What Is Making Tax Digital and Who Needs to Register?

Making Tax Digital (MTD) represents HMRC's shift towards digital tax collection. Instead of paper records, businesses must maintain digital records using government-approved software solutions.

Since April 2019, VAT-registered businesses with a turnover above £85,000 have been required to follow MTD for VAT. From April 2022, this rule expanded to include all VAT-registered businesses, regardless of their turnover.

MTD for Income Tax Self Assessment (ITSA) follows a phased introduction based on gross qualifying income (total revenue before expenses from self-employment and property combined):

From April 2026: It becomes mandatory for those with a qualifying income over £50,000, making this the first group required to register.
From April 2027: The threshold drops to include those with a qualifying income between £30,000 and £50,000.
From April 2028: The threshold drops again to bring in those with a qualifying income between £20,000 and £30,000.

What Steps Should You Take to Set Up Your Chosen Software?

Download and install your selected software, then create a comprehensive business profile. Import existing financial data from spreadsheets, previous accounting systems, or other digital sources.

Configure your business details, including applicable tax codes and reporting periods. Connect banking integrations if your software supports automatic transaction importing features.

Test all functionality by entering sample transactions and verifying calculations appear correctly. Most importantly, ensure real-time tax calculations update accurately as you input data.

Last year, I helped a client import five years of spreadsheet data into their new MTD system. Though time-consuming initially, this preparation saved countless hours during quarterly submissions and eliminated manual entry errors.

How Do You Submit Your First MTD Return Successfully?

Verify all income and expenses are accurately recorded within your chosen software platform. Most applications highlight missing information or potential calculation errors before submission deadlines.

Review your figures thoroughly before quarterly deadlines approach to avoid last-minute corrections. Submit returns directly through your software interface, which automatically connects to HMRC systems.

You'll receive immediate confirmation of successful submission and processing by HMRC. However, maintain digital copies of all submissions for compliance records and future reference.

Remember that MTD for Income Tax includes quarterly updates plus year-end finalisation requirements.

What Are the Benefits of Making Tax Digital?

MTD offers significant time-saving advantages through automated calculations and streamlined processes. Digital record-keeping reduces manual data entry and eliminates the risk of losing paper receipts.

Real-time tax calculations provide better financial visibility throughout the year. This helps businesses make informed decisions and avoid unexpected tax bills at year-end.

Reduced errors represent another major benefit of digital systems over manual processes. MTD-compatible software includes built-in validation checks that catch common mistakes before submission.

Furthermore, quarterly reporting helps spread the administrative burden more evenly throughout the year. This prevents the last-minute rush traditionally associated with annual Self Assessment deadlines

What Common Mistakes Should You Avoid When Registering for MTD?

Avoid delaying registration and software setup until approaching compliance deadlines. Mixing paper records with digital systems creates compliance issues and complicates future audit processes.

Selecting software without proper HMRC connectivity causes ongoing submission difficulties and delays. Additionally, inadequate testing before first deadlines creates unnecessary stress and potential penalties.

Failing to maintain proper backup copies of digital records violates MTD requirements completely. Furthermore, ignoring HMRC updates regarding regulation changes can result in costly penalties and complications.
