MTD Quarterly Update Deadline Calculator

What you need to know about quarterly updates

• Quarterly updates are NOT tax returns – they’re simple summaries of income and expenses
• Deadline is 7th of the month following the quarter end – applies to both 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 must be recorded digitally
• Use compatible software – HMRC requires approved MTD-compatible software
• We wrote an original song about MTD and quarterly updates, it’s called “Four times a year” and is absolutely not AI-generated but rather written and recorded in an actual studio in London. It’s available on Apple Music, Spotify, and there’s a lyric video on YouTube – and it definitely helps remember the MTD deadlines.
