Overpayment relief when you can amend your SDLT return
You cannot use overpayment relief for stamp duty if another formal route can correct the error. For example, you may need to amend your SDLT return instead.
What this rule is about
Overpayment relief is a route for asking HMRC to repay stamp duty that you did not owe, or cancel an amount it says you must pay. It is not always the route you can choose.
Ask whether a further step under the SDLT rules can resolve the issue.
What the official source says
HMRC’s internal manual says you must use another formal way to recover the overpayment or reduce the bill, rather than overpayment relief. It gives amending a land transaction return as an example.
- Another formal SDLT route may be available.
- A return amendment may provide that route.
- If it does, HMRC says you should use it instead.
What this means in practice
Rather than choosing a claim form first, work out which legal route fits your situation. The route can decide whether HMRC considers your request.
- Check the return you sent to HMRC.
- Identify the error and why it changed the tax.
- Check whether you can amend the return.
How to analyse it
Work through the options in order. Keep copies of the return and documents that support the correction.
- Was the stamp duty amount wrong?
- Can a formal SDLT step correct it?
- Is that step still open?
- If not, does overpayment relief remain available?
Example
Sam paid £8,000 in stamp duty after sending a return. Sam later finds an error that a return amendment can correct. HMRC’s view is that Sam should amend the return instead of seeking overpayment relief.
Why this can be difficult in practice
Whether they paid too much is often people’s main focus. That matters, but it is not the whole answer. You also need to identify the right way to correct it.
- An overpayment does not automatically mean this claim route works.
- Dates and the type of error can determine which route is available.
- HMRC’s manual explains its view, but the legislation is the law.
Key takeaways
- Check other SDLT routes first.
- A return amendment may come before overpayment relief.
- Keep evidence for the corrected position.

Official guidance
The pages below are HMRC’s guidance. Guidance is not law. It sets out how HMRC reads the legislation, and it is not binding on you, on a tribunal or on a court. Where guidance and the legislation differ, the legislation wins. HMRC can also change or withdraw guidance, and it may not cover your facts.
Where this is not settled
- Whether an amendment or another formal route remains open will depend on the dates and facts of the individual case.
- Current legislation should be checked if the point concerns law after 17 November 2025.
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.
- the submitted land transaction return
- the reason the stamp duty was overpaid
- dates showing whether another correction route remains open
- documents supporting the corrected tax position
