Making Tax Digital (MTD) for Income Tax is being phased in from April 2026. From 6 April 2026, sole traders and landlords with turnover over £50,000 must keep digital records and submit quarterly updates to HMRC. The threshold drops to £30,000 from April 2027. If your turnover is below £30,000, you do not have to use MTD.
The MTD timeline
- 6 April 2026: sole traders and landlords with turnover over £50,000 must use MTD for Income Tax

What "MTD for Income Tax" actually means
- Keep digital records of your income and expenses (spreadsheets do not count unless linked to MTD-compatible bridging software)
- Submit a quarterly update to HMRC, summarising your income and expenses for the quarter
- Submit a final declaration at the end of the tax year, replacing the current self-assessment tax return
How often do the quarters land?
- Q1: 6 April to 5 July (update due 5 August)
- Q2: 6 July to 5 October (update due 5 November)
- Q3: 6 October to 5 January (update due 5 February)
- Q4: 6 January to 5 April (update due 5 May)
- Final declaration: due 31 January following the end of the tax year
Which software is MTD-compatible?
To submit MTD updates, you need software that has been through HMRC's MTD conformance test. The current list includes Xero, QuickBooks, FreeAgent, Sage, KashFlow, and HMRC's own MTD bridging software for spreadsheets. If your existing accounting software is not on the list, you will need to switch.
What does this mean for Invosi users?
Invosi is invoicing software, not accounting software, so it does not file your MTD returns directly. But Invosi integrates with the major accounting software (Xero, QuickBooks, FreeAgent) so your invoice data flows through automatically to your MTD submissions.
