Calculate your federal income tax
Find Out How Much Federal Income Tax You May Owe
Enter your expected 2026 income, filing status and deductions to estimate your federal income tax. See how much of your income falls into each tax bracket, your average tax rate and whether your payments may cover your estimated bill.
Designed for common individual income tax situations. Calculations run in your browser; no account or personal identifying information is required.
Enter your 2026 tax details
Start with the basic information. Optional fields help refine your estimate.
Deduction details
Enter amounts that are deductible for federal tax purposes, not every amount taken out of a paycheck.
For the age/blind field, count one addition for each qualifying age or blindness condition. Joint filers can have up to four; most other filers can have up to two. The extra standard deduction applies only when using the standard deduction. Enter any eligible enhanced senior deduction separately in the other-deductions field after checking its phaseout.
Refund or payment planning
These payments affect your projected balance, not the amount of income tax calculated.
This is a simplified regular federal income tax estimator. Ordinary income only; see limitations below for capital gains, self-employment tax, refundable credits and special taxes.
Quick explanation
How the Federal Income Tax Calculator Works
Federal income tax is based on taxable income, not simply your annual salary. The calculator first estimates adjusted gross income, subtracts applicable deductions, applies the 2026 progressive tax brackets and then subtracts the eligible nonrefundable tax credits you entered.
Enter income
Use expected annual income subject to ordinary federal rates. If entering wages, generally use taxable wage amounts rather than assuming all gross compensation is taxable.
Subtract deductions
Choose the standard deduction or provide eligible itemized deductions. Enter permitted adjustments and additional deductions separately.
Apply brackets and credits
The calculator taxes each income layer at the appropriate percentage, subtracts nonrefundable credits, and compares the result with payments entered.
What your results mean
Marginal tax rate is the rate on the next dollar of ordinary taxable income. Effective federal income tax rate is estimated federal income tax after entered credits divided by gross income. The effective rate is usually lower than the marginal rate.
Projected refund or amount owed compares entered federal income tax withholding and estimated payments with the estimated tax liability. A refund does not mean you paid no tax—it generally means your payments exceeded your liability, subject to credits and tax items this tool does not model.

2026 Federal Income Tax Brackets and Rates
The IRS uses seven ordinary federal tax rates: 10%, 12%, 22%, 24%, 32%, 35% and 37%. The taxable income thresholds change according to filing status.
| Rate | Single | Married jointly | Married separately | Head of household |
|---|---|---|---|---|
| 10% | $0–$12,400 | $0–$24,800 | $0–$12,400 | $0–$17,700 |
| 12% | $12,400–$50,400 | $24,800–$100,800 | $12,400–$50,400 | $17,700–$67,450 |
| 22% | $50,400–$105,700 | $100,800–$211,400 | $50,400–$105,700 | $67,450–$105,700 |
| 24% | $105,700–$201,775 | $211,400–$403,550 | $105,700–$201,775 | $105,700–$201,750 |
| 32% | $201,775–$256,225 | $403,550–$512,450 | $201,775–$256,225 | $201,750–$256,200 |
| 35% | $256,225–$640,600 | $512,450–$768,700 | $256,225–$384,350 | $256,200–$640,600 |
| 37% | Over $640,600 | Over $768,700 | Over $384,350 | Over $640,600 |
The figures show taxable-income intervals, not total salary. At bracket boundaries, the next portion of taxable income is taxed at the higher rate. Source: IRS 2026 tax rate schedules and Publication 505.
Marginal vs. effective tax rate
Marginal rate
Used on the next dollar of ordinary taxable income. It can change when taxable income crosses a threshold.
Effective rate
Measures how much of your gross income goes toward the estimated federal income tax shown by this calculator.
Worked example
Federal Income Tax Example: $80,000 Income in 2026
Consider a single filer under 65 with $80,000 of ordinary income, no adjustments, no additional deductions and no tax credits. Using the $16,100 standard deduction, taxable income is $63,900.
| Calculation layer | Amount taxed | Rate | Tax |
|---|---|---|---|
| First taxable income layer | $12,400 | 10% | $1,240 |
| Second layer | $38,000 | 12% | $4,560 |
| Remaining layer | $13,500 | 22% | $2,970 |
| Total estimated income tax | $63,900 taxable | — | $8,770 |
Federal income tax
Before any credits or special taxes.
Marginal rate
The rate on the next dollar of ordinary taxable income.
Effective rate
$8,770 divided by $80,000 gross income.
