What Are the New MTD for Income Tax Software Requirements After HMRC's June 2026 Update?

Understanding HMRC's June 2026 MTD for Income Tax Update

HMRC's Making Tax Digital (MTD) for Income Tax Self Assessment (ITSA) initiative continues to evolve, with a significant update rolled out on 16 June 2026. This deployment introduced key enhancements aimed at strengthening the service's underlying infrastructure and improving the experience for both software developers and end-users. The core message from HMRC is a reinforcement of the need for compliant software, which is the cornerstone of the MTD regime. These updates are not merely technical adjustments; they signify a maturing of the MTD ITSA platform, requiring software solutions to meet increasingly robust standards for digital record keeping, data submission, and user functionality.

For sole traders and landlords, these enhancements directly impact the capabilities and reliability they should expect from their MTD-compatible software. The updates touch upon critical areas such as the minimum functionality standards that software must adhere to, the processes by which software gains production access to HMRC's live systems, the ability for taxpayers to view their penalty position, and the accurate capture of accounting periods. All systems are now operating as expected, underscoring HMRC's commitment to a stable and efficient digital tax environment. This guide will delve into the implications of these changes, outlining what these new requirements mean for your MTD for Income Tax software and how AccountsOS is designed to meet and exceed these evolving standards.

The Broader Context of Making Tax Digital for Income Tax Self Assessment (MTD ITSA)

Before examining the specifics of the June 2026 update, it is crucial to understand the overarching framework of MTD ITSA. This initiative is a fundamental shift from the traditional annual Self Assessment tax return towards a more frequent, digital, and integrated approach to tax reporting. HMRC's goal is to make tax administration more efficient, reduce errors, and provide taxpayers with a clearer, near real-time view of their tax position.

What is MTD ITSA?

MTD ITSA requires eligible sole traders and landlords to:

1. Keep Digital Records: Maintain records of all business income and expenses using MTD-compatible software. This means moving away from paper records or standalone spreadsheets without digital links.
2. Send Quarterly Updates: Submit summaries of their business income and expenses to HMRC every three months, directly from their MTD-compatible software.
3. Submit an End of Period Statement (EOPS): After the final quarterly update for the tax year, an EOPS must be submitted to finalise the business's profits and losses, making any necessary accounting adjustments.
4. Submit a Final Declaration: This replaces the traditional Self Assessment tax return. It combines all other income sources (e.g., employment, savings, dividends) and claims for allowances and reliefs, providing a comprehensive view of the taxpayer's total income and tax liability.

MTD ITSA Implementation Timeline

The rollout of MTD ITSA has been phased, with specific income thresholds determining when businesses become mandated:

Group	Gross Income Threshold	Mandation Date
Self-employed & Landlords	Over £50,000	April 2026
Self-employed & Landlords	Between £30,000 and £50,000	April 2027
Self-employed & Landlords	Under £30,000	Date TBC (Voluntary Opt-in available)

The June 2026 update occurs precisely as the first wave of sole traders and landlords with gross income over £50,000 are becoming mandated. This timing underscores the importance of the update in ensuring the stability and functionality of the MTD ITSA service for its initial broad implementation.

Key Benefits of MTD ITSA

For compliant software users, MTD ITSA is designed to offer several advantages:

• Reduced Errors: Digital record keeping and direct submission minimise manual data entry errors.
• Real-time Insights: Quarterly updates provide a more up-to-date picture of tax liability, aiding financial planning and budgeting.
• Simplified Compliance: A structured, digital process aims to make tax reporting less burdensome over time.
• Improved Transparency: Access to digital tax accounts and penalty information (now enhanced by the June 2026 update) offers greater clarity.

The June 2026 enhancements are integral to delivering these benefits reliably and effectively.

What Were the Specific Enhancements in the June 2026 Update?

HMRC's announcement highlighted four key areas of enhancement: minimum functionality standards, production access processes, penalty position viewing, and period-of-account capture. While the summary is brief, the implications for MTD-compliant software and its users are significant. These updates reflect HMRC's ongoing efforts to refine the MTD ITSA service, ensuring it is robust, user-friendly, and capable of handling the diverse needs of sole traders and landlords.

