Wisconsin collects nearly all child support and maintenance through automatic wage garnishment under Wis. Stat. § 767.75. Income withholding orders take up to 50-65% of disposable earnings, route payments through the state, and have priority over every other garnishment. Since 1988, virtually every Wisconsin support order includes automatic income withholding.

How Wage Garnishment Works for Support in Wisconsin
Wage garnishment for support in Wisconsin is automatic and built into every order under Wis. Stat. § 767.75. Since 1988, all court orders for child support, maintenance, or family support include an automatic income withholding order that directs the paying party's employer to deduct support directly from each paycheck and remit it to the state within 5 days.
Wage garnishment divorce Wisconsin cases rarely require a separate enforcement action because withholding starts at the moment of the order. Upon entry of each support order, the court or county child support agency provides notice of the income assignment by mail or electronic means to the payer's employer. The child support agency typically sends the income withholding order within 2 business days of a new court order. Unless the court finds that withholding would cause the payer irreparable harm, or unless Wis. Stat. § 767.76 applies, the assignment is mandatory. This automatic wage deduction child support mechanism exists because direct payments between former spouses historically failed: payers missed payments, paid late, or stopped entirely. Routing money through the Wisconsin Support Collections Trust Fund creates a verifiable payment record that protects both parties.
What Income Can Be Garnished for Support
Wisconsin garnishes a broad range of income for support under Wis. Stat. § 767.75, not just regular wages. The income withholding order reaches commissions, bonuses, unemployment benefits, workers' compensation, Social Security retirement benefits, and pension payments. Only SSI and W-2 cash assistance benefits are exempt from this support enforcement wage withholding.
The assignment applies to any source from which the payer receives money, making it one of the most comprehensive collection tools in family law. An income withholding order is not limited to a single employer; if a paying parent changes jobs, the new employer must honor the order, and Wisconsin's new-hire reporting system flags job changes to keep collection continuous. Self-employed payers and independent contractors present a harder collection problem because there is no employer to serve, but the county child support agency can pursue alternative remedies including bank levies, tax refund interception, and property liens. For garnished wages alimony obligations specifically, maintenance payments are withheld and routed through the state department or its designee under Wis. Stat. § 767.57, exactly as child support is, ensuring the receiving spouse gets a documented, predictable payment stream rather than relying on voluntary compliance.
Wisconsin Garnishment Limits: How Much Can Be Withheld
Wisconsin follows the federal Consumer Credit Protection Act (CCPA) limits, allowing 50% to 65% of disposable earnings to be withheld for support under Wis. Stat. § 767.75(2r). These limits are far higher than Wisconsin's 20% cap for ordinary consumer debts, reflecting the priority the law places on supporting children and former spouses.
The exact percentage depends on the payer's family situation and arrears status, creating a four-tier structure that every Wisconsin employer must apply:
| Payer Situation | Maximum Garnishment |
|---|---|
| Supports a second family, no arrears (or under 12 weeks behind) | 50% of disposable earnings |
| Supports a second family, more than 12 weeks in arrears | 55% of disposable earnings |
| No second family, no arrears (or under 12 weeks behind) | 60% of disposable earnings |
| No second family, more than 12 weeks in arrears | 65% of disposable earnings |
Disposable earnings are calculated after subtracting only legally required deductions: federal and state income taxes, Social Security, Medicare, and mandatory retirement contributions. Voluntary deductions such as union dues, health insurance premiums, and 401(k) contributions are NOT subtracted before calculating the garnishment, so the withholding base is larger than the worker's net take-home pay. Under Wis. Stat. § 812.30(6), disposable earnings means the part of earnings remaining after deducting Social Security taxes and federal and state income taxes listed on the wage statement.
Income Withholding Orders for Past-Due Support (Arrears)
When a payer falls behind, Wisconsin adds an arrears component to the income withholding order, capped at 50% of the current support amount under Wis. Stat. § 767.75. If a payer falls behind, the agency automatically sends a Notice of Arrears followed by an income withholding order to the employer, typically without a hearing.
The arrears collection rate is limited so that aggressive collection does not push the payer below the federal poverty line established under 42 U.S.C. § 9902(2). The maximum amount subject to assignment to collect an arrearage is 50% of the support currently due. As a concrete example clarified in the statutory annotations, a 25% wage assignment for current support limits an arrearage assignment to an additional 12.5% of wages. This means total withholding for current support plus arrears still cannot exceed the overall CCPA ceiling of 50% to 65%. Past-due support garnishment continues automatically until the arrears are paid in full or the court or agency modifies the order. Wisconsin also charges an annual receiving-and-disbursing fee of $65 per year to each party ordered to make payments, and this fee is itself collectible through income withholding under Wis. Stat. § 767.57.
