"If MTD applies to me, surely HMRC will tell me?"
This is one of the biggest assumptions I hear from sole traders.
And I completely understand why.
We’re used to receiving a letter when something important changes.
The good news is that HMRC has been contacting businesses that need to join Making Tax Digital for Income Tax now.
The less good news?
Whether that letter has actually reached you, been opened, or been understood is another story.
It might be sitting unopened in a pile of post.
It might have gone to an old address.
It might have been read and forgotten.
And unfortunately, not receiving (or noticing) a letter doesn't mean MTD doesn't apply.
It is still your responsibility to understand whether you need to register and comply.
Waiting for HMRC to tell you isn't really a strategy.
So who does MTD apply to?
For the first phase, it applies to sole traders and landlords with qualifying income over:
£50,000 in the 2024/25 tax year → required to join MTD now and submit the first quarterly update by the 7th August.
£30,000 in the 2025/26 tax year → required to join MTD from April 2027.
£20,000 from the 2026/27 tax year → required to join MTD from April 2028.
(These thresholds are based on qualifying income, not profit.)
If you think you might be affected, it’s worth taking ten minutes to check your 2024/2025 tax return, as well as your income in the 2025/2026 tax year.
Because knowing sooner gives you time to:
✅ Choose suitable software.
✅ Get your digital records set up.
✅ Create a bookkeeping routine.
✅ Understand what your numbers are telling you.
And actually, this is one of the positives of MTD.
Keeping your bookkeeping up to date isn't just about satisfying HMRC.
It means you can see how your business is performing throughout the year, spot issues earlier, and make better decisions.
No more waiting until January to discover what happened last year.
Have you checked whether MTD applies to you yet, or were you waiting for HMRC to let you know?
