How This Calculator Works

Federal income tax in the US uses a progressive bracket system — your income is divided into chunks, and each chunk is taxed at a different rate. For 2026, the brackets range from 10% on your first dollars earned up to 37% on income above $609,350 (single). The key thing to understand: only the income within each bracket gets that rate. A $75,000 earner doesn't pay 22% on everything — they pay 10% on the first $11,600, 12% on the next chunk, and 22% only on the amount above $47,150. That's why your effective rate is always lower than your marginal rate.

Before the brackets apply, you get the standard deduction: $15,000 for single filers, $30,000 for married filing jointly, or $22,500 for head of household. This comes off the top of your gross income. So a single person making $75,000 is only taxed on $60,000. Pre-tax deductions like 401(k) contributions and HSA deposits further reduce your taxable income — every dollar you contribute saves you at your marginal rate.

On top of federal income tax, there's FICA: 6.2% for Social Security (up to the $176,100 wage cap) and 1.45% for Medicare (no cap). Add 0.9% more Medicare if you earn above $200,000. That's 7.65% total for most earners, and it's calculated on your gross income before any deductions — including 401(k) contributions.

Then there's state income tax, which varies wildly. Texas and Florida: 0%. Illinois: 4.95% flat. California: 1%–13.3% progressive. New York: 4%–10.9% progressive, plus NYC residents pay an additional 3.078%–3.876% city tax. The state you live in can easily mean thousands of dollars difference on the same salary. This calculator handles all five states plus the federal calculation.

The bottom line: your income tax burden depends on three big factors — your filing status, your state of residence, and your pre-tax deductions. Use this calculator to see the full picture: federal tax, FICA, state tax, and your actual take-home pay.

Frequently Asked Questions

How do I calculate my income tax?
Your federal income tax uses progressive brackets. For 2026, the brackets range from 10% to 37%. You subtract the standard deduction ($15,000 for single, $30,000 for married) from your gross income, then apply each bracket rate to the income within that bracket. Add FICA (7.65%) and any state tax on top. This calculator does all of that automatically.
What are the 2026 federal income tax brackets?
For single filers: 10% up to $11,600, 12% up to $47,150, 22% up to $100,525, 24% up to $191,950, 32% up to $243,725, 35% up to $609,350, and 37% above that. Married filing jointly brackets are roughly double. Only income within each bracket gets that rate — your effective rate is always lower than your marginal rate.
How much income tax do I pay on $75,000?
A single filer earning $75,000 would pay roughly $8,718 in federal income tax after the $15,000 standard deduction, plus $5,738 in FICA. State tax depends on where you live — $0 in Texas/Florida, about $3,575 in Illinois, $4,050 in California, and $3,550 in New York. Total effective federal rate is around 11.6%.
What is the standard deduction for 2026?
$15,000 for single filers, $30,000 for married filing jointly, and $22,500 for head of household. This amount is subtracted from your gross income before calculating tax. Most people take the standard deduction rather than itemizing.
Do 401(k) contributions reduce income tax?
Yes. Traditional 401(k) contributions reduce your taxable income dollar-for-dollar for federal and state income tax purposes (but not FICA). Contributing $10,000 to a 401(k) on a $75,000 salary means you're only taxed on $65,000 for income tax. At the 22% bracket, that saves you $2,200 in federal tax alone.
What is the difference between gross income and taxable income?
Gross income is your total earnings before any deductions. Taxable income is what's left after subtracting the standard deduction (or itemized deductions) and pre-tax contributions like 401(k) and HSA. The IRS only taxes your taxable income, not your gross.
