Moved from Louisiana to Wyoming Mid-Year: Which State Tax Returns Do You File?
Answer
Louisiana once, and then nothing. Because Wyoming does not tax personal income, this move takes you out of the state income tax system entirely. File the Louisiana part-year return for the pre-move income and make sure Louisiana withholding actually stopped when you left.

The clean part of this move is that only one return follows it. The part that catches people is the withholding: Louisiana tax should stop when your residency does, and it often does not without a prompt.
