DST63900 | Determination Superseded by Self-Assessment
From HM Revenue & Customs · Digital Services Tax Manual
If, after an HMRC determination has been made, a DST return is delivered for the accounting period, the self-assessment included in the return supersedes the determination provided the return is delivered no later than:
3 years after the day on which the power to make the determination first became exercisable, or
twelve months after the date of the Revenue Determination.
The following example with different scenarios demonstrates how and when a Revenue Determination is superseded by a Self-Assessment return:
Example
Group A makes up its accounts to 31 December annually.
The filing date for the return is 31 December 2022.
1 January 2023 is the day which the power to make the determination first became exercisable
HMRC have reasonable grounds for believing the responsible member is under a duty to deliver a DST return for the accounting period.
Scenario 1
HMRC make a Revenue Determination for that period on 10 July 2023
The responsible member delivers a return in February 2024
The Self-Assessment supersedes the Revenue Determination;
as it is within 12 months after the date of the Revenue Determination
it is also within 3 years after the day on which the power to make the determination first became exercisable
Scenario 2
HMRC make a Revenue Determination for that period on 10 July 2023
The responsible member delivers a return in October 2024
The Self-Assessment supersedes the Revenue Determination;
as it is within 3 years after the day on which the power to make the determination first became exercisable
even though it is more than 12 months after the date of the Revenue Determination
Scenario 3
HMRC make a Revenue Determination for that period on 10 March 2025
The responsible member delivers a return in February 2026
The Self-Assessment supersedes the Revenue Determination;
as it is within 12 months after the date of the Revenue Determination
even though it is more than 3 years after the day on which the power to make the determination first became exercisable
Scenario 4
HMRC make a Revenue Determination for that period on 10 March 2025
However, the responsible member delivers a return in April 2026
The Self-Assessment does not supersede the Revenue Determination;
as it is more than 12 months after the date of the Revenue Determination
it is also more than 3 years after the day on which the power to make the determination first became exercisable.
