Frequently Asked Questions
Q: How long does it take to receive a Business Registration Certificate?
A: A Business Registration Certificate will be mailed to the mailing address on file within ten (10) business days of the starting date indicated when the business was registered with the Office of the Treasurer & Tax Collector. In the event that the business owner needs the certificate sooner, a temporary certificate can be requested.
Q: How long does my registration last? Do I need to renew my registration?
A: The business registration certificate is issued on a yearly basis. The one-year registration period is based on San Francisco's fiscal year calendar which begins on July 1 and ends June 30th of the following year. Every year thereafter, the Business Tax Registration Certificate is renewed each year in February for the following full fiscal year.
Q: What is the fee for the Business Registration Certificate?
A: For new businesses, the first year's registration fee is based on the tax due on its estimated payroll expense liability as reported on the Application for Business Tax Registration. The tax rate on payroll expense is 1.5%. Businesses that hire employees to perform work or render services within San Francisco pay registration fees based upon their total payroll expense attributable to San Francisco.
