TIN Submission

When submitting the Texas Identification Number (TIN) field via batch, the 11-digit TIN must be based on the appropriate TIN Components:

  • Begins with 1 for a payee’s nine-digit Employer’s Identification Number (EIN), as well as for a partner’s EIN.
  • Begins with 2 for a nine-digit Social Security number (SSN) or Individual Taxpayer Identification Number (ITIN) for:
    • Individuals
    • Sole owners who prefer SSN/ITIN
    • Individual partners of a partnership

    Note: TINS will assign the payee a 7 TIN when a 2 TIN is submitted with an SSN or ITIN. However, the SSN/ITIN submitted for sole owners and partners will remain a 2-based TIN.

  • Begins with 3 if your agency requested a Comptroller-assigned TIN for payments to non-resident aliens/foreign payees.
  • See the Payee Number Matrix for the appropriate prefix (1, 2, 3 or 7) by process or function for batch transactions.
  • Use the Check Digit Calculator or TINS File Layouts and Check Digit Algorithms (login required) as needed.

The Batch T-Codes tell TINS the type of information to process and how to process it. The TIN:

  • Must not already exist for a master account setup (T-Code 600).
  • Must already exist for ownership changes (T-Codes 623 – 627), mail code setup (T-Code 650) or direct deposit setup or changes (T-Codes 660 – 664).
