Should I file state taxes in both Penn and Cali if I am a full-time college student in Penn but interned for 3 months in Cali.?
My daughter goes to college full time in Pennsylvania and interned for 3 months in California during 2015. California withheld state taxes from her pay checks over the 3 month period. She is claimed as a dependent on my (her Dad) taxes. She is filing her taxes (single) and needs to know if she should file both PA and CA state taxes. Will she be double-taxed? Or, can she get a credit in one of the states so she doesn't have to pay both state taxes on the same income? Thank you for your advice.
