Central MacHinery Co. v. Arizona State Tax Commission

1980-06-27

Headline: Federal Indian trading laws block Arizona from taxing a non‑Indian company’s sale of farm tractors on a reservation, preventing the state from collecting its transaction privilege tax on that sale.

Holding: The Court held that federal Indian trader statutes preempt Arizona’s transaction privilege tax, so the State may not tax this on‑reservation sale by a non‑Indian seller.

Real World Impact:

Prevents Arizona from collecting its transaction privilege tax on this reservation sale.
Means non‑Indian sellers making sales on reservations must still seek federal approval.
Signals that Congress, not states, must change law before such sales can be taxed.

Topics: Indian reservations, state taxation, federal preemption, trading with tribes

Summary

Background

A Arizona company sold 11 farm tractors in 1973 to Gila River Farms, a tribal enterprise of the Gila River Indian Tribe. The sale was solicited, contracted, paid for, and delivered on the reservation. The seller did not have a permanent reservation business and was not licensed as an Indian trader, but the Bureau of Indian Affairs approved the transaction. Arizona assessed a transaction privilege tax on the seller, who paid under protest and sued for a refund after state courts split on the issue.

Reasoning

The Court addressed whether federal Indian trader statutes and regulations bar the State from taxing on‑reservation sales. The majority said the statutes (25 U.S.C. §§ 261–264) and implementing rules show Congress has comprehensively regulated reservation trading to prevent fraud and unfair prices. Those federal rules apply to any person who trades on a reservation, including nonresident or itinerant sellers, so federal law preempts the State’s tax. The Court relied on earlier precedent and gave the trader statutes a broad sweep, reversing the Arizona Supreme Court.

Real world impact

Non‑Indian companies that sell goods on reservations and transactions governed by the Indian trader statutes cannot be taxed by Arizona on those sales. Sellers must still obtain federal approval when required and federal rules continue to govern pricing protections. The decision leaves any change allowing state taxation to Congress, since the Court applied the existing federal statutes broadly.

Dissents or concurrances

Two dissenting Justices argued the case differs from prior precedents because this was an isolated, approved sale by an unlicensed, nonresident seller and that Arizona has a legitimate interest in taxing businesses that benefit from state services.
