How to file and pay Land Transaction Tax in Wales
If you buy property or land in Wales, you may need to file a Land Transaction Tax return and pay any tax within 30 days. LTT is the Welsh property tax often called stamp duty. Missing the deadline can lead to interest and penalties.
What this rule is about
Filing tells WRA about the purchase. WRA is the Welsh Revenue Authority. Payment is a separate step, but it has the same deadline.
The date that matters is usually completion. That is normally the day you get the keys or the sale legally finishes. In some situations, another date can count instead. This is called the effective date.
What the official source says
WRA says you must send an LTT return and pay any LTT due within 30 days, starting on the day after completion or another effective date. A return can still be needed even when you owe no LTT.
- You normally need a return for a notifiable land transaction.
- No tax to pay does not, by itself, mean no return is needed.
- A specific statutory exception may mean that no return is required.
- Any tax due must be paid by the return deadline.
- From 3 July 2023, solicitors and conveyancers can file LTT returns online.
- If you have no solicitor or conveyancer, WRA says to contact it for a paper return.
A solicitor or conveyancer can handle this. The return must still be correct and complete. The law makes the buyer responsible for the return and the tax.
What this means in practice
If a solicitor or conveyancer is handling your purchase, you can ask them to submit the online return and make the payment. They will usually add the tax to the money you send them before completion.
Without one, contact WRA for a paper return. Do not wait until the deadline is close. WRA needs enough information to send the right forms.
- Tell WRA if there are more than two buyers.
- Tell WRA if there are more than two sellers.
- Tell WRA if the purchase includes more than one piece of land.
- Give WRA your preferred language when you contact it.
- Make sure both filing and payment are dealt with by the deadline.
Filing and paying are linked because the same deadline applies, but filing does not remove the need to pay any tax due. Neither step replaces the other. Sending a return without paying tax due can still leave a problem.
How to analyse it
Start with the date, then work forward. Do not assume that a nil tax result means you can ignore the return.
- What was the completion date?
- Could another date count as the effective date under the LTT rules?
- Is the purchase a transaction that must be reported?
- Does a statutory exception from filing apply?
- Is any LTT due on the information in the return?
- Will a solicitor or conveyancer file online for you?
- If not, have you contacted WRA early enough for a paper return?
Count 30 days from the day after the effective date, which is usually completion but can be another date in some situations. That is the usual rule. The return and any payment must reach WRA by the end of that period.
Example
Because Rhodri completes his purchase on 1 March, the 30-day period starts on 2 March, making 31 March the due date for his return and any LTT payment. That is his deadline. He does not use a conveyancer, so he contacts WRA for a paper return. If the purchase includes three buyers, he tells WRA that when asking for the forms.
Why this can be difficult in practice
Many people focus only on whether tax is due. That is not the full question. The separate question is whether the transaction needs a return.
Completion is normally the key date, but it is not always the effective date. If your arrangement is unusual, do not simply count from the moving day without checking the date that applies to the transaction.
- A zero tax amount may still require a return.
- A filing exception depends on the legal details of the purchase.
- Several buyers, sellers or plots may affect which paper forms WRA sends.
- Late filing and late payment can result in penalties and interest, as WRA says.
Key takeaways
- File and pay within 30 days of the day after the effective date.
- A return may be needed even if no LTT is due.
- Without a conveyancer, contact WRA for a paper return.

- The completion date and any fact suggesting a different effective date.
- Whether the transaction falls within a statutory exception from filing.
- Whether a solicitor or conveyancer is acting for the buyer.
- The number of buyers, sellers and separate pieces of land for a paper return.
