How State and Federal Governments Divide Power

The United States doesn't have just one level of government making every decision.

Instead, power is divided between the federal government and state governments. This system, known as federalism, allows the national government to handle certain issues affecting the country as a whole while states retain authority over many matters closer to home.

Understanding that division can make it easier to see why laws and rules sometimes differ depending on where you live.

The Constitution Gives the Federal Government Specific Powers

The federal government doesn't have unlimited authority.

The Constitution grants Congress specific powers. Article I, Section 8 includes powers such as collecting taxes, regulating interstate and foreign commerce, establishing rules for naturalization, coining money, and declaring war.

These are often called enumerated powers because they are specifically listed in the Constitution.

The federal government also has authority necessary to carry out its constitutional responsibilities. The Necessary and Proper Clause allows Congress to make laws needed to execute the powers granted to the federal government.

States Keep Many Other Powers

The Constitution also recognizes an important role for the states.

The Tenth Amendment says that powers not delegated to the United States by the Constitution, and not prohibited to the states, are reserved to the states or the people.

As a result, states exercise broad authority in many areas that affect everyday life.

State and local governments play major roles in areas such as education, local government, property matters, professional licensing, and many public safety rules. Each state also has its own constitution and governmental structure.

This helps explain why laws can differ significantly from one state to another.

Some Powers Are Shared

The division isn't always as simple as federal versus state.

Both levels of government exercise certain powers. Federal and state governments can collect taxes, establish courts, make and enforce laws within their respective authority, and spend money for public purposes.

This overlap means you regularly interact with more than one level of government.

You might pay both federal and state income taxes, for example. A business may also need to follow federal requirements while complying with separate state licensing or employment rules.

Federal Law Can Take Priority

What happens when state and federal laws conflict?

Article VI contains the Supremacy Clause, which establishes the Constitution, valid federal laws, and treaties as the supreme law of the land. When federal law is constitutionally valid and conflicts with state law, federal law can take precedence.

However, determining whether federal law actually displaces a state law can involve complicated legal questions.

Not every difference between federal and state law automatically creates a constitutional conflict.

Federalism Creates Different Centers of Government

Dividing power creates a system in which decisions can be made at different levels.

A national issue may require federal action, while another matter may primarily fall within state authority. In other situations, both governments may have responsibilities.

That structure can sometimes seem complicated, especially when laws overlap.

But the division serves an important constitutional purpose. Rather than concentrating governmental authority in one place, the Constitution distributes power between the national government and the states.

Knowing which level of government has authority over an issue can help you better understand the laws that affect your everyday life and the constitutional system behind them.
