If you are sole trader or landlord earning above £50,000, you will no longer rely on a once-a-year Self Assessment return. Instead, HMRC is changing to a system that demands digital record-keeping and quarterly updates, bringing tax reporting closer to real-time.

At first, switching to Making Tax Digital may feel difficult and complicated. But HMRC’s main aim is to implement MTD, to reduce errors, improve efficiency, and help taxpayers stay on top of their tax position the whole year.

What is MTD for Income Tax Self Assessment (MTD ITSA)?

MTD for Income tax self assessment (MTD ITSA) is a latest approach by the UK government to digitise the way self-employed individuals and landlords report their business income and expenses. 

Under MTD for Income Tax, taxpayers must:

• Maintain digital records of income and expenses
• Use MTD-compatible software to manage their accounts
• Submit quarterly updates to HMRC
• File a final declaration at the end of the tax year

The MTD ITSA system eliminates the need to calculate your yearly tax liabilities all at once at the end of the year.

Who Needs to Comply with MTD for Income Tax?

HMRC is introducing MTD for income tax in phases; it will be applicable to specific groups of UK taxpayers based on their income and source of earnings. 

Self-Employed Individuals

If you are a self-employed individual earning income above £50,000, then you are eligible for MTD income tax filing from April 2026. People earning income above £30,000, for them MTD for income tax will be applicable from April, 2027. For smooth tax filing you just need to maintain digital records of your business income and expenditure, and submit quarterly updates using MTD compatible software.

Landlords with Property Income

Landlords who earn more than £50,000 (as of April 2026) or £30,000 (as of April 2027) from UK or abroad property must also comply with MTD for Income Tax. They must maintain digital records of rental revenue and expenses and provide regular updates to HMRC throughout the year.

Businesses with Combined Income Sources

If you are receiving income through both self-employment and rental properties, your total income amount will help determine if you have to adhere to MTD for Income Tax. If your combined income exceeds £50,000 after April 2026 or £30,000 after April 2027, you will be required to comply with MTD by reporting all of your income in the MTD system separately from other forms of income.

MTD for Income Tax Thresholds and Eligibility

Before filing MTD for income tax it is important to know whether you are eligible for the same. HMRC is introducing the rules in phases based on threshold limits. 

Current Thresholds

• From April 2026:
  Applies to individuals earning over £50,000 annually
• From April 2027:
  Applies to individuals earning over £30,000 annually
• Future expansion (expected):
  Likely to include those earning over £20,000 (subject to confirmation)

What Counts Towards the Threshold?

Your eligibility is based on your total gross income, not profit. This includes:

• Income from self-employment
• Income from property (UK and overseas)
• Combined income from multiple sources

How MTD for Income Tax Works?

For many years, UK tax filing was a task to be done once a year. But now with changing time and technology HMRC has introduced a new approach for self-employed individuals and landlords. So, let’s understand how MTD for income tax works. 

The process of MTD for income tax works the following way:

• Keep digital records: As per HMRC, all tax-related records need to be maintained digitally using MTD Compliant software.
• Send quarterly updates to HMRC: Now you can’t be relaxed thinking, there is a lot of time left for tax reporting. Because now you need to submit summaries of your business or property income and expenses record every quarter. These updates will help HMRC to build a clearer picture of your tax position. 
• Finalise your income at year-end:  After submitting the last fourth quarter, you need to submit a final declaration. This validates your total income, claims any allowances or reliefs, and guarantees that everything is correct before your tax burden is determined.
• Pay tax as required:  Although reporting is becoming more frequent, tax payment deadlines don’t suggest that you must pay taxes four times a year. Unless HMRC rules specify differently, the final amount payable will remain based on your completed year-end status.

Basically, MTD for Income Tax converts tax reporting from a once-a-year task to an ongoing digital procedure. It is intended to eliminate errors, enhance accuracy, and assist taxpayers in staying on top of their tax responsibilities year-round.

Digital Record-Keeping Requirements Under MTD

In order to comply with MTD, businesses and individuals must follow specific digital record-keeping requirements set by HMRC. It’s mandatory to follow HMRC rules.

Here are the key requirements you need to follow:

Maintain Digital Records Only: Keep all records in digital format using MTD compatible software. If you maintain records on paper or spreadsheets, it will not be sufficient unless the spreadsheet is connected to MTD compatible software. 

Record Every Transaction:  Each income and expense must be recorded digitally with essential details, including:

• Date of transaction
• Amount
• Category (income or expense type)
• Supplier or customer details (where applicable)

Use MTD-Compatible Software

Your accounting software must be capable of:

• Storing digital records
• Sending quarterly updates to HMRC
• Submitting the final tax return
• Making corrections digitally 

Popular tools like Xero, QuickBooks, and FreeAgent are commonly used for this purpose.

Ensure Digital Links Between Systems: If you use spreadsheets and accounting software, at the same time they must be linked to each other. Manually copy pasting the data from one place to another is not allowed under MTD rules. 

Keep records updated: Records should be kept on a regular basis throughout the year, rather than only at the end. This promotes proper quarterly submissions and minimises last-minute errors.

Store Records Securely: All digital records must be kept securely and immediately available in case HMRC asks it anytime. Data security and backup technologies are essential to avoid loss or compliance issues.

Software Requirements for MTD for Income Tax

Selecting the proper software is not only beneficial, but also a requirement. HMRC expects taxpayers to use MTD-compliant software capable of handling digital record-keeping and direct submissions without manual intervention.

Here are some key requirements you need to know before choosing software:

HMRC-Recognised Software

As per HMRC rules, the software you use must be compatible with MTD. It should be able to interface directly with HMRC’s systems in order to securely submit updates and final returns.

Ability to Maintain Digital Records

Your software must have following features: 

• Record income and expenses digitally
• Categorise transactions correctly
• Store financial data in real time

This replaces traditional spreadsheets and paper-based systems.

Quarterly Submission Capability

One of the core MTD requirements is submitting updates every quarter. Your software must:

• Automatically generate summary reports
• Submit quarterly updates directly to HMRC
• Keep a record of submissions

Final Declaration & Adjustments

At the end of the tax year, the software should support:

• Finalising your income and expenses
• Making necessary adjustments (e.g., allowances, reliefs)
• Submitting the final declaration to HMRC

Error Correction and Audit Trail

Your software should allow you to:

• Correct errors without deleting original data
• Maintain a clear audit trail of changes
• Track updates for compliance purposes

Secure Data Storage

Since financial data is sensitive, your software must ensure:

• Secure cloud storage
• Regular backups
• Protection against data breaches
