What this does not answer
State income tax only. Property tax, sales tax and housing costs usually matter more to a moving decision than the figures on this page, and none of them is here.
A full year in each state. In the year you move you will normally file part-year returns in both, splitting the income between them, so neither column is what you will actually pay that year.
