Company car tax calculator, on the worked example
£10,200

Each sheet works from what the driver or the fleet manager already holds: the P11D value on the quote, the CO2 figure on the V5C, the fuel type, the driver's tax band, the business miles. Type those in and the appropriate percentage, the cash equivalent, the tax through the code, the Class 1A and the mileage at the advisory rate rework themselves as you go, with no sign-up standing between you and the number. What Pro adds is the fleet behind the sheet, each car and each driver kept with their dates, and the P11D figures worked each April.

Each figure on this page is HMRC's own method applied to the inputs you typed, with the rate and the page it was read from cited beside it and the date it was read. Carbikly publishes no dealer price, no lease quote and no advice on which car to take: the worked example is there to be overwritten with your own list price and band, and the rates are gov.uk's on the date cited.
