Can You Rent Out Your Old Home and Still Get the SDLT Higher Rates Refund?

Introduction

Many buyers pay the higher rates of Stamp Duty Land Tax (SDLT) when they buy a new home before selling their previous one. A common question is whether the extra SDLT can still be refunded if the old home is let out before it is sold.

This matters because the refund rules are tied to replacing a main residence. People often move into a new home first, keep the old one for a period, and may want to rent it out while deciding when to sell. The key issue is whether that temporary letting prevents a refund of the higher rates surcharge.

The Question

A homeowner buys a new dwelling while still owning their current home. Because they now own more than one dwelling at the end of the purchase day, the higher rates of SDLT apply to the new purchase.

The homeowner then wants to keep the former home for a period, rent it out, and sell it later, but still within three years of buying the new home. The question is whether renting out the former home during that period stops them from claiming a refund of the higher rates surcharge.

Nick’s Explanation

Nick’s answer was that renting out the former home does not, by itself, prevent a refund.

He explained that the relevant rule is in Schedule 4ZA to the Finance Act 2003. In anonymised form, his reasoning was:

“If the old property was the purchaser’s only or main residence within the three years before buying the new one, and the purchaser disposes of that old residence within three years after the new purchase, the higher rates surcharge can be reclaimed. The legislation does not say that the old property must stay empty or remain owner-occupied in the meantime. Renting it out does not affect eligibility, provided the statutory conditions are met.”

He also noted that the refund claim must be made within the statutory time limit after the sale of the former home.

The Law

The higher rates of SDLT for additional dwellings are contained in Schedule 4ZA to the Finance Act 2003.

Where a purchaser buys a dwelling and, at the end of the effective date of the transaction, owns another dwelling, the higher rates may apply unless a specific exception is met.

One important exception concerns the replacement of a purchaser’s only or main residence. If the old main residence has not yet been sold when the new home is bought, the higher rates are usually paid first, with a possible refund later if the old main residence is disposed of within the required period.

The key provision referred to in the explanation is paragraph 3(6)–(7) of Schedule 4ZA FA 2003, which states:

“Condition D is that in the period of 3 years beginning with the effective date of the later transaction—
(a) the purchaser has disposed of the purchaser’s previous main residence, and
(b) at some time in the period of 3 years ending with the effective date of the later transaction the purchased dwelling was the purchaser’s only or main residence.”

In practical terms, the legislation requires two broad things:

• the former property must have been the purchaser’s only or main residence at some point in the three years before the new purchase; and
• the former main residence must be disposed of within three years after the new purchase.

The legislation does not impose a separate rule saying that the former home cannot be rented out before sale.

Analysis

The issue can be worked through step by step.

First, if a person buys a new home while still owning their previous home, the higher rates will usually apply on the purchase of the new property.

Second, that is not necessarily the end of the matter. The law recognises that many people replace their main home in two stages: they buy first and sell later.

Third, to obtain a refund, the old property must genuinely have been the buyer’s previous only or main residence. This is a factual question. It is not enough that the buyer merely owned it. It must have been their home.

Fourth, the old main residence must then be disposed of within three years beginning with the effective date of the purchase of the new property. A sale 2.5 years later is still within that three-year window.

Fifth, the old property can be rented out before it is sold without automatically breaking the refund conditions. The statutory test looks at whether it was the previous main residence within the relevant three years before the new purchase, and whether it is disposed of within three years after that purchase. It does not say that interim letting defeats the claim.

So, where a buyer moves into a new home, lets the former home for two years, and then sells it after 2.5 years, the letting itself does not stop the refund claim, assuming the old property really was the buyer’s previous main residence and all timing requirements are met.

The claim deadline also matters. The refund must be claimed within 12 months of the sale of the former home, or within 12 months of the filing date for the SDLT return for the new purchase, whichever is later.

Although not directly in issue here, readers sometimes confuse this refund question with arguments about whether a property was uninhabitable or not suitable for use as a dwelling. That is a different area of SDLT law. In any uninhabitable or not suitable for use case, the threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799.

Outcome

Yes. In general, renting out the former home before selling it does not stop a refund of the SDLT higher rates surcharge.

If the former property was your only or main residence within the three years before you bought the new one, and you sell that former residence within three years after buying the new one, you can usually claim the refund. Letting the property in the meantime does not, on its own, prevent that result.

Practical Steps

If you are checking your own position, work through the following points:

• Confirm that the old property was genuinely your only or main residence at some point during the three years before the new purchase.
• Check the effective date of the new purchase, as this starts the three-year disposal window.
• Make sure the sale of the former home completes within that three-year period.
• Keep evidence showing that the old property was your main residence, such as council tax records, electoral roll details, utility bills, and correspondence address history.
• Do not assume that renting out the old property prevents a claim; the main issue is whether the statutory residence and timing conditions are met.
• Submit the refund claim to HMRC within 12 months of the sale of the former home, or within 12 months of the filing date of the SDLT return for the new purchase, whichever is later.

Conclusion

A temporary let of your former home does not usually block an SDLT higher rates refund. The important questions are whether that property was your previous main residence and whether you dispose of it within the statutory three-year period after buying the new home.
