Congress controls the federal government''s $6.1 trillion budget (2023) through its constitutional power to tax and spend. Article I, Section 8 requires all revenue bills to start in the House, where the Ways and Means Committee decides who pays and how much. The Senate can amend, but the House moves first. This power shapes American life: Congress taxes cigarettes at $1.01 per pack to discourage smoking, deducts mortgage interest to encourage homeownership, and exempts employer health insurance to subsidize coverage. The spending side works as a string-attached gift—accept highway funds but enforce a 0.08% blood alcohol limit, take education dollars but test students annually, grab pandemic relief but report how you spent it. South Dakota v. Dole (1987) set the rules: conditions must relate to the federal interest, states must understand the terms, and Congress cannot coerce compliance. In practice, states rarely refuse the money. The taxing and spending power makes Congress the nation''s accountant, banker, and behavioral engineer.
The taxing and spending power shapes American life through revenue collection and conditional grants. Congress uses tax policy to encourage (mortgage interest deduction) or discourage (cigarette excise tax) behavior. It's the federal government's most powerful domestic lever.
People often think Congress can spend money for any purpose it considers worthwhile. The spending power is actually limited: Congress can tax and spend only for the "general welfare," and must operate within constitutional boundaries on state power.
