iExpense calculating tax for Canada

Wondering if there are any documents containing setup and usage of using the taxes in Internet Expenses. This is for the Canadian taxes (i.e. GST, HST, QST, etc.). Need to do the setups in EBTax for the internet expense and then how to enter expenses using these tax rates. I know the tax code needs to be populated on hte expense type in hte expense template.

Anyone using the internet expenses for Canada where it does the tax calculation? Any help is appreciated.

Thanks, Karin
