Why Use an Income Tax Calculator?

How Federal Income Tax Is Calculated
The U.S. uses a progressive tax system: higher income is taxed at higher rates. Your taxable income is your gross income minus the standard deduction (or itemized deductions) and any above-the-line adjustments. For 2026, the standard deduction is $14,600 for single filers and $29,200 for married couples filing jointly.

Effective vs Marginal Tax Rate
Your marginal rate is the tax on your last dollar of income; your effective rate is total tax divided by gross income. A $70,000 earner might have a 22% marginal rate but only a 10–11% effective rate because of the progressive structure. The effective rate is what matters for budgeting—it tells you the real percentage of your income going to federal tax.
State Income Tax: What to Expect
Nine states have no state income tax: Alaska, Florida, Nevada, New Hampshire (dividends/interest only), South Dakota, Tennessee, Texas, Washington, and Wyoming. The rest levy state tax on top of federal tax, with rates ranging from under 3% to over 13% in California and Hawaii.
High-Tax vs No-Tax States
If you're comparing job offers across states, state tax can make a big difference. A $100,000 salary in Texas (no state income tax) leaves more in your pocket than the same salary in California (up to 9.3% state tax) or New York (up to 6.85%). Our take-home pay calculator lets you compare federal and state tax by state.
Common Questions About Income Tax
People often wonder how bonuses, overtime, or side income are taxed. Bonuses can be withheld at a flat 22% (or 37% above $1 million), but they're ultimately taxed at your marginal rate when you file. Overtime and side gig income are taxed as ordinary income. If you have multiple income sources, add them together and use our calculator with your total expected annual income.
