US Income Tax Calculator (2025–2026): Estimate Federal Tax Brackets, Effective Rate & Take-Home Pay
Our US Income Tax Calculator computes your exact federal income tax liability, state income tax, FICA payroll withholdings (Social Security and Medicare), marginal tax bracket, effective tax rate, and net take-home pay for the 2025 and 2026 tax years. Using the official IRS inflation-adjusted tax brackets and the $15,000 Single / $30,000 Married Filing Jointly standard deduction, it shows exactly how each slice of your income is taxed and how 401(k), HSA, and IRA deductions cut your tax bill.
Official 2025–2026 IRS Federal Income Tax Brackets & Standard Deductions
The United States uses a progressive marginal tax system under the Internal Revenue Code. After subtracting above-the-line adjustments (401(k), HSA, Traditional IRA) and your Standard Deduction ($15,000 Single, $30,000 Married Filing Jointly, $22,500 Head of Household) from gross income, your remaining Taxable Income flows sequentially through the seven IRS brackets below:
| Marginal Tax Rate | Single Filer (Taxable Income) | Married Filing Jointly (Taxable Income) | Head of Household (Taxable Income) | Married Filing Separately |
|---|---|---|---|---|
| 10% | $0 to $11,925 | $0 to $23,850 | $0 to $17,000 | $0 to $11,925 |
| 12% | $11,926 to $48,475 | $23,851 to $96,950 | $17,001 to $64,850 | $11,926 to $48,475 |
| 22% | $48,476 to $103,350 | $96,951 to $206,700 | $64,851 to $103,350 | $48,476 to $103,350 |
| 24% | $103,351 to $197,300 | $206,701 to $394,600 | $103,351 to $197,300 | $103,351 to $197,300 |
| 32% | $197,301 to $250,525 | $394,601 to $501,050 | $197,301 to $250,500 | $197,301 to $250,525 |
| 35% | $250,526 to $626,350 | $501,051 to $751,600 | $250,501 to $626,350 | $250,526 to $375,800 |
| 37% | Over $626,350 | Over $751,600 | Over $626,350 | Over $375,800 |
Worked Tax Calculation Example: $88,000 Single Earner vs. $165,000 Married Couple
Many taxpayers mistakenly assume that being “in the 22% tax bracket” means paying 22% on every dollar earned. Let’s trace David, a Single filer in Chicago earning $88,000 in W-2 salary who takes the $15,000 standard deduction (leaving $73,000 in federal taxable income):
- 10% Bracket ($0 to $11,925):
$11,925 × 10%= $1,192.50 - 12% Bracket ($11,925 to $48,475):
$36,550 × 12%= $4,386.00 - 22% Bracket ($48,475 to $73,000):
$24,525 × 22%= $5,395.50 - Total Federal Income Tax:
$1,192.50 + $4,386.00 + $5,395.50= $10,974.00 - Marginal vs. Effective Tax Rate: While David’s marginal tax bracket is 22%, his effective federal income tax rate is only
$10,974 ÷ $88,000= 12.47%! - Adding FICA & Illinois State Tax (4.95%): Social Security (6.2% = $5,456) + Medicare (1.45% = $1,276) + Illinois state tax ($4,356) brings David’s total annual take-home pay to $65,938 ($5,495/month).

Frequently Asked Questions
Federal income tax has seven progressive brackets: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. For 2026 (IRS Rev. Proc. 2025-32), the 10% bracket applies up to $12,400 for single filers ($24,800 married filing jointly), and the top 37% bracket starts above $640,600 single ($768,700 married filing jointly). For 2025, the 10% bracket applies up to $11,925 single ($23,850 married filing jointly) and the 37% bracket starts above $626,350 single ($751,600 married filing jointly).
Under the One Big Beautiful Bill Act (P.L. 119-21) and IRS Rev. Proc. 2025-32, the 2025 standard deduction is $15,750 for single filers and married filing separately, $31,500 for married filing jointly, and $23,625 for head of household. For tax year 2026, the standard deduction rises to $16,100 (single/MFS), $32,200 (married filing jointly), and $24,150 (head of household).
Under enacted 2025 tax legislation (P.L. 119-21), the state and local tax (SALT) itemized deduction cap increased from $10,000 to $40,000 for 2025 ($20,000 for married filing separately) and $40,400 for 2026 ($20,200 MFS), subject to a phase-out for modified AGI above $500,000 ($505,000 in 2026).
Your marginal tax rate is the rate applied to your last dollar of taxable income (your highest tax bracket). Your effective tax rate is the percentage of your total gross income paid in federal tax (total federal tax divided by gross income). Because the US system is progressive and includes a standard deduction, your effective rate is always lower than your marginal bracket.
FICA taxes consist of Social Security (6.2% on wages up to $184,500 in 2026, $176,100 in 2025, and $168,600 in 2024) and Medicare (1.45% on all wages, plus a 0.9% Additional Medicare Tax on wages over $200,000 for single filers or $250,000 for married filing jointly).
