How Many Self Assessment Submissions Will UK Sole Traders Need to Make Under HMRC’s New MTD Rules?

A comprehensive guide for UK sole traders on Making Tax Digital for Income Tax Self Assessment (MTD ITSA). Understand the six annual submissions, deadlines, and how to comply.

Updated 23 September 202627 min read

Quick answer

Under HMRC’s Making Tax Digital for Income Tax Self Assessment (MTD ITSA) rules, affected UK sole traders will need to make six tax submissions annually: four quarterly income and expense updates, one End of Period Statement, and one Final Declaration. This significantly changes the traditional once-a-year Self Assessment process.

The landscape of tax reporting for sole traders in the UK is undergoing its most significant transformation in decades with the introduction of Making Tax Digital for Income Tax Self Assessment, commonly referred to as MTD ITSA. This new regime, spearheaded by HMRC, moves away from the familiar annual Self Assessment return towards a more frequent, digital reporting system. For many sole traders and landlords, this means a fundamental shift in how they manage their financial records and interact with the tax authority. No longer will a single annual submission suffice. Instead, a structured sequence of six submissions will become the norm each tax year, demanding greater consistency in digital record keeping and a more proactive approach to tax compliance. This comprehensive guide will detail each of these six submissions, outline who is affected, explain the new requirements, and provide practical advice for preparing for this pivotal change.

The core objective of MTD ITSA is to modernise the tax system, reduce errors, and provide taxpayers with a near real-time view of their tax position. While the transition may seem daunting, understanding the new framework is the first step towards seamless compliance. AccountsOS is committed to guiding sole traders through this evolution, offering tools and insights to simplify the process and ensure readiness for the new digital era of taxation.

Understanding Making Tax Digital for Income Tax Self Assessment (MTD ITSA)

Making Tax Digital (MTD) is a government initiative designed to make it easier for individuals and businesses to get their tax right and keep on top of their affairs. MTD for Income Tax Self Assessment (MTD ITSA) is the next phase of this programme, following the successful implementation of MTD for VAT. It represents a fundamental change from the traditional paper-based or annual online Self Assessment system to a fully digital, more frequent reporting method for income tax.

What is MTD ITSA?

At its core, MTD ITSA requires sole traders and landlords to keep digital records of their income and expenses and to submit these summaries to HMRC using MTD-compatible software. This moves away from a single annual declaration to a series of regular updates throughout the tax year, culminating in an annual End of Period Statement and a Final Declaration. The aim is to reduce common errors, provide taxpayers with a more current estimate of their tax liability, and streamline the interaction between taxpayers and HMRC.

Why is HMRC Introducing MTD ITSA?

HMRC's primary motivations for introducing MTD ITSA are multi-faceted:

  • Reduce the Tax Gap: HMRC estimates that a significant portion of the tax gap is due to errors made by individuals and small businesses, often stemming from poor record-keeping or mistakes in annual submissions. More frequent, digital reporting is expected to improve accuracy.
  • Modernise the Tax System: Aligning the UK tax system with digital advancements seen in other sectors, making it more efficient and user-friendly.
  • Provide Real-Time Information: Enabling taxpayers to see their tax position evolve throughout the year, helping them to plan for tax payments and avoid unexpected bills.
  • Simplify Compliance: While initially perceived as more complex, HMRC believes that digital tools will ultimately simplify the process for taxpayers by automating calculations and submissions.

Who is Affected and When?

MTD ITSA will be rolled out in phases based on an individual's total qualifying income from their businesses and/or property.

Type Income Threshold Starts
Sole Traders & Landlords £50,000 April 2026
Sole Traders & Landlords £30,000 April 2027
General Partnerships TBD Not before April 2027
  • From April 2026: Sole traders and landlords with a total qualifying income exceeding £50,000 per year. This income includes gross turnover from self-employment and gross property income, before expenses.
  • From April 2027: Sole traders and landlords with a total qualifying income exceeding £30,000 per year.
  • General Partnerships: MTD ITSA will be extended to general partnerships at a date yet to be confirmed, but not before April 2027.

