Hi,
I was a resident of texas full time in 2008 with all income from texas. my wife was in texas till sept. 2008 with no income and from sept.-dec. she was in michigan with income. We have filed joint for federal taxes. For Michigan State, we will file joint but have the following qs:

1. Do I attach a copy of MY (texas resident full time) W2 state filing copy with the Michigan state tax since we are filing joint for michigan state tax.

2. Do we attach a copy of our federal tax return with Michigan state tax return?

Thanks

1) Yes.

2) Not required, but not a bad idea.
