What Is and Is Not Taxed in Wyoming
Unprepared groceries are exempt from Wyoming state sales tax — prepared food and food sold with eating utensils is taxable.
Prescription medicines are exempt in Wyoming, as they are in every state that levies a sales tax; over-the-counter drugs and most medical supplies are treated separately and are frequently taxable.
Out-of-state sellers must register and collect Wyoming tax once they cross the state's economic nexus threshold, a rule that follows from the 2018 Supreme Court decision in South Dakota v. Wayfair. Below that threshold, the buyer technically owes use tax instead.
