I don't know a lot about S. Dakota. However, I can expound on FL. Vs NC. We moved! You can establish a domicile in FL. But you must have a permanent address and a FL. Drivers liscense. There are many eloborate questions and documents we had to present but it was not an issue as we purchased property in the state. If using just a PO box as an address its a bit more difficult. There have been many posts on this topic over the years on the forum. A quick search, will I'm sure, bring a lot of information. We pay the same for property tax as NC but no personal income tax, no personal property tax, ie: MH this alone drove us out of NC. There are still ways to establish domicile w/o buying real property but it's been fifteen years since we went sailing and used the PO box residency. Come on down the weathers fine!
