The power to collect taxes in the U.S. is an example of concurrent powers.
Explanation: Concurrent powers are those powers that are shared by both the federal government and the state governments. In the context of the U.S., the Constitution gives both levels of government the authority to impose taxes. This means that both states and the federal government can collect taxes to fund their respective operations, programs, and services. For instance, while the federal government collects income taxes, state governments impose sales taxes. This dual ability to tax is fundamental to the functioning of government at all levels in the United States.
