    "shortDescription": "Take-home pay after taxes",
    "longDescription": "Estimate your take-home pay per paycheck and per year in any US state, with 2026 federal withholding, Social Security, Medicare, state income tax and state payroll taxes.\n\nEnter a salary or an hourly rate, how often you are paid, your filing status and state. Add 401(k), HSA and pre-tax health premiums, children and other dependents from your W-4, extra withholding or the two-jobs box. Federal tax follows the IRS 2026 percentage method (Publication 15-T, updated for the One Big Beautiful Bill Act). Social Security is 6.2% up to the 2026 wage base of $184,500 and Medicare is 1.45% plus 0.9% over $200,000. State income tax covers all 50 states and DC, with each state's source and year, and notable payroll taxes such as California SDI, New York disability and paid family leave, New Jersey TDI and FLI, Washington paid leave and WA Cares. New York City and Yonkers residents can include the city tax.\n\nThe card shows take-home per paycheck, a chart of where the money goes and a per-paycheck and yearly breakdown; slide the salary or 401(k), or switch state and pay frequency. A second tool converts pay between hourly, weekly, biweekly, monthly and yearly. Estimates, not tax advice. Nothing is stored.",
