Montana requires you to register your vehicle within 30 days of moving to the state or purchasing it there

Registration happens through your county's Department of Motor Vehicles office, not a central state agency. You'll need proof of ownership (the title or bill of sale), proof of Montana residency, and a completed process form. The process takes about 15 to 30 minutes in person, though some counties now accept mail-in registration for renewals. Registration fees vary by county and vehicle type, typically ranging from $50 to $150 for a standard passenger vehicle.

Montana does not require a vehicle inspection before registration, which sets it apart from many neighboring states. You do need to show proof of liability insurance — the minimum is $25,000 per person and $50,000 per accident for bodily injury. Your insurance company can provide this proof in writing or electronically.

What documents you need to bring

Start with proof of ownership. If you bought the vehicle from a dealer, you'll have a temporary registration document and a title process. If you bought it privately, you need a bill of sale signed by both you and the seller, or the title itself if the seller has already signed it over to you. If you're transferring registration from another state, bring your out-of-state title or registration.

Next, bring proof that you live in Montana. A utility bill, lease agreement, or mortgage statement dated within the last 60 days works. Your driver's license alone is not enough. You'll also need your proof of insurance — a declarations page from your insurance company showing your name, vehicle identification number (VIN), and coverage amounts. Finally, bring a completed process for Vehicle Registration (Form MV-14), which you can read from the Montana DMV website or pick up at your county office.

How to find your county DMV office and hours

Montana has 56 counties, and each one runs its own registration office. The Montana DMV website lists all county offices with their addresses and phone numbers. Some larger counties like Yellowstone and Missoula have multiple locations. Call ahead before you go — many rural offices have limited hours, and some are closed on certain days of the week.

If you cannot visit in person, some counties accept mail-in registration for renewals, but not for initial registration. Contact your county office directly to ask whether they accept mail-in applications and what additional documents they require. Processing by mail typically takes two to four weeks.

Registration fees and what they cover

Montana registration fees depend on your vehicle's age and type. A new or recent passenger vehicle typically costs $50 to $150 for a two-year registration. Older vehicles may cost less. Trucks, motorcycles, and recreational vehicles have different fee structures. Your county office can quote you an exact amount before you pay.

Your registration covers two years. You'll receive registration plates (license plates) and a registration card to keep in your vehicle. If you're registering a vehicle you already own and have plates for, you may be able to keep your existing plates if they're in good condition. Ask your county office whether plate replacement is required or optional.

Proof of insurance requirements

Montana law requires all registered vehicles to carry liability insurance. The minimum is $25,000 per person injured and $50,000 per accident. You must show proof of this insurance when you register. Your insurance company will provide a declarations page or a proof-of-insurance letter — either document works.

If you don't yet have insurance, you'll need to purchase it before you can complete registration. Many insurance companies can issue a proof-of-insurance document when ready after you buy a policy, even online. You don't need to wait for a physical policy to arrive in the mail.

Registering a vehicle you bought out of state

If you bought a vehicle in another state and are now moving to Montana, you'll need to transfer your registration. Bring your out-of-state title or registration, proof of Montana residency, proof of insurance, and the completed Montana process form. Some states' titles require a notarized signature from the seller; check your title to see whether it's already signed over to you or whether you need the seller to sign it.

If your out-of-state title is a lien title (meaning a lender holds it), contact your lender to ask how to transfer it to Montana. Some lenders will send the title directly to the Montana DMV; others will send it to you first. This process can add one to two weeks, so start it as soon as you know you're moving.

What happens if you register late

If you don't register within 30 days of moving to Montana or buying a vehicle there, you're driving unregistered. Montana law allows law enforcement to stop you and issue a citation. The penalty is typically a fine of $50 to $100 for a first offense, though it can be higher if you're stopped again.

If you're stopped, you can still register at that point — the officer will not prevent you from doing so. However, you may face the fine regardless. If you've missed the important date, go to your county DMV office as soon as you can and bring all required documents. There is no additional fee for late registration beyond the standard registration cost.

Frequently Asked Questions

Can I register a vehicle online in Montana?

No. Montana does not offer online registration for new vehicles. You must register in person at your county DMV office or by mail if your county accepts mail-in renewals. Some counties are piloting online renewal for existing registrations, so call your county office to ask whether this option is available to you.

What if the vehicle title is in someone else's name?

The person whose name is on the title must sign it over to you, and that signature must be notarized in most cases. Once the title is signed and notarized, bring it to your county DMV office along with your other documents. If the title holder is not present, ask your county office what additional paperwork they need — some accept a power of attorney or a bill of sale in addition to the signed title.

Do I need to register a vehicle I'm only keeping in Montana temporarily?

If you're staying longer than 30 days, yes. If you're visiting for less than 30 days, you can drive on your out-of-state registration. If your stay extends beyond 30 days, you must register before that important date even if you plan to leave later.

What if I buy a vehicle from a private seller who doesn't have the title?

Contact the Montana DMV directly. If the seller lost the title, they can request a duplicate from the county where the vehicle was last registered. You'll need to wait for that duplicate before you can register. If the title is held by a lender, the seller must contact the lender to have it released. This process can take several weeks, so do not plan to register when ready after purchase.

Can I register a vehicle with an out-of-state driver's license?

No. You must have a Montana driver's license or state ID to register a vehicle in Montana. If you're new to the state, get your Montana license first — you have 30 days to do so. Bring your out-of-state license, proof of residency, and proof of Social Security number to your local Driver Services office. Once you have your Montana license, you can register your vehicle.
