A Missouri temp tag is a paper permit that lets you legally drive a newly purchased vehicle for 30 days while you finish titling and registration. You buy it at a Missouri license office for $14 total, or you get one from the dealer at the time of sale. It cannot be renewed, and if you already own plates you can transfer to the new vehicle, you may not need one at all.
When You Don’t Need a Temp Tag
If you traded in a vehicle or already own a car you plan to stop driving, Missouri lets you move those plates to the new vehicle. The transfer fee is $2, and you get the same 30-day window to complete registration while driving legally on the old plates. If the new vehicle has a higher horsepower or gross weight rating, you also pay a prorated difference in registration fees.
A temp tag is the answer for buyers who have no existing plates to transfer. That covers most first-time buyers and anyone who sold a previous car without keeping the plates.
How Long the Permit Lasts
The standard temp tag is valid for 30 days from the date of purchase. The clock is firm. The permit cannot be renewed, and it cannot be transferred to another vehicle.
Two dealer-issued versions run longer:
- A 60-day permit is issued when a dealer sells you a vehicle under a written agreement to deliver the certificate of ownership within 30 days after delivery. This is governed by Section 301.210.
- A 90-day permit is issued by dealers operating under Section 301.213, who handle titling and registration on your behalf.
Whichever version you receive, the expiration date printed on the permit is the hard deadline.
What to Bring to the License Office
For a private-party purchase, gather the following before your visit:
- Proof of ownership: the certificate of title signed over to you by the seller, or a Manufacturer’s Statement of Origin for a new vehicle.
- Proof of insurance: a current insurance identification card (original, copy, or legible electronic version). Missouri’s minimum liability coverage is $25,000 per person for bodily injury, $50,000 per accident for bodily injury, and $25,000 for property damage. Trailers are exempt.
- Safety inspection certificate no more than 60 days old, or no more than 90 days old if performed by a Missouri dealer within 60 days before the sale date. Vehicles within their first ten model years with fewer than 150,000 miles on the odometer are exempt from the safety inspection.
- Bill of sale. The Department of Revenue provides Form 1957 for this purpose.
Bring the vehicle identification number and the exact purchase price too, since the clerk uses both to process the transaction and calculate tax.
If the vehicle was previously titled in another state, Missouri may require a physical VIN inspection before issuing permanent plates. That is separate from the temp tag process, but ask about it when you pick up your permit so it does not eat into your 30 days.
What It Costs
The temp tag itself is $5 for the permit plus a $9 processing fee at the license office, for $14 total.
The larger bill comes when you apply for permanent title and registration. At that point you owe state sales tax of 4.225% on the purchase price minus any trade-in allowance, plus local sales tax based on where you live. You also pay titling fees and registration fees based on horsepower or weight. Budget for those alongside the $14, not after it.
Buying From a Dealer vs. a Private Seller
A licensed Missouri dealer can sell you the permit on the spot, and each dealer may issue only one permit per vehicle sold. Many dealers handle the full titling process, which is why dealer-issued permits can run 60 or 90 days.
Buying from another individual means visiting a Missouri license office in person. The clerk verifies your VIN, insurance, and ownership paperwork, and you leave with the paper permit that day. Missouri does not currently offer an online option for private-sale temp tags.
How to Display the Tag
Place the permit on the rear of the vehicle where a regular license plate would go, in or on the rear plate bracket. Do not tape it inside the rear window. The expiration date and VIN must be fully visible and unobstructed.
Missouri requires temp tags to be weather-resistant and nontearing, but road grime and sun exposure still fade them. A clear protective sleeve helps. To a patrol officer, an illegible permit looks the same as no permit, and that is enough for a stop.
What Happens if It Expires
Driving after the expiration date means operating an unregistered vehicle, which is a Class B misdemeanor in Missouri. The Department of Revenue also imposes a late registration penalty that starts at $25 and increases by another $25 for every additional 30 days late, up to a $200 maximum.
Combined with potential court costs from a traffic citation, the total climbs fast. There is no extension, no second temp tag, and no grace period. If you cannot make the deadline, stop driving the vehicle until you complete permanent registration.
