How Quarterly Reporting Works

The phrase "quarterly reporting" sounds heavy, but a quarterly update under Making Tax Digital is much simpler than a tax return. It's a short, running summary of your business income and expenses — sent to HMRC through compatible software.

What a quarterly update is

Each quarter you send HMRC your cumulative totals (year-to-date) of income and expenses, summarised by category. You're not calculating your final tax bill, and you're not claiming reliefs yet — you're just keeping HMRC up to date. Because the figures are cumulative, each update simply builds on the last.

The yearly rhythm

Four quarterly updates across the year (due 7 Aug, 7 Nov, 7 Feb and 7 May).
A final declaration after the tax year ends, where you confirm your figures, add anything else (like other income or reliefs), and finalise your tax. This replaces the old Self Assessment return and is due by 31 January.

What you need in place

Digital records of each income and expense item, kept as you go.
MTD-compatible software (or a spreadsheet plus bridging software) to send the figures.
A simple habit of updating your records — little and often beats a quarterly panic.

The good news

Quarterly updates are summaries, not mini tax returns.
The figures are cumulative, so the maths carries forward automatically.
With records kept up to date, each submission should take minutes.

The biggest difference from the old system is rhythm: instead of one big annual effort, you do a little each quarter. Most people find that, once set up, it actually makes their finances less stressful — because they always know where they stand.
