What you need to do to register a car in California

California registration happens through the Department of Motor Vehicles (DMV), and you must complete it before you can legally drive the car on public roads. The process differs depending on whether you are registering a new car, a used car you just bought, or a vehicle you moved to California from another state. In all cases, you will need proof of ownership, proof of California residency, and payment of the registration fee—which varies based on the vehicle's value and type.

You can register online through the DMV website for some transactions, by mail, or in person at a DMV office. The fastest route for most people is online registration if your vehicle qualifies, followed by mail-in registration. In-person visits are necessary only if the DMV cannot process your process remotely or if you need to handle other services at the same time.

Key Takeaways

  • California requires registration before you drive, and the DMV processes all registrations through its website, by mail, or at local offices.
  • You will need the vehicle's title or proof of ownership, a California ID or proof of residency, and payment for the registration fee, which depends on the car's value.
  • New residents have 20 days from establishing residency to register an out-of-state vehicle in California.
  • Registration fees include the base fee plus an additional vehicle license fee calculated from the vehicle's value; the total is not a flat amount.
  • You can renew registration online or by mail before your current registration expires, and the DMV sends renewal notices 60 days before expiration.

Documents you will need to bring or submit

The exact documents depend on your situation, but the core set is the same: proof of ownership, proof of California residency, and proof of identity. For a new car purchase, you will have a manufacturer's certificate of origin or a bill of sale from the dealer. For a used car, you need the title signed over to you by the previous owner. If you are registering an out-of-state vehicle, you need the title from that state plus proof that you now live in California.

Proof of California residency can be a utility bill, lease agreement, mortgage statement, or government mail showing your current address. Your driver's license serves as both identity and residency proof if it shows your California address. If you do not have a California ID yet, bring a passport or out-of-state ID plus a separate residency document. Some transactions also require a smog check certificate, which is mandatory for vehicles over four model years old unless they are electric or meet other exemptions.

If someone else is registering the vehicle on your behalf, you will need a signed power of attorney form (DMV Form REG 260) authorizing that person to act for you. Keep copies of everything you submit, whether you register online, by mail, or in person.

Registration fees and how they are calculated

California registration is not a flat fee. The total cost includes a base registration fee plus a vehicle license fee (VLF) calculated from the vehicle's market value. The base fee is currently $65.25 for most passenger vehicles, but the VLF varies. For a new vehicle, the VLF is 11 percent of the manufacturer's suggested retail price (MSRP) in the first year, then decreases each year. For a used vehicle, the VLF is based on the market value determined by the DMV.

You can estimate your registration cost using the DMV's online fee calculator, which asks for your vehicle type, year, and purchase price. The calculator shows both the base fee and the VLF so you know the total before you submit. If you are registering an out-of-state vehicle, you may owe back fees for the time you owned it in California before registering it, though this is waived if you register within 20 days of establishing residency.

Payment methods vary by registration method. Online registration accepts credit and debit cards. Mail-in registration accepts checks or money orders. In-person registration at a DMV office accepts cash, checks, debit cards, and credit cards.

Registering a new vehicle from a dealer

When you buy a new car from a California dealer, the dealer often handles the registration paperwork on your behalf as part of the sale. You will sign the process (DMV Form REG 343) at the dealership, and the dealer submits it to the DMV. You still pay the registration fee, usually rolled into your final bill. The dealer will give you a temporary registration document valid for 90 days while the DMV processes the permanent registration.

Check with your dealer about what they are handling and what you need to do. Some dealers complete the full registration; others submit only the initial paperwork and ask you to finish the process online or by mail. Ask for a copy of the submitted process so you have a record of what was filed. If the dealer does not complete registration within 30 days, you can finish it yourself online or by mail using the same documents the dealer would have used.

Registering a used vehicle you purchased privately or from a dealer

If you buy a used car from a private seller or a used-car dealer, you are responsible for registering it. You have 10 days from the purchase date to register the vehicle in California. Start by getting the title signed over to you by the seller—this is the most critical step, because without a signed title, the DMV cannot process your registration.

