If you do federal joint return, state you need to do joint return, use turbotax premium, follow the instruction, They will give you credit for the tax you paid on other state, they will prorate different sate,

既然都联合报了联邦税
州税就得联合报
一般来说会按照part year residence来给你折扣
不过这个都要看州的说明，每个州细则不一样，例如有人说过有些州如果配偶是full-year resident就得一起full year resident啥的，联合报要亏一些州税（这一点我没有考证）

可以的。
