Step-by-Step: How to Renew Your Missouri License Plates
Step 1: Check If You Need Inspections
This is where most people get confused. Missouri has two types of vehicle inspections, and whether you need them depends on your car and where you live.
Safety Inspection
You need a safety inspection if your vehicle is:
- 10 years old or older, OR
- Has 150,000 miles or more
If your car is newer than 10 years AND has less than 150,000 miles, you're exempt from safety inspections.
Safety inspections are required every 2 years. Your car's model year determines which years you need to test:
- Even-year vehicles (2020, 2022, 2024): Get inspected in even years (2024, 2026, etc.)
- Odd-year vehicles (2021, 2023, 2025): Get inspected in odd years (2025, 2027, etc.)
Cost: $12 maximum (state-regulated)
Emissions Inspection
This is the big one that confuses people. Emissions inspections are only required in 4 Missouri counties:
- St. Louis County
- St. Louis City
- St. Charles County
- Jefferson County
If you live anywhere else in Missouri, you don't need an emissions inspection. If you do live in one of these counties, emissions tests follow the same every-2-years, even/odd schedule as safety inspections.
Electric vehicles are exempt from emissions inspections (but hybrids still need them).
Cost: $24 maximum (state-regulated)
Important: Inspections are only valid for 60 days when renewing your plates. Don't get them done too early!

Step 2: Get Your Property Tax Receipt
Missouri requires proof that you've paid personal property taxes on your vehicle before you can renew your plates. You need to get this from your county's Collector of Revenue office.
How many years do you need?
- 1-year renewal: Need the previous year's receipt (for 2025 renewals, you need your 2024 receipt)
- 2-year renewal: Need the previous TWO years' receipts (for 2025 renewals, you need 2023 AND 2024)
What if I don't owe property taxes?
Some vehicles don't have personal property taxes due. In this case, you need a "Statement of Non-Assessment" from your county collector instead of a receipt.
Most counties let you get receipts online, by phone, or in person. Search for "[Your County] Missouri Collector of Revenue" to find your local office.
Step 3: Gather Your Other Documents
Besides inspections and tax receipts, you'll need:
- Your renewal notice (the card the DMV mails you) - but if you lost it, don't worry! You can still renew with just your license plate number and VIN.
- Proof of insurance - Your current insurance card showing you have Missouri minimum coverage
Step 4: Choose How to Renew
Missouri gives you several options for renewing your license plates:
Online Renewal (Easiest)
Most Missouri counties allow online renewal at dor.mo.gov. You'll enter your plate number, pay with a credit card, and get your new sticker mailed to you. This is the fastest option if you don't need to update your address or other info.
Note: Mercer County occasionally doesn't allow online renewal - call your local license office to check.
In Person
Visit your local license office. Bring all your documents and payment. You'll walk out with your new sticker the same day.
By Mail
Mail your documents and payment to your local license office. This is slower but works if you can't get there in person.
By Phone
Some counties allow phone renewal. Call your local license office to see if this is available.
Missouri License Plate Renewal Fees
Registration renewal fees in Missouri vary based on:
- Your vehicle type (passenger car, truck, motorcycle, etc.)
- Vehicle weight and horsepower
- Your county (some add local fees)
For exact fees, check the Missouri DOR fee schedule.
Typical costs you'll pay:
- Registration renewal fee: $25-$75 (varies by vehicle)
- Processing fee: Usually $3.50-$6
- Safety inspection (if needed): Up to $12
- Emissions inspection (if needed): Up to $24
Common Missouri Plate Renewal Mistakes to Avoid
1. Getting inspections too early
Inspections are only good for 60 days. If you get them done 3 months before renewal, they'll expire before you can use them.
2. Forgetting about property tax receipts
This trips up a lot of people, especially if you're renewing online. You can't complete your renewal without proof of paid property taxes.
3. Assuming you don't need an emissions test
If you moved from another Missouri county into St. Louis County, St. Louis City, St. Charles, or Jefferson County, you now need emissions tests even if you didn't before.
4. Thinking hybrids are exempt from emissions
Only fully electric vehicles skip emissions tests. Hybrids still need them in the 4 applicable counties.
5. Not knowing your inspection schedule
The even/odd year system confuses people. A 2020 vehicle gets inspected in 2024, 2026, 2028, etc. - not every year.
Where to Get Vehicle Inspections in Missouri
Safety Inspections:
Any Missouri-authorized safety inspection station can do these. Most auto repair shops, dealerships, and quick lube places offer safety inspections. Find a station near you at the Missouri State Highway Patrol station locator.
Emissions Inspections:
These require special equipment. Look for GVIP (Gateway Vehicle Inspection Program) certified stations. Find one at the Missouri GVIP station locator.
Frequently Asked Questions
Can I renew my Missouri plates if I'm out of state?
Yes! You can renew online or by mail even if you're not physically in Missouri. You'll still need to get any required inspections done at a Missouri-certified station, though.
What happens if I don't renew on time?
You can get pulled over and ticketed for driving with expired plates. Missouri gives you a 30-day grace period after your expiration date, but it's best to renew on time to avoid any issues.
Do I need a new inspection every year?
No. Inspections in Missouri are biennial (every 2 years), not annual. Check your vehicle's model year to know which years you need to get inspected.
Can I transfer my old plates to a new car?
In some cases, yes. Contact your local license office for details on plate transfers. This is different from standard renewal.
What if I just moved to Missouri?
You have 30 days to register your vehicle in Missouri after establishing residency. This is different from renewal - you'll need to apply for new Missouri plates and go through the initial registration process.
