A sole proprietorship is set up to allow an individual to own and operate a business by him/herself. A sole proprietor has total control, receives all profits from and is responsible for taxes and liabilities of the business. If a sole proprietorship is formed with a name other than the individual’s name (example: John Smith’s Fishing Shop), a Fictitious Business Name Statement must be filed with the county where the principal place of business is located. To determine the applicable county agency where fictitious business names are filed, please refer to the list of California counties provided on the California State Association of Counties website. No formation documents are required to be filed with the Secretary of State. Other state filings may be required depending on the type of business.
