Are there sales taxes both on vehicle purchase and on vehicle registration with the DMV?
The DMV does not collect sales tax when you apply for a vehicle registration if NY State sales tax was paid to a NY State dealer and will, for that reason, not issue a sales tax receipt.
What will I need to do when I register my vehicle in New York at a DMV office as far as sales taxes?
When you register your vehicle you must either pay the sales tax, prove that the sales tax was paid, or prove that your vehicle registration is exempt from sales tax.
