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 requre business licenses and some do not. Your city clerk can tell you if you need one. 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.
