Build your quarterly schedule

Choose a tax year and update-period type to see the quarter dates and deadlines clearly.

Tax year

Update-period type

Standard update periods

These align with the tax year from 6 April to 5 April.

Calendar update periods

These end on the last day of the month.

Quarter 1

Update period:

6 April 2026 to 5 July 2026

Quarter 2

Update period:

6 April 2026 to 5 October 2026

Quarter 3

Update period:

6 April 2026 to 5 January 2027

Quarter 4

Update period:

6 April 2026 to 5 April 2027

These align with the tax year from 6 April to 5 April and will be the clearest route for many users.

These can be simpler for users whose accounting period ends on 31 March, as long as their software supports that option.

After understanding the schedule, the next useful area will be digital record-keeping and software support.
