Why a missed stamp duty relief claim may block a refund
If you paid too much stamp duty because you did not make a relief claim or election, overpayment relief may not fix it. That can matter even where the tax result now looks plainly wrong.
What this rule is about
Overpayment relief lets you ask HMRC to repay stamp duty land tax that was not due. It does not give you a general second chance to make every choice you missed first time.
An election is a formal tax choice. A claim is a formal request for a tax treatment or relief.
What the official source says
HMRC’s manual points to the Case A exclusion. The legislation says HMRC does not have to give effect to an overpayment relief claim where too much tax resulted from a mistake about a claim or election.
- The mistake may be in a claim or election that was made.
- It may be making or giving a claim or election incorrectly.
- It may be failing to make or give a claim or election.
What this means in practice
You cannot simply add a missed relief later through an overpayment relief claim. Instead, you may need to use the original claim or election process.
- Check whether the relief needed a formal claim or election.
- Check what was included with the SDLT return.
- Keep proof of what was sent and when.
How to analyse it
Start with the reason the tax was too high. The label on your request does not decide the answer.
- Identify the relief or election you say should have applied.
- Read its rules as they applied on the transaction date.
- Work out whether a claim or election was required.
- Check whether the problem was an error, an omission, or something else.
Example
Nadia pays £8,000 of stamp duty. Later, she finds that a relief might have reduced that bill, but she did not make a relief claim. If Nadia paid the excess because she missed that claim, Case A prevents overpayment relief from requiring HMRC to repay it. Whether HMRC can accept a late claim is a separate question.
Why this can be difficult in practice
This is the part people often miss: being overcharged and having an available refund process are different things. The exact relief rules and the documents filed can decide the result.
- A late claim may have its own rules and limits.
- HMRC’s manual mentions limited discretion, but does not set out those limits here.
Key takeaways
- A missed claim can block overpayment relief.
- Check the original relief process first.
- HMRC guidance is not the law.

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
- The supplied source does not explain the conditions on which HMRC may accept a late claim or election.
- Whether a particular form, statement or omission is a claim or election will depend on the relevant relief rules and 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.
- the SDLT return and tax calculation
- copies of any claim, election or correspondence sent
- the relief rules relied on at the transaction date
- evidence showing when and how documents were submitted
