Overview
- Mandatory use begins in phases based on qualifying income from self-employment and property: over £50,000 from April 2026, over £30,000 from April 2027, and over £20,000 from April 2028.
- HMRC correspondence says those in scope will be legally required to use Making Tax Digital for Income Tax, with notifications going to taxpayers identified by their qualifying income.
- Quarterly digital updates and a year-end declaration via MTD‑compatible software will replace the single annual Self Assessment return, including an End of Period Statement and a Final Declaration by 31 January.
- HMRC highlights updated penalties for late submissions and payments once enrolled, with certain groups able to claim exemption if they face disproportionate barriers and notify HMRC.
- Ministers say they will explore extending digitalisation benefits to people below the £20,000 threshold, though no changes for that group have been confirmed.
