Congressional Taxing Power
Art. I §8 cl. 1 / NFIB v. Sebelius
The rule
Congress may lay and collect taxes to provide for the general welfare. A tax is valid even if it has a regulatory effect, provided it (1) produces some revenue, (2) is not so punitive in amount or scienter as to be a penalty, and (3) is not otherwise unconstitutional (NFIB v. Sebelius).
In plain English
The taxing power is broader than the commerce power because Congress can 'tax' behavior it could not directly regulate — so long as the exaction looks like a tax rather than a fine. Look at revenue-raising, scienter requirements, and enforcement mechanism.
How examiners test it
Fact patterns describe a federal exaction on some activity; ask whether Congress had power. Even if commerce fails, taxing usually saves it.
