When Does My Mississippi Tag Expire?
Mississippi vehicle registrations, called “tags” locally, expire on the owner’s birthday each year. Your county tax collector mails a renewal notice approximately 30 to 60 days before your birthday expiration date. If you do not receive a renewal notice, you are still responsible for renewing your tag on time.
Mississippi operates a decentralized registration system through its 82 counties. Each county’s tax collector administers vehicle registrations independently. This means your registration is handled by your county of residence, not a state-level DMV, and your specific renewal options, including whether online renewal is available, depend on your county.
Your vehicle must be registered in your county of residence, specifically, the county where the vehicle is domiciled or parked overnight. If you move to a different county in Mississippi, you must re-register in your new county of residence.
Does Mississippi Require an Emissions Test for Renewal?
No. Mississippi eliminated its vehicle emissions testing program and does not require any emissions test or safety inspection for registration renewal statewide. This applies to all vehicle types in all 82 counties. There is no smog check, no testing station to visit, and no inspection certificate to submit.
Mississippi has no statewide emissions testing or safety inspection requirement for registration renewal. Pay your taxes and fees to your county tax collector; that is the entire renewal process.
How Do I Renew My Mississippi Tag?
Mississippi offers up to three renewal methods depending on your county. Not all 82 counties participate in the online renewal portal: check dor.ms.gov to confirm whether your county offers online renewal before attempting it.
Online at MV e-Services (Participating Counties Only)
Visit dor.ms.gov and navigate to Motor Vehicle e-Services. Select your county and follow the online renewal steps. You will need your plate number or renewal notice information and a valid credit or debit card. Your new decal is mailed to your address on file. Check the MDOR website first, not all 82 counties participate in online renewal.
In Person at County Tax Collector’s Office
Visit your county tax collector’s office in person. Bring your renewal notice or current registration, proof of liability insurance, a valid Mississippi ID, and payment. Your new tag or decal is typically issued the same day. This is the most universally available option for all 82 counties.
By Mail
Return your completed renewal form with a check or money order payable to your county tax collector. Mail to the address on your renewal notice. Allow at least 2 to 3 weeks before your birthday expiration deadline. Confirm that your county accepts mail-in renewals before sending.
How Much Does a Mississippi Tag Renewal Cost?
Mississippi’s renewal cost has two main components: a base registration fee set by state law, and an ad valorem tax that varies significantly by county based on each county’s mill rate and your vehicle’s assessed value. Your total renewal bill is the sum of these two components.
| FEE COMPONENT | AMOUNT |
|---|---|
| Base registration fee (standard passenger vehicle) | $12.75 |
| Ad valorem tax | Varies by county mill rate and vehicle value, see section below |
| County privilege tax (where applicable) | Varies by county |
| Late penalty (if applicable) | 5% after 15-day grace period, increasing 5% per 30 days, max 25% |
Your county tax collector’s office can provide an exact estimate of your renewal cost. The MDOR website at dor.ms.gov also provides a tag fee calculator. Fees vary significantly between Mississippi’s 82 counties.
How the Mississippi Ad Valorem Tax Works
Mississippi charges an ad valorem (property) tax on registered vehicles each year at renewal. Unlike states with a flat fee, this tax is calculated based on the vehicle’s value and your county’s mill rate, both of which change over time. This means your renewal cost decreases as your vehicle ages and depreciates, and varies based on which county you live in.
The formula works as follows: Mississippi assesses vehicles at 30% of retail value for vehicles under 10 years old. A 5% legislative tag credit then reduces the assessed value before the county mill rate is applied. Vehicles 10 years and older receive a significantly reduced assessed value, resulting in lower annual ad valorem taxes.
| STEP | CALCULATION |
|---|---|
| 1. Assessed value | Vehicle retail value × 30% |
| 2. Legislative tag credit | Assessed value × 5% credit applied |
| 3. Net assessed value | Assessed value minus the credit |
| 4. Ad valorem tax | Net assessed value × (county mill rate ÷ 1,000) |
County mill rates across Mississippi’s 82 counties range from approximately 46 mills to over 170 mills. A vehicle with a $30,000 retail value registered in a high-mill-rate county can pay several hundred dollars more in ad valorem tax annually than the same vehicle in a low-mill-rate county. Your renewal notice shows the exact ad valorem tax due for your vehicle and county.
Grace Period and Late Penalties
Mississippi provides a 15-day grace period after your birthday expiration date before late penalties begin. On the 16th day of the month following expiration, a late penalty of 5% of the ad valorem tax due is applied. For every additional 30 days the tag remains overdue, another 5% penalty is added, up to a maximum of 25%.
| DAYS PAST EXPIRATION | LATE PENALTY |
|---|---|
| Days 1–15 | Grace period with no penalty |
| Day 16 through Day 45 | 5% of ad valorem tax due |
| Day 46 through Day 75 | 10% of ad valorem tax due |
| Day 76 through Day 105 | 15% of ad valorem tax due |
| Day 106 and beyond | Up to 25% maximum, then held constant |
What Can Block My Mississippi Renewal?
Lapsed liability insurance
Mississippi requires minimum liability coverage. Proof of current insurance is required at renewal.
Outstanding fines or court holds
Unpaid traffic fines reported to the county tax collector can block renewal.
Title or ownership discrepancy
Unreleased liens or title issues require in-person resolution at your county tax collector before renewal proceeds.
Wrong county
Mississippi registration is county-specific. If you have moved to a new county, you must register in your new county of residence.
