Key takeaway: Car tax checks are always free. The DVLA's own service shows the current tax status, and CarCostCheck shows the tax status with a cost estimate in seconds. Any service charging for a tax check is selling what the government gives away. Use CarCostCheck for the combined report: tax plus MOT plus running costs in one place.

What a Car Tax Check Shows

A car tax check returns three things:

  1. Current status: Is the car taxed, untaxed (SORN), or untaxed (late)?
  2. Tax band: The band the car sits in, based on CO2 emissions and first registration date.
  3. Annual cost: How much you will pay to tax the car for 12 months.

The underlying data comes from the DVLA. The DVLA's own service is the most up-to-date source. CarCostCheck's report uses DVLA data refreshed at least once a week, so if a car was taxed in the last few days, confirm it on GOV.UK.

The paid services do not offer anything extra on the tax check itself, they are charging for the other history data (stolen, finance, write-off). If all you want is tax, go free every time. The same goes for MOT history, mileage and recalls: our free car check guide lists what is free and what is not.

Why CarCostCheck Beats the DVLA's Own Service

The DVLA service tells you whether a car is taxed. That is it. CarCostCheck uses the same DVLA data but adds:

  • Annual tax cost in pounds, worked out from the car's registration date and 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.

What the 2026 Tax Rates Actually Are

UK vehicle tax works differently depending on when the car was first registered:

  • Before March 2001: Based on engine size. Two bands: up to 1549cc (£230) or over 1549cc (£375).
  • March 2001 to March 2017: Based on CO2. 13 bands ranging from £20 (Band A) to £790 (Band M).
  • From April 2017: First year based on CO2 (£10 to £5,690), then the £200 standard rate from year two onwards. Cars with a list price over £40,000 (over £50,000 for an electric car registered from April 2025) pay an additional £440 "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.

Common Mistakes When Buying a Car

  1. 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.
  2. Driving off untaxed. Even a few miles home can trigger an automatic penalty if ANPR cameras catch the car.
  3. 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.

Frequently Asked Questions

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.

Frequently Asked Questions

What is the cheapest way to check if a car is taxed?

Free. The DVLA's own service shows the current tax status, and CarCostCheck shows the tax status with the annual cost, using just the registration. Never pay for a car tax check; the data is free under the Open Government Licence.

Does CarCostCheck show tax status?

Yes. The free CarCostCheck report includes the tax status, tax band, and annual tax cost alongside MOT history, mileage verification, and running cost estimates. No sign-up required.

What happens if I buy an untaxed car?

The car cannot legally be driven on public roads or parked on them until you tax it in your own name. DVLA may have already applied penalties to the previous keeper. Always check tax status before buying and budget for taxing the car the day you take ownership.

How much is car tax in the UK 2026?

It depends on CO2 emissions and first registration date. Cars registered from April 2017 pay £10 to £5,690 in year one (based on CO2), then the standard rate of £200 a year from year two, plus £440 a year for five years if the list price was over £40,000 (over £50,000 for an electric car registered from April 2025). Older cars follow a different band system. CarCostCheck shows the figure for any registration.
