If your organization is tax exempt, please get in touch with us about whitelisting your account by filling out the Contact Us form. Be sure to attach the necessary tax exemption documents to the form. A representative in our customer service will whitelist your account so future purchases are tax exempt. Bookshop can also retroactively refund any taxes paid to purchases made prior to establishing a tax exempt account. Please provide the purchase order numbers, dates of purchase, total amount charged, or any other identifying information for purchases that need a retroactive refund applied.
