California Code, Business and Professions Code - BPC § 16001.8

(a) A veteran who is honorably discharged or honorably relieved from the Armed Forces of the United States and is a resident of this state shall not be required to pay any local business license fees for a business selling or providing services if the veteran is the sole proprietor of the business.

(b) The Legislature finds and declares that the prohibition on the imposition of local business license fees on veterans as specified in this section is a matter of statewide concern and is not a municipal affair, as that term is used in Section 5 of Article XI of the California Constitution. Therefore, this section applies to all cities, including charter cities.
