When completing a T2 amended return, the following error may appear in the auditor:
T2 RSI #0000001: The corporation has indicated that this is an amended return in line 200997. The CRA requires that amended returns are not Internet Filed. Instead, print a copy of the amended return barcode and paper file it.
This error appears because amended returns cannot be EFILED unless the return has a January 1st, 2012 year start or later.
