What you need to do to register an out-of-state vehicle in California

When you move to California or buy a car registered in another state, you must register it with the California Department of Motor Vehicles (DMV) within 20 days of establishing residency or taking ownership. California does not allow you to keep an out-of-state registration once you become a resident. The process requires an in-person visit to a DMV office, a smog inspection for most vehicles, and payment of registration fees that are typically higher than renewal fees for vehicles already registered in the state.

You cannot straightforward transfer your existing registration. The DMV treats this as a new registration, which means you will pay the full registration fee based on your vehicle's value, not just a renewal amount. The exact cost depends on the vehicle's age, type, and assessed value.

Key Takeaways

  • You have 20 days from becoming a California resident to register your out-of-state vehicle with the DMV.
  • Most vehicles must pass a smog inspection before the DMV will process registration, and you pay for this inspection separately.
  • Bring your out-of-state title, proof of California residency, proof of insurance, and a completed process for Title or Registration (Form REG 343).
  • Registration fees for a new registration are based on your vehicle's value and are higher than annual renewal fees.
  • You can start the process online through the DMV website, but you must complete it in person at a DMV office.

Documents you need to bring to the DMV

Gather these documents before you visit a DMV office. You will need your original out-of-state title or a certified copy. If the title is held by a lender, you may be able to proceed, but contact your local DMV office first to confirm what they accept. Bring proof of California residency dated within the last 60 days — a utility bill, lease agreement, mortgage statement, or government mail with your name and current address all work.

You also need proof of insurance showing California coverage. Your out-of-state policy may not be valid in California, so contact your insurance company before your DMV visit to confirm you have active California coverage. Bring the insurance card or a declaration page from your insurer. Finally, complete Form REG 343 (process for Title or Registration), which you can read from the DMV website or fill out at the office.

If you are registering a vehicle with a lien (the lender holds the title), bring documentation from the lender showing they consent to the transfer. If the vehicle was recently purchased, bring the bill of sale or purchase agreement.

The smog inspection requirement and exemptions

California requires a smog inspection for most vehicles before registration. The vehicle must be at least four model years old to require a smog test. Vehicles that are three years old or newer are exempt. You must pass the inspection before submitting your registration to the DMV — the inspection facility provides a certificate that you bring to the DMV office.

A few vehicle types are exempt from smog testing: electric vehicles, vehicles with a manufacturer's certificate of non-operation, and some vehicles registered as classic cars or street rods. If your vehicle qualifies for an exemption, you will still need to document this at the DMV. Smog inspections cost between $30 and $70 depending on the testing station, and this fee is separate from registration fees.

Find a smog station near you through the DMV's online locator tool. Make an appointment or walk in — most stations can test your vehicle the same day. The inspection takes about 30 minutes.

Registration fees and how they are calculated

Registration fees for an out-of-state vehicle are based on the vehicle's assessed value, not the price you paid. The DMV uses a formula that depreciates the vehicle's value each year. A newer vehicle or one with a higher original value will have higher registration fees. For example, a five-year-old sedan might cost $200 to $400 to register, while a newer luxury vehicle could cost $600 or more.

You also pay a one-time title fee (currently around $15) and a registration process fee (currently around $70). Some vehicles require additional fees — commercial vehicles, trailers, and motorcycles have different fee structures. The DMV website has a fee calculator where you can enter your vehicle information to see an estimate before you visit.

Payment is due at the time of registration. The DMV accepts cash, check, debit card, and credit card. If you cannot pay the full amount at once, contact your local DMV office to ask about payment plans, though these are not always available.

Steps to register your vehicle in person

Start by scheduling an appointment through the DMV's online system or by calling your local office. Walk-ins are accepted but often have long wait times. Bring all documents listed above, your vehicle keys, and your out-of-state license plates.

At the DMV office, a clerk will review your documents, verify your smog inspection certificate, and calculate your registration fees. They will take your out-of-state plates and issue California plates on the spot or mail them to you within two weeks. You will receive a registration card (proof of registration) when ready. Your vehicle is legally registered once you leave the DMV office, even if your plates arrive by mail.

The entire process typically takes 30 to 60 minutes at the office, though this varies by location and how busy the office is. If documents are missing or incomplete, the DMV will tell you what you need to bring back.

What happens if you miss the 20-day important date

If you do not register your vehicle within 20 days of becoming a California resident, you can still register it, but you may face a late registration penalty in addition to your regular fees. The penalty is typically a percentage of your registration fee, though the exact amount varies. You are also driving illegally during that time, which can result in a traffic citation if you are stopped by law enforcement.

Register as soon as possible after the important date passes. The DMV will calculate any penalties owed when you submit your registration. There is no grace period or forgiveness for late registration — the penalty applies automatically.

Registering a vehicle with an out-of-state lien or loan

If your vehicle has an outstanding loan and the lender holds the title, you can still register it in California. Contact your lender and ask them to send a lien release letter or consent form to you, or ask whether they will send it directly to the California DMV. Some lenders can do this electronically; others require a paper form.

Bring this document to the DMV along with your other paperwork. The DMV will note the lien on your California registration if the lender requests it. Once you pay off the loan, the lender will send you the title, and you can update your registration to remove the lien notation. This update is free and can be done by mail or at a DMV office.

Frequently Asked Questions

Can I register my out-of-state car online without going to the DMV?

No. You must visit a DMV office in person to register an out-of-state vehicle. You can start the process online by creating an account and gathering information, but the final registration must be completed at a physical DMV location with your documents and payment.

What if my out-of-state title has a lien on it and I cannot contact the lender?

Contact your local DMV office and explain the situation. They may be able to help you locate the lender or advise you on alternative steps. In some cases, you may need to resolve the lien before registration can proceed. Do not attempt to register without addressing the lien, as this can create legal complications later.

Do I need to take a smog test if my vehicle is brand new?

No. Vehicles that are three model years old or newer are exempt from smog testing. A brand-new vehicle does not need a smog inspection before registration. Bring proof of the vehicle's model year (the title or purchase agreement shows this) to the DMV.

How long does it take to get my California license plates after registration?

You receive a temporary registration card at the DMV office when ready. California plates are mailed to your address within two weeks. Your vehicle is legally registered and can be driven during this time using the temporary registration card as proof.

What if I buy an out-of-state car but have not moved to California yet?

You have 20 days from the date you establish California residency, not from the date you buy the car. If you buy a car out of state and move to California later, the 20-day clock starts when you move. Register the vehicle within that window to avoid late penalties.
