Register a Business

San Francisco’s Business and Tax Regulations Code generally requires that every person engaging in business within the City, regardless of whether the business or person is subject to taxation, must register within 15 days after commencing business within the City. Lessors of Residential Real Estate can learn more about information on business registration requirements here. 

In general, businesses must register if any of the below statements are true:

• Maintain a fixed place of business within San Francisco.

A single-member entity (including a single-member limited liability company) treated as a disregarded entity for federal income tax purposes will be disregarded for purposes of the Business Registration requirements.

Business Registration Fees for new businesses are based on San Francisco gross receipts or payroll expense for the current calendar year, and the business activity types selected. Use Schedule B if your business consists solely of the business activities of Certain Services (e.g. Repair/Maintenance, Personal/Laundry, Civic Orgs), Retail Trade, and/or Wholesale Trade (described on page 1 of the Application).  If your business does anything else, use Schedule A.
