Charged SDLT twice? Relief for a duplicate stamp duty demand
HMRC may appear to charge stamp duty twice on one property deal, and you can ask it to remove the duplicate charge. It is unusual.
Still, it can matter a great deal when two tax demands relate to the same purchase.
What this rule is about
SDLT normally follows a land transaction return. A true double charge should therefore be rare.
Still, mistakes can happen. The key question is simple: do the two amounts really concern the same SDLT matter?
What the official source says
HMRC’s manual says that, if you think it assessed you more than once for the same transaction, you can make a written claim to HMRC. HMRC must decide the claim. If it refuses, you may appeal.
- The two charges must concern the same matter.
- You must ask for relief from the duplicate charge.
- The claim route is for a claim outside a return.
What this means in practice
Two letters do not always mean HMRC charged tax twice; one may replace, amend or correct the other. Read both notices before you pay a second amount.
- Match the property and transaction reference on each notice.
- Check the amount, date and reason given for each charge.
- Keep proof of any SDLT already paid.
How to analyse it
Start with the paperwork, not the label on the letter. A duplicate demand means HMRC charged the same tax twice, not simply that you received two communications.
- Identify each amount HMRC says is due.
- Link each amount to the property deal concerned.
- Check whether one notice cancels or changes the other.
- Explain clearly why the remaining charges overlap.
Example
After filing his return, Amir paid £8,000 SDLT.
He then receives a further assessment for £8,000 that identifies the same property deal and gives no different reason. If it is a second charge for that same tax, he can claim relief against it.
Why this can be difficult in practice
People can get this wrong. Similar amounts do not prove a double charge, because HMRC may have changed an earlier figure or may be dealing with a different issue.
- A later notice may be an adjustment, not a second bill.
- The documents may use different references for one deal.
- The supplied guidance gives no specific deadline for this claim.
Key takeaways
- Double SDLT charges are rare, but relief is available.
- Compare both notices with your return and payment record.
- HMRC guidance is not law; the legislation controls the claim.

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 current legal position after 17 November 2025 has not been verified against an official current legislation source.
- Whether two demands concern the same matter can depend on the documents and the reason for each demand.
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.
- Both tax demands or assessments.
- The land transaction return and SDLT payment records.
- The transaction reference, property details and completion documents.
- HMRC letters explaining why each amount was charged.
