Wisconsin aggressively enforces unpaid child support through a comprehensive system of administrative and judicial remedies. Under Wis. Stat. § 767.511(6m), unpaid child support accrues interest at 1% per month (12% annually) on any arrears equal to or exceeding one month of support. The Wisconsin Bureau of Child Support, operating through 72 county child support agencies, deploys enforcement tools including wage garnishment of up to 65% of disposable income, federal and state tax refund intercepts, passport denial for arrears exceeding $2,500, suspension of driver's and professional licenses, and contempt proceedings carrying penalties of up to 6 months in jail. Parents who willfully fail to pay for 120 or more consecutive days face misdemeanor charges with fines up to $10,000 and 9 months imprisonment, while arrears exceeding $10,000 can trigger felony prosecution with up to 5 years in prison.

How Wisconsin Calculates Interest on Unpaid Child Support
Wisconsin mandates 1% monthly simple interest (12% annually) on child support arrears equal to or greater than one month's obligation under Wis. Stat. § 767.511(6m). Interest accrual is automatic and mandatory—courts have no discretion to waive it even if doing so would be equitable. When the paying parent no longer has a current support obligation, interest at 1% per month accrues on the total arrears balance. Some Wisconsin counties participate in a pilot program with a reduced rate of 0.5% per month.
For example, if a parent owes $5,000 in arrears with monthly support of $800, the arrears exceed one month's obligation, triggering interest. At 1% monthly, this parent accrues $50 per month in interest alone, adding $600 per year to the debt. Over 5 years without payment, a $5,000 balance would grow to $8,000 or more through compounding interest.
The Wisconsin Department of Children and Families (DCF) tracks all interest calculations through the Wisconsin Support Collections Trust Fund (WI SCTF). Interest continues to accrue even after the child turns 18 until the arrears balance reaches zero.
Wage Garnishment for Child Support in Wisconsin
Wisconsin law permits wage garnishment of up to 65% of disposable earnings for child support enforcement, making it one of the most aggressive garnishment states in the nation. Under federal law (Consumer Credit Protection Act, 15 U.S.C. § 1673) and Wisconsin Administrative Code DCF 152, garnishment limits depend on the paying parent's circumstances and delinquency status.
The garnishment tiers work as follows: Parents currently supporting another spouse or child face a maximum garnishment of 50% of disposable earnings. Parents not supporting another spouse or child face a maximum of 60%. An additional 5% may be garnished if arrears are more than 12 weeks past due, bringing the maximum to 55% or 65% respectively.
Wage withholding in Wisconsin is immediate upon entry of a support order—the court sends an Income Withholding Order directly to the employer without waiting for delinquency. Employers who fail to comply face penalties including fines and legal action. Garnishment extends beyond traditional wages to unemployment benefits, workers' compensation payments, and Social Security benefits (excluding Supplemental Security Income).
Tax Refund Intercept Program in Wisconsin
The Wisconsin child support program intercepts both state and federal tax refunds when arrears meet specific thresholds. For federal tax intercept eligibility under Wis. Stat. § 49.855, three conditions must be met: the past-due amount owed to the family must be $500 or more (or $150 or more if any amount is assigned to the state), the child support agency must have the parent's Social Security number, and the case must receive case-management services from a local child support agency.
State tax refund intercepts follow similar criteria. The DCF also intercepts Wisconsin State Lottery winnings of $1,000 or more. When a parent files a joint tax return with a new spouse, the non-obligated spouse may file Form 8379 (Injured Spouse Allocation) to protect their share of the refund.
The tax intercept process is automatic once thresholds are met. Parents receive notice before interception and have limited appeal rights based on identity mistakes or factual errors. Intercepted funds first satisfy assigned (public assistance) arrears, then family arrears, following federal distribution rules.
