Maricopa County - MAR (Region Code)

Region Codes for Indian Reservations

Taxable activity occurring on an Indian Reservation must be reported separately. The following Tribal region codes should be used in place of county codes for all business activity occurring on an Arizona Indian Reservation. Activity will continue to be reported by TPT class.

For example, if your business has activity on the Gila River reservation in Maricopa County, and it has taxable retail transactions, that activity should be listed on the TPT-1 return in MAH 017 instead of MAR 017. All transactions not located on an Arizona Indian Reservation should continue to be filed under the specific county code
