Annual W-2, W-2C, 1099-R, 1099-MISC, 1099-NEC, 1099-K, and W-2G Electronic Reporting                 Publication 172 

1.   SPECIAL NOTICE 

     Employers and other payers doing business in Wisconsin, must file wage statements and information returns with 
     the Wisconsin Department of Revenue for certain payments made in 2024 (see Publication 117, Guide to Wisconsin 
     Wage Statements and Information Returns). This includes (1) payments made to Wisconsin residents, regardless of 
     where services were performed, and (2) payments made to nonresidents for services performed in Wisconsin. 

     If you file 10 or more wage statements or information returns with the department, you must file electronically. If 
     you file fewer than 10 wage or information returns, we encourage you to file electronically. Electronic filing options 
     include: My Tax Account and Data File Transfer.  

     This publication contains the specifications and instructions for reporting state wages, withholding and information 
     other than wages to the Wisconsin Department of Revenue electronically. 

     For the Data File Transfer, we accept the following files. 

     A. W-2 files in EFW2 Social Security Administration format 
     B. W-2C files in EFW2C Social Security Administration format 
     C. 1099-R, 1099-MISC, 1099-NEC, 1099-K, and W-2G files in Internal Revenue Service format 

     For the Data File Transfer, we do not accept other types of files (for example, PDFs scanned or created with any 
     other software product). We also do not accept: CD-ROMs, cartridges, flash drives, floppy disks, magnetic media, 
     and PDF files created at SSA website. The specifications and record formats in this publication should be used for 
     Tax Year 2024 reporting and for filing prior year, current year and corrected (EFW2, EFW2C, and 1099/W-2G) files. 
     These specifications and record formats are designed to be compatible with the formats in: 

       Social Security Administration Publication No. 42-007, EFW2 Tax Year 2024  Use for W-2 files in EFW2 format. 
        Any reference within this publication to the SSA specification is in italics. Records/files are designed so that 
        copies of the SSA file may be sent to Wisconsin as long as the state information, known as the 'RS' records are 
        included. 

       Social Security Administration Publication No. 42-014, EFW2C Tax Year 2024     Use for W-2C files in EFW2C 
        format. 

       IRS  Publication  1220,  Tax  Year  2024   Use  for  1099-R,  1099-MISC,  1099-NEC,  1099-K,  and  W-2G  files.  All 
        references made to the IRS specifications refer to Publication 1220. 

     Caution: 

        Sections 6, 7, and 8 of this publication refer to the annual reporting of W-2 information to the Wisconsin 
         Department  of  Revenue  and  should  not  be  confused  with  quarterly  wage  reporting  for  unemployment 
         (Department of Workforce Development) purposes. 

        Section 9 of this publication refers to reporting of W-2C information. 

        Sections 10, 11, and 12 of this publication refer to annual 1099-MISC, 1099-NEC, 1099-R, 1099-K, and W-2G 
         reporting. 

        Reciprocity agreements with other states affect W-2 preparation. Wisconsin wage and information reporting 
         requirements are included in Publication 117. See section 11 of Publication 117 for some examples of how to 
         prepare Form W-2.

Annual W-2, W-2C, 1099-R, 1099-MISC, 1099-NEC, 1099-K, and W-2G Electronic Reporting          Publication 172 

2. WHAT'S NEW AND REMINDERS 

   What's New? New Validation Rules for Electronic 1099s. If you are filing Forms 1099 through the data file transfer, the 
     "Payment Year" is a required field on the T, A, and B records. Follow the IRS specifications for these record types 
     in Publication 1220. If you do not provide the payment year on all records, you will receive the following error 
     message: "Payment year is missing from 'X' record." 

   • File Forms W-2C Electronically. You can file Forms W-2C electronically through the data file transfer. 
   • Printable wage and information returns. Effective December 1, 2024, for all tax years, format to print one 
     taxpayer per page. Use the following formats for printable forms: 

     • W-2W-2CW-2G1099-DIV1099-INT1099-MISC1099-NEC1099-R 

   Reminders Truncated Taxpayer Identification Numbers on Forms W-2 and 1099. As a safeguard against identity theft, the 
     IRS allows payers to truncate a payee's taxpayer identification number (SSN, FEIN, or ITIN) on the copy of Form 
     W-2 or 1099 that the payer gives to the payee. The department follows the IRS treatment. 
     Caution: Payers may not truncate the payee's social security number on any forms filed with the department, 
     IRS, or Social Security Administration. Payers may not truncate their own identification number on any forms 
     given to the payee or filed with the department, IRS, or Social Security Administration. 
    W2 record layout clarification: State codes must be included in two different field positions. First, state code 
     positions 3-4 of the RS record. This is the state code where the state income should be reported. Second, state 
     code positions 274-275 of the RS record. This is the state code where the state income tax should be reported. 

    An employer must use the same Wisconsin withholding tax account number (TAN) across all W-2s it files with 
     Wisconsin. 

   • Employers who did not withhold, are not required to withhold, and never held a Wisconsin withholding TAN 
     must use the generic TAN which is 036888888888801. 