Once you have the signed title, you can register online through the DMV website if the title is in your name and you have all required documents. If the title has liens or is held by a lender, you may need to submit additional paperwork showing the lien holder's consent. For a used vehicle, you will also need a smog check certificate unless the vehicle is exempt (electric vehicles, vehicles under four model years old, and some others are exempt). The smog check must be completed within 90 days before you register.

If you cannot register online, you can mail the process and documents to the DMV or visit a local office in person. Processing time by mail is typically 4 to 6 weeks. Online registration is faster—you receive your registration documents within 2 to 3 weeks in most cases.

Registering an out-of-state vehicle when you move to California

If you move to California and bring a vehicle registered in another state, you must register it in California within 20 days of establishing residency. Establishing residency means you have a California address, a California job, or enroll in a California school—the DMV uses these as markers. If you register within 20 days, you do not owe back registration fees for the time you owned the vehicle before registering it.

To register an out-of-state vehicle, you need the out-of-state title, proof of California residency, and a smog check certificate (unless exempt). Some states' titles are not accepted by California; if your title is from a state that does not issue titles for older vehicles or has a non-standard format, contact the DMV before you register to confirm what documents you will need. You can start the registration process online, by mail, or in person at a DMV office.

If you miss the 20-day window, you still must register the vehicle before driving it on California roads. You will owe penalties and back registration fees, so registering as soon as possible after moving is important for cost and legal reasons.

Renewing your registration before it expires

California registration is valid for one or two years depending on the vehicle type and when you registered it. The DMV sends a renewal notice 60 days before your registration expires, showing the renewal fee and your options. You can renew online through the DMV website, by mail, or in person at a DMV office. Online renewal is the fastest and most convenient for most people.

To renew online, you need your registration renewal notice, your vehicle identification number (VIN), and a payment method. The DMV website will ask you to confirm your vehicle information and residency. If your address has changed, update it during renewal. If you have not received a renewal notice 60 days before expiration, you can still renew online or by mail using your registration documents.

Do not wait until your registration expires to renew. Driving with expired registration is a violation, and you can be cited by law enforcement. If your registration has already expired, you can still renew, but you may face penalties. Renew as soon as you notice the expiration date approaching.

What happens if you register late or do not register

Driving without current registration is illegal in California. If you are stopped by law enforcement, you can be cited and fined. The fine for driving with expired registration starts at $100 and increases if the registration has been expired for more than six months. Additionally, if you are in an accident and your registration is not current, your insurance may deny coverage, leaving you liable for damages.

If you buy a used vehicle and do not register it within 10 days, you are driving illegally and risk citation. If you move to California and do not register an out-of-state vehicle within 20 days, you owe back registration fees plus penalties. The longer you wait, the higher the total cost. Register as soon as your documents are ready to avoid these consequences.

If you have already missed a important date, register when ready. The DMV will calculate any back fees owed, but registering stops the accumulation of additional penalties. Contact the DMV or visit a local office if you are unsure about your registration status or what you owe.

Frequently Asked Questions

Can I register my car online if I just moved to California from another state?

Yes, if you have an out-of-state title and a smog check certificate. Start the registration on the DMV website and follow the prompts for out-of-state vehicles. You will need to upload or mail the title and smog certificate. If the DMV cannot process your process online, it will tell you what to do next.

What if the previous owner did not sign the title over to me?

You cannot register the vehicle without a signed title. Contact the previous owner and ask them to sign the title and send it to you. If they refuse or are unreachable, you may need to pursue a legal remedy through small claims court or contact the DMV for guidance on your specific situation.

Do I need a smog check to register a new car?

No. New vehicles are exempt from smog checks for their first registration. Used vehicles over four model years old require a smog check unless they are electric or meet other exemptions. Check the DMV website to confirm whether your specific vehicle is exempt.

How long does registration take if I explore by mail?

Mail-in registration typically takes 4 to 6 weeks from the time the DMV receives your process. Online registration is faster, usually 2 to 3 weeks. In-person registration at a DMV office can be completed the same day, though wait times vary by location.

What if I move to a different address after I register?

Update your address with the DMV as soon as you move. You can do this online, by mail, or in person. Updating your address does not require a new registration; it updates your existing registration record. The DMV will send future renewal notices to your new address.
