Why Reimbursement with the IRS Mileage Rate Is Wrong for Many Workers

If your company uses the IRS business mileage rate to reimburse employees, you are using the wrong tool for the task. This vehicle reimbursement approach has significant shortcomings in a normal year, but the unique challenges of the pandemic have exposed these shortcomings further. Let's look at three key reasons to avoid mileage reimbursement at the IRS rate.

What is the IRS Business Mileage Rate?

The 2022 IRS business mileage rate is 58.5 cents per mile. But there's more to it than that. Many people do not know that the IRS mileage rate is a tax deduction tool for individual taxpayers – not a business reimbursement tool. Using it for mileage reimbursements will over-reimburse high mileage travelers and under-reimburse low mileage travelers.

Using the IRS rate for business mileage reimbursement works in certain situations, particularly if all the employees experience similar geographic costs and drive similar mileage amounts. But often drivers experience very different costs and accrue different mileage amounts, especially within companies with employees covering different regions and different territory sizes. Under these circumstances, you need a customizable rate to deliver accurate and equitable reimbursements.

How is the IRS mileage rate calculated?

The IRS mileage rate in any given year is derived from the average costs of vehicle ownership and operation for the previous year across the entire United States. The previous year's circumstances can differ greatly from the current year's. Gas prices in 2021 were a lot higher than they were in 2020,  with high prices expected to continue throughout 2022.

It is this wide variation between average expected costs and actual experienced costs that makes the IRS rate unsuitable in most cases as a vehicle reimbursement. With so many people working from home and conducting virtual meetings with clients, organizations paying mileage reimbursements need a much more flexible approach to offset employees' vehicle costs.

This is especially important for low-mileage drivers, whose fixed vehicle expenses may exceed their reimbursement in the months they drive few miles. It is also important for companies with high-mileage drivers, who likely cost their employers beyond what they actually need for reimbursement.

3 key needs for vehicle reimbursement rates

Let's explore further the problems with using a standard mileage rate for business reimbursements and how to address these in 2022. 

1. Flexibility – the IRS mileage rate is too standardized

An urban driver in California will experience different vehicle costs than a rural driver in Arkansas. That California driver will experience costs much higher than average. Because that driver covers an urban territory, his or her mileage will be lower than average, even though the hidden costs of driving in stop-and-go traffic will add up. Using a standardized mileage rate will fall short of the vehicle expense need. Insufficient reimbursement is actually illegal in California and a few other states.

If the same company employs both the California driver and the Arkansas driver, the company needs to pay them different rates to avoid inequitable reimbursements. Even if a driver is driving far less than in previous years as a result of remote work, some vehicle reimbursement is still owed because the company expects that employee to maintain his or her vehicle and keep the insurance current so the vehicle is available when face-to-face meetings or other business trips are necessary.

2. Accuracy – only a data-driven reimbursement rate is best

The reason the IRS mileage rate under-reimburses low-mileage drivers and over-reimburses high-mileage drivers has to do with the fixed costs of vehicle ownership. These costs include insurance, license, taxes, and depreciation. Because the employer requires the employee to use a personal vehicle for work, the employer is obligated to offset not only the mileage-based costs of business travel, but also the business portion of the costs of ownership.

When a reimbursement is based entirely on mileage, an employee has to drive a certain number of miles to recover these fixed costs, and then an additional number of miles to recover the operational costs. And typically insurance and depreciation account for 60% of the annual cost of a vehicle. In a state like Michigan, which has very high auto insurance rates, that percentage could be even higher.

For drivers with small, expensive territories and drivers forced to work temporarily from home, a mileage-based reimbursement will not accurately cover costs. The same employer could simultaneously be overpaying an employee with a large but inexpensive driving territory, racking up lots of miles with much lower per-mile costs. This company instead needs a reimbursement approach that takes fixed costs into account regardless of mileage, along with vehicle cost data specific to particular regions.

3. Simplicity – the only positive of the IRS mileage rate

When businesses choose to reimburse using a mileage rate, they do it for the simplicity of the system. However, with that simplicity come a lot of problems with inequities between employee reimbursements, inability to adjust with changing times, and inaccurate payment amounts.

But simplicity is important, especially when the expense needs of employees keep fluctuating. No one wants their managers or drivers spending hours trying to calculate individualized reimbursements based on different workers' driving circumstances.

One way to attain simplicity without sacrificing accuracy and flexibility is to outsource vehicle reimbursements to the experts and let them use the latest vehicle cost data and technology to customize and administer vehicle reimbursements. Under this system, known as a FAVR vehicle plan, all the employees would have to do is use a mileage tracking app to record their business mileage, and third-party software would do the rest in supplying their accurate reimbursement.

Flexibility, accuracy, and simplicity for vehicle reimbursements

To achieve the three key needs of today's vehicle reimbursements, the process is straightforward. You start by choosing a standardized vehicle instead of a standardized rate to determine reimbursements. A third-party partner uses current data for that standard vehicle to derive localized rates for each employee, including both the fixed costs of ownership and the mileage-based costs. 

If the employee barely drives one month, that employee still gets reimbursed for the fixed costs. If the employee drives a lot in that month, the employee gets reimbursed accurately rather than overpaid. Like the IRS rate, this reimbursement approach is tax free. Implementing an IRS accountable plan that was designed for business vehicle reimbursements instead of for personal tax deductions is the way to go.
