Deadlines are 7 August, 7 November, 7 February and 7 May; the final declaration is due by 31 January, two calendar years after the tax year starts (for example 31 January 2028 for 2026-27). The four quarterly updates must be sent before the final declaration. Late quarterly updates carry no penalty points in 2026-27; points start from 2027-28.

Whether people starting in April 2027 get any further penalty-points grace is not confirmed. Dates for earlier periods may already have passed.
