Scotland, an equivalent tax called Land and Buildings Transaction Tax (LBTT) applies, with a nil-rate threshold of £145,000 for residential property. In Wales, the equivalent is Land Transaction Tax (LTT), with a threshold of £225,000.

The key principle: no money changes hands, no SDLT is due. It is when a mortgage or debt enters the picture that things become more complex.

Is SDLT Payable on a Gifted Property?

In most cases, no. A pure gift, where a property is transferred by gift deed with no money changing hands and no outstanding mortgage being assumed by the recipient, carries no SDLT liability. This applies whether the property is gifted to children, grandchildren, other relatives, or unrelated individuals. As long as the transfer is genuinely gratuitous, with no payment, no debt assumed, and no services exchanged, SDLT is nil.

HMRC does require that such transfers are properly documented. Typically, this means completing a formal TR1 transfer deed declaring nil consideration, signed by both parties and registered at HM Land Registry. Where no SDLT is due, an SDLT1 return is not generally required, but records should be kept in case HMRC queries the transaction.

When Does a Gift Trigger an SDLT Liability?

The position changes entirely when the gifted property carries an outstanding mortgage. If the recipient takes on the outstanding mortgage as part of the gift, HMRC treats the value of that assumed debt as chargeable consideration. SDLT therefore becomes payable on the amount of the mortgage assumed, even though no cash was paid.

The nil-rate band of £125,000 (from 1 April 2025) still applies, meaning small mortgage amounts may not generate any SDLT liability. However, larger mortgages will trigger a charge under the standard residential rates:

The SDLT liability falls on the recipient, not the donor. The recipient is treated as the purchaser for SDLT purposes, and the return and payment must be made within 14 days of the effective date of the transaction.

The Additional Dwelling Surcharge

If the recipient already owns a property when they receive a gifted property, the additional dwelling surcharge applies. From 1 April 2025, this surcharge is set at 5% on top of the standard residential rates:

This surcharge can significantly increase the SDLT bill. For example, a recipient who already owns property and assumes a £300,000 mortgage on a gifted home would pay substantially more than a recipient receiving their first property.

Gifting Property to Spouses and Civil Partners

A common misconception is that transfers between spouses are always SDLT-free. This is not the case. The only SDLT exemption for spouses and civil partners applies to court-ordered divorce transfers, not voluntary gifts between married couples. If one spouse gifts a mortgaged property to the other, SDLT is due on the mortgage amount assumed, exactly as with any other gift. Outside of divorce proceedings, the standard gift rules apply in full.

Gifting vs Inheriting: Key Differences

The route through which a property is received makes a significant difference to SDLT. Properties inherited on death are never subject to SDLT, even if an outstanding mortgage transfers with them. In contrast, mortgage assumption on a gifted property during a person’s lifetime is fully chargeable. This distinction has real estate planning implications: a heavily mortgaged property is generally better left until death if the intention is for a family member to receive it, as the inheritance route eliminates any SDLT on the debt.

Other Taxes to Consider

SDLT is not the only tax exposure when gifting property. The donor may face Capital Gains Tax (CGT) on any increase in the property’s value since it was originally purchased, as HMRC treats a gift as a disposal at full market value. The exception is gifts between spouses or civil partners living together, which are treated as no gain, no loss transactions. Inheritance Tax (IHT) may also be a consideration. Lifetime gifts of property are only exempt from IHT if the donor survives seven years from the date of the gift. If the donor dies within three to seven years, tapered IHT rates apply.

A Note on the Annual IHT Gift Allowance

The annual IHT gift allowance of £3,000 per person is frequently misunderstood in the context of property gifting. Many families believe using this allowance reduces or eliminates SDLT. It does not. The IHT gift allowance is relevant only to inheritance tax planning and has no effect whatsoever on an SDLT liability. SDLT and IHT are entirely separate taxes assessed independently.

Transferring Property to a Company

When a property is transferred from an individual to a connected company, SDLT is calculated on the market value of the property at the date of transfer, regardless of the consideration actually paid. This applies where the individual is connected to the company, or where the company pays for the property with shares in whole or in part. Professional advice is essential before structuring any such transfer.

How UK Property Tax Accountants Can Help

Navigating SDLT on gifted property involves more than simply knowing whether a tax is due. The calculation depends on whether a mortgage exists, who the recipient is, what other properties they own, and how the transfer is structured. Getting it wrong can result in an unexpected and significant tax bill.

We review mortgage liabilities, the recipient’s existing property portfolio, and whether the additional dwelling surcharge applies, so there are no surprises on completion. We also consider the wider picture, including CGT exposure for the donor and IHT planning, to ensure the gift is structured in the most tax-efficient way possible. Whether you are gifting to children, transferring to a spouse, or moving property into a company structure, our team provides clear, practical advice tailored to your specific circumstances.
