If you’ve been seeing “MTD for Income Tax” pop up more and more and quietly wondering whether it’s about to land on your lap too, you’ve come to the right place. 

Although there’s been a lot of marketing and publication about this new HMRC Making Tax Digital update, many small business owners are asking themselves if it applies to them.

This is where confusion often starts to creep in, especially around MTD for Income Tax as a Limited company, because at first glance it feels like it should apply to companies… but it doesn’t work quite like that.

First things first, what is MTD for Income Tax?

You might see it being called a few different things. Some of the most common names given are Making Tax Digital for Income Tax Self Assessment (MTD ITSA for short) or Making Tax Digital for Income Tax (MTD for IT). They all refer to the new system from HMRC that changes how some people report their income.

Instead of the once-a-year Self Assessment, it involves:

• Keeping digital records with MTD-compatible software.
• Sending quarterly reports to HMRC of your income and expenses.
• Submitting a Final Declaration, which will eventually replace the tax return. 

In other words, it’s designed to move things away from the January panic and towards more regular updates throughout the year. The idea is that both you and HMRC stay closer to your actual tax position, so there are fewer surprises at year-end. In theory, that sounds reassuring. In practice, it’s left a lot of people feeling a bit unsure about the extra admin.

Who does it affect?

This is the bit that actually matters, because despite all the noise around MTD, it’s not a blanket rule hitting everyone at once. It’s very targeted right now.

MTD for Income Tax is being introduced in stages by HMRC, which basically means: some people are in, some people are not, and some people won’t be for a while yet.

For the 2026/2026 tax year:

You only fall under MTD for Income Tax rules this tax year if you had qualifying income over £50,000 in the 2024/25 tax year. If you’re below that, you don’t have to fulfil the MTD ITSA rules. 

What counts as qualifying income?

This is where people often trip up, because not all income is treated the same. Income is only counted for the £50,000 threshold if it comes from self-employment income (Sole Trader profits) or from personal property income. 

What isn’t included?

Anything earned through salary, dividends, or other non Self Assessment income sources do not count. So it’s not your “everything you earn everywhere” figure, it’s a specific slice of your income.

You could technically earn a high salary, take dividends and still not meet the MTD for Income Tax threshold because your self-employed income and personal rental income fall below the £50k.

So where do contractors fit in?

This is usually the moment where things either click… or get slightly more confusing before they click.

Let’s split it properly.

If you’re a Sole Trader Contractor

Although Contractors usually prefer to operate as Limited Companies, there are some examples where people opt to remain a Sole Trader. 

In this example, MTD for Income Tax can start to apply:

• Your trading profit counts as “qualifying income”.
• If that profit is over £50,000 → you’re in scope for MTD.
• If it’s under £50,000 → you’re not in yet.

So it’s not about your total lifestyle income, savings, or anything else. It’s just your self-employment profit.

If you’re a Limited Company Contractor

If you’re looking at MTD for Income Tax as a Limited company, things are much simpler than they first appear:

• Your company profits do not count as “qualifying income” for MTD for Income Tax.
• Salary through PAYE is excluded.
• Dividends are also excluded.

So even if you’re earning well through your company, that £50,000 MTD threshold doesn’t apply to you. The only exceptions are if you earn a personal rental income or income from self-employment outside of your Limited Company. 

Example scenarios

Here’s how the £50,000 “qualifying income” rule plays out in real life:

What this actually means

The £50,000 figure gets all the attention, but it’s really just a trigger point, not the full picture.

MTD for Income Tax is only focused on specific types of income, mainly self-employment profits and personal property income. That’s what “qualifying income” refers to, not everything you earn across the board.

So in practice:

• If you’re over £50,000 in qualifying income → you’ll fall under MTD for Income Tax in stages.
• If you’re under £50,000 → nothing changes for now.
• If your income is inside a Limited Company → it’s not part of this system at all.

And that last one is where most of the confusion comes from. A lot of contractors and directors assume MTD is about total earnings, but it isn’t. It’s about how HMRC categorises that income.

So it’s less of a sweeping overhaul and more of a targeted shift for Sole Traders and landlords first. If you’re running a Limited Company, including those searching for MTD for Income Tax as a Limited company, it’s still something to be aware of, but not something you need to act on today.
