Montana vehicle registration starts with the county treasurer's office in the county where you live, not a state DMV office

Montana has no central Department of Motor Vehicles. Instead, each of Montana's 56 county treasurers handles vehicle registration for residents in that county. You'll register your vehicle where you live, not where you buy it or where the dealer is located. The process is the same across all counties, but hours and wait times vary by location.

You can register a vehicle in person at your county treasurer's office, by mail, or online through the Montana Motor Vehicle Division website if your county participates in online registration. Not all counties offer online registration yet, so check your county treasurer's website first to see what methods are available where you live.

Key Takeaways

  • Montana registration happens at your county treasurer's office, and you must register in the county where you live, not where you buy the vehicle.
  • You need the vehicle title, proof of ownership, proof of residency, and a completed process form — the specific documents vary slightly depending on whether the vehicle is new, used, or out-of-state.
  • Registration fees in Montana are based on the vehicle's age and type, and you can find the exact fee for your vehicle on the Motor Vehicle Division website before you go in.
  • If you buy a vehicle from a dealer, the dealer may handle the paperwork and send it to the county treasurer on your behalf, but you remain responsible for completing registration within 14 days of purchase.
  • Montana registration is valid for one or two years depending on your choice, and renewal notices are mailed to your address on file about 30 days before expiration.

Documents you need to bring or mail

The exact documents depend on whether your vehicle is new, used, or coming from out of state. For a used vehicle purchased in Montana, bring the signed title, a bill of sale or purchase agreement, proof of residency (utility bill, lease, or mortgage statement dated within 90 days), and a completed process for Vehicle Registration (Form MV-14). If the title is held by a lender, bring the lien release or a letter from the lender stating the lien will be released.

For a vehicle purchased out of state, bring the out-of-state title, proof of residency, the bill of sale, and Form MV-14. If the vehicle is new and has never been titled, bring the manufacturer's certificate of origin, proof of residency, and the completed process. Some county treasurers also require a vehicle inspection before registration if the vehicle is new to Montana or if the odometer reading cannot be verified.

You can read Form MV-14 from the Montana Motor Vehicle Division website or pick it up at your county treasurer's office. Bring the original title or a certified copy — photocopies are not accepted. If you are registering the vehicle in a business name rather than your personal name, bring documentation showing your authority to register it that way, such as articles of incorporation or a business license.

Registration fees and how they are calculated

Montana registration fees are based on the vehicle's age and type. Passenger cars, pickup trucks, and vans are charged differently from motorcycles, trailers, and commercial vehicles. The fee schedule is updated annually and posted on the Motor Vehicle Division website, where you can look up the exact fee for your vehicle by year, make, and model before you register.

You also pay a one-time title fee when you register a vehicle for the first time in Montana. The title fee is a flat amount that does not change based on the vehicle's value. If you are transferring a title from another state, you pay both the title fee and the registration fee. Renewal fees are lower than initial registration fees and are charged each time you renew.

Montana allows you to register a vehicle for either one year or two years. Two-year registration costs more upfront but saves you a trip to the county treasurer's office the following year. You can choose which option works best for your situation when you register or renew.

Registration timeline and when you must complete it

You have 14 days from the date of purchase to register a vehicle in Montana. If you buy from a dealer, the dealer may submit the paperwork to the county treasurer on your behalf, but you are still responsible for making sure registration is completed within that 14-day window. If you buy from a private seller, you must take the title and documents to the county treasurer yourself.

Processing time at the county treasurer's office is usually one to three business days if you register in person or by mail. Online registration, where available, may be processed the same day. The county treasurer will mail your registration certificate and new license plates to your address on file. If you need plates when ready, some county treasurers will issue temporary plates in person while your permanent plates are being made.

Renewal notices are mailed about 30 days before your registration expires. You can renew by mail, in person, or online (if your county offers it) up to 90 days before expiration. If you miss the important date, you can still renew, but you may owe a late fee in addition to the renewal fee.

