IDR continues to work with software vendors to register and test their software to increase the number of vendors that support Iowa. As a result, this list is a resource of software vendors and service providers who have successfully tested their product and support electronic filing of W-2s and 1099s for Iowa. This page will be updated as new vendors are added. Sign up for email updates to learn more about these services.

The Department will accept files from any and all sources able to format the data per the Department's requirements.
