The smog abatement fee in California is an annual charge the DMV adds to your vehicle registration when your car is new enough to be exempt from the biennial smog inspection. Instead of taking the vehicle to a smog check station, you pay the fee and your emissions requirement is considered satisfied for that registration period.
How Much You Pay
California Health and Safety Code Section 44060 sets two tiers based on how old the vehicle is:
- Six or fewer model years old: $12 per year.
- Seven or eight model years old: $25 per year.
The higher charge in years seven and eight came in with AB 1274, which extended the smog check exemption from six model years to eight and attached a steeper fee to those final two years. Revenue goes into the Vehicle Inspection and Repair Fund, which supports the state’s emissions testing program.
You don’t need to calculate the fee yourself. It appears as a line item on your registration renewal notice alongside your other charges. The DMV’s published fee schedule sometimes lists the smog abatement line at $20, which reflects additional surcharges layered on top of the $12 statutory base; the number on your actual notice is what you owe.
Which Vehicles the Fee Applies To
Since January 1, 2019, California has exempted motor vehicles eight or fewer model years old from the smog inspection otherwise required at registration renewal. Those vehicles pay the abatement fee in place of the inspection. The count runs on model year, not purchase date. A 2026 model-year vehicle, for example, would pay the fee through its 2034 renewal and then move into the standard smog check cycle.
The exemption, and therefore the fee, covers gasoline, hybrid, and alternative-fuel vehicles. A hybrid eight model years old or newer is treated the same as a gasoline car: pay the fee, skip the inspection.
Electric Vehicles
Battery electric vehicles produce no tailpipe emissions and are exempt from smog inspections at any age. Some EV owners have still seen a smog abatement charge appear on their renewal, depending on how the DMV’s system classified the vehicle. If that happens, contact the DMV to request a review.
Diesel Vehicles
Diesel-powered vehicles are not part of the eight-year age exemption and do not pay the smog abatement fee. Diesels from model year 1997 and older, and any diesel with a gross vehicle weight above 14,000 pounds, are exempt from smog inspection entirely. Newer, lighter diesels follow the standard biennial smog check cycle regardless of age.
When You Still Need an Actual Smog Check
Paying the fee covers routine renewal, but not every situation. Two common ones pull you back into an inspection even when the vehicle is within the eight-year window.
Bringing a Vehicle In From Another State
A vehicle registered for the first time in California needs a smog inspection as part of that initial registration, even if it’s brand new. The age-based exemption does not apply to out-of-state vehicles coming in. Once the vehicle clears that first inspection and is registered in California, it qualifies for the abatement fee for its remaining eligible model years.
Selling or Transferring the Vehicle
A change of ownership follows its own rules. Vehicles four model years old or newer do not need a smog inspection to transfer; the new owner pays a smog transfer fee to the DMV instead. Vehicles five or more model years old require the seller to provide a valid smog certificate before the title can transfer, even though the car has never needed an inspection for the seller’s own renewals. The smog transfer fee charged on newer-vehicle sales is a separate, smaller charge, not the annual abatement fee.
How You Pay It
The fee is bundled into your registration renewal. You pay it the same way you pay the rest of your renewal charges: online, by mail using the envelope sent with your renewal notice, at a self-service kiosk, or at a DMV office. Once the payment processes, the DMV’s system records that your smog obligation is met for the period. There is no certificate to produce and no inspection appointment to make.
When the Fee Goes Away
Once your vehicle crosses the eight-model-year line, the abatement fee drops off your renewal and the vehicle enters the standard biennial smog inspection cycle. From then on, you need to visit a licensed smog check station, pass the emissions test, and have the certificate transmitted to the DMV before registration can be completed. A typical inspection runs roughly $50 to $80, depending on location and whether a basic or enhanced test is required. Knowing when that transition is coming makes it easier to schedule the first inspection without rushing against a renewal deadline.
