Ship to location tax in R12

Hi, 

In Oracle apps R12, we require to define tax for ship-to location.

We have many supplies where few of them have same type of ship to location for PO shipment. We had define the location with tax in11i but not have idea how can we define a new tax for new define location for PO shipments.

Exp: we define a new location NJ and want to define a tax on NJ for PO shipment.

Can you please share the steps ASAP. We are facing some urgent issue need help to resolve asap.

Thanks in advance.
