Does MTD Apply to Your Self-Employment Income?
MTD for Income Tax applies to sole traders — those who are self-employed and not trading through a limited company — whose total qualifying income exceeds the threshold. Qualifying income includes your self-employment income plus any property rental income combined. The threshold has been £50,000 since April 2026, dropping to £30,000 from April 2027 and £20,000 from April 2028.
What Sole Traders Must Do Under MTD
- Determine whether your qualifying income exceeds the MTD threshold.
- Choose HMRC-compatible MTD software.
- Register for MTD for Income Tax on your Government Gateway account.
- Record all business income and allowable expenses digitally throughout the year.
- Submit four quarterly updates per year.
- Complete and submit your Self Assessment tax return through MTD-compatible software after the tax year.
MTD for Sole Traders with Multiple Trades
If you run more than one self-employed trade, each business is reported separately under MTD — you send a separate quarterly update for each trade, not one combined figure. Your MTD software must support multiple businesses, and you need to keep digital records for each one distinctly. For the qualifying-income threshold test, though, HMRC combines the gross turnover from every trade plus any property income — so someone with a £30,000 consultancy and a £25,000 online shop has £55,000 of combined qualifying income, over the £50,000 threshold, even though each trade is reported separately once you’re in MTD.
Quarterly Update Deadlines for Sole Traders
Once you’re in MTD, you send four cumulative quarterly updates a year, plus a year-end tax return. Using the standard tax-year quarters:
- 6 April – 5 July — due 7 August
- 6 April – 5 October (cumulative) — due 7 November
- 6 April – 5 January (cumulative) — due 7 February
- 6 April – 5 April (cumulative) — due 7 May
Your Self Assessment tax return is then due by 31 January after the tax year ends — the same date that's applied under Self Assessment for years. You can elect to use calendar-month quarters instead if that suits your bookkeeping better; the submission dates stay the same.
Just Started as a Sole Trader?
HMRC decides your MTD start date using your most recently submitted Self Assessment return, so if you’ve only just registered as self-employed you won’t yet have a qualifying-income figure on record. In practice this means brand-new sole traders normally aren’t brought into MTD until their income history catches up — but it’s worth keeping digital records from day one so you’re ready when you are assessed.
What Counts as Qualifying Income?
Qualifying income for MTD purposes is your gross income before expenses — not your profit. It includes income from self-employment and from property letting, combined. So a sole trader with £45,000 of turnover and heavy expenses that leave only £18,000 of actual profit is still assessed on the £45,000 figure, and stays below the current £50,000 threshold on that basis alone. Employment income, savings interest, dividends and pensions are not counted towards the qualifying-income test.
MTD Software for Sole Traders
HMRC maintains a list of recognised MTD-compatible software. FreeAgent and Coconut are popular with sole traders and freelancers for mobile-first record-keeping, Xero and QuickBooks suit busier or VAT-registered businesses, and bridging software lets you keep working in a spreadsheet while staying compliant.
