County executives from both parties stood together in Albany on Thursday to criticize the Republican plan in Washington to overhaul taxes, saying the push to end deductions of state and local taxes will take a hit on their budgets -- a development that could lead to less tax revenue and potential cuts in spending.

"The impact will be felt pretty immediately as people do adjust their withholdings and paychecks will limit certain spending and perhaps put some money away and not in the marketplace," said Dutchess County Executive Marc Molinaro. "I think we will see sales tax receipts not grow as we hoped. That's a concern."

County budgets are usually in place by the end of the calendar year. But county executives say that impact of ending deductions for state and local taxes and capping property tax deductions at $10,000 could have reverberations within the next 12 months, forcing some people to leave the state.

"That will have an ultimate impact because it will be a trickle-down effect, if you will, in the negative," said Molinaro, a Republican.

The county executives of Albany, Dutchess and Suffolk counties say they've already finalized their 2018 budgets without considering the impact of ending the deductions, known as SALT. 

"It was almost inconceivable that it could happen," said Suffolk County Executive Steve Bellone, "and yet we're now at a point that there's a likelihood it could actually happen."

Albany County Executive Dan McCoy says county governments in New York could be squeezed by both the federal tax measure and the state budget troubles expected in 2018.

"It's not going to change because it's only going to get worse," McCoy said. "And I want to tell people that you better brace yourself, because what's going on on the state side and the federal side, it's going to affect our counties."

Potential gubernatorial candidate Molinaro says both the federal and state government have a role to play. 

"It's making sure SALT is maintained and a commitment at the state level to try to draw down property taxes," he said.

Both the House and Senate versions of the tax bill would end the SALT deductions.
