Free Washington Vehicle Bill of Sale
Washington vehicle sales hinge on three deadlines that protect the seller more than anywhere else in the country. First, Form TD-420-065 (the state-published bill of sale) documents the price for use-tax purposes — and with combined rates that top 10.5% in the Seattle area plus a statewide 0.5% motor vehicle sales/use tax, the tax math matters. Second, the buyer has just 15 days to title-transfer through WA DOL using Form TD-420-001 — miss it and penalties climb $2/day to $125. Third, and most critical, the seller has 5 business days to file a Vehicle Report of Sale online at dol.wa.gov — file it and any tickets, tolls, or parking citations after that date go to the buyer, not you. Skip this step and you stay liable. Use tax is figured on the higher of the price or fair market value under DOL's valuation rules, so write the real price.

Washington Vehicle Bill of Sale — What You Need to Know
Sales Tax Details
Washington charges 6.5% state sales/use tax PLUS local rates — combined rates run from under 8% to over 10.5% depending on county and city (Seattle is 10.55%). On top of that, every vehicle purchase in the state pays an additional 0.5% motor vehicle sales/use tax (raised from 0.3% on January 1, 2026). Use tax is calculated on purchase price OR fair market value, whichever is higher, under DOL's valuation rules.
Exemption: Gifts and family transfers: confirm with WA DOL whether the transfer is exempt from use tax and what documentation it needs before assuming no tax is due.
Inspection Requirements
Washington has NO state safety inspection requirement, and statewide emissions testing was discontinued in January 2020 (previously required in Clark, King, Pierce, Snohomish, and Spokane counties). A Washington State Patrol inspection is required only in special cases — rebuilt vehicles, homemade vehicles and trailers, vehicles reported stolen, or vehicles without a proper VIN — and the licensing agent tells you if you need one.
Registration
Registration for this vehicle type is handled by Washington Department of Licensing (DOL) — vehicle licensing offices and subagents statewide — not the same agency that handles cars in Washington. Plan for separate filings.
Washington Vehicle Sale — Step-by-Step Checklist
- Complete Form TD-420-065 (Vehicle/Vessel Bill of Sale) with full names, addresses, VIN, year/make/model, price, and date — both parties sign.
- Seller signs off the Washington Certificate of Title (back) and completes the federal odometer disclosure for vehicles of model year 2011 or newer.
- CRITICAL: Seller files a Vehicle Report of Sale online at dol.wa.gov within 5 business days — this is the single most important seller-protection step in WA.
- Buyer applies for title transfer at any DOL office or vehicle licensing subagent within 15 days using Form TD-420-001 to avoid escalating penalties.
- Buyer pays 6.5% state sales/use tax plus local rate (check DOR's rate lookup for the buyer's address) calculated on the higher of purchase price or fair market value.
- All Washington buyers also pay the statewide 0.5% motor vehicle sales/use tax at title transfer (it was 0.3% through 2025).
- For a gift or family transfer, confirm with WA DOL how to report it and what documentation it needs before assuming no use tax is due.
- Seller removes license plates — Washington plates stay with the seller, not the vehicle.
Common Pitfalls
- Skipping the 5-day Report of Sale filing — this is the single biggest WA mistake. Without it, the seller stays on the hook for the buyer's parking tickets, toll violations (Good To Go!), red-light camera tickets, and even abandoned-vehicle fees indefinitely.
- Underreporting the sale price on TD-420-065 to dodge use tax — misreporting the price is tax fraud, and DOL's valuation rules can base the tax on fair market value anyway.
- Missing the 15-day title transfer deadline — penalties start at $50 and escalate $2/day up to $125, on top of the already-due sales tax and license fees.
- Forgetting the statewide 0.5% motor vehicle sales/use tax — every vehicle buyer pays it on top of the regular sales/use tax.
- Leaving plates on the vehicle — WA plates belong to the seller and must be removed before delivery; buyers must obtain new plates at title transfer.
- Claiming a family gift without the documentation WA DOL asks for — confirm the paperwork before the title visit.
Pro Tip
The Washington playbook: complete TD-420-065, file the Report of Sale within 5 business days (this is the seller-protection step nobody in other states has), buyer titles within 15 days using TD-420-001, and budget for state plus local sales/use tax plus the statewide 0.5% motor vehicle tax.
