Making Tax Digital for Income Tax (MTD ITSA)

A Complete Guide for UK Businesses Using Sage Software

Making Tax Digital (MTD) for Income Tax is changing how UK businesses and landlords report their earnings to HM Revenue & Customs. If you're a sole trader or property owner, preparing now with the right tools—like Sage software—will help you stay compliant and in control.

What is Making Tax Digital for Income Tax?

Making Tax Digital for Income Tax (MTD ITSA) is part of the UK government’s initiative to digitise the tax system. Instead of submitting a single annual Self-Assessment, you’ll maintain digital accounting records and send quarterly tax updates using MTD-compatible software.

Key benefits:

  • Improved tax accuracy
  • Fewer manual errors
  • Real-time financial insights
  • Better tax planning and cash flow control

Who Needs to Comply with MTD ITSA?

MTD for Income Tax applies to:

  • Sole traders
  • Landlords with UK property income

MTD rollout dates:

  • April 2026 – Income over £50,000
  • April 2027 – Income over £30,000
  • April 2028 – Income over £20,000

If your income exceeds these thresholds, you’ll need to use MTD-compliant accounting software.

Exemptions

You may qualify for exemption if:

  • You cannot use digital systems due to age, disability, or location
  • You receive approval from HMRC

Limited companies are not included in MTD for Income Tax.

How Making Tax Digital Works

  1. Keep Digital Accounting Records

You must store all financial data digitally, including:

  • Business income
  • Expenses
  • Rental income

Manual or paper-based bookkeeping alone will not meet MTD requirements.

  1. Submit Quarterly Updates to HMRC

You’ll send four quarterly submissions per year using Sage accounting software.

Each update includes:

  • Total income
  • Total allowable expenses

These updates provide HMRC with a regular overview of your finances.

  1. Complete Your Final Declaration

At year end, you’ll submit a final declaration to:

  • Confirm your total income
  • Make accounting adjustments
  • Declare additional earnings

This replaces the traditional Self-Assessment tax return.

How Often Will You Submit?

Under MTD ITSA, you’ll complete:

  • 4 quarterly updates
  • 1 final submission

This means more frequent reporting—but greater visibility and control.
