INCOME WITHHOLDING FOR SUPPORT - Instructions
The Income Withholding for Support (IWO) is the OMB-approved form used for income withholding in:
Tribal, intrastate, and interstate cases enforced under Title IV-D of the Social Security Act
All child support orders initially issued in the state on or after January 1, 1994
All child support orders initially issued (or modified) in the state before January 1, 1994, if arrearages occur
This form is the standard format prescribed by the Secretary in accordance with section 466(b)(6)(a)(ii) of the Social Security Act. Except as noted, the following information is required and must be included.
For the purpose of this IWO form and these instructions, “state” is defined as a state or territory.
Dos and don’ts on using this form are found at www.acf.hhs.gov/css/resource/using-the-income- withholding-for-support-form-dos-and-donts.
Sender Information: (Completed by the Sender) Check one box for fields 1a – 1d.
1a. Income Withholding Order/Notice for Support (IWO). Check the box if this is an initial IWO.
1b. Amended IWO. Check the box to indicate that this form amends a previous IWO. Any changes to an IWO must be done through an amended IWO.
1c. One-Time Order/Notice For Lump Sum Payment. Check the box when this IWO is to attach a one- time collection of a lump sum payment after receiving notification from an employer/income withholder or other source. When this box is checked, enter the amount in field 14, Lump Sum Payment, in the Amounts to Withhold section. Additional IWOs must be issued to collect subsequent lump sum payments.
1d. Termination of IWO. Check the box to stop income withholding on a child support order. Complete all applicable identifying information to aid the employer/income withholder in terminating the correct IWO.
The OMB expiration date is printed on the IWO form.
However, the IWO sent on a case does not expire on the OMB expiration date—once the IWO has been sent to the employer, then the IWO is in effect until it is terminated by the Issuing Agency.
The Issuing Agency must make any system updates to implement the currently approved IWO form as soon as possible. In the interim, OMB extended the expiration date of the previously approved form to allow child support agencies to issue an IWO until programming for the currently approved form is complete.
1e. Date. Date this form is completed and/or signed.
1f. Child Support Agency (CSA), Court, Attorney, Private Individual/Entity (Check one box). Check the appropriate box to indicate which entity is sending the IWO. If this IWO is not completed by a state or tribal CSA, the sender should contact the CSA (see www.acf.hhs.gov/programs/css/resource/state-income-withholding-contacts-and-program-requirements) to determine if the CSA needs a copy of this form to facilitate payment processing.
NOTE TO EMPLOYER/INCOME WITHHOLDER: This IWO must be regular on its face. The IWO must be rejected and returned to sender under the following circumstances:
IWO instructs the employer/income withholder to send a payment to an entity other than a state disbursement unit (for example, payable to the custodial party, court, or attorney). Each state is required to operate a state disbursement unit (SDU), which is a centralized facility for collection and disbursement of child support payments. Exception: If this IWO is issued by a court, attorney, or private individual/entity and the initial child support order was entered before January 1, 1994, or the order was issued by a tribal CSA, the employer/income withholder must follow the payment instructions on the form.
After processing an IWO, the payment is returned to income withholder because the order information is not on the child support system and the SDU could not process the payment. The income withholder should return the payment to employee.
Form does not contain all information necessary for the employer to comply with the withholding such as, missing Remittance Identifier, invalid case identifier or missing sender contact information.
Form is altered or contains invalid information such as “step-down” provisions or other future events that an employer is not required to monitor.
Amount to withhold is not a dollar amount.
Sender has not used the OMB-approved form for the IWO.
A copy of the underlying order is required and not included. If you receive this document from an attorney or private individual/entity, a copy of the underlying support order containing a provision authorizing income withholding must be attached.
1g. State/Tribe/Territory. Name of state or tribe sending this form. This must be a government entity of the state or a tribal organization authorized by a tribal government to operate a child support program. If you are a tribe submitting this form on behalf of another tribe, complete field 1i.
1h. Remittance ID (include w/payment). Identifier for the SDU/Tribal Payee designated in the Remittance Information section, field 22, that the employers/income withholders must include when sending payments for this IWO. The Remittance ID is entered as the case identifier on the electronic funds transfer/electronic data interchange (EFT/EDI) record.
NOTE TO EMPLOYER/INCOME
WITHHOLDER: The employer/income withholder must use
the Remittance ID when remitting payments so the SDU or tribe
can identify and apply the payment
correctly. The
Remittance ID
is entered as the
case identifier
on the EFT/EDI
record.
1i. City/County/Dist./Tribe. Optional field for the name of the city, county, or district sending this form. If entered, this must be a government entity of the state or the name of the tribe authorized by a tribal government to operate a child support program for which this form is being sent. If a tribe is submitting this form on behalf of another tribe, enter the name of that tribe.
1j. Order ID. Optional unique identifier associated with a specific child support obligation. It could be a court case number, docket number, or other identifier designated by the sender.
1k. Private Individual/Entity. Name of the private individual/entity or non-IV-D tribal child support organization sending this form.
1l. Case ID. Unique identifier assigned to a state or tribal CSA case. In a state IV-D case as defined at 45 Code of Federal Regulations (CFR) 305.1, this is the identifier reported to the Federal Case Registry (FCR). One IWO must be issued for each IV-D case and must use the unique CSA Case ID. For tribes, this would be either the FCR identifier or other applicable identifier.

and divide that result by the
number of pay periods in a year. Additional information about this
topic is available in Action

NOTE TO EMPLOYER/INCOME WITHHOLDER: The employer/income withholder may not withhold more than the lesser of: 1) the amounts allowed by the Federal Consumer Credit Protection Act [15 USC
§1673(b)]; or 2) the amounts allowed by the jurisdiction of the employee/obligor’s principal place of employment (i.e., the amounts allowed by state law if the employee/obligor’s principal place of employment is in a state; or the amounts allowed by tribal law if the employee/obligor’s principal place of employment is under tribal jurisdiction).
If permitted by the state or tribe, you may deduct a fee for administrative costs. The combined support amount and fee may not exceed the limit on the IWO.
State-specific withholding limitations, time requirements, and any allowable employer fees are available at www.acf.hhs.gov/css/resource/state-income-withholding-contacts-and-program-requirements. For tribe- specific contacts, payment addresses, and withholding limitations, please contact the tribe at www.acf.hhs.gov/sites/default/files/programs/css/tribal_agency_contacts_printable_pdf.pdf or https://www.bia.gov/tribalmap/DataDotGovSamples/tld_map.html.
Depending on applicable state or tribal law, you may need to consider amounts paid for health care premiums to determine disposable income and apply appropriate withholding limits.
A federal government agency may withhold from a variety of incomes and forms of payment, including voluntary separation incentive payments (buy-out payments), incentive pay, and cash awards. For a more complete list, see 5 CFR 581.103.
