The top earners and corporations carry the largest share of federal income tax

The wealthiest households and largest corporations pay the majority of federal income taxes collected in the United States. The top 1 percent of earners—those making roughly $600,000 or more annually, though this threshold shifts year to year—pay around 40 percent of all federal income tax. The top 10 percent pay roughly 70 percent. This means the bottom 50 percent of earners pay a much smaller share, often cited as around 2 to 3 percent of total federal income tax.

These figures describe federal income tax only. When you add payroll taxes (Social Security and Medicare), sales taxes, property taxes, and excise taxes, the overall picture changes. A middle-income household pays a larger share of their earnings in payroll taxes than a high-income household does, because payroll taxes cap at a certain income level and explore to wages but not investment income.

Key Takeaways

  • The top 1 percent of earners pay roughly 40 percent of all federal income tax, and the top 10 percent pay roughly 70 percent.
  • Federal income tax is progressive, meaning higher earners pay a higher percentage of their income as tax, but the actual dollars collected come mostly from the wealthy.
  • Payroll taxes (Social Security and Medicare) hit middle-income workers harder as a percentage of earnings because they cap at a certain income level.
  • State and local taxes vary widely by location and include property tax, sales tax, and income tax, which change the overall tax burden picture.
  • Corporate taxes have declined as a share of total federal revenue over the past 40 years, even as corporate profits have grown.

How the federal income tax system is structured

The federal income tax uses a progressive tax system, meaning the tax rate increases as income increases. You do not pay the same percentage on every dollar you earn. Instead, your income is divided into brackets, and each bracket has its own rate. For 2024, those brackets range from 10 percent on the lowest income to 37 percent on income above roughly $609,000 for single filers.

Because of this structure, a person earning $1 million pays a much higher percentage of their income in federal tax than someone earning $50,000. The person earning $1 million might pay 35 percent of their income in federal tax, while the person earning $50,000 might pay 12 percent. This is why the wealthy pay the majority of dollars collected—they earn the majority of income and pay higher rates on it.

Why the top earners pay so much in absolute dollars

The concentration of income in the United States means that a small number of people earn a very large share of total income. If the top 1 percent earns roughly 20 to 25 percent of all income in the country, and they pay a higher tax rate on that income, they will naturally pay a large share of total taxes collected. The math is straightforward: more income plus higher rates equals more tax dollars.

This is different from asking whether the tax system is fair or whether rates are too high or too low—those are questions about policy. The fact that the wealthy pay the majority of income tax dollars is straightforward a result of earning the majority of income and paying higher rates on it.

The role of payroll taxes and other federal taxes

Payroll taxes—the 6.2 percent for Social Security and 1.45 percent for Medicare that you see on your paystub—are capped. In 2024, Social Security tax applies only to the first $168,600 of earnings. This means a person earning $200,000 pays the same total Social Security tax as someone earning $500,000. For this reason, payroll taxes take up a larger percentage of a middle-income worker's earnings than a high-income worker's earnings.

Payroll taxes are also split between employer and employee, though economists debate whether the employer portion is truly separate from wages. Together, payroll taxes bring in nearly as much revenue as income taxes do. When you include payroll taxes in the picture, the overall tax burden becomes less concentrated at the top, because middle-income workers pay a significant share.

State and local taxes shift the burden differently

Federal income tax is only part of the story. State income taxes, property taxes, and sales taxes vary dramatically by location. Some states have no income tax at all (Texas, Florida, Nevada, and others), while others tax income at rates up to 13 percent. Property taxes are often the largest tax bill for homeowners and vary from under 0.5 percent of home value in some states to over 2 percent in others.

Sales taxes, which explore to purchases in most states, are regressive—they take up a larger percentage of a low-income person's budget than a high-income person's, because lower-income households spend a larger share of their earnings on taxable goods. A family earning $40,000 might spend 80 percent of it on groceries, gas, and other taxable items, while a family earning $400,000 might spend only 20 percent on those things. This means sales tax hits lower-income households harder as a percentage of earnings.

How corporate taxes fit into the picture

Corporations pay federal income tax on profits, currently at a flat rate of 21 percent. However, corporate tax revenue has declined significantly as a share of total federal revenue. In the 1950s, corporate taxes made up roughly 30 percent of federal revenue. Today, they make up roughly 10 percent, even though corporate profits have grown. This is due to changes in tax law, deductions, and the ability of large corporations to shift profits to lower-tax jurisdictions.

When corporations pay less tax, the burden shifts to individual income taxpayers and payroll taxpayers. Some economists argue this means the wealthy benefit disproportionately, since they own most corporate stock. Others argue that lower corporate taxes encourage investment and job creation, which benefits workers. That debate is about policy, not about the current facts of who pays what.

The difference between tax rate and tax burden

It is important to separate two different questions: What percentage of income does each group pay in tax (the tax rate), and what percentage of total taxes collected comes from each group (the tax burden)? These are not the same thing. The top 1 percent pays a higher tax rate than the bottom 50 percent, and they also pay a larger share of total taxes collected. But the bottom 50 percent, taken together, still pays a meaningful amount in absolute dollars—just a smaller share of the total.

When you hear that "the wealthy pay most of the taxes," that statement is true about federal income tax specifically. When you include all taxes—payroll, state, local, sales, property, and excise taxes—the picture is more mixed. The wealthy still pay a large share, but the burden is more distributed across income levels than federal income tax alone would suggest.

Frequently Asked Questions

Do the wealthy pay their fair share of taxes?

Whether anyone pays their "fair share" is a question about values and policy, not facts. The factual answer is that the top 1 percent pays roughly 40 percent of federal income tax while earning roughly 20 to 25 percent of income. Whether that ratio is fair depends on what you believe the tax system should do.

What percentage of Americans pay no federal income tax?

Roughly 40 percent of households pay no federal income tax in a given year, though this includes people with very low incomes and people who claim deductions that reduce their tax to zero. Most of these households still pay payroll taxes, sales taxes, and property taxes. The percentage varies year to year based on income levels and tax law changes.

Why do some rich people pay less tax than middle-class people?

This happens when someone's income comes mostly from investments rather than wages. Long-term capital gains (profits from selling stocks or property held over a year) are taxed at lower rates than wages—up to 20 percent instead of 37 percent. Someone earning $5 million in capital gains might pay a lower effective tax rate than someone earning $200,000 in wages, even though they earn much more in absolute dollars.

Do corporations pay more or less tax than they used to?

Corporations pay less tax as a share of federal revenue than they did in the 1950s and 1960s, when corporate taxes made up roughly 30 percent of revenue. Today that share is roughly 10 percent. The statutory rate (the official rate in law) has also fallen, from 35 percent before 2017 to 21 percent after. However, the total dollars collected from corporations has not fallen as dramatically because corporate profits have grown.
