The department shall refund 70 percent of the taxes collected under s. 139.31(1) in respect to sales on reservations or trust lands of an Indian tribe to the tribal council of the tribe having jurisdiction over the reservation or trust land on which the sale is made if all the following conditions are fulfilled:
Wis. Stat. § 139.323
The phrase "was designated a reservation or trust land" in sub. (3) is necessarily read as referring to the applicable formal process that must occur in order for land to be a reservation or trust land. Because the proper authorities had not completed the necessary steps for the property in question to be designated a reservation or trust land on or before January 1, 1983, and because that is required in order to qualify for the tax refund, a claim for refund was properly denied.
