The City of San Mateo Municipal Code requires all persons or businesses doing business in the City of San Mateo to pay an annual business tax (also sometimes called a business license). The payment of this tax is required prior to the commencement of business in San Mateo.
After payment of the annual business tax is made, the business will receive a business tax certificate by mail which evidences that the applicable tax has been paid for the period indicated on the certificate. This certificate must be displayed conspicuously in the place of business.
The business tax certificate does not indicate clearance or approval for zoning, fire code, occupancy, or any other City, County, State or Federal permit or license which may be required. It is the responsibility of the business to ensure that it is in compliance with all legal requirements.

State Mandated Disability Access and Education Fund
On September 19, 2012 Governor Brown signed into law SB 1186 which adds a state fee on any applicant for a local business tax certificate, or renewal thereof. Beginning January 1, 2013 the fee is $1.00, followed by an increase on January 1, 2018 to $4.00 and a reduction to $1.00 on January 1, 2024. The purpose of the fee is to increase disability access and compliance with construction-related accessibility requirements and to develop educational resources for businesses in order to facilitate compliance with federal and state disability laws, as specified.
Under federal and state law, compliance with disability access laws is a serious and significant responsibility that applies to all California building owners and tenants with buildings open to the public.
