Sonzinsky v. United States

Background

A man convicted in federal court for dealing in firearms without paying the required federal license tax challenged the law as unconstitutional. The appeals court affirmed his conviction on the count charging nonpayment under §2, and the Supreme Court agreed to decide only whether §2’s $200 annual dealer tax is a valid exercise of Congress’s taxing power. The National Firearms Act also requires dealers to register, taxes importers and manufacturers $500, levies a $200 transfer tax, and defines covered “firearms” (for example, short-barreled rifles or other concealable weapons and machine guns).

Reasoning

The central question was whether the $200 levy is a true tax or a penalty meant to suppress certain firearms—an area the petitioner said states, not the national government, should control. The Court found §2 to be on its face a tax: it produces revenue, contains only registration rules that support revenue collection, and is separable from other provisions. The opinion stressed that taxes may have regulatory effects but remain taxes, and courts will not probe Congress’s hidden motives. Because the levy operates as a tax and produces some revenue, the Court sustained the conviction for nonpayment and did not rule on the separate transfer tax and identification regulations.

Real world impact

As a result, dealers nationwide must register and pay the federal dealer license tax or risk criminal conviction for nonpayment. The ruling treats a burdensome or deterrent tax as constitutionally permissible, and the Court left open the separate question of the transfer tax and other rules. The opinion notes that 27 dealers paid the tax in 1934 and 22 in 1935, showing some revenue collection.
