The US federal and state governments have certain powers that overlap, but they also have distinct areas of authority. Both levels of government have the power to:

1. Create and enforce laws within their respective jurisdictions.
2. Levy and collect taxes to fund government operations and services.
3. Establish and maintain courts and a justice system.
4. Regulate various aspects of public policy, such as education, transportation, and public safety.

However, it's important to note that the US Constitution delineates specific powers for the federal government, while reserving other powers for the states through the Tenth Amendment. The federal government handles matters like foreign affairs, national defense, currency, and interstate commerce, while states manage areas such as education, local law enforcement, and intrastate commerce. This division of powers defines the differences in their authority and responsibilities.
