Electronic Funds Transfer for Wage Attachment Payments

ACH Credit Instructions for Third Party Payments (TPP)

Payroll providers and businesses have the option to send wage attachment payments electronically by ACH credit. Work with your financial institution to use the following ACH format to push these payments to the department.

  1. The ACH Credit must include the TPP banking convention in the addendum record of a NACHA CCD+ transaction. TPP conventions must be followed exactly for proper payment posting. Do not use other addenda banking conventions.

  2. NACHA record formats for CCD+ entries flow in the following order:

    File Header Record ("1" Record)

    • Company/Batch Header Record ("5" Record)
      • Entry Detail Record ("6" Record)
        • Addenda Record (1 addenda with 80 byte Payment Related Information Field, "7" Record)
      • Entry Detail Record ("6" Record)
        • Addenda Record (1 addenda with 80 byte Payment Related Information Field, "7" Record)
      • Entry Detail Record ("6" Record)
        • Addenda Record (1 addenda with 80 byte Payment Related Information Field, "7" Record)

    • Company/Batch Control Record ("8" Record)

    • File Control Record ("9" Record)

  3. To create an ACH Credit file, the Entry Detail Record ("6" Record) must be set up so the ACH Credit transaction file includes:
    • The department's depository bank's ABA (American Bank Association) Routing Transit Number (RTN) in the Receiving Bank Number and Check Digit positions (fields 3 and 4)
      US Bank - Milwaukee's ABA Routing Transit Number (RTN) is 075000022
    • The department's bank account number (field 5)
      Account number for Wage Attachment Payment 12165303215030

  4. A pre-notification transaction (a "zero-dollar" transaction) may be initiated at least 10 business days prior to the first transmission of an actual remittance transfer. These transactions are not acknowledged by US Bank unless a problem occurs.

The following sections contain information on how to use the TPP Conventions within the Payment Related Information Field (field 3) of the NACHA Addenda Record ("7" Record). For more specific information on NACHA formats, specifications, and definitions, refer to the NACHA Operating Rules. Contact NACHA if you need further information.
