What is your annual fuel cost? Check out our fuel cost calculator.

The system for taxing those who use company cars has seen annual incremental increases in the cost of benefits, while maintaining the basic approach to taxing those who use a company owned vehicle. The basis of the charge is to tax a figure calculated by multiplying the car's list price by an emission-based percentage, with a 3% surcharge on diesel powered cars.

Cars emitting CO2 at a specified level are taxed on rates varying from 9% to 37% of the list price. Emissions for non-diesel driven cars from 0 to 50g/km (this band includes electric cars) are taxed at 9%, from 51-75g/km are taxed at 13% and from 76-94g/km, at 17% of list price.

Cars running solely on diesel fuel are currently subject to a 3% supplement. 

Cars with higher levels of CO2 emission are taxed on a graduated scale rising to a maximum (for both petrol and diesel) of 37% of the car's price. These figures apply to all company cars, including second cars.

CO2 emission information

For all cars first registered from November 2000, the definitive CO2 emissions figure for tax purposes will be recorded on the Vehicle Registration Document (V5).

Older cars

Cars first registered before January 1998, for which there are no reliable CO2 emissions data, are taxed according to their engine size, as follows:

Engine size (cc)    Percentage of car's price charged to tax
0 - 1400 15%
1401 - 2000 22%
2001 and more 32%

Fuel scale charges

Where the employer pays for any fuel used privately by the employee, there is an additional scale charge based on the CO- based car benefit percentage applied to a standard value of £22,600.

Employee contributions

Where the employee is required, as a condition of the car being made available, to pay for the private use of a car, the value of the benefit is reduced accordingly (on a pound for pound basis). Capital contributions of up to £5,000 made by employees towards the cost of the car and/or accessories, when the car is first made available, will reduce its list price for tax purposes.

By contrast it is ‘all or nothing' for the fuel scale charge, which remains at the full value unless the employee pays for all private fuel!

HMRC has published advisory fuel only rates which will be accepted either for employers reimbursing employees for the cost of fuel for business mileage, or for employees reimbursing employers for the cost of fuel for private mileage in a company car. Alternative rates may be negotiated, for example when it is necessary for the performance of his or her duties that an employee uses a four-wheel drive vehicle. In this instance a higher rate per mile might be agreed due to the typically higher fuel consumption

Tax payable

These standard charges are subject to income tax at the basic, higher or additional rate (depending on the employee's rate of pay). The tax is usually collected under the PAYE system by appropriate adjustment of the employee's tax code.

For the benefit to be attractive, the employee must pay less in extra tax than it would cost them to run their own car out of their taxed income. These are examples of the 2017/18 tax costs to an employee of a company car:

Tax free benefits

  • Car Parking

The provision of a car parking space at or near the employee's place of work is not an assessable benefit.

  • Pool Cars

There is no tax for using a pool car. This is one where private use is merely incidental to the business use, and it is not normally used by one employee to the exclusion of all others.

Please note: A pool car must not normally be kept overnight at or near an employee's home.

Business use of an employee's own car

It is quite normal practice for employees to be reimbursed at a reasonable mileage rate for business use of their own cars.

A statutory system of tax and national insurance free mileage rates applies for business journeys in employees' own vehicles, as follows:

Cars and vans
On the first 10,000 miles in the tax year 45p per mile
On each additional mile above this 25p per mile
Motor cycles 24p per mile
Bicycles 20p per mile

It is no longer possible to make a claim for tax relief based on actual receipted bills, nor claim capital allowances or interest on loans related to car purchases.

Note that the lower rate for more than 10,000 business miles only applies to income tax. The national insurance rate remains at 45p for any number of miles.

Unless the employee is reimbursed at a rate higher than the statutory mileage rate, the payments do not need to be reported on a P11D.

Passenger payments

When an employee travelling on business carries fellow employees as passengers he may be reimbursed a further 5p per passenger tax free provided the journey is a business journey in respect of the passengers. No claim can be made if the employer does not make passenger payments.

Company vans

The taxable benefit for the unrestricted use of company vans is £3,230 (with no reduction for older vans) plus a further £610 of taxable benefit if fuel is provided by the employer for private travel. Electric vans are currently taxed at 20% of the van scale rate (i.e. £646).

The tax payable on the use of a company van ranges from £129.20 up to £1,728 p.a., and the employer's Class1A NIC payable ranges from £89.15 to £529.92 p.a.

Tax saving check list

  • Keep adequate records of business mileage.
  • Always check your tax code to see that the correct benefit is being applied.
  • If you have low private mileage, you may be better off if you pay for all your own private fuel.
  • If you have high business mileage, it may be better to use your own car and claim "mileage" from your employer.
  • Encourage your employer to apply for a P11D dispensation.

Company cars - beyond 2017

  • The taxable benefits tables have also been published for the tax years, 2018/19 to 2019/20.
  • These increase the percentages for each band of emissions by 2% and 3% respectively.
