Step 1: Are you the right type of taxpayer?
MTD for Income Tax applies to individuals who file Self Assessment and have either self-employment or property income. That includes:
- Sole traders (any trade, any industry)
- CIS subcontractors filing Self Assessment
- UK landlords
- Overseas landlords with UK rental income
It does not currently apply to limited companies, general partnerships (still to be confirmed) or people whose only self-employment is under £1,000 (the trading allowance).
Step 2: Add up your gross income
Take your latest Self Assessment return and add together:
- Total gross self-employment turnover (before expenses)
- Total gross UK and overseas property income (before expenses)
That combined number is your qualifying income. Ignore your PAYE salary, dividends, savings interest and pension income — none of those count towards the threshold.
Step 3: Match your income to a start date
Once you have your qualifying income figure, work out when MTD applies to you:
- Over £50,000: MTD from 6 April 2026
- £30,001 to £50,000: MTD from 6 April 2027
- £20,001 to £30,000: expected from April 2028
- £20,000 or under: not in scope yet
Step 4: If MTD applies, what next?
You need three things in place by your start date:
- MTD-compatible software (Fixxa is built to keep the digital records MTD requires)
- A Government Gateway account signed up for MTD for Income Tax
- A routine for filing quarterly updates and the Final Declaration each year
Even if you are in the £20,000-and-under group, it is worth starting to keep digital records now. HMRC has signalled the threshold will come down over time.
