The car benefit is calculated by multiplying the car's list price, when new, by a percentage linked to the car's CO2 emissions.
For diesel cars generally add a 4% supplement (unless the car is registered on or after 1 September 2017 and meets the Euro 6d emissions standard) but the maximum is still 37%.
The list price includes accessories.
The list price is reduced for capital contributions made by the employee up to £5,000.
Special rules may apply to cars provided for disabled employees.
For cars registered before 1 January 1998 and cars with no agreed CO2 emissions the charge is based on engine size.
Car fuel benefit applies if an employee has the benefit of private fuel for a company car.
The benefit is calculated by applying the percentage used to calculate the car benefit by a 'fuel charge multiplier'.
The charge is proportionately reduced if provision of private fuel ceases part way through the year. The fuel benefit is reduced to nil only if the employee pays for all private fuel.
Fuel charge multiplier: £23,400 (2017/18: £22,600)
Van benefit is chargeable if the van is available for an employee's private use.
A fuel benefit may also be chargeable if an employee has the benefit of private fuel paid for in respect of a company van.
The charges do not apply to vans if a
'restricted private use condition' is met throughout the year.
A reduced benefit charge may apply to vans which cannot emit CO2 when driven.
Fuel benefit: £633 (2017/18: £610)
Advisory rates only apply where employers reimburse employees for business travel in a company car or require employees to repay the cost of fuel used for private travel in a company car. If the rate paid per mile of business travel is no higher than the advisory rate for the particular engine size and fuel type of the car, HMRC will accept that there is no taxable profit and no Class 1 NIC liability.
Mileage Allowance Payments (MAPs) represent the maximum tax free mileage allowances an employee can receive from their employer for using their own vehicle for business journeys.
An employer is allowed to pay an employee a certain amount of MAPs each year without having to report payments to HMRC.
If the employee receives less than the statutory rate, tax relief can be claimed on the difference.
