California Mileage Reimbursement

California sets strict labor laws, ensuring that employees are reimbursed for any expenses they incur while on duty. 

One of these expenses is using one’s personal vehicle for business-related purposes.

California law that stipulates mileage reimbursement

The law states that “an employer shall indemnify his or her employee for all necessary expenditures or losses incurred by the employee in direct consequence of the discharge of his or her duties, or of his or her obedience to the directions of the employer, even though unlawful, unless the employee, at the time of obeying the directions, believed them to be unlawful.”

In line with the set labor laws, mileage reimbursement in California is mandatory - employers must pay out mileage reimbursement in order to be compliant.

One of the most common mileage reimbursement programs is the cents per business mile rate, due to its administrative simplicity. Employees are reimbursed at a flat rate per mile and receive the payout each month. In most cases, the mileage reimbursement is not taxed, as it is not considered a benefit.

The IRS sets standard mileage rates each year. Employers are not required to provide the official rate - they can choose to pay out a lower or higher rate per mile. If you are reimbursed at a rate higher than the official, the excess will be taxed as income.

Mileage record requirements

Depending on the method by which employees are reimbursed, employers may require different records. Some common records will include the miles an employee has driven for business purposes and the date and destination of each trip. If your employer reimburses mileage by the actual expenses method, they will also ask for receipts for car expenses. You will still need to record your mileage in order to work out the business use percentage of the vehicle. Learn more about the IRS mileage log requirements.


The standard mileage rate set by the IRS, applicable in California, is 67 cents per business mile from January 1st, 2024. The 2023 mileage rate is 65.5. cents per business mile.
To calculate your mileage reimbursement, simply multiply your business miles by the mileage rate your employer reimburses you at. For example, if you drove a total of 500 miles during December 2023, and your employer uses the standard mileage rate set by the IRS, your calculation will be the following: 500 miles x 65.5 cents per mile = $327.5 mileage reimbursement.
