What you need for a Welsh Land Transaction Tax refund claim
Gather the key details from the original purchase before starting a Land Transaction Tax refund form. Land Transaction Tax is Wales’s form of stamp duty. Having these details ready can make the form much easier to complete.
What this rule is about
This official source is a checklist for a claim form. It tells you what information the form needs, not whether you qualify for a refund or how much you should receive.
What the official source says
You will need details about the people involved, the original transaction, the refund amount and where payment should go.
- Your own details.
- Details of the lead buyer, if they are different from yours.
- Details of the original land transaction.
- A 12-digit unique transaction reference number, known as the UTRN.
- Your requested tax refund amount.
- Bank account and sort code details for the person who will receive payment.
What this means in practice
Rather than guessing from memory, find the records from the original transaction first. Because it identifies that transaction, the UTRN is especially useful.
- Check that you have the full 12-digit UTRN.
- Make sure the lead buyer’s details are available if the form needs them.
- Have the recipient’s bank account and sort code ready.
How to analyse it
Work through the form as two simple checks: can you identify the original transaction, and can the payment be sent to the right person?
- Identify the person making the claim.
- Check whether the lead buyer is someone else.
- Match the transaction details to the UTRN.
- State the refund amount you are claiming.
- Check the bank details for the payment recipient.
Example
Nia is completing a refund form after an earlier property purchase. She has her contact details, the original transaction details and its 12-digit UTRN. As another buyer was the lead buyer, she also has that person’s details. Finally, she enters the refund amount and the bank details for the person due to receive it.
Why this can be difficult in practice
Although the checklist is short, missing one detail can stop you from completing the form. As the source does not say how to work out the refund amount, do not treat the form itself as a calculation guide.
- A UTRN is not the same as a general property reference.
- The lead buyer may not be the person completing the form.
- The payment details must be for the person receiving the refund.
Key takeaways
- Keep the original transaction details to hand.
- You need the 12-digit UTRN.
- Prepare the refund amount and bank details before starting.
