    What if my organization is tax exempt?

    Sales tax is charged on all Parts online orders. If you proceed with a guest checkout, you will be charged tax. If you believe your organization should be exempt from sales tax, you must create an account . Proceed with placing your order and then email with a pdf of your tax exempt certificate with reference to the order number submitted. Once the certificate is approved, a credit will be issued via the payment method used on the original order within a few days. The entire process could take up to five days. Your organization’s exemption certification will be kept on file and future orders will be tax exempt through the validity date on your exemption certificate.
