The Origination Clause, sometimes called the Revenue Clause,[1][2] is Article I, Section 7, Clause 1 of the U.S. Constitution. The clause says that all bills for raising revenue must start in the U.S. House of Representatives, but the U.S. Senate may propose or concur with amendments, as in the case of other bills.
The Origination Clause stemmed from a British parliamentary practice that all money bills must have their first reading and any other initial readings in the House of Commons before they are sent to the House of Lords. The practice was intended to ensure that the power of the purse is possessed by the legislative body most responsive to the people, but the British practice was modified in America by allowing the Senate to amend these bills.
This clause was part of the Great Compromise between small and large states. The large states were unhappy with the lopsided power of small states in the Senate and so the Origination Clause theoretically offsets the unrepresentative nature of the Senate by compensating the large states for allowing equal voting rights to senators from small states.
