If you have the use of a company-owned car for your own private use (and that includes commuting to and from work) then you will be taxed on this ‘benefit’.
The deciding factors on how much tax you pay are the value of the car, its CO2 emissions (the lower these two figures, the less it will cost you) and whether it has a petrol or diesel engine.
Note that the value of the car is not what it actually cost, but the manufacturer’s recommended On-The-Road cost at the time of purchase – less the Vehicle Excise Duty and First Registration Fee. This is known as its P11D value.
The car’s CO2 emissions figure and fuel type are used to decide the percentage of that P11D value on which you will pay tax, click here to view the BiK Bands.
The resulting figure is the Car Benefit Charge. You then pay 20%, 40% or 50% (45% from April 2013) tax on this sum, according to your income tax rate.
Example: Diesel powered car with OTR of £18,000 and CO2 emissions of 110g/km (2012/2013 tax year).
On-The-Road | £18,000.00 |
|---|---|
Higher rate (40%) tax payer | £1180.16 |
Deduct: VED (£0) and First Registration Fee (£55) | |
Effective list price | £17,945.00 |
Add: Optional metallic paint (£495) | |
List price for tax purposes (P11D value) | £18,440.00 |
% of P11D value to be taxed for 110g/km diesel | 16% |
Car benefit charge (P11D value x 16%) | £2950.40 |
Benefit-in-Kind tax liability | |
Basic rate (20%) tax payer | £590.08 |
If your employer provides you with free fuel for private use (which includes driving to and from work), then this is also a taxable benefit.
This is calculated in a similar way to the Car Benefit, except that instead of taking a percentage of the P11D value of the car, the percentage is applied to a flat rate charge of £20,200 (tax year 2012/2013). The BiK Calculator provided will show you the tax due if you select ‘Yes’ to the question ‘Does your employer pay for private use of fuel?’ and whether this will save you money based on your annual personal mileage.
Diesel powered car with OTR of £18,000 and emissions of 110g/km (2012/2013 tax year)
Fuel Benefit flat-rate value | £20,200.00 |
|---|---|
Tax to be paid (40% tax payer) | £1292.80 |
Fuel Benefit Charge (at 16%) | £3232.00 |
Tax to be paid (20% tax payer) | £646.40 |
Note that the figure of £20,200 is used irrespective of the number of private miles you travel.
The table below shows the percentage of the car’s price to be taxed based on CO2 emissions in grammes per kilometre.
