What is MTD for Income Tax?
Making Tax Digital for Income Tax Self Assessment (MTD ITSA) is HMRC's programme to modernise the way sole traders and landlords report their income and expenses. Rather than filing a single annual tax return, you'll keep digital records throughout the year and submit quarterly updates directly to HMRC via compatible software.
At the end of each tax year you'll file an End of Period Statement (EOPS) for each income source, followed by a Final Declaration that brings everything together — replacing what was previously your Self Assessment return.
The quarterly updates aren't tax payments — they're summaries of your income and expenses so HMRC can build a more accurate real-time picture of your tax position throughout the year.

You'll need to comply with MTD for Income Tax if you're a sole trader or landlord (or both) and your total qualifying income from self-employment and property exceeds £50,000 in a tax year. HMRC will assess your eligibility based on the income reported in your most recent Self Assessment return.
If you have income from multiple sources — for example, freelance work plus rental income — both streams count towards the threshold. If your combined income crosses £50,000, you're in scope from April 2026.
Limited exemptions may apply in certain circumstances, such as insolvency, digital exclusion, or religious grounds. HMRC can grant deferrals in exceptional cases.

Once in scope, you'll have four quarterly submission deadlines per year. Below are the standard quarterly windows and their filing dates:
| Quarter | Period covered | Submission deadline |
|---|---|---|
| Q1 | 6 April – 5 July | 7 August |
| Q2 | 6 July – 5 October | 7 November |
| Q3 | 6 October – 5 January | 7 February |
| Q4 | 6 January – 5 April | 7 May |
After the year ends, your End of Period Statement is due by 31 January (following the tax year), followed by your Final Declaration.
