Wage Garnishment for Child Support: Federal Limits and Priority

Wage garnishment for child support can take between 50% and 65% of your disposable earnings, and it outranks nearly every other debt a creditor or employer can collect against. The exact percentage depends on whether you support another spouse or child and whether you are more than 12 weeks behind on payments. These federal caps come from the Consumer Credit Protection Act and apply the same way in every state, no matter which court issued the support order.

The Four Federal Percentage Limits

The Consumer Credit Protection Act sets four garnishment ceilings for child support, keyed to two questions: does the employee support another spouse or dependent child not covered by the order, and are payments more than 12 weeks in arrears.¹

50% of disposable earnings if the employee supports another spouse or dependent child and payments are current.
55% if the employee supports another spouse or dependent child but is more than 12 weeks behind.
60% if the employee does not support another spouse or dependent child and payments are current.
65% if the employee does not support another spouse or dependent child and is more than 12 weeks behind.

These are absolute ceilings across all support-related withholdings combined. If a court order demands more than the applicable percentage, the employer withholds only up to the legal cap. An employee with no other dependents earning $1,000 in disposable income who is in arrears cannot lose more than $650 from that paycheck, whatever the order says.¹

Picking the wrong tier is a real risk for employers. Using the 60% rate when the employee actually supports other dependents can create financial hardship and invite legal challenges, so the family-status question needs to be verified before the first paycheck is cut.

What “Disposable Earnings” Actually Means

The percentages do not apply to gross pay, and they do not apply to typical take-home pay. They apply to disposable earnings, which is gross pay minus only the deductions required by law.² The mandatory deductions are federal, state, and local income taxes plus Social Security and Medicare. Nothing else.

That catches people off guard. Health insurance premiums, life and disability coverage, 401(k) contributions, union dues, and charitable giving are all voluntary for this calculation, even if they come out of every check automatically. An employer cannot subtract them before applying the garnishment percentage. If you earn $5,000 gross and have $1,200 in mandatory taxes plus another $500 in health insurance and retirement contributions, your disposable earnings are $3,800, not $3,300. The 50% to 65% cap applies to the $3,800 figure.²

Over-withholding violates the employee’s federally protected income rights. Under-withholding leaves the employer on the hook for the shortfall. Both directions carry consequences.

Where Child Support Ranks Against Other Debts

When several garnishment orders arrive for the same employee, federal law puts child support first. Commercial creditor garnishments for credit card debt, personal loans, or similar judgments wait until the support obligation is fully withheld. Student loan administrative garnishments and most other government-initiated withholdings also fall below child support.

IRS tax levies are the one place the ranking turns on timing. An IRS levy only takes priority over child support if the levy was entered before the child support withholding order.³ When a child support order is already in place, federal tax law exempts from IRS levy whatever portion of wages is needed to comply with that existing court-ordered support.⁴ If an employer receives a later IRS levy while already honoring a child support order, the IRS tells the employer to notify the agency so it can arrange alternative collection.

Bonuses, Commissions, and Other Pay

Child support withholding reaches further than the regular paycheck. Under the Consumer Credit Protection Act, “earnings” covers any compensation paid for personal services, whether it is called wages, salary, commission, or bonus. Pension and retirement payments count too.²

Lump sum payments get particular attention. The Department of Labor treats bonuses, sign-on payments, commissions, severance, retroactive raises, vacation payouts, and productivity awards as earnings subject to the same CCPA limits as regular wages.⁵ The test is whether the payment was made in exchange for personal services. A reimbursement for equipment is not earnings; a performance bonus is. Many states require employers to notify the child support agency 30 to 45 days before issuing a lump sum, so the agency can intercept arrears.⁶

Military Pay

Active-duty service members are subject to the same percentage caps. The Defense Finance and Accounting Service processes child support withholding from military pay under the 50% to 65% framework based on the service member’s dependents and arrears.⁷ DFAS applies the caps only when disposable earnings cannot cover the full ordered amount, and it allocates on a pro-rata basis when more than one order exists.

When There Is More Than One Support Order

If two or more child support orders arrive for the same employee and the combined total exceeds the percentage cap, the employer has to divide the available funds. Most jurisdictions use pro-rata distribution: each order gets a share proportional to the amount it represents relative to the total owed. An order for $600 and an order for $400 would receive 60% and 40% of the available withholding.

Some jurisdictions use equal distribution instead, splitting the available funds evenly between orders regardless of their size. The state where the employee works controls which method applies, along with allocation priorities and processing timelines.⁸ An employer who can show exactly how it divided funds and why stands on much firmer ground if a parent or agency later questions the split.

Job Protection and the Income Floor

Federal law bars an employer from firing an employee because wages are being garnished for a single debt, no matter how many separate garnishment proceedings are brought to enforce that one debt.⁹ An employer who deliberately violates this rule faces a fine of up to $1,000, up to one year in prison, or both. One child support case cannot be grounds for termination, even if several garnishment actions have been filed to enforce it. The statute does not extend the same protection to employees garnished for two or more separate debts.

The percentage caps also function as an income floor. Even for employees in serious arrears, at least 35% of disposable earnings stays untouchable, and often 45% or 50% does.¹

Contesting or Modifying an Order

Employees who believe a withholding order is wrong have options. Common grounds for challenge include mistaken identity, an incorrect arrears balance, or a withholding amount that does not match the underlying court order. Every state must provide a review process, and requests usually have to go in writing within a short window after the order arrives.

Modification is a separate path. If circumstances have changed through job loss, a serious medical condition, or a significant income drop, federal law requires states to have procedures for reviewing and adjusting support orders when a parent shows a substantial change in circumstances.¹⁰ The request goes to the court or agency that issued the original order. The existing withholding stays in place until a new order is entered. Ignoring the garnishment while waiting on a hearing is one of the fastest ways to pile up arrears and trigger the 55% or 65% tier.

Employer Timelines and Penalties

Once an employer receives an Income Withholding for Support order, the federal standardized form used in every state, withholding usually must start by the next pay period. The employer then has seven business days after the date the employee would otherwise have been paid to send the money to the state disbursement unit.⁸ The state disbursement unit then has two business days to distribute the payment.¹¹ When the order comes from a different state than where the employee works, the employer follows the employment state’s rules for processing fees, maximum withholding, timelines, and allocation.

Employers who fail to honor a valid withholding order can be held liable for the full amount that should have been withheld, plus additional fines set by state law. Most states allow the employer to charge the employee a small administrative fee for processing, typically a few dollars per pay period, with the amount set by state law rather than federal rule.¹²
