Hello I’m trying to create a tax code CA-E ( exempt) for Canada I create a tax group , I created the tax group, then I use the standard tax type for the creation of the tax code but impossible to use the tax code on a transaction. I only have a group tax limit list that appears on a transaction

Why can't you just use the tax group? That's what we have been doing. 1 tax code for PST and 1 tax code for GST then combine them as a tax group
