How Federal Income Tax Brackets Work
Understand marginal tax rates, taxable income, and progressive taxation with a simple example that shows how your federal income tax is calculated.
Federal income tax brackets can sound confusing when you first encounter rates such as 10%, 12%, 22%, and 24%. One common misunderstanding is that moving into a higher bracket means the government taxes your entire income at that higher rate.
That is not how the federal income tax brackets work. Instead, each rate generally applies only to the part of your taxable income that falls within its range. Understanding this system can help you read your paycheck, plan your finances, and make more sense of a tax estimate.
What Are Federal Income Tax Brackets?
Federal income tax brackets are ranges of taxable income associated with specific federal income tax rates. The rates for ordinary income in 2026 are 10%, 12%, 22%, 24%, 32%, 35%, and 37%.
The system is progressive: as taxable income rises, the next portion of income may be taxed at a higher rate. Lower portions remain subject to the rates that apply to their respective brackets.
These brackets apply to federal income tax on ordinary taxable income. They do not, by themselves, determine your entire tax bill. Payroll taxes, certain investment-income taxes, tax credits, deductions, and other rules may affect your final result.
What Is a Marginal Tax Rate?
Your marginal tax rate is the rate that applies to the next dollar of ordinary taxable income, based on your current taxable income and filing status.
For example, a single filer with $60,000 of taxable income in 2026 falls in the 22% marginal tax bracket. That does not mean every dollar is taxed at 22%. The lower portions are taxed at the applicable 10% and 12% rates, while only the portion above the 22% threshold is taxed at 22%.
Moving into a higher federal tax bracket generally changes the rate on the additional taxable income in that bracket, not the rate on all your previous income.
A Simple Example: $60,000 of Taxable Income
Suppose you are single and have $60,000 in taxable income for 2026. To illustrate how the ordinary federal income tax brackets work, split that income into the following portions.
$60,000 taxable income
In this example, the taxpayer’s marginal tax rate is 22%, but the illustrative tax amount is $7,912, which is about 13.2% of the $60,000 taxable income.
This calculation uses the ordinary 2026 rate brackets and assumes the $60,000 is already taxable income. It is a simplified illustration, not a complete tax-return calculation. Tax credits, special tax rules, and other adjustments can change the final amount.
2026 Federal Income Tax Brackets
The following table shows the 2026 federal ordinary income tax brackets for three common filing statuses. The figures are taxable-income thresholds, not gross salary thresholds.
| Tax rate | Single | Married filing jointly | Head of household |
|---|---|---|---|
| 10% | $0–$12,400 | $0–$24,800 | $0–$17,700 |
| 12% | $12,400–$50,400 | $24,800–$100,800 | $17,700–$67,450 |
| 22% | $50,400–$105,700 | $100,800–$211,400 | $67,450–$105,700 |
| 24% | $105,700–$201,775 | $211,400–$403,550 | $105,700–$201,775 |
| 32% | $201,775–$256,225 | $403,550–$512,450 | $201,775–$256,200 |
| 35% | $256,225–$640,600 | $512,450–$768,700 | $256,200–$640,600 |
| 37% | Over $640,600 | Over $768,700 | Over $640,600 |
Thresholds are rounded to readable dollar amounts. For exact tax calculations, including the applicable boundary rules and married filing separately, consult the IRS’s official federal income tax rates and brackets page and the relevant 2026 tax instructions.
Taxable Income Is Not the Same as Salary
Your salary or total income is not necessarily the amount used to determine your federal income tax bracket. The brackets apply to taxable income, which is generally calculated after allowable deductions.
Consider wages and any other income that must be included on your return.
Eligible adjustments may reduce the income used to calculate adjusted gross income.
The standard deduction or eligible itemized deductions generally reduce the amount subject to federal income tax.
The progressive rates apply to the resulting taxable income, subject to applicable tax rules.
For example, two people with the same salary may have different taxable incomes because of filing status, deductions, adjustments, or other circumstances. Their final tax bills may also differ because of credits and other tax rules.
