The Product Tax Category determines the amount of Sales Tax to be applied when a Charge for the Product/Service is added to an Order/Bill.
Product Tax Categories are configured via the 'Product Setup' screen → 'Tax Setup' tab → 'Product Tax Category Setup' subtab.
For each Tax Jurisdiction, each Tax Category is assigned the Tax Rate for a valid period.
Tax Jurisdictions are combined into Tax Regions, which usually represent a geographic area.
A Tax Region will contain the Point of Sale, or a Tax Nexus (in the case of Field Services), or the Customer Location to which a Taxable Product was delivered.
The Tax Region is assigned to the Hospital Unit via the 'Hospital Setup' screen → 'Unit Setup' tab → 'Unit Details' subtab; OR,
Selected from the 'Tax Region' drop-down list at the top of the 'Order Management' screen → 'Order Details' section.
