# Best HMRC-Approved Accounting Software for UK MTD Income Tax (ITSA) in 2026?

Last updated: 5 September 2026

To comply with HMRC's Making Tax Digital for Income Tax Self Assessment (MTD ITSA) from April 2026, UK businesses must use HMRC-approved accounting software that facilitates digital record-keeping, quarterly updates, and year-end filings. Key players like Xero, Sage, and QuickBooks offer live ITSA support; AccountsOS is building full ITSA support ahead of April 2026 and is already live for VAT MTD.

The landscape of tax compliance for self-employed individuals and landlords in the UK is undergoing a significant transformation with HMRC's Making Tax Digital for Income Tax Self Assessment, or MTD ITSA. Effective from April 2026 for those with qualifying income over £50,000, and April 2027 for those earning over £30,000, this mandate requires businesses to abandon traditional manual record-keeping in favour of digital methods. The core principle is that all relevant income and expenses must be recorded digitally and submitted to HMRC through MTD-compatible software in quarterly updates, followed by an End of Period Statement and a Final Declaration.

This shift is not merely a procedural change, it's a fundamental overhaul designed to reduce errors, provide businesses with a clearer real-time view of their tax position, and streamline interactions with HMRC. The critical implication for businesses is the mandatory adoption of HMRC-approved accounting software. This comprehensive guide delves into the specifics of MTD ITSA, explores the leading HMRC-approved software options, explains the role of bridging software, and provides a strategic roadmap for businesses to ensure they are fully prepared and compliant well before the deadlines. Understanding and implementing the right software solution now can save significant time, stress, and potential penalties in the future.

Key dates:

| Event | Date |
|---|---|
| MTD ITSA Mandate (Income £50,000+) | April 2026 |
| MTD ITSA Mandate (Income £30,000+) | April 2027 |
| Digital Record Keeping Required | Ongoing from Mandate Date |

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

Making Tax Digital for Income Tax Self Assessment, commonly referred to as MTD ITSA, represents a pivotal shift in how self-employed individuals and landlords manage their tax affairs in the United Kingdom. This initiative, spearheaded by HMRC, aims to modernise the tax system by making it entirely digital, with the ultimate goal of simplifying tax reporting, reducing errors, and providing taxpayers with a more current understanding of their tax liabilities.

### Who Does MTD ITSA Affect?

MTD ITSA will initially apply to:

- Self-employed individuals with a qualifying business income exceeding £50,000, becoming mandatory from the accounting period starting on or after 6 April 2026.
- Landlords with a qualifying property income exceeding £50,000, also becoming mandatory from the accounting period starting on or after 6 April 2026.
- Self-employed individuals and landlords with a qualifying business or property income exceeding £30,000, becoming mandatory from the accounting period starting on or after 6 April 2027.

It is crucial to note that "qualifying income" refers to gross income, not profit. If an individual has both self-employment income and property income, these are combined to determine if they meet the threshold. For example, if a self-employed person earns £30,000 from their trade and £25,000 from property, their combined qualifying income is £55,000, meaning they would fall into the April 2026 mandate. Limited companies are not currently included in MTD ITSA, as they fall under Corporation Tax.

### Core Principles of MTD ITSA

The MTD ITSA framework is built upon four fundamental pillars:

1. **Digital Record Keeping:** Taxpayers must keep digital records of all their business income and expenses. This means all transactions must be recorded and stored electronically using MTD-compatible software. Manual input, such as typing data from paper receipts into a spreadsheet, is explicitly prohibited unless the spreadsheet is digitally linked to bridging software.
2. **Quarterly Updates:** Instead of a single annual tax return, businesses will be required to submit summary updates of their income and expenses to HMRC at least once every three months. These updates must be submitted digitally via MTD-approved software. The deadlines for these quarterly submissions are typically one month after the end of each quarter.
3. **End of Period Statement (EOPS):** After the final quarterly update for the tax year, an End of Period Statement must be submitted. This statement allows for any necessary accounting adjustments, such as calculating capital allowances, accruals, or prepayments, that were not included in the quarterly summaries. It finalises the taxable profit or loss for each business source.
4. **Final Declaration:** This replaces the traditional Self Assessment tax return. After the EOPS has been submitted for all income sources, the Final Declaration brings together all income, including non-business income, and allows for any reliefs or allowances to be claimed. This declares the final tax position and determines the tax liability for the year.

