Mail it to Austin, Texas.

Please clarify what you mean when you say you are a "resident" of Indiana. The question is: where is your domicile? Meaning where do you spend the most days? If you live and work in TX that that is most likely your domicile. The exception would be if your living in TX is considered by you to be temporary - perhaps a short term job - and you intend to not live in TX for very long. Then the state of IN would argue that you have not really moved out, and therefore you are still a resident of IN and must pay IN income tax. Given that TX has no income tax, you would obviously be better off claiming TX as your domicile. So my advice is buld the case that you are a resident of TX - get yourself a TX driver's license (if you haven't already), and use TX as your primary address. You can continue to visit IN, and even own a home there, no problem.

EDIT - perhaps I misread the question. I thought the OP was asking about how to avoid having to pay Indiana income tax on his wages from his job TX.

Am I missing something? I thought the abberviation TX stands for Texas, not Tennessee?

Typos on my part. The OP says he lives in Texas, so I should have written "TX" consistently.

Ironically the answer I gave would be the same regardless, given that neither TX nor TN have an income tax!
