How Your IA Paycheck Works
Iowa paychecks start with federal income tax withholding under IRS Publication 15-T's wage-bracket or percentage method, applied using Form W-4, taxable wages, pay schedule, and filing status. FICA is calculated separately: Social Security is 6.2% on covered wages up to the 2026 wage base of $184,500, Medicare is 1.45% on all covered wages, and the 0.9% Additional Medicare Tax is withheld after an employee's wages exceed $200,000 in the calendar year. Iowa's individual income tax is a flat 3.8% rate for 2026, announced by the Iowa Department of Revenue as part of the state's ongoing income tax reform. Iowa does not have a separate statewide employee SDI or paid family leave payroll deduction beyond state income tax withholding. Estimates assume standard 2026 withholding, single filing status, and no pre-tax deductions; actual paycheck may differ.