Dealer registration and what happens if the dealer handles it

Many Montana dealers will submit your registration paperwork to the county treasurer as part of the sale. The dealer collects your documents, fills out the process, and sends everything to the treasurer's office. You still need to provide the proof of residency and sign the process, but you do not have to go to the county treasurer yourself.

Even if the dealer handles the paperwork, you remain responsible for making sure registration is completed within 14 days. If the dealer does not submit the paperwork or if there is an error, you could be driving an unregistered vehicle. Ask the dealer for a receipt or confirmation that the paperwork has been submitted, and follow up with your county treasurer if you do not receive your registration certificate and plates within two weeks.

Some dealers charge a documentation fee for handling registration paperwork. This fee is separate from the registration fee charged by the county treasurer and is negotiable at the time of purchase. Ask about this fee before you sign the purchase agreement.

Out-of-state vehicles and transfers

If you move to Montana with a vehicle registered in another state, you must register it in Montana within 30 days of establishing residency. Bring your out-of-state title, proof of Montana residency, a bill of sale or purchase agreement, and Form MV-14 to your county treasurer. You will pay both a title fee and a registration fee, and your out-of-state plates are no longer valid once you register in Montana.

Some states do not issue titles for older vehicles or certain types of vehicles. If your out-of-state vehicle does not have a title, bring a bill of sale, proof of ownership (such as an insurance policy or registration from the previous state), and a completed Form MV-14. The county treasurer may require a vehicle inspection to verify the vehicle identification number and condition before issuing a Montana title.

If you are moving out of Montana, you do not need to cancel your Montana registration. Your registration remains valid until it expires. If you sell the vehicle to someone else in Montana, the new owner must register it in their name at their county treasurer's office.

License plates and special registration options

Montana issues standard white license plates with the state name and a county number. When you register a vehicle, you receive two plates (front and rear) unless you register a motorcycle or trailer, which require only one plate. Plates are mailed to your address on file and usually arrive within two to three weeks.

Montana offers several special registration options, including personalized plates, disabled person plates, and veteran plates. Personalized plates cost more than standard plates and must be requested when you register or renew. Disabled person and veteran plates are issued at no extra cost if you meet the requirements and provide the necessary documentation (such as a disabled person parking permit or military discharge papers).

If your plates are lost, stolen, or damaged, you can request replacements from your county treasurer. There is a fee for replacement plates, and they are mailed to you. If you need plates when ready, some county treasurers will issue temporary plates in person.

Frequently Asked Questions

Can I register my vehicle online in Montana?

Some Montana counties offer online registration through the Motor Vehicle Division website, but not all do. Check your county treasurer's website to see if online registration is available in your county. If it is, you can complete the entire process from home and have your registration mailed to you.

What if I buy a vehicle from a private seller instead of a dealer?

You must take the signed title, bill of sale, proof of residency, and completed Form MV-14 to your county treasurer's office yourself. You have 14 days from the purchase date to register it. Private sales do not involve a dealer, so there is no one to submit the paperwork for you.

Do I need a vehicle inspection before I can register in Montana?

Most used vehicles do not require an inspection. However, vehicles new to Montana, vehicles with no title history, or vehicles where the odometer reading cannot be verified may need an inspection. Your county treasurer will tell you if an inspection is required when you bring in your documents.

What happens if I register my vehicle late?

You can still register a vehicle after the 14-day important date, but you may owe a late fee in addition to the registration fee. Driving an unregistered vehicle is illegal in Montana. If you are delayed, contact your county treasurer to find out what the late fee is and complete registration as soon as possible.

Can I transfer my Montana registration to a new vehicle?

No. Each vehicle must be registered separately. When you buy a new vehicle, you register it as a new registration. Your old registration remains valid for the old vehicle until it expires or you sell the vehicle. If you sell the old vehicle, the new owner must register it in their name.
