You need to fill the form UT-11 at DMV office or a DMV Call Center.
And what should I do if I live outside of New York and I am also exempt from the vehicle use tax in my county?
In that case, the form you must fill out is the UT-11C.
I am going to register my vehicle and I don't know if I have to pay a vehicle use tax or where to pay. Can you help me?
