Wisconsin uses the Percentage of Income model. Parenting time credit kicks in at 25% (91 nights/year).
Every overnight above 91 nights/year reduces your payment. Here's how Wisconsin's threshold compares:
Formula Model: Percentage of Income
How It Works: Flat percentage of obligor's gross income. Shared placement formula above 25%.
Parenting Time Threshold: 25% of overnights (91 nights/year)
PT Credit Method: Shared Placement Formula. At 25%+ (92 nights), full shared placement formula kicks in. Both incomes considered.
Wisconsin uses a flat percentage model — one of the simplest in the country. Shared placement formula kicks in at 25%+ overnights.
Based on $6,000/mo income, 2 children, 20% parenting time
In Wisconsin, your parenting time credit activates at 25% of overnights (91 nights/year). Every night above this threshold reduces your payment.
Wisconsin calculates support as a flat percentage of your net income — meaning only your income matters, not your ex's. Focus on documenting deductions accurately.
If your income dropped 20%+ since the last order, you almost certainly qualify for a modification. File promptly — Wisconsin won't backdate reductions.
Most Wisconsin courts allow a modification review every 3 years OR when there's a 20%+ income change — whichever comes first.
Keep a log of every dollar you spend on your kids beyond the order — extracurricular activities, school supplies, clothing. Courts factor documented expenses into deviation requests.

Wisconsin uses the Percentage of Obligor Income model. For one child, support is typically 17% of the obligor's net income. For two children it's 25%, and three children 29%. Flat percentage of obligor's gross income. Shared placement formula above 25%.
Yes. Once your parenting time exceeds 25% of overnights (about 91 nights per year), Wisconsin applies a credit that reduces your obligation. More time with your kids means lower payments.
In Wisconsin, the percentages continue to increase: four children is 31%, five children is 34%, and six or more children is 34%. These are applied to the obligor's net income.
You can request a modification if there's been a substantial change in circumstances — like a 20%+ income change, job loss, new custody arrangement, or the child aging out. Wisconsin courts review modifications based on updated financial worksheets. Most allow a review every 3 years even without a change.
Most Wisconsin modifications are processed in 30–90 days after filing. Some counties offer administrative review (faster, no court date), while others require a hearing. Keep paying your current amount while the review is pending — stopping creates arrears that hurt your case.
Never stop paying — even if you can't afford the full amount. File a modification request immediately. Wisconsin courts can adjust your obligation retroactive to the filing date (not before). Document your financial hardship: pay stubs, termination letters, medical bills. Some counties offer payment plans for arrears.
