Introduction to Making Tax Digital for Income Tax Self Assessment

The landscape of tax reporting in the UK is undergoing a significant transformation with the phased rollout of Making Tax Digital for Income Tax Self Assessment, commonly referred to as MTD ITSA. This initiative, spearheaded by HMRC, aims to modernise the tax system by making it easier for individuals to keep their tax records up to date and providing them with a near real-time view of their tax position. Starting from April 6, 2026, self-employed individuals and landlords whose combined income from these sources exceeds £50,000 will be mandated to comply with MTD ITSA rules.

This change represents a fundamental shift from the traditional annual Self Assessment tax return. Instead of a single yearly submission, affected taxpayers will be required to maintain digital records of their income and expenses using HMRC-recognised software. Furthermore, they will need to submit quarterly summaries of their financial data to HMRC, along with an End-of-Period Statement and a Final Declaration. The primary goal is to reduce common errors, streamline the tax process, and enhance transparency for taxpayers. Understanding these new software requirements is crucial for ensuring a smooth transition and maintaining compliance with HMRC regulations.

This comprehensive guide will delve into the specific software requirements for MTD ITSA, detailing what constitutes HMRC-recognised software, the intricacies of digital record keeping, the process for submitting quarterly updates, and the importance of End-of-Period Statements and Final Declarations. We will also cover eligibility thresholds, exemptions, potential penalties for non-compliance, and how platforms like AccountsOS are designed to assist sole traders and landlords in navigating these new obligations effectively.

What is Making Tax Digital for Income Tax Self Assessment?

Making Tax Digital for Income Tax Self Assessment (MTD ITSA) is a key part of the UK government's plan to make tax administration more effective, more efficient, and easier for taxpayers. It mandates that certain self-employed individuals and landlords use digital software to keep their business records and send updates to HMRC periodically throughout the tax year, rather than just once a year.

Who Does MTD ITSA Affect?

MTD ITSA primarily affects:

Self-employed individuals: Sole traders who run a business.
Landlords: Individuals who rent out property.

The obligation to join MTD ITSA is determined by a taxpayer's 'qualifying income'. This refers to the total gross income from all self-employment businesses and property businesses. It is important to note that this is combined income, not per business. If you have multiple self-employment ventures or multiple rental properties, the income from all these sources is added together to determine if you meet the threshold.

Key Dates and Thresholds for MTD ITSA

The rollout of MTD ITSA is phased, with initial implementation focusing on those with higher incomes. The thresholds are set to decrease in subsequent years, bringing more taxpayers into the MTD regime.

Tax Year	Combined Income Threshold	Applies To
2026/27	£50,000+	Sole Traders & Landlords
2027/28	£30,000+	Sole Traders & Landlords
2028/29 onwards	£20,000+	Sole Traders & Landlords

For example, if a sole trader has gross income of £35,000 from their business and also receives £20,000 in gross rental income from a property, their combined qualifying income is £55,000. This means they would fall above the £50,000 threshold and would be required to comply with MTD ITSA rules from April 2026. It is crucial for taxpayers to accurately assess their combined income to determine their MTD ITSA obligations.

Why is MTD for ITSA Being Introduced?

HMRC outlines several key objectives for the introduction of MTD ITSA:

Reducing errors: Digital record keeping and regular updates are expected to significantly reduce common errors in tax returns, such as transposition mistakes or miscalculations. HMRC estimates that over £8 billion per year is lost due to avoidable errors.
Modernising the tax system: Bringing the UK tax system into the 21st century, aligning it with other digitally advanced tax administrations globally.
Real-time financial overview: Providing taxpayers with a more current and comprehensive view of their tax position throughout the year, rather than a single, potentially overwhelming, annual calculation. This allows for better financial planning and budgeting.
Simplified interactions with HMRC: Making it easier for taxpayers to interact with HMRC digitally, reducing the need for paper-based submissions and phone calls for routine queries.

The transition to MTD ITSA is designed to create a more transparent, efficient, and user-friendly tax system for self-employed individuals and landlords.

What Are the Core MTD Software Requirements?

At the heart of MTD ITSA lies the mandatory use of HMRC-recognised software. This software must facilitate several key functions that are fundamental to the new digital tax reporting process. The requirements go beyond simply submitting figures; they dictate how records are kept and how information flows to HMRC.

