Do higher rates of SDLT apply if a company I am involved with owns a flat?

Introduction

A common SDLT question is whether owning, directing or holding shares in a company that owns residential property means you are treated as owning that property personally. This matters because the higher rates of Stamp Duty Land Tax can apply when a buyer already has a major interest in another dwelling at the end of the day of the purchase.

People often search for this issue when buying a home jointly, especially where one buyer has a history of previous ownership and the other is a first-time buyer, or where one of them is connected with a property-holding company. The answer usually turns on who legally or beneficially owns the other dwelling.

The Question

A buyer is purchasing a dwelling for £525,000 with their spouse. The spouse is a first-time buyer. The buyer has owned and sold a home in the past but does not currently own any residential property personally.

The buyer is also one of several directors of a private limited company. That company owns a flat and the mortgage is in the company’s name. The question is whether the company-owned flat causes the buyer’s new purchase to be charged at the higher residential SDLT rates, or whether only the standard residential rates apply.

Nick’s Explanation

Nick’s central point was that the higher rates under Schedule 4ZA Finance Act 2003 apply only if, at the end of the effective date of the transaction, the purchaser has a major interest in another dwelling.

In anonymised form, his reasoning was:

“A person is treated as having a major interest only if they own the dwelling in their own name or have a beneficial interest in it. If the other property is owned by a company, and the mortgage is also in the company’s name, being a director or shareholder does not by itself make the individual the owner for Schedule 4ZA purposes.”

He therefore concluded that, provided the buyer does not personally own any other residential property and has no separate beneficial interest in the company’s flat, the higher rates do not apply. On that basis, the purchase is charged at the ordinary residential rates under section 55 Finance Act 2003.

Using the standard rates for a £525,000 purchase, the calculation given was:

• 0% on the first £125,000 = £0
• 2% on the next £125,000 = £2,500
• 5% on the remaining £275,000 = £13,750

Total SDLT: £16,250

The Law

SDLT on residential property is charged under Part 4 of the Finance Act 2003. The amount payable is generally worked out under section 55 FA 2003, using the residential rate bands in force at the effective date of the transaction.

The higher rates for additional dwellings are contained in Schedule 4ZA FA 2003. In broad terms, those higher rates apply if the relevant conditions are met at the end of the day of the purchase. One of the key conditions is that the purchaser has a major interest in another dwelling.

Schedule 4ZA looks at the purchaser’s own property interests. The fact that a separate legal person, such as a company, owns a dwelling does not automatically mean the individual director or shareholder owns that dwelling. A company has its own legal personality. Its assets are not normally treated as the personal assets of its directors or shareholders.

Whether a person has a “major interest” depends on the legislation, including the rules in Schedule 4ZA and the wider framework in FA 2003. In practical terms, the key question is whether the individual personally holds a legal or beneficial interest in another dwelling. Merely managing the company, being a director, or owning shares in it is not usually enough on its own.

Analysis

Step 1: Identify the purchasers.

The purchase is being made by two individuals jointly. SDLT treatment must be considered by reference to the purchasers and the rules applying to joint buyers.

Step 2: Check whether either purchaser personally owns another dwelling at the end of the day of completion.

On the facts given, one spouse is a first-time buyer and does not appear to own another dwelling. The other spouse previously owned a property but no longer holds any residential property personally.

Step 3: Consider the company-owned flat.

The flat is owned by a private limited company. The mortgage is also in the company’s name. That points strongly to the company, not the individual director, being the owner of the flat.

Step 4: Ask whether the buyer nevertheless has a personal beneficial interest in that flat.

This is the important legal distinction. If the buyer has no trust interest, no direct personal ownership and no separate beneficial entitlement to the flat itself, then the company’s ownership is not attributed to the buyer merely because they are a director or shareholder.

Step 5: Apply Schedule 4ZA.

If the buyer does not personally hold a major interest in another dwelling, the condition for the higher rates is not met on these facts. That means the additional surcharge should not apply.

Step 6: Calculate SDLT at the standard residential rates.

On the figures provided, the SDLT comes to £16,250 using the ordinary residential rates referred to in the explanation above.

Step 7: First-time buyer relief does not alter the result here.

Although one spouse is a first-time buyer, relief for first-time buyers is not available where the purchase is made jointly and one of the purchasers is not a first-time buyer. So the transaction falls to be taxed at the normal residential rates rather than first-time buyer rates.

Outcome

On these facts, the practical conclusion is that the purchase should not be subject to the higher rates for additional dwellings merely because one buyer is a director of a company that owns a flat.

If neither buyer personally owns another dwelling at the end of the day of purchase, and there is no personal beneficial interest in the company-owned flat, the SDLT is payable at the standard residential rates.

For a purchase price of £525,000, that produces SDLT of £16,250 on the rate structure used in the explanation.

Practical Steps

If you are assessing a similar purchase, it is sensible to work through the following points:

• Confirm who the legal purchasers are.
• Check whether either purchaser personally owns any other dwelling at completion.
• If a company owns a dwelling, confirm that the company is the legal owner and that the individual does not hold the property on trust or otherwise have a personal beneficial interest in it.
• Check whether any first-time buyer relief claim is possible. In a joint purchase, all buyers generally need to qualify.
• Ask your conveyancer to review Schedule 4ZA FA 2003, especially paragraphs 3 to 6, if there is any doubt about whether another property interest counts.
• Keep company records and title documents available in case HMRC or your conveyancer asks why the company-owned property should not be treated as your own.

If a buyer is instead arguing that another property should be ignored because it was uninhabitable or not suitable for use as a dwelling, that is a different issue. The condition thresholds are now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799.

Conclusion

Being a director of a company that owns a flat does not, by itself, make you the owner of that flat for higher rates SDLT purposes. If you do not personally own another dwelling and have no beneficial interest in the company’s property, the purchase is generally taxed at the standard residential rates rather than the higher rates.
