Business Tax Application – San Diego, CA

The Business Tax Application is the City of San Diego form used to register a business and request a Business Tax Certificate, the document the city issues instead of a business license once the business tax has been paid.\n\nThe City of San Diego states that issuing the certificate acknowledges payment of business taxes. Applications go to the Business Tax Program of the Office of the City Treasurer, and the form is listed with other resources of the City of San Diego Development Services Department.\n\nThe certificate is a tax registration, not a permission to operate in every respect. The city says it does not authorize any illegal or unlawful business, or any activity that requires a license or permit under state law, county ordinance or the San Diego Municipal Code. Examples the city names include police, health, zoning, planning, building and engineering permits and state contractors licenses. Holding a certificate does not relieve an owner or operator of obtaining those.\n\nThe city publishes two documents next to the application: the Business Tax Application Instructions and a Spanish version of each, titled Solicitud De Impuestos Comerciales and Instrucciones para la Solicitud De Impuestos Comerciales. Businesses also self-certify that the business is allowed in the zone that applies to the property where it will operate.

All businesses operating in the City of San Diego are required to register for a Business Tax Certificate, so the owner or operator of a business located or operating in the city files this application.\n\n- New businesses register to obtain the certificate; the city sets late fees for applications received 15 days after the business start date.\n- Businesses of any size apply, but the city notes that a larger business tax applies to businesses with 13 or more employees, and that the city notifies you by mail if that or other taxes or fees are due.\n- Businesses needing a police business permit use the city's in-person appointment option for new Police Business Permits and renewals, which the city lists alongside business tax registration.\n\nThe certificate is not a substitute for other approvals. If your activity requires a permit or license under state law, county ordinance or the San Diego Municipal Code, you must obtain it separately. The city's page does not describe a separate process for someone filing on another person's behalf, so confirm that by calling the Business Tax Program.

Register as soon as the business starts operating in the City of San Diego: the city assesses late fees on applications it receives 15 days after the business start date.\n\nThe city asks you to allow up to two weeks to receive the Business Tax Certificate. It notifies you by mail if more is due or needed, for example Business Improvement District Assessments, the larger business tax for businesses with 13 or more employees, late fees, or additional information.\n\nOnline applications can be submitted 24 hours a day, every day, once you have registered a username and password. The city's page sets no other deadline for the application itself.

The City of San Diego accepts Business Tax applications electronically, by mail or in person.\n\n- Online: applications can be submitted 24/7 through the city's Business Tax online service.

Accepted payment types are credit card (MasterCard, Visa), ACH checking and ACH savings.\n- By mail: include a check made payable to City Treasurer and send the application to: Office of the City Treasurer, Business Tax Program, PO Box 122289, San Diego, CA 92112-2289. A fee is assessed on mailed applications; the city's page lists the amount, and you can confirm it with the Business Tax Program.\n- In person: schedule an appointment for in-person registration of a Business Tax account, new Police Business Permits and renewals.\n\nFor questions, call 619-615-1500 or email [email protected].