HMRC-Recognised Software

The most crucial requirement is that the software used must be 'HMRC-recognised' or 'MTD-compatible'. This means the software has been tested and approved by HMRC to interact directly with their systems via an Application Programming Interface (API). It is not enough for software to simply produce the correct figures; it must be capable of sending and receiving data digitally in a specific format to and from HMRC.

What "HMRC-recognised" means: This designation ensures the software meets HMRC's technical specifications for MTD, allowing for secure and accurate digital submissions. Taxpayers should always check HMRC's official list of MTD-compatible software before making a choice. Using non-compliant software will result in penalties.

Digital Record Keeping

Under MTD ITSA, taxpayers are required to keep digital records of all their business income and expenses. This replaces the need for physical ledgers or paper-based accounting. The software must be able to store this information in a digital format, ensuring its integrity and accessibility.

Specific records that must be kept digitally include:

Income: The date, amount, and category of all income received.
Expenses: The date, amount, and category of all business expenses paid.
Capital expenditure: Details of assets purchased for the business.
Adjustments: Any adjustments made for private use of assets, stock valuations, or specific accounting adjustments.

The software should ideally automate as much of this process as possible, for instance, through bank feeds or receipt scanning, to minimise manual data entry and potential errors.

Quarterly Updates

Instead of a single annual tax return, MTD ITSA mandates the submission of quarterly summaries of income and expenses. These updates must be submitted to HMRC using the MTD-compatible software. Each update covers a three-month period within the tax year.

The quarterly updates provide HMRC with a more frequent snapshot of the taxpayer's financial activity. While these are summaries, they must be accurate and reflect the digital records maintained in the software. The deadlines for these submissions are fixed, regardless of your accounting period end date.

Accounting Period	Quarterly Update 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

Worked Example: Quarterly Update

Let's consider a sole trader, Sarah, whose business year aligns with the tax year (6 April to 5 April). For the first quarter, 6 April to 5 July 2026:

Total Income: £12,500
Total Expenses: £3,200 (including £1,000 for materials, £1,500 for rent, £700 for utilities)

Her MTD-compatible software will automatically pull these figures from her digital records. She will review the summary generated by the software, ensure its accuracy, and then authorise the submission to HMRC via the software's API. This submission must be completed by 5 August 2026. The software will then prepare for the next quarter's reporting. The quarterly updates are cumulative, meaning that each subsequent update will include the data from previous quarters in the same tax year, along with the new quarter's data, providing an ongoing summary.

End-of-Period Statement (EOPS)

After the final quarterly update for the tax year, taxpayers must submit an End-of-Period Statement (EOPS) for each business. The EOPS summarises the business's income and expenses for the entire tax year, making any necessary accounting adjustments.

These adjustments can include:

Capital allowances: Claims for tax relief on qualifying business assets.
Private use adjustments: Adjustments for business expenses that have a private element, such as a car used for both business and personal travel.
Stock valuation: Adjustments for the value of opening and closing stock.
Accruals and prepayments: Accounting adjustments to match income and expenses to the correct period.

The EOPS must be submitted by 31 January following the end of the tax year. For the tax year 2026/27, the EOPS would be due by 31 January 2028. The MTD software should assist in identifying and applying these adjustments, often with guidance or automated calculations.

Final Declaration

The Final Declaration replaces the traditional Self Assessment tax return. It consolidates all sources of income, not just self-employment and property income, but also employment income, pension income, savings income, and any other taxable income. It also includes personal allowances, reliefs, and any other claims that affect the taxpayer's overall tax liability.

The Final Declaration calculates the individual's total income tax and National Insurance contributions for the tax year. This must also be submitted through MTD-compatible software. The deadline for the Final Declaration is 31 January following the end of the tax year, aligning with the EOPS deadline. This is the final step in the MTD ITSA process for a given tax year, leading to the final calculation of tax owed or refund due.

Bridging Software for Spreadsheets

While HMRC encourages the use of fully integrated accounting software, they recognise that some businesses may prefer to continue using spreadsheets for their digital record keeping. In such cases, taxpayers can use 'bridging software'. Bridging software is a specific type of MTD-compatible software that connects a spreadsheet to HMRC's MTD systems.

This software allows you to:

Maintain your digital records in a spreadsheet.
Extract the required summary data from your spreadsheet.
Transmit this data directly to HMRC in an MTD-compliant format.

