Carbikly

The benefit in kind from the P11D value and the CO2 band, the tax the driver pays on it at their own rate, the employer's Class 1A on the same figure, the advisory fuel rate for the engine, and whether the cash allowance would have left the driver better off. You type the list price, the band, the fuel and the rate; the sheet works HMRC's own steps in front of you and asks for nothing else.

Carbikly is a small piece of software for the people who have to work out what a company car costs in the United Kingdom: the employee offered a car or a cash allowance, the director putting a car through their own company, the fleet or payroll manager reporting the benefit each April. It has two halves. The worksheets are free and work HMRC's steps on the page from what you type: the benefit in kind from the P11D value, the CO2 band and the fuel, the tax the driver pays on it, the employer's Class 1A, the mileage at the advisory rates, and the car set against the allowance. Carbikly Pro is the fleet those figures come from: every car with its list price, band, fuel and dates, every driver with their rate, the figures worked each year and the reminders before 6 July and 22 July, exportable at any time.

Who it is for: Built for UK company cars only: the driver offered one, the director putting one through the company, the fleet or payroll manager reporting it