1. Enhanced Minimum Functionality Standards

The phrase "minimum functionality standards" refers to the baseline capabilities that any MTD-compatible software must possess to interact with HMRC's MTD platform. These standards cover everything from how data is recorded and stored to how it is categorised and submitted. The "enhancement" of these standards in June 2026 implies a raising of the bar, ensuring that software provides a more comprehensive, accurate, and reliable experience.

What Minimum Functionality Entails (Pre- and Post-Update):

• Digital Record Keeping: Software must enable users to digitally record all income and expenses. This includes:
  • Transaction Capture: Recording individual transactions (sales, purchases, bank transfers).
  • Categorisation: Assigning transactions to appropriate HMRC-defined expense categories (e.g., travel, office costs, professional fees).
  • Digital Storage: Storing digital copies of invoices and receipts, often linked to transactions.
  • Bank Feeds: Integration with bank accounts to import transaction data automatically.
• Preparation of Quarterly Updates: The software must be able to compile the digitally recorded data into the required summary format for quarterly submissions.
• Submission to HMRC: A secure and direct digital link to HMRC's MTD platform for sending quarterly updates, EOPS, and Final Declarations.
• Receipt of HMRC Information: The ability to receive and display information from HMRC, such as confirmation of submissions and potentially tax estimates.

How the June 2026 Update Strengthens These Standards:

The enhancement likely translates into:

• Richer Data Validation: Software now needs to perform more rigorous checks on data accuracy and completeness before submission, reducing errors at the source. This could involve more sophisticated rules for categorisation, preventing common mistakes, or flagging unusual entries for review.
• Improved User Interface/Experience (UI/UX) Requirements: HMRC may have specified clearer guidelines for how MTD software presents information to users, ensuring transparency and ease of use, particularly around complex areas like adjustments or allowances.
• Greater Granularity in Reporting: The updates might require software to capture or present certain data points with more detail, aiding HMRC's analysis and ensuring more precise tax calculations.
• Enhanced Audit Trail Capabilities: Software may now need to provide more robust audit trails, documenting every transaction, adjustment, and submission, making it easier for users and HMRC to trace financial activities.
• More Robust Error Handling: Improved standards mean software should provide clearer, more actionable feedback when errors occur, guiding users to correct issues efficiently rather than encountering generic failure messages.

For users, this means that compliant software should now offer a more resilient, accurate, and user-friendly experience, reducing the likelihood of errors and making the MTD process smoother.

2. Improved Production Access Processes

"Production access processes" refer to the mechanisms and protocols that software developers use to connect their MTD-compatible applications to HMRC's live (production) MTD ITSA system. This is the pipeline through which your quarterly updates and other submissions travel from your software to HMRC.

What Production Access Entails:

• API Integration: Software uses Application Programming Interfaces (APIs) provided by HMRC to communicate securely with the MTD platform.
• Testing and Certification: Before gaining full production access, software must undergo rigorous testing to ensure it meets all functional and security requirements.
• Security Protocols: Adherence to strict security standards to protect taxpayer data during transmission and storage.

How the June 2026 Update Impacts Production Access:

The improvements in this area are primarily for software developers, but they have direct benefits for end-users:

• Enhanced Reliability of Submissions: Streamlined and more robust production access processes mean that data transfers from your software to HMRC are less prone to technical glitches, downtime, or delays. This ensures your quarterly updates and other submissions are received reliably and on time.
• Faster Rollout of Updates: As HMRC continues to refine MTD ITSA, improved production access allows software developers to integrate new features and compliance updates more quickly and seamlessly, ensuring your software remains current.
• Increased System Stability: Better processes for managing software connections contribute to the overall stability of the MTD ITSA platform, reducing the risk of system-wide issues that could affect multiple users.
• Stronger Security: Enhanced access protocols can also imply strengthened security measures, further protecting your financial data as it moves between your software and HMRC.
• Reduced Development Burden: For software providers like AccountsOS, more efficient access processes mean development resources can be focused on user-facing features and support, rather than troubleshooting integration issues.