These requirements mark a significant departure from previous practices, demanding a proactive and continuous approach to tax management. The emphasis is on real-time data flow and digital interaction with HMRC, making robust accounting software an indispensable tool for compliance.

## Why is HMRC Mandating Commercial Software for MTD ITSA?

HMRC's decision to mandate the use of commercial software for MTD ITSA is rooted in several strategic objectives aimed at transforming the UK's tax system. The overarching goal is to create a more efficient, accurate, and transparent tax environment for both taxpayers and the tax authority.

### Reducing the Tax Gap and Errors

One of HMRC's primary motivations for MTD is to reduce the "tax gap": the difference between the amount of tax theoretically due and the amount actually collected. A significant portion of this gap is attributed to avoidable errors, particularly among self-employed individuals and small businesses. Manual record-keeping and annual lump-sum reporting often lead to:

- **Transcription errors:** Mistakes when transferring figures from paper records to digital formats or tax returns.
- **Missing deductions:** Forgetting to claim legitimate expenses over a long accounting period.
- **Incorrect categorisation:** Misclassifying income or expenses due to a lack of clear guidance or tools.
- **Last-minute rush:** Errors occurring when compiling an entire year's worth of data just before the annual deadline.

By mandating digital record-keeping and quarterly updates through software, HMRC anticipates that businesses will maintain more accurate and up-to-date financial records. Software can automate calculations, flag potential errors, and provide a structured framework for categorising transactions, thereby significantly reducing the incidence of human error.

### Simplifying Compliance for Taxpayers

While the initial transition to MTD ITSA may seem daunting, HMRC believes that in the long run, it will simplify tax compliance for businesses. Key benefits include:

- **Real-time financial visibility:** Quarterly updates encourage businesses to keep their records current, offering a clearer, more immediate understanding of their financial performance and tax position throughout the year, rather than just at year-end.
- **Spreading the workload:** Instead of a single, intensive annual tax return, the workload is spread across four quarterly submissions, making the process more manageable.
- **Automated calculations:** MTD-compatible software can automatically calculate income, expenses, and even provisional tax liabilities, reducing the mental burden on taxpayers.
- **Easier interaction with HMRC:** The digital platform allows for seamless submission of data, reducing the need for manual forms and postal communications.

### The Ban on Manual Data Entry and Digital Links

A cornerstone of the MTD mandate is the prohibition of manual data entry for submitting updates. This means that once data has been recorded digitally, it must flow through a "digital link" to the MTD-compatible software and then directly to HMRC. This eliminates the possibility of errors introduced by re-keying figures.

For businesses that wish to continue using spreadsheets for some aspects of their record-keeping, this means that those spreadsheets must be "digitally linked" to HMRC-approved bridging software. This bridging software acts as a conduit, taking the summarised digital data from the spreadsheet and submitting it to HMRC in the MTD-compliant format. Crucially, any transfer of data from one digital tool to another must also be digital, meaning copy-pasting or manually typing figures from a spreadsheet into the bridging software is not permitted. This strict requirement underscores the necessity of integrated digital solutions.

### Modernising the Tax System

Ultimately, MTD ITSA is part of HMRC's broader strategy to modernise the entire UK tax system, bringing it in line with other advanced economies that have already adopted digital tax reporting. This modernisation aims to create a more resilient, efficient, and future-proof tax infrastructure capable of handling the complexities of a digital economy. For businesses, embracing MTD ITSA through appropriate software is not just about compliance, it's about future-proofing their financial management practices.

## Key Requirements for MTD ITSA Compliant Software

Choosing the right software for MTD ITSA compliance is paramount. Not all accounting software is created equal, and specific features are essential to meet HMRC's stringent requirements. An HMRC-approved software solution must demonstrate several core capabilities to ensure businesses can seamlessly transition to the new digital tax regime.

