State tax filing

If you worked in one state and lived in another, you will need to file a Non-resident return for the state where you worked and a Resident return for the state where you live.  Some states, e.g. Florida, Nevada, Texas, Washington, do not have a state tax, in which case you will only file a return for the state that has a tax.

Don't worry - you'll only pay taxes on your state earnings to one state.  Your Resident state must offer you a credit for the taxes you pay to other states. 

Remember to let TurboTax know you worked in other states - edit "My Info" in your Federal online return - and to complete your Non-resident return before beginning your Resident return, in order to properly calculate the credit your home state owes you.
