A passport is federal. A driver’s license is state. A zoning permit is local — knowing which matters more than knowing the theory.
Federalism divides governing authority between the national government and the states. The Constitution grants the federal government certain powers, reserves many powers to the states, and leaves real areas of genuine overlap in between.
Before contacting government, ask which level owns the problem.
Guide to Government
Who Actually Handles What
Federal responsibilities
National defense, foreign affairs, immigration, federal taxes, interstate commerce, federal courts, and federal benefits.
State responsibilities
Elections administration, public schools, driver licensing, state courts, family law, professional licensing, and policing.
When the Two Levels Genuinely Overlap
Many programs are cooperative by design
When federal and state law genuinely conflict, the Constitution’s Supremacy Clause can make valid federal law controlling. But a large share of real government programs aren’t a conflict at all — they’re cooperative, with federal standards and state administration working together on the same issue, which is exactly why a single problem (health, education, or benefits, for example) can genuinely involve more than one level of government at once.

The Supremacy Clause doesn’t erase state authority across the board
A common misconception is that federal law simply overrides state law whenever the two touch the same general subject. The Supremacy Clause only makes valid federal law controlling in a genuine conflict — and many areas states handle (like most family law, most licensing, most local policing) have no comparable federal law at all, meaning there’s no conflict to resolve in the first place. Federal supremacy is a real, but narrower, principle than “federal always wins.”
