## What is MTD for Income Tax Self Assessment (ITSA)?
Making Tax Digital for Income Tax Self Assessment (MTD ITSA) became effective from **6 April 2026** for sole traders and property landlords earning over £50,000 annually. Under MTD, individuals must keep digital records and submit **quarterly updates** to HMRC using software compatible with the system. ([gov.uk](https://www.gov.uk/government/publications/hmrc-transformation-roadmap-progress-update-2026/hmrc-transformation-roadmap-update-2026?utm_source=openai))
## Key Requirements and Timelines
| Requirement | Who it affects | From | Details |
|-------------|----------------|------|---------|
| Digital record keeping & quarterly updates | Sole traders & landlords with income >£50,000 | 6 April 2026 | Must use compatible commercial software; first quarterly update due July/August depending on accounting period. ([gov.uk](https://www.gov.uk/government/publications/hmrc-performance-update-april-to-june-2026/hmrc-performance-update-2026-to-2027-quarter-1?utm_source=openai))|
| Submission of other tax returns | All affected by Self Assessment | After 4th quarterly update | Final Self Assessment still required, but quarterly updates must cover most income/property entries. ([gov.uk](https://www.gov.uk/guidance/use-making-tax-digital-for-income-tax/updates?utm_source=openai))|
| Mid-year changes and corrections | Same as above | Ongoing | Must amend digital records promptly if income sources change. ([gov.uk](https://www.gov.uk/guidance/use-making-tax-digital-for-income-tax/updates?utm_source=openai))|
## Practical Steps to Comply
- Choose and set up **compatible software** in time. Ensure it supports both income and property record entries.
- Keep **detailed records**: as soon as you have invoices, receipts, or logs, digitally record them. Do **not delay** until the end of a quarter.
- Understand **update periods** and deadlines: get ahead so you’re not caught out by late submissions or penalties.
## Example Scenario
Sarah is a sole trader earning £60,000 a year from selling handmade furniture and gets about £10,000 from renting a room in her home. From 6 April 2026, she must:
- Use compatible software to record both her trade and property income throughout the year.
- Send quarterly updates (e.g. covering up to 5 April–6 July, 6 July–5 October, etc.) showing totals to date.
- After her fourth update, submit the full Self Assessment return including all income and deductions.
If Sarah buys a new camera mid-tax year and uses it in her trade, she must record the purchase in her digital records as soon as possible. If she delays, the quarterly update won’t reflect that deduction.
## What Happens if You Don’t Comply
- Errors or omissions in digital records or updates may lead to **penalties** or interest.
- HMRC is phasing in penalty regimes; professional software and agent support can help avoid mistakes.
- Being late with quarterly updates might also mean unexpected tax bills—don’t let cash-flow surprises catch you unprepared.
## Where to Find Support and Resources
- HMRC’s published guidance on **Use Making Tax Digital for Income Tax** (guidance includes update periods, deadlines, correcting errors) ([gov.uk](https://www.gov.uk/guidance/use-making-tax-digital-for-income-tax/updates?utm_source=openai)).
- Actionable checklists and software-comparison tools.
- Tax advisors experienced with small business or landlord finances.
**Bottom line:** If you’re a trader or landlord in the UK with income above £50,000, you must now keep digital records and file quarterly updates. Getting software right, staying organized, and being aware of deadlines can turn MTD from a burden into a tool for better cash-flow and planning.
