I used to work as a vacation work student (FY 14, 15, 16) for 6 weeks each year while studying and I would get taxed on it. I started working this year and have filed my tax return (FY17) and I am awaiting audit so that I can get my refund. My question is can I still file my tax returns for those times that I worked and get my refund back. I didn’t have a tax number then as I was still a student but my income was taxed. I do have the IRP5 forms for those 3 years from the same company I’m working at.
