MTD is Coming for Your Business: The £10,000 Mistake 99% of Small Businesses Will Make

If you’re a sole trader or landlord earning over £50,000, there’s a massive change heading your way that could cost you thousands if you get it wrong. Making Tax Digital (MTD) for Income Tax launches in April 2026, and frankly, most small businesses are sleepwalking into a compliance nightmare.

The MTD Timeline: When It Affects You

• 1 April 2026: MTD for Income Tax starts for sole traders and landlords with qualifying income over £50,000
• By End of Parliament: Threshold drops to £20,000 following Autumn Budget 2024 announcement
• April 2028: Labour government enforces MTD for landlords with £20,000+ income or face fines

The penalties for getting this wrong aren’t just a slap on the wrist. We’re talking about cascading fines, penalty points, and compliance costs that could easily hit £10,000 or more for unprepared businesses.

What Exactly Is Making Tax Digital for Income Tax?

Making Tax Digital isn’t just another bureaucratic hurdle – it’s a fundamental shift in how HMRC expects you to manage your tax affairs.

• Digital Record Keeping: Every transaction, expense, and piece of income must be recorded digitally using MTD-compatible software.
• Quarterly Reporting: Submit updates four times a year by the 7th of each month. No more annual submissions.
• Digital Links: All data must flow seamlessly between your accounting software and HMRC’s systems without manual intervention.

The £10,000+ Penalty Trap

The new penalty system isn’t just about late filing – it’s a points-based system that can quickly spiral out of control.

• Every late submission earns penalty points
• Four points threshold for quarterly filers
• £200 fine when threshold is reached
• Points expire after two years if threshold not reached
• If VAT Return and MTD deadlines fall on the same day, you could face £400 in penalties for one late submission

Critical Compliance Mistakes to Avoid

• Software Selection Nightmare: Research and test MTD-compatible software now.
• Digital Records Chaos: Scanning receipts isn’t enough. You need proper electronic record-keeping.
• Quarterly Reporting Confusion: Be prepared for 12 extra deadlines each year.
• Inadequate Preparation Time: Transitioning takes months of planning and testing.
