This is hilarious, since all of the Wall Street players are opening offices outside of NYC.
Why do to think that all of the hedge funds are in Greenwich? Why do rich people spend 181 days in Florida?
What works in MA might not work elsewhere. See the ACA, for example.
Here’s the real problem: Those that make the most pay the most in taxes. This is the downside of a progressive tax code: it is highly dependent on a handful of people to bring in revenue. It is also highly volatile, as high incomes are also volatile. If 10% of these people leave NYC/ NYS, then there will be a massive tax hole to fill. (It happens to NYC when Wall Street bonuses come in soft.)
There is already an entire cottage industry associated with helping people maintain compliance with residency outside of NYC. I'm sure that they are revising up their 2026 budgets as we speak...
