How to Use This Income Tax Calculator
Follow these five steps to get a clean estimate.
- Choose your filing status. Single, married filing jointly, head of household, and married filing separately each have their own brackets and standard deduction.
- Enter your gross annual income. This is your total pay before taxes and deductions, not your take home pay.
- Enter pre tax contributions. Add 401k contributions, health premiums paid through payroll, and similar amounts that lower taxable income.
- Check the standard deduction. This income tax calculator applies the 2026 standard deduction for your status automatically.
- Read your result. You see taxable income, estimated federal tax, your marginal bracket, and your effective rate on gross income.
This income tax calculator updates as you type, so you can test a raise, a larger 401k contribution, or a different filing status and watch the estimate move.
How Federal Income Tax Works in 2026
Federal income tax is progressive, which means different slices of your income are taxed at different rates. Your marginal rate is the rate on your last dollar of taxable income. Your effective rate is your total tax divided by your gross income, and it is almost always lower than your marginal rate.
Taxable income is the figure the brackets actually apply to. Start with gross income, subtract pre tax contributions to get adjusted gross income, then subtract the standard deduction or your itemized deductions. Only the amount left after those steps is taxed using the bracket tables below.
The 2026 rates are 10 percent, 12 percent, 22 percent, 24 percent, 32 percent, 35 percent, and 37 percent. Those rates did not change from recent years. The thresholds moved up with inflation, and the standard deduction rose to 16,100 dollars for single filers and 32,200 dollars for married couples filing jointly, under IRS Revenue Procedure 2025-32.
The 2026 Brackets and Standard Deduction
Use this table to see where your taxable income lands. Each rate applies only to the slice inside its range, never to your whole income.
| Filing status | Standard deduction | 10 percent up to | 12 percent up to | 22 percent up to | 24 percent up to | 32 percent up to | 35 percent up to | 37 percent above |
|---|---|---|---|---|---|---|---|---|
| Single | 16,100 dollars | 12,400 dollars | 50,400 dollars | 105,700 dollars | 201,775 dollars | 256,225 dollars | 640,600 dollars | 640,600 dollars |
| Married filing jointly | 32,200 dollars | 24,800 dollars | 100,800 dollars | 211,400 dollars | 403,550 dollars | 512,450 dollars | 768,700 dollars | 768,700 dollars |
| Head of household | 24,150 dollars | 17,700 dollars | 67,450 dollars | 105,700 dollars | 201,775 dollars | 256,200 dollars | 640,600 dollars | 640,600 dollars |
| Married filing separately | 16,100 dollars | 12,400 dollars | 50,400 dollars | 105,700 dollars | 201,775 dollars | 256,225 dollars | 384,350 dollars | 384,350 dollars |
If you itemize and your itemized total beats your standard deduction, use the itemized figure instead. Most filers take the standard deduction, because it needs no receipts and no extra forms.
Worked Example: Sarah and Her 85,000 Dollar Salary
Sarah is single, earns 85,000 dollars a year in Texas, and puts 5,000 dollars into her 401k through payroll. Here is her math, step by step.
First, subtract pre tax contributions from gross income. 85,000 dollars less 5,000 dollars gives adjusted gross income of 80,000 dollars. Next, subtract the single standard deduction of 16,100 dollars. That leaves taxable income of 63,900 dollars.
Now apply the single brackets to 63,900 dollars of taxable income. The first 12,400 dollars are taxed at 10 percent, which is 1,240 dollars. The next 38,000 dollars, from 12,401 dollars to 50,400 dollars, are taxed at 12 percent, which is 4,560 dollars. The remaining 13,500 dollars, from 50,401 dollars to 63,900 dollars, are taxed at 22 percent, which is 2,970 dollars.
Add the three slices together. 1,240 dollars plus 4,560 dollars plus 2,970 dollars equals an estimated federal tax of 8,770 dollars. Her marginal bracket is 22 percent, because that is the rate on her last dollar. Her effective rate on gross income is 10.32 percent, which is 8,770 dollars divided by 85,000 dollars. Spread over the year, that is about 730.83 dollars per month in federal tax.
Enter Sarah’s exact inputs in the income tax calculator above, single status, 85,000 dollars gross, 5,000 dollars pre tax, and you must see the same result: taxable income 63,900 dollars, federal tax 8,770 dollars, marginal bracket 22 percent, effective rate 10.32 percent.
