The U.S. federal income tax system is progressive, meaning that as a person's taxable income increases, the tax rate applied to that income also increases.
VAT (Value-Added Tax) is generally considered regressive. It applies uniformly to goods and services, so lower-income individuals spend a larger share of their income on VAT-taxed items compared to higher-income individuals. For example, basic necessities like food and clothing, which make up a bigger portion of a low-income household’s budget, are taxed at the same rate as luxury goods. This disproportionately impacts those with less income.
