<P> According to the Origination Clause of the United States Constitution , all bills for raising revenue , generally tax bills , must originate in the House of Representatives , similar to the Westminster system requirement that all money bills originate in the lower house . Traditionally , though , appropriation bills also originate in the House of Representatives . House appropriations bills begin with `` H.R. '' , meaning `` House of Representatives '' . In reference to revenue bills , the Constitution also states that the `` Senate may propose or concur with Amendments as on other Bills . '' As with revenue bills , the Senate and House each drafts and considers its own appropriation bill . The Senate then `` cuts - and - pastes , '' substituting the language of its version of a particular appropriation bill for the language of the House bill , then agrees to the bill as amended . </P>
