Hi, Gail,

Your question is fairly general. You can set up Tax Statuses in the OE Profile (tax status are entered into the item and customer records) and Tax Groups in OE Edit | Tax Groups which use these statuses.

In IC, within the items on the Units tab, you specify the Tax Status the item will use.

When the order is created in OE, the Tax Status and Group are entered in the header tab for/from the customer. The items Tax Status is entered for/from the item on the detail tab.

OE will use the lowest of the item or customer tax.

There is online Help documentation for each of these features also.
