Interstate Oil Pipe Line Co. v. Stone

1949-06-27

Headline: Upheld Mississippi’s two-percent tax on gross receipts from operating in‑state oil pipelines, allowing the State to tax loading receipts even when the oil is billed for shipment out of state.

Holding: The Court affirmed that Mississippi may impose a two percent privilege tax measured by gross receipts for operating oil pipelines within the state, even when that oil is billed for shipment to out‑of‑state destinations.

Real World Impact:

Allows states to tax pipeline companies on receipts from in‑state loading operations.
Makes companies transporting oil to in‑state rail loading points liable for state privilege taxes.
Permits states to tax activities carried on wholly within their borders without further apportionment.

Summary

Background

A Delaware pipeline company that gathers oil from lease tanks in Mississippi and moves it to railroad loading racks challenged a Mississippi tax. The state assessed $20,296.36 for 1944–1946 under statutes that levy annual privilege taxes and a two percent tax on gross income for operating pipelines in the state. The oil is shipped by rail as the owner’s agent to out‑of‑state destinations; there are no refineries in Mississippi and loading delays rarely exceed a week.

Reasoning

The Court affirmed the judgment that sustained the State Tax Commission’s assessment. The majority explained that the Court looks to how a tax actually operates, not just its label. Because the taxed activities were carried on entirely in Mississippi, the tax did not violate due process or discriminate against interstate commerce. The opinion relied on earlier decisions that allowed apportioned gross‑receipts or privilege taxes for activities within a State and concluded apportionment was unnecessary here because no other State could be taxed for these in‑state operations.

Real world impact

Pipeline companies that move oil from field tanks to in‑state rail loading points can be required to pay state privilege taxes measured by those in‑state receipts, even when the oil is destined out of state. States may lawfully collect nondiscriminatory taxes tied to business done wholly within their borders under the reasoning in this opinion.

Dissents or concurrances

A dissent argued the in‑state movement was part of interstate commerce once shippers gave out‑of‑state shipping orders, and that taxing the privilege of doing interstate business is unconstitutional; a separate concurrence rested on a view that the tax applied only to intrastate activity.