It is crucial to note that these thresholds apply to individuals, not per business or property. If a sole trader has two businesses, and their combined gross income exceeds the threshold, they will be mandated for MTD ITSA. Similarly, if a landlord has multiple properties, their combined gross rental income determines their MTD ITSA obligation.

Exemptions from MTD ITSA

While MTD ITSA aims for broad coverage, certain individuals and entities are exempt:

  • Limited Companies: Corporation Tax is under a separate MTD programme, which is still in development.
  • Individuals with Income Below Thresholds: Those whose total qualifying income falls below the mandated thresholds are not currently required to join MTD ITSA, though they can opt-in voluntarily.
  • Specific Circumstances: Individuals who cannot comply with MTD due to reasons such as age, disability, remote location without internet access, or religious objections may apply for an exemption from HMRC.
  • Trusts, Estates, and some Partnerships: These entities are not currently within the scope of MTD ITSA.

What is 'Qualifying Income'? Qualifying income refers to the gross income from your self-employment or property business, before deducting any expenses. It is this gross figure that determines whether you meet the MTD ITSA threshold.

The Six Annual Submissions Explained

The heart of MTD ITSA lies in its new reporting structure, moving from a single annual Self Assessment form to a total of six mandatory submissions each tax year for affected sole traders and landlords. These six submissions are comprised of four quarterly updates, one End of Period Statement (EOPS), and one final declaration.

Submission Count Description
Quarterly Income and Expense Updates 4 Regular summaries of business income and expenses.
End of Period Statement (EOPS) 1 Annual declaration of business adjustments and claims.
Final Declaration (Self Assessment) 1 Consolidated personal tax return for all income.

1. Quarterly Income and Expense Updates (4 Submissions)

These are the most frequent submissions under MTD ITSA. Sole traders will need to send a summary of their business income and expenses to HMRC every three months.

  • Purpose: To provide HMRC with a regular snapshot of your business activity, allowing for a more up-to-date view of your tax position and helping to identify potential errors earlier. For the taxpayer, it offers a real-time estimate of tax liability.
  • What to Include: Each quarterly update will require a summary of your total income and total expenses for that period. You will not need to provide a detailed breakdown of every transaction, but rather categorised totals. For example, total sales, total cost of goods sold, total travel expenses, etc.
  • How to Submit: These updates must be submitted digitally via MTD-compatible software. This software will connect directly to HMRC's systems, transmitting the required data securely.
  • Deadlines: Quarterly updates are due one month after the end of each tax quarter. The standard tax year runs from 6 April to 5 April. The quarterly periods and their respective deadlines are:
Quarter End Date Submission Deadline
5 July 5 August
5 October 5 November
5 January 5 February
5 April 5 May

Sole traders can choose to align their accounting periods with calendar quarters or their own business quarters, provided these are consistent and HMRC-approved. This flexibility can help businesses integrate MTD reporting with their existing financial cycles.

Accuracy vs. Estimates in Quarterly Updates: While accuracy is always the goal, HMRC understands that quarterly updates might contain some estimates, especially for expenses that are not yet fully reconciled. These can be adjusted in subsequent quarterly updates or, more definitively, in the End of Period Statement. The key is to make reasonable efforts to be accurate.

2. End of Period Statement (EOPS) (1 Submission)

After the final quarterly update for a tax year, sole traders must submit an End of Period Statement for each business or property income source that falls under MTD ITSA.

  • Purpose: The EOPS allows for all necessary accounting adjustments and claims to be made for the entire tax year for a specific business or property. This is where you finalise your taxable profits or losses for that income source.
  • What to Include: This statement includes adjustments for things like:
    • Capital allowances.
    • Accruals and prepayments.
    • Stock valuations.
    • Private use adjustments, for example for vehicles or home office.
    • Adjustments for any errors or estimates made in the quarterly updates.
    • Tax reliefs and claims specific to your business.
  • How to Submit: Like quarterly updates, the EOPS must be submitted digitally via MTD-compatible software.
  • Deadlines: The EOPS is due on or before 31 January following the end of the tax year, 5 April. For example, for the tax year ending 5 April 2027, the EOPS would be due by 31 January 2028.