- Digital record-keeping capabilities for all transactions
- Automated submission of quarterly income and expense updates to HMRC
- Ability to submit End of Period Statements (EOPS)
- Support for submitting the Final Declaration
- Secure API integration with HMRC's MTD platform
- Compatibility with bridging software for spreadsheet users
- Real-time overview of tax position and liabilities
- Audit trail for all submitted data

### Detailed Breakdown of Essential Features

Let us elaborate on the critical functionalities an MTD ITSA compliant software must offer:

### 1. Digital Record Keeping for All Transactions

The foundation of MTD ITSA is the requirement for digital records. This means that for every business transaction, whether income or expense, the following details must be recorded digitally:

- Date of transaction
- Amount of the transaction
- Category of income or expense (e.g., sales, purchases, travel, utilities)
- Type of transaction (e.g., invoice, receipt, bank transfer)

The software must be capable of capturing this data accurately and storing it in a way that is easily retrievable and auditable. This typically involves direct bank feeds, receipt scanning, and automated categorisation features. Manual data entry into the software is generally acceptable for individual transactions, but the overall record-keeping process must be digital.

### 2. Automated Submission of Quarterly Income and Expense Updates

This is perhaps the most significant change from the traditional Self Assessment system. MTD-compliant software must be able to:

- Aggregate the digital records for each quarter.
- Generate a summary of total income and total expenses for that period.
- Submit this summary directly to HMRC via a secure API link.

The software should also provide clear visibility of submission deadlines and confirmation of successful submissions. This automation significantly reduces the administrative burden and minimises the risk of missing deadlines.

### 3. Ability to Submit End of Period Statements (EOPS)

At the end of the tax year, after the final quarterly update, an EOPS is required for each business source. The software must facilitate the creation and submission of this statement, allowing for:

- Adjustments for accounting principles (e.g., accruals, prepayments, depreciation).
- Claiming capital allowances.
- Finalising the taxable profit or loss for the business.

This ensures that the final figures reported to HMRC accurately reflect the business's tax position after all necessary accounting adjustments have been made.

### 4. Support for Submitting the Final Declaration

The Final Declaration replaces the annual Self Assessment tax return. MTD software, or potentially a combination of software and professional advice, must enable the submission of this final statement, which:

- Consolidates all business income (from EOPS) and other income sources (e.g., employment, pensions, savings interest).
- Applies any personal allowances, reliefs, or tax credits.
- Calculates the final tax liability for the entire tax year.

While some comprehensive accounting software can handle this, many businesses may still rely on their accountant to review and submit the Final Declaration, especially for complex tax situations.

### 5. Secure API Integration with HMRC's MTD Platform

All submissions under MTD ITSA must be made directly through HMRC's Application Programming Interface (API). This means the software must have a robust and secure connection to HMRC's systems, ensuring data integrity and confidentiality. Any software claiming MTD compliance must be officially recognised by HMRC as having this capability.

### 6. Compatibility with Bridging Software for Spreadsheet Users

For those who prefer to maintain some records in spreadsheets, the chosen software ecosystem must include or integrate with "bridging software." This software acts as an intermediary, taking the summarised digital data from spreadsheets and submitting it to HMRC via the MTD API. Critically, the link between the spreadsheet and the bridging software must be digital, prohibiting manual copy-pasting or re-keying. This ensures the continuous digital journey of the data.

### 7. Real-time Overview of Tax Position and Liabilities

A significant advantage of MTD is the ability to have a more current view of one's tax position. Effective MTD software should provide dashboards or reports that:

- Estimate current tax liabilities based on recorded income and expenses.
- Track quarterly submissions and upcoming deadlines.
- Help with tax planning throughout the year.

### 8. Robust Audit Trail

In the event of an HMRC enquiry, businesses must be able to demonstrate that their records are accurate and that submissions were made correctly. MTD software should automatically create an audit trail, detailing:

- When transactions were recorded.
- How they were categorised.
- When quarterly updates, EOPS, and Final Declarations were submitted.

