Other California local business taxes

Nearly every California municipality imposes some form of local business license tax or fees, but the types of levies, tax bases, and filing requirements and deadlines vary widely by locality. For example, the City of Santa Monica, like its neighbor Los Angeles, imposes a gross receipts tax on businesses operating within the city, but returns and payments aren't due until August 31 of each year.
