Thinking about setting up a FAVR solution for your team? This can be a powerful method to provide fair, tax-free reimbursements, but it only works if you follow the IRS’s rules.
The IRS lays out specific conditions that both the program setup and the employees covered under it must meet. None of these are optional, and if you get the structure wrong, you’ll risk your employee reimbursements becoming taxable, or worse - your program may not qualify at all.
Here’s everything you need to know about the IRS’s FAVR guidelines for 2026.

IRS FAVR Requirement #1: Standard Automobile Cost Limit
Every FAVR program is built around a standard automobile, which is the vehicle a business uses as the basis for calculating the allowance. For 2026, the IRS caps the maximum standard automobile cost at $61,700.
If the vehicle you’ve chosen as your standard costs more than that limit, the program will be outside the IRS’s framework. This is one of the first things to verify when designing or updating a FAVR system.
IRS FAVR Requirement #2: Minimum Covered Employees
FAVR isn’t designed for very small teams. The IRS requires that at least five employees are covered under the plan at all times throughout the year.
There’s also a restriction on the mix of those employees. A majority of covered employees can’t be management employees at any point during the year.
Control Employee Restriction
The IRS does not allow a FAVR allowance to be given to a control employee. This is a separate rule from the management employee limitation.
A control employee tends to be a high earner or someone high up in the company, such as a board member or a major owner.

IRS FAVR Requirement #3: Driver Mileage Threshold
FAVR is designed for employees who genuinely drive significant miles for work. To stay within the IRS guidelines, your employees must drive and substantiate at least 5,000 business miles for the calendar year, or, if greater, 80% of the annual business mileage your FAVR plan assumes.
If an employee is only covered for part of the year, these thresholds can be prorated monthly. That said, FAVR generally isn’t the right fit for occasional or low-mileage drivers.
IRS FAVR Requirement #4: Vehicle Requirements
An employee must own or lease the vehicle being reimbursed. In the first year an employee receives a FAVR allowance for a particular vehicle, that vehicle’s original cost as a new vehicle must be at least 90% of the standard automobile that you set up in your plan.

In addition, the vehicle’s model year can’t differ from the current calendar year by more than the number of years in the retention period (and that retention period must be at least two years). Essentially, the employee’s vehicle has to reasonably align with the type of car the plan is based on.
IRS FAVR Requirement #5: Mileage and Business Use
The IRS doesn’t allow employers to use arbitrary assumptions when building out FAVR rates. Annual business mileage used in the plan can’t be less than 6,250 miles, and the business-use percentage can’t exceed 75%.
The IRS also defines mileage bands that correspond to maximum business-use percentages, so the assumptions baked into the plan need to reflect what employees are actually expected to drive.
IRS FAVR Requirement #6: Documentation and On-Going Management
A properly labeled FAVR plan isn’t automatically tax-free. FAVR still requires accountable plan-style administration and reliable substantiation.
Employers need to maintain written records supporting the cost data and assumptions used to build the allowance. Employees must also provide vehicle and insurance information when a vehicle is first covered and again as required in future years.

That typically includes the vehicle’s make, model, year, odometer reading, insurance coverage details, and purchase/lease information - and these records are to be maintained over time.
Note that certain payments made under FAVR can still be taxable. For example, optional high-mileage payments are treated by the IRS as wages subject to withholding and employment taxes.
IRS FAVR Requirements Frequently Asked Questions
What is the 2026 FAVR standard automobile cost limit?
For 2026, the IRS maximum standard automobile cost for a FAVR plan is $61,700. If your chosen vehicle’s cost exceeds this amount, your program will fall outside the IRS framework.
Can a small company use FAVR?
Not very effectively in most cases. The IRS requires at least five covered employees at all times during the year, which rules out most very small or executive-only programs.
Is FAVR reimbursement always tax-free?
FAVR is not tax-free automatically. A well-structured FAVR system can support tax-free reimbursements, but certain payments (like optional high-mileage payments) are still treated as taxable wages.
What happens if an employee doesn’t hit the mileage requirement threshold?
If an employee doesn’t substantiate the required minimum business miles, they can’t be treated as covered under the FAVR safe harbor for that period. Employers typically handle this by switching the employee to a different reimbursement method (such as cents-per-mile) for that time.

IRS FAVR Requirements: In Conclusion
FAVR can be a great reimbursement method for the right team, but the IRS rules aren’t suggestions.
Staying compliant - and tax-free - requires choosing the right standard automobile, covering enough eligible employees, ensuring drivers hit mileage thresholds, and more.
