Where can I find an EFile/Netfile log?
Both myTaxExpress Netfile and Efile software have a log file to record the returns filed successfully. The log file for Netfile software is called netfilelog.txt. For Efile software is called efilelog.txt.
For Windows 7+ computers, this log file is stored in a folder like C:\Users\[username]\Documents\mytaxexpress-efile\2021\run for Efile software or C:\Users\[username]\Documents\mytaxexpress\2021\run for Netfile software, using 2021 software as an example.
For Mac OS computers, this log file is stored in a folder like /Users/[username]/Library/Application Support/mytaxexpress_2021e for Efile software or /Users/[username]/Library/Application Support/mytaxexpress_2021n for Netfile software, using 2021 software as an example.
If you are not sure, whether a return is filed or not, you can try to file it again. The CRA system will return a message that the return is already filed.
Here is a screenshot of the log file:
