Company car tax BIK rates 2023/24 to 2027/28
Every UK company car has a BIK rate band based on its CO2 emissions and zero emission miles.
To calculate your company car tax, you can multiply your car’s P11D value by the BIK rate percentage (see the table below), then multiply that figure by your tax band i.e. 20% or 40%.
