Mississippi has no DMV, and its dividing line isn’t weight class — it’s the state line. An 80,000-pound dump truck that never leaves the county registers at the county courthouse; any truck over 10,000 pounds that crosses into another state deals with the Department of Revenue. And Mississippi’s 60-day grace period comes with unusually sharp teeth.
Quick answer: Intrastate-only trucks — at any weight — register at your county Tax Collector’s office. Trucks over 10,000 pounds GVW that travel interstate register directly with the Mississippi Department of Revenue at its offices in Biloxi, Clinton, Hattiesburg, Hernando, and Meridian, with IRP filed online through TAP (the Taxpayer Access Point) for same-day temporary credentials. State law bars both channels from issuing a tag on an HVUT-liable truck without proof of payment or suspension.
Where do I register a heavy truck in Mississippi?
The fork is at 10,000 pounds and the state line. In-state-only vehicles register at the county Tax Collector where the truck is domiciled, regardless of weight. Over 10,000 pounds with interstate travel, you register directly with the Department of Revenue — five walk-in offices statewide, with a warning worth heeding: late arrivals may not receive credentials until the next business day.
IRP applications, vehicle additions, and removals all run through TAP, the DOR’s Taxpayer Access Point, where you can file, pay, and receive temporary credentials the same day. Mississippi is a PRISM state — IRP registrants need a USDOT number, TIN, and an MCS-150 updated within the past year.
The statute binds the county clerk too
Mississippi Code section 27-19-62 is explicit: anyone applying “to the commissioner or any county tax collector” for registration of an HVUT-liable vehicle must present proof of payment — or suspension — before registration, and no tag may issue without it. Most county tax collector websites never mention Form 2290, but the law reaches their counters all the same. If your intrastate truck is at 55,000 pounds or more, bring the Schedule 1 to the courthouse.
What proof of HVUT payment does Mississippi accept?
- A copy of the receipted IRS Schedule 1 (Form 2290) listing the vehicle identification numbers; or
- Copies of the Form 2290 with Schedule 1 plus a proof-of-payment document — e.g., the cleared check, front and back.
One thing the Department of Revenue is emphatic about: the 2290 cannot be filed through MDOR. It’s a federal return, filed with the IRS — the state only checks the result. (Suspended low-mileage vehicles still show a Schedule 1; the statute’s own wording covers proof of suspension. See suspended vehicles.)
The 60-day grace is a loan — and Mississippi collects
Proof isn’t required at initial IRP registration for new or used units registered within 60 days of the date shown on the bill of sale. But Mississippi is one of the few states that spells out what happens next: you must deliver the 2290 to the Department of Revenue within 60 days of purchase, “or the IRP Credentials may be canceled” — the checklist version says the license may be revoked. Registering first and filing later is allowed; forgetting to close the loop is not. The federal deadline runs regardless: Form 2290 is due by the last day of the month following first use. See buying a used truck and due dates.

Frequently asked questions
Is there a Mississippi Form 2290?
No. Form 2290 is a federal IRS return — and Mississippi says plainly that it cannot be filed through the Department of Revenue.
My truck never leaves Mississippi — where do I go?
The county Tax Collector, at any weight. The Schedule 1 requirement still applies at 55,000 pounds or more; the statute binds county counters just like state offices.
What happens if I skip the 2290 after the 60-day grace?
Mississippi’s manual is explicit: the IRP credentials may be canceled and the license revoked. Deliver the stamped copy before the window closes.
Can I get credentials the same day?
Yes — file and pay through TAP and temporary credentials issue same-day; walk-ins at the five DOR offices should arrive early.
