Reminder:

Follow the table/procedures in IRM 3.12.21.7.2.1(5) above to identify the originator (to whom the Form 4227 (and document) should be sent for research and correction).

TC 912 and TC 914 are valid only when both are present and only when they are present an equal number of times.

TC 916 and TC 917 are valid only when both are present and only when they are present an equal number of times.

TC 550, TC 560 and TC 564 are valid only once per document. If TC 550, TC 560 and TC 564 occur more than once in Sections 30 through 33, the duplicate transaction codes will appear invalid.

TC 560 and TC 564 are not valid on the same record. If this occurs all the TC 560 and TC 564 will appear invalid.

TC 550, TC 560, and TC 564 are not valid for IRAF (MFT 29).

Correct as follows:

Compare the document with the register.

Correct any transcription errors.

If the document is correct as transcribed and the data on the input document is incorrect, reject the record with Action Code 3.

Prepare Form 4227 for contact with the originator.

Notate on Form 4227, "data on input document is incorrect" and route to the originator.
