What California registration requires and how to renew it

California vehicle registration is a yearly renewal you handle through the Department of Motor Vehicles (DMV). When you renew, you pay a registration fee based on your vehicle's value, and the DMV issues you a new registration card and license plate tabs (the stickers that go on your plate). You can renew online, by mail, or in person at a DMV office, and most people renew 30 to 60 days before their expiration date to avoid late fees.

The registration card — officially called your Certificate of Registration — proves you own the vehicle and have paid the state fee. Your license plate tabs show the current year and month your registration expires. Both documents must be in the car while you drive. If you let registration lapse, you cannot legally drive the vehicle, and you risk a citation if stopped by law enforcement.

Key Takeaways

  • California registration renews every year on the month and date shown on your current registration card, and you can renew online starting 60 days before expiration.
  • The registration fee depends on your vehicle's market value, which the DMV calculates using a formula based on the model year and condition — not what you paid for it.
  • You need your current registration card, proof of a passing smog check (for most vehicles), and proof of California insurance to renew.
  • Late renewal adds a penalty fee on top of your regular registration cost, and driving with expired registration can result in a traffic citation.
  • If you sell your vehicle, you must notify the DMV within 5 days to avoid liability for tickets or violations the new owner incurs.

How the registration fee is calculated

Your registration fee is not a flat amount — it depends on what the DMV calls the "market value" of your vehicle. The DMV uses a formula based on your vehicle's model year, make, model, and condition to estimate what it would sell for. This is different from what you paid for it or what you think it is worth. The older the vehicle, the lower the market value, and the lower your fee.

The DMV publishes a schedule each year showing the base fee for each vehicle type and model year. For example, a 2023 sedan might have a higher base market value than a 2015 sedan of the same make. You can look up your vehicle's estimated market value on the DMV website before you renew, so you know roughly what to expect. If you believe the DMV's valuation is wrong, you can request a review, though this is uncommon and requires documentation of the vehicle's actual condition.

Documents you need to renew registration

To renew your California registration, you need three things: your current registration card, proof of a passing smog inspection, and proof of California auto insurance. The registration card is the document the DMV sent you when you last renewed — it shows your vehicle identification number (VIN), license plate number, and expiration date.

The smog check requirement applies to most vehicles registered in California, though there are exceptions. Vehicles that are model year 1975 or older, electric vehicles, and vehicles registered for the first time in California are exempt. For all other vehicles, you must pass a smog inspection within 90 days before you renew. You take your vehicle to a smog station (a licensed testing facility), pay a testing fee, and receive a certificate if it passes. If it fails, you must repair the vehicle and retest.

Proof of insurance means a current California auto insurance policy. The DMV verifies your insurance electronically when you renew online or in person, so you do not need to bring a physical document — but you must have active coverage. If your insurance lapses between renewals, you cannot legally drive the vehicle.

Renewing online, by mail, or in person

The fastest way to renew is online through the DMV website. You can start renewing 60 days before your expiration date. You will need your registration card, the last four digits of your vehicle identification number (VIN), and your date of birth. The DMV will verify your insurance electronically. If your vehicle requires a smog check and you have not yet passed one, the online system will tell you and you cannot complete the renewal until you do. Once you submit, you pay the fee by credit or debit card, and the DMV mails your new registration card and tabs within two weeks.

If you renew by mail, you fill out form REG 14 (available on the DMV website), include your current registration card, proof of a passing smog check, and a check or money order for the fee. Mail it to the address shown on the form. Processing takes longer by mail — typically three to four weeks — so send it well before your expiration date.

In-person renewal at a DMV office is an option if you prefer to handle it face-to-face, but it requires an appointment. You can book an appointment on the DMV website. Bring your registration card, proof of smog (if required), and proof of insurance. You will pay at the counter and receive your new tabs when ready, though your registration card arrives by mail.

What happens if your registration expires

If you drive with expired registration, you can receive a traffic citation. The fine varies, but it is typically $100 to $250 for a first offense. More importantly, you cannot legally operate the vehicle on public roads. If you are stopped by law enforcement, the officer can cite you and may impound the vehicle depending on how long it has been expired.

If you realize your registration has expired, renew it as soon as possible. You can renew online or in person even after the expiration date. You will owe the regular registration fee plus a late penalty fee. The penalty is typically $50 to $100 depending on how long the registration has been expired. Once you renew, you are legal to drive again, though the citation you received (if any) is a separate matter handled through traffic court.

Transferring registration when you sell your vehicle

When you sell your vehicle in California, you must notify the DMV within 5 days. You do this by submitting form REG 138 (Notice of Transfer and Release of Liability) either online through the DMV website or by mail. This form tells the state that you no longer own the vehicle and releases you from liability for any traffic violations, parking tickets, or accidents the new owner causes.

If you do not submit this form, you remain the registered owner on the DMV's records. This means you could be held responsible for violations the new owner incurs, and you may receive notices or citations in the mail. The new owner must register the vehicle in their name within 10 days of purchase, but that does not automatically remove you from the title. Submitting the release of liability form is your protection.

Registration for new California residents and out-of-state vehicles

If you move to California from another state, you must register your vehicle with the California DMV within 20 days of establishing residency. You will need your out-of-state title or registration, proof of California insurance, and a passing smog check (unless your vehicle is exempt). The registration fee is based on the same market value formula as any other vehicle. Your out-of-state plates are no longer valid once you register in California, and you must replace them with California plates.

If you are a California resident but have not yet registered a vehicle you own, the process is similar. You need the title, proof of insurance, and a smog check. The DMV will issue you a new registration card and plates. First-time registrations do not require a smog check, so you can complete the registration without that step.

Frequently Asked Questions

Can I renew my registration if my smog check failed?

No. You must repair the vehicle and pass the smog test before you can renew. Once you have a passing certificate, you can complete your registration renewal. If your registration expires while you are waiting for repairs, you cannot legally drive the vehicle.

What if I move to a different county in California?

You do not need to re-register your vehicle. Your registration is valid statewide regardless of which county you live in. You only need to update your address with the DMV if your registration card shows an old address. You can do this online or by mail using form DL 43.

Do I have to renew in person if I have a disability?

No. You can renew online or by mail. If you need information at a DMV office, you can request an accommodation when you book your appointment. The DMV also offers a disabled person placard or license plate if your vehicle is used to transport someone with a mobility disability.

What if my registration card is lost or damaged?

You can request a replacement registration card from the DMV online or in person. There is a small fee, typically $5 to $10. You will need your VIN and date of birth. A replacement arrives by mail within two weeks. Until it arrives, you should carry proof of your current registration if you drive.

Can I register a vehicle that does not have a valid title?

No. You must have a valid title to register a vehicle in California. If you lost your title, you can request a duplicate from the DMV. If the vehicle was never titled in California, you will need the out-of-state title or a bill of sale and proof of ownership. The DMV can guide you through this process.
