I live in WV and will be moving to TN this year. If I make a 401K withdraw after I move to TN, I am assuming I will not have to pay WV income tax on that withdraw?

WV tax for IT-140 states if you moved into or out of WV file Non-resident. If I live in WV for 9mo of the year, move to TN and then make a 401K withdraw, is that income still exempt from WV State Tax?
