All drugs for human use, including over-the-counter drugs, are exempt from sales tax even when sold through a vending machine.
To determine if an over-the-counter item is a nontaxable drug, the product label must include a “Drug Facts” panel or a list of active ingredients. For example, eye drops are taxable unless they have an active ingredient or a Drug Facts panel on the label.
Pull-tabs sold through dispensing devices are not subject to sales tax. For more information on taxes that apply to gambling devices, contact the Special Taxes Division of the Minnesota Department of Revenue at 651-297-1772.
