Why am I getting IRS error code R0000-901-01?


IRS error code R0000-901-01, Filer's EIN and Name Control in the Return Header, must match data in the e-File database.

  • Check the name control in Screen ELF. If you are forcing the name control in Screen ELF, verify in Publication 4163 that you have the correct name control.
  • Verify that you have the correct Employer Identification Number (EIN) entered in the File > Client Properties dialog.

If you are not forcing the name control and the EIN is correct, then you need to call the IRS Ogden Help Desk at 866-255-0654 and have them verify the client's EIN.
