As an out-of-state college student earning income, should my current mailing address be my permanent address or the address my packages go to right now?

When filing your taxes, use your home address in your home state.  You are not considered a resident of your college state.  You are considered ''temporarily away'' from your home state if you intend on returning after college.  Since you are earning some income while in your temporary state, you will file a non-resident income tax return for your college state and a resident tax return for your home state.  After completing your federal return, TurboTax will walk you through your state returns.  Prepare your college state return before your home state return so credits are applied properly.  

Enter home state address in TurboTax and indicate that your earned money in your college state and the program will generate the correct state returns and forms you need.
