Income Withholding Order (IWO)

1. What is an IWO? What is an Order to Withhold Income for Child Support?

The Income Withholding for Support form, also called an IWO, is a court order served on employers which requires them to withhold an employee’s wages for payment of child support. This form is also called a wage assignment or garnishment order.

2. How will I receive the Income Withholding Order for Support?

The Income Withholding Order for Support is served to employers either as a hard copy or electronically. To receive the form electronically, register for the Electronic Income Withholding (e-IWO) process. To learn more about e-IWOs, see the e-IWO FAQs on this page or download the e-IWO Factsheet.

3. Now that I’ve gotten an IWO, what am I supposed to do?

Read it carefully and follow its instructions. You may need to send a copy to the California State Disbursement Unit (physical address, fax, & email below), if your IWO was issued by an attorney or other private party.

You do not need to send a copy if your IWO came from any of the following:

4. Why does the state need a copy of the IWO on my employee?

This document provides the necessary information that enables the California State Disbursement Unit (SDU) to open a case and ensure payments are processed accurately. All states are under a federal mandate to create a single, statewide case registry of all child support orders and to centralize payment processing. The SDU is that single entity for child support cases in California.

5. Will I need to send a copy of the IWO with each payment?

No. You only need to send a copy when there is a change or you receive a new Income Withholding for Support from an attorney or other private party.

6. The Income Withholding for Support doesn’t have a judge’s signature. Do I still have to comply with it?

Yes. The Income Withholding for Support is a federally required form and is used in all support cases in all states. The signature of a judicial officer is not required when the order is sent by a child support agency. If the order is not from an agency you should still consider it valid and send a copy to the California State Disbursement Unit (SDU).

7. Does this mean my employee hasn’t been paying their child support?

No. An IWO is issued whenever a child support case is established and the parent with higher earnings or less custody is employed. It is rare for a parent who is employed to be allowed to pay through other means. Employers should not use an Income Withholding for Support as grounds for refusing to hire a person or for taking disciplinary action against an employee, and you could face civil penalties if you do.

8. If an Income Withholding for Support is from another state, must the payment be sent to that state?

Yes. You must comply with income withholding orders from other states. Instructions on the income withholding order will specify where to mail the payment. Please do not send payments ordered by other states to the California State Disbursement Unit.

9. What if the name and/or Social Security number on the Income Withholding for Support don’t match my employee?

Call California Child Support at 1-866-901-3212 to find out if there is an error in the number or name, or if this could be a case of mistaken identity.

10. My employee has a Non 4-D case. What is Non 4-D?

Cases managed by child support agencies in any state are called “4-D” cases, referring to Title IV-D of the Federal Social Security Act, the law that created Child Support Services agencies. These Income Withholding Orders are issued by the child support agency and do not require a judge’s signature.

11. Some of my employees only work part time. What do I do if 50% of their net disposable earnings is less than the withholding amount for the pay period?

California law requires that you only withhold up to 50% of your employee’s net disposable earning each month (this withholding limit varies from state to state). If your employee voluntarily agrees to pay more, he or she should first contact the court or if they have an open case with a local child support agency, that office will work with the employee to make arrangements to pay more.

12. What do I do if an employee has other non-support income attachments?

Except when an IRS tax lien was served prior to the date the child support order was entered, federal and state laws require child support withholding to take priority over all other income attachments. You must withhold the required amount as long as the amount does not exceed 50% of the employee’s net disposable earnings. An Order/Notice for child support has priority against any attachment, execution or other assignment.

13. Can an Income Withholding Order be terminated over the telephone?

No, an IWO form must be used for IWO termination.

Electronic Income Withholding Order (e-IWO)

1. What is an Electronic Income Withholding Order (e-IWO)?

The electronic Income Withholding Order (e-IWO) is a cost-effective way for employers to receive the Income Withholding Order. Although the e-IWO does not provide electronic payment features, there are additional benefits, such as:

2. How does an e-IWO benefit my company?

3. Can I use e-IWO to report lump sums and terminations?

Yes. Employers can use e-IWO to submit notification of employee terminations and lump sum payments electronically.

4. What are the available implementation options?

There are three options available:

  1. e-IWO Online: The e-IWO Online is best suited for smaller employers that do not have an internal server, or IT resources. Once registered, the e-IWO will be available for employers to download from the federal Office of Child Support Services Child Support Portal. The e-IWOs must be downloaded and acknowledged by the employer within 3 business days. The estimated implementation of e-IWO Online is 5 to 15 business days.
  2. No Programing Option: The No-Programming Option is also available for smaller employers, but it requires IT resources for configuring of server and directories. Employers will receive a PDF or Excel document to acknowledge or reject the Income Withholding Order. The format you choose will determine how your company exchanges information with the Child Support Enforcement computer program. The estimated implementation of the No Programming Option is 2 to 4 weeks.
  3. System-to-System Interface: The System-to-System Interface Option is suited for employers that receive a high volume of IWOs and have the technological resources to support connectivity. Employers process the electronic records and make the appropriate updates to the payroll system based on the IWO. This option is customized based on your company’s needs and software capabilities. This option is recommended for midsize companies and large size corporations with IT resources that can commit to several months of programming. The estimated implementation of the System-to-System Interface is 3 to 5 months.

5. What if our company has limited resources to help implement e-IWO?

If your company has limited resources, e-IWO Online is the best choice. With e-IWO Online, employers can register on the federal Office of Child Support Services (OCSS), Child Support Portal as a new user. Employers will begin receiving the e-IWO in 5-15 business days. To register as a New User and enroll in e-IWO Online, visit the OCSS Child Support Portal.
