What Is Eligible for Sales Tax in Idaho?

Idaho charges sales tax on physical goods and some services with only a handful of exemptions based on certain circumstances.

Tax Exemptions exist for manufacturing equipment and machinery, medical devices, and prescription drugs as well. Before assuming an exception to any of the sales tax applied in Idaho, be sure to review the documentation to receive an exemption certificate on the State Tax Commission’s website.

Registration

The State of Idaho requires that all businesses that must collect sales tax register with the state. You can do so through the State Tax Commission’s website using the IBR-1 form. This form is a combined form for the Tax Commission, Industrial Commission, and Idaho Department of Labor and applies to both in-state and out-of-state sellers. If you are out of state and the remainder of the form’s purposes do not apply to you, there are detailed instructions online for how to complete it.

After completing the IBR form, you will receive your account number and permit for payment within 10 days. This will provide you with the Idaho Seller’s Permit needed to do business in the state.