It essentially acts as a digital bridge, taking the data from your spreadsheet and sending it to HMRC's API. However, it is crucial that the spreadsheet itself constitutes 'digital records' and is not merely a summary of paper records. The raw transaction data must originate digitally or be digitised upon receipt.

Considerations for Bridging Software: While bridging software offers flexibility, it requires careful management. The risk of errors is higher with manual data transfer or spreadsheet manipulation compared to fully integrated solutions. Taxpayers must ensure their spreadsheets are robust, accurate, and consistently updated to meet digital record keeping standards.

How to Choose HMRC-Recognised MTD Software

Selecting the right MTD-compliant software is a critical decision for sole traders and landlords. The market offers a variety of solutions, each with different features, pricing, and user experiences. Making an informed choice can significantly ease the transition to MTD ITSA and ensure ongoing compliance.

Key Features to Look For in MTD Software

When evaluating MTD-compatible software, consider the following essential features:

HMRC Recognition: Verify that the software is officially listed on HMRC's website as MTD-compatible for Income Tax. This is non-negotiable.
Digital Record Keeping: The software must allow you to digitally record all relevant income and expense transactions. This includes categorisation, dates, and amounts.
Automated Bank Feeds: Integration with your business bank accounts to automatically import transactions significantly reduces manual data entry and improves accuracy.
Expense Tracking and Categorisation: Features like receipt scanning, OCR (Optical Character Recognition) for automated data extraction from receipts, and predefined expense categories are invaluable.
Quarterly Update Generation and Submission: The software should automatically compile the necessary data for quarterly updates and allow direct submission to HMRC via API.
End-of-Period Statement (EOPS) Support: Functionality to assist with year-end adjustments, such as capital allowances or private use, and to generate and submit the EOPS.
Final Declaration Integration: While some software focuses solely on business income, comprehensive solutions may help consolidate all income sources for the Final Declaration.
Real-Time Tax Estimates: A valuable feature that provides an ongoing estimate of your tax liability based on your recorded income and expenses, helping with financial planning.
Reporting Capabilities: Clear dashboards and reports that provide insights into your financial performance and tax position.
User-Friendliness: An intuitive interface and ease of use are crucial, especially for those new to accounting software.
Customer Support: Access to reliable customer support for troubleshooting and guidance.
Security: Robust data encryption and security measures to protect your sensitive financial information.

Integration with Other Tools and Scalability

Consider whether the software integrates with other tools you might use, such as CRM systems, e-commerce platforms, or payroll software. Seamless integration can streamline your entire business operation, reducing duplicate data entry and improving efficiency.

Scalability is another important factor. If your business is growing, you want software that can grow with you, offering advanced features as your needs evolve. Choosing a solution that can handle increasing transaction volumes and potentially more complex accounting requirements in the future can save you time and effort in the long run.

Who is Exempt from Making Tax Digital for ITSA?

While MTD ITSA is becoming mandatory for a significant number of sole traders and landlords, certain individuals may be exempt from the requirements. It is crucial to understand these exemptions, as non-compliance can lead to penalties.

Specific Exemption Categories

HMRC outlines specific criteria for exemption:

Religious Beliefs: Individuals whose religious beliefs are incompatible with the use of electronic communications or digital records.
Disability: Individuals who are unable to use digital tools due to age, disability, or living in a remote area with unreliable internet access. This is assessed on a case-by-case basis.
Insolvency: Individuals who are subject to an insolvency procedure, such as bankruptcy.
Non-resident landlords: Certain non-resident landlords may have different reporting requirements, but generally, if they meet the income threshold, they are expected to comply.
Income below threshold: Naturally, if your combined qualifying income from self-employment and property business falls below the MTD ITSA threshold for the relevant tax year, you are not required to join MTD. However, you can opt in voluntarily.

To apply for an exemption, individuals typically need to contact HMRC directly to explain their circumstances. HMRC will then assess the application and inform the individual of their decision. It is important to obtain official confirmation of any exemption.

Penalties for Non-Compliance

HMRC has established a penalty regime for non-compliance with MTD ITSA rules. These penalties are designed to encourage timely and accurate submissions. They can be incurred for various reasons, including late submissions, failure to keep digital records, and inaccuracies.

