Is SDLT payable on an inherited property if you pay off the mortgage and fund a charitable legacy?

Introduction

People often ask whether Stamp Duty Land Tax (SDLT) can arise when they inherit a property under a will but then take on financial obligations connected with the estate. A common concern is whether paying off an existing mortgage, or raising a new mortgage to meet estate liabilities such as a charitable gift, could count as chargeable consideration for SDLT.

This issue matters because SDLT is charged on land transactions where there is chargeable consideration, but not every transfer of property is a taxable purchase. Where a property passes by inheritance, the starting point is very different from an ordinary sale.

The Question

A married couple inherit the residue of an estate under a will. The residue includes a house subject to an existing mortgage. The estate also includes a cash gift to a charity, and the couple plan to keep the house as a rental property rather than live in it.

To deal with the estate liabilities, they intend to raise a new buy-to-let mortgage over the inherited house. The new borrowing would be used partly to repay the existing mortgage and partly to fund the charitable legacy required by the will.

The question is whether any of the following create SDLT liability:

• the inheritance of the house itself;
• taking the property subject to the existing mortgage;
• repaying that mortgage;
• raising a new mortgage over the inherited property; or
• paying the charitable legacy from funds raised against the property.

Nick’s Explanation

Nick’s view was that no SDLT should arise on these facts.

In summary, his reasoning was:

• property passing under a will is generally exempt from SDLT;
• an existing mortgage can count as chargeable consideration in a purchase context, but inheritance is not a purchase;
• creating a new mortgage over land already owned is not itself a chargeable land transaction for SDLT; and
• a payment made to satisfy a charitable gift under the will is not consideration given for the acquisition of the land.

As Nick explained in substance, the beneficiaries are not acquiring the house in exchange for paying money. They receive it under the will, and the later payment to the charity is simply part of carrying out the deceased’s testamentary instructions. On that basis, it is not chargeable consideration “for the land”.

The Law

SDLT is governed by Part 4 of the Finance Act 2003.

The main provisions relevant here are:

• Finance Act 2003, section 49 — SDLT applies to land transactions unless an exemption applies.
• Finance Act 2003, Schedule 3 — certain transactions are exempt, including acquisitions on death under a will or intestacy.
• Finance Act 2003, section 50 — SDLT is charged by reference to chargeable consideration.
• Finance Act 2003, Schedule 4 — sets out what counts as chargeable consideration.
• Finance Act 2003, Schedule 4, paragraph 8 — where a purchaser takes land subject to an existing debt secured on the land, that debt may count as chargeable consideration.
• Finance Act 2003, section 48(2)(a) — excludes a security interest from being treated as a land transaction in its own right.

The key legal distinction is between:

• a person acquiring land by inheritance; and
• a person acquiring land by purchase, gift subject to debt, or some other transaction involving consideration.

Inheritance is not treated in the same way as a purchase. That is why the mortgage rules in Schedule 4, paragraph 8 do not automatically create SDLT in every case where land is subject to secured debt.

Analysis

Step 1: The house passes under the will.

Where a dwelling devolves on beneficiaries under a will, that acquisition is generally exempt from SDLT under Schedule 3 FA 2003. The beneficiaries are not buying the property from the estate. They are receiving it because of the deceased’s will.

Step 2: Consider whether the existing mortgage changes that result.

In an ordinary purchase, taking land subject to an existing mortgage can amount to chargeable consideration under Schedule 4, paragraph 8. But that rule applies where there is a purchaser and a purchase transaction. In an inheritance case, the beneficiaries are not purchasers. The property vests in them through the estate, not by contract in return for value.

So, the fact that the property is mortgaged does not, by itself, turn the inheritance into a chargeable transaction.

Step 3: Consider the repayment of the existing mortgage.

Repaying the old mortgage is simply the discharge of secured debt affecting the inherited property. It is not consideration given to acquire the land. The beneficiaries already have the property under the will. The repayment does not create a new land transaction for SDLT purposes.

Step 4: Consider the new buy-to-let mortgage.

Granting a mortgage over land already owned is not itself a chargeable land transaction. SDLT is concerned with acquisitions of chargeable interests in land, not with the mere creation of a security interest. Section 48(2)(a) FA 2003 makes that clear.

That means the new mortgage, taken out after the inheritance, does not itself trigger SDLT.

Step 5: Consider the charitable legacy.

The most important question is whether the money paid to the charity could be treated as consideration for the house. On these facts, the better view is no.

The beneficiaries are not paying the charity in exchange for the property. The charitable gift is a separate obligation arising under the will. Even if the beneficiaries raise funds against the inherited house in order to satisfy that obligation, the payment remains a legacy payable out of the estate structure, not consideration for the acquisition of the land.

Step 6: Consider whether keeping the property as a rental changes anything.

It does not change the SDLT analysis of the inheritance itself. The intended use of the inherited property as a let property may matter for other tax issues, but it does not convert an exempt inheritance into a chargeable purchase.

Step 7: Distinguish this from “uninhabitable” dwelling cases.

Sometimes SDLT questions arise because a taxpayer hopes to avoid residential rates on the basis that a property was not suitable for use as a dwelling. That is a different issue from inheritance. In any event, the threshold for showing that a property is not suitable for use as a dwelling is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. That authority does not alter the inheritance analysis here, but it is important where readers are considering habitability arguments in other SDLT disputes.

Outcome

On the facts described, the practical conclusion is that no SDLT should arise:

• the inheritance of the house is exempt;
• the existence or discharge of the old mortgage does not create chargeable consideration in an inheritance case;
• the new buy-to-let mortgage is not a chargeable land transaction; and
• the payment of the charitable legacy is not consideration for the acquisition of the house.

Practical Steps

If you are assessing a similar situation, the sensible steps are:

• check the will carefully to confirm that the property passes under the will rather than under a separate bargain or deed of arrangement;
• identify whether any payment is truly being made in exchange for the land, or whether it is simply an estate liability or legacy;
• separate the inheritance event from any later refinancing, because refinancing land you already own is usually outside the SDLT charge;
• review whether there has been any variation of the will or any separate agreement between beneficiaries that could alter the SDLT position;
• keep estate papers, mortgage redemption figures, and the will available in case the SDLT treatment later needs to be explained; and
• if the facts are more complicated, such as a deed of variation, appropriation by personal representatives, or payments between beneficiaries, obtain specific SDLT advice.

Conclusion

Where a property is inherited under a will, SDLT does not usually arise simply because the property is mortgaged or because the beneficiaries refinance it to meet estate obligations. On the facts considered here, paying off the old mortgage and funding a charitable legacy do not amount to chargeable consideration for the property, so the inheritance remains outside the SDLT charge.
