General Sales Tax Exemption Certificate

Indiana registered retail merchants and businesses located outside Indiana may use this certificate. The claimed exemption must be allowed by Indiana code. Exemption statutes of other states are not valid for purchases from Indiana vendors. This exemption certificate can not be issued for the purchase of Utilities, Vehicles, Watercraft, or Aircraft. Purchaser must be registered with the Department of Revenue or the appropriate taxing authority of the purchaser’s state of residence.

Sales tax must be charged unless all information in each section is fully completed by the purchaser. Purchasers not able to provide all required information must pay the tax and may file a claim for refund (Form GA-110L) directly with the Department of Revenue. A valid certificate also serves as an exemption certificate for (1) county innkeeper’s tax and (2) local food and beverage tax.
