Deductions & credits

Sorry,  I don't have a list but of course it doesn't include states that either don't have income tax at all and states.  States that have a flat tax rate independent of income will basically end up calculating the same tax whether or not they start with the federal income.  (There could well be some differences if the state offers a standard deduction or exemption credits that have to be apportioned between states.)  You'd want to go to the income tax site of a state in question and look at the part-year resident form and instructions to see how they go about the calculation.
