Article Six of the United States Constitution establishes the laws and treaties of the United States made in accordance with it as the supreme law of the land, forbids a religious test as a requirement for holding a governmental position, and holds the United States under the Constitution responsible for debts incurred by the United States under the Articles of Confederation. Text Clauses Debts The first clause of the Article provides that debts contracted prior to the adoption of the Constitution remain valid, as they were under the Articles of Confederation. Supremacy Clause two provides that the Constitution, federal laws made pursuant to it, and treaties made under its authority constitute the supreme law of the land.

The Supreme Court has also struck down attempts by states to control or direct the affairs of federal institutions. McCulloch v. Maryland (1819) was a significant case in this regard. The state of Maryland had levied a tax on banks not chartered by the state; the tax applied, state judges ruled, to the Bank of the United States chartered by Congress in 1816.

Congress may explicitly provide immunity from taxation in certain cases, for instance by immunizing a federal contractor. Federal employees, however, may not be
