Estimate your federal and state income tax, FICA, and take-home pay (single filer, example brackets).
2025 federal tax brackets, single filer (example)
An income tax calculator gives you a quick estimate of how much federal income tax, state income tax, and FICA (Social Security and Medicare) you'll pay on your salary — and what's left as take-home pay. It's a simple way to get a ballpark figure for budgeting or comparing job offers, without filling out a full tax return.
This calculator uses example 2025 federal tax brackets for a single filer, applied to your taxable income (gross income minus pre-tax deductions and a standard deduction of $15,000). Federal tax brackets are progressive — each portion of your income is taxed at the rate for that bracket, not your entire income at one flat rate.
FICA: Social Security is calculated at 6.2% of gross income, and Medicare at 1.45% of gross income (these are example rates reflecting commonly used payroll tax rates).
Example: For a $75,000 gross income with no pre-tax deductions and a 5% example state tax rate, taxable income after the standard deduction is $60,000. Federal tax is calculated progressively across the brackets, FICA comes to roughly $5,738 (6.2% + 1.45% of $75,000), and state tax is roughly $3,750 — leaving an estimated take-home pay. (Note: all figures in this example are for illustration purposes only and are based on a single-filer example and do not represent your actual tax situation.)
The US uses a progressive federal income tax system with brackets that apply to a single filer's taxable income in this calculator (married filing jointly, head of household, and other filing statuses have different brackets and standard deductions). On top of federal tax, most states charge their own income tax — rates range from 0% in several states to over 10% in others — while Social Security and Medicare (FICA) are withheld from nearly every paycheck regardless of state. The federal tax year runs January through December, with returns typically due by April 15.
It uses example 2025 federal tax brackets for a single filer. Your actual bracket depends on your filing status (single, married filing jointly, etc.), which can have different bracket thresholds and standard deductions.
FICA stands for the Federal Insurance Contributions Act, which funds Social Security (6.2% of wages) and Medicare (1.45% of wages). These are withheld from almost every paycheck in addition to federal and state income tax.
State income tax rates vary enormously — some states have no income tax at all, while others have rates above 10%, often with their own brackets. Enter your actual state's rate for a more accurate estimate.
Pre-tax deductions are amounts taken from your paycheck before income tax is calculated, such as traditional 401(k) or 403(b) contributions and many employer health insurance premiums. They reduce your taxable income.
