Which chamber of Congress is responsible for initiating revenue bills?

The House of Representatives is designated as the chamber of Congress responsible for initiating revenue bills. This is based on the U.S. Constitution, specifically Article I, Section 7, which stipulates that all bills for raising revenue must originate in the House.

This provision reflects the framers' intention to ensure that the body more directly accountable to the electorate—serving shorter terms and representing smaller districts—would have the primary role in proposing legislation that affects the taxation and financial obligations of citizens.

In contrast, while the Senate plays a significant role in the legislative process, it typically reviews and modifies the revenue bills initiated by the House, but does not originate them. Other choices, such as the National Assembly and the Supreme Court, are not relevant in this context, as they do not pertain to the U.S. legislative structure. The National Assembly is a term used in other countries and does not exist within the U.S. system, and the Supreme Court’s role is judicial rather than legislative.
