Every registered vehicle in Mississippi must be renewed once a year through the county tax collector — never through a single state DMV, because Mississippi doesn't have one. The renewal transaction combines a state privilege tax, a flat registration fee, and a county-set ad valorem tax based on the vehicle's value, all collected together when the tag is renewed.
Two things trip people up more than anything else: the renewal month is not your birthday, and whether you can renew online depends on which of Mississippi's 82 counties you live in.
2026 figures
Several popular "how to renew" pages claim Mississippi ties your tag renewal to your birth month. The Mississippi Code says otherwise: under §27-19-31, the registration year runs from the month the vehicle was acquired, and that same month becomes your permanent renewal, or “anniversary,” month every year after — regardless of whose birthday falls when. Multiple county tax collectors describe it the same way: your renewal month is the month you bought the vehicle, full stop.
Your renewal notice, mailed by your county roughly a month ahead of that anniversary month, is the most reliable way to confirm your own date if you're unsure.
Who has to renew, and when
Registration is annual. Mississippi's code also allows the Department of Revenue to issue a physical tag that's valid for up to five years, with a small renewal decal mailed for each of the intervening years rather than a whole new plate — but from the owner's side, the obligation is the same every year: pay the tax due and get the current-year decal before the anniversary month ends.
Your county tax collector mails a courtesy renewal notice, typically about a month before your anniversary month, listing your recalculated ad valorem tax and fees for the coming year. You're still responsible for renewing on time even if the notice is lost, delayed, or never arrives — the office cannot waive the late penalty for a missing notice.
How to renew: online, by mail, or in person
All three methods run through your county tax collector's office, and which are available to you depends on where you live.
| Method | Availability | Notes |
|---|---|---|
| Online | County-by-county | Some counties process it through the state's MV e-Services system; many others run their own independent payment site; some offer no online option |
| By mail | Most counties | Send your renewal notice or registration along with payment; check your county's preferred mailing address first |
| In person | Every county | At the county tax collector's office; you receive your registration and decal on the spot |
What you'll need
Any one of the following identifies your vehicle to the tax collector's office: your renewal notice, your tag (license plate) number, your title number, or your VIN. You'll also need a way to pay the tax and fees due (cash or check in person; a debit or credit card for most online systems).
Mississippi requires motor vehicle liability insurance, but the state verifies it electronically at renewal through the Department of Public Safety's insurance verification system rather than asking you to hand over a paper card. If the system can't confirm active coverage on your vehicle, expect your renewal to be held until you sort it out with your insurer or the tax collector.
Fees: ad valorem tax, privilege tax, and the Legislative Tag Credit
Three things make up a renewal bill:
- Ad valorem tax — assessed value is set at roughly 30% of the vehicle's original MSRP, reduced for depreciation over about ten years, with a $100 minimum for passenger vehicles. That assessed value is then multiplied by your county's own millage rate, which is why the same car costs a different amount to renew in different counties. This applies to vehicles of 10,000 lbs gross vehicle weight or less; heavier vehicles fall under a different ad valorem classification.
- State privilege tax and a flat registration fee, the same statewide regardless of county.
- The Legislative Tag Credit — a credit against the ad valorem tax that the Legislature created in 1994, recalculated each year by the Department of Revenue against the balance of a dedicated state fund. It's applied automatically when you renew on time.
Once your late penalty reaches its 25% maximum, you are no longer eligible for the Legislative Tag Credit on that renewal — on top of paying the maximum penalty, you lose the one discount that would have partly offset it. It's a bigger reason to renew inside the grace period than the headline penalty percentage alone suggests.
The grace period and late penalty tiers
Mississippi gives every renewal a 15-day grace period after expiration before any late penalty applies. After that, the penalty is charged against your ad valorem tax in escalating steps:
| How overdue | Penalty on ad valorem tax |
|---|---|
| 0–15 days past expiration | None — grace period (see caution below) |
| 16–45 days past expiration | 5% |
| 46–75 days past expiration | 10% |
| 76–105 days past expiration | 15% |
| 106–135 days past expiration | 20% |
| 136+ days past expiration | 25% (maximum) — Legislative Tag Credit forfeited |
Caution The 15-day grace period only affects when the late fee starts — it does not mean you can legally drive on an expired tag during those 15 days. At least one county tax collector's office explicitly notes that a vehicle can still be cited by law enforcement for an expired tag within the grace period.
Driving on an expired registration
An expired tag is a citable traffic offense in Mississippi at any point after expiration, independent of whether the DOR's administrative grace period and penalty have kicked in yet. Fines are set and collected at the county/municipal court level and vary by jurisdiction, so there's no single statewide dollar figure to quote. If you're cited, some courts will dismiss the ticket once the registration is brought current and the citation is signed off by the issuing officer — but that's a matter for the specific court, not something this site (or any private site) can promise.
How to check if your county offers online renewal
There is no single Mississippi-wide renewal website. The Department of Revenue's own online tag renewal page splits counties into two groups: a short list that renews directly through the state's MV e-Services platform (Franklin, Coahoma and Clay counties, as of this writing), and a much longer list of counties that have built and linked their own independent online renewal system — Madison, Rankin, Harrison, Hinds, DeSoto, Jackson and dozens of others among them. If your county isn't listed on either, the Department of Revenue's own page states it isn't offering online renewal, or hasn't told the state that it is.
The fastest way to check your own county: search the Department of Revenue's online tag renewal listing (linked in Sources below) for your county's name, or call your county tax collector's office directly and ask.
