I work in CO and have a W2 I file CO taxes.

I have farm income in MT.  It looks like MT taxes me for my income I have aready paid taxes for in CO because MT shows my agjusted gross income as that from CO.

You report all your income on your Resident Return.  

You will be asked in the State Interview if you 'paid taxes to another state' and get credit for tax you paid to another state.

Prepare your Non-Resident State Return first, then your Resident State.
