The top 1% pays about 40% of all federal income tax

The wealthiest Americans pay a much larger share of total federal income tax than middle-income or lower-income households. The top 1% of earners—those making roughly $600,000 or more per year, though this threshold shifts annually—pay around 40% of all federal income tax collected. The top 10% pay roughly 70%. This concentration at the top means that the bottom 50% of earners pay only about 3% of federal income tax.

These numbers describe federal income tax only. They do not include payroll taxes (Social Security and Medicare), state and local taxes, sales taxes, or property taxes. The picture changes when you add those other taxes, because payroll taxes hit middle-income workers harder relative to their income, and sales taxes take a larger bite from lower-income households.

The reason the top earners pay such a large share is straightforward: they earn a much larger share of total income. The top 1% earns roughly 20% of all income in the United States. When you earn more, you pay more tax at the same rate. But the federal income tax is also progressive—the tax rate rises as your income rises—so high earners pay a higher percentage of their income in tax than lower earners do.

Key Takeaways

  • The top 1% of earners pays about 40% of all federal income tax, while the bottom 50% pays about 3%.
  • This concentration happens because the top 1% earns about 20% of all income and faces higher tax rates on that income.
  • Federal income tax is only one type of tax; payroll taxes, sales taxes, and property taxes create a different picture of who bears the overall tax burden.
  • The share paid by high earners has grown over the past 30 years as income inequality has widened.

How the progressive tax system works

The U.S. federal income tax uses tax brackets. You do not pay one flat rate on all your income. Instead, your income is divided into chunks, and each chunk is taxed at a different rate. For 2024, a single filer pays 10% on the first roughly $11,600, then 12% on income from $11,600 to $47,150, then 22% on the next chunk, and so on up to 37% on income above $578,100.

This means a person earning $100,000 does not pay 22% on all $100,000. They pay 10% on the first $11,600, 12% on the next $35,550, 22% on the next $41,775, and 24% on the remaining $11,075. Their effective tax rate—the actual percentage of their total income that goes to federal income tax—is lower than their highest bracket rate.

High earners pay a higher effective rate because more of their income falls into the higher brackets. Someone earning $1 million has much more income in the 35% and 37% brackets. This is why the top 1% pays such a large share of total tax: they earn vastly more income, and a larger portion of it is taxed at higher rates.

Income inequality drives the tax concentration

The share of federal income tax paid by the top earners has grown significantly since the 1980s, not because tax rates on the rich have risen—they have actually fallen—but because income inequality has widened. In 1980, the top 1% earned about 8% of all income. By 2023, they earned roughly 20%. The top 10% earned about 33% of income in 1980 and roughly 50% today.

When income becomes more concentrated at the top, tax revenue becomes more concentrated at the top as well, even if tax rates stay the same. A progressive tax system naturally produces this result: as the wealthy earn a larger share of total income, they automatically pay a larger share of total tax.

This does not mean the wealthy pay higher tax rates than they did in the 1980s. The top marginal tax rate was 70% in 1980 and is 37% today. But because the wealthy now earn so much more of the nation's total income, they still pay a much larger dollar amount and a larger share of the total.

Payroll taxes tell a different story

Federal income tax is only part of what Americans pay. Payroll taxes—the 6.2% for Social Security and 1.45% for Medicare that you see on your pay stub, plus the matching amount your employer pays—are a much larger burden on middle-income and lower-income workers.

Payroll taxes are not progressive. Everyone pays the same 6.2% rate on wages up to a cap (roughly $168,600 in 2024). A person earning $50,000 pays 6.2% on all $50,000. A person earning $500,000 pays 6.2% on only the first $168,600 and nothing on the remaining $331,400. This makes payroll taxes regressive—they take a larger percentage from lower earners.

When you add payroll taxes to income taxes, the tax burden becomes less concentrated at the top. Middle-income workers pay a much larger share of their income in total federal taxes than the income tax numbers alone suggest. A household earning $75,000 might pay roughly 15% of income in combined federal income and payroll taxes, while a household earning $500,000 might pay roughly 25%—still higher, but not as dramatically higher as income tax alone would show.

