Why does the constituition allow the federal government to levy taxes?

I've looked in my book and i got parts of the constituition that talks about taxes but it doesnt answer the question of WHY. I really need some help.

Please read the Preamble again. It takes money to fulfill the purposes of the Constitution.

We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.

I understand your confusion. While the Constitution does not explicitly state why the federal government is allowed to levy taxes, the Preamble provides some insight. The Preamble outlines the primary goals and purposes of the Constitution, such as forming a more perfect union, establishing justice, ensuring domestic tranquility, providing for the common defense, promoting the general welfare, and securing the blessings of liberty.

To achieve these goals, the federal government needs financial resources. Levying taxes is one way for the government to generate revenue to fund the various functions and responsibilities outlined in the Constitution. These functions include maintaining a functioning government, establishing and enforcing laws, providing for the common defense, promoting the general welfare, and more.

So, while the Constitution may not explicitly state the reason for allowing the federal government to levy taxes, it is implied that taxes are necessary to fulfill the purposes and responsibilities of the government as outlined in the Preamble.
