the power of the purse or the power to raise taxes and allocate revenues belongs to
Taxing and Spending Clause The Taxing and Spending Clause[1] (which contains provisions known as the General Welfare Clause)[2] and the Uniformity Clause,[3] Article I, Section 8, Clause 1 of the United States Constitution, grants the federal government of the United States its power of taxation. While authorizing Congress to levy taxes, this clause permits the levying of taxes for two purposes only: to pay the debts of the United States, and to provide for the common defense and general welfare of the United States. Taken together, these purposes have traditionally been held to imply and to constitute the federal government's taxing and spending power.[4]
Appropriation bill 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.[8][9] 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.