Passport Denial for Child Support Arrears
The U.S. State Department denies passport issuance or renewal to any parent certified for federal tax intercept with $2,500 or more in child support arrears under 42 U.S.C. § 652(k). This threshold includes all unpaid support, fees, costs, and interest. Once certified, passport denial remains in effect until the debt is paid in full—partial payment does not restore passport eligibility.
Exceptions to passport denial are extremely limited: identity mistakes or factual errors about the debt, or documented life-or-death emergencies involving immediate family members (verified by a doctor or the Red Cross). Business travel, vacations, or general hardship do not qualify as exceptions.
Parents denied passports may negotiate payment plans with their county child support agency. A satisfactory payment plan may prevent future tax intercept certification, but does not automatically restore passport privileges once denied. The parent must clear the $2,500 threshold or make payment arrangements acceptable to the child support agency.
License Suspension for Unpaid Child Support
Wisconsin suspends driver's licenses, professional licenses, and recreational licenses when child support arrears reach 300% of the monthly support obligation or $1,000, whichever is greater, under Wis. Stat. § 49.857. The Wisconsin Child Support Lien Docket adds a parent's name when unpaid support reaches $500, creating the foundation for license enforcement.
The suspension process requires two warning notices before action. The first notice informs the parent of potential license action and the opportunity to establish a payment plan. The second notice confirms the intent to certify the parent to licensing authorities. Administrative enforcement actions are stayed while the parent negotiates a payment plan with the child support agency.
Licenses affected include Wisconsin driver's licenses (through the Department of Transportation), professional and occupational licenses (through the Department of Safety and Professional Services), and recreational licenses including hunting and fishing permits (through the Department of Natural Resources). License reinstatement requires either full payment of arrears or entry into an approved payment plan.
Contempt of Court for Child Support Violations
Wisconsin courts hold parents in civil contempt under Wis. Stat. Chapter 785 when they willfully fail to pay court-ordered child support. Contempt requires proof that the parent had the ability to pay but chose not to—courts cannot punish inability caused by job loss or serious illness. The contempt process distinguishes between remedial (civil) contempt designed to compel compliance and punitive (criminal) contempt designed to uphold court authority.
Civil contempt penalties include imprisonment for up to 6 months per violation under Wis. Stat. § 785.04(1)(a), though courts must provide a "purge condition" allowing the parent to avoid or end imprisonment by making specified payments. Purge conditions must be within the parent's ability to meet and reasonably related to the contempt. Common purge conditions include a lump-sum payment, a monthly payment schedule, or both.
If the parent fails to meet purge conditions, the court may lift the stay on the remedial sanction and issue a bench warrant for commitment to county jail. Upon release, the parent still owes all arrears, and subsequent contempt proceedings may follow until full payment.
Criminal Prosecution for Child Support Nonpayment
Wisconsin prosecutes willful child support nonpayment as a crime under Wis. Stat. § 948.22. A parent who willfully fails to pay for 120 or more consecutive days commits a Class I felony or Class A misdemeanor depending on circumstances. Misdemeanor nonsupport carries penalties of up to 9 months in jail and fines up to $10,000.
Felony charges apply when arrears exceed $10,000 or when the parent has prior nonsupport convictions. Felony nonsupport is a Class I felony punishable by up to 3.5 years in prison, though some aggravated cases may carry up to 5 years. Prosecutors must prove the parent had the financial ability to pay but deliberately avoided the obligation.
Criminal prosecution differs from civil contempt in several ways: criminal cases require proof beyond a reasonable doubt rather than clear and convincing evidence, conviction creates a criminal record, and incarceration is punitive rather than coercive. Criminal prosecution typically targets chronic, willful non-payers rather than parents experiencing temporary financial hardship.
Federal Enforcement Actions Against Wisconsin Parents
Federal child support enforcement supplements Wisconsin's state remedies through several mechanisms. The Federal Parent Locator Service helps locate parents across state lines using Social Security records, IRS data, and other federal databases. The Uniform Interstate Family Support Act (UIFSA), adopted in Wisconsin under Wis. Stat. Chapter 769, enables enforcement of Wisconsin orders in other states and vice versa.
