What a quarterly update actually is

A quarterly update is a running summary of your income and expenses for that period, not a tax bill, and not the same as your Self Assessment return. Read what Making Tax Digital for Income Tax actually is for the full picture.

What happens after the four quarters

At the end of the tax year, you’ll still need to confirm your final figures, similar to today’s Self Assessment process. That part of MTD isn’t changing yet.

Common questions

Are the deadlines the same for everyone?

Most people use HMRC's 'standard' quarters shown below. Some businesses can elect calendar-quarter dates instead. Check with HMRC if you're unsure which applies to you.

What happens if a deadline falls on a weekend?

HMRC's deadlines are calendar dates, not adjusted for weekends, so check the actual date rather than assuming it moves to the next working day.
