Should I Use Web File Upload?

Should I Use Web File Upload?

If you previously used CDs to file W-2s and 1099s, switching to Web File Upload is simple. Use this filing option to upload flat files (.txt only) containing your NC-3, W2, and 1099 information.

This option has been enhanced to help payroll providers and other large businesses meet the electronic filing requirement. You are not required to register to use the Web File Upload option. Using this option, you are able to:

  • Upload one file with data for multiple businesses
  • Upload individual files for each business
  • Create files with no file size limitation (some web browsers may have a limit of 2GB per transaction)
