An investment club must file a trust return if it is considered to be a "bona fide" trust. This is the case where:
Partnership
An investment club that does not have a specific status may elect to be treated as a partnership. This makes it easier for members to complete the club's income tax return.
An investment club that makes this election must file the Partnership Information Return (form TP-600-V) instead of the trust return.
For further information, refer to the Guide to Filing the Trust Income Tax Return (TP-646.G-V).
