Claim a Refund for Overpaid Land Transaction Tax in Wales
Claiming a refund for overpaid Land Transaction Tax
You can ask the Welsh Revenue Authority for a refund if you paid too much Land Transaction Tax even though the original return was correct. This is only for overpayments of tax already paid, not for changing or correcting the return itself.
- You can use this refund route only where the LTT return was correct but the amount paid was too high.
- A claim can be made by the buyer, the solicitor or conveyancer who acted on the original purchase, or another person authorised to act for the buyer.
- You should gather all details before starting the online form because it cannot be saved and finished later.
- You will usually need the transaction details, the 12-digit UTRN, the refund amount, and the bank details for the repayment.
- Claims normally take around 15 to 20 working days, but may take longer if the Welsh Revenue Authority asks for more information.
- The main issue is making sure this is a true overpayment case, rather than a situation where the original return needs to be amended.

How to claim a refund if you overpaid Land Transaction Tax
This page explains when and how you can ask the Welsh Revenue Authority for a refund if you paid too much Land Transaction Tax after submitting a correct return. The key point is that this route is for overpayment where the return itself was correct, but the amount paid was higher than it should have been.
What this rule is about
Land Transaction Tax, or LTT, is the tax that applies to land transactions in Wales. After a transaction is reported, the amount due is paid to the Welsh Revenue Authority.
Sometimes a buyer may end up paying more than the correct amount of tax even though the LTT return filed for the transaction was correct. In that situation, the Welsh Revenue Authority provides an online refund process.
This matters because the refund process described here is not a general correction route for every kind of mistake. It is specifically aimed at cases where the return was correct but there has still been an overpayment.
What the official source says
The Welsh Revenue Authority says you can use its online form if:
- you have submitted a correct LTT return, and
- you paid more LTT than you should have paid.
The people who can apply are:
- the buyer of the property charged
- a solicitor or conveyancer acting for the buyer in the original purchase
- another person authorised to act for the buyer
The authority says claims usually take 15 to 20 working days to process, although this can take longer if further information is needed.
The online form cannot be saved part-way through, so the information should be gathered in advance.
What this means in practice
In practical terms, this is an administrative refund claim for overpaid tax where the filed return does not itself need correcting. The focus is on the amount paid, not on changing the original return.
You should therefore first ask a basic question: was the return correct at the time it was submitted? If the answer is yes, but the tax paid exceeded what should have been paid, this refund route may be the right one.
The Welsh Revenue Authority expects the claim to identify the original transaction and the amount to be refunded, and to provide payment details for the refund.
If a solicitor, conveyancer, or other representative is making the claim, they must be acting for the buyer. In the case of someone other than the original solicitor or conveyancer, the source indicates that they must be authorised to act.
How to analyse it
A sensible way to approach this is to work through the following points:
- Check whether the original LTT return was correct. This refund route is only described for correct returns.
- Identify the overpayment amount. You will need to state the amount of tax to refund.
- Confirm who is making the claim. It must be the buyer, the buyer’s solicitor or conveyancer from the original purchase, or another authorised person acting for the buyer.
- Gather the transaction details, including the 12-digit unique transaction reference number, or UTRN.
- Make sure you have the correct bank account and sort code details for the person who should receive the refund.
- Prepare all information before starting, because the online form cannot be saved and completed later.
The information the Welsh Revenue Authority says you will need is:
- your details
- the lead buyer’s details, if different from your own
- details of the original transaction
- the 12-digit UTRN
- the amount of tax to refund
- bank account and sort code details for the recipient of the payment
Example
Illustration: a buyer’s LTT return was submitted correctly for a purchase in Wales. Later, it becomes clear that the amount actually paid to the Welsh Revenue Authority was higher than the amount that should have been paid under that correct return. In that case, the buyer, the original conveyancer, or another authorised representative can use the Welsh Revenue Authority’s online refund form to claim back the overpaid amount.
Why this can be difficult in practice
The main practical difficulty is identifying whether the problem is truly an overpayment on a correct return, or whether the real issue is that the return itself needs to be changed. The source material only deals with the first situation.
Another point that can cause delay is incomplete information. The Welsh Revenue Authority says processing may take longer if it needs more information, so it is important that the claim clearly identifies the transaction and the amount said to be repayable.
There can also be an authority point where someone other than the buyer is submitting the claim. If the claimant is not the buyer or the solicitor or conveyancer acting in the original purchase, they will need to be authorised to act for the buyer.
Key takeaways
- This refund route is for overpaid LTT where the original return was correct.
- The claim can be made by the buyer, the original solicitor or conveyancer, or another authorised person acting for the buyer.
- Have all details ready before starting the online form, including the UTRN, refund amount, and payment details.
