UTICA, N.Y. -- Some upstate lawmakers are saying the numbers don't add up with the GOP's proposed tax cut.

Congressional candidate Anthony Brindisi and Oneida County Executive Anthony Picente said it eliminated a key tax deduction for residents.

They focused on the state and local tax deduction known as SALT. It could be eliminated if the Republican plan passes in Washington.

A Government Finance Officers Association study says many homeowners could end up paying more because of it in New York. Their review looked at how it would impact homeowners in districts of Representatives Claudia Tenney, John Katko, John Faso and Elise Stefanik.

In Tenney's 22nd District, the study claims 60 percent of single filers would have an average increase of $469. Nine percent of married couples filing jointly would see an average of a $463 increase. Other districts could see higher increases.

Brindisi is calling for local representatives to act.

"What I would recommend is that our House delegation do not vote for this bill, go back to their leadership and say, 'We want to see a tax cut that actually benefits middle class New Yorkers, not something that's going to raise our taxes here,' " said Brindisi.

Tenney is Brindisi's opponent next fall. A spokesperson for her said she is also working to protect the state and local tax deduction.
