The MTA plans ramp up Manhattan’s congestion pricing tolls to $15 in 2031 — a sharp increase from the $9 charge Gov. Kathy Hochul announced last week, according to documents published by the transit agency.

The documents show the price of the base toll for passenger vehicles will grow to $12 in 2028. Hochul’s office last week acknowledged the prices would eventually increase — but did not specify an exact timeline.

“The governor has been very clear that she does not want it raised for at least three years, and then we will file, the MTA will file, what possible phase-in would look like up to $15,” director of New York state operations Kathryn Garcia said at a new conference last week unveiling the new plan.

The MTA cleared up what that phase-in would look like on Friday by publishing a resolution slated to be approved by the agency’s board on Monday. The agreement allows the agency to officially sign off on the Jan. 5 launch of the $9 base toll — as well as the plan for the price increases down the road.

The board documents state the price increases are necessary so the tolls can fund $15 billion worth of MTA repairs and upgrades, which is required by state law.

The relaunch of congestion pricing came more than five months after Hochul abruptly put the tolling program on pause. The MTA previously planned to move forward with a $15 toll price for congestion pricing on June 30, but the governor pumped the brakes weeks ahead of the launch, saying the fee was too high for drivers at the time.

Hochul was quick to move on a new plan to revamp congestion pricing in the days following the presidential election, where Republicans won control of the White House and both chambers of Congress. President-elect Donald Trump vowed to kill the Manhattan tolls earlier this year — and the MTA’s planned start date for the charges is scheduled just 15 days before his inauguration.

Danny Pearlstein, spokesperson for the transit advocacy group Riders Alliance, said many drivers would be upset by any congestion pricing toll — no matter the price.

“Even a 50-cent toll would’ve sent some people through the roof, so there’s no getting around that,” Pearlstein. “But this is absolutely compromised from what came before and it’s significantly different for the MTA. The money will definitely roll in slower, the nudge to drivers to get off the road, to cancel or combine their trips, is definitely a lighter touch.”