If the individual had $9,500 of federal income tax withheld, this simplified calculation would indicate a potential $730 refund before any other federal tax items or payments.
Lower taxable income
2026 Federal Standard Deduction vs. Itemized Deductions
The standard deduction is a fixed amount based primarily on filing status, with certain additional amounts for age or blindness. Itemizing means claiming qualifying individual expenses under IRS rules instead.
| Filing status | 2026 basic standard deduction |
|---|---|
| Single | $16,100 |
| Married filing jointly | $32,200 |
| Married filing separately | $16,100 |
| Head of household | $24,150 |
When itemizing may help
Itemizing can be more beneficial if allowable expenses exceed your standard deduction. Common categories include qualifying mortgage interest, certain state and local taxes, eligible charitable contributions and medical expenses above the applicable percentage-of-AGI threshold. Each has its own conditions and limits.
Additional standard deduction for age 65 or blindness
For 2026, the additional standard deduction is generally $2,050 for each eligible age/blindness condition for unmarried filers, and $1,650 per condition for married filers. It is separate from the newer enhanced senior deduction. Special eligibility rules apply, including restrictions for taxpayers claimed as dependents and certain married-filing-separately situations.
Tax deductions are not the same as tax credits
A $1,000 deduction reduces taxable income by $1,000. Its tax-saving value depends on the applicable tax bracket. An eligible $1,000 nonrefundable credit can instead reduce tax liability by up to $1,000. Credits can therefore be more valuable dollar for dollar.
Tax savings
Federal Tax Credits to Consider in 2026
The calculator includes an input for eligible nonrefundable credits. Enter only credits you have already determined you qualify for. Not every credit is fully available to every taxpayer, and refundable credits require different treatment.
Child Tax Credit
For 2026, the maximum credit is generally $2,200 per qualifying child under age 17, subject to eligibility rules, Social Security number requirements and income-based phaseouts. The refundable Additional Child Tax Credit is not automatically calculated here.
Other Dependent Credit
Certain dependents who do not qualify for the Child Tax Credit may qualify for a credit of up to $500, subject to applicable requirements.
Education tax credits
Eligible students or taxpayers may qualify for education benefits such as the American Opportunity Tax Credit or Lifetime Learning Credit. Income limits and qualifying expenses matter.
Retirement and other credits
Depending on your situation, retirement contribution, dependent care, foreign tax or other credits may apply. Some are nonrefundable; others have refundable components.
Tax payment planning
Estimate Your Federal Tax Refund or Balance Owed
Federal income tax withheld from paychecks and estimated tax payments are prepayments of your annual federal tax liability. The amount owed or refunded generally becomes clear when your annual tax return accounts for tax, credits and all payments.
If payments exceed estimated tax
The calculator displays a potential refund. Verify that your entered withholding represents the entire tax year, not merely payments already made as of today.
If estimated tax exceeds payments
The calculator displays a projected amount owed. Additional payments, qualifying refundable credits or taxes outside the estimator can change the final balance.
How to check federal withholding with the IRS
- Gather recent pay statements. Find year-to-date federal income tax withheld, expected annual wages and details for all jobs.
- Open the IRS Tax Withholding Estimator. Follow the IRS questions about filing status, income, tax withholding, deductions and credits.
- Compare the IRS estimate with this calculation. The official estimator can address paycheck withholding details and tax provisions not modeled here.
- Review Form W-4 if necessary. Submit updated withholding instructions through your employer or payroll system, not through this independent website.
If you have nonwage income or insufficient withholding, check IRS estimated tax payment guidance. A payment schedule may be necessary even if you expect to file your return the following year.
Important 2026 provisions
2026 Tax Law Changes That Can Affect Your Estimate
Besides regular brackets and the standard deduction, certain eligible taxpayers can claim special deductions that may affect 2026 tax liability. These deductions generally have detailed qualification and income-phaseout rules.
Qualified tips
Eligible workers may deduct up to $25,000 of qualified tips, with modified AGI phaseouts and occupation/reporting rules. Not all tips or gratuities qualify.
Qualified overtime
Eligible workers may deduct up to $12,500 of qualified overtime compensation, or $25,000 for joint filers. The qualifying overtime premium is not necessarily the entire overtime payment.
Qualified car loan interest
A deduction of up to $10,000 may apply to qualifying passenger-vehicle loan interest. Vehicle eligibility, loan conditions, purchase timing and income limits matter.
Enhanced senior deduction
Eligible individuals age 65 or older may claim up to an additional $6,000 per eligible person, subject to phaseouts beginning above specified modified AGI thresholds. This is separate from the ordinary additional standard deduction for age or blindness.
