Is a bill of sale required to sell a car in Oklahoma?
Oklahoma does not legally require a separate bill of sale for standard private-party vehicle transfers when a properly assigned and notarized title is provided. However, purchase price documentation is required — this can be the price recorded on the title, a bill of sale, or a completed Declaration of Vehicle Purchase Price (Form 722-1). Starting July 1, 2025, all Oklahoma titles are issued electronically, and for vehicles with electronic titles, the seller must use Form 718 (Bill of Sale of an Electronic Title), which is required and must be notarized.
Does an Oklahoma title need to be notarized?
Yes. Oklahoma requires the seller's signature on the title assignment to be notarized for all standard transfers. This applies to both paper and electronic titles. For paper titles, the seller signs the assignment on the back of the title in front of a notary. For electronic titles (all new titles issued after July 1, 2025), the Electronic Title Bill of Sale (Form 718) must be notarized. Oklahoma caps notary fees at $5 per act. A bill of sale used only to establish the purchase price — not to convey ownership — does not need to be notarized.
What taxes and fees does the buyer owe?
Oklahoma charges a 3.25% excise tax on the purchase price, provided the price is within 20% of the vehicle's average retail value. If the stated price falls outside that range, the tag agency will establish a taxable value within the acceptable range. In addition, a 1.25% sales tax applies to all vehicle transfers with a sale date on or after July 1, 2017. The combined effective rate is 4.5% — one of the lower rates in the country. The buyer has 30 days to complete the title transfer; after 30 days, a penalty of $1 per day is assessed for each day the transfer is late.
Transfers between qualifying family members — spouse, parent (including step-parents), and children (including step-children) — are exempt from excise tax. Siblings and other relatives do not qualify.
What should the seller do after the sale?
The seller may optionally file a Notice of Transfer of Ownership (Form 773) with Service Oklahoma for a $17 filing fee. This is not legally required but protects the seller from future liability. The seller must remove their license plates — Oklahoma plates belong to the seller and can be transferred to another vehicle or returned to the tag agency. The seller should keep a copy of the notarized title or Electronic Title Bill of Sale for their records.
What if the vehicle has multiple owners?
If the vehicle is titled to more than one person, all owners on the title must sign the bill of sale. Use the "Add a co-seller" option on the form to add the second seller's name and address. Both sellers' names and signature lines will appear on the document. For electronic signing, each co-owner can sign on the same device in sequence, or the document can be passed from one device to another via QR code or shared link. Both buyers can likewise be named on the bill of sale using the "Add a co-buyer" option.
Governing law
Oklahoma vehicle transfers and their supporting records are governed by the Oklahoma Statutes. The provisions below set the framework for private-party sales and title transfer.
Vehicle title transfers in Oklahoma are governed by Oklahoma Statutes Title 47, particularly 47 O.S. §1107 (sale or transfer of ownership). The 3.25% excise tax and 1.25% sales tax are administered by Service Oklahoma through licensed tag agents. Starting July 1, 2025, all titles are issued electronically; private sellers use the Electronic Title Bill of Sale (Form 718) for electronic title transfers. Federal odometer disclosure requirements are established by 49 U.S.C. Chapter 327 and 49 CFR Part 580.
