If you’re staring at your registration notice and wondering about smog timing, this guide explains what you can pay now, what still depends on an inspection, and what happens if you don’t get the test done. You’ll also learn where DMV-related steps fit in, including options like a temporary operating permit.
The core rule in plain words
In California, smog inspections are often required for renewal of a vehicle registration. The important detail is this:
You may be able to pay the renewal fee first
But your registration paperwork that includes the sticker is tied to passing smog.
Think of it like a two-step process:
- Pay the registration fees.
- Complete the smog check and provide proof once the inspection is done.
Can you pay your registration before smog
Short answer
Yes, you can usually pay first.
What changes after you pay
- Your payment can be accepted so you don’t rack up more penalties.
- But the new registration sticker and card are not fully released until the DMV receives proof that you passed smog.

What happens if you renew but don’t complete smog
Imagine you paid on time, but the smog inspection never happened. In that situation, you shouldn’t assume you’re fully registered.
A key outcome is that the registration can be placed into a “not fully valid” situation while smog is pending. That means you could face issues even though you paid.
Quick comparison
| Situation | Payment status | Smog status | Sticker/card | Practical risk |
|---|---|---|---|---|
| Pay first, then pass smog | Paid | Passed | Issued after proof | Lower risk |
| Pay first, smog not done yet | Paid | Not completed | Not fully released | Higher risk if driven |
| Pay first, smog failed | Paid | Failed | Not released as “passed” | You must follow next steps |
Which vehicles may be exempt from smog checks
Some vehicle types do not need a smog check for renewal. Common exemptions include:
- Gasoline-powered vehicles that are 1975 model year or older (including motorcycles and trailers)
- Diesel-powered vehicles that are 1997 model year or older, or with gross vehicle weight over 14,000 pounds
- Vehicles powered by natural gas and weighing more than 14,000 pounds
- Electric vehicles
- Gasoline-powered vehicles that are less than eight model-years old
Also, there is a specific newer-vehicle rule:
- Starting January 1, 2019, if your vehicle is less than 4 model years old, you can pay a smog abatement fee instead of getting a smog inspection for the first 8 years it is registered.
Are there exceptions for new vehicles
Yes. If your new car is under certain model-year thresholds, California may allow you to avoid the standard smog inspection route by using a fee program instead.
A clear summary:
| Vehicle age condition | Smog requirement approach |
|---|---|
| Less than 4 model years old | Pay a smog abatement fee instead of an inspection for first 8 years |
| Gasoline-powered and less than 8 model-years old | Smog inspection not needed for renewal (per the exemption list) |
If your car fails smog, what to do next
Failing smog doesn’t usually end the process—it changes it.
Step you should take
- Contact the BAR Referee Program to get help on next steps.
- They also help you understand what options apply after a smog failure.

What if your registration is due and your car won’t pass yet
If timing is tight, California offers a way to stay legal while you fix issues.
Temporary Operating Permit (TOP)
A temporary operating permit can be related to smog requirements when you need extra time. The permit concept is meant for short-term operation while you handle smog problems.
This is especially relevant if your car won’t pass the inspection by the time your registration renewal deadline hits.
Counties where smog inspection is required for renewal
California requires smog inspections for renewal in specific counties. The counties listed include:
Alameda, Butte, Colusa, Contra Costa, Fresno, Glenn, Kern, Kings, Los Angeles, Madera, Marin, Merced, Monterey, Napa, Nevada, Orange, Sacramento, San Benito, San Francisco, San Joaquin, San Luis Obispo, San Mateo, Santa Barbara, Santa Clara, Santa Cruz, Shasta, Solano, Stanislaus, Sutter, Tehama, Tulare, Ventura, Yolo, Yuba.
How to find a DMV-authorized smog check station
To find where to go for a smog check:
- Use the DMV’s guidance to locate a DMV-authorized smog check station near you
- You can also visit the Bureau of Automotive Repair (BAR) for help
If your DMV renewal notice tells you to go to a specific program station, follow that instruction.
What is a STAR station
A STAR station is part of California’s smog system.
- The California STAR program began January 1, 2013
- The STAR program sets smog check standards
- It replaced older programs like Gold Shield and Test Only
If your renewal notice indicates a STAR location is needed, it’s important to follow that requirement.
Special cases readers often ask about
Gifted cars and smog
In many cases, a car gifted within the family does not automatically trigger a smog requirement. But there’s an important exception:
- No smog is required for a family gift in general
- However, if the car was bought “for you” but not titled in their name first, then a smog inspection is required
Selling a vehicle and smog
When selling:
- You generally need to give the new owner a valid smog certification
- If the car is less than four years old, a smog inspection is not required; instead, the new owner pays a smog transfer fee
Military exemption
There is no military exemption from the smog inspection requirement. Active duty military and military veterans still need to get the smog inspection when required.
Payments, fees, and smog status
Here’s the practical answer to the worry behind the search phrase.
Can you pay your registration fees without a passed smog test
Yes, you can pay. But:
- Your sticker/card is not fully issued/shipped until DMV receives proof of a passing smog check.
What about repair cost help
If your vehicle fails smog, you may qualify for assistance like a repair cost waiver through the referee process path (availability depends on your situation).
Failures and registration stickers
If your smog test isn’t passed, your registration sticker won’t be released as if you’re compliant. Even if payment was made, the final step depends on proof that the inspection requirements were met.

Summary you can use immediately
- Yes, you can often pay registration fees before smog.
- Your sticker/card depends on the DMV receiving proof of a passed smog inspection.
- If you renew and don’t complete smog, your registration can be treated as not fully valid while smog is pending.
- If timing is tight, a temporary operating permit (TOP) may help you get through the gap.
- Certain vehicles are exempt, and newer cars may use the smog abatement fee instead of an inspection.
