Introduction
The Iowa Paycheck Calculator shows how much money you actually take home after taxes. You enter your pay, your pay schedule, and your W-4 details. It returns your net pay per paycheck, week, month, and year.
Iowa now uses a flat state income tax rate of 3.80%. Your paycheck can also lose money to federal income tax, Social Security, Medicare, a school district surtax, and a 1% local tax if you live in Appanoose County. All of it is added into one total here.
You can also add pre-tax items like health insurance, a 401(k), an HSA, or an FSA. Post-tax items, like a Roth 401(k), can be added too. Each one changes your take-home pay, and you can see the effect right away.
Use it if you are paid hourly or by salary. Try the quick-fill buttons for common Iowa jobs, such as a nurse, teacher, warehouse worker, or software developer. The "what if" section shows what a raise or extra hours would really put in your pocket after taxes.
You also get a full breakdown of every deduction, a chart of where your money goes, and step-by-step math so you can check the numbers yourself.

Iowa Paycheck Basics: Gross Pay vs. Take-Home Pay
Your gross pay is the money you earn before anything is taken out. Your take-home pay (also called net pay) is what actually lands in your bank account. In Iowa, the gap between the two comes from four things: federal income tax, Iowa state income tax, FICA taxes, and your own payroll deductions like health insurance and retirement savings.
Iowa State Income Tax
Iowa used to have several tax brackets. Starting with tax year 2025, Iowa switched to one flat rate of 3.80% on taxable income. That means everyone pays the same rate, no matter how much they earn. Before that change, rates ran from 4.40% up to 6.00%, depending on the year and your income.
Iowa also lets you claim withholding allowances. Each allowance is a $40 credit against your Iowa tax for the year, which lowers how much is pulled from each check.
School District Surtax
Many Iowa school districts add a surtax. This is charged as a percent of the Iowa income tax you owe, not a percent of your wages. Rates are often between 0% and about 5%. So if you owe $1,000 in Iowa tax and your district charges 4%, the surtax is $40.
Local Income Tax in Iowa
Almost no Iowa county has a local income tax. Appanoose County is the exception, with a 1% local surtax on your Iowa income tax. If you live and work anywhere else in Iowa, you pay no county income tax.
Federal Taxes and FICA
Federal income tax is based on your W-4 form. The 2020 and later W-4 uses filing status, dependents, other income, and deductions instead of allowances. Older pre-2020 W-4 forms still use allowances worth $4,300 each.
- Social Security: 6.2% of wages, up to a yearly wage cap ($184,500 in 2026).
- Medicare: 1.45% of all wages, plus an extra 0.9% on wages over $200,000.
Iowa has no employee-paid disability, paid family leave, or unemployment tax. Unemployment insurance and workers' compensation are paid by your employer, not taken from your check.
Pre-Tax vs. Post-Tax Deductions
The order of deductions matters a lot. Pre-tax items come out before taxes are figured, so they lower your tax bill. Health, dental, vision, HSA, FSA, and commuter plans lower both income tax and FICA. A traditional 401(k) lowers income tax but not FICA. Post-tax items (a Roth 401(k), union dues, or wage garnishments) come out after taxes, so they shrink your check without saving you any tax.
Pay Frequency
How often you get paid changes the size of each check, not your yearly pay. Weekly means 52 checks, bi-weekly means 26, semi-monthly means 24, and monthly means 12. A bi-weekly and a semi-monthly check are not the same size, even at the same salary.
Other Iowa Pay Facts
- Iowa's minimum wage is $7.25 per hour, the same as the federal floor.
- Overtime must be paid at 1.5 times your normal rate after 40 hours in a week.
- Iowa's maximum weekly unemployment benefit runs about $736 to $901, based on family size.
Your real paycheck may differ by a few dollars. Employers use rounding rules, year-to-date wage tracking, and benefit plan rules that can shift the final numbers slightly. Always check your pay stub against your own math.
