.05 If an LOA is approved, the Service will send the following:

(1) for an Electronic Filer, a notification of approval that will contain the userid/password, and information and procedures regarding signing onto the system for filing electronic Forms 941; and

(2) for an Authorized Signatory, a PIN that may be used only by the Authorized Signatory named in the LOA.

.06 Upon receipt of the document(s) referenced in section 6.05 of this revenue procedure, the Electronic Filer must return the following documents to the Service:

(1) an acknowledgment signed by each employee recipient of the userid/ password indicating possession of, and responsibility for, the userid/password; and

(2) where applicable, an acknowledgment signed by the Authorized Signatory indicating possession of, and responsibility for, the proper use of the PIN for signing tax returns (pursuant to § 301.6061–1) filed in the Form 941 e-file Program. See Publication 1855 for a sample userid/ password and PIN receipt.

.07 Upon receipt of the PIN referenced in section 6.05(2) of this revenue procedure, the On-Line Filer must return an acknowledgment signed by the Authorized Signatory indicating possession of, and responsibility for, the proper use of the PIN for signing tax returns (pursuant to § 301.6061–1) filed in the Form 941 e-file Program.

941 is filed on or before the due date of the return. The due dates prescribed for filing paper Forms 941 with the Service also apply to returns filed under the Form 941 e-file Program. Forms 941 are due on or before the last day of the first calendar month following the period for which the return is made. However, a return for which all tax deposits were made when due for the quarter may be filed by the 10th day of the month following the due date.

.02 An Electronic Filer that is a Transmitter must ensure that an electronic Form 941 is transmitted to the Service by the later of: (1) three days after receipt of the return; or (2) the due date of the return without regard to extensions.

.03 An electronically filed Form 941 is not considered filed until it has been acknowledged as accepted for processing by the Service. If an electronically filed Form 941 is transmitted to the Service on or before the return due date, the return will be deemed timely filed. If an electronically filed Form 941 is initially transmitted to the Service on or before the return due date and is ultimately rejected, but the Electronic Filer complies with section 7.04 or 7.05 of this revenue procedure, as appropriate, and the On-Line Filer complies with section 7.06 of this revenue procedure, the return will be deemed timely filed.

.04 An electronic transmission that causes a Processing Interruption may not be accepted. An Electronic Filer that is an Agent will be asked to resubmit the return(s). If the electronic transmission is acknowledged as rejected by the Service, the Agent should correct the error(s) and retransmit the return(s) on the same calendar day. If the Agent chooses not to have the previously rejected return retransmitted, or if the return still cannot be accepted for processing, a paper Form 941 (or a Form 941 on magnetic tape if the Electronic Filer meets the requirements of Rev. Proc. 96–18) must be filed by the later of: (1) the due date of the return; or (2) within five calendar days of the rejection or notice that the return cannot be retransmitted, with an explanation of why the return is being filed after the due date. For the penalty for failure to file a timely return, see section 17 of this revenue procedure.

ter, and the Transmitter cannot promptly correct any transmission error that causes an electronic transmission to be rejected, then the Transmitter, within 24 hours of receiving the rejection, must take reasonable steps to inform the On-Line Filer that the return has not been filed. When the Transmitter advises the On-Line Filer that the return has not been filed, the Transmitter must provide the On-Line Filer with the reject code(s), an explanation of the reject code(s), and the sequence number of each reject code(s). See Publication 1855 for an explanation of the reject codes.

.06 If the On-Line Filer chooses not to have the electronic portion of the return corrected and transmitted to the Service, or if the electronic portion of the return cannot be accepted for processing by the Service, the On-Line Filer must file a paper Form 941 by the later of: (1) the due date of the return; or (2) within five calendar days of the rejection or notice that the return cannot be retransmitted, with an explanation of why the return is being filed after the due date. For the penalty for failure to file a timely return, see section 17 of this revenue procedure.
