Your Guide to Navigating Through Personal Use of Company Car Rules

Do your employees use company-owned or leased vehicles for personal reasons? If so, you need to know how to handle reporting personal use of company car for wage and tax purposes.

Read on to learn:

What is personal use of company car?

Personal use of a company car (PUCC) is when an employee uses a company vehicle for personal reasons. Driving a company vehicle for personal use is a taxable noncash fringe benefit (aka benefit you provide in addition to wages). As a result, you generally must include the value of using the vehicle for personal reasons in the employee’s income and withhold taxes.

If the employee uses the company car strictly for business purposes, treat the usage differently. Business use of a company car is considered a working condition fringe benefit. A working condition fringe benefit means the value of using the vehicle isn’t included in the employee’s income or taxed because the employee needs it to perform their job.

Personal use of company car: Taxable noncash fringe benefit, included in an employee

So, what’s considered personal use of a company car? PUCC includes:

If an employee does use a company car for one of the above purposes, determine its value and include it in the employee’s compensation for tax purposes.

Exceptions

In some cases, an employee’s personal use of a company car is exempt from inclusion in wages and taxes.

De minimis fringe benefits

De minimis means too small for consideration. If an employee’s PUCC is so small that it would be unreasonable or administratively impracticable (e.g., infrequent and brief side trips) to track, you can exclude it.

Qualified nonpersonal use vehicle

If a company vehicle has a special design that makes personal use unlikely, exclude personal use from employee wages.

Qualified nonpersonal use vehicles include:

You can get more information about the qualified nonpersonal use vehicle exception in Publication 15-B.

Demonstration vehicles

Do not include personal use of a demonstration vehicle if the employee is a full-time automobile salesperson or sales manager within the sales area of the dealership.

To qualify for this exception, you must substantially restrict the employee’s PUCC:

Personal use is limited to the greater of either a 75-mile radius of the dealership or the employee’s actual commuting distance.

You can get more information about the personal use exemption for demonstration vehicles in Publication 15-B.

How to calculate personal use of company vehicle value

So, how exactly do you calculate the value of an employee’s personal use of a company car? You can use one of the following methods to determine the value of PUCC:

The general valuation rule is the most commonly used method for determining the value of fringe benefits. However, you can use one of the special valuation rules (cents-per-mile, commuting, or leave value) for determining PUCC value.

Remember not to include the working condition benefit in the PUCC value. Again, working condition benefit is the vehicle use that the employee uses for business reasons.

You can learn more about each of these rules in IRS Publication 15-B.

General valuation rule

Under the general valuation rule, calculate the value of PUCC using the fair market value (FMV).

The PUCC’s fair market value is the price the employee would pay a third party to buy or lease the benefit in the same geographic area and under the same or comparable terms.

Cents-per-mile rule

Under the vehicle cents-per-mile rule, determine the employee use of company vehicle value by using the standard mileage reimbursement rate.

To find an employee’s PUCC value under the cents-per-mile rule, multiply their personal miles driven by the IRS standard mileage rate.

For 2024, the standard mileage rate is 67 cents per business mile drive. The rate includes the costs of maintenance, insurance, and fuel.

To use this rule, you must meet the following conditions:

  1. You expect the employee to regularly use the vehicle for business throughout the year
    1. At least 50% of the total mileage each year must be for business
    2. The vehicle is generally used each workday to transport at least three employees to and from work, in an employer-sponsored commuting pool
    1. The vehicle is driven by employees at least 10,000 miles per year (business and personal combined)
    2. The vehicle is primarily used by employees

    You cannot use the cents-per-mile rule for a vehicle if its value on the first day of use exceeds an amount set by the IRS. These values change every year.

    If you use the cents-per-mile rule for a vehicle, you must use the rule for all following years. However, you can use the commuting rule if the vehicle qualifies. And if the vehicle no longer qualifies for the cents-per-mile rule, you can use another rule.

    Commuting rule

    Does an employee use a company vehicle to commute to and from work? If so, you might opt for using the commuting valuation rule.

    Under the commuting rule, the PUCC value is $1.50 for a one-way commute, per employee. You can use this rule if you:
