Do I have to get an exemption certificate on all my customers making an exempt purchase?


The documentation required depends on the sales transaction and the purchaser. All transactions exempt from sales tax must be properly documented. Louisiana does not accept other state exemptions or the multi-state exemption certificate. Exemptions are not transferable which means the certificate holder must be the purchaser to qualify. Sales transactions in bona fide interstate commerce would be documented with the purchase, invoice and bill of lading. A drop shipment letter is needed to document a third party sales transaction in bona fide interstate commerce. Call (855) 307-3893 and follow the prompts or email [email protected] for additional information if needed.
