How to Sell a Car Privately in Washington (2026 Guide)
Quick Answer
To sell a car privately in Washington you need: a signed title, a completed bill of sale (VIN, sale price, odometer, date, both signatures), and photo ID. The buyer has 15 days to transfer the title at the Washington DOL and pay the $12 transfer fee plus pass an emissions test.
Washington-Specific Note
Washington title and registration is handled by the Department of Licensing (DOL), not a standard DMV. Washington has some of the highest combined local sales tax rates in the country for vehicle purchases. Electric vehicles also pay an annual Electric Vehicle fee.
Step-by-Step: How to Sell a Car Privately in Washington
Follow these 7 steps in order. Do not skip step 6 — a missing or incorrect bill of sale is the #1 reason title transfers are rejected by the Washington DOL.
- 1Price your vehicle using Kelley Blue Book (kbb.com) and Edmunds (edmunds.com) to establish fair market value. Cross-reference at least two sources. Set your asking price 5–10% above your walk-away number to leave negotiating room.
- 2Gather your documents before advertising: the clear title (no open liens), valid government-issued photo ID, maintenance records, and any warranty paperwork. If there is an open lien, contact your lender to arrange a payoff and lien release before listing.
- 3Run a VIN history report and share it with prospective buyers. Reports from Carfax or AutoCheck cost around $40 and show accident history, odometer records, and title status. Serious buyers expect this — having it ready prevents the "I need to check the VIN" negotiating tactic.
- 4Photograph and list the vehicle with full details: mileage, options, maintenance history, and known condition. State "as-is, private sale" clearly in the listing. Use at least 10 photos taken in daylight from multiple angles.
- 5Screen buyers: allow test drives only after requesting a valid license. Meet in a public location (a bank parking lot is ideal — you can accept a cashier's check on the spot). Never allow an unsupervised test drive.
- 6Complete a Washington bill of sale at the time of the sale. Both buyer and seller must sign. The document must include the VIN, sale price, odometer reading, sale date, and full names and addresses of both parties.
- 7Sign over the title to the buyer. The seller signs the assignment section on the back of the title. Double-check every field — an incorrect title is rejected by the Washington DOL. The buyer has 15 days to complete the title transfer.
Required Paperwork for a Washington Private Car Sale
Signed vehicle title
The seller signs the back of the Washington title in the assignment section. Fill in the buyer's full legal name, sale price, and date. Do not leave any field blank.
Bill of sale
Must include: buyer and seller full names and addresses, VIN (17 characters), year, make, model, odometer reading in miles, sale price (written and numeric), sale date, and both parties' signatures.
Odometer disclosure
Required by federal law (Truth in Mileage Act) for vehicles under 10 model years old. Washington also requires odometer disclosure under state law. Record the exact odometer reading at the time of sale.
Government-issued photo ID
Both parties should bring a valid driver's license or state-issued ID. This confirms identity and reduces fraud risk. Make a photocopy for your records.
Emissions / smog certificate
Vehicle Emission Testing is required in parts of King, Pierce, Snohomish, Clark, and Spokane counties. Check the DOL website at dol.wa.gov to confirm whether your vehicle's county requires testing.
Washington DMV Information and Fees
Protect Yourself After the Sale
Signing over the title and handing over the keys does not automatically end your liability in Washington. If the buyer is involved in an accident, receives a traffic citation, or accumulates unpaid tolls before transferring the title, you may receive notices — or worse, have your license suspended.
Notify the Washington DOL of the sale by completing the back of the title. Remove your plates — Washington plates transfer with the owner to the next vehicle. File a report of sale at dol.wa.gov.
3 Common Mistakes When Selling a Car in Washington
Not completing a Washington State Bill of Sale — while not legally required, the DOL strongly recommends a signed bill of sale to prove the sale price for accurate use tax calculation.
Forgetting emissions testing — Washington requires testing in parts of King, Pierce, Snohomish, Clark, and Spokane counties. Vehicles in these counties must pass emissions before re-registration.
Not canceling your title within 15 days — Washington requires the buyer to transfer the title within 15 days of the sale. Sellers should follow up to confirm the transfer was completed.
Frequently Asked Questions
What paperwork do I need to sell a car privately in Washington?▾
To sell a car privately in Washington, you need: (1) the vehicle title signed and dated by the seller; (2) a completed bill of sale with VIN, sale price, odometer reading, sale date, and both parties' signatures; (3) valid government-issued photo ID; and (4) an odometer disclosure statement for vehicles under 10 model years old. A VIN history report, while not required, is strongly recommended to reassure buyers and justify your asking price.
How long does the buyer have to transfer the title in Washington?▾
In Washington, the buyer has 15 days from the date of sale to transfer the title at the Washington DOL. Missing this deadline results in late fees. Sellers should file a notice of sale with the Washington DOL promptly after the sale to avoid liability for post-sale incidents.
Does Washington require a notary for a private car sale?▾
No — Washington does not require notarization for a standard private car sale. Both parties simply need to sign the bill of sale and the seller signs the back of the title. Voluntary notarization is always an option for extra legal protection, particularly for high-value vehicles.
How much is the title transfer fee in Washington?▾
The title transfer fee in Washington is $12. This fee is paid by the buyer at the Washington DOL at the time of registration. In addition to the title fee, the buyer pays Washington charges 6.5% state sales tax plus local taxes (up to ~10.4% in Seattle). Use tax is due when the buyer registers the vehicle. The DOL uses the stated purchase price for tax calculation. Registration fees are also due at that time.
Can I sell a car without a title in Washington?▾
Selling a vehicle without a clear title in Washington is strongly discouraged and may be illegal. If you have lost the title, apply for a duplicate title at the Washington DOL before listing the vehicle. If you have an outstanding loan, contact your lender to arrange a payoff and lien release. Buyers who purchase a vehicle without a proper title will have serious difficulty registering it.