State and local taxes shift the burden further

State income taxes, sales taxes, and property taxes vary widely by location, but they generally take a larger bite from lower-income households as a percentage of income. Sales taxes are the clearest example: a 7% sales tax on a $30 purchase is the same whether you earn $30,000 or $300,000 per year, but it represents a much larger share of the lower earner's income.

Property taxes are usually tied to home value, so they do concentrate more at higher income levels. But in many states, property tax rates are capped or assessed in ways that protect long-term homeowners, which can mean a middle-class homeowner pays more in property tax relative to income than a wealthy person in a neighboring state.

When you add all taxes together—federal income, payroll, state income, sales, and property—the overall tax system is much less progressive than federal income tax alone. Some research suggests the total tax burden is nearly flat across income levels, or even slightly regressive at the very top, depending on the state.

Corporate taxes and capital gains complicate the picture

The federal government also collects corporate income tax and taxes on investment income (capital gains and dividends). These taxes are paid by corporations and by wealthy individuals who earn most of their income from investments rather than wages.

Corporate tax revenue has fallen as a share of total federal revenue over the past 40 years. In the 1980s, corporate taxes made up about 2% of GDP; today they make up about 1%. This shift means that more of the tax burden has moved to individual income and payroll taxes.

Capital gains—profits from selling investments—are taxed at lower rates than wages. Long-term capital gains (investments held over a year) are taxed at 0%, 15%, or 20% depending on income, while ordinary income is taxed at rates up to 37%. Because wealthy people earn a much larger share of their income from investments, this lower rate on capital gains reduces the effective tax rate on the wealthy.

How tax policy has changed over time

The share of federal income tax paid by the top earners has fluctuated with changes in tax law. The Tax Cuts and Jobs Act of 2017 lowered the top marginal rate from 39.6% to 37% and reduced rates across the board. This reduced the share of tax paid by the top earners in the short term, though the effect was partly offset by rising incomes at the top.

Before 2017, the top marginal rate had been 39.6% since 1993. In the 1980s under President Reagan, the top rate fell from 70% to 28%, then rose again in the 1990s. These changes affect how much tax high earners pay, but they do not change the fundamental fact that a progressive system with rising incomes at the top will produce a concentration of tax revenue at the top.

Tax policy continues to shift. Understanding who pays what requires looking at the current tax code, not assumptions about how taxes work in general. The brackets, rates, and caps change nearly every year, and special provisions (deductions, credits, exclusions) create different effective rates for different types of income.

Frequently Asked Questions

Do the wealthy pay their fair share of taxes?

This is a values question, not a factual one. The facts are: the top 1% pays about 40% of federal income tax while earning about 20% of income, and the top 10% pays about 70% while earning about 50% of income. Whether that is fair depends on what you believe the tax system should do. Some argue the wealthy should pay more; others argue they already pay a disproportionate share.

Why do some wealthy people pay less tax than middle-income people?

This happens when someone's income comes mostly from capital gains, which are taxed at lower rates than wages, or when they use deductions and credits to reduce taxable income. A billionaire whose wealth comes from stock appreciation might pay less in annual income tax than a doctor earning $300,000 in wages, because the billionaire has not sold the stock and realized the gain.

How much do the middle class pay in taxes?

A household in the middle 50% of income earners pays roughly 3% of federal income tax but roughly 15% to 20% of total federal taxes when you include payroll taxes. The exact amount depends on income level, family size, and what state you live in. Middle-income households typically pay an effective federal tax rate of 10% to 15% when all taxes are combined.

Is the U.S. tax system more or less progressive than other countries?

The U.S. federal income tax is progressive, but when you add payroll taxes, state taxes, and local taxes, the overall system is less progressive than in many other developed countries. Some European countries have higher top marginal rates and fewer deductions, making their systems more progressive overall.

What percentage of Americans pay no federal income tax?

In recent years, roughly 40% of households pay no federal income tax, though most of them still pay payroll taxes if they work. These households have incomes below the standard deduction or have enough credits to eliminate their tax liability. This does not mean they pay no taxes—they pay sales tax, property tax, and payroll tax.
