I hear a lot of ex-pats who move to a non-income-tax state (like Texas) just before they move overseas. If your US residence is still in a state with income tax, even though you don't live there you still get taxed on your overseas income because as a US citizen you still have residence in your state even if you don't live there. It doesn't matter if you're physically there or not.
The only other alternative is to renounce your US citizenship if you never plan on coming back.
