Attention Exhibitors

Every exhibitor is required by the Idaho State Tax Commission to fill out a Form ST-124's Section B (Participant's Information) and Section C (Sales Tax Declaration) for Idaho events.

What is a Form ST-124? IDAHO SALES TAX DECLARATION

Idaho law requires retailers who are "doing business" in Idaho to have a seller's permit and collect sales tax on the sale of goods they ship or deliver to customers in Idaho. All retailers in Idaho must file Idaho sales tax returns to remit the tax they collect. Sales tax applies to the sale, rental, lease or exchange of tangible personal property and some services, including food.