In essence, improved production access translates into a more stable, secure, and efficient MTD service for everyone using compliant software.

3. Penalty Position Viewing

This enhancement is a significant direct benefit for taxpayers. Historically, understanding one's penalty position with HMRC often involved receiving letters or navigating complex online portals. The June 2026 update introduces functionality that allows for clearer visibility of penalties.

Implications for MTD Software and Users:

• Integrated Penalty Information: MTD-compliant software can now potentially integrate with HMRC's systems to display a user's current penalty position directly within the application. This could include:
  • Notification of Late Submissions: Alerts for missed quarterly updates or deadlines.
  • Details of Penalties Incurred: The type of penalty (e.g., late filing, late payment), the amount, and the reason.
  • Outstanding Penalty Balances: A clear view of what penalties are owed.
• Proactive Management: By having this information readily available in their accounting software, users can:
  • Identify Issues Early: Spot potential penalties before they escalate.
  • Take Corrective Action: Respond to HMRC's notifications or rectify errors promptly.
  • Budget for Penalties: Understand their financial obligations more clearly.
• Improved Transparency: This functionality enhances transparency between HMRC and taxpayers, fostering better compliance by making the consequences of non-compliance more visible and understandable.
• Educational Tool: Software can leverage this information to educate users on common pitfalls and best practices for avoiding penalties. For example, AccountsOS could display a dashboard showing upcoming deadlines and potential penalty risks if those deadlines are missed.

This enhancement directly addresses one of the major concerns for taxpayers transitioning to MTD ITSA: the increased frequency of submissions and the potential for more penalties. By making penalty information more accessible, HMRC aims to empower taxpayers to manage their compliance proactively.

4. Enhanced Period-of-Account Capture

The "period of account" refers to the financial year a business uses for its accounting. For many sole traders, this aligns with the tax year (6 April to 5 April). However, some businesses have different year ends. With the introduction of Basis Period Reform alongside MTD ITSA, accurately capturing and reporting on different periods of account has become even more critical.

Context: Basis Period Reform

Effective from the 2024/25 tax year, Basis Period Reform fundamentally changes how self-employment and partnership profits are taxed, moving from a "current year basis" to a "tax year basis." This means:

• Tax Year Basis: Taxable profits for a given tax year (e.g., 2026/27) will be the profits arising in that specific tax year, regardless of the business's accounting period end date.
• Apportionment: If a business's accounting period does not align with the tax year (e.g., a 31 March year end), profits will need to be apportioned across tax years.
• Transition Year (2023/24): This was a complex year where businesses had to report profits from their usual accounting period plus any "overlap profits" to bring them up to date with the 5 April 2024 tax year end.

How the June 2026 Update Enhances Period-of-Account Capture:

The enhancement signifies that MTD software must now be even more sophisticated in how it handles and reports accounting periods, especially in light of Basis Period Reform:

• Accurate Apportionment Tools: Software needs robust functionality to accurately apportion profits and losses across tax years when the accounting period does not match the tax year. This involves precise date calculations and potentially complex adjustments.
• Clear Reporting of Accounting Periods: The software must clearly define and manage the start and end dates of a business's accounting period, as well as the relevant tax year periods.
• Handling Overlap Relief: While the main transition year for Basis Period Reform was 2023/24, software still needs to manage any remaining overlap relief that can be used to reduce taxable profits in future years, particularly in the MTD ITSA context.
• Simplified Adjustments: The software should facilitate any necessary adjustments to bring the business's profit/loss calculation into line with the tax year basis for MTD ITSA submissions.
• User Guidance: Compliant software should provide clear guidance and intuitive workflows for users whose accounting periods do not align with the tax year, helping them navigate the complexities of apportionment and reporting.

This enhancement ensures that MTD software can reliably and accurately report profits under the new tax year basis, regardless of a business's chosen accounting period, which is a critical aspect of MTD ITSA compliance.

