# Carbikly

> Carbikly is free company car worksheets for the United Kingdom (the employee offered a car or an allowance, the director putting a car through the company, the fleet or payroll manager reporting the benefit): the company car tax calculator working the benefit in kind, the driver's tax and the employer's Class 1A from list price, CO2 band, fuel type and rate; the company car mileage rates worksheet at the advisory fuel rates; the car-against-allowance comparison; and the electric company car mileage rates; plus a paid workspace, Carbikly Pro at £14 a month for the whole fleet, that keeps each car with its list price, CO2 and dates and each driver with their rate, and works the P11D figures each April with reminders before 6 July. It gives no advice on which car to choose and publishes no dealer price: every figure is HMRC's method on the numbers entered.
