MTD ITSA deadlines explained: when you need to submit and what to file

Making Tax Digital (MTD) is finally becoming a reality for sole traders and landlords.

If you earn more than £50,000 from self-employment or property, you’ll need to start reporting to HMRC every quarter instead of just doing a yearly tax return. The new regime starts from April 2026.

If you earn between £30,000 and £50,000, you will join the system from April 2027.

For a full breakdown of what the MTD rules mean in practice, see our guide to Making Tax Digital for the self-employed.

Getting prepared for MTD isn’t something to overly panic about, but it’s also something you shouldn’t ignore.

You’ll need to use digital accounting software, keep accurate records, and get used to the new reporting method.

We recently reported how most self-employed people still aren’t ready for MTD. But even if the new rules don’t apply to you now, it’s worth getting used to MTD while there is no immediate pressure.

Will MTD ITSA apply to you?

You’ll fall under MTD ITSA if your total gross income from self-employment and/or property is over £50,000 in a tax year. This includes:

  • Sole trader income
  • UK or overseas rental income
  • Furnished holiday lettings

If your combined income is between £30,000 and £50,000, you’ll join the scheme a year later, from April 2027.

If your gross income is under £30,000, MTD ITSA doesn’t yet apply to you.

However, the government has confirmed that it plans to extend the scheme to those earning over £20,000 from April 2028 and to bring more taxpayers into the system over time. You can read the full guidance on GOV.UK.

What information do you have to submit?

Instead of filing one Self Assessment return by the end of January each year, you’ll be reporting throughout the year using MTD-approved software. You’ll need to submit:

  • Quarterly updates showing your income and expenses
  • End of period statement (EOPS) – to finalise your year’s figures
  • Final declaration – this replaces the current Self Assessment return

Each type of income (trading and property) needs to be reported separately. So if you’re a sole trader and a landlord, you’ll have to keep two sets of digital records and file two sets of reports.

What are the quarterly deadlines?

Under the default system, quarterly updates must be submitted cumulatively, covering all of your business activity from the start of the tax year up to each quarter’s end.

These are the deadlines:

If you prefer, you can apply to use calendar-quarter reporting, which uses standard quarters (e.g., 1 April to 30 June). The same 7th-of-the-month deadlines still apply.

How to prepare for MTD ITSA

If you’re in the first wave of sole traders or landlords to join MTD, don’t wait until April 2026 to act.

You’ll need to have everything in place from the start of the 2026/27 tax year – and ideally beforehand.

Here’s what you can do now:

  • Choose MTD-compliant software. Tools like Xero, FreeAgent, and QuickBooks are already set up to handle MTD.
  • Start digital recordkeeping early. If you’re not joining MTD right away, use the coming year as a trial run. Keep receipts, mileage, income, and expenses in software rather than on paper or in spreadsheets.
  • Improve your bookkeeping habits. If you only update your records once a year, that will have to change. Under the new MTD rules, you will need to keep your records updated regularly.
  • Talk to your accountant. If you use one, find out how they’ll manage your MTD submissions and whether their fees will change. If you don’t use an accountant, consider whether now’s the time to get one.
  • Plan for multiple income sources. If you’re both a landlord and a trader, you’ll need to keep records and file separately for each stream.

What if you don’t comply with MTD?

HMRC is introducing a new points-based penalty system for MTD ITSA. If you miss a deadline, you get a penalty point. Once you reach a certain number of points, you’ll be fined.

These points reset after a period of good behaviour, but it’s better not to get them in the first place.

It’s worth noting that HMRC has confirmed a soft landing for the first year: penalty points will not be issued for late quarterly updates during 2026/27, giving new MTD users time to adjust.

However, financial penalties for late Final Declarations and inaccuracies still apply from day one.

Late submissions, missing records, or filing outside the software could all result in penalties.

Get ready in advance

The most effective way to prepare for Making Tax Digital is to put the right systems in place before you are required to comply.

If you are already using cloud accounting software with a live bank feed, much of the groundwork is done.

The main adjustment is to your routine: keeping your records up to date, reconciling bank transactions within your accounting software, and meeting the quarterly deadlines.

The earlier you prepare, whether for April 2026 or a later entry point, the less disruption you are likely to face.
