How quarterly updates work
HMRC requires quarterly income and expense summaries. Here is how they work in practice. Direct submission to HMRC is not currently available.
Quarterly updates are a cornerstone of Making Tax Digital.
They are Cumulative
A common misconception is that each update covers only three months of data in isolation. In reality, each update is cumulative from 6 April to the end of the relevant quarter.
Deadlines
- Quarter 1 (6 Apr – 5 Jul): Deadline 7 August
- Quarter 2 (6 Apr – 5 Oct): Deadline 7 November
- Quarter 3 (6 Apr – 5 Jan): Deadline 7 February
- Quarter 4 (6 Apr – 5 Apr): Deadline 7 May
