A case brief of McCulloch v. Maryland comes down to this: in 1819, a unanimous Supreme Court held that Congress had the constitutional authority to charter the Second Bank of the United States, and that Maryland could not tax that bank. Chief Justice John Marshall’s opinion established the doctrine of implied powers under the Necessary and Proper Clause and the rule that states cannot tax federal instrumentalities.
Case Citation and Basics
McCulloch v. Maryland, 17 U.S. (4 Wheat.) 316 (1819). Argued over nine days in February and March 1819. Decided unanimously. Opinion by Chief Justice John Marshall. Daniel Webster and William Pinkney argued for McCulloch and the bank; Luther Martin, Maryland’s attorney general, argued for the state.1Justia U.S. Supreme Court Center. McCulloch v. Maryland
Facts
Congress chartered the Second Bank of the United States in 1816 to stabilize the post-war economy and manage federal finances.2Federal Reserve History. The Second Bank of the United States The bank opened branches across the country, including one in Baltimore. Many states saw the bank as federal intrusion on state banking.
In 1818, the Maryland legislature passed a law requiring any bank operating in the state without a Maryland charter to print its notes on special stamped paper purchased from the state, or pay an annual tax of $15,000. The Baltimore branch of the Second Bank was the only institution the law reached.1Justia U.S. Supreme Court Center. McCulloch v. Maryland
James McCulloch, the cashier of the Baltimore branch, issued banknotes without the required stamps and refused to pay the tax. Maryland sued. The state trial court ruled for Maryland, and the Maryland Court of Appeals affirmed, holding not only that the tax was valid but that the Second Bank itself was unconstitutional because the Constitution nowhere expressly authorizes Congress to charter a bank.3Cornell Law Institute. McCulloch v. State of Maryland et al. McCulloch appealed to the Supreme Court.
Issues
Two questions were before the Court:
- Does Congress have the constitutional authority to charter a national bank, given that no provision of the Constitution expressly grants that power?
- If so, may a state tax that federally chartered institution?
Holding
Yes to the first question; no to the second. Congress had the power to incorporate the Second Bank under the Necessary and Proper Clause, and Maryland’s tax on the bank was unconstitutional. The Maryland Court of Appeals was reversed.4National Archives. McCulloch v. Maryland (1819)
Reasoning: Implied Powers
Marshall’s opinion grounded congressional authority to charter the bank in the Necessary and Proper Clause, which empowers Congress to “make all Laws which shall be necessary and proper for carrying into Execution” its enumerated powers.5Constitution Annotated. Article 1 Section 8 Clause 18 Maryland had argued that “necessary” meant absolutely indispensable, so anything Congress could theoretically manage without was off-limits.
Marshall rejected that reading. He wrote that the Constitution is “intended to endure for ages to come” and must be adaptable to new circumstances. In context, “necessary” means useful or conducive to a legitimate end, not strictly essential. Congress has enumerated powers to tax, borrow money, regulate commerce, and support armies and navies. A national bank is a rational means of carrying out those powers.
From this, Marshall articulated the test that still frames the analysis: “Let the end be legitimate, let it be within the scope of the constitution, and all means which are appropriate, which are plainly adapted to that end, which are not prohibited, but consist with the letter and spirit of the constitution, are constitutional.”1Justia U.S. Supreme Court Center. McCulloch v. Maryland This is the source of the implied powers doctrine: Congress is not confined to acts the Constitution specifically lists, and may adopt any reasonable means to execute the powers it does have.
Marshall also addressed Maryland’s structural argument that the Constitution was a compact among sovereign states. He responded that the Constitution was ratified by conventions of delegates chosen by the people, not by state legislatures. The federal government “proceeds directly from the people” and is “ordained and established in the name of the people.”1Justia U.S. Supreme Court Center. McCulloch v. Maryland It therefore does not derive its authority from, and is not subordinate to, the individual states.
Reasoning: The State Cannot Tax the Federal Government
On the second issue, Marshall turned to the Supremacy Clause of Article VI, which makes federal law “the supreme Law of the Land” and binds state judges to it despite any contrary state law.6Library of Congress. U.S. Constitution – Article VI Because Congress had validly created the bank, a state law imposing a burden on that bank conflicted with federal authority.
Marshall put the underlying principle in a single line that has been quoted ever since: “the power to tax involves the power to destroy.”4National Archives. McCulloch v. Maryland (1819) If Maryland could impose a $15,000 tax, it could raise the tax high enough to close the bank. And if Maryland could do it, every state could. A federal institution serving the entire nation cannot be left at the mercy of one state’s voters, who impose costs on citizens of every other state without representing them.
The Court accordingly held that states may not directly tax federal instrumentalities. This is the origin of the intergovernmental tax immunity doctrine, which courts have since refined to permit states to tax private parties dealing with the federal government so long as the tax does not discriminate against the federal government or its contractors.7Constitution Annotated.

Significance
McCulloch is one of the most cited decisions in American constitutional law because it settled two structural questions that reach far beyond banking. The implied powers doctrine gives Congress room to legislate on subjects the framers never anticipated, and much of modern federal regulatory authority rests on the reading of the Necessary and Proper Clause that Marshall set out.8Constitution Annotated. Necessary and Proper Clause Early Doctrine and McCulloch v. Maryland The tax immunity holding continues to shape the fiscal relationship between the federal government and the states, from the treatment of federal bonds under state tax law to the status of federal facilities within state borders.7Constitution Annotated.
