Land Transaction Tax: when exceptional circumstances may allow extra time to pay
Land Transaction Tax: when exceptional circumstances may allow extra time to pay
If you cannot file your Land Transaction Tax return or pay LTT on time, tell the Welsh Revenue Authority (WRA) as soon as you can. Do this before the due date. In exceptional cases, WRA may consider giving you more time to pay.
What this rule is about
When you buy land or property in Wales, LTT may apply, and the law can require you to file a return and pay the tax by the filing date. This guidance is for people whose circumstances make that difficult.
What the official source says
Although the WRA page is guidance rather than the law itself, it says that you should contact WRA promptly if your circumstances mean you cannot file or pay on time. Contact WRA early.
- Tell WRA as soon as possible.
- Make contact before the return is due.
- Make contact before the tax payment is due.
- Explain that your circumstances prevent you filing or paying on time.
- WRA might consider extra time to pay where the difficulty is exceptional.
What this means in practice
If a problem may stop you from filing or paying by the deadline, raise it before that date, because a request for help does not itself amount to an agreed change to a deadline. Do not wait.
- Check whether the problem affects filing, payment, or both.
- Contact WRA before the relevant due date.
- Explain the circumstances causing the problem.
- Do not assume that contacting WRA extends the filing deadline.
- Do not assume that extra time to pay has been granted.
How to analyse it
Begin with the immediate problem, then distinguish between what the official page says and what it does not say. Keep those points separate.
- When is your LTT return due?
- When is the tax payment due?
- Can you tell WRA before either date?
- Are your payment difficulties exceptional?
- Has WRA confirmed any payment arrangement?
Example
Rhys knows that his LTT payment is due on Friday, but a sudden problem means he cannot pay it then. He contacts WRA on Thursday and explains the position. The guidance says WRA may consider more time if his difficulty is exceptional. It does not mean Friday’s payment date has already changed.
Why this can be difficult in practice
The word “exceptional” matters because the source does not explain which circumstances meet that description, how long extra time may last, or what WRA will ask for. It also does not promise extra time to file a return.
- Not every payment problem will necessarily be exceptional.
- Help with payment is not stated to be help with filing.
- The details of any arrangement need confirmation from WRA.
Key takeaways
- Tell WRA before the return or payment is due.
- Extra time to pay is something WRA may consider.
- Do not treat contact with WRA as an automatic extension.

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

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 source does not define what counts as exceptional difficulties.
- The source does not state how much extra payment time WRA may allow or any conditions it may set.
- The source does not explain what help, if any, is available for a late LTT return.
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.
- The circumstances that mean you cannot file or pay on time.
- The date on which the return or payment is due.
- Any response or arrangement confirmed by WRA.
