California registration is handled by the Department of Motor Vehicles, and you renew it every year or two depending on your vehicle type

California's Department of Motor Vehicles (DMV) issues vehicle registration and handles renewals through county offices and online. Your registration renewal notice arrives by mail about 60 days before your current registration expires, and you can renew online, by mail, or in person at a DMV office. The cost varies by vehicle weight and type—a standard passenger car typically costs between $200 and $300 for the first registration and less for renewals, though the exact amount depends on your vehicle's value and age.

You renew every two years for most passenger vehicles, though some commercial or specialty vehicles renew annually. Your registration expiration date is printed on your registration card and your license plate sticker. California requires you to display a current sticker on your rear license plate, and driving without one is a violation that can result in a fine.

Key Takeaways

  • California registration renewals are due every two years for most passenger vehicles, and the DMV mails you a notice 60 days before expiration.
  • You can renew online at dmv.ca.gov, by mail using the renewal notice, or in person at a county DMV office without an appointment for most renewals.
  • Renewal fees vary by vehicle weight and value but typically range from $150 to $300 for passenger cars, and you pay once every two years.
  • Your vehicle must pass a smog check before you renew if it is subject to California's emissions testing program, and the DMV will not process your renewal without proof.
  • If your registration has expired, you can still renew it, but driving with an expired registration is illegal and can result in a citation and fine.

What information and documents you need to renew

Before you start a renewal, gather your current registration card, proof of insurance, and your vehicle identification number (VIN). The renewal notice the DMV mails you contains most of the information already filled in, which speeds up the process whether you renew online or by mail.

If your vehicle address, ownership, or lien holder has changed since your last registration, you will need to provide updated information. A change of address can be done during renewal, but a change of ownership requires a new registration process rather than a renewal. If someone else holds a lien on your vehicle (such as a bank or finance company), their name must appear on your registration, and you will need their written consent to remove them.

California also requires proof of a smog check for most vehicles before renewal. Vehicles that are four model years old or newer, diesel vehicles under 14,000 pounds, and vehicles registered in certain counties are exempt. If your vehicle is subject to smog testing, you must have the test completed and the certificate in hand before the DMV will process your renewal.

Renewing online through dmv.ca.gov

Online renewal is the fastest option and requires no visit to an office. Go to dmv.ca.gov, select "Renew Your Registration," and enter your license plate number and date of birth. The system will pull up your registration record and show you the renewal fee. You can pay by credit card, debit card, or electronic check.

Online renewal works only if your registration information has not changed and your vehicle does not require a smog check, or if you already have a passing smog certificate. If the system tells you that you cannot renew online, it means your record requires a staff member to review it—usually because of an address change, ownership change, or missing smog documentation. In that case, you can renew by mail or in person instead.

After you pay online, the DMV mails your new registration card and license plate sticker within two to three weeks. You can drive legally during this time as long as your old sticker is still valid. Once the new sticker arrives, remove the old one and explore the new one to your rear license plate.

Renewing by mail using your renewal notice

If you received a renewal notice in the mail, you can send it back with payment and any required documents. Fill out the notice, include your smog certificate if required, and mail it with a check or money order to the address printed on the notice. Do not send cash through the mail.

Mail renewal takes longer than online—typically three to four weeks for processing plus mail delivery time. Send your renewal at least four weeks before your registration expires to avoid driving with an expired registration. Keep a copy of what you send for your records, and consider using certified mail if you want proof of delivery.

If your renewal notice was lost or you did not receive one, you can still renew by mail by downloading the renewal form from dmv.ca.gov or calling your county DMV office to request one. The process is the same: fill it out, include payment and required documents, and mail it in.

Renewing in person at a DMV office

You can walk into any California DMV county office during business hours and renew your registration without an appointment for most standard renewals. Bring your renewal notice (if you have it), your current registration card, proof of insurance, and your smog certificate if required. Have your payment method ready—DMV offices accept cash, check, credit card, and debit card.

Processing times at the office vary by location and time of day. Offices are typically less busy early in the morning on weekdays and more crowded on Fridays and near the end of the month. You will receive your new registration card and license plate sticker on the spot if everything is in order.

If you need to make changes to your registration—such as updating your address or adding a new owner—staff can help you during your visit. However, if your vehicle requires a smog check and you do not have the certificate with you, you will need to complete the test first and return with proof before the DMV can finalize your renewal.

Understanding smog check requirements and exemptions

California requires a smog check (also called an emissions test) before registration renewal for most vehicles, though some are exempt. Vehicles that are four model years old or newer do not require a smog check. Diesel vehicles under 14,000 pounds require a smog check every two years. Gasoline vehicles older than four model years require a check every two years.

Some counties have different rules. If you live in a county with a smog check exemption program, your vehicle may not need testing even if it is older. Check dmv.ca.gov or call your county DMV to confirm whether your specific vehicle requires a test.

You must have the smog check completed before you renew your registration. The testing station provides a certificate with the results, and you submit that certificate to the DMV along with your renewal. If your vehicle fails the smog check, you have 30 days to repair it and retest. The DMV will not process your renewal until you provide a passing certificate.

What happens if your registration expires

Driving with an expired registration is illegal in California. If you are stopped by law enforcement, you can receive a citation and fine. The fine for an expired registration typically ranges from $100 to $250, depending on how long it has been expired and whether you have prior violations.

You can renew an expired registration at any time—there is no grace period, but there is also no penalty for renewing late beyond the standard renewal fee. However, you should not drive the vehicle on public roads until your renewal is processed and your new sticker is displayed. If you need to drive it to a DMV office or testing station, you are taking a legal risk.

If your registration has been expired for more than a few months, the DMV may require you to pass a smog check even if your vehicle would normally be exempt. This is to may support that vehicles that have been off the road are still safe and compliant before they return to regular use.

Frequently Asked Questions

Can I renew my registration if my vehicle has a lien on it?

Yes, you can renew as long as the lien holder is listed on your registration. The DMV will not remove a lien holder without their written consent. If you have paid off the loan, contact your lender for a lien release document, then submit it to the DMV to update your registration.

What if I move out of state but still own a California-registered vehicle?

You must register your vehicle in your new state within a certain timeframe (usually 10 to 30 days, depending on the state). You cannot renew a California registration if you are no longer a California resident. Contact your new state's DMV for registration requirements.

How long does it take to receive my new registration card and sticker after I renew online?

The DMV typically mails your new card and sticker within two to three weeks of processing your online renewal. You can drive legally with your old sticker until the new one arrives. If you do not receive them within four weeks, contact the DMV to check the status of your renewal.

Do I need to renew my registration if I sell my vehicle?

No. When you sell your vehicle, the new owner registers it in their name. You should notify the DMV of the sale by submitting a Notice of Transfer and Release of Liability form to protect yourself from liability for the vehicle after the sale.

What if my smog check fails?

You have 30 days to repair your vehicle and retest at any smog station. Once it passes, you receive a new certificate and can submit it to the DMV to complete your renewal. If you cannot repair the vehicle within 30 days, you can request a second 30-day extension from the original testing station.
