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,Data File Transfer, and secure file transfer protocol (sFTP). 

     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 as shown in IRS 
        Publication 1220. 

     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. 

     For sFTP, we accept the following files:  

     A. 1099-R, 1099-MISC, 1099-NEC, 1099-K, and W-2G files in the eStandards format 

     B. W-2G and 1099s in the IRIS format 

             IRS Publication 5718 – Use for all information returns. See the publication for a list of all form types 
              accepted in IRIS format. 

     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.

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

    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. 

     Questions? Contact us at (608) 266-2776 or DORW2DataQuestions@wisconsin.gov. 

2. WHAT'S NEW AND REMINDERS 

   What's New? Supporting new IRIS schemas. For tax years 2024 forward, we will support the IRS Information Returns Intake 
     System (IRIS) schemas.  
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 formats for printable forms as specified in IRS Publications1141,1167, and1179.  

   Reminders 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." 

   • 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 
                                                       
                                                      4

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? 
      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.

     Caution: 

       We do not support electronic filing of PDF versions of the Form WT-7. 

       Do not use 03688888888801 for filing the annual reconciliation (Form WT-7.)  Employers who withheld tax for 
        one or more of their employees are required to have their own Wisconsin withholding tax account.  

       Employers who were not required to withhold (and did not withhold) Wisconsin income tax from payments 
        made in 2024 should not file an annual reconciliation (Form WT-7) if they did not have an active Wisconsin 
        withholding tax account for any part of 2024. To inactivate your Wisconsin withholding tax account, please 
        contact us at (608) 266-2776.

7.   COMMON ERRORS WHEN REPORTING W-2 DATA IN EFW2 FORMAT 

     To avoid some of the common errors that may cause your file to be rejected, please verify:Your FEIN, 15-digit Wisconsin withholding tax number, and legal name. They must match our records.A generic Wisconsin tax number 036888888888801 cannot be used if Wisconsin withholding is reported.Employee social security number, name, and address, including ZIP code, are in the proper format for each 
        employee in both the RW and RS record files.Tax year is correct (reflects the year in which payments were made). The tax year is found on the "RE" record.Record lengths are 512 bytes long. Watch for extra carriage return or line feed characters at the end of the 
        report.All money amounts are dollar and cents and should be right justified and zero filled. No negative amounts or 
        special characters.The state codes in positions 3 and 274 in the "RS" record are both required fields. Position 3 must include the 
        state code where state income should be reported. Position 274 must include the state code where the state 
        income tax withheld should be reported.

13. IRIS BUSINESS RULES FOR TAX YEAR 2024 

    The Wisconsin Department of Revenue is now accepting data using IRIS schemas. Many of the rules for IRIS schemas 
    overlap with rules in place for the e-Standards 1099 schemas. The e-Standards files begin with INF, hence the "INF" 
    prefix. We are introducing four new rules for IRIS schemas. These new rules begin with "IRIS" and are highlighted 
    for your convenience.
