I have a number of retired wealthy friends and some of them have moved to take advantage of lower taxes - these are folks with a least two homes. A couple of them moved to Texas, and numerous of them have moved to Florida. Mind you, most still have a home in NYC, but for tax purposes they are domiciled elsewhere. NYC is pretty strict about chasing down locational arbitragers, so I see my friends playing all kinds of games - like paying for everything in cash whenever they are in the city, or routing expenses through an LLC (or other trust or c-corp) established solely for this purpose. I would be playing some of these games except I need to retain my NYC residency status in order to get the homeowner capital gains exemption when we sell our place. Once that's done, I'm outta here, at least for residency purposes.
