Kill this tax bill

Thursday, the U.S. House will vote on a bill that threatens to rip billions of dollars from New York taxpayers and further skew an economy that’s already obscenely tilted toward the wealthiest Americans. What the Republicans call “tax reform” is actually a massive scam — one all New York Republicans must vote against.

Alas, only Pete King, Dan Donovan, Lee Zeldin, John Faso and Elise Stefanik are avowed “no” votes.

Conversely, Chris Collins, Tom Reed, John Katko and Claudia Tenney have opted to betray the best interests of their state.

What the hell could they be thinking? The bill is a daylight mugging of New York and other deepblue states. Its near-total elimination of the state and local tax deduction will wallop Empire State taxpayers alone to the tune of $12 billion annually.

And the Great Blue State Robbery is only one fetid piece of a bill that’s rotten in dozens of ways.

By ending the estate tax, cutting the rate on pass-through income, eliminating the Alternative Minimum Tax and cutting the top income-tax rate, it lavishes benefits on the wealthiest Americans while delivering paltry benefits or tax hikes to middle- and working-class families — which conveniently expire within five to ten years.

Over a decade, the overall effect of the cuts will add at least a $1.5 trillion to already-ballooning deficits and trigger steep automatic cuts to Medicare and other vital programs.

As of this week, Senate Republicans further poisoned the well by tossing in repeal of the Affordable Care Act’s individual mandate into their version of the tax package. That sneak attack would leave 13 million more Americans uninsured within a decade.

If there’s any silver lining in this godforsaken process, it’s that Republicans are testing even their own members’ sanity.

Wisconsin’s Ron Johnson became the first declared vote against the current Senate bill. He says it’s too generous to corporations and insults the legislative process.

In that regard, he sounds like King, who told The News Wednesday, “We may be setting tax policy for the next 30 years. And now, the Senate wants to throw in health policy with tax policy? How can they do that without any hearings or outside experts?”

How indeed?
