MTD quarterly deadlines

Last updated: 2 May 2026

If you are in scope for MTD for Income Tax, you have four quarterly updates each tax year, plus a final declaration that replaces your Self Assessment return. Standard quarter dates use HMRC's default tax-year calendar; if you have elected calendar quarters, your dates differ by a few days.

Each link below is a small .ics file. Open it on a Mac, iPhone, Android, Windows, or in your webmail to add the deadline to Apple Calendar, Google Calendar, Outlook, or Fastmail. Nothing is sent to this site, and no email signup is needed.

A note on quarter cycles

HMRC's default cycle uses tax-year quarters (6 April to 5 July, etc.) with submissions due one month and two days after each quarter end. You can also elect calendar-month quarters, which align to the end of the calendar month and shift each due date by a few days. Both options produce the same final declaration deadline of 31 January following the tax year.
