An income withholding order for child support is a court or agency directive that requires an employer to deduct a set amount from an employee’s pay and send it to a state disbursement unit. Federal law caps the deduction at 50% to 65% of disposable earnings, depending on whether the employee supports a second family and whether they are more than 12 weeks behind. For the worker, it means a smaller paycheck until the obligation ends. For the employer, compliance is mandatory: ignoring the order creates liability for the full amount that should have been withheld.
What the Order Is and What It Says
Every income withholding order uses the same federal form, titled “Income Withholding for Support.”1Administration for Children and Families. Income Withholding for Support (IWO) Form, Instructions and Sample The form is standardized nationwide, which matters when an order issued in one state is sent to an employer in another.
The form identifies the employee who owes support (the obligor), the person receiving support (the obligee), and the case number. It breaks the withholding into specific dollar amounts: current monthly support, any past-due balance, and medical support obligations. It also lists the exact address of the State Disbursement Unit where every payment must be sent.2Administration for Children and Families. Income Withholding for Support
What Income the Order Reaches
Withholding applies to far more than a regular paycheck. Federal law defines covered income to include wages, salaries, commissions, bonuses, severance pay, sick pay, workers’ compensation, disability payments, pensions, and retirement benefits.3Office of the Law Revision Counsel. 42 USC 659 – Consent by United States to Income Withholding, Garnishment, and Similar Proceedings for Enforcement of Child Support and Alimony Obligations Reimbursements for work expenses are excluded, as are certain military allowances necessary for duty performance.
A year-end bonus, a commission check, or a severance package all fall within the scope of the order. Payroll staff need to flag every form of compensation an affected employee receives, not just base salary.
How Much Can Be Withheld
The Consumer Credit Protection Act sets the ceiling. The cap is based on disposable earnings, meaning what’s left after subtracting deductions required by law: federal and state income taxes, Social Security, and Medicare.4Office of the Law Revision Counsel. 15 USC 1673 – Restriction on Garnishment Voluntary deductions, like health insurance premiums and 401(k) contributions, don’t reduce the disposable earnings figure. Net pay and disposable earnings are not the same number.
The federal maximum depends on two factors: whether the employee supports another spouse or child, and whether they are more than 12 weeks in arrears.
- 50% if the employee supports a second spouse or dependent child
- 55% if supporting a second family and more than 12 weeks in arrears
- 60% if the employee does not support a second spouse or dependent child
- 65% if not supporting a second family and more than 12 weeks in arrears
These are federal maximums.4Office of the Law Revision Counsel. 15 USC 1673 – Restriction on Garnishment Some states set lower caps, and when they do, the employer must apply whichever limit results in less being withheld.5U.S. Department of Labor. Fact Sheet 30 – Wage Garnishment Protections of the Consumer Credit Protection Act The state whose limits apply is the state where the employee works, not the state that issued the order.6Office of the Law Revision Counsel. 42 USC 666 – Requirement of Statutorily Prescribed Procedures to Improve Effectiveness of Child Support Enforcement
How Employers Must Process the Order
Once an employer receives a valid order, withholding must begin with the next regular pay cycle. Federal law doesn’t require employers to alter their normal pay schedule to start earlier, but the employer becomes liable for any amount it fails to withhold after proper notice.6Office of the Law Revision Counsel. 42 USC 666 – Requirement of Statutorily Prescribed Procedures to Improve Effectiveness of Child Support Enforcement Waiting a cycle to “figure things out” is where employers get into trouble.
After withholding the funds, the employer must send the payment to the State Disbursement Unit within seven business days of payday.7Administration for Children and Families. Remitting Payments – Answers to Employers Questions Some states impose shorter deadlines. Payments go to the address specified on the form, typically through electronic funds transfer or the state’s online portal. Keep records of every deduction date and every remittance date; those records are the employer’s defense if a discrepancy comes up later.
Most states allow employers to retain a small administrative fee to offset processing costs, ranging from about $1 to $5 per payment.8Office of Child Support Services. Income Withholding Orders for Child Support The fee is optional. The form and state law specify the maximum allowed.
Employers that handle withholding orders in volume can register for the federal e-IWO system, which delivers and acknowledges orders electronically at no cost.9Administration for Children and Families. Electronic Income Withholding Order (e-IWO) Overview
Multiple Orders and Priority Over Other Garnishments
When an employee has withholding orders from more than one child support case, the employer cannot pay them first-come, first-served. Every current support obligation must be addressed.10Administration for Children and Families. Processing an Income Withholding Order or Notice If disposable earnings aren’t enough to cover all orders in full, the employer must follow the allocation method of the employee’s principal state of employment. States generally use one of two approaches:
- Proration. Each order gets a share of the available funds based on its percentage of total current support owed. A $600 order paired with a $400 order gets 60% and 40% of the available funds, respectively.
