Question:
My husband is a pilot based in Tenn.and I'm in Ky.We file Fed.tax together.Can we file state individually.

Answer:
At least for TN purposes, there will not be any state income tax exposure. However, you should determine whether you are legally domiciled in KY before filing - that is, voting rights, driver's license, etc. You may have trouble filing differently for federal purposes vs. state purposes since a state revenue agency may easily reconcile the total taxable income amount on your federal income tax return.
