# MTD for Income Tax Self Assessment Goes Live: Essential Guidance for Sole Traders and Landlords
**Published: 11 April 2026**
Making Tax Digital (MTD) for Income Tax Self Assessment (ITSA) is now live as of 6 April 2026. This marks a significant shift for approximately [864,000 sole traders and landlords](https://www.icaew.com/insights/tax-news/2026/feb-2026/prepare-for-2026-27-businesses) whose combined self-employment and property income exceeds £50,000 annually. From now on, these taxpayers must keep digital records and submit quarterly updates in place of a single annual Self Assessment return for those income sources.
## Who Is Affected?
The initial mandate targets those with **over £50,000** in relevant income. Thresholds will drop progressively:
– **£30,000** from April 2027
– **£20,000** from April 2028 ([HMRC announcement](https://www.gov.uk/government/publications/making-tax-digital-for-income-tax-self-assessment-reducing-the-mandation-threshold-from-30000-to-20000-from-april-2028/reduction-of-the-mandation-threshold-from-30000-to-20000-from-april-2028))
Income from self-employment, property rental, and ‘other’ miscellaneous (e.g., high-income child benefit charge) counts towards the threshold. Partnerships follow separate rules from 2026/27.
**Exemption for Cessations**: HMRC clarified on 2 April 2026 that if your qualifying business or property ceased *before* 6 April 2026—even if income exceeded £50k in 2025/26—you are exempt from MTD ITSA ([ICAEW insights](https://www.icaew.com/insights/tax-news/2026/apr-2026/hmrc-clarifies-position-on-making-tax-digital-and-cessations)).
## Key Changes: Digital Records and Quarterly Filing
– **Digital Records**: All records (invoices, receipts, bank statements) must be held digitally. Spreadsheets are allowed if MTD-compatible software imports them. Paper records are obsolete.
– **Quarterly Updates**: Four submissions per year (31 Aug, 31 Jan, 31 Jul after 5 Oct end), finalising the tax year declaration. Each update reconciles income/expenses to date against prior periods ([HMRC step-by-step](https://www.gov.uk/government/collections/making-tax-digital-for-income-tax-for-businesses-step-by-step)).
– **Software Requirement**: Use HMRC-recognised MTD ITSA software for submissions. List available [here](https://www.gov.uk/guidance/sign-in-to-your-making-tax-digital-for-income-tax-self-assessment-account-as-a-business).
HMRC’s ‘Edition 4: Ready, Steady, File!’ (published ~9 April) confirms the service is operational and urges testing ([download](https://www.gov.uk/government/publications/edition-4-ready-steady-file/edition-4-ready-steady-file)).
## New Penalty Regime
Separate from VAT penalties, MTD ITSA introduces a **points-based system**:
– Late submission: 2 points per instance
– Late payment: 2 points per quarter
– Triggers: £100 (1pt), £300 (4pts), £700 (repeated)
Maximum £3,000/year for repeated failures ([full guidance](https://www.gov.uk/guidance/penalties-for-making-tax-digital-for-income-tax)). No soft landing—full regime from day one.
## Adviser Sanctions from 1 April 2026
Tax advisers face **unlimited fines** for ‘sanctionable conduct’ (enabling deliberate non-compliance). HMRC can publicise names and details ([HMRC policy](https://www.gov.uk/guidance/how-hmrc-deals-with-tax-adviser-sanctions)).
## Broader Compliance Trends
– **Company Tax Returns**: HMRC consulting on standardised digital formats (March 2026–Sep 2026) ([consultation](https://www.gov.uk/government/consultations/modernising-and-standardising-company-tax-returns–2/modernising-and-standardising-company-tax-returns)).
– **Tax Gap**: HMRC targets 5.3% gap closure via compliance yields ([Feb 2026 stats](https://www.gov.uk/government/publications/hmrc-performance-update-february-2026/hmrc-performance-data-2025-to-2026-february–2)).
## CFO Practical Steps
1. **Audit Income**: Confirm if over £50k threshold (self-employment + property).
2. **Choose Software**: Test MTD-compatible tools now—e.g., QuickBooks, Xero integrations.
3. **Train Staff**: Quarterly cadence requires process changes.
4. **Test Sign-Up**: Register via [Government Gateway](https://www.gov.uk/log-in-register-hmrc-online-services).
5. **Scenario Plan**: Model penalties; budget for compliance costs.
For partnerships/Corporates, align with CT600 modernisation.
## Turnaround Angle
Distressed businesses: MTD adds pressure—non-compliance risks liquidation. Prioritise digital transition in workout plans.
