Metcalf & Eddy v. Mitchell

Background

Metcalf & Eddy were consulting engineers who advised states, cities, and local water or sewage districts and were paid fees that became partnership income. Under the War Revenue Act of 1917 they paid a federal net income tax under protest and sued to recover it, arguing some fees were exempt because they served as state officers or employees and that Congress lacked power to tax such income. The trial court found two items exempt and eighteen subject to tax; the government and taxpayers each sought review of parts of that ruling.

Reasoning

The Court addressed whether these private engineers were officers or employees of the states and whether the tax improperly taxed a state instrumentality. It explained that an "office" is a public position created by law with defined tenure, duties, and pay, and that these engineers were hired under contracts and acted as independent contractors, using professional judgment without the kind of control typical of employees. The Court also said federal tax immunity protects only agencies that directly exercise sovereign government powers, and mere contract work for a state does not make a private person an exempt government instrumentality. Because the tax was applied without discrimination and did not substantially impair the states’ functions, the tax was lawful.

Real world impact

The decision means private professionals and firms who contract with states for engineering or similar services cannot claim automatic exemption from federal income tax simply because they serve a public project. The Court affirmed the judgment taxing the eighteen items and dismissed the government’s challenge to the two exempt items that the Collector did not press.
