Electronic Income Withholding (e-IWO) Information


Electronic Income Withholding (e-IWO) is a federal program where employers can receive income withholding notices (original, amended or terminated) electronically. The details of the program can be found at http://www.acf.hhs.gov/programs/css/employers/e-iwo.

If you are already signed up for e-IWO you will automatically receive electronic notices from Wisconsin. Wisconsin will start sending electronic income withholding as of September 23, 2015.

Employers can respond to an income withholding request or report employee terminations through e-IWO. This is a great way to reduce paper processing time and mail expenses.

If you are not signed up, see the Office of Child Support Enforcement website to do so.
