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]
Money bill While the United States of America is not a parliamentary democracy, the Origination Clause of the U.S. Constitution requires that all bills raising revenue originate in the House of Representatives, consistent with British constitutional practice; by convention, appropriation bills (bills that spend money) also originate in the House. Unlike in most Westminster systems, there are no limits on the Senate's ability to amend revenue bills or any requirement for the Senate to approve such bills within a certain timeframe. Both appropriations and revenue bills are often referred to as money bills to contrast them with authorization bills. The U.S. Supreme Court in United States v. Munoz-Flores (1990) held that: "A law passed in violation of the Origination Clause would thus be no more immune from judicial scrutiny because it was passed by both Houses and signed by the President than would be a law passed in violation of the First Amendment".[16]
