What branch of government has the power to tax?

Amongst the three branches of government, only one branch can tax the people of the United States. Granted by Article I, Section 8 of the U.S. Constitution, the legislative branch of the government has the power to create, enforce, and collect taxes for the government. They have been the sole administrators of tax since the very beginning of the formation of the United States. Congress is in charge of taxing in order, "to provide for the common defense and general welfare," of the nation which allows for us to maintain a strong infrastructure within our society.
