What to Do AFTER You Sell Your Car in California (the 5-Day NRL Deadline)

You have 5 days from the sale date to file a Notice of Release of Liability with the California DMV. Miss that window and parking tickets, toll violations, and even accident claims from the new owner can still land on you, because the DMV still shows you as the legal owner until the buyer registers the car in their name.

I am Joe Yavetz, a licensed dealer in the San Fernando Valley. I have bought over 50,000 cars in California, and I have talked too many sellers off the ledge after they got a $185 parking ticket for a car they sold four months ago. The full step-by-step process for the whole sale lives in our main California car selling guide. This article is the part most guides skim over: what you actually do once the buyer drives off.

The 5-Day Countdown: What to Do and When

California's post-sale window is short and specific. Treat it like a countdown.

Day 0 (the sale itself). Before the buyer leaves, you walk away with three things: a signed bill of sale showing the date and price, a photo of the signed title (front and odometer section), and the buyer's full legal name and address as it appears on their driver's license. Without those, you have no proof the sale happened on the date you say it did.

Days 1 to 3 (recommended action window). Cancel or transfer your car insurance. Pull your personalized plates if you have them (REG 17). Save the title photo and bill of sale to cloud storage so you have it even if your phone dies. If you took cash over $10,000, note the date and amount in your records.

Day 5 (the hard deadline). File the Notice of Release of Liability at dmv.ca.gov/nrl. This is the one task you cannot skip. Calendar it the same day you sell the car. Set a phone reminder. Do it from the buyer's driveway if you have to.

Day 30 and beyond (the tail risks). Most issues from a sale show up in the first 30 days, but I have seen tickets and DMV notices arrive months later. Keep the bill of sale and your NRL confirmation forever. Scan them. Email them to yourself. This is a 30-second insurance policy that pays out if anything ever goes sideways.

When I buy a car as a licensed dealer, I file the NRL for the seller the same day from my phone, before I leave their driveway. That is part of the dealer service. If you are selling privately, this part is on you.

How Do I File the Notice of Release of Liability in California?

The NRL is California DMV form REG 138. You file it online at dmv.ca.gov/nrl. It is free and takes about two minutes.

You will need:

• License plate number
• Last 5 digits of the VIN
• Date of sale
• Buyer's full legal name and address
• Selling price (the DMV asks but does not share it)

Submit the form and the DMV emails you a confirmation. Save that email. Print it if you want a paper copy. That confirmation is what protects you if the new owner racks up tickets before they register the car.

If you do not have internet access, you can mail in a paper REG 138 to the address on the form, but you are still bound by the 5-day window. The date stamp on the envelope counts. Filing online is faster and gives you a same-day confirmation.

One detail people miss: the NRL is separate from the title transfer. Filing the NRL does not transfer the car into the buyer's name. That is the buyer's job at the DMV. The NRL just tells the DMV "I no longer own this car as of [date]." Two different forms, two different responsibilities.

What Happens If I Forget to File the NRL?

I will tell you what I have seen. Three real stories from sellers who called me afterward.

The parking ticket. A woman in Encino sold her 2017 Civic in November. The buyer was a guy who said he was buying it for his daughter. She did not file the NRL. In March, she opened her mailbox and there were three parking tickets from Santa Monica for a total of $385. The car had been parked in street-cleaning zones every Tuesday. The buyer's daughter was a student at SMC. The mom had to fight every ticket individually, prove the sale, and the city eventually rescinded them, but it took her four months and three phone calls per ticket.

The red light camera. A retired guy in Thousand Oaks sold his pickup to a buyer off Facebook Marketplace. Two weeks later he got a red light camera ticket in the mail with a photo of the truck running a light in Burbank. He had to drive to traffic court, bring the bill of sale, and argue his case with a clerk who initially refused to look at it because there was no NRL on file. It got resolved, but only because he had the dated bill of sale.

