## What is MTD for ITSA?
**Making Tax Digital for Income Tax Self Assessment (MTD for ITSA)** is a UK government initiative to modernise how self-employed individuals and landlords report income and expenses. Rather than filing once per year, you'll report **quarterly updates** via software from financial year starting **6 April 2026**.

## Who’s affected and when it applies
| Group | Income threshold | Required start date |
|---|---|---|
| Sole traders & landlords with income over **£50,000** from self-employment and/or property | >£50,000 | From 6 April 2026 ([gov.uk](https://www.gov.uk/government/publications/extension-of-making-tax-digital-for-income-tax-self-assessment-to-sole-traders-and-landlords/making-tax-digital-for-income-tax-self-assessment-for-sole-traders-and-landlords?utm_source=openai)) |
| Those with income between **£30,000-£50,000** | >£30,000 | From 6 April 2027 ([gov.uk](https://www.gov.uk/government/publications/extension-of-making-tax-digital-for-income-tax-self-assessment-to-sole-traders-and-landlords/making-tax-digital-for-income-tax-self-assessment-for-sole-traders-and-landlords?utm_source=openai)) |
| Those with income over **£20,000** | >£20,000 | From 6 April 2028 ([gov.uk](https://www.gov.uk/government/publications/extension-of-making-tax-digital-for-income-tax-self-assessment-to-sole-traders-and-landlords/making-tax-digital-for-income-tax-self-assessment-for-sole-traders-and-landlords?utm_source=openai)) |
## Key changes and what stays the same
### What’s new:
- **Quarterly updates**: Submit summaries of income, expenses, and reliefs every quarter. ([makingtaxdigital.campaign.gov.uk](https://makingtaxdigital.campaign.gov.uk/quarterly-updates/?utm_source=openai))
- **End-of-year Final Declaration**: Confirm and finalise what’s already reported. ([developer.service.hmrc.gov.uk](https://developer.service.hmrc.gov.uk/guides/income-tax-mtd-end-to-end-service-guide/index.html?utm_source=openai))
- **Digital-enabled record-keeping and software**: All affected individuals must use MTD-compatible digital tools. ([developer.service.hmrc.gov.uk](https://developer.service.hmrc.gov.uk/guides/income-tax-mtd-end-to-end-service-guide/index.html?utm_source=openai))
### What stays the same:
- **Tax payment deadlines**, such as the 31 January deadline for payment of balancing payment, are unchanged. ([makingtaxdigital.campaign.gov.uk](https://makingtaxdigital.campaign.gov.uk/quarterly-updates/?utm_source=openai))
- **Amount of tax owed** is based on the same calculations, not altered by reporting frequency.
- **Obligations to keep records** already existed, but now the timing and format change; many record-keeping duties remain.
## Examples
- **Alice**, a landlord earning £60,000/year from rental: she must submit quarterly income/expenses updates for tax and Class 4 NICs from April 2026. At year end, she still files a Final Declaration.
- **Ben**, a sole trader with £35,000 income: doesn’t need to join MTD for ITSA until 6 April 2027. Before then, can sign up voluntarily.
## Practical preparation steps
1. **Choose software early** — use HMRC’s software list to find tools compatible with MTD for Income Tax. ([developer.service.hmrc.gov.uk](https://developer.service.hmrc.gov.uk/guides/income-tax-mtd-end-to-end-service-guide/index.html?utm_source=openai))
2. **Start digital record-keeping now** — even before being required, build habits to gather receipts, invoices, bank statements in digital form.
3. **Watch cash flow** — more frequent reporting can highlight tax liabilities earlier, helping with budgeting.
4. **Know your income types** — self-employment, property income, and some other income sources count toward thresholds. PAYE income usually doesn’t count. ([developer.service.hmrc.gov.uk](https://developer.service.hmrc.gov.uk/guides/income-tax-mtd-end-to-end-service-guide/index.html?utm_source=openai))
5. **Seek deferrals or exemptions if needed** — HMRC offers digital-exempt options for those with accessibility or capability barriers.
## Common pitfalls to avoid
- Under-estimating income sources and crossing thresholds unexpectedly.
- Failing to ensure your software meets HMRC minimum functionality standards.
- Missing quarterly deadlines — these are new and enforceable.
- Overlooking important reliefs or expenses that can reduce tax burden.
**Bottom line:** If you're a sole trader or landlord with qualifying income, MTD for ITSA is now your reality from April 2026 (if over £50,000). Early planning will save headaches, improve accuracy, and ensure smoother compliance.
