What you need to register a car in California
California requires you to register your vehicle within 20 days of purchase or moving to the state. You will need to submit an process for Title or Registration (Form REG 343) along with proof of ownership, proof of California residency, and a smog certification (for most vehicles). The California Department of Motor Vehicles processes registrations through its field offices, by mail, or online through its website.
The exact documents you bring depend on whether you are registering a new purchase, a vehicle you own outright, or one with a loan or lease. A dealer typically handles registration for new car purchases, but you still receive the paperwork and bill of sale to keep. If you bought used, you will need the title signed by the previous owner, a bill of sale, and your proof of residency.
Registration fees in California are based on the vehicle's value and weight. The base fee starts around $65, but the total can reach $200 to $300 or more depending on your vehicle type and local taxes. You will also pay a one-time smog certification fee if your vehicle requires testing.

Registering a new car purchase from a dealer
When you buy a new car from a California dealer, the dealer usually handles the registration paperwork on your behalf. You will sign the title process and provide your driver's license and proof of residency. The dealer submits the paperwork to the DMV and collects the registration fee from you at the time of sale.
The dealer will give you a temporary registration document (usually valid for 90 days) so you can drive the vehicle home and to the DMV office if needed. Your permanent registration card arrives by mail within two to three weeks. Keep the temporary document in your vehicle until the permanent one arrives.
If the dealer does not handle registration or you prefer to do it yourself, you can submit Form REG 343 directly to the DMV with your proof of ownership and residency. This is less common but may happen if you buy from a private party or a dealer outside California.
Registering a used car you purchased privately
When you buy a used car from a private seller, you are responsible for completing the registration. You will need the title signed by the seller, a bill of sale (Form REG 135 or a written agreement showing the sale price and date), your proof of California residency, and your driver's license.
Before you register, you must obtain a smog certification from a Bureau of Automotive Repair-certified smog station. Most vehicles registered in California require this test. Vehicles model year 1975 and older, electric vehicles, and some newer low-emission vehicles are exempt. The smog test costs between $30 and $70 and is valid for 90 days.
Once you have all documents, you can register online through the California DMV website, by mail, or in person at a field office. Online registration is the fastest option if your vehicle meets the requirements (no liens, no out-of-state title transfer needed). By mail typically takes two to three weeks. In-person registration at a field office can be completed the same day, though wait times vary by location.
Smog certification requirements and exemptions
California requires a smog certification for most vehicles before registration. The test checks your vehicle's emissions to may support it meets state air quality standards. You must pass the test before you can complete registration, and the certification is valid for 90 days from the test date.
Vehicles exempt from smog testing include those model year 1975 and older, all-electric vehicles, vehicles with a model year four years newer than the current year, and some low-emission vehicles certified by the California Air Resources Board. Diesel vehicles have different testing requirements than gasoline vehicles. If you are unsure whether your vehicle needs testing, the smog station can tell you based on your vehicle's year and type.
If your vehicle fails the smog test, you have 30 days to repair it and retest at no additional charge. If it fails again, you may be able to register it under California's Smog Check information Program if your vehicle is at least 16 years old and you meet income requirements, though this is a limited program with specific rules.
Registration fees and payment methods
California registration fees are calculated based on your vehicle's market value and weight. The base registration fee is approximately $65, but the total bill includes a vehicle license fee (based on value), county fees, and any local taxes. For a vehicle worth $20,000, you might pay $150 to $250 total. For a vehicle worth $50,000 or more, fees can exceed $400.
You can pay registration fees in person at a DMV field office, by mail with your process, or online through the California DMV website. Payment methods include cash, check, money order, credit card, or debit card. If you register by mail, include a check or money order with your process. Online payment requires a credit or debit card.
If you register late (after 20 days), you will owe a late fee in addition to the standard registration fee. The penalty increases the longer you wait, so registering as soon as possible after purchase or moving to California saves money.
Registering a financed or leased vehicle
If you financed your vehicle through a loan, the lender holds the title until you pay off the loan. You will still register the vehicle in your name, but the lender's name appears on the title as the lienholder. You can register the vehicle when ready after purchase; you do not have to wait until the loan is paid off.
When you register a financed vehicle, provide the dealer's paperwork showing the lender's information, your proof of residency, and your driver's license. The DMV records the lender's interest in the vehicle. Once you pay off the loan, the lender sends you the title free and clear, and you can request a new registration card if needed.
Leased vehicles follow a similar process. The leasing company holds the title, and you register the vehicle in your name with the lessor listed as the lienholder. You are responsible for registration, smog testing, and insurance during the lease term. When the lease ends, you return the vehicle to the leasing company, and they handle the title transfer.
Where and how to register your vehicle
You can register your vehicle at any California DMV field office, by mail, or online through the California DMV website. Online registration is available for most standard registrations and is the fastest option. You will need to create an account on the DMV website, upload your documents, and pay the fee by credit or debit card. Processing typically takes five to ten business days.
To register by mail, complete Form REG 343, include all required documents and a check or money order, and send the packet to the address listed on the form. Mail processing takes two to three weeks. Include a self-addressed stamped envelope if you want your documents returned.
In-person registration at a DMV field office allows you to complete the process the same day. Bring your completed Form REG 343, title, proof of residency, proof of ownership, smog certification, and payment. Arrive early or use the DMV's online appointment system to reserve a time slot and reduce wait time. Not all field offices offer all services, so check the DMV website to confirm your local office handles vehicle registration.