Core MTD for Income Tax Software Requirements in Detail

Beyond the specific June 2026 updates, there are fundamental requirements that any MTD-compliant software must meet. These form the bedrock of the digital tax system and are now expected to be delivered with even greater precision and reliability following HMRC's enhancements.

1. Digital Record Keeping

This is the absolute foundation of MTD ITSA. Software must enable comprehensive digital record keeping for all relevant business transactions.

What to Record Digitally:

• Income: All sales, fees, grants, and other revenue generated by the business. This includes the date, amount, and category of income.
• Expenses: All allowable business expenses, including the date, amount, supplier, and expense category.
• Asset Purchases: Details of capital expenditure (e.g., equipment, vehicles) for capital allowance calculations.
• Other Financial Data: Bank interest received, dividend income, and any other relevant financial transactions.

Digital Link Requirement:

HMRC's MTD rules stipulate that data must be digitally linked from its source (e.g., bank feed, invoice scan) through to the MTD submission. This means:

• No Manual Transcription: Data should flow automatically or through secure digital transfers, minimising the need for manual re-keying which can introduce errors.
• Integrated Systems: Software should ideally integrate with bank accounts, payment processors, and other relevant platforms to automate data capture.
• Digital Storage of Source Documents: The ability to attach or link digital copies of receipts and invoices to transactions provides a robust audit trail.

2. Quarterly Updates

These are the regular submissions to HMRC that replace the annual summary of income and expenses.

Content of Quarterly Updates:

Each quarterly update must provide a summary of the income and expenses for the specified period. The breakdown of expenses usually follows HMRC's standard categories.

Quarterly Periods and Deadlines:

The quarterly periods are fixed based on the tax year (6 April to 5 April), regardless of a business's accounting period.

Quarterly Period	Deadline
6 April - 5 July	5 August
6 July - 5 October	5 November
6 October - 5 January	5 February
6 January - 5 April	5 May

Software's Role:

• Automated Compilation: Software should automatically compile the digitally recorded transactions into the correct summary format for each quarter.
• One-Click Submission: The goal is for software to facilitate easy, secure submission of these summaries to HMRC with minimal user intervention once the data is reviewed.
• Real-time Tax Estimate: Many software solutions will provide an estimated tax liability based on the quarterly data, helping users plan for tax payments.

3. End of Period Statement (EOPS)

The EOPS is submitted after the final quarterly update for a tax year and is specific to each business.

Purpose of EOPS:

• Finalise Business Profits/Losses: This statement allows for any final accounting adjustments that may not have been included in the quarterly updates.
• Claim Allowances: This is where capital allowances and other business-specific reliefs are claimed.
• Adjustments: Any adjustments for private use of assets, stock valuations, or other year-end accounting entries are made here.

Software's Role:

• Facilitating Adjustments: Software must provide clear mechanisms for users or their agents to enter year-end adjustments.
• Calculating Final Profit/Loss: Automatically calculate the final taxable profit or loss for the business after all adjustments and allowances.
• Submission: Securely submit the EOPS to HMRC.

4. Final Declaration

This is the ultimate submission that replaces the traditional Self Assessment tax return.

Content of Final Declaration:

• All Income Sources: Combines the finalised business profits (from the EOPS) with all other taxable income (e.g., employment income, property income from other MTD businesses, savings interest, dividends, foreign income, capital gains).
• Allowances and Reliefs: Claims for personal allowances, pension contributions, gift aid, and any other relevant tax reliefs.
• Calculation of Total Tax Liability: The software (or HMRC's system via the software) will calculate the final Income Tax and National Insurance Contributions due.

Software's Role:

• Consolidation: Consolidate all income and deductions from various sources.
• Tax Calculation: Perform or display the final tax calculation.
• Payments on Account: Display information regarding payments on account and any balancing payment due.
• Submission: Securely submit the complete Final Declaration to HMRC.

5. Digital Links and Data Integrity

The June 2026 update, particularly around minimum functionality and production access, reinforces the importance of robust digital links and data integrity.

