Please see the following link to view and download or print the Massachusetts Income Tax Vouchers for Individuals as well as the instructions (and address for mailing) for them:http://www.mass.gov/dor/docs/dor/forms/inctax16/f1-nrpy/pv.pdf 

If you need to mail your payment with your Massachusetts Resident Income Tax return, make your check or money order payable to the Commonwealth of Massachusetts and write your Social Security number on the front of your check or money order in the lower left corner. Complete and remove Form PV, Mass- achusetts Income Tax Payment Voucher, attached to the back of the envelope included in this book- let. Enclose the check and Form PV (the one listed in the link above) with your return. Form PV must be included with your check to ensure proper crediting of your account.
