Registering Your Business
Business Registration
Every person or entity doing business in the City and County of San Francisco must possess a valid Business Registration Certificate from the Office of the Treasurer & Tax Collector, as stated in Article 12A of the San Francisco Business and Tax Regulations Code. This Code also applies to businesses located outside of San Francisco that perform business transactions or services in San Francisco.
- Business Registration Certificates are issued on an annual basis and are valid for the City's fiscal year calendar, beginning on July 1, and ending June 30 of the following year.
- New business owners must register for their initial certificate within 15 days of conducting business.
- Existing business owners must renew their registration each year by the deadline of February 28 (or February 29 during leap years) for the upcoming fiscal year starting July 1.
All businesses are required to file a Payroll Expense Tax Statement for their business annually by February 28 for the prior calendar year (January 1 - December 31) and must also renew their Business Registration Certificate for the next fiscal year (July 1 - June 30) if they plan to conduct business within the new fiscal year.
