HM Revenue & Customs (HMRC) has published a policy paper introducing a measure to lower the Making Tax Digital (MTD) for Income Tax mandation threshold from £30,000 to £20,000 from 6 April 2028, thereby bringing around 970,000 additional sole traders and landlords into scope of digital record-keeping and quarterly reporting requirements using compatible software. The measure aims to improve tax accuracy, reduce errors, and support the transition to a modern digital tax system, building on the phased rollout of MTD since 2019. Implemented through the Income Tax (Digital Obligations) Regulations 2026, it amends the definition of mandated taxpayers and provides for exemptions where digital compliance is not feasible. The policy is expected to increase Exchequer revenue, reaching £155m annually by 2030–31, without significant macroeconomic or wider household impacts. Affected individuals are expected to incur transitional and ongoing compliance costs, estimated at £380m and £101m per year respectively, although these may be partly offset by benefits such as reduced administrative errors, time savings, and improved financial management. HMRC will provide support for affected taxpayers and monitor the measure’s effectiveness through ongoing evaluation.