Employer Obligations and Penalties in Wisconsin
Wisconsin employers must begin withholding support no later than the first pay period occurring within 5 working days of the income withholding notice under Wis. Stat. § 767.75. The employer must then forward the withheld amount to the Wisconsin Support Collections Trust Fund within 5 days of paying the employee, and may charge the employee a processing fee of up to $3.00 per withholding.
Employers face real penalties for noncompliance. An employer who fails to withhold or remit support may be held in contempt under Chapter 785 or proceeded against under Chapter 778, forfeiting not less than $50, or, if the unwithheld amount exceeds $50, an amount equal to 1% of the sum not withheld or sent. Critically, Wisconsin law protects employees from retaliation: no employer may use an income assignment as a basis for denying employment, discharging an employee, or taking disciplinary action. An employer who violates this anti-retaliation rule faces a fine of up to $500 and may be ordered to make full restitution, including reinstatement and back pay. The $3.00 employer fee is deducted from the employee's remaining wages, not from the support payment itself, and it does not reduce the employee's gross income for purposes of recalculating support amounts.
Priority of Support Garnishments Over Other Debts
Support withholding takes top priority over every other garnishment in Wisconsin under Wis. Stat. § 767.75. A withholding assignment or order for support has priority over any other assignment, garnishment, or similar legal process under state law. Even Wisconsin Department of Revenue tax wage attachments yield to past-due child support.
When a worker faces both a support withholding order and an ordinary creditor garnishment, the support amount is deducted first, and the consumer creditor receives only what remains within the 25% limit minus the support deduction. In practice, a payer with a 50% support garnishment may have nothing left available for a credit-card or medical-debt garnishment, because the support order consumes the available disposable income first. This priority rule applies regardless of which garnishment was filed first in time. The automatic wage deduction child support order always jumps to the front of the line. This protection ensures that children and former spouses are paid before commercial creditors, reflecting the public-policy judgment that family support obligations outrank ordinary debt collection.
Interstate Support Orders (UIFSA) in Wisconsin
Wisconsin honors out-of-state income withholding orders under the Uniform Interstate Family Support Act (UIFSA), so all Wisconsin employers must comply with support orders received from other states. When an employer receives an out-of-state order, it follows the laws of the employee's work state to determine withholding limits, disposable earnings, timing, and fees.
This interstate cooperation means a parent who moves to Wisconsin cannot escape a support obligation established elsewhere, and a Wisconsin order follows a payer who relocates out of state. For an out-of-state order processed by a Wisconsin employer, the employer applies Wisconsin's rules on when to begin withholding (first pay period within 5 working days), how to define disposable earnings, when to remit (within 5 days), the proper administrative fee (up to $3.00), and how to allocate multiple orders. UIFSA prevents conflicting orders by establishing that only one state holds continuing exclusive jurisdiction over a support order at a time. Wisconsin's participation in this nationwide framework, combined with federal new-hire reporting and the Federal Parent Locator Service, makes cross-border support evasion extremely difficult and keeps garnished wages alimony and child support flowing across state lines.
Enforcement When Wages Cannot Be Garnished
When wage garnishment is impossible because a payer is self-employed or unemployed, Wisconsin deploys additional enforcement tools under Wis. Stat. § 767.57(1h). The county child support agency or a circuit court commissioner may pursue contempt proceedings under Chapter 785, money judgments, tax refund interception, bank levies, and property liens to secure unpaid support.
Contempt is the most powerful remedy. A court may impose fines, additional wage garnishment, or even jail time if a payer willfully refuses to pay support. Wisconsin courts can also suspend driver's, professional, and recreational licenses for support nonpayment, and report delinquent payers to credit bureaus. For arrears that have accumulated into a fixed sum, the receiving party can obtain a money judgment, which then enables collection through bank-account levies, real-estate liens, and seizure of tax refunds. Importantly, a payer who experiences a genuine drop in income must keep paying the existing support order until a judge formally modifies it. Stopping payments unilaterally, even after a job loss, exposes the payer to a show-cause hearing, fines, and potential incarceration. The support enforcement wage system is designed so that nonpayment carries escalating, well-documented consequences.
