The ``agent`` said this was a question for tex experts and hung up. I`m pretty sure it is that I do not know how the program here handles these things. If doing a joint return, do I fill this on on both persons returns, or is 50% split indication at the bottom ok? I found this, but I have no idea if it is correct due to the 'agent' I spoke with briefly...... If you're reporting a capital gain from a T-slip (T3, T5, T5008, etc.), enter the full amount in the boxes as per your slip, and enter your percentage at the bottom of the slip. Your spouse’s return should also report the full amount from the slip, and their own percentage.
