State Disbursement Unit (SDU)
The California Child Support Automated Payment System will provide
employers a safe and convenient way to submit child support withholding
payments on behalf of their employees. Payments can be made using
electronic funds transfer (EFT) submitted to a single physical location.
The State Disbursement Unit offers multiple methods to remit payments electronically, which
are fast, simple and secure. For EFT/EDI payment processing, please contact
the SDU at 1-866-901-3212.
When a party is receiving child support services offered through a county child support agency,
the case is a IV-D case. A Non-IV-D case in comparison is when the parties are not obtaining
services through a county child support agency and the custodial party or a representative acting
on his or her behalf serves the employer with an income withholding order.
When processing a Non-IV-D Income Withholding Order, the employer should keep the original
withholding form and send a copy to the California State Disbursement Unit (SDU) by eFax to
firstname.lastname@example.org, fax to (916) 576-8881 or mail to the following address:

The SDU will provide a case number by return mail that the employer must include on all
payments for the case.

Some employees may have more than one child support obligation and it is possible for an
employee to have both a IV-D and Non-IV-D obligation, as well as withholding orders from
other states. Employers whose employees have multiple withholding orders are advised to call
(866) 901-3212 for assistance in calculating the amount to withhold.