Scenario	Penalty
Late Quarterly Update	Points-based system, leading to £200 penalty for every 4 points
Late End-of-Period Statement (EOPS)	Initial £100, then daily penalties
Late Final Declaration	Initial £100, then daily penalties
Failure to Keep Digital Records	Up to £3000 for each failure
Inaccurate Records/Submission	Penalty based on behaviour, from 0% to 100% of extra tax due

Interest on late payments: In addition to penalties for late submissions or non-compliance, HMRC will also charge interest on any tax that is paid late. This interest accrues from the payment due date until the tax is settled, adding significantly to the overall cost of non-compliance. The current interest rate is typically the Bank of England base rate plus 2.5%, subject to change.

It is advisable to stay organised and use MTD-compliant software to avoid these penalties and ensure a smooth tax reporting process. Proactive management of digital records and timely submissions are key to maintaining compliance.

Your Journey to MTD ITSA Compliance: A Step-by-Step Guide

Navigating the transition to MTD ITSA can seem daunting, but by following a structured approach, sole traders and landlords can ensure a smooth and compliant journey. Here is a step-by-step guide to help you prepare and meet your MTD obligations.

Step 1: Check Your Income Threshold. The first crucial step is to determine if you are mandated to join MTD ITSA. Calculate your total gross income from all self-employment businesses and property businesses for the relevant tax year. Remember, for April 2026, the threshold is £50,000. If your combined income is above this, you must comply. Keep in mind the thresholds reduce to £30,000 in 2027 and £20,000 in 2028.
Step 2: Choose MTD-Compliant Software. Select an HMRC-recognised software solution that meets your business needs. This software will be the cornerstone of your MTD ITSA compliance. Look for features like automated bank feeds, expense categorisation, real-time tax estimates, and direct submission capabilities to HMRC. Ensure it is listed on HMRC's official MTD software providers list.
Step 3: Register for MTD ITSA. Once you have chosen your software, you will need to register for MTD ITSA with HMRC. This is usually done through your chosen MTD software or via your agent. You cannot register until you are ready to start using MTD-compatible software. Ensure you have your Government Gateway user ID and password ready.
Step 4: Keep Digital Records. Begin maintaining all your business income and expenses digitally using your chosen software from the start of your first MTD tax year. This means recording every transaction, categorising it correctly, and ensuring all relevant details are captured. Integrate your bank accounts and utilise features like receipt capture to automate this process as much as possible.
Step 5: Submit Quarterly Updates. At the end of each quarter, your software will generate a summary of your income and expenses. Review this summary carefully, make any necessary minor adjustments within the software, and then submit it to HMRC before the deadline. There are four quarterly updates per tax year, with fixed deadlines (5 August, 5 November, 5 February, 5 May).
Step 6: Submit End-of-Period Statement (EOPS). After your final quarterly update, prepare and submit an EOPS for each of your businesses. This statement includes any year-end accounting adjustments, such as capital allowances, private use adjustments, or stock valuations. Your software should guide you through this process. The deadline for the EOPS is 31 January following the end of the tax year.
Step 7: Submit Final Declaration. The Final Declaration consolidates all your income sources, including those not covered by MTD ITSA (e.g., employment income, pensions), and applies any personal allowances and reliefs. This comprehensive submission calculates your total tax liability for the year. It is also due by 31 January following the end of the tax year.
Step 8: Pay Your Tax Bill. Based on your Final Declaration, HMRC will issue your final tax bill. The payment deadline for this is typically 31 January following the end of the tax year, with a second payment on account due on 31 July. Ensure you make payments on time to avoid interest and penalties. Your MTD software may provide reminders and estimated payment amounts.

Practical Tips for a Smooth MTD Transition

Transitioning to MTD ITSA can be a significant change for many sole traders and landlords. Adopting best practices can help ensure a smooth and stress-free experience, allowing you to focus on your business rather than worrying about tax compliance.

Start Early and Plan Ahead

Do not wait until the last minute to prepare for MTD ITSA. Begin researching and choosing your MTD-compatible software well in advance of your mandatory start date. This will give you ample time to:

Familiarise yourself with the software: Learn its features, how to record transactions, and how to generate reports.
Clean up existing records: If you currently have paper records or disorganised digital files, take the time to digitise and organise them.
Test the process: Many software providers offer free trials. Use this opportunity to practice recording transactions and submitting mock quarterly updates.

