There are four types of driver reimbursement models: IRS business mileage reimbursement rate, a fixed allowance, the Fixed and Variable Reimbursement Rate (FAVR), and a hybrid model that uses the FAVR guidelines but delivers the driver payment in a cents-per-mile model.
Every reimbursement method factors in five elements: depreciation, insurance, registration, maintenance, and fuel.
The IRS business mileage reimbursement rate is based on an annually study of the fixed and variable costs of operating a vehicle. The current rate as of print time is 53.5 cents per mile.
The other is the monthly fixed rate. The option give drivers a certain a number of dollars which acts as an allowance to operate the vehicles, but if a company is not collecting IRS compliant driver logs, this payment is taxable as income.
Then there’s FAVR, which provides a customized reimbursement rate that is based on individualized costs employees incur each month, and includes geographic and mileage-related cost that consider fuel prices and employees business mileage.
FAVR utilizes a fixed monthly rate for drivers by adding up depreciation, insurance, and registration. The last two are maintenance and fuel costs, with maintenance being broken into three categories: maintenance, tires, and fuel, according to Fournier. Meanwhile fuel costs are factored by zip code.
Lastly, a hybrid model removes the fixed payment of the FAVR program and instead, delivers the payments to the drivers based on zip code locality, but breaks the payment down to a cents-per-mile model. This means drivers that drive more than their FAVR miles would receive higher payments for these miles and conversely, drivers who drive less miles would receive a lower payment. This insures that a company never overpays or underpays a driver and better controls cost, all while maintaining their tax qualified status.
