How does shared placement affect child support in Wisconsin?
Wisconsin applies a shared placement formula when the non-custodial parent has the child for at least 25% of overnight placements (92 or more nights per year).

Is there an income cap for child support in Wisconsin?
Wisconsin does not have a statutory income cap for child support. However, courts may use discretion to adjust the support amount for high-income payers if applying the standard percentage would exceed the reasonable needs of the child. In such cases, the court considers the child's actual needs and standard of living.
How long does child support last in Wisconsin?
In Wisconsin, child support generally continues until the child turns 18, or until age 19 if the child is still pursuing a high school diploma or GED equivalent. Support for a child with a disability may continue beyond age 18 if the child is unable to be self-supporting.