Federal criminal prosecution under 18 U.S.C. § 228 (Child Support Recovery Act) targets parents who flee Wisconsin to avoid support obligations. Interstate flight to avoid support is a federal felony carrying up to 2 years imprisonment for first offenses and up to 5 years for subsequent offenses or arrears exceeding $10,000.
The Federal Offset Program intercepts federal payments beyond tax refunds, including federal retirement benefits and certain federal contractor payments. Administrative wage garnishment can follow parents to federal employment. Credit bureau reporting of child support delinquency damages the parent's credit score and financial opportunities.
Payment Plans and Arrears Reduction Programs
Wisconsin offers payment plans to help parents address child support arrears while avoiding aggressive enforcement. Parents can request payment plans at any time through their county child support agency. Plans may include lump-sum payments, monthly installments, or both, structured to fit the parent's financial situation.
A compliant payment plan may stop tax refund intercepts, prevent lump-sum intercepts from public retirement funds, and halt passport denial proceedings. Payment plans are negotiated between the parent and the child support agency, with court review available if the parties cannot agree on reasonable terms.
Wisconsin does not have a formal arrears forgiveness program for family-owed arrears, but the state may negotiate compromise on state-owed arrears (from periods when the custodial parent received public assistance). Any compromise of state-assigned arrears requires approval from the DCF. Interest may continue to accrue even during payment plan compliance unless specifically addressed in the plan terms.
Statute of Limitations on Child Support Arrears
Wisconsin imposes a 20-year statute of limitations on collecting child support arrears under Wis. Stat. § 893.40. The 20-year period begins when the youngest child emancipates or reaches the age of majority (18, or 19 if still in high school)—not from the date support was due or the date of the last order.
Arrears remain fully enforceable throughout this period, including all accrued interest. Contempt proceedings remain appropriate to enforce arrearages even after the child reaches majority. The receiving parent or the state may pursue collection through any available enforcement remedy during the 20-year window.
After 20 years, the statute of limitations bars enforcement action, though payments made voluntarily are valid. The statute applies to the enforcement remedy, not to the underlying debt—the obligation technically remains but cannot be judicially enforced.
How to Request Child Support Enforcement in Wisconsin
Parents owed child support can request enforcement through their county child support agency or by filing a motion directly with the circuit court. The DCF operates child support agencies in all 72 Wisconsin counties, providing enforcement services at no cost to the receiving parent.
To initiate enforcement, contact your county child support agency with documentation of the court order, payment history, and any known information about the paying parent's employment or assets. The agency will review available enforcement tools and select appropriate remedies. Agency enforcement is administrative and typically faster than court proceedings.
For court-based enforcement, file a motion for contempt in the circuit court that issued the original support order. The filing fee is $184.50, or $194.50 if the motion includes additional support requests (as of March 2026; verify with your local clerk). Low-income filers earning at or below 125% of federal poverty guidelines ($19,506 for individuals in 2026) may qualify for fee waivers using Form CV-410A.
What Paying Parents Should Do When They Cannot Pay
Parents who cannot meet child support obligations due to job loss, illness, or other hardship should act immediately rather than accumulate arrears. Wisconsin courts cannot modify past-due support, but can adjust future payments based on changed circumstances. File a motion to modify support as soon as circumstances change—reductions apply only from the filing date forward.
Contact your county child support agency to explain the situation and explore payment plan options before enforcement actions begin. Maintain documentation of job search efforts, medical conditions, or other factors affecting ability to pay. Courts evaluate willfulness based on conduct, so demonstrating good faith effort matters.
Never ignore court notices or enforcement letters. Failure to respond to contempt proceedings results in default judgments and potential bench warrants. Appearing in court and explaining circumstances is far better than avoiding the process. Courts can impose suspended sentences, payment plans, and other accommodations for parents making genuine efforts.
