Democratic darling Alexandria Ocasio-Cortez still hasn’t paid a six-year-old tax bill left over from a failed business venture.

Weeks after The Post alerted the freshman Congresswoman’s office to the outstanding tax lien from 2012, she still hasn’t paid it, state records show.

Brook Avenue Press, a company set up in the Bronx to publish books about city children, owes $1,877.56 in unpaid corporate taxes.

The state slapped the company with a warrant on July 6, 2017, two months after Ocasio-Cortez announced her candidacy to run against Democratic incumbent Joe Crowley for the district that encompasses parts of Queens and The Bronx.

Public records show the state dissolved the company in October 2016, which can happen when a business fails to pay corporate taxes or file a return.

A spokesman for Ocasio-Cortez, who has called for sweeping tax hikes on the rich, told The Post two weeks ago that the taxes would be paid right away.

But on Thursday, her aide Corbin Trent said that the Congresswoman’s lawyers were looking into the matter.

“I’m her congressional staffer, not her personal accountant,” he said.
