Full Guide to Making Tax Digital for Accountants, Bookkeepers & Tax Advisers

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.

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