HMRC’s Making Tax Digital letter is an enrolment, not a filed update

An HMRC letter landing this September can look like the end of an administrative job. For some sole traders and landlords, it is closer to the beginning.

HM Revenue and Customs says it will now sign up, in stages, people who were required to use Making Tax Digital for Income Tax from 6 April 2026 but did not enrol themselves or through an agent. A confirmation may appear in HMRC online services or arrive by post.

The important distinction is what that confirmation does not do. It does not choose accounting software, authorise that software to connect to HMRC, check whether HMRC’s list of income sources is current, rebuild digital records from April or send an overdue quarterly update. Enrolment creates the route. The reporting work still has to travel along it.

The current mandatory group is made up of non-exempt sole traders and landlords whose qualifying income was more than £50,000 in the 2024 to 2025 tax year. HMRC describes qualifying income as gross income, before expenses, from self-employment and property combined.

That is not the same as profit, taxable income or everything shown on a tax return. Employment income, dividends, pensions and an individual partner’s share of partnership profit are among the sources that do not count towards this particular threshold. More than one self-employment or property source can be added together.

HMRC’s automatic sign-up is based on information it already holds, principally the 2024 to 2025 return. A business may since have changed its name or address, added a property, started another trade or stopped an income source. That is why the new guidance tells recipients to check and confirm the self-employment and property records in their online account rather than treating the letter as proof that every detail is right.

There are also exemptions. Some are automatic, while others require an application. Digital exclusion can qualify where it is not reasonable for a person to use software because of factors such as age, disability, religious belief or lack of usable internet access. HMRC says unfamiliarity with software, extra time or cost alone does not establish that exemption. Anyone who believes an automatic sign-up does not apply to their circumstances is directed by HMRC to its Self Assessment contact route or the relevant exemption guidance.

HMRC’s post-sign-up guidance separates the remaining work clearly.

First comes access to HMRC online services and confirmation of the income sources held on the account. UK properties are grouped as one UK property business, and foreign properties as one foreign property business. Separate trades still need to be represented correctly.

Second comes compatible software. HMRC does not supply it. Its software finder includes free and paid options and asks whether a product covers the relevant income sources, record-keeping method, accounting period and tax-return submission. A product already used for invoices or bookkeeping is not automatically Making Tax Digital compatible.

Third, the chosen software must be authorised to connect to HMRC. A sign-up letter is not that connection. The authorisation is what lets the software send the required information.

Fourth, digital records have to be brought up to date from the start of the tax year and any overdue quarterly update must be sent. HMRC’s new guidance expressly tells automatically enrolled people to catch up rather than wait for the next period.

This sequence is a useful defence against a misleadingly simple phrase: “HMRC has signed you up.” It describes account status, not completed compliance.

The quarterly update is a summary created by compatible software from digital records for each self-employment or property business. HMRC says it receives totals by income and expense category, not the individual receipt or invoice behind every entry. The update does not require year-end tax or accounting adjustments before it is sent.

For most people using standard tax-year periods, the first update covered 6 April to 5 July and was due on 7 August 2026. The next covers the period from 6 April to 5 October and is due on 7 November. Calendar-period users work to different period ends but the same filing deadlines. Each update is cumulative from the start of the year, rather than a sealed report for only the latest three months.

There is a limited first-year soft landing. HMRC will not apply penalty points for late quarterly updates in 2026 to 2027. That does not erase the updates or suspend the rest of Self Assessment. The final quarterly update still has to be sent before the tax return can be submitted, and penalties can still apply to a late tax return or late payment. The full tax bill remains due by 31 January after the tax year ends.

People whose income sources have stopped also need the dates to be handled accurately. HMRC says someone whose relevant sources all ended by 5 April 2026 will not need Making Tax Digital for the current year once the position is corrected. If all sources ended after 6 April, a final quarterly update is still required up to the cessation date, followed by the 2026 to 2027 tax return.

The September process closes an enrolment gap, not the reporting gap behind it. The letter confirms that HMRC has placed an account inside Making Tax Digital. The online record, software choice, authorisation, digital books and quarterly summaries remain separate objects.

That distinction also keeps the first-year penalty concession in proportion. No quarterly penalty points this year is not the same as no deadline, no records and no return. The practical story is less dramatic than a tax crackdown and more demanding than an automatic fix: one administrative step has happened, while the rest of the chain is still visible.
