ALBANY — Gov. Andrew Cuomo has been begging rich people to return to New York City from their second-home retreats so they can pay taxes to help offset the state’s growing coronavirus-related revenue shortfall.
“I literally talk to people all day long who are now in their Hamptons house who also lived here, or in their Hudson Valley house, or in their Connecticut weekend house, and I say, ‘You got to come back! We’ll go to dinner! I’ll buy you a drink! Come over, I’ll cook!’” the Democratic governor said Monday.
“They’re not coming back right now. And you know what else they’re thinking? ‘If I stay there, I’ll pay a lower income tax,’ because they don’t pay the New York City surcharge,” he added, noting the wealthiest 1 percent of the Empire State’s population picks up roughly 50 percent of the state’s tax burden.
