You may not have registered for Making Tax Digital (MTD) yourself, but HMRC may have already added you to the system.
From 6 April 2026, MTD for Income Tax became mandatory for sole traders and landlords whose qualifying income from self-employment and property exceeded £50,000. HMRC has been reviewing information from previous Self Assessment tax returns and contacting taxpayers who appear to meet the requirements.
However, HMRC signing you up does not mean your MTD responsibilities have been completed. Automatic enrolment only deals with registration. You still need suitable software, digital records, and a process for submitting updates to HMRC.
Key Takeaways
- HMRC may automatically enrol taxpayers who appear to meet the MTD Income Tax requirements.
- The MTD threshold is based on qualifying income, not profit after expenses.
- Automatic enrolment does not create digital records or prepare quarterly updates.
- You need digital records and compatible software before submitting updates.
Why Has HMRC Signed Me Up for MTD?
HMRC introduced MTD for Income Tax to change how sole traders and landlords report their income and expenses. Instead of preparing figures once a year, qualifying taxpayers must keep digital records and provide quarterly updates using compatible software.
HMRC determines whether someone needs to join MTD by looking at qualifying income from self-employment and property. This is based on income before expenses, rather than the final taxable profit.
For example, a sole trader may have:
|
Description |
Amount |
|
Sales income |
£65,000 |
|
Business expenses |
£35,000 |
|
Final profit |
£30,000 |
Although the profit is only £30,000, the trader may still need to follow MTD rules because the qualifying income is above £50,000. HMRC uses qualifying income rather than final profit when assessing whether MTD applies.
The same applies to landlords. Rental income is considered before deducting costs such as repairs, agent fees, and other allowable expenses. A landlord receiving £55,000 in rental income may need to use MTD even if their final taxable profit is much lower.

What Does HMRC Signing You Up Actually Mean?
HMRC enrolment does not prepare your bookkeeping records or software setup or submit any quarterly updates on your behalf. You remain responsible for keeping accurate digital records and meeting the reporting requirements.
Under MTD for Income Tax, taxpayers need software that can keep digital records, connect with HMRC, and send quarterly updates. HMRC confirms that taxpayers must use compatible software to record income and expenses, submit quarterly updates, and complete their final tax return.
Instead of collecting paperwork once a year before preparing a Self Assessment return, records need to be maintained throughout the year.
What Should You Do After HMRC Signs You Up for MTD?
HMRC normally assesses eligibility using information from your previous Self Assessment tax return. For taxpayers joining from April 2026, HMRC uses qualifying income reported for the 2024/25 tax year.
The main steps are:
• Confirm your MTD position: Check that HMRC has used the correct income information and start date.
• Choose suitable software: Use MTD-compatible software that can maintain digital records and submit updates to HMRC.
• Prepare your bookkeeping: Move from year-end record keeping to regular digital bookkeeping throughout the year.
The software you choose will depend on your circumstances. A landlord with a few rental properties may need a simpler system, while a sole trader with regular transactions may require a more detailed bookkeeping setup.
Moving From Manual Records to Digital Bookkeeping
For taxpayers who currently rely on spreadsheets, paper receipts, or year-end bookkeeping, MTD requires a different approach.
A good bookkeeping process helps you:
• Understand your current tax position.
• Identify missing records earlier.
• Prepare accurate quarterly updates.
• Improve cash flow planning.
Professional bookkeeping services can help businesses maintain accurate records and prepare for the ongoing requirements of digital reporting.

What Happens If You Ignore HMRC’s MTD Registration?
If HMRC has signed you up for MTD, ignoring the notification will not remove your obligations. You still need to keep digital records, use compatible software, and submit the required information to HMRC.
For the first year of mandatory MTD for Income Tax, HMRC has confirmed that penalty points will not apply for late quarterly updates during the 2026/27 tax year. However, taxpayers must still submit their updates and continue meeting their other Self Assessment obligations.
From later years, missing quarterly update deadlines can lead to penalty points. Once a taxpayer reaches four points, HMRC can issue a £200 penalty, with further penalties possible for continued missed deadlines.

Understanding MTD Quarterly Updates
Quarterly updates are not the same as a tax return. They are summaries of your income and expenses sent to HMRC through compatible software.
For the 2026/27 tax year, the standard quarterly update deadlines are:
|
Reporting period |
Deadline |
|
6 April to 5 July 2026 |
7 August 2026 |
|
6 April to 5 October 2026 |
7 November 2026 |
|
6 April to 5 January 2027 |
7 February 2027 |
|
6 April 2026 to 5 April 2027 |
7 May 2027 |
These quarterly updates do not replace your Self Assessment tax return. You will still need to complete the final declaration and pay any tax due by the usual deadline.

Can You Be Exempt From MTD?
Not everyone must use MTD. Some taxpayers may be able to request an exemption if keeping digital records is not reasonably practical.
HMRC considers exemption requests based on individual circumstances. This may include situations involving age, disability, location, or other reasons that make digital record keeping difficult.
An exemption is not automatic. If you believe MTD is unsuitable for your circumstances, you should review your position and contact HMRC rather than simply ignoring the requirements.

Common Mistakes After HMRC Signs You Up for MTD
Many taxpayers make simple mistakes when they first move into MTD. Understanding these issues early can help avoid problems with record keeping and quarterly updates.
Assuming HMRC enrolment completes everything
Being signed up by HMRC only confirms that you need to follow MTD requirements. You still need compatible software, digital records, and a bookkeeping process that keeps your information accurate.
Checking profit instead of income
MTD eligibility is based on qualifying income, not your final profit after expenses. A business may have a lower profit after deducting costs but still fall within MTD because its income exceeds the threshold.
Waiting until the first quarterly deadline
Leaving preparation until the deadline can create unnecessary pressure. Missing receipts, incorrect transactions, and unreconciled bank entries can take time to identify and correct.
Assuming landlords are excluded
Property income can also bring individuals within MTD rules. Having rental income rather than traditional trading income does not automatically mean MTD does not apply.
Reviewing these points before your first reporting period begins can help you avoid common errors and make the transition to MTD much smoother.
HMRC Started the Process, But You Need to Prepare
If HMRC signed you up for MTD, it means HMRC believes you fall within the new digital reporting requirements. However, automatic enrolment does not complete your compliance responsibilities.
You still need accurate digital records, suitable software, and a system for managing quarterly updates. Preparing early will make the transition much smoother and help you avoid problems later.
