Child Support

In Wisconsin, child support is calculated using a set of guidelines published in the Wisconsin Administrative Code. These guidelines were formerly published in Chapter HSS 80 and DWD 40, and many people still refer to them as the “HSS 80″ or “DWD40″ guidelines”.

With the reorganization of the Wisconsin Administrative Code, these guidelines are now in the regulations for the Department of Children and Families, found in Chapter DCF 150. You can see DCF 150 and the rest of the Administrative Code at the Wisconsin Legislature Legislative Reference Bureau’s Administrative Code web page.

In general, the guidelines require a person paying child support to pay a percentage of their gross income (income before deductions) as child support. The guidelines are:

* 17% for 1 child
* 25% for 2 children
* 29% for 3 children
* 31% for 4 children
* 34% for 5 or more children

DCF 150 provides formulas for calculating child support for situations where all the children live with one parent, where they spend substantial time with both parents, or where each parent has some of the children.

There are online sites that allow you to calculate your child support by filling in certain information. You can also get spreadsheets that will help you do the calculations, as well as other information, at the Wisconsin Department of Children and Families website.

Terminating Support at Age 18 or High School Graduation

The obligation to pay child support continues until age 18, or until age 19 if the child is pursuing a high school diploma or equivalent.

To terminate support at that time, the payor can hire an attorney to do the necessary paperwork, or may contact the Green County Child Support Agency and ask that the child support order be terminated. The Child Support Agency must be provided with proof that the child is 18 years old and has graduated from high school, or the date the child will be graduating.

While current support for the specific child will end, any support obligation for other children will continue. In addition, any wage assignment will not end until all debts have been paid in full, including receiving and disbursing fees.