If you operate more than one sole trade business or have multiple property income streams that are MTD mandated, you will need to submit a separate EOPS for each. This ensures that the taxable profit for each distinct income source is accurately calculated before being consolidated.

3. Final Declaration (Self Assessment) (1 Submission)

The Final Declaration is the equivalent of the current Self Assessment tax return, but it is completed after all EOPS have been submitted. It consolidates all income sources, both MTD and non-MTD, to arrive at your total tax liability.

  • Purpose: To bring together all your income and deductions for the tax year, calculate your final Income Tax and National Insurance contributions, and declare any other relevant information to HMRC. This is your personal tax return.
  • What to Include:
    • The finalised profits or losses from all your MTD-mandated businesses and properties, taken from your EOPS.
    • Any other income not covered by MTD ITSA, such as employment income, PAYE, dividends, interest, foreign income, capital gains, or other property income below the MTD threshold.
    • Personal allowances and tax reliefs not covered in the EOPS.
    • Pension contributions.
    • Student loan repayments.
  • How to Submit: The Final Declaration is also submitted digitally through MTD-compatible software.
  • Deadlines: The Final Declaration is due on or before 31 January following the end of the tax year, 5 April. For example, for the tax year ending 5 April 2027, the Final Declaration would be due by 31 January 2028.

Unlike the EOPS, only one Final Declaration is submitted per individual, regardless of how many businesses or properties they operate. This single declaration acts as your ultimate personal tax return, encompassing all your taxable income for the year.

Key Requirements for MTD ITSA Compliance

Compliance with MTD ITSA extends beyond simply submitting the six annual forms. It requires a fundamental shift in how sole traders and landlords manage their financial records. The core principle is 'digital record keeping' and the use of 'MTD-compatible software'.

Digital Record Keeping: What Does It Mean?

Under MTD ITSA, traditional paper records, such as receipts in a shoebox, are no longer sufficient. You must keep digital records of all your business income and expenses. This doesn't necessarily mean every single transaction needs to be logged individually in a complex system, but the totals and categories must be digitally maintained.

  • What to Record Digitally:
    • The date of each transaction.
    • The amount of income or expense.
    • The category of income or expense, for example sales, travel, utilities.
    • The type of transaction, for example invoice, receipt.
    • Any other information required to complete your quarterly updates, EOPS, and Final Declaration.
  • Digital Format: Records must be kept in a digital format. This can be:
    • MTD-compatible software: Dedicated accounting software designed to meet MTD requirements.
    • Spreadsheets: While spreadsheets can be used to record data, they must be combined with 'bridging software' to transmit the information to HMRC. A spreadsheet alone is not MTD-compliant for submission.
    • Apps: Mobile applications that capture and categorize transactions digitally.

The concept of 'digital links' is also crucial. Once data has been entered into software, any transfer of that data to another piece of software, or for the purpose of submitting to HMRC, must be done digitally. Manual re-keying of data between systems is generally not permitted, as it introduces a risk of error.

Choosing MTD-Compatible Software

Selecting the right MTD-compatible software is perhaps the most critical step for sole traders preparing for MTD ITSA. The software must be able to:

  • Record and store your income and expense data digitally.
  • Categorize transactions according to HMRC's requirements.
  • Generate the four quarterly income and expense summaries.
  • Prepare and submit the End of Period Statement, EOPS.
  • Prepare and submit the Final Declaration, Self Assessment.
  • Communicate directly with HMRC's MTD systems via an Application Programming Interface, API.

Many existing accounting software providers are updating their platforms to be MTD ITSA compliant. AccountsOS is specifically designed to handle the complexities of MTD, offering an intuitive platform for digital record keeping, automated quarterly updates, and streamlined EOPS and Final Declarations.

