On April 24, the CRA issued a communication to some Canadians that referred to an incorrect filing deadline for 2014 tax returns of May 5, 2015, rather than April 30, 2015.
The CRA takes full responsibility for the error. As a result, 2014 tax returns filed by midnight on May 5, 2015, will not incur interest or penalties.
