Unable to automatically calculate taxes on an AR Invoice

Content

We are trying to calculate taxes automatically on invoices in Receivables for Canada with no luck. I believe everything is configured correctly because the calculation of taxes in AP for invoices is working perfectly.

Can AR calculate taxes with no tax determinants filled in on the line level? When we select a tax classification code for the line, it will sometimes calculate correctly. For example, If we have a bill-to/ship-to in Ontario and select the ON HST tax classification, taxes will calculate correctly. However this doesn't work for non-HST provinces. Like for British Columbia, if we choose the BC GST it will calculate the GST, and if we choose the BC PST it will calculate that, but it will not calculate both.
