LTT penalty notice: when to pay and what to check
Read a Land Transaction Tax penalty notice as soon as it arrives. It should state the amount due, how to pay, and what to do if you disagree with WRA’s decision on the penalty.
Check the notice carefully. According to the official guidance, payment is due within 30 days after you receive the notice unless you appeal, and that period starts when it reaches you. The clock starts on receipt.
If you pay late, daily interest can be added.
What this rule is about
Land Transaction Tax, or LTT, is Wales’s tax on certain purchases of land and property, applying to the transactions covered by the tax. It is a self-assessed tax.
As LTT is self-assessed, the buyer must provide WRA with an accurate tax return. The buyer must also calculate the tax due on the purchase using their information. That responsibility rests with the buyer.
A penalty is distinct from the tax itself. If something goes wrong, such as a late return or late payment, WRA may charge a penalty in addition to the tax due.
A notice is WRA’s written decision that a penalty is due.
What the official source says
The Welsh Government page gives a brief but important warning: do not ignore a penalty notice. It says that the notice will explain the amount, the payment method, and what to do if you disagree with WRA’s decision.
- Check the penalty amount shown on the notice.
- Check the payment instructions on the notice.
- Read the section explaining what to do if you disagree.
- Pay within 30 days of receiving the notice, unless you appeal.
- Expect daily interest if payment is late.
What this means in practice
Delaying during the 30-day period can increase the bill. Because the source gives no interest rate, this page cannot calculate the additional cost that may build up when payment is late and interest is added daily. The rate is not stated.
However, it makes clear that interest is charged each day after payment becomes late.
You may think that an objection can wait. That may not be the case.
If you want to challenge the penalty, the notice should set out the action WRA expects you to take rather than leave the next step unclear. Read it closely.
- Keep the notice and record the day you received it.
- Compare the notice with your LTT return and payment records.
- Check whether you have already paid the amount shown.
- Use the notice’s instructions if you do not agree with the decision.
- Do not assume that a question or complaint counts as an appeal.
How to analyse it
Begin with the notice rather than relying on guesswork, and ask what WRA says you did wrong, whether that account is correct, and which records support or contradict it. Start there.
- Identify the type of penalty stated in the notice.
- Check the amount and the dates used by WRA.
- Find the relevant return, payment confirmation and messages.
- Check the date you received the notice.
- Read the notice for the steps to take if you disagree.
- Decide whether payment is due while any appeal is being made.
Example
Gareth receives an LTT penalty notice on 8 July. The notice states what he owes and how to pay. He checks his return and finds that WRA may have used incorrect information.
He should promptly use the challenge details in the notice. If he does not appeal, the official guidance says he must pay within 30 days of receiving the notice WRA sent him.
He should not delay. If the amount remains unpaid, daily interest may build up.
Why this can be difficult in practice
The notice might arrive long after the property purchase, by which time it can be difficult to find the papers.
Someone may accept that a return was late while still disputing either the penalty amount or the reason given for it, because those questions are not the same. They are separate issues.
- The supplied guidance does not set out the appeal process or its deadline.
- It does not give the daily interest rate.
- It does not explain every kind of LTT penalty.
- Payment deadlines for tax, a return, and a penalty notice are separate.
Key takeaways
- Read an LTT penalty notice as soon as you receive it.
- Unless you appeal, pay within 30 days of receiving the notice.
- Late payment can lead to daily interest.
- Use the notice to check how to dispute WRA’s decision.
