If you have purchased a Washington state-titled vehicle or received one as a gift, you are required to transfer the title within 15 days. After 15 days, a monetary penalty will be assessed. You need to take the following documents to your local license agency: the current title with the signatures of the previous owners releasing interest; a bill of sale stating the full purchase price or statement of a gift signed by the previous owner, and a completed odometer disclosure statement if the vehicle is less than 10 years old. If this is a gift, you will also need to provide proof of sales tax paid by the previous owner.
The cost to transfer a title is $42 plus 9.0% use tax, if applicable. Use tax is not charged on gift transactions if the sale / use tax has already been paid by the donor.