What is 'Bridging Software'? Bridging software acts as a digital link between non-MTD-compatible software, like a basic spreadsheet, and HMRC's MTD systems. It takes data from the spreadsheet and converts it into the required digital format for submission. This allows businesses to continue using familiar tools for record keeping while still meeting MTD requirements.

Impact on Sole Traders and Landlords

The shift to MTD ITSA will bring about significant changes for sole traders and landlords. While the long-term benefits are touted to include fewer errors and better financial visibility, the initial transition will require adaptation.

Changes to Workflow and Accounting Practices

  • Increased Frequency of Reporting: The most obvious change is the move from one annual submission to six. This necessitates more regular attention to financial records.
  • Mandatory Digital Record Keeping: Paper receipts and manual ledgers will become obsolete for MTD-mandated businesses. Digital solutions will be essential.
  • Proactive Approach: Instead of a year-end scramble, MTD encourages a continuous, proactive approach to managing finances and understanding tax liabilities.
  • Categorization of Transactions: Businesses will need to ensure their income and expenses are correctly categorized throughout the year, rather than just at year-end.

Cash Flow Planning

One of the potential benefits for sole traders is improved cash flow planning. With quarterly updates providing a near real-time estimate of tax liability, businesses can:

  • Set Aside Funds: More accurately estimate their tax bill and set aside funds throughout the year, reducing the likelihood of a large, unexpected tax demand.
  • Identify Trends: Spot seasonal variations in income and expenses earlier, allowing for better financial forecasting.
  • Make Informed Decisions: Having up-to-date financial data can inform business decisions, such as pricing, investment, or expansion plans.

It is important to remember that MTD ITSA does not change the payment deadlines for Income Tax. Payments on account and final balancing payments will still be due on 31 January and 31 July. The quarterly submissions are for reporting, not for payment.

Administrative Burden vs. Benefits

The initial reaction to MTD ITSA often focuses on the increased administrative burden. However, HMRC and proponents of MTD highlight several benefits:

  • Reduced Errors: Digital systems can automate calculations and flag potential errors, leading to more accurate tax returns.
  • Less Stress: Spreading the tax reporting workload across the year can reduce the pressure of a single annual deadline.
  • Better Business Insight: Regular financial updates provide a clearer picture of business performance, aiding in decision-making.
  • Easier Interaction with HMRC: A more streamlined, digital platform for communication.

While there will be an initial learning curve and potentially some setup costs for new software, the long-term aim is to make tax compliance simpler and more integrated into daily business operations.

Seeking Professional Advice

Even with MTD-compatible software, many sole traders will find value in retaining the services of an accountant or tax advisor. They can:

  • Assist with Transition: Help set up MTD-compatible systems and ensure a smooth transition.
  • Ensure Compliance: Verify that records are being kept correctly and submissions are accurate.
  • Provide Tax Planning: Offer strategic advice on tax reliefs, allowances, and overall tax efficiency.
  • Handle Complexities: Manage more intricate tax situations, multiple income streams, or specific claims.
  • Deal with HMRC: Act as an agent to communicate with HMRC on your behalf.

Penalties for Non-Compliance with MTD ITSA

HMRC is introducing a new penalty regime specifically for MTD ITSA to encourage compliance with the more frequent reporting requirements. This system is designed to be fairer and more proportionate than the previous fixed penalties, initially focusing on points for late submissions rather than immediate fines.

The New Points-Based Penalty System

For late quarterly updates, HMRC will implement a points-based system.

  • Points Accumulation: For each missed quarterly submission deadline, you will receive a point.
  • Penalty Threshold: Once you accumulate a certain number of points within a specified period, for example 4 points within 12 months for annual filers, or 2 points within 12 months for quarterly filers, a financial penalty will be issued.
  • Penalty Amount: The financial penalty for reaching the threshold is expected to be £200.
  • Points Expiry: Points will expire after a period of compliant filing, meaning you can reset your points total by maintaining a clean record.

