This archive guide was checked and updated on 16 October 2026. Its original publication date is retained, but the timetable below reflects HMRC's guidance for the 2026–27 tax year.
Put the right dates in the diary
For the first tax year beginning in April 2026, quarterly updates are due by 7 August 2026, 7 November 2026, 7 February 2027 and 7 May 2027. The old article's deadlines on the fifth should not be used.
The periods covered depend on whether the business uses standard or calendar update periods. Check the accounting period in the software rather than assuming that the submission deadline and the end of a quarter are the same day.
The annual return still matters
Quarterly updates are not a replacement for completing the year-end tax return. HMRC's timetable requires the 2026–27 return to be prepared and submitted using compatible software by 31 January 2028, with adjustments, other income and relevant reliefs addressed.
Keep the submission calendar separate from payment reminders. Completing an update is not evidence that the tax bill has been paid.
If an update has been missed
HMRC states that there are no penalties for missing quarterly update deadlines for 2026–27. This is a limited first-year position, not permission to abandon records or ignore other tax obligations.
Bring missing digital records up to date and check the position with HMRC or the adviser handling the return. Retain submission acknowledgements and investigate rejected updates promptly. A calendar reminder helps, but the software's confirmation is the evidence that an update reached HMRC.
