I need a bit more information in order to analyze which entity is best, but generally speaking an LLC would work well. The tax structure for the LLC would depend upon how much money the business earned, but there is a lot of flexibility with LLCs. You may want both a California LLC and later a Nevada one when you expand, it is best to keep activities in the two states separate. Please give us a call and talk to one of our representatives for assistance with forming the correct entity for your business.
