Regions that assess tax include countries, states, provinces, counties, districts, and cities. In GTM, a region that assesses tax, or is subject to the same set of tax types, is a tax zone. All customer, supplier, and company address records belong to a tax zone, and each transaction has at least one set of ship-from and ship-to tax zones.

Tax zones correspond to nexuses in AvaTax. See Nexuses.

Use Tax Zone Maintenance (29.2.1) to create a unique code that identifies the Canadian tax zone and another unique code for the US tax zone.