Early preparation reduces stress and helps you identify any potential issues before they become critical.

Train Yourself or Your Staff

If you have employees who handle financial records, ensure they are adequately trained on the new MTD software and the requirements for digital record keeping. Even if you manage your own accounts, invest time in understanding how to use the software effectively. Many software providers offer tutorials, webinars, and help documentation.

Proper training minimises errors, improves efficiency, and ensures that everyone involved understands their role in maintaining MTD compliance.

Regular Reconciliation and Review

Under MTD ITSA, regular reconciliation of your bank accounts with your digital records is more important than ever. This practice ensures that all transactions are captured and accurately categorised.

Monthly checks: Reconcile your bank statements with your software records at least monthly to catch discrepancies early.
Review before submission: Before submitting each quarterly update, take the time to thoroughly review the generated summary. Check for any missing transactions, incorrect categorisations, or duplicate entries.

Proactive review reduces the likelihood of submitting inaccurate information to HMRC, which could lead to penalties.

Seek Professional Advice When Needed

While MTD-compatible software simplifies many aspects of tax reporting, complex financial situations may still benefit from professional advice. If you have multiple businesses, unusual income streams, significant capital gains, or are unsure about specific tax treatments or adjustments, consider consulting an accountant or tax advisor.

Many accountants are already well-versed in MTD and can provide invaluable guidance, help with software setup, or even manage your MTD submissions on your behalf, often using their own MTD-compatible agent software.

Common Pitfalls to Avoid

Being aware of common mistakes can help you steer clear of them:

Ignoring Deadlines: The quarterly update deadlines are fixed. Missing them will result in penalties. Set reminders and adhere strictly to the schedule.
Incomplete Record Keeping: Merely having software is not enough; you must consistently record all relevant transactions. Missing expenses means paying more tax than necessary.
Using Non-Compliant Software: Ensure your chosen software is on HMRC's approved list. Using unrecognised software will lead to non-compliance.
Waiting Until the Last Minute: Attempting to input months of data just before a deadline is a recipe for errors and stress. Keep your records updated regularly, ideally weekly or monthly.
Confusing Business and Personal Finances: Continue to keep business and personal finances separate. This simplifies digital record keeping and avoids confusion during tax calculations.

Frequently asked questions

When do I need to start MTD for Income Tax?

You must start MTD for Income Tax Self Assessment from April 6, 2026, if your combined gross income from self-employment and property business is £50,000 or more. The threshold reduces to £30,000 from April 2027, bringing more taxpayers into the scheme.

What counts as 'combined income' for the MTD threshold?

Combined income refers to the total gross income from all your self-employment businesses and all your UK and overseas property businesses. It is the sum of these incomes, not the profit, that determines if you meet the MTD ITSA threshold.

Can I still use a spreadsheet for MTD ITSA?

Yes, you can use a spreadsheet, but it must be combined with 'bridging software'. This software allows your spreadsheet to connect to HMRC's systems and submit MTD-compliant updates. Your spreadsheet must also meet digital record keeping requirements.

What if I have multiple businesses?

If you have multiple self-employment or property businesses, you will need to keep digital records for each business separately within your MTD-compatible software. You will then submit a single End-of-Period Statement (EOPS) for each individual business, and a single Final Declaration encompassing all your income.

Do I need an accountant for MTD ITSA?

While MTD-compatible software simplifies the process, you do not strictly need an accountant. However, if your tax affairs are complex or you prefer professional assistance, an accountant can manage your MTD submissions and provide expert advice. They will also use MTD-compatible software.

How often do I need to update my records?

You must keep your records digitally and submit quarterly updates to HMRC. While the updates are quarterly, it is best practice to update your records regularly, ideally weekly or monthly, to ensure accuracy and avoid a last-minute rush.

What if my income drops below the threshold?

If your combined income from self-employment and property business drops below the MTD ITSA threshold in a subsequent tax year, you may be able to opt out of MTD. You should check HMRC's guidance on opting out and ensure you meet the criteria.

Is VAT MTD the same as Income Tax MTD?

No, while both are part of the broader Making Tax Digital initiative, they are separate. VAT MTD applies to VAT-registered businesses for their VAT returns, while MTD ITSA applies to sole traders and landlords for their Income Tax Self Assessment. They have different thresholds, reporting periods, and specific requirements.
