Yes, if you went to Oregon to work you will have to file an Oregon state tax return if required. If it was just a temporary stay for work (you did not move), you will file as an Oregon nonresident. If you were a full year Arizona resident, you must also report the income on your Arizona tax return, but you will also get a credit for the amount you paid to Oregon so that you are not double taxed. Turbo Tax will guide you through the process, but if you have questions, please post them here!
