MTD for Income Tax onboarding and quarterly filing service for sole traders and landlords is a UK business you could start with £1-5k in capital, with a realistic year-one revenue of £20-50k and first revenue in 1-3 months. It scores 9/10 Opportunity and 6/10 Validation Depth on the startup.compare framework.
From April 2026 a sole trader or landlord over £50,000 must keep digital records and file four quarterly updates plus a year-end return, five submissions where there was one. The people hit first are precisely those least likely to already run digital books: self-filing landlords and single-person traders. The obstacle is the standing-start jump from a shoebox or spreadsheet to compatible software and a quarterly rhythm, with a penalty for getting it wrong.
MTD for Income Tax is mandatory from 6 April 2026 for qualifying income over £50k (2027 over £30k, 2028 over £20k), hitting 864,000 people in the first wave (GOV.UK). The first quarterly update is due 7 August 2026, with a first-year soft landing on penalty points.
