I don't have an opinion one way or the other on this, but I do remember it happened at least once before:
"Three-time gubernatorial candidate and billionaire B. Thomas Golisano is changing his home address to Florida to escape New York income taxes he says cost him nearly $14,000 a day."
That's from 2008 and I don't think he lived in the city, so maybe not exactly a perfect example but all he had to do was "change his home address"?
When you're a billionaire, sure. Like the IRS is going to call you on it.
Also, he's claiming he owed ~$5 million a year in taxes. Which is a lot, but he spent $93 million to run for governor, and basically flushed all that money down the loo. He apparently has spent hundreds of millions on various charitable projects. So clearly, the taxes are not really burdensome. He just doesn't think he should have to pay them.
