Making Tax Digital 2026: The Essential Guide for UK Small Businesses and Landlords

April 2026 is set to be a landmark moment for UK taxpayers. For the first time in decades, the familiar once-a-year Self Assessment process will be replaced with a fully digital reporting system. If you’re a sole trader or landlord earning over £50,000, this change affects you directly.

In this guide, we break down Making Tax Digital for Income Tax (MTD for ITSA), what it means for your business, how to comply, and the best software to help you make the transition smoothly.

Whether you’re new to digital accounting or looking to streamline your processes, this guide will help you prepare, stay compliant, and even take advantage of the efficiencies MTD offers.

What Is Making Tax Digital (MTD) for Income Tax?

MTD for Income Tax Self Assessment (ITSA) is HMRC’s push towards a fully digital tax system. Its goal? To make tax reporting more accurate, timely, and less stressful.

Under the new system:

• Paper records are no longer enough, you must keep digital financial records.
• You will submit four quarterly updates instead of one annual tax return.
• A final declaration is filed by 31 January each year to reconcile your income, expenses, and reliefs.

This system not only reduces errors but also gives both HMRC and businesses better visibility of tax liabilities throughout the year.

Who Must Comply — And When?

MTD is being introduced gradually based on your gross qualifying income (trading + rental income before expenses). Here’s the phased rollout:

Phase	Start Date	Income Threshold	Based on Tax Year
Phase 1	6 April 2026	Over £50,000	2024/25
Phase 2	6 April 2027	Over £30,000	2025/26
Phase 3	6 April 2028	Over £20,000	2026/27

Key point: If your 2024/25 tax return shows income above £50,000, you must enter MTD from April 2026.

Currently not included:

• Limited companies
• Most partnerships

What Changes Under MTD?

1.) Digital Record-Keeping

Paper records are no longer compliant. You’ll need to keep your financial records in a digital format, either using HMRC-approved software or digitally linked spreadsheets.

2.) Quarterly Submissions

Instead of filing a single annual return, MTD requires you to submit updates every three months. This spreads your workload and keeps HMRC informed in real time.

3.) Final Declaration

A final declaration is still required by 31 January following the tax year, confirming your income, expenses, and reliefs.

Important: Tax payment dates (31 January and 31 July) remain unchanged.

How to Prepare for MTD in 2026

For businesses likely to exceed the £50,000 threshold, preparation is key. Steps to take now include:

• Review your 2024/25 income
• Move away from paper records
• Trial MTD-compatible software
• Speak with your accountant
• Consider running a parallel digital system before April 2026

Early adoption reduces risks, spreads workload, and gives you peace of mind when the new system kicks in.
