How the 2026 Federal Tax Calculator Works
This calculator estimates US federal individual income tax using your annual gross income, filing status, standard deduction, and additional deductions.
Step 1: Select Your Filing Status
Select the filing status that best matches your situation. The available options are Single, Married Filing Jointly, Married Filing Separately, and Head of Household.
Step 2: Enter Your Annual Income
Enter your estimated annual gross income before applying deductions.
Step 3: Enter Additional Deductions
If applicable, enter additional deductions that you want included in this simplified estimate.
Step 4: Calculate Taxable Income
The calculator subtracts the applicable standard deduction and additional deductions from gross income.
Taxable Income = Gross Income − Total Deductions
Step 5: Apply Federal Tax Brackets
Federal income tax is calculated progressively. Different portions of taxable income fall into different tax brackets.
This means that reaching a higher marginal tax bracket does not mean that your entire income is taxed at that higher percentage.
2026 Standard Deduction
The standard deduction reduces the amount of income subject to federal income tax. The amount depends on your filing status.
| Filing Status | 2026 Standard Deduction |
|---|---|
| Single | $16,100 |
| Married Filing Jointly | $32,200 |
| Married Filing Separately | $16,100 |
| Head of Household | $24,150 |
These standard deduction amounts are for the 2026 tax year. Taxpayers may have additional deductions, adjustments, or special rules that are not included in this simplified calculator.
2026 Federal Income Tax Brackets
The United States uses a progressive federal income tax system. The following rates are applied to different portions of taxable income.
| Tax Rate | Single | Married Filing Jointly | Married Filing Separately | Head of Household |
|---|---|---|---|---|
| 10% | $0 – $12,400 | $0 – $24,800 | $0 – $12,400 | $0 – $17,700 |
| 12% | $12,401 – $50,400 | $24,801 – $100,800 | $12,401 – $50,400 | $17,701 – $67,450 |
| 22% | $50,401 – $105,700 | $100,801 – $211,400 | $50,401 – $105,700 | $67,451 – $105,700 |
| 24% | $105,701 – $201,775 | $211,401 – $403,550 | $105,701 – $201,775 | $105,701 – $201,750 |
| 32% | $201,776 – $256,225 | $403,551 – $512,450 | $201,776 – $256,225 | $201,751 – $256,200 |
| 35% | $256,226 – $640,600 | $512,451 – $768,700 | $256,226 – $384,350 | $256,201 – $640,600 |
| 37% | Over $640,600 | Over $768,700 | Over $384,350 | Over $640,600 |
Tax brackets apply to taxable income, not directly to gross income.
Marginal Tax Rate vs. Effective Tax Rate
Marginal Tax Rate
Your marginal tax rate is the percentage applied to the next dollar of taxable income within your applicable federal tax bracket.
For example, being in the 22% federal tax bracket does not mean that all of your taxable income is taxed at 22%.
Effective Tax Rate
Your effective federal tax rate represents your estimated federal income tax as a percentage of your gross income.
Effective Tax Rate = Federal Income Tax ÷ Gross Income × 100
Because the federal income tax system is progressive, the effective tax rate is generally lower than the marginal tax rate for taxpayers with taxable income extending across multiple brackets.
What Is Taxable Income?
Taxable income is the amount of income that remains subject to federal income tax after applicable deductions and adjustments included in the calculation.
This calculator uses a simplified calculation based on gross income, the standard deduction, and the additional deductions entered by the user.
Taxable Income = Gross Income − Total Deductions
If deductions are greater than gross income, taxable income cannot be less than zero for the purposes of this calculator.
How Progressive Federal Tax Brackets Work
The US federal income tax system uses progressive tax brackets. Each bracket applies only to the portion of taxable income that falls within that bracket.
Example
Suppose a taxpayer's taxable income extends into the 22% bracket. The entire taxable income is not automatically taxed at 22%.
Instead, the calculator applies the applicable rate to each portion of taxable income that falls within the corresponding tax bracket.
Important: A higher marginal tax bracket does not mean that all of your income is taxed at that higher rate.
