Article I, Section 7, Clause 1 directs that all bills for raising revenue must originate in the House of Representatives, though the Senate may propose or concur with amendments. The clause carries two prohibitions: the Senate may not originate any measure that includes a provision for raising revenue, and it may not propose any amendment that would raise revenue to a House-passed nonrevenue measure. However, the Senate can amend House revenue bills and substitute Senate language for House text.
