Iowa Paycheck Calculator: Calculate Your Take-Home Pay
Use this free Iowa paycheck calculator to estimate your net pay for 2026. Enter your gross salary, filing status, and deductions to see how federal taxes, Iowa’s 3.8% flat income tax, and FICA withholdings affect every paycheck. The tool applies current rates from the IRS and the Iowa Department of Revenue so you can plan your budget with confidence.
Quick version: Iowa has a flat 3.8% state income tax on all taxable income. Combined with 2026 federal brackets and FICA, a single filer earning $75,000 keeps about $59,354 per year, or roughly $2,283 per bi-weekly paycheck. Iowa conforms to the federal standard deduction ($16,100 single, $32,200 joint) and does not tax Social Security benefits. There are no local income taxes, though some school districts levy a surtax of up to 20% of your state tax liability. Enter your salary above to see your exact take-home pay.

How to Use the Iowa Paycheck Calculator
Start by entering your gross pay amount and selecting your pay frequency. The calculator supports weekly, bi-weekly, semi-monthly, and monthly schedules. Next, choose your federal filing status and indicate whether you contribute to pre-tax benefits such as a 401(k) plan or health insurance. The calculator automatically applies the 2026 federal tax brackets enacted under the One Big Beautiful Bill Act (OBBBA), Iowa’s flat state income tax, and FICA payroll taxes to produce your estimated net pay per period.
If you file a 2024 or later IA W-4, the Iowa withholding formula uses deduction amounts of $13,000 per year for single filers, $19,500 for head of household, and $26,000 for married filing jointly when only one spouse earns income. These amounts come directly from the Iowa Department of Revenue’s updated withholding tables for 2026 and are separate from the federal standard deduction used at filing time.
Understanding Your Iowa Paycheck in 2026
Every Iowa paycheck reflects four layers of withholding: federal income tax, Iowa state income tax, Social Security tax, and Medicare tax. An employee earning $75,000 per year with single filing status and no pre-tax deductions can expect the following approximate annual breakdown.
Federal taxable income after the $16,100 standard deduction is $58,900. Federal income tax on that amount is roughly $7,670, calculated across the 10%, 12%, and 22% brackets. Iowa state tax at the flat rate of 3.8% adds about $2,238. Social Security tax of 6.2% on the full $75,000 is $4,650, and Medicare tax of 1.45% totals $1,088. Combined annual withholdings come to roughly $15,646, leaving an estimated net pay of $59,354 per year or about $2,283 per bi-weekly paycheck. The effective total tax rate in this scenario is approximately 20.9%.
Contributing to a pre-tax 401(k) changes the picture significantly. A 6% contribution on a $75,000 salary directs $4,500 into retirement savings and lowers federal and Iowa taxable income. At the 22% federal marginal rate, that saves about $990 in federal tax and $171 in Iowa tax each year. The actual reduction to your paycheck is roughly $128 per bi-weekly period rather than the full $173 contribution, making it one of the most efficient ways to build long-term wealth while reducing your current tax bill.
Iowa Income Tax Rate for 2026
Iowa applies a single flat income tax rate of 3.8% to all levels of taxable individual income. This rate took effect on January 1, 2025, following the enactment of Senate File 2442 in May 2024, which eliminated the previous multi-bracket structure. Before this change, Iowa’s top marginal rate was 5.70% in 2024, 6.00% in 2023, and as high as 8.53% in 2022. The flat rate represents a substantial simplification for Iowa taxpayers and employers alike.
Beginning with tax year 2025, Iowa conforms to the federal standard deduction rather than maintaining its own separate state deduction. For tax year 2026 under the OBBBA, this means the standard deduction available to Iowa filers is $16,100 for single filers, $32,200 for married couples filing jointly, and $24,150 for heads of household. Iowa’s median household income was $75,501 according to the most recent U.S. Census Bureau data (2024 ACS), placing many Iowa families squarely within the 22% federal bracket while paying the flat 3.8% state rate. Iowa does not tax Social Security benefits, which is a meaningful advantage for retirees.
2026 Federal Income Tax Brackets
Federal income tax uses a progressive structure with seven marginal rates. Under the OBBBA, the 2026 brackets for single filers are: 10% on taxable income up to $12,400, 12% from $12,401 to $50,400, 22% from $50,401 to $105,700, 24% from $105,701 to $201,775, 32% from $201,776 to $256,225, 35% from $256,226 to $640,600, and 37% on income above $640,600.
