About
About cartax.org.uk
cartax.org.uk is an independent UK car tax guide built to make Vehicle Excise Duty easier to check on a phone while comparing cars. The site uses public April 2026 VED rules and presents them in a clearer buying-flow format.
VED-focused rules engine
The calculation logic is powered by the VED.org.uk data engine, which is the technical layer behind the published 2026/27 Vehicle Excise Duty estimates.
Independent guidance
This site is an independent guide. It is not affiliated with GOV.UK, DVLA or HMRC and it does not represent an official government service.
Methodology
- Manual VED calculations are based on published April 2026 rates and supporting guidance.
- The calculator supports the post-2017 standard-rate system, the 2001 to 2017 CO2 bands, and pre-2001 engine-size bands.
- For live taxed or untaxed status, users are sent to the official GOV.UK checker rather than an unofficial cached lookup.
