Child Support Garnishment Rules by State

Child support garnishment can take 50-65% of your disposable earnings — far more than consumer debt. Here's how the rules work in every state.

Child support wage garnishment follows different rules than consumer debt garnishment, and the amounts can be significantly higher. While consumer debt garnishment is capped at 25% of disposable earnings under federal law, child support can reach up to 65% of your disposable income. Understanding these rules is essential for anyone paying child support through wage withholding.

Federal Child Support Garnishment Limits

The Consumer Credit Protection Act sets the following federal limits for child support garnishment, which apply in all 50 states:

If You Are Currently Supporting Another Spouse or Child

  • 50% of disposable earnings (current support only)
  • 55% of disposable earnings (if 12+ weeks in arrears)

If You Are NOT Supporting Another Spouse or Child

  • 60% of disposable earnings (current support only)
  • 65% of disposable earnings (if 12+ weeks in arrears)

The distinction between "supporting another family" and "not supporting another family" is critical. If you have remarried and are supporting your new spouse or have other children, the lower percentages apply. If you are single with no other dependents, the higher percentages apply.

How Child Support Garnishment Differs from Consumer Debt

Child support garnishment has several unique characteristics that set it apart from consumer debt garnishment:

State-by-State Variations

While the federal limits apply nationwide, states can implement additional rules and procedures. Check out our state pages for detailed info.

Income Withholding Orders

All states are required to use income withholding as the primary method of child support collection under federal law. When a child support order is established, an income withholding order is typically issued simultaneously. Your employer is legally required to comply.

State-Specific Considerations

Some states have specific rules that affect how child support garnishment is calculated:

What Counts as "Disposable Earnings" for Child Support

For child support purposes, disposable earnings are calculated similarly to consumer debt: gross earnings minus legally required deductions (taxes, Social Security, Medicare). However, some states include additional income sources in the calculation, such as bonuses and commissions, overtime pay, tips, rental income, and investment income. Voluntary deductions like 401(k) contributions are generally not subtracted from earnings for child support calculation purposes, though some courts may allow reasonable retirement contributions.

When Child Support and Consumer Debt Garnishment Overlap

If you have both child support and consumer debt garnishments, child support takes absolute priority. The consumer debt garnishment can only take what remains within the legal limits after child support is satisfied. In practice, if child support is already taking 50-65% of your disposable earnings, there is usually no room left for consumer debt garnishment.

How to Modify Child Support Garnishment

If your financial circumstances have changed significantly, you can petition the court to modify the child support order. Valid reasons for modification include job loss or significant income reduction, disability or serious illness, the child's needs have changed, or the other parent's income has significantly increased. You must continue paying the current amount until the court officially modifies the order. Stopping payments on your own can result in contempt of court charges.

Arrears and Back Support

If you fall behind on child support payments, the additional 5% garnishment for arrears can be applied. Arrears also accrue interest in many states, and the total amount owed can grow substantially over time. Some states charge 6-12% interest on child support arrears. Additionally, falling behind can trigger other enforcement actions including license suspension, passport denial, and even jail time in extreme cases.
