What California car registration requires and costs

California requires you to register your vehicle with the Department of Motor Vehicles (DMV) within 20 days of purchase or moving to the state. Registration is not optional — driving an unregistered car is illegal and can result in fines, impoundment, and citations.

The registration fee depends on the vehicle's value. California uses a formula based on the manufacturer's base price, not what you paid. For most vehicles, the fee ranges from roughly $250 to $350 annually, though luxury vehicles and those with high base prices can cost significantly more. You also pay a one-time registration fee when you first register the car in California, which is separate from the annual renewal fee.

You will need proof of ownership (the title or bill of sale), proof of California residency, proof of insurance, and a completed process for Registration (Form REG 343). If you are financing the vehicle, the lender's name appears on the title until the loan is paid off.

Key Takeaways

  • California registration must happen within 20 days of purchase or moving to the state, and the DMV enforces this important date with fines and vehicle impoundment.
  • Registration fees are based on the manufacturer's base price, not the price you paid, and renewal happens annually on your birthday month or the month you first registered.
  • You need the title or bill of sale, proof of California residency, proof of insurance, and a completed registration form to register at the DMV.
  • If you register online through the DMV website, you can renew without visiting an office, though new registrations typically require an in-person visit or mail submission.
  • Smog checks are required for most vehicles over four years old before registration, and the DMV will not issue plates without proof of a passing test.

How to register a new vehicle in California

If you bought a car in California, the dealer usually handles the paperwork and sends it to the DMV on your behalf. You receive temporary registration documents and a temporary license plate. The permanent registration and plates arrive by mail within two to three weeks. Do not drive without the temporary documents — they are your proof of registration during this period.

If you bought the car out of state or from a private seller, you must register it yourself. Visit a DMV office or submit your documents by mail. Bring the title (signed by the seller), a bill of sale if you have one, proof of California residency (a utility bill, lease, or mortgage statement dated within 90 days), your driver's license, and proof of insurance. Complete Form REG 343 before you go.

The DMV will inspect the vehicle's Vehicle Identification Number (VIN) to confirm it matches the title. This inspection is free and takes a few minutes. After inspection and payment, you receive temporary registration and plates on the spot. Permanent plates arrive by mail.

Smog checks and registration timing

California requires a smog check (also called an emissions test) for most vehicles before you can register them. The vehicle must be at least four years old and cannot be a zero-emission vehicle like a Tesla. You must pass the smog check before submitting your registration paperwork to the DMV — the DMV will not issue plates without proof of a passing test.

Find a smog station near you through the DMV website. The test costs between $30 and $80 depending on the station and vehicle type. Bring your keys and proof of ownership. The test takes 10 to 30 minutes. If you pass, the station gives you a certificate of compliance. If you fail, you have 30 days to repair the vehicle and retest at no additional cost at the same station.

Smog checks are also required every two years when you renew your registration, unless your vehicle is exempt. Vehicles from 1975 and earlier, and some newer zero-emission vehicles, do not need smog checks. Ask the smog station or check the DMV website to confirm whether your vehicle is exempt.

Renewing your California registration

Your registration renews on your birthday month each year, or on the anniversary of the month you first registered the vehicle if you registered it mid-year. The DMV sends a renewal notice 60 days before your renewal date. You can renew online through the DMV website if you have no changes to your vehicle or address, no outstanding violations, and your vehicle is not over 10 years old.

Online renewal takes about 10 minutes and costs the same as in-person renewal. You pay the registration fee and any applicable smog check fee. If your vehicle requires a smog check, you must complete it before renewing online — the DMV will not process your renewal without proof of a passing test.

If you cannot renew online, visit a DMV office or mail your renewal notice with payment. Bring your current registration card and proof of insurance. If your address has changed, bring proof of your new California residency. Do not let your registration expire — driving with expired plates is illegal and can result in fines.

Transferring registration when you move or sell

If you move to another state, you must register your vehicle in that state within the timeframe it requires — usually 30 to 90 days. You can cancel your California registration by notifying the DMV in writing or through the DMV website. You do not need to return your plates, but you can if you want.

If you sell your vehicle, the new owner must register it in their name. You should notify the DMV of the sale to avoid liability for traffic violations or accidents involving the car after you no longer own it. Complete the Notice of Transfer and Release of Liability (Form REG 138) and submit it to the DMV by mail or online. Keep a copy for your records.

The buyer is responsible for registering the vehicle in their name. If they do not register it within 20 days, you may receive notices or citations. Submitting Form REG 138 protects you by establishing that you are no longer the owner.

Special registration situations in California

If you own a vehicle with a salvage title (one that was declared a total loss by an insurance company), you can register it in California only after it passes a Department of Highway Patrol inspection and is issued a rebuilt title. The inspection confirms the vehicle is safe and the damage has been properly repaired. This process takes several weeks and costs additional fees beyond standard registration.

If you own a vehicle registered to a business or trust, the registration is issued in that entity's name. You will need the business license or trust documents when you register. If the business or trust changes, you must update the registration within 10 days.

Vehicles used for commercial purposes (like rideshare or delivery) may require different registration or additional endorsements. Check with the DMV if your vehicle is used for business to confirm you have the correct registration type.

Common registration mistakes and how to avoid them

The most common mistake is missing the 20-day registration important date. If you drive without registering, you face fines starting at $250 and risk impoundment. If you bought a car and the dealer did not submit the paperwork, contact them when ready. If you bought from a private seller, register within the important date yourself.

Another frequent error is not updating your address with the DMV when you move within California. Your registration remains valid, but the DMV sends renewal notices to your old address, which can cause you to miss the renewal important date. Update your address online through the DMV website or at any DMV office.

Failing to get a smog check before registration is also common. The DMV will not issue plates without proof of a passing test, so plan for the smog check before you go to register. If your vehicle fails, budget time for repairs and a retest.

Frequently Asked Questions

Can I register a car in California if I do not have a California driver's license?

Yes. You need proof of California residency (such as a utility bill or lease) and a valid ID from any state or country, but you do not need a California driver's license. If you are a new resident, you have 10 days to obtain a California license, but you can register your vehicle before that.

What happens if I let my registration expire?

Driving with expired registration is illegal and can result in fines of $250 or more. If you are stopped by law enforcement, you may also receive a citation. Renew your registration before your renewal date by using the online system, visiting a DMV office, or mailing your renewal notice.

Do I need to register a vehicle I am not driving?

If the vehicle is on public roads or parked on public property, yes — it must be registered. If it is stored on private property and not driven, you can request a non-operational registration, which costs less and does not require a smog check. Contact the DMV for details on non-operational registration.

How long does it take to get permanent registration plates after I register?

Permanent plates typically arrive by mail within two to three weeks of registration. You receive temporary registration and plates when ready when you register at a DMV office. Do not remove the temporary plates until the permanent ones arrive.

What if my vehicle title has a lien on it?

You can still register the vehicle. The lender's name appears on the title and registration until the loan is paid off. Once you pay off the loan, the lender releases the lien, and you can request a clean title from the DMV showing you as the sole owner.
