Do you pay SDLT on a shared ownership purchase if a partner owned a home many years ago?

Introduction

A common concern for couples buying through a shared ownership scheme is whether an old property interest will trigger higher rates of Stamp Duty Land Tax (SDLT). This often comes up where one buyer owned a home in the distant past, especially if that interest ended as part of a divorce settlement. The key question is usually whether that past ownership still counts at the time of the new purchase.

The Question

A couple who have been renting for many years are buying a shared ownership home for £255,000. One partner previously owned a home with a former spouse more than 20 years ago, but transferred that interest away under a divorce settlement and has had no ownership interest in that property since. They want to know whether SDLT is payable, and in particular whether the 5% higher rates for additional dwellings could apply.

Nick’s Explanation

Nick’s view was that, on these facts, it is very unlikely that the 5% higher rates of SDLT apply.

He explained that the higher rates in Schedule 4ZA to the Finance Act 2003 apply only if, at the end of the effective date of the transaction, a purchaser owns a major interest in another dwelling and is not replacing their only or main residence.

In his words, the important point is that the former ownership “ceased entirely”. The fact that the earlier transfer happened under a divorce settlement, and the person received no profit from it, does not alter the SDLT analysis. What matters is whether that person still owns a major interest in another dwelling at completion. If they do not, the surcharge should not apply on that basis.

Nick also noted that for a shared ownership purchase at £255,000, the SDLT result depends partly on whether the buyer makes a market value election under Schedule 9 Finance Act 2003. If a market value election is made, standard residential rates apply to the full market value. On the figures given, that would mean 0% on the first £250,000 and 5% on the next £5,000, producing SDLT of £250. If no market value election is made, and SDLT is charged only on the premium paid for the initial share, the SDLT may be nil depending on the value of that initial share.

The Law

The main provisions are in the Finance Act 2003.

Section 55 FA 2003 sets out the standard residential SDLT rates.

Schedule 4ZA FA 2003 contains the higher rates for additional dwellings. Paragraph 3(1) is central. Broadly, the higher rates apply if, at the end of the effective date of the transaction, the purchaser owns a major interest in another dwelling and the purchase is not a replacement of the purchaser’s only or main residence.

For shared ownership, special rules apply under Schedule 9 FA 2003. A buyer may in some cases make a market value election so that SDLT is charged upfront by reference to the full market value of the property. If no market value election is made, SDLT may instead be charged on the premium for the initial share and potentially on later staircasing transactions, depending on the statutory rules. Section 70(5A) FA 2003 is also relevant in this area.

Analysis

The issue can be worked through in stages.

First, ask whether either buyer will own another dwelling at the end of the day of completion. That is the core test for the higher rates under Schedule 4ZA.

Second, look at the old property interest. If one buyer owned a home many years ago but transferred their entire interest to a former spouse as part of a divorce settlement, and has owned no residential property since, that earlier ownership does not by itself trigger the surcharge. A past ownership is not enough. The legislation looks at what is owned at the effective date of the new transaction.

Third, whether that earlier transfer produced a financial gain is not relevant to this question. SDLT higher rates do not depend on whether the person made a profit when they gave up the previous property. They depend on whether the person still owns a major interest in another dwelling when the new purchase completes.

Fourth, because this is a shared ownership purchase, the amount of SDLT under the standard rates depends on how the transaction is structured for SDLT purposes. If the buyer makes a market value election under Schedule 9, SDLT is calculated on the full market value. On a market value of £255,000, and using the rates stated in Nick’s explanation, that produces SDLT of £250.

Fifth, if there is no market value election, SDLT may instead be calculated only on the premium paid for the initial share. In some cases that means no SDLT is payable at the outset, because the initial premium falls below the relevant threshold. The exact figure depends on the value of the share actually being acquired now.

Nothing in the facts suggests an uninhabitable or unsuitable-for-use issue, but where readers are considering that argument generally, the threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799.

Outcome

On the facts described, the old home ownership that ended more than 20 years ago under a divorce settlement should not cause the 5% higher rates to apply, provided the buyer no longer owns any interest in that or any other dwelling at completion.

That means the purchase should usually fall under the standard residential SDLT rules, not the additional dwelling surcharge rules.

For a shared ownership purchase with a full market value of £255,000, the SDLT may be:

• £250 if a market value election is made and the full market value is taxed upfront; or

• possibly nil at the outset if no market value election is made and the initial share premium is below the SDLT threshold.

Practical Steps

Before exchange or completion, a buyer should check the following:

• Whether either buyer owns any current legal or beneficial interest in another dwelling anywhere in the world.

• Whether the earlier property interest was fully transferred away, with no retained share.

• Whether the shared ownership lease allows or requires consideration of a market value election under Schedule 9 FA 2003.

• What premium is being paid for the initial share, as this affects SDLT if no market value election is made.

• Whether the conveyancer or SDLT adviser has correctly considered Schedule 4ZA and Schedule 9 FA 2003.

It is also sensible to keep documents showing that the previous property interest ended, such as the divorce settlement or transfer paperwork, in case the SDLT position ever needs to be evidenced.

Conclusion

If a buyer once owned a home but gave up that ownership completely many years ago under a divorce settlement, that past ownership will not normally trigger the SDLT higher rates on a new shared ownership purchase. The main SDLT question then becomes whether tax is due under the standard rules, and that depends in part on whether a market value election is made.
