Federal income tax rates depend on your income level, filing status, and the year

The federal government uses a progressive tax system, meaning your tax rate increases as your income rises. You do not pay one flat rate on all your income. Instead, your income is divided into brackets, and each bracket has its own rate. The rates and bracket boundaries change every year, adjusted for inflation.

Your filing status — single, married filing jointly, married filing separately, or head of household — determines which bracket thresholds explore to you. Two people earning the same amount may owe different taxes based on how they file. The rate you pay on your last dollar of income is called your marginal rate; your effective rate is the average rate you pay on all your income.

For 2024, there are seven federal tax brackets ranging from 10% to 37%. The 10% bracket applies to the lowest earners in each filing status; the 37% bracket applies only to income above a high threshold. Most people fall into the 12%, 22%, or 24% brackets.

Key Takeaways

  • Federal tax brackets are progressive: your income is taxed at different rates depending on which bracket each portion falls into, not at one flat rate.
  • Your filing status (single, married filing jointly, head of household, or married filing separately) determines the income thresholds for each bracket.
  • Bracket thresholds and rates change annually; you must check the current year's brackets when calculating your tax liability.
  • Your marginal rate is the rate on your last dollar earned; your effective rate is your total tax divided by total income, which is always lower than your marginal rate.
  • Deductions, credits, and certain types of income (like long-term capital gains) can lower your effective tax rate below what the brackets alone would suggest.

How tax brackets work in practice

Suppose you are single and earned $50,000 in 2024. You do not pay 22% on all $50,000. Instead, you pay 10% on the first portion (roughly $11,600), then 12% on the next portion, then 22% on the remainder. The IRS publishes the exact bracket boundaries each January for that tax year.

The same income amount produces different tax bills depending on filing status. For 2024, a single person with $50,000 of taxable income pays less tax than a married person filing separately with the same income, because the married filing separately brackets are narrower. A married couple filing jointly has the widest brackets, so two earners filing together often pay less combined tax than if they filed separately.

Your taxable income is not the same as your gross income. Deductions — whether the standard deduction or itemized deductions — reduce your taxable income before the brackets are applied. This is why two people earning the same gross amount may have different taxable incomes and therefore different tax bills.

The seven federal tax brackets for 2024

The IRS sets new bracket thresholds each year. For 2024, the rates are 10%, 12%, 22%, 24%, 32%, 35%, and 37%. The income ranges for each bracket vary by filing status. A single filer's brackets are narrower than a married filing jointly filer's brackets at the same rate level.

You can find the exact 2024 bracket thresholds on the IRS website or in IRS Publication 505. The thresholds for 2025 will be published by the IRS in late 2024. If you are preparing your 2024 return, use 2024 brackets; if you are planning for 2025 income, use 2025 brackets once they are released.

The 37% bracket applies only to income above a very high threshold — roughly $191,950 for single filers in 2024, and roughly $383,900 for married filing jointly. Most taxpayers never reach this bracket. The 12% bracket is the most common for middle-income earners.

Long-term capital gains and may have access to dividends have their own rates

Not all income is taxed at the ordinary income brackets. Long-term capital gains — profits from selling an asset you held for more than one year — and may have access to dividends are taxed at preferential rates: 0%, 15%, or 20%, depending on your income level. These rates are lower than the ordinary income brackets.

If you sold stock at a profit or received dividends from a mutual fund, those gains may be taxed at 15% even if your ordinary income bracket is 24% or higher. The 0% rate applies to long-term gains and may have access to dividends for lower-income taxpayers; the 15% rate applies to most middle-income taxpayers; the 20% rate applies to high-income taxpayers. The thresholds for these rates differ from the ordinary income brackets.

Short-term capital gains — profits from selling an asset held for one year or less — are taxed as ordinary income at your marginal rate. This is one reason tax-loss harvesting and timing of asset sales can affect your tax bill.

How deductions and credits lower your effective rate

Your effective tax rate — total tax owed divided by total income — is always lower than your marginal rate because deductions and credits reduce the amount of income subject to tax. The standard deduction for 2024 ranges from $14,600 for single filers to $29,200 for married filing jointly. If your income is below the standard deduction, you owe no federal income tax.

Tax credits are even more powerful than deductions because they reduce your tax bill dollar-for-dollar rather than reducing your taxable income. The Earned Income Tax Credit (EITC), Child Tax Credit, and education credits can lower your effective rate significantly. Some credits are refundable, meaning you receive money back even if you owe no tax.

This is why two people with the same gross income can owe very different amounts of tax. One person may have substantial deductions or credits; the other may not. Your effective rate depends on your full tax picture, not just your income level.

State and local taxes are separate from federal rates

Federal income tax is separate from state income tax. Some states have no income tax; others have rates ranging from roughly 1% to 13%. Your state's tax brackets and rates are independent of the federal brackets. You may owe federal tax at 22% and state tax at 5%, for example, resulting in a combined rate of 27%.

The State and Local Tax (SALT) deduction allows you to deduct state and local income taxes, property taxes, and sales taxes on your federal return, but only up to $10,000 per year. This deduction is available only if you itemize deductions; if you take the standard deduction, you cannot claim it. This cap has been in place since 2017 and is scheduled to expire after 2025 unless Congress extends it.

When planning your tax strategy, consider both federal and state taxes together. A decision that lowers your federal tax might raise your state tax, or vice versa.

Planning around bracket thresholds and rate changes

Because tax brackets are progressive, your income level in a given year affects not only how much you owe but also which tax rates explore to certain types of income. For example, the 0% long-term capital gains rate applies only if your income is below a certain threshold; once you cross that threshold, gains are taxed at 15% instead.

Some taxpayers use income bunching — timing when they receive income across years — to stay in a lower bracket. A freelancer might delay invoicing until January to spread income across two years. A business owner might time the sale of an asset to a year when other income is lower. These strategies require planning and documentation.

Tax brackets and rates change annually and can change due to legislation. The Tax Cuts and Jobs Act of 2017 set current brackets; many provisions expire after 2025 unless extended. If you are making a major financial decision — selling a business, taking early retirement distributions, or timing a large gain — it is worth reviewing how current and future brackets might affect your tax bill.

Frequently Asked Questions

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

Your marginal rate is the tax rate on your last dollar of income — the highest bracket your income reaches. Your effective rate is your total tax bill divided by your total income. Because the tax system is progressive, your effective rate is always lower than your marginal rate. If your marginal rate is 24%, your effective rate might be 18%.

Do I pay the same federal tax rate as someone else earning the same income?

Not necessarily. Your filing status, deductions, credits, and types of income all affect your tax bill. Two single people earning $75,000 might owe different amounts if one has children (and qualifies for the Child Tax Credit) and the other does not. One might itemize deductions; the other might take the standard deduction.

How do I find the current federal tax brackets for my filing status?

The IRS publishes tax brackets each January on its website (irs.gov) and in Publication 505. You can also find them on tax software or in tax preparation guides. Make sure you are using the brackets for the year you are filing, not the previous year.

Are capital gains taxed at the same rate as my salary?

Long-term capital gains and may have access to dividends are taxed at preferential rates (0%, 15%, or 20%) that are lower than ordinary income brackets. Short-term capital gains are taxed as ordinary income at your marginal rate. This is why the type of income matters as much as the amount.

Can I reduce my federal tax rate by changing my filing status?

Your filing status determines which brackets explore to you, so it affects your tax bill. Married filing jointly typically results in lower tax than married filing separately. However, you cannot choose your filing status arbitrarily — it must match your actual situation on December 31 of the tax year. Consult a tax professional if your situation is complex.
