Retirement tax questions

Thanks for the response, here are the details:

  • Did you maintain a dwelling in GA for the whole year?
    • I had an address in GA but during the time I was in WA, I had sublet my apartment to someone.
  • Did you intend to go back to GA when you went to WA?
    • Yes, I intended to return.
  • Did you establish residence in WA?
    • Not sure what this means - I lived there for 3 months, was interning at a company, made bulk of my income for the year over there, and was living there only.
