According to Abreu, if Empower is facilitating as many as one million rides per month in New York City, the unpaid congestion fees could amount to tens of millions of dollars annually that would otherwise help fund the region's transit system. He has asked the MTA to determine how many Empower trips entered the congestion pricing zone without paying the required toll, calculate any missing revenue and pursue repayment if appropriate. The company says it has repeatedly offered to work with city officials to facilitate payment of any applicable taxes or congestion charges but claims those proposals were rejected. The controversy adds to Empower's broader legal challenges in New York. The city has already filed suit, alleging the company is effectively operating as an unlicensed rideshare service while avoiding the regulatory requirements and costs imposed on its competitors.
