in which house of congress must revenue bills originate and why
Origination Clause The Origination Clause, sometimes called the Revenue Clause, is part of Article I of the United States Constitution. This clause says that all bills for raising revenue must start in the House of Representatives, but the Senate may propose or concur with amendments as in the case of other bills.
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]
