Electronic Funds Transfer Payment Instructions for Financial Institutions for TXP

ACH Credit Instructions

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, field 3) ("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 (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
- For a list of the State's bank account numbers to send your payment to: See tax type information table (Table 5A) for the specific tax type you are paying. The bank account number must include any suffix indicated in that table.
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 TXP 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, (703) 561-1100, if you need further information.

TABLE 2 -- Definitions of TXP Conventions - Data Elements and Separators

Data Elements	Definition
Segment Identifier	Identifies the transfer as a tax payment. It must always be coded as TXP.
Taxpayer Identification Number	This is a number which identifies your company to WDOR. This number may be different for each tax type, and varies in length. See Table 5B.
Tax Type Code	This field is always 5 characters in length. WDOR follows the FTA standardized tax type codes for the first 3 characters. The final two characters are department assigned. See Table 5A.
Tax Period End Date	This date should be reported as the last day of the period or the income year for which the tax is being paid. It is not the due date. See Table 5B.
Amount Type	Indicates the type of payment. T = Tax
Amount	This is the total amount paid, except for withholding tax it is the amount withheld for the period involved. This is a variable length field (right justify). This field must always include cents and have a minimum of 3 digits.
Separator	The separator is used to separate fields within a segment. The character to be used is the asterisk.
Taxpayer Verification	The first six letters of your company name.
Terminator	The segment terminator identifies the end of the free form portion of the addenda record and must always be a back slash.

TABLE 3 -- Definitions of TXP Conventions - Field Requirements

Field Requirements	Definition
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 Types	Definition
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.
