Child Support Garnishment: Limits, Enforcement, and Penalties

Federal law sets the ceiling on child support garnishment limits at 50% to 65% of your disposable earnings, depending on whether you support other dependents and whether you owe back payments. The money is withheld from each paycheck before you see it, sent by your employer to a state disbursement unit, and routed from there to the custodial parent. For most support orders issued since 1994, this withholding is automatic.

The Percentage Caps

The Consumer Credit Protection Act sets the maximum share of a paycheck that can go to support. The limits apply to disposable earnings, meaning your pay after legally required deductions like federal and state taxes, Social Security, and Medicare. Gross pay doesn’t enter the calculation.¹

Two questions decide which cap applies: do you support another spouse or child, and are you behind on payments by more than 12 weeks?

50% if you support another spouse or child not covered by the order.
55% in that same situation, with arrears more than 12 weeks old.
60% if you have no other spouse or dependent child to support.
65% with no other dependents and arrears more than 12 weeks overdue.

These are absolute maximums. No combination of support orders can push withholding past the applicable threshold, regardless of how many children or custodial parents are involved.² When a parent owes under multiple orders, the employer’s state determines how to allocate the available funds among recipients.³

Child support generally outranks other wage garnishments in practice. The CCPA caps consumer debt garnishment at 25% of disposable earnings but permits up to 65% for support, so when a support order is already taking a large share, little or nothing remains for a credit card judgment or car loan garnishment to reach.⁴

What Counts as Earnings

The federal definition reaches further than a salary. Earnings include wages, commissions, bonuses, other compensation for personal services, and periodic pension and retirement payments.¹ Federal workers and military members aren’t exempt. Federal pay, military retired pay, Social Security benefits, workers’ compensation, railroad retirement benefits, and certain veterans’ disability payments can all be garnished for child support.⁵

A parent who retires or shifts to military disability pay doesn’t escape the obligation. The garnishment follows the income to its new source.

How the Withholding Reaches the Other Parent

Every child support garnishment moves through a standardized federal form called the Income Withholding for Support order. It’s the only form employers are required to accept and is used in every state and tribal jurisdiction. The order lists both parents’ names and Social Security numbers, the children covered, the court case number, and exact dollar amounts for current support and any arrears balance.⁶

Payments go to the state disbursement unit, not directly to the other parent. Every state operates one of these units to track payments and maintain records.⁶ A child support agency, court, or attorney can issue the form. Without one, an employer has no legal basis to start deducting.

Once a valid order arrives, federal law requires the employer to send withheld amounts to the state disbursement unit within seven business days of each payday.³ The timeline for starting that first deduction after the order arrives varies by state. Most states allow employers to charge a small administrative fee per pay period for processing the withholding, deducted from the employee’s pay on top of the support amount.⁷

Employers who ignore an order face real consequences. Federal law makes the employer liable for the full amount they failed to withhold, and states can add their own fines.³ The withholding order carries the same weight as a direct court order.⁷

Can You Be Fired for a Garnishment?

No. Federal law prohibits an employer from firing you because your wages are being garnished for a single debt.⁸ A child support order counts as one debt for this purpose, even when it covers both current support and arrears. Federal child support law goes further by requiring states to penalize any employer who fires, refuses to hire, or disciplines a worker because of a support withholding order.³

Self-Employment and Independent Contractors

Standard wage garnishment assumes there’s a payroll department to intercept the money. For self-employed parents and independent contractors, enforcement looks different. A withholding order can technically be sent to a contractor’s client, directing them to withhold from payments before they reach the contractor, but this is hard to sustain when the contractor has many short-term clients or receives one-time payments.⁹

Figuring out how much to withhold is also harder. A contractor’s payment covers business expenses and self-employment taxes alongside personal income, and most states lack clear statutory guidance on what portion of a payment should count as garnishable.⁹ Courts may average irregular earnings over several months or years to set a realistic amount. When wage withholding isn’t practical, agencies turn to levying bank accounts, intercepting tax refunds, or seizing assets.

What Happens If You Fall Behind

Garnishment is the starting point, not the whole toolkit. The further behind a parent falls, the more enforcement options the state and federal governments can trigger.

Passport Denial

Owe more than $2,500 in past-due child support and the State Department will deny your passport application or renewal. State child support agencies certify delinquent cases to the federal Office of Child Support Services, which forwards them to the State Department for its screening system.¹⁰ An existing passport can also be revoked.

License Suspension

Federal law requires every state to maintain procedures for suspending driver’s licenses, professional and occupational licenses, and recreational licenses when a parent owes overdue support or ignores court orders related to paternity or support proceedings.³ Each state sets its own arrears threshold and notice period. For parents who drive for a living or hold a professional license, this is often the harshest step.

Tax Refund Interception

The Federal Tax Refund Offset Program lets states intercept part or all of a delinquent parent’s federal refund. State agencies submit the name, Social Security number, and arrears amount to the Treasury Department, which matches the data against incoming refunds and redirects the money.¹¹ The parent receives notice before the offset, but once the process is in motion, the refund is gone.

Criminal Charges

Willful nonpayment of support across state lines is a federal crime. If support has gone unpaid for more than one year or arrears exceed $5,000, a first offense carries up to six months in prison. When arrears top $10,000 or the obligation has been unpaid for more than two years, the penalty rises to up to two years.¹² State courts can also hold a nonpaying parent in contempt. Criminal prosecution is uncommon and reserved for cases where a parent clearly has the ability to pay but refuses.

Modifying or Ending a Garnishment

A garnishment doesn’t run forever, but it also doesn’t stop on its own. The common endings are the child reaching the age of majority (18 in most states, though some extend to 19 or through college) or full payment of all current and back support. Either way, the employer needs a formal termination notice or a new court order before deductions stop.

If your income drops or your circumstances change significantly, you can petition the court to modify the support amount. Most states require a substantial change in circumstances, and many set a specific threshold such as a 20% change in income before they’ll revisit the order. A modification isn’t retroactive to the date your situation changed. It takes effect only from the date you file or the date the court issues a new order. Waiting months to file while falling further behind creates arrears that a later modification can’t erase.

Changing Jobs

Leaving a job doesn’t make the garnishment disappear. Your former employer is required to notify the state child support agency, which will locate your new employer and send a fresh withholding order.³ Federal new-hire reporting helps states find the new income source quickly. During any gap, you still owe support. Payments missed in that window become arrears, and in many states arrears accrue interest. Contacting your state child support agency before you switch jobs can keep a short gap from turning into an enforcement problem.
