1. That part of the National Firearms Act which provides that
every dealer in firearms shall register and shall pay an annual tax
of $200 or be subject to fine and imprisonment is a valid exercise
of the taxing power of Congress. Pp.

et seq.
The term "firearm" is defined by § 1 of the Act as meaning
a shotgun or rifle having a barrel less than eighteen inches in
length, or any other weapon, except a pistol or revolver, from
which a shot is discharged by an explosive, if capable of being
concealed on the person, or a machine gun, and includes a muffler
or silencer for any firearm.

MR. JUSTICE STONE delivered the opinion of the Court.
The question for decision is whether § 2 of the National
Firearms Act of June 26, 1934, c. 757, 48 Stat. 1236, 26 U.S.C.
§§ 1132-1132q, which imposes a $200 annual license tax on
dealers in firearms, is a constitutional exercise of the
legislative power of Congress.
Petitioner was convicted by the District Court for Eastern
Illinois on two counts of an indictment, the first charging him
with violation of § 2 by dealing in firearms without payment
of the tax. On appeal, the Circuit Court of Appeals set aside the
conviction on the second count and affirmed on the first. 86 F.2d
486. On petition of the accused we granted certiorari, limited to
the question of the constitutional validity of the statute in its
application under the first count in the indictment.
Section 2 of the National Firearms Act requires every dealer in
firearms to register with the Collector of Internal Revenue in the
district where he carries on business, and to pay a special excise
tax of $200 a year. Importers or manufacturers are taxed $500 a
year. Section 3 imposes a tax of $200 on each transfer of a
firearm, payable by the transferor, and § 4 prescribes
regulations for the identification of purchasers. The term
"firearm" is defined by § 1 as meaning a shotgun or a rifle
having a barrel less than eighteen inches in length, or any other
weapon, except
Page 300 U. S. 512
a pistol or revolver, from which a shot is discharged by an
explosive, if capable of being concealed on the person, or a
machine gun, and includes a muffler or silencer for any firearm. As
the conviction for nonpayment of the tax exacted by § 2 has
alone been sustained, it is unnecessary to inquire whether the
different tax levied by § 3 and the regulations pertaining to
it are valid. Section 16 declares that the provisions of the act
are separable. Each tax is on a different activity, and is
collectible independently of the other. Full effect may be given to
the license tax standing alone, even though all other provisions
are invalid.

S. 319;

In the exercise of its constitutional power to lay taxes,
Congress may select the subjects of taxation, choosing some and
omitting others.
See Flint v. Stone Tracy Co.,
220 U. S. 107,
220 U. S. 158;

power extends to the imposition of exercise taxes upon the doing of
business.

Cases, 5 Wall. 462;
Spreckles Sugar Refining
Co. v. McClain, 192 U. S. 397,
192 U. S. 412;
United States v. Doremus, 249 U. S.
86,
249 U. S. 94.
Petitioner does not deny that Congress may tax his business as a
dealer in firearms. He insists that the present levy is not a true
tax, but a penalty imposed for the purpose of suppressing traffic
in a certain noxious type of firearms, the local regulation of
which is reserved to the states because not granted to the national
government. To establish its penal and prohibitive character, he
relies on the amounts of the tax imposed by § 2 on dealers,
manufacturers, and importers, and of the tax imposed by § 3 on
each transfer of a "firearm," payable by the transferor. The
cumulative effect on the distribution of a limited class of
firearms of relatively small value by the successive imposition of
different taxes, one on the
Page 300 U. S. 513
business of the importer or manufacturer, another on that of the
dealer, and a third on the transfer to a buyer, is said to be
prohibitive in effect, and to disclose unmistakably the legislative
purpose to regulate, rather than to tax.
The case is not one where the statute contains regulatory
provisions related to a purported tax in such a way as has enabled
this Court to say in other cases that the latter is a penalty
resorted to as a means of enforcing the regulations.
See Child
Labor Tax Cases, 259 U. S. 20,
259 U. S. 35;
Hill v. Wallace, 259 U. S. 44;
Carter v. Carter Coal Co., 298 U.
S. 238. Nor is the subject of the tax described or
treated as criminal by the taxing statute.
Compare United
States v. Constantine, 296 U. S. 287.
Here, § 2 contains no regulation other than the mere
registration provisions, which are obviously supportable as in aid
of a revenue purpose. On its face, it is only a taxing measure, and
we are asked to say that the tax, by virtue of its deterrent effect
on the activities taxed, operates as a regulation which is beyond
the congressional power.
Every tax is in some measure regulatory. To some extent, it
interposes an economic impediment to the activity taxed, as
compared with others not taxed. But a tax is not any the less a tax
because it has a regulatory effect,

supra, 249 U. S. 93-94;
Nigro v. United States, 276 U. S. 332,
276 U. S.
353-354;
License Tax cases, supra; see Child Labor
Tax cases, supra, 259 U. S. 38,
and it has long been established that an Act of Congress which, on
its face, purports to be an exercise of the taxing power is not any
the less so because the tax is burdensome or tends to restrict or
suppress the thing taxed.

They will not undertake, by collateral inquiry as to the measure of
the regulatory effect of a tax, to ascribe to Congress an attempt,
under the guise of taxation, to exercise another power denied by
the Federal Constitution.

Magnano Co. v. Hamilton, supra, 292 U. S.
45.
Here, the annual tax of $200 is productive of some revenue.
* We are not free
to speculate as to the motives which moved Congress to impose it,
or as to the extent to which it may operate to restrict the
activities taxed. As it is not attended by an offensive regulation,
and since it operates as a tax, it is within the national taxing
power.
