Summary of the Latest Federal Income Tax Data, 2022 Update (2024)

The Internal Revenue Service (IRS) has released data on individual income taxes for taxA tax is a mandatory payment or charge collected by local, state, and national governments from individuals or businesses to cover the costs of general government services, goods, and activities. year 2019, showing the number of taxpayers, adjusted gross incomeFor individuals, gross income is the total pre-tax earnings from wages, tips, investments, interest, and other forms of income and is also referred to as “gross pay.” For businesses, gross income is total revenue minus cost of goods sold and is also known as “gross profit” or “gross margin.”, income tax paid, and income tax shares by income percentiles.[1] The new data outlines the tax system under the second year of the Tax Cuts and Jobs Act (TCJA), the last year before the onset of the COVID-19 pandemic.

The data demonstrates the U.S. individual income taxAn individual income tax (or personal income tax) is levied on the wages, salaries, investments, or other forms of income an individual or household earns. The U.S. imposes a progressive income tax where rates increase with income. The Federal Income Tax was established in 1913 with the ratification of the 16th Amendment. Though barely 100 years old, individual income taxes are the largest source of tax revenue in the U.S. continues to be progressive, borne primarily by the highest income earners.

Key Findings

In 2019, taxpayers filed 148.3 million tax returns, reported earning nearly $11.9 trillion in adjusted gross income, and paid $1.6 trillion in individual income taxes.
The top 1 percent of taxpayers paid a 25.6 percent average individual income tax rate, which is more than seven times higher than taxpayers in the bottom 50 percent (3.5 percent).
The share of reported income earned by the top 1 percent of taxpayers fell to 20.1 percent from 20.9 percent in 2018. The top 1 percent’s share of federal individual income taxes paid fell to 38.8 percent from 40.1 percent.
The top 50 percent of all taxpayers paid 97 percent of all individual income taxes, while the bottom 50 percent paid the remaining 3 percent.
The top 1 percent paid a greater share of individual income taxes (38.8 percent) than the bottom 90 percent combined (29.2 percent).
The Tax Cuts and Jobs Act reduced average tax rates across income groups.

Reported Income and Taxes Paid Increased in Tax Year 2019

Taxpayers reported nearly $11.9 trillion in adjusted gross income (AGI) on 148.3 million tax returns in 2019. The number of returns filed rose by 3.9 million (2.7 percent) and reported AGI rose by $319 million (2.8 percent) above 2018 levels. Total income taxes paid rose by $42 billion to $1.58 trillion, a 2.7 percent increase above 2018. The average individual income tax rate was nearly unchanged: 13.29 percent in 2019, compared to 13.28 percent in 2018.

High-Income Taxpayers Paid the Highest Average Income Tax Rates

In 2019, taxpayers with higher incomes paid much higher average income tax rates than lower-income taxpayers.[2]

High-Income Taxpayers Paid the Majority of Federal Income Taxes

In 2019, the bottom 50 percent of taxpayers (taxpayers with AGI below $44,269) earned 11.5 percent of total AGI and paid 3.1 percent ($48.4 billion) of all federal individual income taxes.

The top 1 percent (taxpayers with AGI of $546,434 and above) earned 20.1 percent of total AGI in 2019 and paid 38.8 percent of all federal income taxes.

In 2019, the top 1 percent of taxpayers accounted for more income taxes paid than the bottom 90 percent combined. The top 1 percent of taxpayers paid $612 billion in income taxes while the bottom 90 percent paid $461 billion in income taxes.

The Tax Cuts and Jobs Act Reduced Average Tax Rates Across Income Groups

The 2019 filing season was the second filing season under the TCJA. The TCJA made many significant, but temporary, changes to the individual income tax code including lower tax rates, wider brackets, a larger standard deductionThe standard deduction reduces a taxpayer’s taxable income by a set amount determined by the government. It was nearly doubled for all classes of filers by the 2017 Tax Cuts and Jobs Act (TCJA) as an incentive for taxpayers not to itemize deductions when filing their federal income taxes., and an expanded child tax credit. The net effect of all the changes was to lower tax burdens, on average, for taxpayers across all income levels.

In 2019, individual taxpayers paid $1.6 trillion in individual income taxes, $23 billion less than in 2017, even as adjusted gross income was $946 billion higher. Average tax rates were lower in 2019 than in 2017 across all income groups. Average rates for the bottom 50 percent fell from 4.05 percent in 2017 to 3.54 percent in 2019 and for the top 1 percent, from 26.76 percent to 25.57 percent.

The share of income taxes paid by the bottom 50 percent of taxpayers changed little from 2017, when it was 3.11 percent, to 3.06 percent in 2019. The share of income taxes paid by the top 1 percent increased slightly from 38.47 percent in 2017 to 38.77 percent in 2019.

Appendix

For data prior to 2001, all tax returns that have a positive AGI are included, even those that do not have a positive income tax liability. For data from 2001 forward, returns with negative AGI are also included, but dependent returns are excluded.
Income tax after credits (the measure of “income taxes paid” above) does not account for the refundable portion of tax credits such as the earned income tax credit. If the refundable portion were included, the tax share of the top income groups would be higher and the average tax rateThe average tax rate is the total tax paid divided by taxable income. While marginal tax rates show the amount of tax paid on the next dollar earned, average tax rates show the overall share of income paid in taxes. of bottom income groups would be lower. The refundable portion is classified as a spending program by the OMB and therefore is not included by the IRS in these figures.
The only tax analyzed here is the federal individual income tax, which is responsible for more than 25 percent of the nation’s taxes paid (at all levels of government). Federal income taxes are much more progressive than federal payroll taxA payroll tax is a tax paid on the wages and salaries of employees to finance social insurance programs like Social Security, Medicare, and unemployment insurance. Payroll taxes are social insurance taxes that comprise 24.8 percent of combined federal, state, and local government revenue, the second largest source of that combined tax revenue.es, which are responsible for about 20 percent of all taxes paid (at all levels of government) and are more progressive than most state and local taxes.
AGI is a fairly narrow income concept and does not include income items like government transfers (except for the portion of Social Security benefits that is taxed), the value of employer-provided health insurance, underreported or unreported income (most notably that of sole proprietors), income derived from municipal bond interest, and net imputed rental income.
The unit of analysis here is the tax return. In the figures prior to 2001, some dependent returns are included. Under other units of analysis (like the U.S. Treasury Department’s Family Economic Unit), these returns would likely be paired with parents’ returns.
These figures represent the legal incidence of the income tax. Most distributional tables (such as those from the Congressional Budget Office, the Tax Policy Center, Citizens for Tax Justice, the Treasury Department, and the Joint Committee on Taxation) assume that the entire economic incidence of personal income taxes falls on the income earner.

Notes: N/A– Not applicable. [1] For Table 4.1, constant dollars were calculated using the U.S. Bureau of Labor Statistics’ consumer price index for urban consumers (CPI-U, 1990=100). For 2019 the CPI-U = 255.657. [2] Total income tax was the sum of income tax after credits (including the subtraction of excess advance premium tax credit repayment, the earned income credit, American opportunity credit, health coverage tax credit, and the regulated investment credit credit) limited to zero plus net investment income tax from Form 8960 and the tax fromForm 4970, Tax on Accumulation Distribution of Trusts. It does not include any refundable portions of these credits. [3] The average tax rate was computed by dividing total income tax (see footnote 2) by adjusted gross income. [4] The total number of returns does not include the returns filed by individuals to only receive the economic stimulus payment and who had no other reason to file.
