Still, Democrats are jazzed over the chance to restore a tax break that they say was included in the 2017 law by Republicans to hurt taxpayers in Democratic-leaning districts, including middle-income earners in areas where housing is expensive and taxes are high. Liberals see the cap as part of a broader strategy by conservatives to undermine support for progressive agendas.

“With Democrats in complete control of the federal government, and New York’s senior senator in charge of the Senate agenda, our chances for giving tax relief to middle class New Jerseyans have never been better,” Representative Bill Pascrell said in a statement. “I’m already working with my colleagues in the delegation who are chomping at the bit to restore the SALT deductions Republicans stole from our neighbors in their 2017 tax scam.”

Representative Tom Suozzi, a New York Democrat, is among the legislators leading the charge to repeal the cap. He said he wants it repealed in its entirety.

“The SALT deduction is based upon basic fairness,” Suozzi said. “You shouldn’t be taxed on taxes you have already paid.”

“The second part of the fairness issue is that state and local governments have been operating under this paradigm for a hundred years,” he added.

Shepherding the vote through the House and Senate will require the slim Democratic majorities in both chambers to stay united on what is likely to be a complex and sweeping economic policy bill.

The SALT repeal would likely be bundled with dozens of other tax and spending provisions in what’s known as a budget reconciliation bill, a fast-tracked process to pass legislation with a simple Senate majority -- rather than the normal 60-vote threshold.

That way, the chamber’s 50 Democrats, combined with a tie-breaking vote from soon-to-be Vice President Kamala Harris, could pass the legislation without needing any Republicans to sign on.

Democrats have a long trail of defeats trying to get rid of the SALT cap. New York Governor Andrew Cuomo went to court to invalidate the law. Governors of Democratic-led states, including Cuomo, then tried to use the judicial system to throw out regulations regarding the cap. So far, both efforts have failed.
