The DVLA service tells you whether a car is taxed. That is it. CarCostCheck uses the same DVLA data but adds:
- Exact annual tax cost in pounds, calculated from the car's CO2 band
- Full MOT history with advisories explained
- Reliability score from 0 to 100
- Fuel cost estimate based on mileage and engine type
- Total annual running cost (tax + fuel + MOT + predicted repairs)
One lookup, ten seconds, no payment, no email.
UK vehicle tax works differently depending on when the car was first registered:
- Before March 2001: Based on engine size. Two bands: under 1549cc (£200) or over 1549cc (£325).
- March 2001 to March 2017: Based on CO2. 13 bands ranging from £0 (Band A) to £735 (Band M).
- From April 2017: First year based on CO2 (£10-£2,905 for highest-emitting petrol/diesel), flat £195 from year two onwards. Cars over £40,000 list price pay an additional £425 "expensive car supplement" for 5 years.
All of these bands are calculated automatically in the CarCostCheck free report based on the car's registration date and DVLA CO2 data.
- Assuming tax transfers with the car. It does not. As of October 2014, tax is non-transferable. The previous owner gets a refund, and you must tax the car from the day you take ownership.
- Driving off untaxed. Even a few miles home can trigger an automatic penalty if ANPR cameras catch the car.
- Forgetting the annual cost. A cheap car can have £500+ annual tax if it was registered in the 2010-2017 high-CO2 era. Always check the cost before buying.
Is the car tax check really free?
Yes, and it always has been. Tax data is released by DVLA under the Open Government Licence and any service charging for it is reselling free data.
How long does a tax check take?
CarCostCheck returns results in under 10 seconds. The DVLA service is similar.
Can I tax a car on CarCostCheck?
No, CarCostCheck only shows you the status and cost. To actually tax a vehicle, use the DVLA's own service with your V5C reference number.
