Every Making Tax Digital deadline for landlords

Under Making Tax Digital you have a handful of dates each year: four quarterly updates and one year-end tax return. Each quarterly update is due about five weeks after its period ends.

The four quarterly updates (standard periods)

• Quarter 1 (6 April – 5 July): due 7 August
• Quarter 2 (6 July – 5 October): due 7 November
• Quarter 3 (6 October – 5 January): due 7 February
• Quarter 4 (6 January – 5 April): due 7 May

Each update is cumulative: you send the running year-to-date total, not just that quarter’s figures. Spot a mistake later? You simply resend the corrected total — no separate amendment.

The calendar-quarter option

If you’d rather your quarters line up with calendar months, you can elect “calendar update periods” (1 April – 30 June, and so on). The deadlines are the same. You choose this once, before your first update.

The tax return

After the tax year ends on 5 April, you confirm everything is complete and correct in a year-end tax return (HMRC previously called this the final declaration). It is due by 31 January the following year — the same date Self Assessment has always used — and your tax is also payable by 31 January.

What happens if you’re late

Missing an update doesn’t trigger an instant fine. HMRC uses points: you get a point each time you miss a deadline, and at four points you get a £200 penalty. Points expire if you stay compliant. It’s forgiving of the odd slip, but it pays to keep on top of them — which is exactly what Quarterwise’s reminders are for.
