Wyoming has no state income tax. My mom is in a similar situation - she bought a home with my dad in Arkansas, but works in Tennessee. Given her income, it was significantly cheaper for her to lease an apartment outside Memphis and live there four days per week than it would have been for her to establish Arkansas residency and pay our income taxes. She typically spends 4-5 days per week in Memphis, and flies back and forth between there and Arkansas - so this makes sense even considering the cost of traveling. I wouldn't consider my parents "rich" by any stretch. Secure, yes, maybe even "well off" - but certainly not "rich" to the degree that we're discussing here. To a single person working in New York with a salary of $750k, establishing residency in Jackson Hole, Wyoming would save them $50k / year in state income taxes alone.
