Mileage Reimbursement In California

It’s legally required in California for companies to reimburse business mileage for their employees as of 2023. Not all states require reimbursement for business mileage, making California an employee-friendly state for work travel and helping to ensure proper business expense compensation. According to California Labor Code Section 2802(a), employers must reimburse their employees for reasonable and necessary expenses to perform job-related duties. [1]

As of 2023, the standard mileage rate set by the IRS is 65.5 cents per mile. However, there are also different rates for charitable organizations and qualified active-duty Armed Forces members traveling for medical or moving purposes. The standard mileage rate for business use can include driving to meetings, site visits, and other work travel as stipulated by the IRS. Note that the IRS does not consider commuting from a home residence to the workplace a business expense. [2]

The IRS standard rate is the maximum amount that can be reimbursed to drivers tax-free, assuming other regulations are followed and detailed recordkeeping is performed. Companies can choose to reimburse their employees above the IRS standard rate, but any reimbursement amount beyond the IRS standard rate may be subject to income tax.

What’s On The Horizon For Drivers

As discussed above, California does not set its own state-wide mileage rate, and drivers follow the IRS-set standard rate. It’s expected that the IRS will set a new rate in early 2024, and it’s vital for employees and employers to keep an eye out for the established rate to understand how to reimburse business mileage adequately. 

The IRS standard rate typically increases or decreases by a few cents, and it’s expected to shift slightly in 2024. Standard mileage rates are usually updated and published yearly, although sometimes they are updated more frequently.

As long as payments don’t exceed the current IRS standard rate and any other relevant requirements are followed, reimbursements can be tax-free.

Beyond expected changes to the IRS standard rate, regulations can change at any time. Both employee drivers and employers need to stay aware of any upcoming changes so they can adjust their vehicle reimbursement program accordingly. 

What This Means For Employees And Employers

For employers with employees who need to drive for work, reimbursement is essential in California. To help ensure compliance with legislation, employers can benefit by setting up a vehicle reimbursement program that accurately tracks all business expenses and reimburses employees accordingly. 

Within the context of work travel, this includes tracking all business mileage using a mileage log, a spreadsheet, or a mileage tracking app. Important mileage information must be followed to justify these business expenses to the IRS, including trip dates, miles traveled, destination, and more details.

It’s worthwhile for businesses to examine the options available for reimbursement, such as fixed and variable rate (FAVR) reimbursement programs. These programs consider different business expenses, allowing them to provide a more accurate representation often.

Beyond simply reimbursements for business mileage, FAVR programs consider other costs from business use of a personal vehicle, including insurance, depreciation, maintenance, and more. Compared to other vehicle reimbursement programs like lump sum allowances and Cents per Mile programs, FAVR is more location-specific by accounting for geographic disparities in reimbursements for varying regional expenses. 

For drivers with employees across different states, it’s essential to be aware of the legislation in each region in which drivers work. Know that regional differences exist in insurance rates, fuel prices, etc. Providing your employees with a region-specific reimbursement plan helps make sure that reimbursements truly reflect actual expenses. 

For example, Californians often pay higher-than-average gas prices than other areas in the United States. FAVR can help ensure that payments more accurately represent business expenses. Having business expenses correctly accounted for isn’t just essential in California; it can also help improve employee morale and retention. [3]

Beyond mileage rates, it’s also important for employees and employers to follow any other regulations specific to their vehicle reimbursement program. For example, FAVR reimbursement programs have minimum mileage requirements, car eligibility rules, and more important laws to be aware of.
