Did you aready send any documents to DMV?
Yes, I sent two documents but It seems that either, those were wrong documents, or I missed some documents when I sent them.
Ok, no problem. I'll tell you what documents you need to send; if you already sent one of the documents on the list, simply send the ones you didn't send. DMV save all of that, so when you submit the ones you missed DMV will start your process.1)  A completed Application for Duplicate Title PDF  MV-902s2) Proof of Identity: this can be a photocopy of your NY State driver license, driver permit, or non-driver ID. You can see the Title PDF ID-82 for more acceptable proofs. 3 A personal check or money order for $20, paytable to Commissioner of Motor Vehicles
Now, about County use tax chart, I have one, but unable to understand it. Can you clarify it to me, please?
The chart shows you a list of counties: find the one you are living in and see the amount of the use tax.You also have one chart for the registration fee depending on how much your vehicle weights.
I have some questions regarding those taxes, with whom should I talk?
You can ask the city or county where you reside. They will help you.
Ok, because it seems that I am exempt from the vehicle use tax in my county.
