Sales tax was added to my order; isn’t this program tax-exempt?

All orders under the UABC should have the sales tax exemption available right away. Please review your orders carefully to ensure the tax is correct, depending on the goods being purchased.

Even though you are registered in the Amazon Tax Exemption Program, in some cases, sales tax may still be charged on items you order from any seller who lists products for sale via the website. If you make a business-related purchase and sales tax is applied, departments should request a refund directly from Amazon.

To Request Refund on Taxes Charged (by third parties):


  1. Go to “your orders” on
  2. Find the item that was charged tax and click the “contact the seller” button (If this button is not there, call 888-281-3847)
  3. Enter subject as “Tax Exemption Refund Request”
  4. Include the order number and amount charged.


The seller is required to respond within 72 hours. They may ask for some additional information, but if not they should just issue the refund.


If you have any issues contacting the seller, or other questions, you can also contact our tax team (number below).


If the item was fulfilled by Amazon, simply call the tax support team:
