HMRC is sending letters re MTD for ITSA

Anna Stubbs • March 18, 2025

You may find a brown letter from HM Revenue & Customs (HMRC) dropping onto your doormat soon, with details of the soon-to-be-mandatory MTD for ITSA.

But what is ‘MTD for ITSA’ and why do you need to know about it?

Your two-minute guide to MTD for ITSA


Making Tax Digital for Income Tax & Self Assessment (or MTD for ITSA) is part of HMRC’s ongoing initiative to convert the UK tax return process over to a digital system.


If you’re a sole trader or landlord, you’ll soon need to:

  • Keep digital records of all your income and expenses.
  • Use MTD-compatible software for your bookkeeping and accounting.
  • Submit regular quarterly digital reports to HMRC.
  • Send a full digital tax return at the end of the tax year.


Landlords and sole traders who fall into the following categories will soon find it’s mandatory to use the MTD for ITSA system.

  • from April 2026, for those with qualifying income over £50,000.
  • from April 2027, for those with qualifying income over £30,000.


A brown envelope with your MTD ITSA reminder


From April 2025, HMRC will be starting a campaign to raise awareness of the looming deadline to become compliant with the MTD for ITSA rules.


This will be kickstarted with an official HMRC brown envelope being sent to sole traders and landlords with a total self-employment and/or property income of over £50,000.


You’ll receive a letter if your 2023 to 2024 self assessment tax return shows your total income (turnover, not profit) as being either over, or close, to £50,000.


Don’t panic! We can help you get ready for MTD



An official letter from HMRC can sometimes be cause for concern. But there’s no need to worry unduly about MTD for ITSA. The mandatory deadline for compliance is still a year away, so there’s plenty of time to update your systems and get yourself compliant.


Come and talk to the team and we’ll explain the implications of MTD for ITSA, the need for digital records and how to get compatible cloud accounting software up and running.

Scenario planning is the process of using your existing business data to project and forecast the future path of your finances, sales and growth as a small business. By running various scenarios, you get an overview of the potential opportunities, threats and financial pitfalls that lie ahead, giving you time to plan for these eventualities.

Setting goals for you and your business for the new financial year

By Anna Stubbs • March 18, 2026
The new financial year is a new beginning. As a business owner this a great time for you to reflect on where you are at and think about your business goals for the financial year ahead. Setting goals is an essential part of personal and professional growth. These could be lofty goals, or even setting out a plan to achieve some more mundane (but equally important) projects. Whether that is getting paid faster, reassessing expenses or bigger things like automation of processes and new markets. You may be looking to expand your business or create more time for yourself.
