2025 VAT Thresholds UK: Registration, Deadlines & Penalties Explained

Navigating VAT compliance can feel like walking a tightrope—one missed deadline or miscalculation could lead to hefty penalties. With the VAT registration threshold rising to £90,000 and new Making Tax Digital (MTD) rules in force, 2025 brings both opportunities and challenges for UK small businesses. This guide cuts through the complexity, offering clarity on thresholds, deadlines, and strategies to stay compliant.
Understanding the 2025 VAT Threshold
What’s New in 2025?
- Registration Threshold: Increased from £85,000 to £90,000 (effective April 2024)
- Deregistration Threshold: Raised from £83,000 to £88,000 (excluding Northern Ireland)
- Frozen Until 2026: No further increases expected, giving businesses stability
Why This Matters
The UK’s VAT threshold remains the highest in the OECD, keeping 3.2 million small businesses outside the VAT system. However, crossing the £90k mark triggers mandatory registration within 30 days—calculated on a rolling 12-month basis, not the tax year

Preparation Steps for 2025
