Welsh Land Transaction Tax enquiry: WRA may ask for documents and let you correct underpaid tax
If the Welsh Revenue Authority checks your Land Transaction Tax return, it may ask questions and request documents. If your return shows too little tax, you may get a chance to correct it. That can be better than leaving an error unresolved.
What this rule is about
An enquiry is WRA’s check of the information in a tax return, and it can involve more than a simple email exchange when further details are needed. WRA says it may ask for information and, in some cases, visit your property or business premises.
This matters because Land Transaction Tax in Wales is Land Transaction Tax, or LTT. The figures on your return still matter while WRA is checking them.
What the official source says
WRA says it will ask for information during an enquiry. If the tax in an LTT return is lower than it should be, you may have an opportunity to amend the return to show the extra tax due.
- WRA may ask you to provide information.
- It may visit a property or business premises in some cases.
- You may be able to amend an LTT return if it understates the tax.
- You can contact WRA if you do not understand a request.
What this means in practice
Read each request carefully and match it to the return you filed; if a figure needs support, show why it is right, and if it needs correction, identify that. Keep your reply focused on what WRA has asked for.
- Find the return, completion papers and supporting records.
- Check whether the amount of tax on the return is correct.
- Compare any proposed change with the facts of the purchase.
- Ask WRA to explain a request that you do not understand.
How to analyse it
Begin with the return rather than by guessing what WRA wants. Then work through the evidence. A clear timeline often helps.
- What exact point does WRA want explained?
- What information or document supports the answer?
- Does that evidence show that more LTT is due?
- Has WRA offered a way to amend the return?
- Does the proposed amendment match the facts and figures?
Example
Rhodri receives an enquiry about his LTT return. WRA asks for information about a figure in it. After checking the papers, Rhodri finds that the tax shown is too low. WRA gives him the opportunity to amend the return so it reflects the extra tax due. The enquiry can then consider the corrected figure.
Why this can be difficult in practice
People sometimes treat an information request as proof that they have done something wrong. It is not. It means WRA needs more information before it reaches a view.
In practice, the difficulty is often locating the right documents and seeing why a particular question is relevant.
- A visit is possible, but the official page does not say when one will happen.
- An opportunity to amend is not the same as an automatic right to make any change.
- A change made during an enquiry may be dealt with when WRA closes that enquiry.
Key takeaways
- WRA may request information during an LTT enquiry.
- You may be able to correct a return that shows too little tax.
- Ask WRA to explain a request you do not understand.

Official guidance
The pages below are the Welsh Revenue Authority’s guidance. Guidance is not law.

Where this is not settled
- The supplied official page does not explain when WRA will visit, what information it will request, or how it will make an amendment available.
- The skill bundle does not contain the requested currency notice, so the current status of the statutory material should be checked before publication.

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 enquiry notice and any questions from WRA
