How this estimate works
Federal tax uses the 2026 IRS brackets and the $16,100 single standard deduction; FICA is 6.2% Social Security up to the $184,500 wage base plus 1.45% Medicare; Iowa tax uses the 2026 state brackets, deduction, and exemption figures shown above. The estimate excludes local income taxes, state disability or paid-leave payroll taxes, and credit phaseouts, so an actual Iowa pay stub can differ. Every assumption is listed on our methodology page, and sources cites each 2026 figure.
