Surcharge Refund Eligibility Checker

Five quick yes/no questions. If you answer yes to all of them, you can apply to HMRC for a refund of the additional-property surcharge.

  1. 1

    Did you pay the 5% additional-property surcharge on the new home?

    You will see this on the SDLT1 return as the higher rate (HRAD) calculation. If you bought before 31 October 2024 the surcharge was 3%.

  2. 2

    Is the new home your only or main residence?

    You must have moved in (or intend to move in) and treat it as your main home. Letting it out or keeping a different address as your main residence disqualifies you.

  3. 3

    Have you sold (or are you about to sell) your previous main residence?

    Time runs from completion to completion. You need to sell within 36 months of buying the new home.

  4. 4

    Will the sale complete within 36 months of the new purchase?

    The 36-month window is strict. There is no extension.

  5. 5

    Will you apply within 12 months of the sale of the previous home?

    The 12-month application deadline is also strict. Calendar it on the day the old home completes.

This is a quick triage tool, it does not capture every edge case (Mesher orders, divorce situations, overseas property nuances). For anything material, talk to your conveyancer or a tax adviser. Read the full refund guide for context.
