What you need to register a car in Montana

To register a car in Montana, you'll need to visit your county clerk's office with proof of ownership, proof of identity, and proof that your vehicle has passed inspection. Montana requires a safety inspection before registration — not an emissions test, but a check that your lights, brakes, wipers, and horn work. You'll also need to pay registration fees, which vary based on your vehicle's age and weight.

The process itself is straightforward: get the inspection done at any authorized Montana inspection station, then take your inspection certificate, title or bill of sale, ID, and proof of residency to your county clerk. They'll process your registration and issue your plates on the spot or within a few days, depending on the office.

Key Takeaways

  • Montana requires a safety inspection before you can register, and you must complete this at an authorized inspection station before visiting the clerk's office.
  • You'll need your vehicle title or bill of sale, a government-issued ID, proof of Montana residency, and your inspection certificate.
  • Registration fees depend on your vehicle's age and weight, and you pay them at your county clerk's office when you register.
  • Each of Montana's 56 counties has its own clerk's office, and you must register in the county where you live or where the vehicle is garaged.
  • If you're registering a vehicle you just bought, you have 30 days from purchase to complete registration before penalties explore.

Getting your vehicle safety inspection

Before you step into a clerk's office, you must have a valid safety inspection. Montana does not require emissions testing statewide, but it does require a safety inspection that covers brakes, lights, windshield wipers, horn, steering, and seatbelts. You can get this inspection at any station authorized by the Montana Department of Transportation — these include many independent repair shops, dealerships, and service stations.

The inspection costs between $10 and $20 depending on the station. When the inspector completes the check, they'll give you a certificate with a control number. This certificate is valid for 30 days, so time your inspection so that you can get to the clerk's office before it expires. If your inspection expires before you register, you'll need a new one.

If your vehicle fails inspection, the station will tell you what needs to be fixed. You can take it to any mechanic to have the work done, then return to any inspection station for a recheck. There's no requirement to use the same station twice.

Documents to bring to your county clerk

Bring your inspection certificate, your vehicle title or bill of sale, a government-issued photo ID, and proof that you live in Montana. Proof of residency can be a utility bill, lease agreement, mortgage statement, or insurance document dated within the last 60 days. If you're registering a vehicle you just bought, bring the bill of sale signed by both you and the seller; if you own the title already, bring that instead.

If the title is held by a lender or lienholder, bring documentation showing that you have permission to register the vehicle. If you're registering a vehicle titled in another state, bring the out-of-state title and a completed process for Montana Title and Registration (Form MV-40), which you can get from your clerk's office or read from the Montana Department of Transportation website.

If someone else is registering the vehicle on your behalf, bring a signed power of attorney document. The person registering must still have a government ID.

Registration fees and how they're calculated

Montana registration fees are based on your vehicle's age and weight. A vehicle that's one year old pays more than a vehicle that's five years old; a heavier vehicle pays more than a lighter one. The state publishes a fee schedule that your clerk will use to calculate your exact cost.

As a rough example, a five-year-old sedan typically costs between $150 and $250 to register for two years, but this varies significantly. A newer vehicle or a truck will cost more. Your clerk can tell you the exact fee before you pay, so ask if you want to know the amount ahead of time.

You'll also pay a one-time title fee if you're getting a new title issued in Montana — usually $10 to $15. If you're transferring an existing Montana title, there's no additional title fee. Some counties add a small county-specific fee on top of the state registration fee.

Where to register: finding your county clerk's office

Montana has 56 counties, and each has its own clerk's office. You must register your vehicle in the county where you live or where you keep the vehicle if you don't live in Montana. If you move to a new county, you'll need to re-register in your new county when your current registration expires.

To find your clerk's office, search online for "[your county name] Montana clerk" or visit the Montana Secretary of State website, which lists all county clerk contact information and hours. Most offices are open Monday through Friday during standard business hours, though some have limited hours on certain days. Call ahead to confirm hours, especially if you're traveling a distance.

If you can't visit in person, some counties allow you to mail in your registration documents, but you'll still need to have the inspection done in person. Call your clerk's office to ask whether they accept mail-in registration and what additional steps you'll need to take.

Timeline and what happens after you register

The entire process — inspection, then registration — typically takes one to two hours if you have all your documents ready. Your clerk will issue your registration certificate and plates on the same day in most cases, though some offices may mail plates to you within a few days.

Montana registration is valid for two years. Your registration certificate will show your expiration date. About 30 days before expiration, you should plan to renew. You can renew by mail, online, or in person, depending on your county's options.

If you buy a vehicle and don't register it within 30 days, you'll face a late fee. If you drive an unregistered vehicle, you can be cited by law enforcement. Keep your registration certificate and plates with your vehicle at all times.

Special situations: new residents, out-of-state titles, and rebuilt vehicles

If you're moving to Montana from another state, you have 60 days to register your vehicle in Montana. Bring your out-of-state title, bill of sale, inspection certificate, and ID. Your clerk will issue a new Montana title and registration. If your out-of-state title has a lien on it, contact your lender to find out whether they need to release it or whether Montana will recognize the existing lien.

If you're registering a vehicle with a rebuilt or salvage title, Montana requires an inspection by the Department of Transportation before you can register it. This is different from the standard safety inspection and must be done at a specific DOT facility. Contact your county clerk for the location of the nearest inspection facility.

If you're registering a vehicle you built yourself or one that's very old, bring documentation of the vehicle's origin and condition. Your clerk can advise you on what paperwork Montana requires for these vehicles.

Frequently Asked Questions

Can I register my car online in Montana?

You cannot complete initial registration online, but you can renew an existing Montana registration online through the Montana Department of Transportation website if your vehicle passes inspection. For a new registration, you must visit your county clerk's office in person with your inspection certificate and documents.

What if I buy a car from a private seller and they don't have the title?

Contact the Montana Department of Transportation to request a duplicate title. You'll need to provide the vehicle identification number (VIN) and proof of ownership, such as a bill of sale signed by the previous owner. This process takes several weeks, so start it as soon as you buy the vehicle.

Do I need to register my vehicle in the county where I work or where I live?

You register in the county where you live or where you keep the vehicle. If you live in one county and work in another, register where you live. If you move, you'll need to re-register in your new county when your current registration expires.

What happens if my inspection certificate expires before I can get to the clerk's office?

You'll need a new inspection. Inspection certificates are valid for 30 days, so schedule your inspection close to when you plan to visit the clerk. If yours expires, go back to any inspection station and get a new one.

Can I register a vehicle that's financed or has a lien on the title?

Yes. Bring documentation from your lender showing that you have permission to register the vehicle. The lien will appear on your Montana title and registration. You can still drive the vehicle normally; the lien just means the lender has a financial interest in it.
