Question:  If I form a California limited liability company, can it do business in a state other than California?

 Answer:  Yes.  An LLC formed in any of the fifty states may engage in business in any of the other state if the LLC registers to do business in the other state.  Registering to do business in a state means filing a form and paying an initial registration fee and annual fees each year. If the state where the LLC registers to do business has a state income tax then if the LLC earns income from within the state the LLC must file a state income tax return and pay state income tax to the registration state.