This comprehensive record-keeping capability is vital for peace of mind and compliance assurance. When evaluating software, ensuring these features are present and robust is the first step towards a smooth MTD ITSA transition.

## What if I use Spreadsheets? Bridging Software Explained

Many self-employed individuals and landlords have historically relied on spreadsheets for their record-keeping due to their flexibility and cost-effectiveness. While MTD ITSA mandates digital record-keeping and submissions via approved software, HMRC does provide an option for those who wish to continue using spreadsheets: bridging software.

### How Bridging Software Works

Bridging software acts as a vital link between your digital spreadsheet records and HMRC's MTD platform. Its primary function is to:

- **Extract Data:** It pulls the summarised income and expense data directly from your MTD-compliant spreadsheet.
- **Convert Format:** It converts this data into the specific digital format required by HMRC's MTD API.
- **Submit to HMRC:** It securely transmits the formatted data for your quarterly updates, EOPS, and Final Declarations to HMRC.

Crucially, the "digital link" requirement means that data transfer from your spreadsheet to the bridging software must be automated. Copying and pasting figures, or manually re-typing them, is not permitted under MTD rules. This typically involves formulas within the spreadsheet that link to specific cells, or functionality within the bridging software to import the data directly.

### Limitations and Challenges of Bridging Software

While bridging software offers a pathway to MTD compliance for spreadsheet users, it comes with certain limitations and challenges compared to a full accounting software package:

- **Maintaining Digital Links:** Ensuring robust and error-free digital links between your spreadsheet and bridging software can be complex, especially for those less familiar with advanced spreadsheet functions.
- **Increased Manual Effort:** You are still responsible for manually categorising and entering every transaction into your spreadsheet. This lacks the automation benefits of full accounting software, such as bank feeds and AI categorisation.
- **Higher Risk of Errors:** The more manual steps involved, the greater the potential for human error in data entry or formula mistakes within the spreadsheet.
- **Limited Functionality:** Spreadsheets lack integrated features like invoicing, expense management tools, real-time reporting dashboards, or direct links to payment gateways. Bridging software only handles submission, not the underlying bookkeeping.
- **Audit Trail:** While your spreadsheet is a digital record, maintaining a clear, auditable trail of changes and submissions can be more challenging than with dedicated accounting software.
- **Scalability:** As your business grows, managing complex transactions and multiple income streams through spreadsheets can quickly become cumbersome and inefficient.

### Example Workflow with Bridging Software

Consider a self-employed graphic designer using a spreadsheet:

1. **Record Transactions:** The designer manually enters all invoices issued and business expenses (e.g., software subscriptions, travel costs) into a pre-formatted MTD-compliant spreadsheet. Each entry includes date, amount, and category.
2. **Quarterly Summarisation:** At the end of each quarter, the spreadsheet uses formulas to automatically sum up total income and expenses for that period.
3. **Digital Link to Bridging Software:** The designer then uses bridging software. This software is configured to "read" the summary figures directly from specific cells in their spreadsheet.
4. **Submission:** The bridging software then securely transmits these quarterly summary figures to HMRC via the MTD API.
5. **Year-End Adjustments:** At year-end, the designer makes any necessary accounting adjustments (e.g., capital allowances for a new laptop) directly in their spreadsheet, and the bridging software is used again to submit the End of Period Statement and eventually the Final Declaration.

While feasible, this method still requires a significant investment of time and attention to detail in managing the spreadsheet itself. For many, the integrated features and automation of full accounting software offer a more streamlined and less error-prone path to MTD ITSA compliance.

## Choosing the Right Software for Your Business

Selecting the ideal accounting software for MTD ITSA compliance is a critical decision that can impact your business's efficiency, accuracy, and overall tax experience. There is no one-size-fits-all solution, so it's essential to evaluate your specific needs and circumstances.

