Claiming an LTT refund more than 12 months after buying
If you bought property or land in Wales more than 12 months ago, you cannot change your original Land Transaction Tax return. You may nevertheless claim a refund if you think you paid too much. This is not stamp duty: it is the Welsh tax known as LTT.
What this rule is about
LTT mistakes have two correction routes. Early on, you can amend the return. After that period, the route changes. You make a separate refund claim instead.
That distinction matters because the WRA can check the claim before repaying any money. A refund may be available. It is not automatic.
What the official source says
The Welsh Revenue Authority, or WRA, says that people cannot amend a return after 12 months, while someone who believes they overpaid can still make a refund claim. That route remains available.
- You must be outside the 12-month return amendment period.
- You must think that too much LTT was paid on the purchase.
- You must explain why you believe there was an overpayment.
- The WRA says you will usually need to claim within four years of buying.
- The WRA can check the claim before paying a refund.
What this means in practice
You may still correct an old return through a refund claim. Although it may be too late to edit the return itself, that does not always end the matter if you can make a reasoned refund claim. You need a reasoned claim.
- Use the refund-claim route, not an amendment to the old return.
- Set out the error clearly rather than simply asking for money back.
- Keep the return and papers that support your explanation.
- Expect the WRA to ask questions if the claim appears incorrect.
- Do not expect payment while the WRA is still checking.
How to analyse it
Begin with the dates. Then consider the reason for the claimed overpayment. The four-year guide matters, but the official page describes it as the usual limit. The exact statutory deadline may require closer calculation.
- Confirm the date you completed the purchase.
- Check whether more than 12 months have passed.
- Review the original LTT return and tax calculation.
- Identify the specific reason you say too much tax was paid.
- Work out the refund amount you are claiming.
- Explain the point and retain documents that support it.
Example
Amir bought land in Wales 18 months ago. He later finds information that makes him think he overpaid LTT by £1,200. He cannot amend the old return. Instead, he may make a refund claim if he explains the reason for it and provides material supporting the £1,200 figure. The WRA may check the claim before paying anything.
Why this can be difficult in practice
The process changes after 12 months. Calling it an amendment when it is really a claim can delay matters. Timing needs care too, especially when a purchase is close to the usual four-year limit.
- A belief that tax was overpaid is not, by itself, an explanation.
- The WRA may write to you before deciding whether the claim is correct.
- If it opens an enquiry after submission, it has 12 months from the day after submission to do so, even while it considers the claim. That limit matters.
- The WRA processes any refund due only after it has finished the check.
Key takeaways
- After 12 months, use a refund claim rather than an amended return.
- Explain clearly why you think you overpaid LTT.
- Make the claim promptly and keep evidence for any WRA check.

Official guidance
The pages below are the Welsh Revenue Authority’s guidance. Guidance is not law. It sets out how the Welsh Revenue Authority 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. the Welsh Revenue Authority can also change or withdraw guidance, and it may not cover your facts.
Where this is not settled
- The exact deadline can depend on the type of claim and the relevant statutory dates. The official page gives a usual four-year guide rather than every possible calculation.
- The supplied statutory materials do not record a currency date, so the current legal position should be checked before relying on it.
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.
- a copy of the original LTT return
- the completion date for the purchase
- a clear explanation of why too much tax was paid
- documents supporting the amount requested
