Oakland based businesses should obtain Zoning Clearance prior to applying for a Business Tax Certificate. If you are a seller of wholesale or retail goods, you are required to apply for a California Seller's Permit. Both the Seller's Permit and the Zoning Clearance should be listed on the Business Tax Application.

Application Process
Once your application is accepted and processed, you will receive an email verifying our receipt of your application, including the amount due and instructions on how to pay online. You can pay by Mastercard, Visa, Discover Card or an ATM/Debit Card. You will receive an emailed containing your certificate from the Business Tax Office within 5 days. Please make sure to check your spam/junk email folders.

Business taxes must be paid annually, on or before March 1st of each year. It is your responsibility to renew your certificate on time and/or to notify the Business Tax Office if you have not received your annual renewal declaration(s).
