Most people choose tax year quarters, but you can pick what suits your business

What you need to know about quarterly updates

  • Quarterly updates are NOT tax returns – they’re basic summaries of income and expenses
  • Deadline is 7th of the month following the quarter end – this applies to both the tax year and calendar quarters
  • You still file an annual return – due 31 January following the tax year
  • First-year grace period – no penalty points for late quarterly updates in your first MTD year
  • Keep digital records – all income and expenses have to be recorded digitally
  • Use compatible software – HMRC needs you to use approved MTD-compatible software
  • We wrote an original song about MTD and quarterly updates, it’s called “Four Times a Year” and no, it’s not AI. It’s a proper pop song, written and recorded in London. It’s available on Apple Music, Spotify, and there’s a lyric video on YouTube – and it definitely helps you remember the MTD deadlines.
