How much of the federal income tax does each income group pay?

In tax year 2023, the 1% of tax returns with the highest incomes paid 38.4% of all federal income tax, the next 9% paid 32.1%, the next 40% paid 26.2% and the bottom 50% paid 3.3%. In tax year 2023, the top 1% reported 20.6% of all income and the bottom 50% reported 12.3%. Groups are tax returns ranked by adjusted gross income, leaving out returns of people claimed as someone's dependent; in 2023 the top 1% started at $675,602 of income and the top half at $53,801. Income tax here is what returns owed after credits, never below zero; refundable credits paid out as refunds and payroll taxes for Social Security and Medicare aren't counted. IRS figures are estimates from a sample of returns and come out about two years after the tax year.
