From 6 April 2026
Users with qualifying income over £50,000 in the 2024 to 2025 tax year are the first mandatory phase, so this is the earliest main start point most users will be checking against.
Guide
Who needs to use MTD for Income Tax?
Use this guide to understand the phased rollout, which groups are most likely to be brought into MTD first, and why qualifying income is the practical starting point for checking scope.
Quick answer
The answer depends on qualifying income, timing, and whether the user has self-employment or property income
The big mistake is assuming scope is the same for everyone. In practice, users need to think about the rollout phase, the threshold, and the type of income involved before treating MTD as an immediate requirement.
Why this guide matters
Many users ask the right question too broadly and get the wrong answer
The more useful question is not simply “Do I need MTD?” but “When am I likely to need it, and what does that depend on?” That is the real purpose of this page.
Rollout phases
The main dates and thresholds users usually need first
The phased rollout is one of the most important starting points, because it explains why two users can both have heard about MTD but still not face the same immediate timetable.
From 6 April 2027
Users with qualifying income over £30,000 in the 2025 to 2026 tax year are the next phase, which is why many people need to think about income bands and timing rather than asking only whether MTD exists at all.
From 6 April 2028
Users with qualifying income over £20,000 in the 2026 to 2027 tax year are part of the later rollout stage, so this becomes the next major expansion point in the current path.
Who this mainly affects
The core groups are sole traders and landlords with qualifying income from self-employment, property, or both. That is why this guide focuses on scope and timing rather than general tax questions.
Understanding scope
This is a scope-and-timing question, not only a headline announcement
Users often hear the broad policy first and the detail later. This section is there to make the detail clearer before anyone relies on a simple threshold headline alone.
Not everyone starts at the same time
A common misunderstanding is assuming that all self-employed users and landlords move into MTD at once. In practice, the start date depends on qualifying income and the phase you fall into.
Qualifying income is the key test
The broad headline is about the threshold and the phase date, but the threshold question still depends on qualifying income rather than the looser everyday way people often talk about profit or tax position.
Self-employment and property both matter
Some users only need to think about one income source. Others may need to consider self-employment income and property income together before reaching a sensible conclusion about likely scope.
Worked plain-English examples
Three practical ways users may need to think about scope
These are not substitute determinations. They are there to show why a proper scope check usually needs more than one headline fact.
Example 1: a sole trader above the first threshold
If a user’s qualifying income is above the first phase threshold, the practical next question is not whether MTD exists, but how soon they need to prepare for digital records, software, and quarterly reporting rhythm.
Example 2: a landlord below one phase but above the next
A landlord may not fall into the earliest phase but may still be brought in later. That is why the guide is about timing and scope rather than a simple yes-or-no headline answer.
Example 3: a user with mixed income sources
Someone with both self-employment and property income may need to think more carefully about the full qualifying-income picture rather than checking only one part of their income in isolation.
Important practical reminder
The broad answer starts with thresholds, but the safer answer still depends on qualifying-income detail
The headline rollout dates are useful, but users should still be careful before relying on a simplified reading of scope. That is especially true where qualifying income is misunderstood or where the user’s setup is less straightforward.

Good next steps
Move into the right next page once the scope picture is clearer
Some users now need a timing tool, some need the qualifying-income guide, and some need software guidance next.
Use the MTD Start-Date Checker
Best for users who understand the phased rollout and now want a practical next step on likely timing.
Read the qualifying income guide
The best follow-up if your main question is what counts towards the threshold and why qualifying income is not the same as profit.
Find compatible software
Useful when the next question is what type of software support may be needed once you are in scope.
