Free Oregon Used Car Bill of Sale
A used-car sale in Oregon is about as buyer-friendly as it gets in America: no state sales tax, no use tax on private sales, no smog check outside the Portland and Medford metros, and a clear DMV form (735-501) that the state itself publishes. Compare that to neighboring Washington (6.5% sales tax + 0.3% MVET) or California (7.25% base + local), and you understand why Oregon plates show up at out-of-state used-car lots. The catch — there is always one — is the seller's 10-business-day Notice of Sale window. Miss it, and the buyer's sins become yours until the title actually transfers.

Oregon Used Car Bill of Sale — What You Need to Know
Sales Tax Details
Used cars sold privately in Oregon carry ZERO sales tax. Oregon is one of just five no-sales-tax states, and there is no use tax loophole that catches private buyers. The 0.5% Vehicle Privilege Tax is dealer-only on NEW cars — it never touches a private used-car deal.
Exemption: Private-party used vehicle sales are tax-free by default — Oregon has no state sales tax to exempt from.
Inspection Requirements
No statewide safety inspection. DEQ emissions testing is mandatory only in the Portland metro (Multnomah, Washington, Clackamas) and Medford metro (Jackson County). Vehicles 1975 and older are exempt; new vehicles get a grace period.
Registration
Registration for this vehicle type is handled by Oregon DMV — not the same agency that handles cars in Oregon. Plan for separate filings.
Oregon Used Car Sale — Step-by-Step Checklist
- Both parties complete Form 735-501 with VIN, odometer reading, year/make/model, sale price, and date
- Seller signs the title over and fills in the odometer disclosure on the reverse
- Disclose any brand titles (salvage, reconstructed, flood, lemon-law) on the bill of sale
- Seller files the free Notice of Sale online within 10 business days
- Buyer applies for title transfer within 30 days using Form 735-226
- Buyer schedules DEQ emissions if garaged in Portland or Medford metro
- Buyer pays $101 title fee plus registration (county-dependent)
- Keep signed copies of bill of sale and title for at least 3 years
Common Pitfalls
- Hiding a salvage or rebuilt brand — Oregon law makes this fraud, and brands carry forward on the title
- Seller forgets the 10-business-day Notice of Sale and gets nailed for the buyer's parking tickets
- Buyer waits past 30 days to retitle and pays late fees on top of $101
- Selling without removing your plates — Oregon plates belong to the person, not the car
- Assuming Oregon's no-tax rule applies after you move to Washington or California — those states will hit you with use tax on registration
- Skipping a DEQ pre-check before buying in Portland metro and discovering an expensive emissions failure
Pro Tip
Oregon used-car sales are about as simple and tax-friendly as anywhere in the country. Form 735-501, signed title, online Notice of Sale within 10 business days, buyer retitles within 30 days. No sales tax to chase, no smog check outside the metros.
