Employers that provide vehicles to employees must determine the value of any personal use of those vehicles for tax purposes. Personal use of an employer-provided vehicle is generally a taxable fringe benefit and must be included in the employee's wages unless a specific exclusion applies.
Valuation Rules for Employer-Provided Vehicles
General Valuation Rule
Under the General Valuation Rule, the value of personal use is based on the vehicle's fair market value (FMV). FMV is the amount an individual would pay to lease the same or a comparable vehicle under similar terms and conditions in the same geographic area.
Cents-Per-Mile Rule
Employers may use the Cents-Per-Mile Rule if the vehicle meets the applicable IRS requirements, including vehicle-use and valuation requirements. Under this method, the value of personal use is determined by multiplying the personal miles driven by the IRS standard mileage rate in effect for the year. Business miles may qualify as a working condition fringe benefit and may be excluded from wages if properly substantiated.
Lease Value Rule
Under the Lease Value Rule, employers use the vehicle's Annual Lease Value (ALV) from the IRS annual lease value table to determine the value of personal use. If the vehicle is available for only part of the year, the lease value may be prorated. Any substantiated business use may be excluded as a working condition fringe benefit.
Commuting Rule
Employers may use the Commuting Rule to value an employee's commuting use of an employer-provided vehicle at $1.50 for each one-way commute if all IRS requirements are met. Generally, the vehicle must be provided for bona fide noncompensatory business reasons, the employer must require the employee to commute in the vehicle, personal use must be limited to commuting and de minimis personal use, and the employee must not be a control employee.
Unsafe Conditions Commuting Rule
Transportation provided because of unsafe conditions may also be valued at $1.50 per one-way commute if the applicable IRS requirements are satisfied. The rule applies only when transportation is provided due to unsafe conditions and all restrictions on personal use are met.
Exclusions from Wages
Working Condition Benefits
Business use of an employer-provided vehicle may qualify as a working condition fringe benefit and is generally excluded from wages if the expense would have been deductible by the employee as a business expense had the employee paid it directly. The employee must adequately substantiate the business use, including the mileage, time, place, and business purpose of each trip.
Qualified Nonpersonal Use Vehicles
The value of the use of a qualified nonpersonal use vehicle is generally excluded from wages. Qualified nonpersonal use vehicles include vehicles that, because of their design, are not likely to be used more than minimally for personal purposes, such as certain police vehicles, ambulances, qualified delivery trucks, and certain farm vehicles.
Qualified Transportation Benefits
Qualified transportation benefits may be excluded from an employee's wages up to the applicable monthly IRS limits. These benefits may include:
- Commuter highway vehicle transportation between home and work
- Transit passes
- Qualified parking
Employers should use the IRS inflation-adjusted limits applicable for the tax year when determining the amount that may be excluded.
Reporting and Withholding
Employers generally must include the taxable value of personal use of an employer-provided highway motor vehicle in the employee's wages for federal employment tax purposes.
Employers may elect not to withhold federal income tax on the value of the personal use of the vehicle. However, Social Security tax, Medicare tax, and any applicable additional Medicare tax requirements continue to apply.
To make this election, the employer must notify the employee in writing by January 31 of the year for which the election applies, or within 30 days after the vehicle is first provided to the employee, whichever is later.
The taxable value of the fringe benefit is generally reported as wages on Form W-2, including Boxes 1, 3, and 5. Employers may also report the value in Box 14 for informational purposes.