This system aims to give taxpayers a chance to correct their behaviour before facing financial penalties, reserving fines for persistent non-compliance.

Penalties for Other MTD ITSA Failures

In addition to the points-based system for quarterly updates, other types of non-compliance will attract penalties:

  • Late End of Period Statement, EOPS, or Final Declaration:
    • Initial Penalty: A fixed penalty of £100 if filed up to 3 months late.
    • Daily Penalties: An additional £10 per day for up to 90 days if still not filed after 3 months.
    • Further Penalties: After 6 months, a further penalty of 5% of the tax due or £300, whichever is greater. After 12 months, another 5% or £300.
  • Failure to Keep Digital Records: If you are mandated for MTD ITSA but fail to keep your records digitally, HMRC can impose a penalty of up to £3,000. This underscores the importance of using MTD-compatible software or bridging software from the outset.
  • Inaccurate Records or Submissions: Penalties for inaccuracies depend on whether the error was careless, deliberate but not concealed, or deliberate and concealed. These penalties are tax-geared, meaning they are a percentage of the additional tax due as a result of the inaccuracy, potentially ranging from 0%, if fully disclosed and reasonable care taken, up to 100% of the tax under-declared.
Scenario Penalty
Late Quarterly Update Points-based system, leading to financial penalties for repeated failures.
Late EOPS or Final Declaration Initial £100, then daily penalties, and further tax-geared penalties for significant delays.
Failure to keep digital records Up to £3000 for non-compliance with digital record-keeping requirements.
Inaccurate records or submissions Tax-geared penalties, potentially up to 100% of the tax under-declared, depending on behaviour.

Interest on Late Payments: It is crucial to remember that penalties for late submissions are separate from interest charged on late tax payments. If you pay your tax late, HMRC will charge interest from the due date until the date of payment, regardless of whether your return was filed on time.

Preparing for MTD ITSA: A Step-by-Step Guide

The transition to MTD ITSA requires proactive planning. Here's a practical guide for sole traders and landlords to ensure a smooth switch:

1. Assess Your Income and MTD Mandate Status

  • Calculate Gross Income: Determine your total gross income from all self-employment and property sources. This is the figure that dictates whether you fall above the £50,000, April 2026, or £30,000, April 2027, threshold.
  • Understand Your Start Date: Based on your income, identify when MTD ITSA will become mandatory for you.
  • Consider Voluntary Opt-in: Even if you are below the threshold, consider opting in early to familiarise yourself with the system and benefit from real-time tax visibility.

2. Choose Your MTD-Compatible Software

  • Research Options: Explore various MTD-compatible software solutions available on the market. HMRC provides a list of approved software.
  • Evaluate Features: Look for software that meets your specific business needs, offers intuitive digital record keeping, automates quarterly updates, and supports EOPS and Final Declarations. Consider ease of use, cost, and customer support.
  • AccountsOS: AccountsOS is designed to be fully MTD ITSA compliant, offering a streamlined approach to managing your finances and submitting to HMRC digitally.
  • Bridging Software: If you prefer to use spreadsheets, ensure you select reliable bridging software to facilitate digital submissions.

3. Implement Digital Record Keeping Early

  • Start Now: Do not wait until your MTD mandate date. Begin keeping digital records as soon as possible to get accustomed to the process.
  • Categorise Consistently: Establish a clear system for categorizing your income and expenses from the outset. This will make quarterly reporting much simpler.
  • Capture Data Regularly: Instead of batch-entering data once a month or quarter, aim to record transactions as they happen. Many MTD-compatible software solutions offer mobile apps for on-the-go data entry.

4. Understand Your Deadlines

  • Quarterly Dates: Familiarise yourself with the four quarterly reporting periods and their respective deadlines.
  • EOPS and Final Declaration: Remember these are due by 31 January following the tax year end.
  • Set Reminders: Utilise your chosen software's reminders or set up your own calendar alerts to avoid missing submissions and incurring penalties.

