Even after we efiled 2018 T5 on ProFile successfully, we received the error email notice from CRA:
"We are unable to process your submission because it does not conform to our specifications. We strongly recommend that you validate all submissions with a validating parser before you file. Please validate your file, correct it and then resend your submission."
What am I doing wrong? The ProFile FX file shows it was submitted with the confirmation page.
Thanks,
