As New York State and City extend high-income surcharges and debate still-higher corporate rates, any new levy or extension that reaches back to tax income earned before a company relocates to Florida or Texas effectively functions as a retroactive exit penalty—one that punishes firms for succeeding in New York under yesterday’s rules.
