Regarding Sales Tax Exemption
If a U.S. customer is buying on behalf of an organization that is exempt from paying state and local sales taxes, FastSpring can refund the sales tax after the purchase has been completed. Alternatively, upon validating a specific customer's exempt status, FastSpring Support can create a custom order link for the customer that will prevent sales tax from being included on the initial order.
For sales tax refunds, customers can email a copy of their tax exemption certificate or other supporting paperwork issued by the state government to firstname.lastname@example.org along with their order reference / order ID, and our support team will refund the sales tax back to the original payment account.
From the time our support team receives a ticket with a tax refund request, it should take no more than 24-48 hours (and probably less) until the refund has been processed and we send a reply to the customer. After that, it can take a few business days for the funds to post back to the customer's payment account.
