Stamp duty overpayment claims after HMRC takes recovery action
Stamp duty overpayment claims after HMRC takes recovery action
If HMRC has started legal recovery action for unpaid stamp duty, an overpayment claim may arrive too late, and the same result can follow if you agree a settlement after that action begins. Timing can decide everything.
What this rule is about
Overpayment relief lets you ask HMRC to repay stamp duty land tax, or SDLT, that was not due. It can also apply where HMRC says you must pay an amount that you believe is not due.
But that route has limits. Case F is one. It stops people from reopening a tax debt through an overpayment claim after enforcement or settlement has dealt with it.
Timing matters. A claim that was possible earlier may be blocked once recovery action ends.
What the official source says
The legislation says HMRC does not have to give effect to a claim when enforcement proceedings brought by HMRC caused the amount to be paid, or require it to be paid. The rule also applies when you and HMRC settle those proceedings by agreement.
HMRC’s manual takes a different practical point. Before judgment or settlement, a person can still make a claim if all the other conditions are met. That is guidance, not the law.
- There must be an amount of SDLT paid, or said to be due.
- HMRC must have brought proceedings to enforce payment of that amount.
- The exclusion applies if payment follows those proceedings.
- It also applies if payment follows an agreement settling them.
- A claim must still be made within four years of the transaction’s effective date.
What this means in practice
A reminder letter does not necessarily end the road. Ask whether HMRC has actually started proceedings to enforce payment, rather than simply asked you to pay.
Case F can block overpayment relief for an amount once enforcement action, or a settlement of that action, fixes the amount. Paying first may not keep the repayment route open forever.
- Keep every HMRC letter, notice and email.
- Check whether HMRC has issued a formal assessment or determination.
- Identify the date any recovery proceedings began.
- Read any proposed settlement carefully before accepting it.
- Check the four-year claim limit separately.
How to analyse it
Start with the amount you want HMRC to repay or cancel. Then build a simple timeline. What happened first can decide whether Case F matters.
- Was SDLT paid, or has HMRC said that it is due?
- Why do you say the amount was not due?
- Has HMRC started proceedings to enforce that specific amount?
- Did you make an agreement with HMRC to settle those proceedings?
- Was your claim made within four years of the transaction’s effective date?
- Could another exclusion prevent overpayment relief?
Example
Amir paid £18,000 in SDLT. HMRC later says a further £6,000 is due and starts legal recovery action for it. Amir agrees to pay the £6,000 to settle that action.
If he later says that £6,000 was never due, Case F may stop HMRC having to give effect to an overpayment claim for that settled amount. That result may follow.
Now change one fact: Amir makes his claim before any settlement is agreed and before a judgment is given. HMRC’s manual says he may still make the claim, but it must meet the other conditions, including the four-year limit.
Why this can be difficult in practice
People can miss this point: not every contact from HMRC counts as enforcement proceedings. A demand for payment, a warning, and formal recovery action are different things. The paperwork and dates matter.
A settlement may cover more than one amount or issue, so you need to match the amount in the proposed claim with the amount covered by the proceedings or agreement. Check each amount.
- People may confuse a payment request with formal recovery action.
- A settlement may settle only part of the tax dispute.
- Case F may apply even where the amount has not yet been paid.
- The four-year limit can independently prevent a claim.
Key takeaways
- Case F can block overpayment relief after HMRC enforcement proceedings.
- A settlement of those proceedings can have the same effect.
- Check the documents, dates and four-year limit before treating a claim as available.

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 a particular letter, demand or contact amounts to enforcement proceedings depends on what HMRC actually did and the documents issued.
- The bundled statutory text is current only to 17 November 2025. The law must be checked against the current official legislation for events after that date.
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.
- HMRC assessments or determinations showing the amount claimed
- letters and formal documents showing whether legal recovery action began
- any agreement settling HMRC’s recovery action
- proof of payment and the transaction’s effective date
