Most Utah County drivers renew their registration once a year, and many need an emissions test first. In 2026, gas vehicles from model years 1996 through 2020 need a test every year, while newer cars test every other year: 2022 and 2024 models test this year, and 2021, 2023, 2025 and 2026 models don't. You can renew up to 60 days before your registration expires, online in a few minutes once the test is on file.
Rules below are from the Utah Division of Motor Vehicles' inspection and renewal pages, Utah County's Bureau of Air Quality and Utah Code, read Nov. 9, 2026. Utah County is one of the Utah counties with an emissions program; our car ownership guide covers the bigger picture for newcomers.
Who needs an emissions test in 2026
The Utah DMV's 2026 table for Utah County:
| Model year | Test in 2026? |
|---|---|
| 2026, 2025 | No (new) |
| 2024 | Yes |
| 2023 | No |
| 2022 | Yes |
| 2021 | No |
| 2020 through 1996 | Yes, every year |
| 1995 and older | No |
The pattern: vehicles less than six years old test every two years, even model years in even years and odd model years in odd years, and new gas vehicles skip their first two years. Utah County's air quality office says gas vehicles seven model years and older test every year.
Diesels
- Model years 1998 to 2021: test required in Utah County.
- Exempt: 1997 and older, 2022 and newer, and diesels over 14,001 pounds GVWR. Utah County adds that new light-duty diesels are exempt for their first five years.
Exempt from emissions altogether
- Electric vehicles
- Motorcycles, motor-driven cycles and off-highway vehicles
- Engines of 650cc or less and two-stroke engines
- Farm implements and construction vehicles not licensed for the highway
- New vehicles with a manufacturer's statement of origin
Getting the test
- Timing: a test can be done no more than two months before your renewal.
- Cost: no set fee. Certified stations set their own price but have to post it, Utah County's Bureau of Air Quality says. Call around.
- Failed? The station gives you a vehicle inspection report listing the failures. Questions go to the Utah County Health Department's Bureau of Air Quality, 801-851-7600.
- Buying from a dealer: the test must have been done within 11 months before the sale.
Five ways to renew
| Option | How it works |
|---|---|
| Online | Renewal Express at secure.utah.gov/rex, with your VIN and the PIN from your renewal notice |
| On the SPOT station | Some inspection stations do the test and the renewal together and hand you the decal |
| Automatic renewal | Enroll through the Motor Vehicle Portal (MVP) or Form TC-505; the DMV checks inspections and charges your bank account on the renewal date and mails the decal |
| Send the renewal form, inspection certificate and fees to Motor Vehicle Division, P.O. Box 30412, Salt Lake City, UT 84130, payable to the Utah State Tax Commission | |
| In person | The Provo DMV, 150 E. Center St., Suite 1400, or any DMV office in the state |
You can renew 60 days before expiration, and your new registration usually keeps the original expiration month. Registrations expired more than six months have to be renewed in person. Utah also offers two-year registration for some vehicles.
Utah County has only one Motor Vehicle Division office, in Provo; it takes appointments and says walk-in availability after 4 p.m. may be limited. See our Provo DMV guide for parking and the difference between the DMV and the Driver License Division.
What registration costs
There's no single price, because the total depends on the vehicle's type, age and weight. The main pieces:
- The base registration fee. Utah Code sets it at $44 a year for most cars and light trucks up to 14,000 pounds and $46 for motorcycles, and requires an additional $7 on top, or $51 for a car. A version of the law taking effect Jan. 1, 2027, adds another 50 cents.
- The age-based uniform fee, charged in place of property tax on most vehicles and set by the vehicle's age.
- Hybrid and electric fees. By statute, hybrids pay $21.75 extra and plug-in hybrids $56.50; electric vehicles pay a fee tied to the state's road usage charge. These amounts adjust each January.
- The emissions test, paid to the station.
The DMV's fee estimator on dmv.utah.gov calculates the exact total for your vehicle, and your renewal notice lists it.
Safety inspections are mostly gone
Utah no longer requires a safety inspection to register a personal vehicle. They're still required for commercial vehicles (annually), rebuilt salvage vehicles, first-time street-legal ATVs and some motor homes.
New to Utah?
A car coming from another state needs a VIN inspection the first time it's titled in Utah, which an inspection certificate with the correct VIN can satisfy, plus Utah insurance and an emissions test if it applies. Our car ownership guide walks through it, and Utah driver license renewal covers the license side.
