Can first-time buyers reclaim SDLT if standard rates were paid by mistake?

Introduction

Many buyers discover after completion that Stamp Duty Land Tax (SDLT) was charged at the standard residential rates even though they appear to qualify for first-time buyer’s relief. A common question is whether that overpayment can be reclaimed from HMRC.

This issue matters because the difference can be substantial. Where a purchase completed after 1 April 2025 and the buyers met the statutory conditions for first-time buyer’s relief, SDLT may have been reduced or even eliminated entirely. If standard rates were paid instead, the buyer may be able to amend the SDLT return and claim a refund.

The Question

A married couple bought their first home for £425,000. The purchase completed after 1 April 2025, and the solicitor’s completion statement showed SDLT charged at the standard residential rates. The couple say they had never previously owned a dwelling anywhere in the UK or abroad, and they had signed paperwork stating that they were first-time buyers. They want to know whether they can reclaim the SDLT overpayment.

Nick’s Explanation

Nick’s reasoning was that the SDLT shown on the completion statement matched the standard rates that applied from 1 April 2025. On a purchase price of £425,000, the calculation would be:

• 0% on the first £125,000 = £0
• 2% on the next £125,000 = £2,500
• 5% on the remaining £175,000 = £8,750

That produces total SDLT of £11,250.

Nick then compared that with the first-time buyer rules in Finance Act 2003 Schedule 6ZA. He explained, in substance, that where qualifying first-time buyers purchase a dwelling for no more than £625,000 and intend to occupy it as their only or main residence, the first £425,000 is charged at 0%, with 5% applying only to the slice between £425,001 and £625,000.

On those figures, if the couple qualified, no SDLT should have been payable at all because the price was exactly £425,000. That meant the possible reclaim was £11,250.

Nick also focused on the key factual checks. In anonymised form, his point was:

• why the standard rates were applied instead of first-time buyer’s relief;
• whether either buyer had ever owned a residential property in the UK or overseas;
• whether the purchase was intended to be the buyers’ main residence.

He further noted that ownership through a limited company does not normally count as personal ownership for first-time buyer relief purposes, provided the statutory conditions are otherwise met.

The Law

The relevant relief is first-time buyer’s relief under Finance Act 2003 Schedule 6ZA.

In broad terms, the relief applies where:

• the transaction is a purchase of a major interest in a single dwelling;
• the purchase price does not exceed the statutory threshold for the relief;
• the purchaser, or if there is more than one purchaser, each purchaser, is a first-time buyer;
• the purchasers intend to occupy the dwelling as their only or main residence.

A person is not a first-time buyer if they have previously acquired a major interest in a dwelling, whether in the UK or elsewhere. This overseas element is important and often overlooked. Previous ownership abroad can prevent the relief just as much as previous ownership in England, Wales, Scotland or Northern Ireland.

For completions on or after 1 April 2025, the rates referred to in Nick’s explanation were:

• standard residential rates: 0% to £125,000, 2% from £125,001 to £250,000, and 5% from £250,001 to £925,000;
• first-time buyer’s relief: 0% on the first £425,000 and 5% on the portion from £425,001 to £625,000, provided the purchase price does not exceed £625,000.

If an SDLT return was filed incorrectly, the buyer may be able to correct it by amending the return within the statutory amendment window or, depending on timing and circumstances, by making a repayment claim to HMRC.

Analysis

Applying those rules step by step:

1. The purchase price was £425,000. That is within the price cap for first-time buyer’s relief.

2. The dwelling was bought as the buyers’ home, so the main residence condition appears capable of being met.

3. There were two purchasers. Because of that, both had to qualify. If even one of them had previously owned a dwelling anywhere in the world, the relief would fail for the whole transaction.

4. On the facts given, both buyers say they had never owned residential property in the UK or abroad. If that is correct, they appear to satisfy the first-time buyer condition.

5. If the relief applied, SDLT on a £425,000 purchase should have been £0.

6. Instead, standard SDLT of £11,250 was paid. That points to an overpayment of £11,250.

The main practical issue is therefore not the rate calculation but proof of eligibility. HMRC will usually want the position clearly stated and supported by the transaction documents. Relevant material often includes:

• the SDLT return as filed;
• the completion statement or solicitor’s financial statement;
• the purchase deed or transfer;
• the buyers’ declaration or questionnaire confirming first-time buyer status;
• any correspondence showing the relief should have been claimed.

If the return was simply submitted on the wrong basis, that is usually capable of correction.

Outcome

On the facts described, the couple appear to have a strong basis for reclaiming the SDLT paid in error.

If they genuinely had never owned a dwelling anywhere in the world before this purchase, and the property was bought as their only or main residence, first-time buyer’s relief should have applied. For a £425,000 purchase completing after 1 April 2025, that would mean SDLT of £0 rather than £11,250.

The likely overpayment is therefore £11,250, subject to checking the filed return and confirming that neither buyer had any prior qualifying ownership interest.

Practical Steps

If you are in this position, the sensible next steps are:

1. Obtain the SDLT5 certificate or a copy of the SDLT return that was submitted to HMRC.

2. Check the effective date of the transaction, usually completion, because the rates depend on when the purchase completed.

3. Confirm whether every purchaser had ever owned a major interest in a dwelling anywhere in the world, even many years ago and even outside the UK.

4. Review whether the property was intended to be occupied as the buyers’ only or main residence.

5. Gather supporting documents, including the completion statement, transfer deed, and any first-time buyer declaration signed during conveyancing.

6. Ask for the SDLT return to be amended or a repayment claim to be prepared and submitted to HMRC, depending on the procedural route available.

If the issue is whether a property was uninhabitable or not suitable for use as a dwelling, readers should note that the threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. That is a different line of argument from first-time buyer’s relief, but it is sometimes raised in SDLT refund cases. The courts now require genuinely serious defects before a property will fall outside the normal dwelling rules.

Conclusion

Where first-time buyers paid standard SDLT by mistake on a qualifying purchase, a refund may be available. On a £425,000 purchase completing after 1 April 2025, eligible first-time buyers should have paid no SDLT at all. If standard rates were paid instead, the overpayment can be significant and should be checked promptly against the statutory conditions and the filed SDLT return.
