Additional Notes for W-2 Electronic Filing

  • We highly recommend you test your W-2 file in the AccuWage Online tab before submitting your file to the SSA to check for any errors. 
  • To submit your file to the SSA, the file will need to be renamed before submitting. Your file will be called W2REPORT_2023.FED. Right-click and replace FED with txt. It should not be necessary to zip the file.
  • There has been some confusion about the User ID and whether it is required. Even though the BSO has changed the login procedure, the User ID is still required according to the W-2 electronic filing specifications for 2023.
