As of April 20, 2020 the Canada Revenu Agency (CRA) will allow the transmission of a return even if it has already been mailed to CRA on paper, as long as it has not yet been processed.
The Canada Revenue Agency (CRA) has investigated EFILE error 92271 and has determined a change made in early May cause certain returns that were previously accepted to now be rejected.
The CRA will continue to recognize a T183 and T183CORP that contains an electronic signature as having met the signature requirements of the ITA as a temporary administrative measure for the remainder of the filing season.
