Making Tax Digital (MTD) for Self-Assessment – April 2025 Update

Published: 10 June 2025

The UK government’s Making Tax Digital (MTD) for Income Tax Self-Assessment (ITSA) initiative is set to go live from April 2025. This new system will change how self-employed individuals and landlords report their income tax, requiring them to keep digital records and submit tax updates through HMRC-approved software.

Who Needs to Comply with MTD for Self-Assessment in April 2025?

From April 2025, MTD for ITSA will apply to self-employed individuals and landlords with an annual turnover exceeding £50,000.

From April 2026, the threshold will lower to £30,000, bringing more taxpayers into the system.

Key Changes Under MTD for Self-Assessment

1. Digital Record-Keeping

  • Taxpayers must use compatible software to maintain income and expense records.
  • Spreadsheets alone will no longer be sufficient unless linked to bridging software.

2. Quarterly Tax Reporting

  • Instead of a single annual tax return, businesses and landlords must submit quarterly updates (every 3 months) to HMRC.
  • Deadlines for quarterly updates are expected to be 5 August, 5 November, 5 February, and 5 May.

3. End-of-Year Submission

  • An annual Final Declaration (replacing the Self-Assessment return) must be submitted by 31 January following the tax year.
  • This will confirm total earnings and tax owed.

Benefits of MTD for Self-Assessment

  • Improved Tax Accuracy – Reduces errors from manual tax calculations.
  • Better Financial Visibility – Regular updates help taxpayers manage cash flow.
  • More Efficient Process – Digital submissions streamline tax reporting.