What about self-employment and investment income?
Self-employed taxpayers may need to calculate self-employment tax, the deduction for one-half of self-employment tax, and any qualified business income deduction. Qualified dividends and long-term capital gains can also receive different federal tax rates. These items require specialized calculations not included in this regular ordinary-income estimator.

Why Your Real Federal Tax May Differ from This Calculator
| Situation | Likely explanation | Action |
|---|---|---|
| Estimate is higher than tax software | Software may calculate tax credits, capital gains rates, QBI deductions or additional adjustments. | Compare taxable income, credits and applicable schedules. |
| Refund appears too large | Withholding entered may include state tax or payments from the wrong year. | Use federal withholding only and confirm all payments relate to 2026. |
| Paycheck tax differs | Paycheck withholding uses payroll periods, W-4 details and employer calculations. | Use the IRS Tax Withholding Estimator for paycheck-specific guidance. |
| Self-employment result seems too low | Self-employment tax and related deductions are not modeled automatically. | Review Schedule SE and qualifying business deductions. |
| Income includes stock sales | Some gains receive preferential capital-gains tax treatment. | Use the applicable capital gains worksheet or filing software. |
| Older taxpayer’s deduction differs | Additional standard deduction and enhanced senior deduction have separate rules. | Confirm eligibility, filing status and any senior deduction phaseout. |
When not to rely on this simplified estimate
Use detailed tax preparation calculations if your return includes alternative minimum tax, net investment income tax, foreign income rules, self-employment tax, qualified dividends, capital gains, special dependent rules, credits with refundable portions, complex business income, married-filing-separately deduction limitations or other specialized taxes.
For married filing separately when a spouse itemizes, this calculator does not automatically enforce the corresponding standard-deduction restriction. Taxpayers who can be claimed as dependents may also have a reduced standard deduction. Confirm these situations before using the result.
Frequently asked questions
10 Federal Income Tax Calculator 2026 FAQs
1. How do I calculate federal income tax for 2026?
Estimate adjusted gross income, subtract eligible deductions, calculate regular income tax using your filing status and the 2026 progressive tax brackets, and subtract eligible nonrefundable credits. Compare the result with withholding and estimated tax payments to project a balance or refund.
2. What is the standard deduction for 2026?
The basic 2026 standard deduction is $16,100 for single or married filing separately, $32,200 for married filing jointly and $24,150 for head of household. Additional amounts may apply for age 65 or blindness, subject to eligibility rules.
3. What are the seven federal income tax rates in 2026?
The seven regular federal income tax rates are 10%, 12%, 22%, 24%, 32%, 35% and 37%. The thresholds depend on filing status, and only the portion of taxable income falling into a bracket is taxed at that bracket’s rate.
4. Is federal income tax calculated on gross income or taxable income?
Regular federal income tax is generally calculated on taxable income after applicable adjustments and deductions. Gross income and adjusted gross income are earlier stages in the tax calculation.
5. Does being in the 22% tax bracket mean I pay 22% on everything?
No. The federal tax system is progressive. Lower portions of taxable income are taxed in the 10% and 12% brackets before the 22% rate applies to the next portion.
6. Does this federal income tax calculator include Social Security and Medicare?
No. This calculator estimates regular federal income tax. Social Security and Medicare payroll taxes are separate, and self-employment tax is not calculated automatically.
7. Can I estimate my 2026 federal tax refund?
Yes, for a simplified projection. Enter expected full-year federal withholding and estimated tax payments. The tool compares them with the estimated regular federal income tax after entered nonrefundable credits. Refundable credits and special taxes can change the actual refund or amount owed.
8. Does this calculator include the 2026 Child Tax Credit?
You may enter an independently calculated eligible nonrefundable Child Tax Credit amount. The tool does not automatically determine child eligibility, income phaseouts or any refundable Additional Child Tax Credit.
9. How do tips, overtime and senior deductions affect 2026 taxes?
Certain eligible taxpayers may claim special deductions for qualified tips, qualified overtime, qualifying car loan interest or age 65 or older. These deductions have eligibility conditions and income phaseouts. Determine the allowable amount using IRS guidance before entering it as an additional deduction.
10. When will I file my 2026 federal income tax return?
Most individual taxpayers will file their 2026 federal income tax return during the 2027 filing season. Confirm the applicable IRS filing deadline, including weekends, holidays and any official extensions or disaster relief.
