Customers placing orders in TXShop are prompted during checkout to state whether or not they are tax exempt. If a customer indicates that they are not tax exempt, then sales tax will be charged.

Customers who are paying with departmental funds (i.e. state funds) are not subject to sales tax. Tax-exempt customers are required to complete a tax-exemption questionnaire during the checkout process, and may be required to submit a paper copy exemption certificate if one is not already on file at the University.
