No. As explained by Champ @TomD8 your son will not pay MI tax. He will file a non-resident return for MI but indicate that NONE of the income was earned or received in MI. MI will refund the tax withheld. Your son will owe tax to CA. He needs to prepare the NON-resident MI return first before he prepares the CA return. Do not mess around and change anything that you see on the W-2.
