ACH Credit Instructions for Financial Institutions

Financial institutions should use the following ACH format for credit payments.

The ACH Credit must include the tax payment (TXP) banking convention within the addendum record of a NACHA CCD+ transaction.  The TXP conventions must be followed exactly for proper posting of payment.  Other addenda banking conventions should not be used.

NACHA records for CCD+ entries must appear in the following sequence:

  • File Header Record ("1" Record)
  • Company/Batch Header Record ("5" Record)
  • Entry Detail Record ("6" Record)
  • Addenda Record (Carries an 80 character free form field) ("7" Record)
  • Company/Batch Control Record ("8" Record)
  • File Control Record ("9" Record)

To create an ACH file, the Entry Detail Record ("6" Record) must be set up for the ACH Credit transaction file to include:

  • The State's depository bank's ABA (American Bank Association) Routing Transit Number in the Receiving Bank Number and Check Digit positions
  • US Bank - Milwaukee's ABA Routing Transit Number is 075000022
  • The Unemployment Insurance ACH Credit Bank Account number is 182845580

The following sections contain information on how to use the TXP Conventions within the Payment Related Information Field 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 (703-561-1100) if you need further information.

TABLE 3 -- Definitions of TXP Conventions - Field Requirements

Indicator Field Requirements
M - Mandatory This field must appear in the TXP convention.
C - Conditional The presence of this field is dependent on the value or presence of other fields in the convention.
O - Optional The appearance of this field is the option of the sending party.

TABLE 4 -- Definitions of TXP Conventions - Data Element Types

Data Element Type
AN (Alpha-Numeric) A sequence of letters, digits, spaces, and/or special characters. The contents shall be left justified. Trailing spaces should be suppressed.
DT (Date) Format for the Date Type is YYMMDD. YY is the last two digits of the year (00-99), MM is the numeric value of the month (01-12), and DD is the numeric value of the day (01-31).
ID (Identifier) An identifier shall always contain a value from a predefined list of values (T = Tax).
N2 (Numeric) N indicates numeric and 2 indicates the decimal places to the right of a fixed, implied decimal point. The decimal point is not transmitted. It is intended that this number will always be positive for the TXP application. In the TXP convention the amount fields are defined as N2 type data elements. Thus, $1200.00 would appear as *120000*. The minimum number of digits for this data element is 3, so $0.01 would appear as *001*.