Why Filing Status Matters
Your filing status determines which set of federal income tax thresholds applies to your return. The main statuses are:
- Single: generally for unmarried taxpayers who do not qualify for another status.
- Married filing jointly: generally for eligible married couples who file a joint return.
- Married filing separately: for eligible married taxpayers who file separate returns.
- Head of household: for taxpayers who meet specific requirements, including qualifying household and dependent-related rules.
- Qualifying surviving spouse: available to eligible taxpayers who meet the applicable requirements.
Do not choose a filing status only because it gives you a wider bracket. Eligibility rules apply, and filing status can affect deductions, credits, and other parts of your return. Review the IRS’s filing status guidance if you are unsure.
Marginal Tax Rate vs. Effective Tax Rate
These two terms describe different things.
The next dollar
The tax rate that applies to the next dollar of ordinary taxable income in your current bracket.
The overall picture
A measure of tax divided by a chosen income figure. The result depends on which taxes and which income measure are included.
In the $60,000 example above, the marginal rate is 22%. The illustrative regular federal income tax divided by taxable income is about 13.2%. This is not necessarily the effective rate on total household income or the overall rate after payroll taxes and other taxes.
Do Tax Brackets Change Every Year?
Federal tax brackets are generally adjusted annually for inflation and may also change when tax laws change. This means the thresholds for one tax year may not be the same as the thresholds for another.
Always use the brackets for the tax year you are calculating. A return filed in 2026 may report income earned in 2025, while estimated payments made during 2026 generally relate to 2026 income. Those are different tax-year situations.
Common Tax Bracket Mistakes to Avoid
- Assuming all income is taxed at your highest rate. Progressive brackets apply different rates to different portions of taxable income.
- Using salary instead of taxable income. Deductions and adjustments can change the amount that reaches the brackets.
- Using the wrong tax year. Check whether your question relates to 2025 income or 2026 income.
- Ignoring filing status. Different filing statuses have different thresholds.
- Confusing income tax with total taxes. Social Security and Medicare taxes, state taxes, and other taxes are separate considerations.
- Assuming a higher salary always reduces take-home pay. A higher marginal bracket does not automatically mean you lose money by earning more; only the applicable additional income is taxed at the higher marginal rate.
Frequently Asked Questions
Do I pay the higher tax rate on all my income when I enter a new bracket?
No. Under the progressive federal income tax system, each rate generally applies only to the portion of taxable income within that bracket. Income in lower brackets keeps its lower rate.
What are the federal income tax rates for 2026?
The seven ordinary federal income tax rates for 2026 are 10%, 12%, 22%, 24%, 32%, 35%, and 37%. The income thresholds depend on filing status.
What is the difference between gross income and taxable income?
Gross income generally refers to income before applicable adjustments and deductions. Taxable income is the amount used to calculate regular federal income tax after allowable deductions and other applicable rules.
Can a raise put me in a higher tax bracket?
Yes. A raise can push some of your taxable income into a higher marginal bracket. That does not mean all your taxable income is taxed at the new rate.
Are federal income tax brackets the same for every filing status?
No. The thresholds differ by filing status. Single, married filing jointly, married filing separately, head of household, and qualifying surviving spouse rules should be checked as applicable.
Do federal tax brackets include state income tax?
No. Federal income tax brackets describe federal income tax rates. State and local income taxes, where applicable, are separate and depend on the relevant jurisdiction.
Where can I check the official tax brackets?
Use the IRS’s Federal Income Tax Rates and Brackets page and the official guidance for the tax year you need.
Final Thoughts
Federal income tax brackets are easier to understand once you remember that the system works in layers. Your marginal rate applies to the next portion of taxable income, while lower portions are taxed at the rates assigned to their own brackets.
To make a more useful estimate, identify the correct tax year, confirm your filing status, calculate taxable income, and then consider deductions, credits, and other taxes that may apply to your situation.
