Vehicle Benefits

Chargeable on employees earning £8,500 or over (including benefits), and directors.

The tax you pay on your company car is governed by four factors:

  • the list price of the car, on the day before it was first registered, plus certain accessories,
  • the rate at which the car emits carbon dioxide (CO2),
  • the fuel type, (for most types of car, this is all the information you need to work out the taxable benefit)
  • your highest rate of income tax.

You can find your taxable percentage for 2003/04 using the following table:

CO2 Taxable % CO2 Taxable % CO2 Taxable %
in g/km Petrol Diesel in g/km Petrol Diesel in g/km Petrol Diesel
Less than 160 15% 18% 190 to 194 22% 25% 225 to 229 29% 32%
160 to 164 16% 19% 195 to 199 23% 26% 230 to 234 30% 33%
165 to 169 17% 20% 200 to 204 24% 27% 235 to 239 31% 34%
170 to 174 18% 21% 205 to 209 25% 28% 240 to 244 32% 35%
175 to 179 19% 22% 210 to 214 26% 29% 245 to 249 33% 35%
180 to 184 20% 23% 215 to 219 27% 30% 250 to 254 34% 35%
185 to 189 21% 24% 220 to 224 28% 31% 255 and over 35% 35%

How to find out how much CO2 your company car emits – see:
  • the car’s V5 registration document
  • your dealer
  • the data pages of car magazines (current models)

Reliable emissions data is not widely available for cars registered before 1 January 1998. For them, the following taxable percentages apply, regardless of fuel type:

Engine capacity Taxable %
Up to 1400cc 15%
1401 - 2000cc 22%
Over 2000cc 32%

Remember, too, that the rate of the taxable benefit will rise next year - for the comparative rates, simply deduct 10 from all the CO2 figures in the table – and may well rise again in 2005.

If the employee pays for the full cost of all fuel for private journeys (usually including home to work) there will be no car fuel benefit. In all other cases the full tax charge will be due.

The taxable car fuel benefit is, for 2003/04, calculated by multiplying £14,400 by the same percentage as applies (or would apply) for the car benefit.

Example: A company car driver has a car which, on the day before it was first registered, had a list price of £18,000. It runs on petrol, and emits 182 g/km of CO2.

If we assume the driver pays tax at 40%, the annual tax bill on the car is: £18,000 x 20% x 40% = £1,440

If the employer provides any fuel used for private journeys and is not re-imbursed for the cost, the 2003/04 tax bill for the fuel is: £14,400 x 20% x 40% = £1,152.