   • An employer cannot use the generic TAN if any Wisconsin withholding is reported. 
   • If an employer tries to file wage statements, information returns, Form WT-6, or Form WT-7 via XML using 
     software that has not been approved by the department, a rejection message will be sent: "return not from 
     certified vendor." 
    For payments made in 2024: 
     o Employers filing quarterly, monthly, or semi-monthly cannot submit an annual reconciliation of Wisconsin 
       tax withheld (Form WT-7) until all withholding deposit reports (Form WT-6) have been filed. The filer will

Annual W-2, W-2C, 1099-R, 1099-MISC, 1099-NEC, 1099-K, and W-2G Electronic Reporting         Publication 172 

          get a rejection or error message if (1) the total withholding tax reported on the annual reconciliation is more 
          than the total tax reported on the withholding deposit reports or (2) one or more withholding  deposits 
          have  not  been  filed.  Withholding  deposits  can  be  in  pending  status  with  a  future  payment  date.  This 
          requirement should reduce  the  number  of  penalties  imposed  on  the  annual  reconciliation  and  reduce 
          appeals (see    Wisconsin Tax Bulletin #203). 
        o If you withheld Wisconsin income tax, you must file an annual withholding tax reconciliation (Form WT-7). 
        o Employers and other payers required to file 10 or more W-2s or 10 or more of any one type of information 
          return with the department must file such returns electronically. 
        o All W-2s and information returns required to be filed with the department are due January 31. 
        o Employers may request a 30-day extension for filing W-2s and 1099s with the department if the employers 
          are able to demonstrate good cause and reason for the requested delay. 
        o The  department  may  not  issue  a  refund  to  an  employed  individual  before  March  1,  unless  both  the 
          individual and the individual's employer have filed all required returns and forms with the department. 

3.   FILING TIPS 

     A. Include All of the Following: 

         Wisconsin  withholding  tax  account  number  (TAN). Each  wage  and  information  return  reportable  to 
          Wisconsin must include the employer or payer's Wisconsin withholding TAN (use 036888888888801 if the 
          employer or payer did not withhold Wisconsin tax, was not required to withhold and never held a Wisconsin 
          withholding TAN). 

         Full taxpayer identification number.   Do not truncate the employees' SSNs on Form W-2. A filer may not 
          truncate a payee's identification number on any forms filed with the IRS or with state or local governments. 
          A filer's identification number may not be truncated on any form. 

         "RT" record for W-2 files in EFW2 format. 

         Wisconsin state code is 55  in RS records (EFW2 file) and Payee "B" records (IRS formatted file) that are 
          reportable to Wisconsin. 

         A state code in field position 683-684 of 1099 Payee "B" record. 

     B. Before Filing: 

         Verify  employer/payer  information.   Use  our  account  look-up  to  verify  the  payer's  federal  employer 
          identification number (FEIN), legal name and 15-digit Wisconsin withholding tax number. This information 
          must match our records.  

         Preparers. Use our withholding data exchange to verify your data before sending your file. If your client's 
          FEIN, 15-digit Wisconsin withholding tax number and legal name do not match our records, your file will be 
          rejected.  

         Send a test file first. See below. We issue a 13-digit receipt number for test and non-test files. 

4.   COMMON QUESTIONS 

     A. When are wage and information returns due to the department? 

        Wage statements and information returns have the same due date as the annual reconciliation (Form WT-7), 
        January 31, 2025. See Publication 117 for the most current information.

   B. Is a transmittal letter required with my file? 
      No. Do not include a transmittal letter. 
   C. Is a test file required? 
      No. Sending a test file is not required, however we recommend doing so. Test files using current specifications 
      may be sent through the Data File Transfer webpage. Test files are immediately validated. 
   D. Do I need to request authorization to transfer my file? 
      No. Follow the directions on the Data File Transfer webpage. No password or user ID required. 
   E. What do I name my file? 
      Wisconsin does not have special file naming requirements. 
   F. How will I know the department received my file? 
      You will receive a 13-digit receipt number. If there are errors or problems with your data, your file will be 
      rejected, and you will receive an error message. You will need to correct the error and resubmit your file. 
   G. Do I need to file an annual reconciliation (Form WT-7)? 
      If you withheld Wisconsin income tax, or hold an active Wisconsin withholding tax number, in addition to filing 
      wage  and  information  returns,  you  must  file  an  annual  reconciliation  on  or  by  January  31,  2025.  If  your 
      withholding account is closed prior to December 31, your reconciliation is due to the department within 30 days 
      of the account cease date. 
   H. What information is reflected on the Form WT-7? 
      The annual reconciliation reflects Wisconsin income tax withheld from wages and other payments reportable 
      to Wisconsin. 
      Important  Include on the reconciliation the total number of W-2s reportable to Wisconsin. This includes  
      W-2s mailed to us with "WI" in W-2 box 15 and electronically filed W-2s with "55" in the state code field. Only 
      include information returns (e.g., 1099, W-2G) with Wisconsin withholding on the reconciliation. 
   I. Does Wisconsin participate in Combined Reporting? 
      Currently there is not a Combined Reporting program in place for reporting W-2 information to both the Social 
      Security Administration and Wisconsin Department of Revenue. 
      Persons that file 1099s for Wisconsin payees to the IRS as part of the Combined Federal/State filing program 
      must  file  those  1099s  directly  with  the  Department  of  Revenue  if  Wisconsin  tax  is  withheld.  For  specific 
      Federal/State Combined Reporting requirements, refer to IRS Publication 1220. 

5. ANNUAL RECONCILIATION OF WISCONSIN INCOME TAX WITHHELD                         

   Every employer or other issuer withholding Wisconsin income tax from payments made in 2024 must file an annual 
   reconciliation of Wisconsin income tax withheld (Form WT-7). Electronic filing options include: 

     My Tax Account  Our free online filing and payment system. 

     TeleFile  Enter your annual reconciliation using a touch-tone phone. 

     e-File Transmission  This option is used to transmit the Form WT-7 data in an electronic file over the Internet. 
      It is intended for employers who (1) create an XML document to our specifications or (2) purchase commercial 
      software that provides this service.