### Factors to Consider

When comparing different software options, consider the following key factors:

- **Business Size and Complexity:**
  - **Sole Traders/Freelancers:** May prefer simpler, more affordable solutions like FreeAgent or AccountsOS that focus on core income and expense tracking.
  - **Growing Businesses/Landlords with Multiple Properties:** Might benefit from more robust platforms like Xero, Sage, or QuickBooks which offer advanced features such as project tracking, multi-currency support, or more detailed reporting.
- **Industry Specific Needs:**
  - Do you need inventory management, time tracking, or specific integrations relevant to your sector? Some software may be better equipped for certain industries.
- **Budget:**
  - Software subscriptions range from less than £10 to over £50 per month. Consider the long-term cost and ensure it aligns with your financial projections. Remember, the investment in good software can often save money through efficiency and reduced penalties.
- **Ease of Use and User Interface:**
  - How intuitive is the software? Can you easily navigate its features, or will it require significant training? A user-friendly interface reduces frustration and increases adoption. Many providers offer free trials to test this.
- **Automation Capabilities:**
  - Look for features like automated bank feeds, receipt scanning with OCR (Optical Character Recognition), and AI-powered categorisation. These significantly reduce manual data entry and save time. AccountsOS, for instance, excels in this area.
- **Integration with Other Tools:**
  - Do you use CRM software, e-commerce platforms, payment gateways (e.g., Stripe, PayPal), or project management tools? Check if the accounting software integrates seamlessly with your existing tech stack.
- **Accountant's Preference:**
  - If you work with an accountant, ask for their recommendations. Many accountants specialise in certain software platforms, which can streamline collaboration and reduce costs for year-end reviews.
- **Customer Support and Resources:**
  - What kind of support is offered? Phone, email, live chat, knowledge base? Reliable support is crucial, especially during the initial setup and MTD transition.
- **Mobile Accessibility:**
  - If you're often on the go, a robust mobile app for tracking expenses and managing invoices can be invaluable.

## Preparing for MTD ITSA in 2026

The MTD ITSA mandate for businesses with income over £50,000 is just around the corner, taking effect from April 2026. For those with income over £30,000, the deadline is April 2027. Early preparation is crucial to ensure a smooth transition, avoid penalties, and leverage the benefits of digital tax reporting.

### Timeline and Key Dates

Understanding the timeline is the first step:

- **Before April 2026 (for £50k+ income):** Assess current systems, research and select MTD-compatible software, migrate historical data (if applicable), register for MTD ITSA (if joining the pilot), and begin training.
- **From April 2026:** Mandatory start for qualifying businesses with income over £50,000. Begin keeping digital records and submitting quarterly updates.
- **Before April 2027 (for £30k+ income):** Same preparation steps as above.
- **From April 2027:** Mandatory start for qualifying businesses with income over £30,000.

### Steps to Take Now

Proactive steps will significantly ease your transition:

1. **Assess Your Current Record-Keeping System:**
   - Are you currently using paper records, spreadsheets, or existing accounting software?
   - How digital are your current processes? Identify gaps in meeting MTD's digital record-keeping requirements.
   - Evaluate your income sources. Do you have self-employment income, property income, or both?
2. **Research and Choose MTD-Compatible Software:**
   - Refer to HMRC's list of approved software.
   - Utilise the comparison table and selection checklist provided earlier in this guide.
   - Take advantage of free trials to test software before committing.
3. **Migrate Existing Data:**
   - Once you've chosen software, plan for migrating any necessary historical data. Many software providers offer tools or services to assist with this.
   - Ensure data accuracy during migration to avoid issues later.
4. **Train Yourself and Your Staff:**
   - Familiarise yourself and any relevant staff with the new software and the MTD ITSA reporting processes.
   - Many software providers offer tutorials, webinars, and support documentation.
5. **Engage with Your Accountant:**
   - Your accountant is an invaluable resource. Discuss your MTD ITSA obligations and software choices with them.
   - They can help with software setup, training, and ensuring accurate quarterly submissions and year-end filings.
   - Many accountants are already MTD-ready and can guide you through the process.
6. **Consider Joining the MTD ITSA Pilot Scheme:**
   - HMRC offers a pilot scheme for MTD ITSA, allowing businesses to voluntarily join early.
   - This can be an excellent way to get familiar with the new system, identify potential issues, and receive support before it becomes mandatory.

