Will higher rate SDLT apply if I move from a trust-owned home into a new family home while I still own buy-to-let properties?

Introduction

This is a common Stamp Duty Land Tax question where someone is buying a new home but already has interests in other properties. The difficulty usually lies in whether the purchase counts as a replacement of an only or main residence, and whether any existing property interests trigger the higher residential rates for additional dwellings.

The issue becomes more complicated where the current home is held in a trust, where inherited properties are involved, or where some rental properties are owned personally and others through a company. In those situations, the answer depends on the exact legal nature of the buyer’s interests at the effective date of the purchase.

The Question

A buyer is purchasing a new home jointly with a spouse and a parent who will all live there together. Part of the purchase money comes from the parent selling their former home.

The buyer currently lives in a dwelling owned by a family trust. The buyer is a trustee and has a right to occupy the property for life, but says there is no beneficial ownership apart from those occupation rights.

The buyer also personally owns several buy-to-let properties, has one rental property held through a company, and has inherited minority shares in several other dwellings jointly with family members. The question is whether the higher rate of SDLT applies, and whether the fact that the parent is replacing their own main residence changes the result.

Nick’s Explanation

Nick’s reasoning was that the key question is not simply whether the new property will become the family’s main home. The real question is whether, at the time of purchase, any of the joint buyers:

• holds a major interest in another dwelling, and
• is not replacing their own only or main residence.

He explained that if the buyer does not own a major interest in the trust property, then moving out of that property does not amount to disposing of a previous main residence for SDLT purposes.

He also identified that personally owned buy-to-let properties are likely to trigger the higher rates if the buyer is not replacing a previous main residence in the statutory sense.

In anonymised form, his conclusion was:

Because the buyer does not own a major interest in the current home, leaving that property does not count as replacing a main residence. The personally owned buy-to-let properties therefore bring the purchase within the higher rates unless some other qualifying disposal has taken place.

Nick also noted that inherited property interests can sometimes be ignored for a limited period. In this scenario, a minority inherited share may be disregarded for three years from the date of death under Schedule 4ZA.

On the parent’s position, he pointed out that the fact the parent has sold their previous home does not automatically save the transaction if another joint purchaser still meets the higher-rate conditions. If one buyer is caught, the whole joint purchase is taxed at the higher rates.

The Law

The higher residential rates of SDLT are contained in Schedule 4ZA to the Finance Act 2003. They apply where a chargeable transaction involves a major interest in a dwelling and, broadly, the purchaser already owns another dwelling and is not replacing an only or main residence.

The main provisions relevant here are as follows:

• Section 55 Finance Act 2003: the general charging provision and SDLT rates.
• Section 117(2) Finance Act 2003: defines a “major interest” in land, broadly a freehold or leasehold estate.
• Schedule 4ZA Finance Act 2003: sets out the higher rates for additional dwellings.
• Paragraph 3 Schedule 4ZA: companies are generally subject to the higher residential rates on dwelling purchases.
• Paragraph 9(3) Schedule 4ZA: certain inherited interests are disregarded for three years from the date of death.
• Section 103 Finance Act 2003: joint purchasers are jointly and severally liable, and in practice the higher-rate test is applied by reference to the purchasers collectively so that if one purchaser is caught, the transaction is charged at the higher rates.
• Section 53 Finance Act 2003: market value rule for certain connected person transactions.
• Section 43 Finance Act 2003: companies acquiring chargeable interests can be subject to SDLT even where the transfer is part of an internal or connected arrangement.

For the replacement of only or main residence exception, the buyer must usually show both:

1. the new dwelling is intended to be the buyer’s only or main residence, and
2. the buyer disposed of a previous only or main residence within the permitted three-year period.

The disposal must be of a major interest. Simply moving out of a property that the buyer occupied, without owning a major interest in it, is not enough.

Analysis

The position can be worked through in stages.

First, the new property is clearly intended to be a home. That helps with the first limb of the replacement test, but it does not by itself prevent the higher rates.

