MTD for Self Assessment: Everything You Need to Know

Making Tax Digital (MTD) is one of the biggest changes to the UK tax system in recent years. It is designed to make tax reporting more accurate, efficient, and easier to manage.

For many self-employed individuals and landlords, the latest major milestone was April 2026, when MTD for Income Tax Self Assessment (ITSA) became mandatory for qualifying taxpayers.

However, as of March 2026, 800,000 tax payers are yet to join MTD. So, if you haven’t started yet, you need to act now.

MTD for Self Assessment: Everything You Need to Know

What Is MTD for Self Assessment?

Making Tax Digital for Self Assessment is HMRC’s initiative to move taxpayers away from paper-based records and annual tax returns towards a fully digital reporting system.

Understanding Making Tax Digital for Self Assessment

Under MTD for Self Assessment, qualifying taxpayers must keep digital records and use compatible software to submit information to HMRC throughout the year.

The goal is to reduce errors, improve tax accuracy, and give taxpayers a clearer picture of their tax position. Unlike the current Self Assessment process, which involves submitting a single annual return, MTD requires more regular reporting.

What Is MTD for ITSA?

MTD for ITSA stands for Making Tax Digital for Income Tax Self Assessment. It applies to self-employed individuals and landlords who meet HMRC’s income thresholds. Instead of completing a traditional annual Self Assessment tax return, taxpayers will need to maintain digital records and submit quarterly updates through approved software.

Who Must Comply with MTD for Income Tax from April 2026?

Not everyone will be affected immediately. HMRC is introducing MTD for Income Tax in stages.

Self-Employed Individuals

From April 2026, self-employed individuals with qualifying income above £50,000 are now required to comply with MTD requirements.

This includes sole traders operating across a wide range of industries, from consultants and tradespeople to freelancers and online sellers.

Landlords

Landlords with qualifying income above the threshold will also need to comply.

This applies to individuals earning income from residential or commercial property rentals and who currently complete a Self Assessment tax return.

Income Thresholds and Eligibility Rules

The initial threshold is:

  • April 2026: Income over £50,000
  • April 2027: Income over £30,000

HMRC has also announced plans to extend this further in the future, meaning more taxpayers are likely to be brought into MTD over time.

MTD Self Assessment Deadline Dates

Date Requirement
April 2026 MTD becomes mandatory for taxpayers with qualifying income over £50,000
April 2027 Threshold expands to taxpayers with income over £30,000
Future Updates Further HMRC rollout expected for additional taxpayers

If you haven’t already prepared, it’s important to act now. Delays can leave you scrambling to implement software, digitise records, and meet reporting obligations.

What Are the HMRC MTD Requirements

To comply with Making Tax Digital, taxpayers must meet several key requirements.

Maintain Digital Tax Records

Records must be kept digitally rather than manually.

Examples include:

  • Sales and income records
  • Business expenses
  • Property income
  • Allowable deductions
  • Bank transaction information

Submit Quarterly Tax Updates

Rather than submitting information once a year, taxpayers must provide quarterly updates to HMRC.

These updates include summaries of income and expenses recorded during each reporting period.

Final Declaration Process

At the end of the tax year, taxpayers must submit a final declaration. This confirms all income sources, claims, adjustments, and reliefs.

How MTD for Self Assessment Works

The process is designed to be straightforward once the right systems are in place.

Step 1: Record Income and Expenses Digitally

Keep accurate digital records using MTD-compatible software.

Step 2: Send Quarterly Updates to HMRC

Submit summaries of your income and expenses every quarter.

Step 3: Review and Submit Final Declaration

Confirm your annual figures and make any necessary adjustments.

Step 4: Pay Your Tax Bill

Once your tax position has been finalised, pay any tax due by the relevant deadline.

Do You Need Software for Making Tax Digital for Self Assessment?

Yes. HMRC requires taxpayers to use compatible software to meet MTD obligations.

Why Spreadsheets Alone May Not Be Enough

While spreadsheets can still play a role in some circumstances, they generally require additional bridging software to meet HMRC’s digital requirements.

For many taxpayers, dedicated accounting software provides a simpler and more efficient solution.

Features to Look for in MTD-Compatible Software

When choosing software, look for features such as:

  • Digital record-keeping
  • Direct HMRC integration
  • Automated submissions
  • Tax estimates and reporting
  • Bank feeds and reconciliation tools

Benefits of Using Cloud Accounting Software

Cloud accounting software offers many advantages:

  • Real-time access to financial information
  • Reduced manual administration
  • Better financial visibility
  • Improved accuracy
  • Easier compliance with HMRC requirements

How to Prepare for the MTD for Self Assessment Deadline

The sooner you prepare, the easier it will be.

Consider the following steps:

  • Review your current record-keeping processes
  • Choose MTD-compatible software
  • Start keeping digital records now
  • Seek professional accounting support
  • Train staff where necessary
  • Familiarise yourself with quarterly reporting requirements

Taking action now can help avoid compliance issues and make the transition significantly easier.
