California car registration renews every year or two, depending on your vehicle type, and you can renew online, by mail, or in person at your local DMV office.

California requires you to renew your vehicle registration before your current registration expires. The expiration date is printed on your registration card and your license plate tabs. Most passenger vehicles renew annually, though some commercial or specialty vehicles may renew on a different schedule. You do not have to wait until the expiration date to renew — you can renew up to six months early.

The California Department of Motor Vehicles (DMV) offers three main renewal routes: online through their website, by mail using the renewal notice they send you, or in person at a DMV office. Online renewal is the fastest and requires the fewest documents. Mail renewal takes longer but avoids a trip to the DMV. In-person renewal is necessary only if you cannot renew online or by mail, or if your vehicle has failed smog inspection.

Key Takeaways

  • California registration expires on the date printed on your registration card and license plate tabs, and you can renew up to six months before that date.
  • Online renewal through the DMV website is the fastest method and requires only your registration number, license plate number, and last four digits of your VIN.
  • Mail renewal uses the renewal notice the DMV sends you and takes two to three weeks; you do not need to visit an office unless your vehicle failed smog inspection.
  • Your vehicle may require a smog inspection before renewal if it is over four years old and registered in a smog-check county; the DMV renewal notice will tell you whether one is required.
  • Registration renewal fees vary by vehicle type and weight, and you can pay by credit card, debit card, or check depending on which renewal method you choose.

Renewing online through the DMV website

Online renewal is available at dmv.ca.gov and is the fastest option if your vehicle is may be able to access. You will need your registration number (found on your registration card), your license plate number, and the last four digits of your Vehicle Identification Number (VIN). The DMV website will walk you through a series of questions to confirm your vehicle information and calculate your renewal fee.

Online renewal works only if your vehicle has no outstanding violations, your registration is not suspended, and you do not owe back fees to the DMV. If any of those conditions explore, you will be directed to renew by mail or in person instead. Once you complete the online form and pay your fee by credit or debit card, you will receive a confirmation number when ready. Your new registration card and license plate tabs will arrive by mail within two to three weeks.

If you cannot find your registration number, you can look it up on the DMV website using your license plate number and VIN. This lookup tool is separate from the renewal tool and does not require you to log in.

Renewing by mail with your DMV renewal notice

The DMV mails a renewal notice to the address on file about 60 days before your registration expires. This notice includes your vehicle information, the renewal fee amount, and a payment stub. To renew by mail, sign the notice, include a check or money order for the amount shown, and mail it back to the address printed on the notice. Do not mail cash.

Mail renewal takes two to three weeks from the time the DMV receives your payment. Your new registration card and tabs will arrive separately by mail. If you do not receive a renewal notice, you can request one through the DMV website or by calling the DMV customer service line at 1-800-777-0133. Keep your current registration card and tabs until the new ones arrive.

If your vehicle requires a smog inspection before renewal, the renewal notice will state this clearly. You must have the smog inspection completed and the results submitted to the DMV before your registration can be renewed. Some smog stations can submit results electronically; others will give you a paper certificate to mail with your renewal payment.

Renewing in person at a DMV office

In-person renewal is necessary only if you cannot renew online or by mail, or if your vehicle failed a smog inspection and you need to submit proof of repair. Bring your current registration card, proof of vehicle insurance, and a valid photo ID. If your vehicle requires a smog inspection, bring the smog inspection certificate or proof that repairs have been completed.

Wait times at DMV offices vary by location and time of day. You can check current wait times for your local office on the DMV website before you go. Many DMV offices now use an online appointment system; you can reserve a time slot through the DMV website rather than arriving without an appointment. Appointments typically fill up several weeks in advance, especially near the end of the month.

If you renew in person, you can pay by cash, check, debit card, or credit card. Your new registration card will be printed on the spot, and your license plate tabs will be mailed to you within two to three weeks.

Smog inspection requirements and timing

California requires a smog inspection before registration renewal for most vehicles over four years old, with some exceptions. Vehicles registered in non-smog-check counties do not require inspection. Your renewal notice will clearly state whether a smog inspection is required for your vehicle. If it is required and you do not submit proof of inspection, your registration renewal will be denied.

Smog inspections must be performed at a Bureau of Automotive Repair (BAR) certified smog station. You can find certified stations near you through the BAR website or by searching "smog check near me." The inspection costs between $30 and $70 depending on your vehicle type and the station. If your vehicle passes, the station will submit the results to the DMV electronically or give you a paper certificate to include with your renewal payment.

If your vehicle fails the smog inspection, you have 30 days to have repairs completed and pass a second inspection. You do not need to pay for a second inspection if you return to the same station within 30 days. Once your vehicle passes, you can proceed with registration renewal.

Registration renewal fees and what they cover

California registration renewal fees are based on your vehicle's type and weight. Passenger vehicles typically cost between $250 and $350 per year, though the exact amount depends on the vehicle's age and value. Motorcycles, commercial vehicles, and specialty vehicles have different fee structures. The DMV renewal notice or online renewal tool will show you the exact fee for your vehicle before you pay.

Your registration fee covers the cost of your registration card, license plate tabs, and the DMV's administrative costs. It does not cover smog inspection fees, which are paid separately to the smog station. Some vehicles may may have access to for reduced registration fees if they are electric, hybrid, or meet other state criteria; the DMV will calculate this automatically during renewal.

If you renew early, your new registration will expire one year (or two years for some vehicle types) from the expiration date of your previous registration, not from the date you renew. This means renewing early does not extend your registration period beyond the normal cycle.

What happens if your registration expires

Driving with an expired registration is illegal in California and can result in a traffic citation. If you are stopped by law enforcement, you may receive a fine of $250 or more. Your vehicle can also be impounded if the registration is significantly overdue. If your registration has expired, renew it as soon as possible, even if you have already received a citation.

If you miss your renewal date, you can still renew through any of the three methods — online, by mail, or in person. There is no penalty for renewing late beyond the standard registration fee, though you may face traffic citations if you drive with expired registration. If your registration has been expired for more than a few months, contact the DMV to confirm your vehicle is still in good standing before attempting to renew.

Frequently Asked Questions

Can I renew my registration if my vehicle failed smog inspection?

No. You must have the vehicle repaired and pass a second smog inspection before the DMV will process your renewal. Once you have a passing smog certificate, you can renew online, by mail, or in person. The second inspection at the same station is free if you return within 30 days of the first failure.

What if I move to a different address before my registration expires?

Update your address with the DMV before you renew. You can change your address online through the DMV website, by mail, or in person at a DMV office. Use your new address when you renew your registration so the DMV sends your renewal notice and new registration card to the correct location.

Do I need to renew my license plate tabs if I renew my registration?

Yes. New license plate tabs are part of your registration renewal. The tabs show the current registration year and are required by law. They arrive by mail with your new registration card and should be placed on your license plate as soon as they arrive.

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

Registration cards and tabs typically arrive within two to three weeks of the DMV processing your renewal, whether you renew online, by mail, or in person. Continue using your current registration card and tabs until the new ones arrive. If you do not receive them within four weeks, contact the DMV.

Can I renew my registration if I have an outstanding parking ticket or traffic violation?

It depends on the type of violation. Some violations do not prevent registration renewal, while others do. If you attempt to renew online and are denied, the DMV website will tell you why. Contact the DMV or the court that issued the violation to resolve it before renewing.
