Stamp duty refund after selling your old home

You may be able to claim a refund after selling your old main home, where you paid higher SDLT rates because that sale had not completed when you bought your new home.
- The full replacement-home test still applies.
- The sale date and SDLT filing date both matter.

Stamp duty refund after selling your old home
If you paid extra stamp duty because you still owned your old home, you may be able to get that extra amount back after you sell it. The sale must qualify. Act before the deadline.
What this rule is about
Sometimes a move does not happen in the neat order people expect. You buy your new home first, but your old one sells later. On the day you buy, you own both homes.
That can mean paying the higher SDLT rates at first. SDLT means stamp duty land tax. It is not necessarily the final answer, though.
The law can treat the new home as a replacement for your old main home once the old home is sold. If that happens, the extra tax paid because of the delay may be repaid.
What the official source says
HMRC’s manual says that someone who paid the higher rates because of Condition D may claim a refund after selling their previous main residence. Condition D is the part of the test which asks whether the new home was replacing the buyer’s only or main home.
Legislation permits amendment after a qualifying later sale. A filing date means the last day allowed for sending in that return.
- You must have paid the higher SDLT rates when buying the new home.
- You must later sell your previous main home.
- You must meet the wider legal test for the new home to count as a replacement.
- For the usual rule, the old home must be sold within the allowed three-year period.
- The old home must have been your only or main home at some point during the relevant three years.
- You must claim within the time limit that applies to the sale.
For a sale on or after 29 October 2018, HMRC says the deadline is the later of these two dates: 12 months after selling the old home, or 12 months after the filing date for the SDLT return on the new home.
For a sale on or before 28 October 2018, its manual gives a different first deadline: three months after the sale, or 12 months after the filing date, if that is later.
What this means in practice
You may need to pay the higher amount first, even if you expect to sell your old home soon. Once that sale completes, check whether the refund conditions and deadline are met.
This is the part people miss: the clock runs from a legal date. Later HMRC contact cannot extend it. Delayed sale money cannot extend it.
- Keep the SDLT return for your new home.
- Record the completion date of the old home’s sale.
- Check the filing date shown for the SDLT return.
- Keep documents that show you lived in the old home.
- Use HMRC’s repayment service to make the application.
How to analyse it
Start with the order of events. The key question is not simply whether you owned two homes. It is whether the later sale makes your new home a replacement under the full statutory test.
- When did you buy the new home?
- Did you intend to live in that home as your only or main home?
- Which property did you sell afterwards?
- Had you lived in that property as your only or main home?
- Did the sale happen within the permitted period?
- What was the filing date for the SDLT return on the new home?
- Which of the two possible claim deadlines falls later?
It helps to write down the dates before applying. A sale date and a filing date can lead to different deadlines. The later one is the date that matters under the normal post-28 October 2018 rule.
Example
Amir buys a new home while his old home is still on the market. He pays the higher SDLT rates because he owns both homes at that point. He later sells the old home on 1 November 2018.
Assume the filing date for Amir’s SDLT return was 31 December 2018. Twelve months after the sale is 1 November 2019. Twelve months after the filing date is 31 December 2019. HMRC’s deadline is 31 December 2019.
That example only deals with timing. Amir would still need the facts to show that the old home was his main home and that the new home qualifies as its replacement.
Why this can be difficult in practice
A later sale is important, but it is not the whole test. The facts about where you lived and what you intended can matter just as much.
You might think the address on a bill settles the issue. It does not. The question is about the property that was really your only or main home.
- Buyers may confuse the date of exchange with the date the sale completed.
- People may overlook the filing date for the original SDLT return.
- A former rental property may not meet the main-home part of the test.
- Joint ownership or a spouse or civil partner can change the analysis.
- Historic sales have a different deadline in HMRC’s manual.
Key takeaways
- A later sale can allow a refund of higher SDLT rates.
- The old home must meet the main-home replacement test.
- For sales from 29 October 2018, use the later of the two 12-month deadlines.
