US Tax & Paycheck Calculators

Work out US federal income tax, take-home pay and payroll withholding with the figures the IRS publishes for the current tax year. These calculators use the official 2026 federal tax brackets, the standard deduction and the FICA wage base, so the numbers match what lands on a real paycheck or a filed return. Estimate your take-home pay from an hourly wage or annual salary, including federal withholding, Social Security and Medicare, and see how 401(k) contributions or pre-tax deductions change the result. Compare filing statuses, work out self-employment tax and quarterly estimated payments, and check capital gains, bonus withholding and the child tax credit. Every tool shows its workings step by step and links to its IRS source, and every result carries the reminder that it is an estimate for planning only, not tax advice. Use them to plan a budget, compare job offers, or check a paycheck before tax season — free, private, and entirely in your browser.
