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 sales-tax purposes — and with combined rates of 7%–10.4% plus a 0.3% Sound Transit MVET in the Seattle/Tacoma metro, 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. Washington has no state income tax, so DOL aggressively audits low-priced bills of sale against NADA values to protect sales/use tax revenue.

Washington Vehicle Bill of Sale — What You Need to Know
Sales Tax Details
Washington charges 6.5% state sales/use tax PLUS local rates of 0.5%–3.9% — effective combined rates run 7.0%–10.4% depending on county and city (King County/Seattle is at the high end at 10.25%–10.4%). On top of that, vehicles in the Sound Transit district (Seattle/Tacoma metro) pay an additional 0.3% Motor Vehicle Excise Tax (MVET) for regional transit. Use tax is calculated on purchase price OR fair market value, whichever is higher — DOL uses NADA/Kelley values to challenge suspiciously low bills of sale.
Exemption: Family transfers between spouse, parent, child, sibling, grandparent, or grandchild are exempt from sales/use tax with a signed affidavit (Form TD-420-038). Gifts (zero consideration) are also exempt. Inheritance, divorce decree, and trust transfers exempt with documentation.
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). VIN inspection is required only for out-of-state vehicles, rebuilt titles, and homemade trailers — performed at WSP inspection stations or licensed inspectors.
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 under 20 model years old.
- 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 (7%–10.4% total depending on city/county) calculated on the higher of purchase price or NADA fair market value.
- Sound Transit district buyers (Seattle/Tacoma metro) pay an additional 0.3% MVET for regional transit at title transfer.
- For family transfers (spouse, parent, child, sibling, grandparent, grandchild), file Form TD-420-038 affidavit to claim sales-tax exemption.
- 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 sales tax — WA DOL cross-checks against NADA Clean Retail values and assesses use tax on the higher figure, plus penalties. With no state income tax, sales/use tax enforcement is aggressive.
- 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 0.3% Sound Transit MVET in King, Pierce, and Snohomish counties — buyers in Seattle/Tacoma metro pay this on top of regular sales tax, often surprising people moving from outside the district.
- 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.
- Family transfer exemption without the affidavit — verbal claims of "it's a gift to my brother" don't fly. Form TD-420-038 must be filed at title transfer or full sales tax applies.
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 7%–10.4% for sales/use tax plus 0.3% MVET in the Seattle/Tacoma metro.
