When filing my teenagers first form, it asks to check her Notice of Assessment. What do I do if she doesn't have a Notice of Assessment? Can I ignore?

What is it asking for on the NOA? Tuition amounts? RRSP contribution limit?

Nothing like that since she's just a 16yr old. Just income and basic personal info.

If it's asking about something like tuition on the NOA, then you can ignore it. But sometimes the information is required.