• Automated Data Transfer: Data should move between different parts of the software (e.g., from transaction entry to quarterly summary) and from the software to HMRC's systems without manual re-entry.
• Error Prevention: The software should incorporate features that minimise errors, such as data validation rules, automatic reconciliation, and clear alerts for discrepancies.
• Audit Trail: A clear, unalterable audit trail of all transactions and submissions is crucial for compliance and for responding to any HMRC queries.

Meeting these core requirements, now with the added robustness of the June 2026 enhancements, is essential for any MTD-compliant software.

Who Needs to Comply with MTD for Income Tax?

Understanding the mandation thresholds and categories is vital for sole traders and landlords to determine their compliance obligations. The June 2026 update applies to the MTD ITSA service that these groups will be using.

Income Thresholds for Mandation

• Gross Income Over £50,000: From April 2026, self-employed individuals and landlords whose gross income from all businesses and properties exceeds £50,000 in a tax year must comply with MTD ITSA. Gross income here means total turnover before any expenses.
• Gross Income Between £30,000 and £50,000: From April 2027, those with gross income in this bracket will become mandated.
• Gross Income Under £30,000: A mandation date for this group is yet to be confirmed. However, these individuals can choose to opt in voluntarily to MTD ITSA if they wish to benefit from digital record keeping and more frequent updates.

What Counts as 'Gross Income'?

For the purpose of MTD ITSA mandation, 'gross income' includes:

• Self-employment Income: All turnover from your sole trader business(es).
• UK Property Income: All gross rental income from UK property.
• Overseas Property Income: All gross rental income from overseas property.

If you have multiple self-employment businesses or multiple properties, all gross income from these sources is combined to determine if you meet the threshold.

Example: A sole trader has gross income of £35,000 from their freelance work and £20,000 from a rental property. Their total gross income is £55,000. This means they will be mandated for MTD ITSA from April 2026.

Exemptions from MTD ITSA

Certain individuals and entities are currently exempt from MTD ITSA:

• Non-UK Residents: Individuals who are not UK residents for tax purposes.
• Estates, Trusts, and Charities: These entities have different tax reporting requirements.
• Limited Companies: Limited companies are subject to MTD for VAT and eventually MTD for Corporation Tax, but not MTD ITSA.
• Individuals with 'No Digital Capability': HMRC may grant exemptions in rare cases where it is genuinely not practicable for an individual to comply digitally due to age, disability, or remoteness of location. This is usually determined on a case-by-case basis.

Voluntary Adoption

Even if you don't meet the mandation thresholds, you can choose to comply with MTD ITSA voluntarily. This can be beneficial for businesses looking to streamline their accounting, reduce errors, and gain better financial insights. Using MTD-compliant software from an early stage can help businesses prepare for future mandation and improve their overall financial management.

Choosing MTD-Compliant Software After the June 2026 Update

With the MTD ITSA service becoming more refined and robust following the June 2026 updates, selecting the right MTD-compliant software is more critical than ever. Your chosen solution must not only meet the fundamental MTD requirements but also incorporate the enhanced functionalities for reliability, penalty visibility, and accurate period-of-account capture.

Key Features to Look for in MTD-Compliant Software:

   • Confirmation of Submissions: Clear confirmation that submissions have been successfully sent and received by HMRC.
4. Period-of-Account Management:
   • Flexible Accounting Periods: Support for businesses with non-standard accounting period end dates, including robust apportionment tools for Basis Period Reform.
   • Overlap Relief Tracking: Ability to track and apply any remaining overlap relief.
   • Year-End Adjustments: Intuitive tools for making accounting adjustments required for the EOPS.
5. Penalty Position Visibility (Post-June 2026):
   • Integrated Alerts: Notifications within the software about potential or actual penalties.
   • Penalty Dashboard: A clear overview of your penalty status, reasons, and amounts due.
   • Deadline Reminders: Proactive alerts for upcoming MTD deadlines (quarterly, EOPS, Final Declaration).
6. Reporting and Insights:
   • Real-time Profit & Loss: Up-to-date view of your business's financial performance.
   • Estimated Tax Liability: Dynamic calculation of your estimated Income Tax and National Insurance contributions throughout the year.
   • Customisable Reports: Ability to generate various financial reports for business analysis.

