Land transaction tax: late review requests need a reasonable excuse and no unreasonable delay

Land transaction tax: late review requests need a reasonable excuse and no unreasonable delay
Missing the deadline to ask the WRA to review a tax decision does not always end the matter. The WRA may still look at it if you had a reasonable excuse and acted without unreasonable delay once that excuse ended.
What this rule is about
A review is a way of asking the Welsh Revenue Authority, or WRA, to look again at one of its decisions. This is relevant when you think a land transaction tax decision is wrong but sent your request late.
Being late is not enough on its own. Explain why it happened. Act promptly when you can.
That second part matters. A good reason at first may not explain a long wait later.
What the official source says
The Welsh Government guidance says the WRA will consider a late request only where it is satisfied about two things. These are separate conditions, so meeting one does not automatically meet the other.
- You had a reasonable excuse for not sending the review request within the time limit.
- You sent the request without unreasonable delay after that excuse stopped applying.
- The WRA will write to tell the person asking whether it will carry out the review.
If the WRA refuses to review the decision, seek permission from the tribunal. Your application must explain why the review request was late.
The tribunal also considers timing. You must apply without unreasonable delay.
- There must have been a reasonable excuse for the late review request.
- The request to the WRA must have followed without unreasonable delay after the excuse ended.
- The application to the tribunal must also have been made without unreasonable delay.
If the tribunal accepts the application and tells the WRA to review the decision, the WRA must carry out that review.
What this means in practice
Do not assume that a missed deadline makes your position hopeless. Equally, do not assume that explaining the first delay is enough. The timeline after the problem ends is part of the test.
For example, an illness may explain why you could not deal with the request at first. It may not explain a further delay after you were able to act.
- Write down the date the deadline expired.
- Set out what stopped you from sending the request on time.
- Identify when that problem ended or became manageable.
- Send the request as soon as you can after that point.
- Keep records that support the dates in your explanation.
The official source does not set a fixed number of days that will always be acceptable. It uses the phrase “unreasonable delay”, so the facts and the sequence of events matter.
How to analyse it
Start with dates, not broad claims. A short and clear timeline will usually show the real issue.
- What decision did you want the WRA to review?
- When did the normal period for asking for that review end?
- Why could you not send the request in time?
- Why was that reason a reasonable excuse in your circumstances?
- When did the excuse stop applying?
- What did you do between that date and the date you sent the request?
- If the WRA refused, when did you apply to the tribunal?
Answer each question with dates and documents where possible. A vague account can make it hard to see whether there was avoidable delay.
Example
Imagine that Mari misses the deadline for asking the WRA to review a decision. She explains that a serious problem stopped her dealing with it. Once that problem ends, she sends her request promptly and includes a timeline. The WRA will consider whether those facts show both a reasonable excuse and no unreasonable delay.
Now change one fact. Mari waits for a substantial period after the problem has ended, without explaining why. Her original reason may still have been genuine, but the later wait may cause difficulty.
Why this can be difficult in practice
The key words are not defined in the supplied guidance. “Reasonable excuse” and “unreasonable delay” need a judgment about what happened, when it happened, and what you could realistically have done.
- People may explain why they first missed the deadline but not the time that followed.
- A reason can stop applying before all practical problems have disappeared.
- Waiting after a WRA refusal can create a separate issue for a tribunal application.
- The WRA guidance describes its approach; the current legislation should also be checked for the rules in force at the relevant time.
Three periods may need explanation: the missed deadline, the time before the late request, and, if needed, the time before the tribunal application.
Key takeaways
- A late request may still be considered.
- You need a reasonable excuse and prompt action afterwards.
- If the WRA refuses, a tribunal application has its own delay test.
