Making Tax Digital 2025: What Agency Owners Need to Know Now
Making Tax Digital is expanding dramatically in 2025-2026, and UK agencies with income over £50,000 will be required to comply from 6 April 2026. If you're an agency owner confused about MTD requirements, deadlines, and software choices, this comprehensive guide will get you compliant and prepared.
🚨 Critical Compliance Deadlines for 2025-2026
What is Making Tax Digital and Why Should Agencies Care?
Making Tax Digital (MTD) is HMRC's initiative to modernize the UK tax system by requiring digital record-keeping and quarterly reporting. For agency owners, this represents a fundamental shift from annual Self Assessment returns to quarterly digital submissions throughout the tax year.
Why This Matters for Agencies:
- Project-based income: Agencies often have variable revenue that needs quarterly tracking
- Multiple income streams: Many agencies mix retainer and project work
- Expense complexity: Client entertainment, marketing costs, and equipment purchases need proper categorization
- Cash flow implications: Quarterly reporting means better financial visibility and planning
Do You Need to Comply? The Agency Income Check
Based on the latest HMRC guidance updated September 2025, you must use Making Tax Digital for Income Tax if all of these apply:
MTD Requirements Checklist:
- ✓You're a sole trader or landlord registered for Self Assessment
- ✓You get income from self-employment or property (or both)
- ✓Your qualifying income exceeds the threshold for your tax year
Qualifying Income Thresholds for Agencies
| Tax Year | Income Threshold | MTD Start Date |
|---|---|---|
| 2024-2025 | Over £50,000 | 6 April 2026 |
| 2025-2026 | Over £30,000 | 6 April 2027 |
| 2026-2027 | Over £20,000 | TBA (Legislation pending) |
For most UK agencies, this means: If your agency generates more than £50,000 in qualifying income for the 2024-2025 tax year, you must be ready for MTD by April 6, 2026. HMRC will review your Self Assessment return and notify you if you're above the threshold.