5. Consider Professional Help

  • Accountant Consultation: Discuss MTD ITSA with your accountant. They can provide tailored advice, assist with software setup, and manage your submissions.
  • Training: Many software providers and accounting firms offer training sessions to help you understand and implement MTD ITSA.

Proactive Planning is Key: The success of your MTD ITSA transition hinges on proactive planning and early adoption of digital record-keeping practices. By starting early, you can iron out any issues and ensure you are fully compliant when the mandate applies to you.

Voluntary Adoption and Alternatives

While MTD ITSA is becoming mandatory for certain income thresholds, sole traders and landlords not yet mandated still have options to consider regarding their tax reporting.

Benefits of Voluntary Early Adoption

Even if your income falls below the MTD ITSA threshold, there are compelling reasons to consider voluntarily adopting the new system:

  • Familiarisation: Get ahead of the curve and become familiar with the new digital processes before they become mandatory, avoiding a rushed transition.
  • Improved Financial Management: Benefit from real-time insights into your business's financial performance and estimated tax liability throughout the year.
  • Reduced Year-End Stress: Spreading the tax reporting workload over the year can significantly reduce the pressure associated with the annual Self Assessment deadline.
  • Fewer Errors: Digital record-keeping and automated submissions can help minimise human errors, leading to more accurate tax returns.
  • Future-Proofing: Prepare your business for the inevitable expansion of MTD to lower income thresholds in the future.

Considering Incorporation: Going Limited

One alternative mentioned in some source material is for sole traders to consider incorporating their business into a limited company. This is a significant decision with broader implications than just MTD ITSA.

  • MTD for Corporation Tax: While MTD ITSA applies to sole traders and landlords, limited companies are subject to Corporation Tax. MTD for Corporation Tax is also planned but is currently in a much earlier stage of development, with no firm mandatory start dates announced. This means that by becoming a limited company, you would temporarily defer the immediate MTD reporting requirements.
  • Legal and Financial Implications: Incorporating means your business becomes a separate legal entity. This brings benefits such as limited liability, potential tax efficiencies, for example Corporation Tax rates, dividend tax, and a more professional image. However, it also introduces more administrative duties, such as filing annual accounts with Companies House, more complex payroll, and additional compliance costs.
  • Professional Advice: The decision to incorporate should not be taken solely to avoid MTD ITSA. It requires careful consideration of your business structure, growth plans, and financial circumstances, ideally with advice from an accountant or business advisor.

For many sole traders, the benefits of remaining a sole trader, combined with the right MTD-compatible software, will outweigh the complexities of incorporation. The key is to choose the path that best suits your business and personal financial goals.

Worked Examples of MTD ITSA Submissions

To illustrate how the six annual submissions work in practice, let's consider a hypothetical sole trader, Sarah, who runs a graphic design business. Her accounting period aligns with the tax year, 6 April to 5 April.

Example 1: Quarterly Update Submission

Sarah's first tax quarter runs from 6 April to 5 July. By 5 August, she needs to submit her first quarterly update.

Sarah's Q1 (6 April to 5 July) Figures:

Item Amount
Total Income (Sales) £12,500
Office Supplies £300
Software Subscriptions £150
Travel Expenses £120
Marketing Costs £200
Total Expenses £770

Sarah uses AccountsOS. The software automatically pulls these categorised totals from her digital records. With a click, she submits these summary figures to HMRC by 5 August. The software also provides an estimated tax liability based on these figures, helping her to budget.

Example 2: End of Period Statement (EOPS)

After Sarah has submitted her four quarterly updates for the tax year ending 5 April 2027, she needs to prepare her EOPS for her graphic design business by 31 January 2028.

