What is MCTMT?

The Metropolitan Commuter Transportation Mobility Tax (MCTMT) is a New York state specific tax that is collected by the New York State Tax Department for the Metropolitan Transportation Authority. This tax is charged to certain employers and self-employed individual engaging in business within the metropolitan commuter transportation district (MCTD).

The MCTD is made up of 12 counties that benefits from the MTA’s services. The specific counties that are part of the MCTD are: New York (Manhattan), Bronx, Kings (Brooklyn), Queens, Richmond (Staten Island), Rockland, Nassau, Suffolk, Orange, Putnam, Dutchess, and Westchester. If you're headquartered in any of these counties or have employees who work out of an office there, you might be subject to MCTMT.

When does the tax apply?

Companies are required to pay MCTMT if the sum of their payroll expense for all employees in the MCTD exceeds $312,500 for that calendar quarter. If you’ve paid more than $312,500 in salary expenses in one quarter to employees based in these 12 NY counties, then you will be subject to MCTMT.

This tax is calculated quarterly. This means that an employer whose payroll expense for a quarter does not exceed $312,500 is not subject to the MCTMT for that quarter, even if the employer’s payroll expense may have been more than $312,500 in a previous quarter.

The MCTMT rate is directly dependent on the payroll expense. This is how it breaks down as of April 1, 2012:

Payroll Expense


Over $312,500 but not over $375,000

.11% (.0011)

Over $375,000 but not over $437,500

.23% (.0023)

Over $437,500

.34% (.0034) 


MCTMT is due on the last day of the following month after the calendar quarter ends. Below are the quarter break downs

If you are not subject to the MCTMT for a quarter ,you are not required to file a quarterly MCTMT return for that quarter. However, if you become subject to the MCTMT in a subsequent quarter, you must file a quarterly return and pay the tax due.
