Kentucky Taxation for Commuting in Government Leased Vehicle can be broken down into two types: Fringe Benefit and Standard Mileage. The Fringe Benefit Taxation applies to any employee who commutes in a government leased vehicle for work-related purposes. The taxable amount is determined by multiplying the number of miles used for commuting by the IRS standard mileage rate. The taxable amount is then included in the employee's wages, and must be reported on the employee's Form W-2. The Standard Mileage Taxation applies to any employee who uses a government leased vehicle for personal use. The taxable amount is determined by multiplying the number of miles used for personal use by the IRS standard mileage rate. The difference between the total mileage used and the mileage used for work-related purposes must then be reported on the employee's Form W-2. Both the Fringe Benefit and Standard Mileage Taxation require the employee to keep accurate records of the miles used for work-related and personal purposes, and to report them on their Form W-2.