- Equal division. Available funds are split evenly among all orders regardless of each order’s dollar amount.
Child support withholding also takes priority over nearly all other garnishments. An employer must honor the order before creditor judgments, student loan garnishments, or any other non-support withholding. The only exception is an IRS tax levy entered before the underlying child support order was issued.11Administration for Children and Families. Income Withholding
Bonuses, Commissions, and Severance
Lump-sum payments are subject to child support withholding, but the rules vary by state. Roughly a third of states require employers to report lump-sum payments to the child support agency before releasing the funds. Reporting thresholds range from $100 to $1,000, and some states require the employer to hold the payment for a waiting period, commonly 14 to 45 days, so the agency can issue a withholding order against the lump sum.
States that require reporting often cap lump-sum withholding at 50% of disposable income, lower than the standard support caps. In states that don’t require reporting, the regular withholding percentages apply to the lump sum as they would to ordinary wages. Before releasing a large bonus or severance check for someone with an active order, check the state’s intergovernmental reference guide or contact the child support agency listed on the order. Get it wrong and the employer owes the difference.
Protections for the Employee
Federal law prohibits firing a worker because their wages are being garnished. A willful violation carries a fine of up to $1,000, up to one year of imprisonment, or both.12Office of the Law Revision Counsel. 15 USC 1674 – Restriction on Discharge From Employment by Reason of Garnishment For child support specifically, federal law goes further: states must impose fines on employers who discharge, refuse to hire, or discipline an employee because of a child support withholding order.6Office of the Law Revision Counsel. 42 USC 666 – Requirement of Statutorily Prescribed Procedures to Improve Effectiveness of Child Support Enforcement The order itself creates a paper trail, which makes retaliation easy to prove.
Employees who believe the order contains errors can contest it, but the grounds are narrow. Challenges are generally limited to mistakes of fact: the amount owed is wrong, the arrears figure is incorrect, or the wrong person was identified as the obligor. An employee who disagrees with the underlying support amount needs to go back to court to modify the support order itself; the employer has no role in that dispute. When an order crosses state lines, the employer must give the employee a copy of it.13Administration for Children and Families. Income Withholding for Support – Instructions
Penalties for Employers Who Don’t Comply
Employers who ignore or mishandle an order face real consequences. The most common penalty is direct liability: the employer becomes responsible for paying the child support amount that should have been withheld but wasn’t.14Administration for Children and Families. Income Withholding Answers for Employers States can impose additional fines on top of that. Dollar amounts vary, but the pattern holds: the employer ends up paying more than if they had simply processed the order correctly.
There is a safe harbor on the other side. An employer that follows a withholding order appearing valid on its face is shielded from civil liability to any individual or agency for acting in compliance.6Office of the Law Revision Counsel. 42 USC 666 – Requirement of Statutorily Prescribed Procedures to Improve Effectiveness of Child Support Enforcement When an employee protests that the underlying order is wrong, the employer’s job is still to comply with what the form says. Sorting out whether the order itself is correct belongs between the employee and the court.
When the Order Can Be Changed or Stopped
An employer cannot stop or adjust withholding based on a request from the employee, a phone call from the custodial parent, or any agreement between the parties. Only a new official document from the court or the issuing child support agency, either an amended order or a termination notice, provides the legal authority to change or stop deductions. Orders commonly end when the child reaches the age of majority (18 in most states, though some extend support obligations to 21 or through college enrollment) or when a court modifies the order based on changed financial circumstances.
When an employee with an active order leaves the company, the employer must report the termination to the child support agency as soon as possible.15Administration for Children and Families. Reporting Employee Terminations – Private Employers and Federal Agencies The notice should include the employee’s last known address and, if available, their new employer. Delay can leave the former employer on the hook for payments that should have been deducted during the gap.
A Note on Independent Contractors
Income withholding is built around W-2 employment, where the employer controls the paycheck. For workers paid on a 1099 basis, enforcement is harder. Automated withholding is largely impractical when payments are irregular, project-based, or routed through accounts payable rather than payroll. Some states require companies to report payments to independent contractors to the child support agency, but reporting is less systematic than for employees. The Consumer Credit Protection Act’s withholding limits were written for employer-employee relationships and don’t provide clear guidance for contractor payments; some states cap contractor withholding at 50% of the payment, while others have no specific statutory limit. Companies that regularly engage contractors should check whether their state requires lump-sum or contractor payment reporting and build that step into accounts payable.
