Making Tax Digital – Part 2: Income Tax Self Assessment (ITSA)

The UK government is continuing its step-by-step digital transformation of the tax system. In our first article, we covered Making Tax Digital for Corporation Tax (MTD for CT). Now, it’s time to focus on Making Tax Digital for Income Tax Self Assessment (MTD for ITSA).

This reform directly affects self-employed individuals and landlords, requiring them—just like companies—to keep digital records and submit quarterly updates to HMRC, making tax compliance more transparent and manageable.

The phased implementation starts April 2026. This guide explains what MTD for Income Tax is, who will be affected, how to prepare, and the benefits of the change.

📂 What Is MTD for Income Tax?

MTD for Income Tax is part of the UK government’s broader digital tax reform. Its goal is to reduce errors, eliminate manual processes, andæ modernize the tax system.

Affected taxpayers will need to:

  • Keep digital records of income and expenses
  • Submit quarterly updates to
  • HMRC using MTD-compatible software file a Final Declaration at the end of the tax year

Who Will Be Affected?

MTD for Income Tax mainly applies to:

  • Self-employed individuals 🧑‍💻
  • Landlords with rental income 🏠

The rollout will be phased based on total annual income:

📌 6 April 2026 → Income over £50,000
📌 6 April 2027 → Income over £30,000
📌 6 April 2028 → Income over £20,000

(Income includes both self-employment and rental income.)

Individuals earning below £20,000 are currently out of scope.

📑 Key Requirements of MTD for Income Tax

Digital Record-Keeping
All income and expenses must be stored digitally using MTD-compliant software.

 Quarterly Updates
Instead of an annual return, taxpayers must submit quarterly income and expense updates.

 Final Declaration
After the tax year, a final declaration confirms the actual totals.

Penalty System ⚖️
HMRC will implement a points-based penalty for late or missing submissions. Accumulating points leads to financial penalties.
