State tax filing

To explain it differently: For non-residents and part-year residents, New York first calculates your tax as if you were a full-year resident of New York.  It then divides your New York income by your total income to obtain a percentage.  It then applies that percentage to the full-year calculated tax to determine the tax due to NY.
