Cuomo said, though, that thanks to the curbing of the SALT deduction, the proposal would dramatically boost the overall amount of money that New Yorkers pay on their federal taxes.

He noted that New York already sends $48 billion more to Washington annually than it gets in federal benefits -- a situation that would get worse under the GOP tax plan.

"You're going to pay for a corporate tax break on the backs of New Yorkers?" he asked.

Schumer said the compromise that Republican House leaders agreed to in the bill – continuing to let homeowners deduct most of their property taxes while ending the deduction for state and local income taxes – still does grievous harm to the state. That's because the compromise eliminates 71 percent of the benefits of the SALT deduction.

"It's as if they are saying: 'Now we'll only chop off three or four of your fingers. Aren't we doing you a big favor?' " Schumer said.

Cuomo and Schumer restated their case in support of the SALT deduction as the Government Finance Officers Association released a report that offered new details on how many taxpayers use that tax break.
