HMRC to Automatically Enrol Eligible Taxpayers into MTD IT: What You Need to Know
HMRC is no longer leaving every Making Tax Digital for Income Tax sign-up to the taxpayer. If HMRC believes someone should be within MTD IT and they have not registered, it may start the process for them.
That matters because automatic enrolment does not remove the obligations. It simply means HMRC thinks the taxpayer falls within the rules and is being brought into the system. The next step is still practical: checking the details, using compatible software, keeping digital records, and meeting the new reporting duties.
MTD IT, short for Making Tax Digital for Income Tax, is one of the biggest changes to Self Assessment for sole traders and landlords. For many people, the issue will not be whether they have heard about it. It will be whether HMRC believes their income puts them in scope.
What automatic enrolment means
Automatic enrolment means HMRC may sign up a taxpayer to MTD IT where its records suggest they meet the criteria and have not already registered themselves.
This does not mean HMRC has done the bookkeeping work. It does not mean the taxpayer has chosen software. It also does not mean HMRC’s information is guaranteed to be right.
It means HMRC has used the information it holds, usually from Self Assessment returns, to identify people who appear to fall within the rules. If that applies, HMRC may contact the taxpayer to explain that they have been enrolled or are being moved towards enrolment.
The key point is simple: do not ignore HMRC correspondence about MTD IT. A letter, email, or message in an online tax account may need checking quickly, especially if the taxpayer believes they should not be in scope.
Who is likely to be affected
MTD IT applies to individuals who receive income from self-employment, property, or both, once their qualifying income is above the relevant threshold.
The current timetable is being phased in by income level:
Start date | Who is expected to be in scope |
6 April 2026 | Sole traders and landlords with qualifying income over £50,000 |
6 April 2027 | Sole traders and landlords with qualifying income over £30,000 |
6 April 2028 | Sole traders and landlords with qualifying income over £20,000 |
Qualifying income generally means total gross income from self-employment and property before deducting expenses. For example, a person with £35,000 of rental income and £18,000 of sole trade income may need to look at the combined amount, not each source in isolation.
HMRC will usually base its view on tax return data it already holds. That can create problems where circumstances have changed. Someone may have sold a rental property, stopped trading, reduced their hours, or made a one-off disposal that makes the figures look unusual.
That is why automatic enrolment should be treated as a prompt to check, not as a final answer.
What changes once someone is in MTD IT
MTD IT changes the rhythm of tax reporting. Instead of keeping records however they choose and filing one annual Self Assessment return, taxpayers in scope need to keep digital records and use compatible software to send updates to HMRC.
The main duties include:
Keeping business or property records digitally
Using software that works with HMRC’s MTD system
Sending quarterly updates during the tax year
Submitting a final declaration after the end of the tax year
Keeping records accurate enough to support the figures reported
The quarterly updates are not the same as full tax returns. They are a regular summary of income and expenses. The year-end process still matters because adjustments, allowances, reliefs, and other income may need to be included before the final tax position is settled.
For many taxpayers, the biggest change will be habit. Leaving records until January will no longer work well. Bank transactions, invoices, rent receipts, mileage, repairs, stock costs, and other expenses will need to be recorded throughout the year.
What to do if HMRC enrols you automatically
If HMRC contacts you about automatic enrolment, start by checking the basics.
Check the income figure HMRC has used. Compare it with the most recent Self Assessment return and current trading or property income. Look at gross income before expenses, as this is often where misunderstandings arise.
Check whether your circumstances have changed. If you have stopped trading, sold a rental property, or expect income to fall below the threshold, you may need to tell HMRC or seek advice.
Check your software position. Spreadsheets may still be part of the process for some people, but the submission to HMRC must be made through compatible software or bridging software that meets MTD rules.
Check who will file the updates. If an accountant or bookkeeper deals with your tax, confirm whether they will handle the quarterly submissions and what information they need from you.
Check your Government Gateway access. Make sure login details are up to date and that the correct tax account is accessible. Problems with access can turn a simple enrolment issue into a last-minute scramble.
What if HMRC is wrong
HMRC can only work from the information it holds. That information may be out of date or incomplete.
If you believe you have been enrolled incorrectly, do not assume it will sort itself out. Gather the reason clearly. For example:
The trade has ceased
The rental property has been sold
The income figure includes something that should not count
The income was temporary and is no longer expected
HMRC has linked the wrong income source
Keep copies of any correspondence. If you speak to HMRC, note the date, time, and what was said. If an agent acts for you, share the HMRC message with them as soon as possible.
This is also a good time to check whether past Self Assessment returns describe the income correctly. Small classification errors can have bigger effects once HMRC starts using return data to trigger digital reporting obligations.
Why early preparation matters
The risk with MTD IT is not only penalties or missed deadlines. The bigger issue is poor information. If records are rushed, quarterly updates may be wrong, year-end corrections may be harder, and cash flow planning may suffer.
A simple preparation plan can make the change easier:
Review income sources and thresholds.
Choose suitable software before the start date.
Set up bank feeds or a regular record-keeping routine.
Separate personal and business costs where possible.
Decide who is responsible for each submission.
Keep evidence for expenses as you go.
The earlier this is done, the less dramatic automatic enrolment becomes. It turns from a surprise into an admin change that can be managed.
The takeaway
HMRC to Automatically Enrol Eligible Taxpayers into MTD IT is a clear sign that the new system is moving from future planning to real administration.
If HMRC thinks a taxpayer should be in MTD IT, the safest response is to check the position rather than wait. Confirm the income, review the rules, put digital records in place, and question the enrolment if the facts are wrong.