For married couples filing jointly, the thresholds are roughly double. These thresholds were set by IRS Revenue Procedure 2025-32 and reflect a roughly 2.8% inflation adjustment plus OBBBA amendments. This is where most people get confused: these are marginal rates, not flat rates. A single filer earning $75,000 does not pay 22% on everything. After the $16,100 standard deduction, taxable income is $58,900. The first $12,400 is taxed at 10%, the next $38,000 at 12%, and only the remaining $8,500 at 22%. The effective federal rate on that salary is roughly 10.2%, well below the 22% marginal bracket.
| Tax Rate | Single Filer | Married Filing Jointly |
|---|---|---|
| 10% | Up to $12,400 | Up to $24,800 |
| 12% | $12,401 – $50,400 | $24,801 – $100,800 |
| 22% | $50,401 – $105,700 | $100,801 – $211,400 |
| 24% | $105,701 – $201,775 | $211,401 – $403,550 |
| 32% | $201,776 – $256,225 | $403,551 – $512,450 |
| 35% | $256,226 – $640,600 | $512,451 – $768,700 |
| 37% | Over $640,600 | Over $768,700 |
FICA Taxes: Social Security and Medicare in 2026
FICA stands for the Federal Insurance Contributions Act and includes two payroll taxes that fund Social Security and Medicare. For 2026, the Social Security tax rate is 6.2% on wages up to the taxable wage base of $184,500, as confirmed by the Social Security Administration. The maximum employee Social Security tax for the year is $11,439. Your employer pays a matching 6.2%, bringing the combined rate to 12.4%.
Medicare tax is 1.45% on all wages with no cap. An Additional Medicare Tax of 0.9% applies to wages exceeding $200,000 for single filers ($250,000 for married filing jointly, $125,000 for married filing separately). Unlike the base Medicare rate, the additional 0.9% is paid only by the employee; the employer does not match it. Self-employed individuals pay both halves of FICA through self-employment tax, totaling 15.3% on net earnings up to the Social Security wage base plus 2.9% Medicare on all net earnings above it.
Iowa School District Surtax and Local Taxes
Beyond the flat 3.8% state rate, some Iowa residents owe a school district income surtax. This surtax is calculated as a percentage of your Iowa state tax liability and funds local educational improvement programs. Rates vary by school district and can reach a maximum of 20% of your state tax. For example, if your Iowa tax liability is $2,000 and your school district’s surtax rate is 10%, you would owe an additional $200. Not all school districts impose the surtax, and the applicable district is the one in which you reside on the last day of the tax year.
Six Iowa counties also levy a 1% Emergency Medical Services (EMS) income surtax: Appanoose, Cass, Pocahontas, Sac, Shelby, and Winnebago. This amount is included in the surtax table published by the Iowa Department of Revenue’s annual surtax schedule. You can find your school district name and surtax rate using your voter registration card or the Iowa tax-mapper tool at tax-mapper.iowa.gov. Because surtax rates change annually, these amounts are not included in the paycheck calculator above and should be factored in separately when you file your Iowa return.
Frequently Asked Questions
What is Iowa’s income tax rate for 2026?
Iowa has a flat income tax rate of 3.8% that applies to all levels of taxable income. This rate became effective January 1, 2025, under Senate File 2442.
Does Iowa tax Social Security benefits?
No. Iowa conforms to the federal Internal Revenue Code, and Social Security benefits that are exempt at the federal level are also exempt in Iowa.
What is the standard deduction for Iowa in 2026?
Beginning with tax year 2025, Iowa uses the federal standard deduction. For 2026, that amount is $16,100 for single filers, $32,200 for married filing jointly, and $24,150 for heads of household under the One Big Beautiful Bill Act.
How does the Iowa-Illinois reciprocity agreement work?
Iowa and Illinois have a reciprocal income tax agreement, which is Iowa’s only such arrangement. If you are an Iowa resident working in Illinois, your wages are taxed only by Iowa. You must file Form IL-W-5-NR (Employee’s Statement of Nonresidence in Illinois) with your Illinois employer to avoid Illinois withholding.
What is the Social Security wage base for 2026?
The Social Security taxable wage base for 2026 is $184,500. Earnings above this threshold are not subject to the 6.2% Social Security tax, though Medicare tax continues to apply on all wages.
How does a 401(k) contribution affect my Iowa paycheck?
Pre-tax 401(k) contributions reduce both your federal and Iowa taxable income. A $173 bi-weekly contribution (6% of a $75,000 salary) only reduces your take-home pay by about $128 after tax savings, because you avoid paying the 22% federal rate and the 3.8% Iowa rate on the contributed amount.
Are there local income taxes in Iowa besides the state tax?
Iowa has no city or county income taxes in the traditional sense, but school districts may levy a surtax of up to 20% of your state tax liability and six counties impose a 1% EMS surtax. Check the Iowa Department of Revenue surtax table to see if your district or county applies.
What is the IA W-4 form?
The IA W-4 is the Iowa Employee’s Withholding Certificate. Your employer uses it to determine how much Iowa income tax to withhold from each paycheck. The form was updated for 2026 to reflect changes under the OBBBA. You can download it from the Iowa Department of Revenue website.
