Arizona does not require that employees are reimbursed for their mileage. However, if an employer chooses to reimburse their employees, the standard rate in Arizona is about 0.555 cents per mile.
Employee mileage reimbursement is usually a rate paid per mile. Multiply the amount of miles by the rate paid per mile to arrive at employee reimbursement. If an employee is paid 20 cents per mile, for example, and the employee drives 40 miles, then the reimbursement fee would be $8. 00.
In California 50.5 cents per mile.
