This checklist is an essential resource for accountants and tax professionals preparing for Making Tax Digital (MTD) for Income Tax Self-Assessment (ITSA). It provides a structured, step-by-step guide to ensure compliance with HMRC’s new digital tax reporting requirements. By following the outlined steps, accountants can help their clients transition seamlessly to the new system before the mandatory start dates, avoiding last-minute complications and potential penalties. 

What is MTD for ITSA? 

MTD for ITSA is part of HMRC’s broader initiative to modernise the UK tax system by requiring digital record-keeping and online submissions. It applies to sole traders and landlords whose annual gross incomes exceed £30,000. The goal is to improve efficiency, reduce tax errors, and make tax administration more transparent and streamlined. 

Under MTD for ITSA, affected taxpayers must: 

  • Maintain digital records of income and expenses using compatible accounting software. 
  • Submit quarterly updates to HMRC, providing real-time tax information instead of the traditional annual tax return. 
  • Adhere to revised reporting requirements, with penalties for non-compliance. 

Implementation timeline

The rollout of MTD for ITSA will be phased to allow businesses to adjust: 

  • April 2026: Mandatory for those earning over £50,000 annually. 
  • April 2027: Mandatory for those earning over £30,000 annually.
