McCulloch v. Maryland in AP US Government

The tax question is only half of McCulloch

A lot of people remember McCulloch as "the case where a state couldn't tax the bank" and stop there. That's the second half of the decision. The first half, and the part that does more work in AP Gov, is whether Congress had the power to create the bank at all.

Congress chartered the Second Bank of the United States in 1816. Maryland then passed a tax on banks operating in the state without a state charter, which hit the bank's Baltimore branch. James McCulloch, the branch's cashier, refused to pay, and Maryland took him to court.

Maryland argued that the Constitution never mentions a bank, so Congress had no authority to create one, and that a state could tax anything operating inside its borders. That gave the Court two questions. Marshall, writing for a unanimous Court, said yes, Congress can charter the bank, and no, Maryland can't tax it.

How Marshall got a bank out of "necessary and proper"

Marshall tied the bank to powers Article I does list: taxing, borrowing money, regulating commerce, and raising armies. Article I, Section 8 ends by letting Congress make all laws "necessary and proper" for carrying out those powers.

Maryland read "necessary" as absolutely indispensable. Marshall read it as useful or appropriate: "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."

He also answered Maryland's reserved-powers argument. The Tenth Amendment doesn't say powers "expressly" delegated, as the Articles of Confederation had, so Congress isn't limited to the exact words of its list. This is where implied powers become an accepted category of national power, the one Topic 1.7 lists next to enumerated powers.

Why "the power to tax involves the power to destroy"

On the tax, Marshall reasoned that if one state could tax a federal institution, it could tax it out of existence. That would let a single state undo a law the whole nation made through Congress. Because the Supremacy Clause makes the Constitution and federal laws made under it "the supreme Law of the Land," a state tax aimed at a valid federal operation can't stand.

The holding had limits. Marshall said it didn't stop Maryland from taxing the bank's real property the way it taxed other real property. Taxing is a concurrent power, and McCulloch marks where a state's share of that power stops: at the point where it burdens the national government's own operations. That's the principle of national supremacy.

McCulloch's job in Unit 1's argument over federal power

In Unit 1, Foundations of American Democracy, Topic 1.8 (Constitutional Interpretations of Federalism) is where McCulloch does its main work. That topic asks how Supreme Court readings of the Necessary and Proper, Commerce, and Supremacy Clauses have shifted the balance between national and state power over time. McCulloch is the early, big push toward national power. It also supports Topic 1.7 (implied powers as exclusive national power) and Topic 1.9 (concurrent powers like taxing shape what each level can do).

The case connects to the Anti-Federalist side too. Brutus 1 warned that the Necessary and Proper and Supremacy Clauses would let the national government swallow the states. On the Argument Essay (Question 4), you must use at least one specified foundational document and may also use relevant course knowledge. McCulloch fits as that course knowledge for a claim about federal power growing beyond the list in Article I, either to back Brutus's warning or to back the Federalist case for a strong central government.

Pairing McCulloch with Lopez and other limits on federal power

The tempting wrong answer on a McCulloch question is judicial review, because Marbury v. Madison is also a Marshall opinion. When a question describes the ruling and asks what principle it set up, the right answer points to implied powers or national supremacy. The other usual wrong choices are dual federalism and states' rights.

The contrast case is United States v. Lopez (1995), another required case. Congress had used the Commerce Clause to pass the Gun-Free School Zones Act of 1990, and the Court struck it down because carrying a gun near a school isn't economic activity that substantially affects interstate commerce. McCulloch expanded federal power through the Necessary and Proper and Supremacy Clauses. Lopez limited it through a narrower reading of the Commerce Clause. United States v. Morrison (2000), which struck down part of the Violence Against Women Act of 1994, follows the Lopez line.

On the SCOTUS Comparison (Question 3), you get a summary of a non-required case and compare it to a required one. If the new case involves Congress reaching past its listed powers (such as United States v. Comstock (2010), which upheld a federal civil-commitment law under the Necessary and Proper Clause), McCulloch is your match. A strong answer does three things:

• names the clause the two cases share
• explains how the facts in each led to its holding
• connects both holdings to the balance between national and state power

Watch out for three mistakes: calling McCulloch a Commerce Clause case, naming only one of its two clauses when the question wants a specific one, and saying McCulloch made federal power unlimited. Marshall required the end to be legitimate and within the Constitution's scope, and Lopez shows the Court enforcing limits.
