The following file types can be used as attachments:

  • .pdf

Provided the attachments are transmitted within 24 hours of EFILE of the T2 return, there are no limitations to the number of attachments that can be transmitted.

Can I make attachments prior to the T2 return being transmitted?

Yes, but the T2 return must be transmitted first, before the attachments.
