What principle does progressive income taxation follow in the United States?

Progressive income taxation in the United States operates on the principle that individuals with higher incomes should pay a higher percentage of their income in taxes compared to those with lower incomes. This system is structured into income brackets, with each bracket corresponding to a different tax rate. As a taxpayer’s income increases and crosses into higher brackets, the additional income is taxed at a progressively higher rate.

This method of taxation aims to alleviate the financial burden on those with lesser earnings while ensuring that those who have greater financial resources contribute a larger share toward funding public services and programs. The progressive nature of the tax system reflects a commitment to equitable financial contributions based on one’s ability to pay, which promotes social equity within the economy.

The other options do not align with the principles of progressive taxation; an equal tax rate for all income levels suggests a flat tax system, which does not consider income disparities. A flat tax rate applied uniformly to all earnings overlooks the principle of fairness and ability to pay, while higher corporate tax rates specifically target business income rather than individual income, diverging from personal income taxation principles entirely.
