Concurrent powers are those powers that are shared by both the national and state governments. These powers include the power to tax, establish courts, and regulate commerce. The Constitution grants certain powers to the national government, while reserving other powers to the states. However, there are some powers that are shared by both levels of government, and these are known as concurrent powers. This system of shared powers is designed to ensure that both the national and state governments have the ability to address the needs of their citizens while also maintaining a balance of power between the two levels of government.