   • Data Encryption: Robust encryption for all data, both in transit and at rest.
   • Two-Factor Authentication (2FA): Enhanced login security.
   • GDPR Compliance: Adherence to data protection regulations.

Bridging Software vs. Full Accounting Software

• Bridging Software: These solutions act as a link between a spreadsheet (where you keep your records) and HMRC's MTD system. They take the summary data from your spreadsheet and submit it in the MTD-compliant format. While a temporary solution for some, they still require accurate spreadsheet management and do not offer the full benefits of integrated accounting.
• Full Accounting Software (e.g., AccountsOS): These are comprehensive platforms that handle all aspects of digital record keeping, transaction categorisation, reporting, and MTD submissions. They offer a more automated, efficient, and error-reducing solution, fully embracing the spirit of MTD ITSA. The June 2026 updates further cement the need for such robust, integrated solutions that can handle enhanced functionality and complex data flows reliably.

Ultimately, the choice of software will depend on the complexity of your business, your comfort with technology, and your budget. However, with MTD ITSA becoming mandatory for more businesses, investing in a robust, MTD-compliant accounting solution is a strategic decision that offers long-term benefits in terms of compliance, efficiency, and financial insight.

Preparing for MTD for Income Tax with Enhanced Software Requirements

The June 2026 update signals that MTD ITSA is a sophisticated and continually improving system. Preparing for compliance means more than just buying software; it involves adapting your business processes and understanding the new requirements.

Steps to Take Now:

1. Assess Your Mandation Date: Confirm when you are mandated to join MTD ITSA based on your gross income. Even if it's 2027 or later, early preparation is highly recommended.
2. Digitalise Your Current Records: Start moving away from paper or non-digital spreadsheets. Begin scanning receipts, using online banking for all business transactions, and adopting digital invoicing. This will make the transition to MTD software much smoother.
3. Choose MTD-Compliant Software: Research and select a software solution that not only meets HMRC's basic MTD requirements but also offers the enhanced functionalities highlighted by the June 2026 update. Look for features like robust bank feeds, intelligent categorisation, and clear reporting of tax positions and potential penalties.
4. Understand Your Accounting Period: If your business has a non-standard accounting period, ensure you understand how Basis Period Reform impacts you and how your chosen software will handle the necessary apportionment.
5. Educate Yourself and Your Team: Familiarise yourself with the concepts of quarterly updates, EOPS, and the Final Declaration. If you have staff, ensure they understand their role in digital record keeping.
6. Review Your Chart of Accounts: Ensure your income and expense categories align with HMRC's requirements for MTD ITSA. MTD-compliant software like AccountsOS will guide you on this.
7. Consider Professional Advice: If your tax affairs are complex, or if you feel overwhelmed by the changes, consult with an accountant or tax advisor who is knowledgeable about MTD ITSA. They can help you choose the right software and ensure you are fully compliant.
8. Trial and Error: If possible, start using your chosen software for a few months before your mandation date. This allows you to get comfortable with the system, identify any issues, and practice the digital record-keeping and submission processes without the pressure of a live deadline.

Record-Keeping Best Practices Under MTD:

• Daily or Weekly Updates: Don't let your record keeping pile up. Regular entry of income and expenses makes quarterly submissions much easier.
• Detailed Descriptions: Add clear descriptions to your transactions to aid categorisation and provide context for future reference.
• Attach Source Documents: Always attach digital copies of invoices and receipts to their corresponding transactions within your software.
• Reconcile Regularly: Reconcile your bank accounts with your software's records frequently to catch discrepancies early.
• Back Up Your Data: Ensure your software provider offers robust data backup and recovery solutions.

By proactively addressing these areas, sole traders and landlords can effectively prepare for MTD ITSA and leverage the enhanced functionality now available through compliant software, turning a compliance obligation into an opportunity for better business management.
