If your employer provides you a company car, petrol card and/or car driver, you will notice that an amount will be treated as Benefit-In-Kind (BIK) in your EA Form, which is taxable.
The following table shows how the value of such taxable BIK value is calculated.
For example, if you are provided with a Honda Accord 2.4 which its cost is fall under the range of RM150,001-RM200,000, and you are also provided with a petrol card but no driver, your taxable BIK income will be RM7,000 + RM1,800 = RM8,800.
If your tax rate is 27%, then you will need to pay RM8,800 x 27% = RM2,376 for this BIK in your income tax. (Note: the maximum personal income tax rate will be reduced to 26% from assessment year 2010 onwards.)
This amount is normally already divided and deducted in your monthly PCB deduction.