The accident. This is the one that keeps me up at night. A guy in Woodland Hills sold a 2014 Camry to a buyer who did not have insurance. Two months later, the buyer rear-ended someone on the 101. The injured party's attorney pulled the registered owner's name (still the seller's, because no NRL was filed) and sent a demand letter. The seller spent $1,200 on a lawyer to clear his name. He had the bill of sale. He did not have an NRL filing. The lawyer eventually got it dismissed but it was a five-month headache.

In every one of those cases, a 2-minute online form would have stopped the problem at the source.

Should I Take My License Plates Off the Car in California?

Depends on what kind of plates you have.

Standard plates stay with the vehicle in California. You do not remove them. The buyer drives off with the plates and your registration sticker, and they register the car in their name at the DMV within 10 days.

Personalized plates (vanity plates) can be retained. You submit a REG 17 (Special Interest License Plate Application) to keep them. The DMV either holds them for you to put on your next car, or you can surrender them. If you want to keep the plate, decide before the sale and physically remove it from the car the day of the transaction. Once the buyer drives off with the plate attached, the DMV treats it as part of the sale.

Special interest plates (environmental, veteran, collegiate) follow the same retention process as personalized plates. REG 17, decide before the sale.

I have had sellers come back to me a week later asking "can I still get my vanity plate back?" The honest answer is no. Once it leaves on the car, it leaves with the car.

When Should I Cancel My Car Insurance?

The day of the sale, after the buyer takes possession. Not before.

Here is the order:

1. Buyer hands you payment, you hand them the keys, both of you sign the bill of sale.
2. Buyer drives off with the car.
3. You call your insurer the same day.

If you cancel before the buyer drives off, and something happens during the test drive or the transfer of keys, you are exposed. If you cancel a day or two later, you have been paying premiums on a car you no longer own. Same-day, after the keys change hands, is the right window.

If you are buying another car, ask your insurer about a vehicle transfer instead of a cancellation. This keeps your continuous coverage history intact, which matters for your rate at renewal. Most insurers prorate the refund either way.

One more thing: do not let the buyer drive away on your insurance policy. Some sellers think they are being nice by letting the buyer "test drive home" before switching coverage. If that buyer hits someone on the way, your policy is on the hook.

Do I Owe Taxes on a Private Car Sale in California?

Probably not, but it depends.

Sales tax (the buyer's problem). California use tax is the buyer's responsibility. They pay it when they register the car. Base rate is 7.25%, plus local taxes up to about 10.75% depending on the county. You as the seller owe nothing for use tax.

Income tax. If you sold the car for less than you paid for it, no income tax. That is almost always the case with personal vehicles. If you somehow sold it for more than you paid (rare, but happens with classics or rare models), the difference is a capital gain that gets reported on your federal taxes.

The $10,000 cash rule. If a business buys your car for more than $10,000 in cash, the business is required to file IRS Form 8300. That is the buyer's filing, not yours. Private buyers (regular people, not dealers) do not file 8300 even on large cash deals. But banks may report large cash deposits to the IRS, which is a separate issue. If you take a $15,000 cash deal, deposit it in normal amounts over a few days and keep your bill of sale handy.

The other paperwork-needed-to-sell-a-car-in-california details (title, smog, bill of sale, odometer) are covered in our pillar guide and the as-is selling guide. This article is post-sale only.

What If the Buyer Never Registers the Car in Their Name?

You filed the NRL. Your hands are clean from the date you filed forward.

The car sits in the DMV system as a transferred vehicle waiting for the new owner to complete registration on their side. That is the buyer's problem, not yours. Tickets from that point forward route to the buyer, not you, because your NRL filing established the transfer date.

If the buyer fails to register and the car ends up impounded or abandoned, the DMV may eventually contact you as the prior owner for information. Respond with your NRL confirmation and the bill of sale. That ends your involvement.

This is also why I tell people: file the NRL even if you trust the buyer. Even if it is your cousin. Even if you sold the car to a friend. The NRL is not about distrust. It is about closing the legal loop on your end.

What If I Get a Ticket for a Car I Already Sold?

Contest it. Every time.

