Hi Travis, I think you T4 comes from where ever you work at, contact your employer to get your T4.
You can pick up tax forms at your local post office, these are the forms that you fill in and use the information from your T4.
You can also do it on-line with a program.
I hope this helps!
Lots of people file late, not my style but many do. Services cost you money. There may be assistance available through your group home. Good luck!
You are welcome Travis, glad I could help. I am waving at you from the Alberta prairies, just one province away!
