Atlantic Coast Line Railroad Co. v. Daughton

Background

Four railroad companies that own and operate lines in North Carolina challenged the State’s 1921 income tax law. The statute set a three percent corporate income tax and treated public service corporations, including railroads, under a special accounting rule based on Interstate Commerce Commission records. The companies sued to stop collection, claiming the law improperly taxed gross income, denied legitimate deductions like interest and rents, and violated the U.S. Constitution and the State constitution. The District Court dismissed the suits and the cases were appealed to the Supreme Court.

Reasoning

The central question was whether North Carolina could tax the net income of the railroad property operated inside the State while disallowing certain capital charges as deductions. The Court held that the State law taxes the net income of the property used in the State, not the entire company, and that many of the denied items are capital charges rather than operating expenses. The Court found no unconstitutional burden on interstate commerce, no unlawful discrimination, and no conflict with the Interstate Commerce Commission’s accounting rules. Because the State acted on the property as the taxable entity, the different deductions for public service corporations were reasonable, and the law was upheld.

Real world impact

Railroads and similar public service companies will be taxed on the net operating income attributable to property used in the State and may not deduct certain capital costs like funded interest and leased‑line rents. The decision affirms the State’s method of calculation and allows collection under the statute as construed by the Court.