The process:

1. Open the ticket. Note the date of the violation.
2. Compare to the date on your signed bill of sale. Violation date should be after sale date.
3. Pull up your NRL confirmation email.
4. Contact the agency that issued the ticket (city parking, traffic court, toll authority) and explain that you sold the vehicle before the violation. Attach the NRL confirmation and the bill of sale.
5. The agency redirects the ticket to the new owner using the NRL filing.

If you filed the NRL on time, this usually resolves in one phone call or one form submission. If you missed the 5-day window, it gets harder. You will need to prove the sale date through the bill of sale and possibly through bank records or witness statements. Doable, but slow. Sometimes 30 to 90 days. This is why the 5-day filing matters.

What If the Sale Went Sideways and the Buyer Returned the Car?

Rare, but it happens. If the buyer returns the car within a few days (maybe they could not get financing, maybe their spouse said no), and you both agree to unwind the sale:

• Refund the money. Get a signed acknowledgment from the buyer that the deal is canceled.
• If you already filed the NRL, file a new NRL canceling it or contact the DMV at 1-800-777-0133 to explain the situation. Bring the unwound bill of sale.
• Your insurance status: if you canceled, you have to reinstate. There may be a gap in your continuous coverage. Tell your insurer the truth.

Most private sales close cleanly and stay closed. But know the unwind process exists.

What If I Want to Skip All of This?

Sell to a licensed dealer.

When I buy a car as part of CurbSold, I handle the NRL filing for you the same day from my phone, right there in your driveway. I file the title transfer with the DMV under my dealer license, so the car comes off your name fast. I take the plates if they are personalized and you want to keep them, or leave them on if they are standard. The bill of sale comes from my dealer system and is dated, signed, and emailed to you before I drive away.

That is the quieter value of selling to a licensed dealer. Not just the price (I match or beat any CarMax offer. Guaranteed.) and not just the convenience (I come to you in the San Fernando Valley, Ventura County, and Conejo Valley). The paperwork side of the sale closes cleanly the same day, with no 5-day countdown on you.

If you want me to look at your car, the number is (818) 325-7535. Call or text. I will give you a rough idea on the phone with the VIN and a couple photos, and we can set up a time for me to come out for the firm offer. The full step-by-step for the rest of the California selling process is in our main guide. Sibling articles you may want: selling a car as-is in California and transferring a car title to a family member.

Frequently Asked Questions

What happens if I don't file a release of liability in California?

Until the buyer registers the car in their name, the DMV still lists you as the legal owner. Parking tickets, toll violations, red light camera fines, and any accidents involving the vehicle can come back to you. Filing the NRL at dmv.ca.gov/nrl within 5 days transfers liability to the new owner from the date of sale.

How long do I have to file the release of liability in California?

Five days from the date of sale. The form is REG 138, filed online at dmv.ca.gov/nrl. It is free and takes about two minutes.

Do I keep my license plates when I sell my car in California?

Standard plates stay with the vehicle. Personalized or special interest plates can be retained if you submit a REG 17 with the DMV. Decide before the sale because once the title transfers with the plates, you cannot pull them back.

When should I cancel my car insurance after selling my car?

Cancel or transfer coverage the same day the sale closes, AFTER you have the signed bill of sale and the buyer has taken possession. Do not cancel before the buyer drives off. Most insurers prorate the refund.

Do I have to report the sale to the IRS?

Most personal car sales are not reportable income because you almost always sell for less than you paid. If you sold for more than your purchase price, the difference is a capital gain. Cash transactions over $10,000 trigger a Form 8300 filing by the buyer if the buyer is a business. Private buyers do not file 8300.

What do I do if I get a ticket for a car I already sold?

Contest it with the agency that issued the ticket. Provide a copy of your filed Notice of Release of Liability and the signed bill of sale showing the date of sale was before the date of the violation. If you filed the NRL on time, the agency redirects the ticket to the new owner.

What if the buyer never registers the car in their name?

Your NRL filing still protects you from tickets and accident liability from the date of sale forward. The car stays in the DMV system as a transferred vehicle waiting for the new owner to complete registration. Your name comes off the active registration list once you file the NRL, regardless of whether the buyer follows through on their end.
