Making Tax Digital for Income Tax: What UK Sole Traders and Landlords Need to Know in 2026

Making Tax Digital (MTD) for Income Tax is one of the biggest changes to the UK tax system in recent years. From April 2026, many sole traders and landlords earning over the qualifying income threshold must keep digital records and submit quarterly updates to HMRC instead of relying solely on an annual Self Assessment tax return.

The new rules are designed to improve the accuracy of tax reporting and reduce errors. However, many business owners remain unsure about when they need to comply, what software they should use, and what happens if they miss a deadline.

To prepare for MTD, businesses should:

• Check whether they fall within the income threshold.
• Use HMRC-compatible accounting software.
• Keep digital records throughout the year.
• Submit quarterly updates on time.
• Continue filing the required end-of-year declaration.

Preparing early helps avoid unnecessary stress, missed deadlines, and potential penalties. It also gives businesses a clearer picture of their finances throughout the year, making cash flow management and tax planning much easier.

As HMRC continues expanding Making Tax Digital, adopting digital bookkeeping now is the best way to stay compliant and save time in the future.
