I am completing a 3 month internship in Idaho, but will return to California upon completion. What is the best way to file taxes? Idaho’s state taxes are actually higher than Cali, so I would like to avoid them. Someone else mentioned they are just having their taxes withheld by their originating state, Is this possible? Of course, I would like to have the least taxes taken out, so if there is anyway I can pay only California taxes on the money I would love to know how?
