April 2026 MTD Rollout Explained: What Sole Traders Need to Know

What is the April 2026 MTD Deadline?

April 2026 marks the point at which Making Tax Digital for Income Tax Self Assessment (MTD ITSA) becomes mandatory for sole traders and landlords with qualifying income above £50,000 per year. From this date, you will be required to keep digital records and submit quarterly updates to HMRC using approved software, replacing the current annual Self Assessment return for this portion of your tax affairs.

The April 2026 deadline has been legislated and is not expected to change. It follows several years of delays and pilots, and HMRC is now focused on helping businesses prepare rather than postponing further.

Who is Affected from April 2026?

The April 2026 requirement applies to any UK sole trader or landlord whose qualifying income — the combined gross income from self-employment and property before expenses — exceeds £50,000 in the 2024/25 tax year. If you fall into this group, you must sign up for MTD for Income Tax and begin submitting quarterly updates from April 2026.

Partnerships, limited companies, and PAYE employees without self-employment income are not in scope for April 2026. However, HMRC has indicated that the scheme will be extended over time.

What Happens if I Miss the Deadline?

HMRC uses a penalty points system for MTD non-compliance. Each missed quarterly submission deadline earns you a penalty point. Once you reach a certain threshold of points — currently four for quarterly filers — a financial penalty of £200 is charged. Points can be erased after a period of full compliance.

Beyond quarterly submissions, failing to sign up at all could result in further sanctions. HMRC has stated it will take a supportive approach in the early months of mandatory MTD, but this will not last indefinitely.

What Do I Need to Do Before April 2026?

There are three main things you need to do before April 2026: choose MTD-compatible software, set up digital records, and formally sign up for MTD through your Government Gateway account. Leaving any of these steps to the last minute increases the risk of problems when the deadline arrives.

We recommend starting your software evaluation at least six months before the deadline, so you have time to test the software with your actual records, make adjustments to how you categorise income and expenses, and ensure your software connects successfully to HMRC's systems.

The April 2027 Extension: What Changes Next?

From April 2027, MTD for Income Tax will extend to sole traders and landlords with qualifying income between £30,001 and £50,000. This second phase means that a significantly larger group of self-employed people and landlords will need to comply within the following year. If your income falls in this band, it is worth getting familiar with MTD now — the software you choose and the habits you build will be the same regardless of which deadline applies to you.

HMRC has not yet confirmed when — or whether — MTD will be extended to those earning below £30,000. This group is currently out of scope, and no mandatory date has been announced.
