Changes to the IWO Form

On October 4, 2016, a notice for public comment on the revised Income Withholding for Support (IWO) form was posted to the Federal Register on pages 68421-68422, Volume 81, Number 192 Visit disclaimer page . The IWO form and instructions were updated for clarity and consistency. Key changes include:

  • Added an optional field for the employee/obligor’s date of birth
  • Clarified that an entity, including a child support agency, should send a One-Time Order/Notice for Lump Sum Payment after receiving notification of an upcoming lump sum payment by an employer or other source
  • Removed the words “up to” in front of the withholding limit percentage and clarified that the IWO sender must enter a specific withholding percentage, up to the Consumer Credit Protection Act (CCPA) limits, in the correct data field to avoid overwithholding from a noncustodial parent
  • Clarified tribal withholding limits and added links to addresses and contacts for tribes
  • Changed references to FIPS Code to Locator Code
  • Added a link to the OCSE Child Support Portal for employers to report lump sum payments and terminations and to update information about their company

  • Added a statement on encryption requirements

Statutory requirements under sections 466(a)(1), (a)(8), and 466(b)(6) Visit disclaimer page of the Act require the use of the Income Withholding for Support (IWO) form in all IV-D cases, and in non-IV-D cases with orders initially issued in the state on or after January 1, 1994. The interim final rule issued on February 9, 1999 [Volume 64, Number 26 on page 6237 Visit disclaimer page ], implemented section 466(b)(6)(A)(ii) Visit disclaimer page of the Act requiring the use of the OMB-approved IWO form (OMB 0970-0154) [see 45 CFR 303.100(e)(1) Visit disclaimer page ]. Private firms, attorneys, and courts authorized under state law to issue IWOs must use the OMB-approved IWO form for all child support income withholding by employers. We urge states to review their income withholding procedures and state plan preprint pages 2.12-1, 2.12-8, and 2.12-8B to ensure compliance with the income withholding requirements.
