What is Making Tax Digital for Sole Traders?

Making Tax Digital (MTD) is a UK government initiative that aims to transform the way tax is managed and reported. For sole traders, MTD means transitioning from paper-based records to digital systems for managing income tax. Instead of filing a single annual tax return, sole traders will be required to submit their tax information quarterly via compatible software, making the process timelier and more accurate.

Key Features:

Digital Tax Records: Sole traders will be required to maintain their financial records digitally, capturing income, expenses, and other relevant data automatically through accounting software.

Quarterly Submissions: Instead of annual tax returns, sole traders must submit updates to HMRC every quarter, reporting earnings and tax information in real time.

Real-Time Reporting: The new system allows for more accurate and up-to-date reporting, reducing errors and providing both the taxpayer and HMRC with a clearer view of tax obligations throughout the year.

Why it Matters:

MTD simplifies the tax process by eliminating the need for manual record-keeping, reducing the chances of human error, and ensuring tax compliance is up-to-date and accurate. This shift to digital also makes it easier for sole traders to stay on top of their finances, avoiding any last-minute rushes to file tax returns.

By streamlining the process, MTD helps reduce administrative burdens and penalties associated with late or incorrect filings. Ultimately, MTD ensures more efficient, transparent, and accurate reporting, which benefits both the taxpayer and HMRC.

Do Making Tax Digital (MTD) for income tax applies to sole traders?

MTD applies to self-employed individuals, sole traders, and certain businesses that meet specific criteria, such as annual turnover and the type of income they receive.

Types of Income: Sole traders with income from self-employment or property must report their earnings through an MTD-compatible software, breaking down their income and expenses digitally for quarterly updates.

Capital Gains: Profits from the sale of assets, such as property (excluding rental income) or investments, are also excluded.

Are Sole Traders Exempt from MTD for Income Tax?

Certain sole traders may be exempt from Making Tax Digital (MTD) for Income Tax. Generally, those with low turnover or income from certain types of sources may not need to comply with the new digital reporting requirements. Some common exemptions include:

Sole traders with turnover below £20,000: If your business income is below the £20,000 threshold, you are not required to comply with MTD even after April 2028 unless the government reduces the threshold criteria.

Certain types of income: Even if you're a sole trader with minimal income and a significant portion of your total income comes from pensions, interest, dividends, or capital gains, which do not count towards the qualifying income for MTD, you may be exempt from MTD requirements.

Age or disability-related exemptions: Sole traders with certain conditions, like age, health issues, or lack of reliable internet access that make it difficult to use digital tools, may also be exempt from MTD compliance.

How to Claim an Exemption:

If you believe you are eligible for an exemption from MTD, you need to:

  1. Check Eligibility: Review the criteria provided by HMRC to ensure you qualify for an exemption. The HMRC Website provides detailed information on who can apply for an exemption.

  1. Apply Through HMRC: To apply for an exemption, you must contact HMRC with your National Insurance number, your reason for exclusion, and other relevant details. While HMRC typically responds within 28 days, it's important to prepare for MTD in case your exemption isn't approved. If your circumstances change, you must inform HMRC.

  1. Keep Records: Even if you are exempt, it’s important to maintain clear records of your income and business activities, as HMRC may request documentation to support your exemption claim.

What are the compliance requirements for sole traders under MTD for income tax?

There are three key requirements under MTD i.e. Using compatible software, maintaining digital records and making the tax submissions.

Use MTD Compatible Software

MTD-compatible software is essential for meeting the compliance requirements:

  • The software must allow you to digitally record income and expenses, generate invoices, and automatically track your business finances.

  • It must be able to send quarterly updates and final year-end summaries to HMRC without the need for manual input.

  • MTD-compatible software helps automate and simplify the compliance process, reducing human error and ensuring that all submissions meet the necessary requirements set by HMRC.

Digital Record-Keeping

Under Making Tax Digital for Income Tax, sole traders must maintain digital records for all business-related transactions. This includes:

  • Receipts: Keeping digital copies of receipts for expenses and income.

  • Invoices: Storing invoices issued to clients or customers in a digital format.

  • Financial Statements: Maintaining digital records of your financial statements, such as profit and loss, balance sheets, and other key documents.

These records must be accurate, up-to-date, and stored digitally to ensure smooth quarterly updates and end-of-year tax submissions.

Tax Submissions

Sole traders will be required to submit their income tax details digitally, following a quarterly reporting system:

  • Quarterly Updates: Every quarter, you must submit updates to HMRC showing your income, expenses, and estimated tax liability. This replaces the traditional annual tax return. The default schedule for MTD ITSA updates is based on the tax year, running from 6 April to 5 April. 

 

Alternatively, you can apply to use standard calendar quarters. This option aligns with the financial year for many businesses. 

 

  • End-of-Year Submissions: At the end of the tax year, you will submit a final summary to HMRC. This confirms your earnings and ensures that any discrepancies from the quarterly updates are corrected.  Both quarterly updates and the final end-of-year submission must be done electronically using MTD-compatible software.

What MTD-compatible software do sole traders need for income tax compliance?

To comply with Making Tax Digital (MTD) for Income Tax, sole traders must use HMRC-approved software that enables digital record-keeping and facilitates quarterly updates and end-of-year submissions. This transition is mandatory for those with qualifying income, starting from April 2026.

When selecting MTD-compatible software, consider the following features:

  • Ease of Use: User-friendly interfaces that simplify the transition to digital record-keeping.

  • Automation: Automated categorisation of income and expenses to reduce manual data entry.

  • HMRC Integration: Direct submission capabilities for quarterly updates and end-of-year declarations.

  • Multi-Income Support: Ability to manage various income streams, including self-employment and property income.

