Iowa SUI Tax Credit: Check Your IWD Account
Iowa cut the SUI taxable wage base nearly in half for 2026. Many employers overpaid in the first quarter and now have a credit waiting on their IWD account.
June 3, 2026
A few weeks ago I got an email saying I had an important message about my payroll tax. Logging in and tracking it down took more clicks than it should have, but it was worth it. There was a credit on my account.
I filed it away as a pleasant mystery. Then my legal briefing this week explained what happened. If you have employees in Iowa, this may affect you too.
What changed
Iowa passed Senate File 607, which restructured how state unemployment insurance (SUI) taxes are calculated. Two numbers tell the story.
The wage base is the amount of each employee's earnings subject to SUI tax. Cutting it roughly in half means you stop paying unemployment tax on most of your employees' wages much earlier in the year. For a higher wage employee, that cap is hit in the first quarter.
Iowa also activated "Table D" for 2026, the lowest rate schedule allowed under state law. Depending on your unemployment claims history, your rate for 2026 falls somewhere between 0% and 5.4%. New employers start at 1.0%, except construction, which starts at the 5.4% maximum.
Why you may have a credit
When the first quarter ended and employers filed, Iowa Workforce Development reconciled what was actually owed under the new rules against what many had already remitted.
Payroll software does not always update tax tables instantly. Some businesses, especially those using larger processors like ADP, Paychex, or Gusto, may have been calculating against the old $39,500 base. Iowa Workforce Development is issuing credits rather than automatic refunds, so the money sits on your account until you use it.
What to do now
If one is there, you can apply it to your second quarter payment, due July 31, 2026, rather than leaving it to sit.
The correct figures for 2026 are a $20,400 wage base and your Table D rate. If you are not sure what your rate is, it should be on your IWD rate notice.
Because the cap is so much lower this year, many of your employees will have fully capped out by mid summer. Your SUI liability in the back half of the year may be much lower than in prior years.

A note for Texas employers
Texas has its own SUI structure administered by the Texas Workforce Commission, and your wage base and rate schedules are set separately. None of the Iowa numbers above apply to you.
Still, this is a good prompt to audit your Texas Workforce Commission account and confirm your payroll processor is using your correct 2026 rate. The Texas Employment Law Guide on our downloads page covers the basics of employer obligations, including payroll compliance.
The bottom line
Payroll tax changes rarely announce themselves. They show up as a number that is quietly wrong, in software you assumed was current, for months before anyone notices.