Second, the current trust property appears not to be owned by the buyer beneficially or legally, apart from the buyer being a trustee and having occupation rights. On those facts, the buyer may not hold a major interest in that dwelling for SDLT purposes. If that is right, leaving that property does not amount to disposing of a previous only or main residence.

That point is crucial. SDLT replacement relief is concerned with the disposal of a major interest in the former main residence. Occupation alone is not enough.

Third, the buyer personally owns several buy-to-let properties. Those are major interests in dwellings. If the buyer still owns them at the effective date of the new purchase, and the buyer is not replacing a previous only or main residence in the statutory sense, the higher rates are likely to apply.

Fourth, the inherited minority shares in other dwellings may be ignored temporarily. Paragraph 9(3) Schedule 4ZA can disregard certain inherited interests for three years from the date of death. If the purchase completes within that three-year period, those inherited shares may not count for the higher-rate test. That may help, but it does not solve the problem created by the personally owned buy-to-let properties.

Fifth, the parent’s sale of their own former home does not necessarily prevent the higher rates. In a joint purchase, the rules are applied by reference to the purchasers as a whole. If one purchaser owns other dwellings and is not replacing their own main residence, the entire transaction can still be taxed at the higher rates.

Sixth, moving buy-to-let properties into a company is not a simple workaround. A transfer of residential property to a connected company is itself usually a chargeable transaction for SDLT purposes. The company is generally subject to the higher residential rates under paragraph 3 of Schedule 4ZA, and market value may be substituted under section 53 Finance Act 2003. So that step may create an SDLT charge rather than eliminate one.

Seventh, there may be cases where a property can become a buyer’s only or main residence before disposal, but this depends heavily on the facts. There is no fixed statutory minimum occupation period in SDLT law. HMRC would look at whether the occupation was genuine, using evidence such as council tax, utility bills, electoral roll registration and the overall pattern of occupation. Any attempt to rely on that route would need careful factual support.

Finally, if anyone is considering arguing that a dwelling was not suitable for use as a dwelling at the relevant time, the threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. A property will not fall outside the dwelling rules merely because it needs repair or modernisation. The condition must be serious enough to meet that stricter standard.

Outcome

On the facts described, the higher rate of SDLT is likely to apply to the joint purchase.

The main reason is that the buyer appears not to be disposing of a major interest in their current trust-occupied home, so they are probably not replacing a previous only or main residence for SDLT purposes. At the same time, they still personally own buy-to-let dwellings, which are major interests in other residential properties.

The parent’s replacement of their own main residence does not, on its own, prevent the higher rates from applying to the whole transaction.

The inherited minority shares may be temporarily ignored if the purchase falls within the three-year inheritance window, but that does not remove the effect of the personally owned buy-to-let properties.

Practical Steps

Anyone in a similar position should check the following before exchange or completion:

1. Confirm the exact legal and beneficial interest in the current home. If it is trust-owned, obtain the trust deed and any occupation documents to establish whether there is a major interest.
2. List every dwelling interest owned personally at the effective date, including partial shares and inherited interests.
3. Check whether any inherited dwelling interests fall within the three-year disregard in paragraph 9(3) Schedule 4ZA.
4. Identify whether any rental properties are owned personally or by a company. Personally owned properties are particularly important for the higher-rate test.
5. Do not assume that another joint buyer’s sale of their own home will fix the SDLT position for everyone else.
6. If considering transferring properties to a company, calculate the SDLT cost of that transfer first, including any market value issues for connected parties.
7. If considering whether a property has become a main residence, gather objective evidence of genuine occupation.
8. Where suitability for use is relevant, assess the condition carefully against the stricter approach confirmed in Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799.

Conclusion

If you move from a trust-owned home in which you only have occupation rights, that will not usually count as replacing a previous main residence for SDLT. If you still personally own buy-to-let dwellings when you buy the new home, the higher residential rates will usually apply, even if another joint purchaser has sold their own former home.
