How to renew a Mississippi car tag: online, by mail, or in person

The homepage covers renewal at a glance. This page goes one level deeper on the part people actually get stuck on: what each of the three renewal channels — online, by mail, and in person — concretely requires, and which online system you'll actually land on depending on your county.

All three channels still run through your county tax collector's office, never a state DMV. What differs is only the mechanics of paying and receiving your decal.

Mississippi's Department of Revenue maintains a current, county-by-county list of who offers online renewal and where it points. As of this review, that list showed 46 of Mississippi's 82 counties offering some form of online renewal — three through the state's own system, forty-three through a system the county set up itself. The remaining counties were not listed, meaning the Department's page had no online option on file for them. This list changes as counties add or drop vendors, so treat the count as a snapshot and check the Department's own page (linked above and in Sources) for your county specifically.

The county-run portals aren't one product. Madison County and Harrison County, for example, both route their online renewal through the same third-party payment platform (ibcpayments.com), while Jackson County uses a different vendor entirely (co-jackson-ms-taxpayments.us). There's no single interface to learn — each county picks and pays for its own, and some counties have switched vendors before. If a link you've bookmarked stops working, that's the most likely reason; go back to the Department's current list rather than assuming online renewal disappeared entirely.

Most counties still accept renewal by mail, and it's a reasonable option if you can't get to the tax collector's office and your county has no online system (or you'd rather not use it). The general pattern, illustrated with Jackson County's own published process as one concrete example: mail your renewal notice or the vehicle's identifying information along with payment to the tax collector's mailing address — Jackson County's is a post office box (P.O. Box 998, Pascagoula, MS 39568-0998), which is typical of how these offices handle mail, though the exact address is different in every county. A personal or cashier's check is the standard mail-in payment method; cash is obviously not something you'd want to mail.

Neither Jackson's page nor the other county pages checked for this article spell out a single statewide mail-in form — the renewal notice itself, or a note with your tag number, VIN or title number, generally serves that purpose. If you're not sure your county still processes renewals by mail, or what exactly to include, a phone call to the tax collector's office avoids a payment sitting unprocessed.

Every county tax collector's office accepts in-person renewal, and it's the only channel that works everywhere regardless of what online or mail options your county does or doesn't offer. Based on the two county examples checked for this page:

Bring whatever identifies your vehicle to the office — your renewal notice, tag number, title number or VIN — plus your payment. In person is also the only channel where you walk out with your actual tag and decal in hand, rather than waiting for it to arrive by mail.
