Does SDLT higher rates apply when you buy the remaining share of your main home after inheriting a minority interest?

Introduction

A common Stamp Duty Land Tax question arises where someone already owns a small inherited share in the home they live in and then decides to buy the rest of it. The issue becomes more complicated if they also own another residential property, such as a buy-to-let. In that situation, many people worry that the purchase will be treated as an “additional dwelling” and attract the SDLT higher rates.

The answer depends on the detailed rules in Schedule 4ZA to the Finance Act 2003. In some cases, an inherited share can be ignored when testing whether the higher rates apply. That can make the difference between paying standard residential SDLT rates and paying the surcharge.

The Question

The scenario is this:

• The buyer owns a minority share in a dwelling that has been their only or main residence for many years.
• That minority share was inherited on a death.
• The buyer is now purchasing the remaining share in that same dwelling.
• The buyer also owns another residential property which has been let out and has never been used as their residence.

The question is whether buying the remaining share in the main home triggers the SDLT higher rates, and whether it matters that the existing share was inherited rather than bought.

Nick’s Explanation

Nick’s reasoning was that the key rules are found in Schedule 4ZA to the Finance Act 2003. He explained that the higher rates apply only if the statutory conditions are met, including the condition that, at the end of the day of the transaction, the buyer owns a major interest in another dwelling and the purchase is not a replacement of an only or main residence.

He then pointed to the special rule for inherited interests. In anonymised form, his view was:

Where the buyer inherited an interest of no more than 50% in a dwelling on death, and the purchase takes place within three years of the date of death, that inherited interest is disregarded when deciding whether the buyer owns another dwelling for the higher rates test.

On that basis, he concluded that the inherited minority share in the main home would be ignored for the relevant test, so the purchase of the remaining share would not be treated as a higher rates transaction. He also noted that the inheritance point is central to the result.

The Law

The SDLT higher rates for additional dwellings are governed by Schedule 4ZA to the Finance Act 2003.

Under paragraph 1(1), a transaction is a higher rates transaction if Conditions A to D are met.

In broad terms:

• Condition A, in paragraph 2(1), requires the main subject-matter of the transaction to consist of a major interest in a single dwelling.
• Condition B, in paragraph 2(2), requires chargeable consideration of at least £40,000.
• Condition C, in paragraph 2(3), looks at whether, at the end of the day of the transaction, the purchaser owns a major interest in another dwelling.
• Condition D, in paragraph 2(4), asks whether the purchased dwelling is not a replacement for the purchaser’s only or main residence.

If those conditions are met, the higher residential rates apply.

There is then an important relieving provision for inherited interests. Paragraph 9(1)(a) of Schedule 4ZA provides that, for deciding whether Condition C is met, an interest in a dwelling is disregarded if:

• the purchaser became entitled to it on the death of a person,
• the effective date of the chargeable transaction is within the period of three years beginning with the date of death, and
• the interest does not exceed 50%.

Standard residential SDLT rates are then charged under section 55 Finance Act 2003 if the higher rates do not apply.

Analysis

The rules should be applied step by step.

1. The buyer is acquiring the remaining share in a dwelling. That is capable of being a chargeable transaction involving a major interest in a dwelling, so the higher rates rules must be considered.

2. The buyer also owns another dwelling, namely the let property. That means there is a real possibility that Condition C could be met.

3. However, the buyer’s pre-existing share in the main home was inherited, is below 50%, and the purchase takes place within three years of the death. That brings paragraph 9(1)(a) into play.

4. Because paragraph 9(1)(a) says that such an inherited interest is to be disregarded when determining whether Condition C is met, the inherited minority share is ignored for that part of the higher rates test.

5. That means the purchase of the remaining share is not treated in the same way as buying an additional dwelling merely because the buyer already had that inherited minority interest.

6. The fact that the buyer owns a separate let property does not, by itself, change the effect of the inherited-interest disregard in relation to the inherited share in the main home.

7. The “replacement of only or main residence” rules in paragraph 3 are not the main route to the answer here. This is because the buyer is not selling an old main residence and replacing it with another. Instead, the stronger point is that the inherited minority interest is specifically disregarded under paragraph 9(1)(a).

So the inheritance point is not incidental. It is the reason the surcharge does not apply on these facts.

Outcome

Where a buyer inherited no more than a 50% share in their home, and within three years of the death buys the remaining share, the inherited interest can be disregarded for the higher rates test under paragraph 9(1)(a) of Schedule 4ZA Finance Act 2003.

On those facts, the purchase of the remaining share in the buyer’s only or main residence should be charged at the standard residential SDLT rates rather than the higher rates.

The fact that the buyer also owns a separate let property does not change that result in this type of case.

Practical Steps

• Check the exact date of death and the effective date of the purchase to make sure the transaction falls within the three-year period required by paragraph 9(1)(a).
• Confirm that the inherited share did not exceed 50%.
• Keep probate and title documents showing that the existing share arose on death rather than by purchase or transfer during lifetime.
• Make sure the SDLT return is prepared on the basis that the higher rates do not apply, if the statutory conditions for disregard are satisfied.
• Ask the conveyancer to review Schedule 4ZA paragraph 9(1)(a) specifically, rather than looking only at the general “additional dwelling” rules.
• Where there is any unusual feature, such as multiple linked transactions, trusts, mixed-use elements, or timing issues, check the position carefully before filing the SDLT return.

Conclusion

If you inherited a minority share of 50% or less in the home you live in, and you buy the rest within three years of the death, the inherited share is normally ignored for the SDLT higher rates test. In that situation, the purchase of the remaining share in your main home should usually be taxed at standard residential SDLT rates, not the higher rates.
