Registering a Vehicle in Montana

Montana requires vehicle registration through the local county treasurer's office — not a state DMV — within 60 days of purchase or after establishing residency. The process combines title transfer and registration into a single visit when both are needed, and the absence of a state sales tax means most registrations skip the use-tax calculation that adds hundreds or thousands of dollars in other states. Montana also offers a uniquely flexible permanent registration option for older vehicles.

When you need to register

Montana requires registration in three circumstances:

• New residents with vehicles previously titled in another state — within 60 days of establishing Montana residency.
• Buyers of a new or used vehicle from a private party or out-of-state dealer — within 60 days of purchase.
• In-state dealer purchases — the dealer typically files the initial title and registration paperwork within 30 days; the buyer receives plates and a registration card at delivery.

Driving with expired or out-of-state registration past the 60-day window is a citable offense in Montana; the fine is roughly $200 plus court costs.

Documents required

To register a vehicle at your Montana county treasurer's office, bring:

• Form MV5 — Application for Title and Registration, signed by the buyer (and seller for private-party transfers).
• Form MV1 — Application for Vehicle Registration (combined with MV5 for new registrations).
• The existing title, properly assigned by the seller. For out-of-state vehicles, the title from the prior state.
• A signed bill of sale showing the purchase price, date, and odometer reading.
• A VIN inspection — required for any vehicle previously registered out of state. The inspection is free and can be done by a Montana law enforcement officer or a Montana MVD employee.
• Proof of liability insurance meeting the 25/50/20 minimum — see our Montana car insurance guide.
• An odometer disclosure statement for vehicles less than 10 years old.

Fees

Montana's vehicle fees are flat or weight-based, not value-based:

• Title fee: $12.
• License fee in lieu of property tax: varies by vehicle age — newer vehicles pay more, older vehicles much less.
• Annual registration fee: $87 for passenger cars under 11 years old; declines for older vehicles.
• Lien recording fee: $8 if the vehicle is financed.
• Specialty plates: additional $30-$60 per plate, depending on design.
• County option tax: 0%-0.7% in some counties, applied to vehicle value as part of the registration fee.

Permanent registration option

Montana is the only state offering permanent registration for vehicles. The option is available for vehicles 11 years and older and pays a one-time fee — typically about $87.50 for passenger cars — that registers the vehicle indefinitely with no further renewal required. The plates remain valid as long as the same owner holds the vehicle. The owner still must update their address with the county treasurer if they move, and must transfer the registration if they sell. Trailers can also be permanently registered after they reach the age threshold.

Permanent registration is one of the reasons older vehicles are particularly common in Montana — the long-term cost savings on registration are substantial.

VIN inspection

Any vehicle previously registered outside Montana must pass a VIN inspection before titling. The inspection verifies the vehicle's VIN matches the title and the vehicle hasn't been altered in a way that affects identification. Montana state troopers, sheriff's deputies, county treasurer staff, and Montana MVD employees can sign the VIN inspection form. The inspection is free and typically takes less than 5 minutes. The signed form is submitted with the title and registration application at the county treasurer's office.

New residents from out of state

If you're moving to Montana from another state, you have 60 days from establishing residency to register your vehicle. Montana looks at whether you've taken Montana employment, enrolled children in school, opened Montana bank accounts, or registered to vote in Montana as residency markers. The previous out-of-state title is surrendered with form MV5, and Montana issues new plates and a new title. Out-of-state liens are honored — the prior lienholder's interest stays attached to the Montana title.

No state sales tax

Montana is one of only five states with no statewide sales tax. A vehicle purchase in Montana doesn't carry a use-tax surcharge, which can save buyers thousands of dollars on a typical car compared to neighboring states. Some local resort areas (Big Sky, Whitefish, West Yellowstone, Red Lodge) collect a small resort tax on certain purchases, but vehicles are generally exempt from those local taxes.

County option tax

A handful of Montana counties levy a small county option tax on vehicle registrations — typically 0%-0.7% of the vehicle's depreciated value. The tax is collected at registration and goes to county-level transportation funding. Most counties don't charge the tax; a few that do include Cascade, Lewis and Clark, and Yellowstone. The county treasurer informs you at the time of registration whether the tax applies.
