In a last-ditch effort to save the state’s soon-to-expire “millionaires’ tax,” Assembly Speaker Sheldon Silver floated plans yesterday to alter it to hit only New Yorkers who actually make more than $1 million annually.

The powerful Assembly speaker told the upstate news network YNN that he will unveil a budget resolution to raise the threshold for the tax to kick in from the current $200,000 a year for individual taxpayers.

“We may adjust that to conform to the sound bite, all the way to a million,” said Silver (D-Manhattan). “We’ll get the revenue that that brings, but not significantly less, I might tell you.”

An extension of the tax faces stiff opposition from Gov. Cuomo and Senate Majority Leader Dean Skelos (R-LI), and Silver admitted in an interview with The Post last week that it had little chance of passage.