  • Cost: Free options are available but assess whether premium features justify the cost based on your business needs.

What Should I Do if I Qualify for MTD?

Once you confirm that you qualify for Making Tax Digital (MTD), you need to undertake the below steps:

Register for MTD

The first step is to register with HMRC.

  • Visit the HMRC website to create your account or sign in if you already have one.

  • You will need to register for MTD for Income Tax and link your business details to your HMRC account.

  • After registering, HMRC will send you an MTD reference number that confirms your enrolment in the system. This will allow you to start submitting digital updates for your tax information.

Set Up Digital Record-Keeping

Setting up an MTD-compatible software system is crucial for complying with MTD requirements.

  • Choose a software solution that integrates with HMRC (such as RentalBux).

  • Input your business income, expenses, and relevant financial data into the software.

  • The system should automatically categorise your income and expenses, generate invoices, and keep digital records that meet HMRC standards.

  • Ensure that your software also allows you to maintain and update records quarterly to avoid missing any deadlines.

Submit Quarterly Updates

Once your digital records are set up, you will need to submit quarterly updates to HMRC.

  • The software will generate these updates automatically, but you will need to review them to ensure all information is correct before submission.

  • Each quarter, submit your updates on your business income, expenses, and tax estimates to HMRC via the MTD-compatible software.

  • Ensure your quarterly submissions are error-free by double-checking income figures and deductions. This will help avoid penalties and ensure that your tax obligations are accurate and timely.

Compliance under MTD

Submit Your Final Declaration:

After submitting all four quarterly updates for the tax year, you will need to make a Final Declaration.

• Final declaration confirms your total income for the year across all sources, including self-employment, property, and any other income streams outside the scope of MTD.

• You can make final adjustments, add any reliefs or allowances, and ensure your figures are accurate before submitting.

• The submission and payment deadline remains the same as Self-Assessment, 31 January following the end of the tax year.

What Are the Costs of Compliance with MTD for Sole Traders?

Sole traders need to incur software costs, additional costs for accountants and tax agents and some hidden costs of learning the system and processes. They are explained in detail as under:

Software Costs

The primary cost of complying with Making Tax Digital (MTD) is the software used for digital record-keeping and submitting updates to HMRC. The costs for MTD-compatible software can vary depending on the platform and the features offered:

  • Free Software: Some solutions for landlords and self-employed sole traders, offer free versions for basic MTD compliance.

  • Paid Software: More comprehensive software options typically charge monthly or annual subscription fees, ranging from £10 to £30 per month or more, depending on the complexity of your business needs. These platforms usually offer additional features such as advanced reporting, multi-income tracking, and integration with bank accounts.

Additional Costs

Beyond software, there may be additional costs for professional support:

  • Accountants or Tax Agents: If you prefer not to manage your tax filings on your own, you might need to hire an accountant or tax agent to help with your MTD compliance. The costs of hiring an accountant can vary widely, typically ranging from £100 to £300 per hour or more, depending on the complexity of your business and the services required. Some accountants may offer fixed fees for MTD compliance.

  • Specialists for Complex Cases: If you have complex tax situations, such as multiple income streams, international income, or VAT obligations, you might require specialist advice, which could incur additional costs.

Hidden Costs

While the upfront and recurring costs are easier to identify, there are also indirect costs associated with transitioning to MTD compliance:

  • Time Spent Learning the System: If you're new to digital tools, there will be an investment of time in learning how to use the software. This could take several hours or days, especially if you’re managing your own records and submissions.

  • Updating Internal Processes: You may need to adjust your internal record-keeping practices to align with MTD. This could include training employees, creating new workflows, and ensuring your business operations are compatible with the new digital requirements.

  • Ongoing Time Commitments: Even with automated software, you’ll need to allocate time each quarter to review and submit your updates to HMRC. This regular commitment might also result in additional business hours dedicated to tax compliance.

Did you know:

HMRC estimates that individuals within the £30,000 to £50,000 income bracket may face an average transitional cost of £350, with an additional annual cost of £110. Those earning above £50,000 could incur an average transitional cost of £285, along with an average annual additional cost of £115.

What Are the Penalties for Non-Compliance with MTD?

Failing to comply with Making Tax Digital (MTD) can result in fines and penalties from HMRC. These can include penalties for late submissions, inaccurate or incomplete records, and failure to use MTD-compatible software.

The penalty system for MTD for Income Tax Self-Assessment (MTD ITSA) now operates on a points-based system. Instead of automatic fines for late submissions, sole traders accumulate points for each late submission of their quarterly updates or final tax return.

  • For every missed deadline, points are added to your record.

  • Once a certain number of points is reached, a financial penalty will be applied.

For quarterly updates sole traders will receive one point for each late quarterly update submission whereas for the final annual submission (end-of-year tax return) if submitted late, an additional point is added.

The penalty system operates within rolling 24-month windows for the points-based system. This means that penalties are not automatically applied in the first year of compliance, but accumulate over time, allowing traders to have a clean slate if they maintain compliance going forward.

Common Mistakes Sole Trader Makes that Attracts Penalties

Some of the common reasons why sole traders fail to comply with MTD include:

Late Submissions

Missing quarterly deadlines for submitting income and tax updates.

Incomplete or Incorrect Records

Failing to keep accurate and complete digital records, leading to inaccurate submissions.

Avoiding Penalties

To avoid penalties, sole traders should:

  • Stay on top of deadlines: Ensure quarterly updates are submitted on time to avoid late submission fees.

  • Use MTD-Compatible Software: Adopt approved software that automates record-keeping and submissions, reducing the risk of errors.

  • Double-check your records: Review income, expenses, and tax estimates before submitting to ensure accuracy and completeness.
