FAVR Car Allowance vs Cents-Per-Mile

From time to time, we like to feature a question we have received. This time, the question is about whether a fixed and variable rate reimbursement (aka FAVR car allowance) is superior to a cents-per-mile reimbursement rate.

What are the advantages of FAVR vs. a cents-per-mile reimbursement?

That's the essence of the question being asked below. But here's the full question so you get a sense of the company's situation:

Q: Our company has a couple hundred employees driving their own vehicles for business. We are currently reimbursing them for business mileage using the IRS mileage rate. The company cents-per-mile rate makes sense, so why bother with a more sophisticated program like fixed and variable rate reimbursement?

In answering this question, we first clearly distinguished between the two types of programs. So let's define and describe each one in turn.

Company mileage rate, or "cents-per-mile"

In a standard reimbursement program, management selects a cents-per-mile rate for employees, who then report business miles. Your organization elected to use the IRS standard business rate. This reimbursement rate remains the same for all mobile employees no matter their actual business costs, their vehicle choice, or their business mileage amount.

The IRS mileage rate is a tax tool that typically only changes at the beginning of each calendar year, though there have been times (such as in 2022) in which the rate was adjusted mid-year. (The IRS standard business rate for 2024 is 67 cents per mile.)

The objective of this type of program is simplicity – one rate fits all, and the system of reimbursement is straightforward. Employees log trips and mileage in a spreadsheet or mileage app, submit totals, and receive the amount equal to their mileage multiplied by the rate.

But simplicity comes with a downside. Not all mobile employees actually experience the same costs, so a standard cents-per-mile rate can overpay some while underpaying others. Also, it’s important to remember that the IRS mileage rate is not designed for individual reimbursements but for tax deductions in lieu of itemizing business vehicle expenses.

Fixed and variable rate (FAVR) car allowance

The fixed and variable rate allowance is an IRS procedure that considers all reimbursements as non-taxable expenses as long as guidelines are followed. This means your car allowance is not taxed as compensation. Unlike the IRS mileage rate, FAVR was designed to be a corporate business tool, not a personal tax tool.

Fixed and variable rate payments consist of two components: a fixed monthly dollar amount and a variable reimbursement rate.

To calculate the appropriate fixed and variable rates, management, with the assistance of mBurse, selects the program parameters and standards for the business vehicle program based on needs that are unique to your company. mBurse’s extensive databases for business vehicle costs are then used to generate suitable reimbursement rates.

The fixed dollar amount is used to address the fixed aspects of reimbursable costs (insurance, license, taxes, depreciation). However, while these costs may remain relatively stable for a single employee, they can vary between different employees working in different locations. Consequently, the dollar amount may vary by employee based on their zip code. 

Similarly, the variable rate is location-sensitive, taking into account cost differences between different territories. Paid as a cents-per-mile reimbursement, this rate rises and falls with fuel prices, and is used to address fuel and other mileage-based costs (maintenance, oil, and tires).

As with a standard mileage rate, drivers report mileage for reimbursement. The big difference is that a FAVR rate can vary over time and by location, unlike the IRS rate, which remains the same for everyone during the year.

Why FAVR car allowances are superior to cents-per-mile reimbursements

Overall, FAVR is a more accurate and sophisticated reimbursement program based on the company’s objectives, whereas the IRS mileage rate is a tax tool. A standard cents-per-mile rate is simple and convenient but too static to accurately and equitably reimburse employees.

When a company selects a third-party administrator like mBurse to develop a fixed and variable rate reimbursement program, the management enhances its ability to align reimbursement with company objectives. Management gets to set standards for vehicle use that reflect company priorities and build around these standards.

The IRS mileage rate represents the average costs of owning and operating motor vehicles, based on last year's average costs. A company adopting a fixed and variable rate vehicle reimbursement program can instead develop its reimbursement standards based on the current actual costs of owning and operating the type of vehicle most suitable to its work requirements – in the locations where employees actually operate.

Management also establishes the level of insurance coverage employees must carry to mitigate business risk and factor that expense into the reimbursement. The company can even set parameters around vehicle age, especially if image is important, and reimburse based on the expected age of the vehicle.

FAVR puts employer goals and employee needs first

Rather than starting with the reimbursement rate and applying it to all employees indiscriminately, the fixed and variable reimbursement rate approach allows management to build the program around company priorities and employee needs. 

The ultimate goal of a FAVR program is an equitable, defensible reimbursement that is accurate and keeps up with current costs. By choosing FAVR, you choose a fairer approach that will over time promote good morale and help you retain valued employees.
