How this calculator works
Enter fuel type and CO₂ (g/km). The tool applies a simplified published-rate model for cars first registered under CO₂-based rules. It may not cover every vehicle class, classic exemptions or diesel surcharges exactly as currently enforced.
Limitations
Rules version: October 2026 review. We will update the calculator when rates change. This is not legal advice and not a substitute for GOV.UK tax tables.
