“However, New York also has a provision called tax-benefit recapture, which essentially turns its progressive tax into a flat tax for high earners, says Eric Bronnenkant, head of tax at Betterment and a certified public accountant.”

If you are at all at risk of earning $25 million in a given year, throw a few bucks at a tax advisor to ensure you avoid this pitfall.

Everyone else, carry on. Nothing to see here.

I see you made it to the fourth bullet point in the first paragraph of one of the two links.

It actually matters - or can matter, anyway - if you have any event pushing your income above $1M (if filing single) because of the change in deduction treatments.

The actual effect of recapture schemes is to increase marginal tax rates on mid-high incomes while leaving the highest brackets mostly untouched, and then lie about it.

Are you saying New York has an income tax that does not feature marginal tax rates?

Yes, I am saying that.
