Iowa SUTA Tax Calculator
Figure basis: Official Iowa Workforce DevelopmentState Unemployment Tax Act (SUTA) tax is the state unemployment insurance tax that employers pay to fund unemployment benefits in Iowa. This calculator estimates your Iowa SUTA liability for the 2026 tax year. Enter the average annual wages per employee, your number of employees, and your assigned SUTA rate to see the taxable wages, tax per employee, and total tax. SUTA is charged only on the first $20,400 of each employee's wages (the 2026 Iowa taxable wage base); wages above that per employee are not taxed. Your rate is set by the state based on your business's unemployment claim history (your "experience rating"); a new employer pays 1%. SUTA is separate from the federal FUTA tax and, in most states, is paid entirely by the employer and never deducted from employee wages. All wage-base and rate figures are sourced from Iowa Workforce Development and verified for 2026. Replace the default rate with the rate on your state tax-rate notice for an exact figure.
In Iowa, employers pay SUTA on the first $20,400 of each employee's wages for 2026, and a new employer pays 1%. For 5 employees earning $50,000 each at 1%, the estimated annual SUTA tax is $1,020.00 ($204.00 per employee).
How Iowa SUTA tax works
Iowa charges state unemployment tax on each employee's wages up to the taxable wage base of $20,400 for 2026. Once an employee has earned that much in the year, no further SUTA is due on that employee. Your rate is assigned by the state from your experience rating; a new employer pays 1%.
taxable wages per employee = min(annual wages, $20,400)
SUTA tax per employee = taxable wages per employee x rate / 100
total SUTA tax = SUTA tax per employee x number of employees
Worked example: 5 employees each earning $50,000 in Iowa at 1%. Each employee's taxable wages are capped at $20,400, so the tax per employee is $204.00 and the total is $1,020.00.
Iowa SUTA figures (2026)
| Figure | Value | Source |

| Taxable wage base | $20,400 | Iowa Workforce Development |
| New employer rate | 1% | Iowa Workforce Development |
| Experience rate range | 0% to 5.4% | Iowa Workforce Development |
The experience-rate range shown is the base statutory range. Most states add mandatory assessments on top (for example a fund-building, solvency, or administrative surcharge), so an employer's effective rate can be higher than the range shown, and the new-employer rate may exclude those add-ons. Your exact assigned rate is on your annual state tax-rate notice.
Why Iowa's wage base sits higher than its neighbors
Iowa is the outlier in this group. Its 2026 taxable wage base is $20,400, more than double Indiana's or Maryland's, because Iowa indexes the base to a share of the statewide average wage rather than freezing it at a round number. A higher base means SUTA follows more of each worker's pay before it stops, so the per-employee math is larger even when the rate looks small.
That is where Iowa balances the scale: the new employer rate is just 1%. On the $20,400 base, 1% caps a new employer's cost at $204.00 per employee per year, among the gentler entry points nationally. Iowa Workforce Development sets rates from a numbered table (Iowa uses one of the lower table positions for 2026), and experience-rated employers span roughly 0% to 5.4%. A strong account can genuinely reach the 0% floor and pay nothing, while the top of the schedule reaches about $1,101.60 per employee.
For a new Iowa employer, the takeaway is to plan for a modest first-year rate but a wide base: budget on the full $20,400 per worker, not a smaller cap. Once you receive your annual rate notice, enter that exact rank-based rate in the calculator above. Because the base is indexed, expect it to move each year, so re-check the figure every January rather than assuming last year's number still holds.
Iowa SUTA tax: frequently asked questions
What is the Iowa unemployment (SUTA) taxable wage base for 2026?
For 2026, Iowa employers pay state unemployment tax on the first $20,400 of each employee's wages. Wages above $20,400 per employee are not subject to SUTA.
What is the Iowa new employer SUTA rate?
New employers in Iowa pay a SUTA rate of 1% until they have enough history to be experience-rated. On the $20,400 wage base that is up to $204.00 per employee per year.
How is Iowa SUTA tax calculated?
Multiply each employee's wages, capped at the $20,400 taxable wage base, by your assigned experience rate, then add up across employees. SUTA is primarily an employer-paid tax and is not deducted from employee pay.
Is the Iowa SUTA rate the same for every employer?
No. After the new-employer period, Iowa assigns each employer an experience rate based on its history of layoffs and claims, generally ranging from about 0% to 5.4% for experience-rated employers before any state add-on surcharges. The rate field above defaults to the new-employer rate; replace it with the rate on your state tax notice for an exact figure.
