The WRA can cancel an agreed LTT payment deferral if it thinks a condition was broken, or information was false, misleading or withheld.
- The deferral is then treated as never having been requested.
- Interest can run from the day after the return filing date.
- Keep the agreement, later changes and proof of compliance.

When the WRA can cancel an LTT payment deferral
Where the Welsh Revenue Authority allows you to delay payment of land transaction tax, it can cancel that delay if you fail an agreed condition.
When the WRA cancels the delay, the original payment date is restored, and, because the request is treated as never made, interest may run from the day after the return filing date. LTT is Wales’s version of stamp duty.
What this rule is about
In limited cases, a deferral can let you delay part of an LTT payment where the WRA agrees to the delay and sets conditions for it. Those conditions matter. It can later agree to change those conditions or the expected end date.
This is not a small administrative point. If the WRA cancels the deferral, it treats the request as though you never made it.
What the official source says
The WRA guidance says it may undo a deferral if it believes you did not meet a condition in the original or changed agreement.
It may also do so if it believes information given with the original request, or a later request to change the delay, was false or misleading. The same applies where it believes information was held back. This matters.
- The condition may be one set in the original deferral agreement.
- It may be a condition changed under a later agreement.
- The issue may concern the original request for a delay.
- It may concern a later request to change that delay.
- The WRA must send you a notice when it takes this step.
- The law requires that notice to explain the result and its consequences.
- The WRA guidance says the notice will also give its reasons.
What this means in practice
When the deferral is treated as never made, the usual LTT payment rule applies again, so the payment is due under that rule rather than under the delayed arrangement. The delay no longer applies.
Interest therefore runs from the day after the filing date for the return, rather than from the date of the cancellation notice.
That can create a bill for interest over a long period. Because the source gives no interest rate, none should be assumed.
- Keep the WRA notice that agreed the delay.
- Read every condition in that notice carefully.
- Keep proof that you met payment or information conditions.
- Tell the WRA promptly if circumstances change.
- Keep copies of any request to change the agreement.
How to analyse it
Begin with the actual agreement, rather than with what you thought had been agreed, because the conditions and any later changes must be identified from the documents themselves. Check the documents. Then check the information sent to the WRA at each stage.
- What amount of LTT did the WRA agree to defer?
- Which conditions did the WRA set?
- Was any condition later changed or removed?
- What facts does the WRA say were wrong, missing or misleading?
- Did the alleged failure relate to the original request or a later change request?
- What does the cancellation notice say the consequences are?
- Does the notice explain why the WRA reached that view?
Example
Maya receives approval to delay part of her LTT payment. Her approval requires her to make a stated payment at a stated time. She misses it.
If the WRA thinks that she failed the condition requiring the stated payment at the stated time, it can treat her request for a deferral as never made. The delay disappears. Interest can then run from the day after the return filing date.
Why this can be difficult in practice
Several letters, forms and emails may contain the key facts, particularly where the original agreement was changed later and the relevant terms appear across different documents. Read them together. A changed agreement matters just as much as the first one. You may think a later conversation changed a condition, but the documents may say otherwise.
- A missed condition can affect interest from an earlier date.
- Giving incomplete facts can be as serious as giving wrong facts.
- A request to change an agreement is also part of the risk area.
- The supplied guidance gives no time limit for challenging the decision.
Key takeaways
- Meet every condition in the WRA’s deferral agreement.
- Keep full records of what you told the WRA.
- A cancelled deferral can lead to interest from the filing date.

- LTTA 2017 section 62 — requests to change a deferral agreement

Official guidance
The pages below are the Welsh Revenue Authority’s guidance. Guidance is not law. It sets out how the Welsh Revenue Authority reads the legislation, and it is not binding on you, on a tribunal or on a court. 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 WRA guidance says its notice should give the reasons for its decision. The supplied text of LTTA 2017 s.63(2) expressly requires the notice to state the result and its consequences, but does not expressly mention reasons.
- No currency notice was available in the mounted statutory materials, so the current wording and procedure should be checked before relying on this page for a later transaction or dispute.
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 WRA’s original deferral notice and every condition attached to it
- Any later request to vary the agreement and the WRA’s response
- Proof of payments, dates and correspondence with the WRA
- The notice cancelling the deferral and its stated consequences
