Below are links to the secretary of state or business filing office for each state. This is the state office that handles business formation filings, business name searches, annual business filings, and other business-related public matters. You will need to check with this office in the state where you are located or where you do business to find out what business filing obligations you have in that state. This office also serves as a resource for businesses starting or operating in the state and provides helpful information and links to other resources, including licensing, tax filings, and employment matters.
To find other state-specific as well as federal resources, see Nolo's Small Business Resources section.
