How Sales Tax Is Calculated
Product prices are shown excluding sales tax. Sales tax is calculated at checkout based on your shipping address, and it is not charged on shipping fees.
The exact rate depends on the state and local rates that apply to your delivery address, so the tax line only appears once you enter that address at checkout.
Where We Collect Tax
We collect sales tax in the U.S. states where we are required to do so. If your delivery address is in a state where we have no collection obligation, no tax is added to your order.
Tax on Shipping
Shipping charges are not taxed. Sales tax applies to the price of the products only.
Tax-Exempt Orders
If you are purchasing as a tax-exempt organization, contact our support team with your exemption certificate before placing the order. Certificates cannot be applied to an order that has already been completed.
Tax on Refunds
When an order is refunded, the sales tax collected on the returned items is refunded with it. Partial returns are refunded with the tax that applies to the returned items only.
Invoices
Your order confirmation email and the My Account → Orders page both show the tax charged as a separate line item.
Questions
For questions about the tax on a specific order, contact our support team and reference your order number.
