Car tax appeals UK — if you disagree with a DVLA road tax decision, you have the right to challenge it. Here is how the appeals process works in 2026.
When Can You Appeal a VED Decision?
- Incorrect CO2 figure: DVLA has recorded the wrong emissions for your vehicle
- Wrong fuel type: Your vehicle is taxed as petrol when it is electric or alternative fuel
- First-year vs standard rate: DVLA is applying the wrong rate category to your vehicle
- Premium rate error: Your vehicle is incorrectly flagged as over the £40,000 threshold
- Exemption wrongly refused: Your vehicle qualifies for a historic or disabled exemption that DVLA has rejected
How to Start an Appeal
Contact DVLA in writing with your vehicle registration number, V5C reference number, and a clear explanation of why you believe the decision is wrong. Include supporting evidence such as the V5C registration certificate, Certificate of Conformity, manufacturer letter, or MOT certificate showing the correct CO2 figure.
DVLA Response and Internal Review
DVLA will review your appeal and respond within a defined timeframe. If they uphold their original decision, they will explain their reasoning. You can request an internal review of the decision if you are not satisfied with the first response. Keep copies of all correspondence for your records.
Vehicles Certification Appeals
If the issue relates to the vehicle's type approval or CO2 certification, you may need to go through the Vehicle Certification Agency (VCA) rather than DVLA. The VCA handles type approval certification for vehicles — if your vehicle's CO2 data is incorrect at the type approval level, the correction must come from the VCA.
Conclusion
Car tax appeals UK: write to DVLA with evidence if you believe a decision is wrong. Include V5C and CoC as evidence. DVLA contact details available at GOV.UK.
