This free Iowa paycheck calculator shows your 2026 take-home pay from a salary or hourly wage. Iowa taxes wages at a flat 3.8% in 2026. As recently as 2022 the top rate was 8.53%. Iowa starts from your federal taxable income. So the federal standard deduction shelters your first dollars from state tax too.
The calculator runs on the 2026 federal brackets and the $184,500 Social Security wage base. Money you put in a 401(k) skips federal and Iowa income tax but still pays FICA. HSA money taken from your paycheck skips all three.
How Iowa taxes your paycheck in 2026
Iowa has rebuilt its income tax fast. In 2022 the top rate was 8.53% spread across nine brackets. For 2026 every dollar of taxable income pays a flat 3.8%. The Iowa Department of Revenue confirmed the 2026 rate in its October 2025 announcement.
How the tax is built matters as much as the rate. Iowa starts from your federal taxable income. That is your pay after the federal standard deduction, which is $16,100 for a single filer. So a $60,000 earner pays Iowa tax on roughly $43,900, not on $60,000. That brings the state bite to about 2.8% of gross pay. Small personal exemption credits of $40 single and $80 joint cut the bill a little more.
Retired people do even better. Iowa does not tax retirement income at all once you are 55 or older. That covers money you pull from a 401(k) or IRA, and pensions too.
What Iowa take-home pay looks like in 2026
Say you file single, earn $60,000, and put nothing away before tax. You take home about $48,762 a year in 2026. That is roughly $1,875 in each biweekly paycheck, a total tax rate of about 18.7%. At $100,000 the same filer keeps around $76,032, or $2,924 every two weeks. That is a rate near 24.0%.
That puts Iowa below its bigger neighbor. Illinois taxes the same salaries at a flat 4.95%. Illinois offsets that with only a $2,925 exemption allowance. Iowa has the lower rate and lets the federal standard deduction flow through. So an Iowa paycheck is larger at every income level. The two states also have a reciprocity deal, so commuters pay tax only where they live.
Saving before tax adds to the advantage. Iowa builds on your federal taxable income. So anything that lowers your federal taxable wages lowers your Iowa tax too. A traditional 401(k) does this, and so does an HSA taken from your paycheck. Iowa adds nothing back on the state return.
The school district surtax — the line this calculator does not show
Here is a twist you only find in Iowa. Hundreds of school districts charge an income surtax. The surtax is a percentage of your Iowa income tax, not of your income. It usually runs from 1% to 20% of that tax. Say your district charges 10% and your Iowa tax is $1,600. You then owe an extra $160 at filing time.
This calculator leaves out the school district surtax. The surtax depends on the district where you live, not where you work. Look up your district’s current rate on the Iowa Department of Revenue site. Then add that percentage of your state tax yourself. It usually changes the yearly number by a few hundred dollars.
Apart from that surtax, Iowa has no local wage taxes. Des Moines, Cedar Rapids and Davenport paychecks all carry the same deductions.

- What is the Iowa school district surtax?
- Hundreds of Iowa school districts add a surtax. It is worked out as a percentage of your Iowa income tax, not of your income. The rate usually runs from 1% to 20%.

- Does Iowa tax retirement income?
- No, not once you are 55 or older. Iowa leaves retirement income out of state tax completely. That covers money you pull from a 401(k) or an IRA. Pensions count too. You still owe federal tax on that money. Working Iowans under 55 pay the flat 3.8% on wages.
- What is FICA on my Iowa paycheck?
- FICA is the pair of federal taxes for Social Security and Medicare. Social Security takes 6.2% of your wages up to $184,500 in 2026. Medicare takes 1.45% of every dollar. Pay above $200,000 adds another 0.9%. Iowa does not touch FICA, and your employer pays a matching share.
