Did you know that the way you complete your Self Assessment in the UK is changing, and a digital system is gradually replacing traditional yearly tax returns? Understanding these changes is important to stay compliant and avoid future complications.
Â
Making Tax Digital (MTD) introduces a new approach where income and expenses are recorded digitally and submitted to HMRC around the year instead of only once at the end. Many individuals and landlords are still unaware of how this shift affects their reporting obligations and daily record-keeping.
Â
TAJ Accountants help you throughout the Making Tax Digital process and guide you to prepare in advance. Furthermore, we maintain efficient records and ensure your self-assessment remains accurate and fully compliant with HMRC requirements.
What is Making Tax Digital for Self Assessment?
Making Tax Digital for Income Tax Self Assessment is a UK government initiative, developed by HM Revenue & Customs (HMRC), to modernise the tax system. It replaces paper-based reporting with digital for record-keeping and payment ease using HMRC- approved software. Â
Â
The main goal of MTD for ITSA is to help self-employed individuals and landlords report their income each quarter digitally to reduce the tax gap. It makes tax administration more effective, more efficient, and simpler for taxpayers through self-assessment.
Â
MTD for income tax Self Assessment is a great plan for HMRC. They led it for sole traders and landlords to get the following advantages:
Â
- Businesses can calculate, submit, and pay their accurate tax easily
- Reduce errors in paperwork because the software will connect with the tax administration directly.
- Assist business owners’ ongoing access to additional data. So they can make more informed financial decisions.Â
- Connect business internal systems with digital software. It helps to increase productivity.
Who Needs to Use MTD for Income Tax and When?
According to HMRC, you’ll need to use Making Tax Digital for ITSA, including:
Â
- You’re a sole trader or a landlord registered for Self AssessmentÂ
- If you get income from self-employment or property, or bothÂ
- And your qualifying income is more than the relevant threshold for the tax year
When you need to start using Making Tax Digital for Income Tax depends on your qualifying income within a tax year. If your qualifying income is over:
Â
- You earned £50,000 for the 2024 to 2025 tax year, which has already been effective from 6 April 2026
- If you earn £30,000 for the 2025 to 2026 tax year, you will need to use MTD from 6 April 2027
- £20,000 for the 2026 to 2027 tax year, you will need to use it from 6 April 2028
You don’t have to start Making Tax Digital for Income Tax until after you have submitted your first Self Assessment tax return. If you wish, you can volunteer to join MTD early.
Key Changes to Income Tax Self-Assessment
Making Tax Digital (MTD) has brought about a major change to the Self Assessment process, where, instead of the traditional once-a-year tax return, information is stored and reported digitally throughout the year. Taxpayers are now required to regularly record income and expenses using HMRC-approved software and send the information directly to HMRC through the system.
Â
These changes make the entire process more structured and real-time. Instead of having to calculate everything separately at the end of the year, the final declaration can be easily completed using previously saved information, which reduces errors and makes the entire tax process more efficient.
Quarterly Updates
A key part of Making Tax Digital is quarterly updates, where summary information on income and expenses is submitted to HMRC every three months. These updates are sent directly through the software, which usually includes basic information such as date, amount, and transaction type.
Â
Taxpayers update their financial situation 4 times in a tax year, which reduces the chance of missing any income or expense under this rule. Ensuring this update helps you prepare your tax return more easily, faster, and more accurately at the end of the year.Â
Digital Record Keeping
Making Tax Digital now makes it mandatory to keep records of income and expenses digitally. This requires regular recording of basic details of each transaction, such as the date, amount and type, using HMRC-approved software.
Â
This method keeps accounts up to date throughout the year, reducing the risk of missing information and eliminating the need to track everything down at the end of the year. Properly keeping digital records makes tax returns more accurate and simplifies the reporting process with HMRC.
Software Requirement
To complete the Income Tax Self Assessment under Making Tax Digital, it is mandatory to use HMRC-approved accounting software. This software is used to record income and expenses, send quarterly updates and complete the year-end declaration.
Â
The entire process is automated and simplified using software such as QuickBooks, Xero and FreshBooks. If necessary, bridging software can be used with spreadsheets, which connect existing data with HMRC.
Â
Using the right software makes accounting faster, more accurate and organised, which makes the entire tax process more efficient.
Final Declaration
Under Making Tax Digital, a final declaration is submitted at the end of the year, which confirms the final accounting for the entire tax year. Quarterly updates and digital records submitted throughout the year are combined at this stage and appear as part of the tax return.
Â
At this stage, you can correct or adjust the information if necessary, then you must submit a final declaration and complete the Self Assessment. However, the deadline remains the same—the return must be filed and tax paid by 31 January.
Â
Completing this step correctly ensures that the entire year’s accounting is accurate and compliance with HMRC is maintained.
Payment Deadlines
Even with the introduction of Making Tax Digital, the tax payment deadline remains unchanged. Self Assessment tax is due by 31 January each year, and payments on account are due by 31 January and 31 July if required.
Â
This payment schedule remains the same even after submitting quarterly updates, as these are used for reporting purposes only. It is therefore very important to pay your tax liability on time; otherwise, HMRC will impose penalties and interest.
Â
Knowing your calculations in advance makes it easier to plan your payments and avoid last-minute financial stress.
Change Penalty System
The point-based penalty system has been designed under Making Tax Digital to encourage voluntary compliance, reduce penalties for small mistakes, and make compliance serious. As a result, instead of an immediate direct financial penalty for one or two late returns, a certain number of points are accumulated.
Â
One point is counted for each quarterly missed update. When total points exceed a certain threshold (e.g., 4 points), a financial penalty is imposed. This system will mainly apply to the late submission of quarterly updates and a direct penalty will be applicable for late submission of tax returns.
Â
While this change creates some flexibility for taxpayers, it is still very important to meet the deadlines regularly.
