[SIZE=+1]I retired in 2005. Later that year, I moved from NY to a friend's home in AZ. [/SIZE][SIZE=+1][SIZE=+1][SIZE=+1]While there, [/SIZE]I transferred my car's title, got an AZ driver license, registered to vote, even opened a few local bank accounts. [/SIZE]Several months [/SIZE][SIZE=+1][SIZE=+1][SIZE=+1][SIZE=+1]later, [/SIZE][/SIZE]I decided to move to Thailand where I stayed for over 10 years.[/SIZE] I continue to use my friend's home for my storage and my official US address. [/SIZE][SIZE=+1]I have voted [/SIZE][SIZE=+1][SIZE=+1]via overseas absentee ballot [/SIZE]for [/SIZE][SIZE=+1][SIZE=+1]only N[/SIZE]ational candidates not local ones. During my only visit back to the states 3 years ago, I renewed my expired AZ driver license. In all that time, I never filed for a state income tax since I considered myself a Thai resident and used my Thai address on my 1040. I never got any tax notices from either NY, my working home for 35 years or AZ so I am wondering, how does a state know if you are living in their state, especially if you are retired and not earning any local income other than possible bank interest?[/SIZE]