Income Tax Estimate Versus Paycheck Take Home Pay
An annual federal tax estimate and a per check paycheck figure answer different questions, and it helps to know which one you need.
| Question | Best tool | What you get |
|---|---|---|
| What is my federal tax for the year | This page | Estimated annual federal tax, taxable income, marginal bracket, effective rate |
| What lands in my bank account each payday | Paycheck calculator | Net pay per check, per month, and per year, after federal tax, state tax, Social Security, and Medicare |
| What sales tax do I pay on a purchase | Sales tax calculator | Tax added to a price, or the pre tax price hidden inside a total |
If you are comparing job offers, start here for the annual federal picture, then run the paycheck calculator to see each payday. The two tools use the same 2026 federal figures, so their federal tax lines should tell a consistent story.
Common Mistakes That Inflate Your Estimate
Avoid these five mistakes when you use an income tax calculator to estimate federal tax.
First, do not apply your marginal rate to your whole income. A 22 percent bracket does not mean 22 percent of everything you earn. Only the slice inside that bracket is taxed at 22 percent.
Second, do not tax your gross salary directly. Pre tax contributions and the standard deduction come off first, and they can move thousands of dollars out of taxable income.
Third, do not forget that this estimate covers federal tax only. State tax, Social Security, and Medicare are separate lines on a pay stub, and they are not in this result.
Fourth, do not mix tax years. These brackets and deductions are for income earned in 2026, reported on returns filed in 2027. Older tables will give you the wrong answer.
Fifth, do not treat the estimate as a refund prediction. A refund depends on how much was withheld during the year. If withholding beat the tax bill, the difference comes back as a refund. If withholding fell short, the balance is owed.
How Withholding Relates to Your Tax Bill
Your tax bill and your refund are two different numbers, and mixing them up causes most tax season surprises. The estimate on this page is your tax bill for the year. Withholding is the amount your employer already sent to the IRS from your paychecks during the year. The return compares the two.
If withholding is larger than the bill, the IRS refunds the difference. If withholding is smaller, you owe the balance when you file. Neither outcome means the tax itself changed. It only means the payments during the year did not match the final bill.
Use this income tax calculator early in the year to check withholding, not just in April. If the estimate is well above what your pay stubs show as withheld so far, you may be heading for a balance due. If it is well below, you may be giving the IRS a free loan each payday and could adjust withholding instead. Any change to withholding goes through Form W4 with your employer, and it takes effect on future paychecks only.
What Moves Your Bill the Most
Four inputs move a federal estimate more than anything else. First is filing status, because joint brackets are roughly double the single brackets and the joint standard deduction is double as well. Second is pre tax saving, because every dollar contributed through payroll lowers taxable income by a dollar, saving tax at your marginal rate.
Third is extra income. A side job, a bonus, or freelance pay stacks on top of your salary income, and those top dollars are taxed at your highest marginal rate, not your average rate. Fourth is credits. Unlike deductions, which lower taxable income, credits lower the tax bill directly, dollar for dollar, so a credit can move the final figure more than a deduction of the same size. This income tax calculator does not model credits, which is why the result is an estimate of tax before credits, not a final return figure.
Frequently Asked Questions
What does this tool estimate?
This income tax calculator estimates your federal income tax for 2026 from your gross income, pre tax contributions, and filing status, using the IRS brackets and standard deduction.
Is this federal tax only?
Yes. The result covers federal income tax only. It does not include state income tax, Social Security, Medicare, or local taxes.
Why is my effective rate lower than my bracket?
Your bracket is the rate on your last dollar only. Lower slices of income are taxed at lower rates, and the standard deduction shelters part of your income entirely, so your average rate across all income sits below your top rate.
Does it include state tax?
No. State tax rules vary widely, and some states have no income tax at all. Add your state estimate separately, or use a state paycheck page to see the combined picture.
What if I itemize deductions?
If your itemized deductions beat your standard deduction, your taxable income is lower than this tool shows. Enter the difference as an extra pre tax amount to approximate the result, or use the itemized total in place of the standard deduction.
How do pre tax contributions change my tax?
They lower adjusted gross income before brackets apply. In Sarah’s example, a 5,000 dollar 401k contribution cut taxable income by the full 5,000 dollars and cut her federal tax by 1,100 dollars at her 22 percent marginal rate.
What filing status should I choose?
Use the status you expect to file with. Single applies to unmarried filers. Married filing jointly usually gives the widest brackets and the largest standard deduction for couples. Head of household applies to unmarried filers who pay more than half the cost of keeping up a home for a qualifying person.
Does it handle capital gains or business income?
No. This tool covers ordinary wage and salary income taxed at the regular rates. Capital gains use a separate rate schedule, and business income has its own rules and deductions.
How accurate is this estimate?
It is exact for the inputs you enter under the stated assumptions: ordinary income only, standard deduction, no credits, no extra adjustments. Credits, extra income, and itemized deductions move the final return figure.
When do the 2026 brackets apply?
They apply to income earned during calendar year 2026, which is reported on the return filed in early 2027. If you are estimating tax on 2025 income, use the 2025 tables instead.
