MTD for Income Tax: Quarterly Deadline Calculator

Get your exact Making Tax Digital deadlines — four quarterly updates, the final declaration and your tax payment dates — and add them all to your calendar. No personal figures needed.

Quarterly period type

Payments on account only apply if last year's Self Assessment bill was over £1,000 and less than 80% was collected at source (e.g. via PAYE). In your first mandated year there's no prior-year payment on account carried in — just the 31 January balancing payment.

2026/27 soft landing: no late-submission penalty points on the four quarterly updates this year — but the final declaration can still be penalised, and late-payment penalties and interest still apply.

How MTD deadlines work

Once you're mandated, you send four quarterly updates a year — cumulative year-to-date totals — due 7 August, 7 November, 7 February and 7 May. These dates are the same whether you keep standard (tax-year) or calendar quarters; only the period each update covers changes.

After the year you complete a final declaration by 31 January, which replaces your Self Assessment return. Sending quarterly updates doesn't change when you pay — your balancing payment and payments on account stay on the usual 31 January / 31 July dates.
