From 6 April 2026, the first wave of 860,000 sole traders and landlords must use digital software to manage their tax affairs.
This marks the beginning of the most significant shift in self-employment taxation in a generation.
The new Making Tax Digital for Income Tax (MTD ITSA) system will be rolled out over three years, starting with those earning over £50,000 a year.
The threshold will progressively lower to £30,000 from April 2027 and to £20,000 from April 2028, eventually bringing up to three million more self-employed people into the digital regime.
Staggered roll-out
The phased approach mirrors HMRC's existing Making Tax Digital for VAT programme.
Under that, all VAT-registered businesses in the UK with a taxable turnover above £90,000 must keep digital records and use software to submit their tax returns.
Here are the important dates for MTD ITSA.