Sarah's EOPS Adjustments for Tax Year 2026/27:

Item Amount
Total Income (from 4 Quarterly Updates) £50,000
Total Expenses (from 4 Quarterly Updates) £5,500
Capital Allowances Claimed (New Laptop) -£1,200
Private Use Adjustment (Home Office) +£300
Final Taxable Profit for Business £43,600

In her EOPS, Sarah makes adjustments that couldn't be fully accounted for in the quarterly updates, such as claiming capital allowances for a new laptop purchased and adjusting for the private use portion of her home office expenses. AccountsOS guides her through these adjustments to calculate her final taxable profit for the business.

Example 3: Final Declaration (Self Assessment)

Once Sarah has submitted her EOPS for her graphic design business, she then completes her single Final Declaration by 31 January 2028.

Sarah's Final Declaration for Tax Year 2026/27:

Item Amount
Taxable Profit (Graphic Design Business) £43,600
Rental Income (Property, non-MTD mandated) £5,000
Bank Interest Received £200
Personal Allowance -£12,570
Pension Contributions -£2,000
Total Taxable Income for Self Assessment £34,230

Here, Sarah consolidates her finalised business profit from her EOPS with other income sources like property income, which is below the MTD threshold and therefore reported annually, and bank interest. She then applies her personal allowance and pension contributions to arrive at her total taxable income, upon which her final Income Tax and National Insurance liability will be calculated. AccountsOS facilitates this consolidation, calculating the final tax due and preparing the declaration for submission.

Conclusion

Making Tax Digital for Income Tax Self Assessment marks a significant evolution in tax reporting for UK sole traders and landlords. The move from a single annual submission to a total of six regular digital reports, comprising four quarterly updates, one End of Period Statement, and one Final Declaration, necessitates a proactive and digital approach to financial management. While the transition demands adaptation, the underlying goal is to simplify tax compliance, reduce errors, and provide taxpayers with greater visibility over their tax affairs throughout the year.

Understanding the new requirements, embracing MTD-compatible software like AccountsOS, and establishing robust digital record-keeping practices are crucial steps for ensuring a smooth transition and avoiding penalties. By preparing effectively, sole traders can transform this regulatory change into an opportunity for improved financial insight and more efficient business operations.

Frequently asked questions

Who is affected by MTD for Income Tax?

Sole traders and landlords with qualifying business or property income above the mandated thresholds (£50,000 from April 2026, £30,000 from April 2027) will be required to follow MTD ITSA rules. This applies to individuals, not limited companies.

What is digital record keeping under MTD ITSA?

Digital record keeping means maintaining your business income and expenses using MTD-compatible software, or spreadsheets combined with 'bridging software' to digitally submit information to HMRC. Manual paper records are no longer sufficient.

Can I use spreadsheets for MTD ITSA submissions?

Yes, you can use spreadsheets to record your transactions, but they must be linked to 'bridging software' that can digitally transmit the required data to HMRC. The spreadsheet itself cannot be directly submitted.

What if I have multiple income sources, like two sole trades?

If you have multiple sole trader businesses or property income streams that fall under MTD, you will need to submit separate quarterly updates and End of Period Statements for each business. However, a single Final Declaration will consolidate all your income sources, including non-MTD income.

What happens if I miss a quarterly update deadline?

HMRC will implement a new penalty system for MTD ITSA. This will involve a points-based system where accumulating points for late submissions will eventually trigger financial penalties. Early and consistent compliance is key to avoiding these.

Is MTD ITSA voluntary for businesses below the income thresholds?

Yes, businesses and landlords with income below the mandated thresholds can voluntarily opt into MTD ITSA. This can be beneficial for those who want to get ahead, streamline their accounting, and benefit from real-time tax insights.

How does MTD ITSA affect my tax payment deadlines?

MTD ITSA primarily changes the reporting process, not the payment deadlines. Payments on account and final balancing payments for Income Tax will still be due on 31 January and 31 July, as per the current Self Assessment rules.

Do I still need an accountant if I use MTD-compatible software?

While MTD-compatible software simplifies record-keeping and submissions, many sole traders will still benefit significantly from an accountant's expertise for tax planning, advice on complex claims, reviewing submissions, and ensuring overall financial health and compliance.
