Vehicle Age Compliance

FAVR vehicle age compliance is a requirement that a driver’s vehicle must fall within a defined age range to qualify for fully tax-free mileage reimbursement.

In Fixed and Variable Rate (FAVR) programs, this is determined by the retention cycle, which represents how long a vehicle is expected to be owned. To remain compliant, a driver’s vehicle cannot exceed this defined age threshold.

If a vehicle is older than the retention cycle, the driver is considered out of tax compliance. When that happens, their reimbursement may be subject to the taxable income test, meaning a portion of the payment could become taxable.

This rule helps keep reimbursements aligned with real-world costs. Since FAVR uses a standard vehicle profile rather than each driver’s actual vehicle, older vehicles with lower ownership costs could otherwise lead to over-reimbursement if no limits were in place.

Maintaining vehicle age compliance helps ensure reimbursements remain accurate, consistent, and aligned with IRS rules.
