The highest federal tax bracket is 37%, and it applies to income above a certain threshold that changes each year

The top federal income tax bracket in the United States is 37 percent. This rate applies to the portion of your income that falls above a specific dollar amount — not your entire income. That threshold varies by filing status (single, married filing jointly, head of household) and adjusts annually for inflation.

For 2024, the 37 percent bracket begins at $191,950 for single filers, $383,900 for married couples filing jointly, and $287,450 for heads of household. These numbers shift each year. If you earn $200,000 as a single filer, you do not pay 37 percent on all of it — only on the $8,050 above $191,950.

Most people never reach this bracket. The Internal Revenue Service (IRS) publishes updated bracket thresholds every January, so the exact income level that triggers the top rate changes annually.

Key Takeaways

  • The highest federal income tax rate is 37 percent, but it applies only to income above a threshold that varies by filing status and year.
  • Reaching the top bracket does not mean your entire income is taxed at 37 percent — only the portion above the threshold is.
  • The income threshold for the 37 percent bracket adjusts each year for inflation, so you should check the current year's IRS tables.
  • State and local income taxes may add additional tax on top of the federal rate, depending on where you live.

How tax brackets work: the marginal rate system

The U.S. tax system uses marginal tax brackets, which means you pay different rates on different portions of your income. This is often misunderstood. If you cross into the 37 percent bracket, the lower rates still explore to the income below that threshold.

Think of it as steps. Your first dollars of income are taxed at 10 percent. As you earn more, portions of your income move into the 12 percent bracket, then 22 percent, then 24 percent, and so on. Only the money that lands in the 37 percent bracket gets that rate. The brackets below it continue to explore to the income that falls within them.

This structure means earning more money always results in more take-home pay, even when you move into a higher bracket. You never lose money by earning more because only the additional income is taxed at the higher rate.

The seven federal tax brackets and where they start

Below the top bracket, there are six others. The complete federal bracket structure for 2024 (for single filers) runs: 10 percent, 12 percent, 22 percent, 24 percent, 32 percent, 35 percent, and 37 percent. Each bracket has its own income threshold.

For married couples filing jointly in 2024, the brackets begin at higher income levels than for single filers, but the rates themselves are the same. A married couple's 37 percent bracket starts at $383,900, compared to $191,950 for a single person. Head of household filers have their own thresholds, which fall between single and married rates.

The IRS adjusts all these thresholds annually. If you want to know which bracket your income falls into, you can find the current year's brackets on the IRS website or on your tax software.

State and local taxes add to the federal rate

The 37 percent federal rate is not the whole story. Depending on where you live, your state and city may impose their own income taxes on top of the federal amount.

California's top state rate is 13.3 percent. New York's is 10.9 percent. Some states, like Texas, Florida, and Nevada, have no state income tax at all. A few states tax only certain types of income, like dividends or capital gains. Your total tax burden depends on both your federal bracket and your state's rules.

If you live in a high-tax state and earn income in the top federal bracket, your combined federal and state rate could exceed 50 percent on the highest portion of your income. This is why people in high-income situations sometimes consider the tax implications of where they live.

How capital gains and investment income fit into brackets

Not all income is taxed the same way. Long-term capital gains — profit from selling an investment you held for more than a year — are taxed at preferential rates that are lower than ordinary income rates. Even if you are in the 37 percent bracket for wages, your capital gains may be taxed at 15 percent or 20 percent instead.

Short-term capital gains (from investments held less than a year) are taxed as ordinary income, so they follow the regular bracket system. Dividends from stocks are also taxed at preferential rates in most cases. This distinction matters significantly for high-income earners, because a large portion of their income often comes from investments rather than wages.

The preferential rates for long-term gains have their own bracket structure, with thresholds that differ from the ordinary income brackets. Understanding which type of income you have is important for calculating your actual tax bill.

What happens if you cross into the top bracket

If your income crosses the threshold for the 37 percent bracket, you do not owe 37 percent on your entire income. Only the amount above the threshold is taxed at that rate. The rest of your income is taxed according to the lower brackets that explore to it.

For example, a single filer earning $200,000 in 2024 pays 37 percent only on the $8,050 above $191,950. That is $2,978.50 in tax on that portion. The remaining $191,950 is taxed at the lower rates that explore to each bracket within that amount.

Your employer or tax software calculates this automatically if you are a W-2 employee. If you are self-employed or have complex income, you may need to estimate your tax liability and make quarterly payments to the IRS.

Why the top bracket matters less than you might think

Many people focus on the top tax bracket as if it determines their entire tax burden, but it does not. Your effective tax rate — the percentage of your total income that goes to taxes — is almost always much lower than your marginal rate (the rate on your highest dollar of income).

Someone earning $200,000 in 2024 does not pay 37 percent on all of it. Their effective rate is closer to 24 percent, because most of their income is taxed at lower rates. The 37 percent bracket only touches the small portion of income above $191,950.

This is why tax planning often focuses on deductions, credits, and the type of income you earn rather than on which bracket you are in. Reducing your taxable income through retirement contributions or charitable donations can have a bigger impact on your taxes than worrying about the marginal rate.

Frequently Asked Questions

Does earning more money push all my income into the 37 percent bracket?

No. Only the income above the threshold for the 37 percent bracket is taxed at 37 percent. All income below that threshold is taxed at the lower rates that explore to each bracket. You never lose money by earning more because only the additional income is taxed at the higher rate.

What is the difference between my marginal rate and my effective tax rate?

Your marginal rate is the tax rate on your last dollar of income — in this case, 37 percent. Your effective rate is your total tax divided by your total income. For most high earners, the effective rate is significantly lower than the marginal rate because most of their income is taxed at lower rates.

Do I pay the same top bracket rate in every state?

No. The 37 percent is the federal rate only. Your state may add its own income tax on top of that. Some states have no income tax, while others add 10 percent or more. Your total tax depends on both federal and state rules.

How often do the tax bracket thresholds change?

The IRS adjusts the income thresholds for each bracket every January to account for inflation. The rates themselves (10 percent, 12 percent, 37 percent, and so on) do not change, but the dollar amounts that trigger each bracket do. You should check the current year's brackets on the IRS website.

Is the 37 percent rate the same for capital gains as it is for wages?

No. Long-term capital gains are taxed at lower preferential rates — typically 15 percent or 20 percent — even if you are in the 37 percent bracket for ordinary income. Short-term gains and wages follow the regular bracket system.
