START-UP NY: MCTMT exemption for employers

The metropolitan commuter transportation mobility tax (MCTMT) exemption eliminates the MCTMT on the payroll expense attributable to an approved business location within the MCTD* for 40 consecutive calendar quarters. The exemption begins with the calendar quarter during which the business locates in the tax-free NY area.

How to compute your MCTMT

Step 1     Calculate your total payroll expense for employees within the MCTD. 

  • Include all employees within the MCTD, including those inside and outside the tax-free NY area. 
  • Use this amount to determine the rate at which your tax is calculated (.11%, .23% or .34%; see Employers: MCTMT).

Step 2     Then subtract from the total payroll expense the amount of payroll expense from the tax-free NY area within the MCTD.

Step 3     Multiply the amount in Step 2 by the rate determined in Step 1.

Example: Taxpayer A has payroll expense of $500,000 in the MCTD of which $300,000 is payroll expense attributable to a tax-free NY area within the MCTD. Since the payroll expense is over the threshold of $437,500 the applicable rate is .34%. Taxpayer A's MCTMT is $680 ($200,000 x .34%).
