I need some help here. My son, attending ASU, has worked in both California and Arizona last year. He also has a scholarship that covers more than qualify tuition and fees from ASU. We are not claiming him as our dependent in our tax return. Is he considered to be a part time resident as far as income tax is concern for both states? Or is he still considered to be a California resident and will be taxed on his ASU scholarship and Arizona earnings by California? Are there options for him in how to file his state income tax? Thank you.
