Unemployment tax

Companies are liable for state unemployment when any wages are paid. Check out the New Business Fact Sheet to learn how to register. You can also check your liability and register online with the Iowa Workforce Development. You should receive your UI account number and rate instantly after registering online.

Contribution Rate

The rate ranges from 1–7.5% for new employers. If you're unsure of your rate, please call the agency at (866) 239-0843.

Troubleshoot Workforce Development authorization issues

Some agencies require special authorization for Gusto to pay or file your taxes. To do this in Iowa, Gusto will request a 17-digit ACH credit number from the department of Workforce Development on your behalf.

To ensure the success of our request, please verify that the following information you have entered into Gusto matches what is on file with the agency:

  • Official company name/address
  • FEIN - Federal Employment Identification Number
  • Unemployment Account Number 

If Gusto is having trouble gaining access to your account, please verify that the above information matches exactly what the agency has on file by giving them a call at (888) 848-7442.