### Common Pitfalls and How to Avoid Them

Being aware of common mistakes can help you navigate the transition more smoothly:

- **Late Adoption:** Delaying the switch to MTD-compatible software until the last minute can lead to rushed decisions, errors, and stress. Start early.
- **Data Migration Issues:** Incorrectly migrating historical data can cause discrepancies. Plan carefully and seek professional help if needed.
- **Incorrect Categorisation:** Misclassifying income or expenses can lead to inaccurate tax calculations. Ensure you understand HMRC's categorisation rules or use software with smart categorisation (like AccountsOS).
- **Lack of Training:** Insufficient understanding of the software or MTD processes can lead to errors and missed deadlines. Invest time in learning.
- **Not Understanding MTD Rules:** The rules surrounding digital links, quarterly updates, EOPS, and Final Declarations are specific. Read HMRC guidance or consult your accountant.
- **Ignoring Non-Compliance Penalties:** HMRC will implement a new points-based penalty system for MTD ITSA. Understanding these penalties can motivate timely compliance.

### Worked Example: Transitioning to MTD ITSA

Let us consider Sarah, a self-employed web designer with an annual income of £60,000, whose accounting period aligns with the tax year (April to March). She currently uses a basic spreadsheet.

1. **Current Situation (Pre-April 2026):** Sarah records her invoices and expenses in a spreadsheet. Annually, her accountant uses this spreadsheet data to prepare her Self Assessment tax return.
2. **Preparation (Late 2025 to Early 2026):**
   - Sarah learns about MTD ITSA and the April 2026 mandate for her income level.
   - She consults her accountant, who recommends AccountsOS for its automation and MTD features.
   - Sarah signs up for AccountsOS, connects her business bank account for automated feeds, and uses the receipt scanning feature for her expenses. She spends a few hours watching tutorials and familiarising herself with the system.
   - Her accountant helps her set up her opening balances and verifies her initial categorisation rules.
3. **First MTD ITSA Year (April 2026 to March 2027):**
   - **Quarter 1 (Apr-Jun 2026):** AccountsOS automatically imports bank transactions. Sarah reviews and confirms AI-categorised entries. By 5 August 2026, she uses her MTD software to review the summary and submit her first quarterly update to HMRC. (AccountsOS ITSA quarterly submission is in development ahead of April 2026.)
   - **Quarter 2 (Jul-Sep 2026):** Same process. By 5 November 2026, second quarterly update submitted.
   - **Quarter 3 (Oct-Dec 2026):** Same process. By 5 February 2027, third quarterly update submitted.
   - **Quarter 4 (Jan-Mar 2027):** Same process. By 5 May 2027, fourth quarterly update submitted.
   - **End of Period Statement (EOPS):** After her final quarterly update, her accountant reviews the AccountsOS data, makes any necessary year-end adjustments (e.g., capital allowances for a new laptop), and submits the EOPS for her web design business by 31 January 2028.
   - **Final Declaration:** Her accountant then compiles her web design income with any other income (e.g., savings interest) and submits the Final Declaration, also by 31 January 2028.

This example illustrates how a well-chosen software and early preparation can transform MTD ITSA from a daunting obligation into a streamlined, manageable process, offering greater financial clarity throughout the year.

## Penalties for Non-Compliance with MTD ITSA

HMRC is introducing a new points-based penalty system for MTD ITSA non-compliance, designed to be fairer and more proportionate than the previous system. However, businesses still face significant financial repercussions for failing to meet their MTD obligations.

### Late Submission Penalties (Points-Based System)

Instead of an immediate monetary penalty, taxpayers will accrue "penalty points" for late submissions.

