Car tax error UK — if you have been charged the wrong Vehicle Excise Duty rate, you can challenge it. Here is how to correct VED errors and claim refunds from DVLA in 2026.
Common VED Errors
- Wrong CO2 figure: Your vehicle has been taxed at the wrong CO2 band, either too high or too low
- Fuel type wrong: Diesel vehicle taxed as petrol or vice versa, leading to incorrect VED
- First-year vs standard: A vehicle incorrectly paying first-year rates after year 1
- Zero-emission not applied: An EV incorrectly charged standard rate
How to Report a VED Error
Contact DVLA directly with your vehicle registration number and V5C reference. Explain the error and provide supporting evidence — your V5C showing the correct CO2 figure, or the Certificate of Conformity from the manufacturer. DVLA can correct the record and adjust future billing.
Claiming a VED Refund
If you have overpaid road tax due to an incorrect VED charge, you can claim a refund. DVLA will calculate the overpayment and issue a refund to the registered keeper's bank account or address. Refund claims should be made promptly — DVLA typically processes refunds within 4-6 weeks.
Reducing Future VED If You Have Been Undercharged
If you have been undercharged (your fault, not DVLA's), you will need to pay the shortfall. DVLA may issue a notice requiring payment of the difference. Penalties do not typically apply for genuine errors but persistent underpayment can result in enforcement action.
Conclusion
Car tax error UK can be corrected by contacting DVLA with evidence. Refunds are available for overpayments. Contact DVLA to resolve any VED discrepancy.
