General Information

The law provides that a Business Tax Certificate is necessary before any Business, Trade, Profession, Enterprise, Establishment, Occupation, or Calling is conducted within the City. A Tax Certificate is required even though the business may be located outside the City or have a Tax Certificate from another city.

The Business Tax Certificate is valid until December 31st of the year in which it is issued and must be renewed by April 30th of the following year. It is the responsibility of the tax certificate holder to ensure that the tax is paid each year. A change in business name and/or business address requires a new application and fee. For additional information on the City’s Business Tax Certification, please review the Municipal Code Title 3-Chapter 1 here.

California State Mandated Fee of $4.00 for all Business Licenses and Renewal of Business Licenses: California CASP Fee: SB-1186 went into effect 01/01/2013, and imposes, on and after January 1, 2013, and until December 31, 2018, an additional State fee of $1 on any applicant for a local business license or equivalent instrument or permit, or renewal thereof, for purposes of increasing disability access and compliance with construction related accessibility requirements and developing educational resources for businesses to facilitate compliance with federal and state disability laws, as specified.

The Senate Bill 1186 creates a continuously appropriated fund, the Disability Access and Education Revolving Fund, for the deposit of funds to be transferred to the Division of the State Architect. By adding to the duties of a local entity, this bill imposes a State-mandated local program, which results in costs incurred by the local agencies. On October 11, 2017, AB 1379 went into effect and extends the operation of this fee indefinitely and, on and after January 1, 2018, and until December 31, 2023, increases the amount from $1 to $4. The bill would revert the amount of the fee back to $1 on and after January 1, 2024.

The collection of this mandated fee imposed by the State is already included in the business tax registration fee, and the renewal fee of $19.00. For more information on SB-1186 and AB 1379, please visit
