I have had some unanswered questions regarding that life style.
Most States seen to require a 6 mo per year residency to be a citizen of same.
Is it possible to be a US citizen, but not a State (/territory) citizen?
Can you get a US driver's license rather than a State issued one?
What about voting, state taxes, "permanent address", etc.?
Yes, my understanding is the 183-day rule for IRS and state income tax purposes (if applicable). If you live inside or outside of a state for 183 days in the calendar year (tax year for ordinary taxpayers on a cash accounting basis), this standard will be used to determine your tax home.
For voting and driver license purposes, the 183-day rule does not apply. Most states will consider you a full-time resident after so many days of continuous residency and expect you to get a driver license. Voter registration may be part of the “”motor voter” process.
I have a single driver license, but multiple vehicles registered, titled and insured in the states where locally stored/used. Sadly, you have to get separate auto insurance policies if you go this route (thousands of miles apart).
I vote in a single state which is my tax state. I hope to change over time to a more favorable environment. My jury duty obligation is tied to my driver license as that is the test used by court officials.
