Which part of the legislative branch is responsible for introducing revenue bills?

The House of Representatives is specifically responsible for introducing revenue bills due to the provisions laid out in the U.S. Constitution. This responsibility is rooted in Article I, Section 7, which states that all bills for raising revenue must originate in the House of Representatives. This requirement emphasizes the principle that those who are closest to the voters should have the primary say in financial matters, reflecting a democratic approach to taxation and government spending.

The structure of the legislative branch is designed to ensure that the House, composed of representatives directly elected by the people, plays a crucial role in fiscal decisions. In contrast, the Senate does not have this exclusive responsibility for revenue bills, although it can amend and debate these bills after they have been introduced in the House. Joint Committees and the Judiciary do not have any authoritative role in introducing revenue bills, as their functions serve different purposes within the government.
