How long does WRA have to issue a Land Transaction Tax assessment?
WRA will usually have four years to make a Land Transaction Tax assessment. But that period can be six years, 20 years, or measured differently in some cases. The date that starts the clock matters, and it may not be the date you expected.
What this rule is about
If WRA considers that too little tax was paid, or that a return was wrong, it can issue a formal assessment saying more tax is due. It is a formal notice.
There is a time limit because an old tax return should not stay open forever. Yet the limit is longer where WRA believes carelessness or deliberate action caused the problem.
What matters first: when did the clock start? Not every case begins on the same date.
What the official source says
According to WRA’s official technical guidance, the usual limit is four years after the relevant date, which in most cases is the filing date for the tax return. That is the usual rule.
- If the return was filed late, the relevant date is the day it was actually filed.
- If no return was filed, it is the date by which WRA believes it should have been filed.
- If WRA believes carelessness caused the position, the limit can be six years after the relevant date.
- If WRA believes deliberate conduct caused it, the limit can be 20 years after that date.
- The conduct may be by you, someone acting for you, or another partner in the same partnership.
- Wrong repayments: assessment within 12 months.
The source also sets separate rules for a person who has died. WRA must make the assessment on their personal representatives within four years of death. It cannot relate to a relevant date more than six years before the death.
What this means in practice
Do not assume that a transaction completed more than four years ago is outside WRA’s reach. A late return can move the starting point. So can an allegation that carelessness or deliberate conduct caused the mistake.
The notice matters straight away. WRA’s notice starts the 30-day payment period. That amount can include tax, penalties and interest.
- Keep the return and proof of when it was filed.
- Keep WRA letters, repayment records and payment confirmations.
- Check whether WRA has used the right relevant date.
- Read any allegation of carelessness or deliberate conduct closely.
- Check the notice issue date before working out the 30-day payment period.
You might think an assessment is final because it has arrived. It is not necessarily so. The source says that a person who says WRA was out of time must raise that point through a notice of review or an appeal against the assessment.
How to analyse it
Start with the ordinary four-year rule. Then test whether one of the different starting dates or longer periods changes the result. Do not begin by counting from the purchase date unless that is also the relevant date.
- Identify the return connected with the assessment.
- Find its filing date.
- Where it was filed late, record the actual filing date.
- Where no return was filed, identify when WRA says it should have been filed.
- Ask whether WRA alleges carelessness or deliberate conduct.
- If there was a repayment, identify the day it was paid.
- If the person has died, check both dates in the special death rule.
- Compare those dates with the assessment notice date.
- If you say the limit had ended, raise that ground in a review or appeal.
This is the part people can miss: the assessment notice date and the date you receive it are not described as the same thing in the official source. Keep the envelope, email and notice itself, but focus first on the issue date shown on the notice.
Example
Imagine Priya’s return was due on 30 June 2024, but she filed it on 15 August 2024. Under the official source, the relevant date is 15 August because the return was late. On the usual rule, the four-year period is measured from that later date, not from 30 June.
Now change the facts. WRA repays tax to Priya and later believes the repayment was wrong. Under the separate rule, the source gives WRA 12 months, starting on the day it made that repayment, to issue an assessment where it later believes Priya’s repayment was wrong. It is a separate rule.
Why this can be difficult in practice
Counting years is rarely the hard part. Working out which clock applies is harder. A missing return, a late filing, a repayment, or a claim that somebody acted carelessly can each change the answer because each may alter either the starting date or the period WRA can use. The right clock matters.
The words “careless” and “deliberate” also matter a great deal. They lead to very different time periods. The supplied source says these depend on what WRA believes, but it does not set out the detailed tests for either term.
- A completion date may not be the date that starts the time limit.
- A late-filed return can create a later relevant date.
- Missing records can make it harder to challenge WRA’s dates.
- A partnership case may involve another partner’s actions.
- A 30-day payment period can run while a time-limit challenge is being considered.
Key takeaways
- WRA usually has four years from the relevant date to assess.
- Carelessness and deliberate conduct can extend that to six or 20 years.
- Check the relevant date, the notice date and any repayment date carefully.
