How to Register an Out-of-State Vehicle in California (2026)
If you move to California with a car from another state, you have 20 days from the day you become a resident to register it here. This has to be done in person at a DMV office and you can't do it online. You'll need a smog check, California insurance, and you'll likely owe some use tax based on what the car is worth.
So you just moved to California and brought your car with you and Register an Out-of-State Vehicle in California. The Good news is it's a straightforward process. Whereas the bad news is that it's a little more paperwork than registering a car you bought in California, and the clock starts ticking the moment you move.
The 20-Day Deadline
You have 20 days from the day you become a California resident to get your car registered. "Becoming a resident" isn't just about moving your stuff here .It also includes things like getting a job in California, registering to vote here, or enrolling your kids in a California school. Basically, anything that shows you plan to live here counts.
Once that clock starts, your old state's registration stops being valid in California. Don't wait until day 18 to start — get moving on it as soon as you land.
If you bought this car recently in another state and are now moving here, the 20-day residency clock applies AND not the 10-day private-sale rule. That rule only applies to cars bought from a California seller.
Documents Required to Register an Out-of-State Vehicle in California
The following documents are a must have to register your Out-of-State Vehicle
- Original out-of-state title (not a photocopy),
- Your out-of-state registration card
- Proof of California insurance
- A completed REG 343
- Payment for registration fees and use tax.
Step-by-Step: Registering Your Out-of-State Car
- Get a smog check first. Even if your car is brand new, or the kind of car that's normally exempt from smog checks once it's registered in California, that exemption doesn't apply here. Almost every out-of-state vehicle needs to pass a California smog inspection before it can be registered, regardless of age. Get this done before you go to the DMV — it saves you a second trip.
- Make sure your insurance meets California's rules. Your policy from your old state might not cover what California requires. Call your insurer and confirm your coverage meets California's minimums before you show up at the DMV.
- Gather your paperwork. The documents mentioned in the documents required section.
- Go to a DMV office in person. A DMV employee needs to physically check your car's VIN against your paperwork. There's no way around this step .It can't be done online or by mail.
- Pay your fees, including use tax. California charges use tax on vehicles brought in from other states, calculated on the purchase price or current fair market value, whichever is higher, at 7.25% state base plus your local district rate.
- Hand over your old plates. Once you're registered in California, you'll get new California plates. Your old state's plates generally need to go back to that state, or get surrendered at the DMV.You need to check your home state's rules too.
Use Tax - What You'll Actually Owe
This is the part that catches people off guard the most. California charges use tax on out-of-state vehicles, based on either the purchase price or the car's current fair market value, whichever is higher.
| Item | Detail |
|---|---|
| State use tax rate | 7.25% |
| Local / district add-on | 0.10%–2.0%, depending on where you live |
| Credit for tax paid elsewhere | Yes, up to California's rate — you pay the difference if your old state's rate was lower |
| Based on | Purchase price or fair market value, whichever is higher |
If you're bringing in a car worth $20,000–$30,000, budget for a few thousand dollars in use tax alone, on top of standard registration fees. For the full fee breakdown — base registration, VLF, CHP fee, and more — see our main California registration guide.
Why the Smog Check Trips People Up
If you've owned a California-registered car before, you might know that cars less than 8 model years old are usually exempt from smog checks. That exemption does not carry over to out-of-state vehicles.
It doesn't matter if your car is 2 years old and passed an emissions test in your old state last month. Cooming into California for the first time means you almost always need a fresh California smog check. Your renewal notice will tell you whether you need one going forward after that.
Mistakes People Keep Making
- Assuming your car doesn't need a smog check because it's newer. The out-of-state exemption doesn't work the same way as California's age-based exemption. Get it checked.
- Not confirming your insurance meets California minimums beforehand. Showing up with an out-of-state policy that doesn't qualify means a wasted trip.
- Waiting too long to start the process. 20 days goes by fast, especially during a move. Start as soon as you land.
- Forgetting you'll owe use tax. This is the fee people are least prepared for. Budget for it ahead of time so it's not a surprise at the counter.
