The following options are available for configuring Tax at the Product Level:
Tax Exempt – Check this box if you do not want to charge tax for the product.
Tax Rate – Enter the Product Level Tax Rate. For example, 8.25% is entered as 8.25
Taxable Amount (Optional) – If the “Taxable Amount” field is populated, the cart will use the “Taxable Amount” field to calculate tax instead of the "unit cost" field the cart normally uses. Tax is calculated prior to any coupon or discount.
