If the value of the car, when you gift it, is more than $16,000, you have to file a federal gift tax return, Form 709. You will not have to pay any gift tax unless the total of all gifts you have made in your lifetime is more than $12 million, but you have to file the return.
If the value of the car is $16,000 or less there is no tax, and you do not have to do anything.
