Trinityfarm Construction Co. v. Grosjean

Background

A private contractor had contracts with the United States to build levees in Louisiana and used large amounts of gasoline to run its machines. The company imported gasoline from other States, stored it in a central tank, and moved it to tanks along its work sites. Louisiana imposed an excise tax of five cents per gallon on gasoline sold, used, or consumed in the State; the law exempted sales made directly to the United States government. The contractor sued to stop the tax, arguing it unlawfully burdened the federal work, and a three-judge district court upheld the tax and dismissed the suit.

Reasoning

The Court asked whether the tax directly and necessarily burdens the federal government or its operations. It held that building and maintaining levees can be a federal activity but that the contractor here was an independent private contractor, not a federal instrumentality. The tax was not laid on the United States, the contracts, or the government’s receipts, and it differed from taxes that directly hit federal operations. The Court explained that taxes on property, machinery, and supplies used by a contractor are permissible because any effect on the federal government is indirect and consequential rather than immediate.

Real world impact

The decision lets Louisiana and similar States collect excise taxes on fuel used by private contractors working on federal projects. Contractors performing federal work remain responsible for state taxes on fuel, equipment, and supplies, while direct sales to the United States remain exempt under the State statute. This ruling affirms that contractor use of materials is generally taxable so long as the tax does not directly target the federal government.

Dissents or concurrances

Justice Cardozo concurred in the result, agreeing with the judgment to affirm.
