We are pulling out sales tax for posting to accounting systems. But we need more information to make it unique and we just cannot figure out how to get it. GST or PST is not enough for Canada without the province and for the USA the title in tax_lines are also not unique and don't tell us which state. How do we get that info linked to the amounts in tax_lines on the order?
I know TaxJar and Avalara get this info so why can we not figure this out what are we missing?
