California Labor Code §2802(a) requires for employers to reimburse employees for all business related expenses incurred in performing their duties, such as driving for the benefit of the employer. The Labor Code does not specify when the payment must be made to the employee, however, the California Code of Regulations requires for mileage reimbursement to be paid when wages are paid or at least one paid month. Specifically, the regulations state that:
“[e]mployers shall compute and pay mileage reimbursement when wages are paid, or at least once per calendar month as determined by the employer. All such payments must be made not later than the end of the calendar month following the calendar month in which the expenses were incurred, unless the employee fails to provide the employer with the records of the number of miles driven for the reimbursement period, in which case, the reimbursement must be made no later than the month following the month in which the employee provides the employer with the records for the mileage claimed.” Title 8 of the California Code of Regulations, Section 13701(g).
