Different licenses may be needed for different business types or professions. For example, a plumber or a cosmetologist needs a professional license in Idaho, but a retail store does not. Some municipalities require business licenses and some do not. Your city clerk can tell you if you need one. (Idaho does not have a state business license requirement.) We are here to help you sort through the licenses and permits (such as a sales tax permit) you may need.
Note that licenses differ from the type of legal entity you choose for you business (e.g. LLC, sole proprietor, C Corp). You need to first register your entity type with the Idaho Secretary of State before you apply for licenses and permits.
