Stamp duty refund after selling your old home
Refunds after selling an old home
The HMRC page is archived, so the legislation is the key source. A later sale of a former main home may allow an SDLT return to be amended.
- Check the replacement-home conditions
- Check the sale and amendment deadlines

Stamp duty refund after selling your old home
This HMRC page is archived and contains no live directions for getting back extra stamp duty on a second home. Rather than that old page, the legislation sets the route where you bought a new main home before selling the old one.
What this rule is about
You may have paid the higher SDLT rates because you still owned your former home on the day you bought the new one. A later sale can change that result.
Timing matters, but it is not timing alone.
What the official source says
Marked as archived and redundant, the supplied HMRC page offers no active claim process or checklist. It therefore cannot settle whether you can get money back.
Where you bought a new main home before selling the old one, legislation provides a narrow route under which the new home may count as replacing your main home after the later sale. That route is limited.
- You intended to live in the new home as your only or main home.
- You sold a major interest in your former home.
- Neither you nor a spouse or civil partner kept that interest after the sale.
- The former home was your only or main home at some point in the three years before purchase.
What this means in practice
If those conditions are met, you can amend the SDLT return to reflect the later sale. That is the statutory route to recover SDLT that was overpaid.
- The normal sale period is three years, starting the day after purchase.
- The amendment deadline is 12 months after the sale, or the return filing date if later.
- Exceptional and unforeseeable events may allow a longer sale period.
How to analyse it
Work through the dates and facts in order. Do not assume that selling the old home is enough by itself.
- Confirm when you bought the new home.
- Check your intention for that home on that date.
- Check when the old home was sold.
- Check whether it had been your main home.
- Work out the amendment deadline.
Example
Nadia buys a new home on 3 April and plans to live there. She sells her old main home the following September and keeps no interest in it. Provided the other conditions are met, she can amend her SDLT return within the statutory deadline.
Why this can be difficult in practice
An archived manual title does not fill the gaps. Your use of each home, along with any spouse or civil partner interest, can decide the result.
- A sale outside the normal period does not automatically end the matter.
- An extension needs exceptional circumstances that could not reasonably have been foreseen.
- The extension application has its own 12-month deadline after the sale.
Key takeaways
- The archived HMRC page gives no current claim instructions.
- A later sale can change the higher-rate SDLT result.
- Dates, home use and the return deadline all matter.
Technical analysis
For advisers, and for anyone who wants to check the law behind this page. You do not need this section to understand the guidance above.
Legislation
- FA 2003 Schedule 4ZA para 3 — later sale of a former main home; the permitted period for a later sale; applying for an exceptional circumstances extension
- FA 2003 Schedule 4ZA para 8 — deadline for amending the SDLT return
Where this is not settled
- The archived HMRC page does not explain how its former refund process operated.
- Whether a home was an only or main residence depends on the facts.
Evidence you would need
This kind of case is decided on the facts of the individual property. These are the records that usually settle it, and the ones an adviser would ask you for.
- Completion dates for the new-home purchase and old-home sale
- Evidence of the intention to live in the new home
- Evidence that the old home was an only or main residence
- Records showing no interest in the old home remained after sale
