An important component of the Wisconsin Child Support Program is the state statutory requirement that all orders for child support, maintenance and family support include a provision for immediate income withholding by the payer's employer. Income withholding is required whether or not the individual is delinquent in making payments.

Current obligations, past-due support, and annual receipt and disbursement fees are subject to income withholding per Wis. Stat. s. 767.75.

Timelines for Withholding Support

Employers must begin withholding support no later than the first pay period occurring five working days from the date on the income withholding notice. All support and support-related payments must be submitted to the Wisconsin Support Collections Trust Fund (WI SCTF) within five days of the withholding date.

Income withholding orders remain in effect until the employer is notified otherwise. You will receive a notice if the terms of the order change, or when the order is no longer in force. You must keep the income withholding notice on file and withhold the stated amount whenever the employee receives a paycheck. This applies to all employers.

Costs and Charges for Income Withholding

You may deduct a fee from an employee's wages to offset withholding costs. You may deduct this fee from the employee's wages, commission check, or other sources of income, but not from the support payment. The fee does not affect the employee's gross income for calculating support amounts. By law, the fee must reflect the actual cost, but may not exceed $3 per withholding.

In general, you may charge more than one fee from the same paycheck if you send in the withholdings to separate addresses or with separate documentation, such as:

  • Withholding child support and withholding R&D Fees from the same paycheck (requires separate documentation and mailing).
  • Withholding child support from the same paycheck for two child support orders if the orders are from two different states (remitted to two different locations).

You may not charge separate fees for two or more withholdings from one paycheck if the withholdings from one paycheck are all remitted to the WI SCTF with the same documentation. For example:

  • Withholding for two Wisconsin child support orders.
  • Withholding for current and past-due support.

You may not charge a fee for sending withheld premiums to an insurance provider.

Electronic Income Withholding Order (e-IWO) Information

Electronic Income Withholding Order (e-IWO) is a federal program where employers can receive income withholding order notices (original, amended or terminated) electronically. Learn more about the program.

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

Employers can respond to an income withholding order 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 Services website to do so.

Submitting Withholdings by Mail

You may submit the withheld support by mail. You should receive a pre-printed Employer Withholding List or Coupon for employees with a Wisconsin support order. Coupons are sent to employers with a limited number of employees with support orders and lists are sent to employers who have several employees with support orders. For support withheld for a Wisconsin order, mail your check (payable to WI SCTF) along with your list or coupon to:

      WI SCTF 
      Box 74400 
      Milwaukee, WI 53274-0400

The templates below can be used in lieu of the pre-printed withholding list or coupon. These templates include all required fields.

The items listed below are critical to ensure support payments are distributed correctly, especially if your employee has more than one court order.

Information about your company:

  • Company Name
  • Your Company's KIDS Employer ID (listed in item 10, on page 2 of the withholding notice)

Information about the employee:

  • Withholding date - the date you withheld the support obligation amount from the employee's wages
  • Employee's name - first name, middle initial, and last name
  • Employee's case identification PIN or Social Security Number/Individual Tax ID Number

Modifying a Withholding Coupon or List

Complete and return the changed list or coupon with your payment. Please make sure the amount of the check equals the amount noted on your withholding list/coupon. Note any changes that should be made:

  • If you no longer want to receive the list, mark "x" in the "Discontinue Lists" box.
  • If your business address is incorrect, mark "x" in the "Address Change" box. Write your correct address on the face of the withholding list/coupon.
  • To add a new employee, or an employee with a new income withholding order:
    • If you currently receive the Employer Withholding List/Coupon for one employee, you may download a coupon for the additional employee, or you may create your own list/coupon for an additional employee. This list/coupon must contain the same required information as the Employer Withholding List/Coupon. The following month you will receive a list/coupon that includes both employees' names.
    • If you currently receive the Employer Withholding List/Coupon for more than one employee, add the new employee's name and the related data to the "Added Employee Table" in the section labeled "Withholding List Changes Coupon." You must also add all the required information for the added employee. Your next month's withholding list/coupon will have the added employee's name.
  • To remove an employee name, mark "x" in the "No Longer Employed" box. If known, please write the termination date directly below the employee's name. Do not remove the name if the employee is temporarily laid off, receiving worker's compensation/disability, or is a season worker and will return next season.

Questions Parents ask about Income Withholding

Why can't I just write the checks myself?

Wisconsin law requires income withholding. Generally, only self-employed parents do not use income withholding. Those who are self-employed might need to arrange for automatic payments of support from a bank account.

My employer is not happy about the income withholding because it creates more paperwork. I am worried about losing my job.

Under the law, your employer may not fire you because of income withholding. If you can show that income withholding causes you irreparable harm, you may ask the court for another payment option. Your request to the court must be made within 10 days of the income withholding notice being mailed to you.

What happens if there is a mistake in income withholding? What if the employer takes too much money or doesn't send any money in to the Trust Fund?

If the amount withheld does not match the amount on your income withholding notice, you should contact your employer. You are responsible for your court ordered child support, even if your employer fails to withhold child support, withholds the wrong amount, or does not send the support to the Trust Fund. Employers are required to send withheld support to the Trust Fund within five days of the withholding. An employer who withholds support but does not send the money to the Trust Fund can be found in contempt of court. You should regularly check your payment/account information to make sure your payments are sent to the Trust Fund.

I work two jobs. Will both employers withhold child support?

They may or may not. The total amount of support that is withheld during a month should equal the amount stated on your income withholding notice whether one or both of your employers withhold support.
