Making Tax Digital (MTD) is a government initiative introduced to transform the UK’s tax system, making it more efficient, transparent, and easier to manage for both taxpayers and professionals like accountants, bookkeepers, and tax advisers. MTD was part of the Finance Act 2017 and became mandatory for VAT-registered businesses with a turnover of £85,000 or more from 1st April 2019.

But what exactly does MTD mean, and how will it affect accountants, bookkeepers, and tax advisers? This guide will explain the key aspects of MTD, its implications for tax professionals, and the steps you need to take to get ready.

Making Tax Digital for Income Tax: What It Means for Your Clients?

The Making Tax Digital (MTD) initiative aims to streamline the tax process, benefiting both taxpayers and accountants by reducing complexities and enhancing accuracy.​

Under the traditional system, individuals often need a comprehensive understanding of tax rates, brackets, deductible expenses, allowances, and various taxable benefits, which can lead to errors and incorrect tax payments. MTD addresses these challenges by requiring businesses and individuals to keep digital records and use compatible software to submit updates to HMRC every quarter, bringing the tax system closer to real-time reporting. ​

By adopting MTD-compatible software, taxpayers can simplify the filing process. These digital tools can connect directly to bank accounts, automatically pulling in data, saving time, and reducing the risk of errors. This integration also assists with business forecasting and cash flow management, enabling informed, real-time financial decisions.

To comply with MTD, taxpayers need to:​

  • Update their HMRC-compatible software quarterly
    This ensures that all financial data is current and accurately reflects income and expenses.
  • Incorporate any one-time income
    Add any additional income that isn’t part of regular earnings to maintain accurate records.
  • Submit the final confirmation form
    After reviewing all information, submit the form to HMRC to complete the tax filing process.

By following these steps, taxpayers can ensure accurate filings, avoid penalties, and gain a clearer understanding of their financial position throughout the year. This proactive approach not only simplifies tax compliance but also enhances overall financial management.

Is this really that easy?

Yes and no.

Yes, because Making Tax Digital (MTD) has simplified tax calculation and filing for general taxpayers. However, it also introduces additional responsibilities, as taxpayers must maintain digital records of income and expenses and submit updates to HMRC multiple times a year.

To streamline this process and minimise hassle, taxpayers can appoint certified accountants or tax advisers to manage their tax affairs on their behalf. This service is quick and straightforward, taking only a few minutes.

Regardless of the approach, taxpayers will ensure they pay the correct amount of tax each year.

That said, there’s no need to worry. As tax advisers and accountants, our role is now more crucial than ever. With real-time tax filing comes real-time tax planning—helping individuals and businesses stay compliant while optimising their tax position.

When Does Making Tax Digital Start?

MTD is being implemented in phases, and key deadlines are approaching for different types of taxpayers:

Phase Date Requirement
MTD for VAT (Phase 1) April 2019 Businesses with turnover > £85,000 must use MTD-compatible software to file VAT returns.
MTD for VAT (Phase 2) April 2022 All VAT-registered businesses, regardless of turnover, must comply with MTD.
MTD for Income Tax Self-Assessment (ITSA) April 2026 Self-employed individuals and landlords with income > £50,000 must use MTD for ITSA.
MTD for ITSA (Phase 2) April 2027 Self-employed individuals and landlords with income > £30,000 must use MTD.
MTD for ITSA (Phase 3) April 2028 Self-employed individuals and landlords with income > £20,000 must use MTD.

Who is Exempt from MTD?

Currently, all taxpayers, except for VAT-registered businesses, are exempt from the Making Tax Digital (MTD) initiative. However, starting in April 2026, individuals with a qualifying income of £50,000 or more in the 2024–25 tax year will be required to file taxes through MTD. This requirement will extend to those earning £30,000 or more in the 2025–26 tax year, effective from April 2027 and to those earning £20,000 or more in the 2025–26 tax year, effective from April 2028.

Note:

  • You could be already exempt from MTD for VAT if your business is subject to insolvency procedure and you have cancelled your VAT registration.
  • You can apply for exemptions from MTD for VAT if using computers is not reasonable or practical because of your age, health condition, disability or religious grounds. To apply, write or call to HMRC.

  • Quarterly Updates to HMRC
    Add any additional income that isn’t part of regular earnings to maintain accurate records.
  • Transition Assistance

    Many businesses transitioning to MTD will need help with setting up new systems or migrating from paper-based systems to digital platforms.

Impact of MTD on Tax Advisers

MTD will affect the role of tax advisers, shifting their focus from regulatory compliance to proactive planning and advisory:

  • Proactive Tax Planning
    Tax advisers will need to provide more strategic advice, helping clients optimise
  • Review Submissions
    Tax advisers will play a role in reviewing quarterly submissions to ensure that tax filings are accurate, addressing any discrepancies before they are sent to HMRC.
  • Handling Complex Cases

    While MTD software will handle basic tax calculations, complex cases (such as foreign investments or trusts) will still require expert tax advice.

Digital VAT: What Tax Advisers Need to Know

As of April 2022, all VAT-registered businesses are automatically enrolled in Making Tax Digital (MTD). Tax advisers no longer need to manually sign-up clients, but it remains essential to ensure that clients are correctly registered for VAT. Advisers must also ensure that VAT records are accurately maintained and submitted quarterly using HMRC-compatible software in compliance with MTD regulations.
