I'm trying to claim the MB Tuition fee income rebate but under "what year did you graduate" 2017 is not coming up. How can I fix this issue? Can I not claim it?

Thank you for notifying us of this issue. We have put in the fix for this and it will be out in our next release (Apr 12).

In the meantime, you can use the forms mode and Navigate to form T1005 and directly input the year in Part 1.
