Making Tax Digital for Income Tax
When is my next MTD update due?
Every year, Making Tax Digital for Income Tax has four quarterly deadlines. Here they are for 2026/27, with a live countdown — and you can drop all of them into your calendar in one click.
The four quarterly deadlines, 2026/27
| Quarter covered | Update due by |
|---|
Your final declaration for 2026/27 — the bit that replaces your old Self Assessment return — is due 31 January 2028. Updates are cumulative, so a later quarter can correct an earlier one; you don't have to be perfect on day one.
Downloads a standard calendar file with a reminder a week before each date. Works with Google Calendar, Outlook and Apple Calendar. Nothing is sent anywhere.
What you actually send each quarter
- Cumulative totals of your business income and expenses, by category
- Submitted from software that connects to HMRC — a spreadsheet plus bridging software counts
- One update per source: self-employment and property are reported separately
- You can send any time from the end of the quarter up to the deadline
No fines for a late quarterly update in 2026/27
HMRC has confirmed a soft-landing: no penalty points for late quarterly updates during the 2026/27 tax year. From 2027/28 the points system starts — each missed quarterly update or return is one point, and four points triggers a £200 penalty. So this first year is the one to build the habit in, while mistakes are free.
