What is foreign qualification?
A company is “domestic” in the state where it was formed and “foreign” everywhere else. Before it does business in another state, that state usually expects it to register — to qualify as a foreign entity. The company is not re-formed: it keeps its home-state charter and its home-state law. The new state records it, requires an agent there to receive legal papers, and from then on expects its local filings.
The words vary. Texas and Delaware call it a registration, Florida a certificate of authority, New York an application for authority. The forms vary too, and so does the entity type: an LLC and a corporation file different applications in the same state. Each state guide below names the form for a foreign LLC and the separate one for a corporation.
When is foreign qualification required?
When the company does business in the state as that state defines it. No single national test exists, and some states leave the phrase undefined. Texas says, generally, that a foreign entity is transacting business there if it has an office or an employee there or is otherwise pursuing one of its purposes there. California looks for repeated and successive transactions inside the state, other than interstate commerce. New York and Delaware simply require it before doing business, and both publish lists of activities that do not count.
Those lists tend to share a pattern: holding meetings, keeping bank accounts, defending a lawsuit, selling through independent contractors and a single isolated transaction usually do not require qualification on their own. An office, staff, property you operate or a steady flow of in-state contracts usually does. Filing offices do not give opinions on a particular company, so if it is borderline, ask your counsel — and qualify before the activity starts rather than after.
