Additional information or instructions:

California hotels may charge an occupancy tax and this tax is determined by each county, not the state. Please visit the county's website prior to traveling for more information.

Part (a) of California Regulation 1614 clarifies California's policy on CBA and IBA tax exemption: 

"Where payment for tangible personal property sold or consumed in this state is made partly by the United States or its instrumentality and partly by nonexempt persons, the payment is exempt to the extent of the United States' or its instrumentality's share provided it is made directly to the vendor by the United States or its instrumentality. If the nonexempt party makes full payment and then seeks reimbursement from the United States or its instrumentality, the entire amount is taxable even though the United States or its instrumentality may reimburse the party in full or in part."

Are surcharges allowed in this state?
California has a law, California Civil Code section 1748.1, that prohibits retailers from adding a surcharge when a consumer chooses to use a credit card instead of paying by cash. In March 2015, a federal court found the statute unconstitutional and prohibited the Attorney General from enforcing it. The Office of the Attorney General believes that this decision is incorrect and has appealed that order. However, as of now, the Attorney General cannot enforce the statute.  Therefore, vendors can charge surcharges in California.