- **One point for each late submission:** This applies to quarterly updates, EOPS, and the Final Declaration.
- **Penalty threshold:** Once a taxpayer reaches a certain number of points, a monetary penalty is issued.
- **Monetary penalty:** £200 for every threshold reached.
- **Points expiry:** Points expire after 24 months, provided all submissions for that period were made on time.
- **Thresholds:**
  - Annual submission frequency (e.g., for MTD ITSA Final Declaration): 2 points before penalty.
  - Quarterly submission frequency (e.g., for MTD ITSA Quarterly Updates): 4 points before penalty.

This system is designed to encourage consistent compliance, with penalties escalating for persistent late filers.

### Late Payment Penalties

Separate from submission penalties, late payment of tax will also incur charges:

- **First penalty:** If tax is unpaid 15 days after the due date, a penalty of 2% of the amount unpaid is charged.
- **Second penalty:** If tax is still unpaid 30 days after the due date, a further penalty of 2% of the amount unpaid is charged.
- **Ongoing penalties:** After 30 days, a daily penalty of 4% per year (annualised) is charged on the unpaid amount until it is paid.

These penalties can quickly accumulate, adding significantly to a business's tax burden.

### Penalties for Failure to Keep Digital Records

Beyond late submissions and payments, HMRC can also levy penalties for failing to meet the fundamental requirement of keeping digital records. If HMRC finds that records are not kept digitally, or that digital links are not maintained, a penalty may be issued. The range for such penalties is typically between £100 and £3000, depending on the severity and persistence of the failure.

### Interest on Unpaid Tax

In addition to penalties, HMRC charges interest on any tax paid late. The interest rate is typically the Bank of England base rate plus 2.5%. This interest is charged from the date the tax was due until the date it is paid in full. For substantial tax liabilities, this interest can add up quickly, further increasing the cost of non-compliance.

**Mitigation:** While penalties are strict, HMRC does consider reasonable excuses for non-compliance. However, simply forgetting or not understanding the rules is generally not accepted as a reasonable excuse. Proactive engagement with HMRC or your accountant is always advisable if you foresee difficulties in meeting deadlines.

## Frequently asked questions

### Who needs to comply with MTD ITSA?

MTD ITSA is mandatory for self-employed individuals and landlords with qualifying gross income over £50,000 from April 2026, and over £30,000 from April 2027. If you have both self-employment and property income, these are combined to determine if you meet the threshold.

### What are quarterly updates?

Quarterly updates are summary reports of your business income and expenses that you must submit to HMRC every three months using MTD-compatible software. These replace the traditional annual tax return for reporting business figures throughout the year.

### Can I still use an accountant for MTD ITSA?

Absolutely. Accountants play a crucial role in MTD ITSA. They can help you choose the right software, ensure your records are accurate, review your quarterly updates, prepare your End of Period Statements, and submit your Final Declaration to HMRC.

### What if my business income is below the MTD ITSA threshold?

If your qualifying gross income remains below the threshold (£50,000 from April 2026, £30,000 from April 2027), MTD ITSA is not mandatory for you. You can continue to file a traditional Self Assessment tax return, though you can opt in to MTD voluntarily.

### What is bridging software?

Bridging software is an HMRC-approved tool that allows you to extract summarised digital data from a spreadsheet and submit it to HMRC in an MTD-compliant format. It's a solution for those who want to continue using spreadsheets for record-keeping, but requires digital links between the spreadsheet and the software.

### When do I need to start preparing for MTD ITSA?

It is highly recommended to start preparing well in advance of your mandatory start date. For those affected in April 2026, you should be researching software, assessing your current systems, and planning your transition now to avoid last-minute stress and potential penalties.

### What happens if I miss an MTD ITSA deadline?

HMRC will implement a new points-based penalty system for late MTD ITSA submissions. You will accrue penalty points for each missed deadline, and once a certain threshold is reached, a monetary penalty of £200 will be issued. Late payments also incur separate penalties and interest.

### Is MTD ITSA mandatory for limited companies?

No, MTD ITSA is specifically for self-employed individuals and landlords. Limited companies are subject to Corporation Tax and currently have separate MTD requirements (MTD for Corporation Tax is planned for a later date, but no specific timeline has been set yet).
