The U.S. federal income tax system is progressive: the top 1% of earners pay 45.8% of all federal income taxes, while the bottom 50% pay just 2.3% (IRS SOI, 2024). Despite a top marginal rate of 37%, the average effective rate across all filers is only 14.9% due to deductions, credits, and the progressive bracket structure. Use the calculator above to see exactly where your income falls and how much you owe. For state-level income tax, try our state income tax calculator.

How Federal Income Tax Works (2026 Tax Year)
The United States uses a progressive tax system, meaning your income is divided into portions called brackets, and each portion is taxed at a progressively higher rate. A common misconception is that moving into a higher bracket means all your income is taxed at that rate. In reality, only the income within each bracket is taxed at that bracket's rate.
For the 2026 tax year, there are seven federal income tax brackets: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. The income ranges for each bracket depend on your filing status — single, married filing jointly, married filing separately, or head of household. Use our tax bracket calculator to see exactly which bracket your last dollar falls into.
Standard Deduction vs. Itemized Deductions
Before calculating your tax, you reduce your gross income by either the standard deduction or your itemized deductions — whichever is larger. For 2026, the standard deduction is $15,000 for single filers, $30,000 for married filing jointly, and $22,500 for head of household. Most taxpayers take the standard deduction because it exceeds their total itemizable expenses.
Common itemized deductions include mortgage interest, state and local taxes (SALT, capped at $10,000), charitable contributions, and medical expenses exceeding 7.5% of adjusted gross income. If your itemized deductions total more than the standard deduction, itemizing saves you more money. Homeowners in high-tax states often benefit from itemizing, especially if they have significant property tax and state income tax payments.
Understanding FICA Taxes
In addition to federal income tax, most workers pay FICA taxes — Social Security (6.2%) and Medicare (1.45%). Social Security tax applies to the first $176,100 of earnings in 2026. Medicare has no wage cap, and an additional 0.9% Medicare surtax applies to earnings above $200,000 for single filers ($250,000 for married filing jointly).
Self-employed individuals pay both the employee and employer portions of FICA, totaling 15.3%. Use our self-employment tax calculator to estimate your SE tax liability. If you are a W-2 employee, your employer pays the other half of FICA, so you only see the employee portion deducted from your paycheck.
Effective Tax Rate vs. Marginal Tax Rate
Your marginal tax rate is the rate applied to your next dollar of income — it corresponds to the highest bracket your income falls into. Your effective tax rate is the actual percentage of your total income that goes to taxes. Because of the progressive system, your effective rate is always lower than your marginal rate.
For example, a single filer earning $80,000 has a marginal rate of 22% but an effective federal income tax rate of approximately 13.5%. This distinction matters when evaluating raises, bonuses, or side income — you are never "penalized" for earning more because only the additional income is taxed at the higher marginal rate. See our effective tax rate calculator for a detailed breakdown.
2026 Federal Tax Brackets at a Glance
| Rate | Single | Married Filing Jointly | Head of Household |
|---|---|---|---|
| 10% | $0 - $11,925 | $0 - $23,850 | $0 - $17,000 |
| 12% | $11,925 - $48,475 | $23,850 - $96,950 | $17,000 - $64,850 |
| 22% | $48,475 - $103,350 | $96,950 - $206,700 | $64,850 - $103,350 |
| 24% | $103,350 - $197,300 | $206,700 - $394,600 | $103,350 - $197,300 |
| 32% | $197,300 - $250,525 | $394,600 - $501,050 | $197,300 - $250,500 |
| 35% | $250,525 - $626,350 | $501,050 - $751,600 | $250,500 - $626,350 |
| 37% | Over $626,350 | Over $751,600 | Over $626,350 |
Worked Example: Single Filer Earning $85,000
Let us walk through the federal income tax calculation for a single filer with $85,000 in gross income using the standard deduction:
| Step | Amount |
|---|---|
| Gross Income | $85,000 |
| Standard Deduction | -$15,000 |
| Taxable Income | $70,000 |
| 10% on first $11,925 | $1,193 |
| 12% on $11,925 - $48,475 | $4,386 |
| 22% on $48,475 - $70,000 | $4,736 |
| Total Federal Tax | $10,314 |
| Effective Rate | 12.1% |
| Marginal Rate | 22% |
| Social Security (6.2%) | $5,270 |
| Medicare (1.45%) | $1,233 |
| Total Tax (Federal + FICA) | $16,816 |
| Annual Take-Home | $68,184 |
Notice that even though this filer is in the 22% bracket, their effective federal income tax rate is only 12.1%. The progressive structure ensures that lower portions of income are taxed at lower rates. State income tax (if applicable) would further reduce take-home pay.
Tips to Reduce Your Tax Liability
- Maximize retirement contributions: Contributing to a traditional 401(k) or IRA reduces taxable income dollar-for-dollar. The 2026 401(k) limit is $23,500 ($31,000 if age 50+).
- Use an HSA: Health Savings Accounts offer triple tax benefits — tax-deductible contributions, tax-free growth, and tax-free withdrawals for medical expenses.
- Claim all eligible credits: Tax credits like the Child Tax Credit ($2,000 per child), Earned Income Tax Credit, and education credits directly reduce your tax bill.
- Time your income: If you expect to be in a lower bracket next year, consider deferring bonus income or freelance payments to the following year.
- Harvest capital losses: Selling investments at a loss can offset capital gains and up to $3,000 of ordinary income per year.
States With No Income Tax
Nine states have no state income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. New Hampshire and Washington tax only investment income and capital gains, respectively. Living in one of these states means your federal tax burden (calculated above) is essentially your entire income tax obligation.
However, states without income tax often compensate with higher property taxes (Texas at 1.68%) or sales taxes (Tennessee at 9.55%). When comparing states, consider the total tax burden across all categories, not just income tax alone.
