MTD for Income Tax Self Assessment (MTD ITSA) is phased in by qualifying income — self-employment plus property gross income: above £50,000 from 6 April 2026, above £30,000 from April 2027 and above £20,000 from April 2028. Once in, you file four quarterly updates plus a final declaration each year using compatible software, with a points-based late-submission penalty.
£60,000 self-employment income mandates MTD from 6 April 2026 — five submissions a year, ~£300 estimated compliance cost, and a £200 worst-case penalty if all quarterly updates are missed.
