New York is appealing the decision that tossed a lawsuit challenging the federal government’s $10,000 cap on state and local tax deductions.

The suit was filed with New York, Connecticut, Maryland and New Jersey. The appeal was filed with the federal U.S. Court of Appeals for the Second Circuit.

“The Trump administration’s SALT policy is retribution politics – plain and simple,” Gov. Andrew Cuomo said in a statement.

“New York is already the nation’s leader in sending more tax dollars to Washington than we get back every year, and we will not allow this administration to pick the pockets of hard-working New Yorkers to fund tax cuts for corporations and send even more money to red states. We will continue to fight this unconstitutional assault until it is repealed once and for all.”

The 2017 tax law capped state and local deductions, a move that affected high tax states like New York.

“This cap has already put a heavy burden on the hard-working, middle-class families of New York, and, in the years ahead, it is expected to cost New York’s taxpayers over $100 billion, which is why we will fight this senseless and unconstitutional law,” said Attorney General Letitia James. “New York will not be bullied into paying more in taxes or changing its vital public investments because of Congress and the president’s partisan choices.”
