Essential Guide to Understanding Making Tax Digital for Self Assessment Changes and Requirements

Tax filing in the UK is entering a new era with the introduction of Making Tax Digital (MTD) for Self Assessment. This change aims to simplify tax reporting and improve accuracy by moving from traditional paper-based or manual processes to digital submissions. If you file a Self Assessment tax return, understanding what is changing, who it affects, and what you need to do is crucial to avoid penalties and stay compliant.

What is Making Tax Digital for Self Assessment?

Making Tax Digital is a government initiative designed to modernize the tax system by requiring taxpayers to keep digital records and submit tax information using compatible software. For Self Assessment taxpayers, this means moving away from the traditional annual paper tax return to a system where income and expenses are reported digitally in quarterly updates, with a final declaration at the end of the tax year.

The goal is to reduce errors, make tax filing easier, and provide real-time information to HM Revenue & Customs (HMRC). This system also helps taxpayers keep better track of their tax liabilities throughout the year.

Who Needs to Comply with MTD for Self Assessment?

MTD for Self Assessment applies to individuals and businesses with income over a certain threshold. Specifically:

• Self-employed individuals or sole traders with annual business income above £10,000

• Landlords with rental income above £10,000

• Partners in partnerships with income above £10,000

  
  

If your total income from self-employment or property rental exceeds £10,000 in a tax year, you must comply with MTD rules. This includes keeping digital records and submitting quarterly updates using HMRC-approved software.

Those with income below this threshold are currently exempt but may choose to adopt MTD voluntarily.

What Changes with MTD for Self Assessment?

The biggest change is how you report your income and expenses to HMRC. Instead of submitting one annual tax return, you will:

• Keep digital records of your income and expenses using compatible software

• Submit quarterly updates of your income and expenses to HMRC

• Make a final declaration after the end of the tax year to confirm your tax liability

  
  

This means you need to track your finances regularly and use software that can connect directly to HMRC’s systems. Paper records or spreadsheets alone will no longer meet the requirements.

How to Prepare for MTD for Self Assessment

Preparing for MTD involves several practical steps:

Choose Compatible Software

You must use software that is approved by HMRC for MTD submissions. Many accounting packages now offer MTD-compatible versions. Examples include:

• QuickBooks

• Xero

• FreeAgent

• Sage

  
  

Some software providers offer free or low-cost options for small businesses and landlords.

Set Up Digital Record Keeping

Start keeping your income and expenses digitally. This means entering all transactions into your software regularly. Avoid relying on paper receipts or manual spreadsheets.

Understand Quarterly Reporting

You will submit updates every three months, reporting income and expenses for that period. These updates help HMRC track your tax position in real time. The deadlines for these updates are:

• Quarter 1: April to June – due by 31 July

• Quarter 2: July to September – due by 31 October

• Quarter 3: October to December – due by 31 January

• Quarter 4: January to March – due by 30 April

  
  

Keep Supporting Documents

Although you submit digital summaries, you must keep all original receipts and invoices for at least 5 years in case HMRC requests them.

Common Questions About MTD for Self Assessment

What if I miss a quarterly update?

Missing deadlines can lead to penalties. HMRC expects timely submissions, so set reminders and plan your bookkeeping accordingly.

Can I still file a paper tax return?

No. Once you are required to comply with MTD for Self Assessment, paper returns are no longer accepted.

What if I have multiple sources of income?

You must include all relevant income in your digital records and quarterly updates, including self-employment, rental income, and other taxable income.

Is MTD only for income tax?

Currently, MTD for Self Assessment focuses on income tax from self-employment and property rental. Other taxes like VAT have separate MTD rules.

Benefits of Adopting MTD Early

While MTD may seem like extra work, it offers benefits:

• Better financial control through regular updates

• Reduced risk of errors with automated calculations

• Faster tax refunds due to quicker processing

• Clearer view of tax liabilities throughout the year

  
  

Many taxpayers find that digital record keeping simplifies their overall accounting and reduces stress at tax time.

What to Do Next

If you are affected by Making Tax Digital for Self Assessment, start by:

• Checking if your income exceeds the £10,000 threshold

• Researching and selecting HMRC-approved software

• Setting up digital record keeping immediately

• Planning your quarterly submissions to avoid penalties

  
  

HMRC provides guidance and support for taxpayers transitioning to MTD. You can also consult an accountant or tax advisor for personalized help.
