California Bill of Sale Requirements

Additional Forms Required in California

• REG 262 (Vehicle/Vessel Transfer and Reassignment Form) — only when the title cannot carry the odometer disclosure
• REG 138 (Notice of Transfer and Release of Liability)
• Smog Certificate

California is one of the most regulated states for private vehicle sales in the United States, with a strict 10-day title transfer window, mandatory smog certification for most vehicles, and a complex use tax calculation that includes district-level adjustments. Buyers and sellers in California must navigate a lot of paperwork.

The 10-day transfer deadline is one of the shortest in the country: the buyer must send the signed title and transfer fee to the DMV within 10 days of the sale. The DMV adds a late penalty if the transfer fee is not paid within 30 days of the transfer.

Smog certification is the most common stumbling block in California private sales. The seller is legally responsible for providing a valid smog certificate (less than 90 days old) for vehicles over 4 model years old, except in specific exempt categories. In 2026, that means vehicles from model year 2021 and older in most urban counties need a valid smog check. The seller typically pays $40-$80 for the smog inspection before listing the vehicle for sale.

California's use tax is 7.25% as a base state rate, but every county and most cities add district taxes that increase the effective rate. Los Angeles County's rate is typically 9.5%, while San Francisco is 8.625%, and parts of Alameda County can reach 10.75%. The DMV calculates tax based on the buyer's residence, not where the sale happened. Use the CA DMV's online tax calculator to estimate your exact rate.

The Release of Liability (REG 138) is perhaps the single most important document for California sellers. By filing this form online within 5 days of the sale, sellers release themselves from civil and vehicular liability for anything the buyer does with the vehicle. Without this filing, sellers have been successfully sued for accidents, tickets, and even DUIs caused by buyers who delayed their title transfers. Filing REG 138 is free, takes 2 minutes online at DMV.ca.gov, and provides significant legal protection.

REG 262 (the Vehicle/Vessel Transfer and Reassignment Form) is a secure DMV form — it cannot be downloaded, but you can get it at a DMV office or have the DMV mail it to you — and it is not notarized. The DMV uses it for the odometer disclosure when the title is noncomplying or unavailable, has an odometer error, or when the vehicle has changed hands more than once. For most private sales, REG 262 isn't needed — the signed title, with the purchase price entered on it, carries the transfer, and a bill of sale is needed only in some situations.

The Los Angeles, San Francisco, and San Diego markets dominate California's private vehicle sales. LA County alone processes over 500,000 private transfers annually, creating notorious DMV wait times that can exceed 3 hours without an appointment. Most Californians now book appointments online or use AAA offices (for members) to process title transfers, registration, and duplicate titles. Rural counties like Lake, Modoc, and Alpine process transfers within 15 minutes walk-in.

California does NOT require safety inspections. The state relies exclusively on smog certification for older vehicles and biennial registration renewal to maintain vehicle fitness standards. VIN verifications are required for out-of-state vehicles and can be performed by DMV employees, AAA offices, licensed vehicle verifiers, or California Highway Patrol officers.

Special rules apply to certain vehicle types: electric vehicles are exempt from smog but require a $100 road improvement fee at registration; motorcycles have their own exemption categories; commercial vehicles over 8,501 lbs have stricter requirements. For anyone buying or selling an unusual vehicle (RV, classic car, or imported vehicle), the CA DMV website has specific guides.

For some family-to-family transfers, California may allow a use tax exemption, claimed on Form REG 256 (Statement of Facts). Which relationships qualify is set by the DMV and CDTFA, so confirm before relying on it — a false declaration on DMV paperwork can carry penalties.
