If an item is subject to sales tax in the state to which the order is shipped, tax is generally calculated on the total selling price of each individual item. In accordance with state tax laws, the total selling price of an item will generally include item-level shipping and handling charges, item-level discounts, gift-wrap charges, and an allocation of order-level shipping and handling charges and order-level discounts.
The amount of tax charged on your order will depend upon many factors including Identity of the seller, type of item purchased, and destination of the shipment. Factors can change between the time you place an order and the time of credit card charge authorization, which could affect the calculation of sales taxes. The amount appearing on your order as Estimated Tax may differ from the sales taxes ultimately charged.
Your estimated tax will be displayed when you review your order during checkout. For additional details on California tax rates and to see what rate applies to you, please visit the California State Board of Equalization website.
