How to Register a Van Conversion in Montana (2026 Guide)

Montana is one of the most straightforward states in the country for registering a van conversion as a motor home. There is no sales tax. There is no emissions testing. There is no periodic safety inspection. The state’s registration fees are flat, based on vehicle age, and paid at the county level. If your van meets the habitation requirements, the process amounts to a law enforcement inspection, a title application, and a trip to the county treasurer’s office.

This guide covers the registration process for Montana residents who have built or purchased a converted van and want to title it as a motor home. For out-of-state owners considering the Montana LLC strategy, see Montana LLC Registration for Van Conversions.

What Montana Calls Your Van

Montana uses the term motor home, defined in MCA 61-1-101. The statute defines a motor home as a motor vehicle:

Designed to provide temporary living quarters, built as an integral part of or permanently attached to a self-propelled motor vehicle chassis or van
Containing permanently installed independent life support systems that meet the NFPA 1192 standard on recreational vehicles
Providing at least four of the following five types of facilities

That third requirement is the one that determines whether your conversion qualifies.

What Your Van Needs to Qualify

Under MCA 61-1-101, a motor home must include at least four of these five facility types:

Cooking, refrigeration, or icebox (a cooktop and a 12V fridge both count under this single category)
Self-contained toilet (cassette, composting, or fixed)
Heating or air conditioning, or both (a diesel heater qualifies; a rooftop A/C unit qualifies)
Potable water supply, including a faucet and sink (a freshwater tank with a pump, faucet, and basin)
Separate 110-volt or 125-volt electrical power supply or liquefied petroleum gas supply, or both (a shore power inlet with a breaker panel, or a propane system for cooking/heating)

Montana groups cooking and refrigeration into a single facility category. This is different from states like Colorado, which separate them into two of six. The practical result is that a van with a cooktop and a fridge satisfies only one of Montana’s five categories, not two.

Most van conversions built for extended travel or full-time living will meet four of five without difficulty. A build with a cooktop, a composting toilet, a diesel heater, and a sink with a freshwater tank hits exactly four. Adding shore power or a propane system gets you to five.

The word “permanently installed” in the statute matters. Loose camping equipment placed inside a cargo van does not satisfy the definition. The conversion needs to be built in, not set up temporarily.

The statute also references the NFPA 1192 standard for recreational vehicles, which covers electrical, plumbing, and heating system safety. Professional builders typically meet this standard as a matter of course. DIY builders should be aware that the inspecting officer has discretion to evaluate the quality of the installation, and systems that appear unsafe or improperly installed may not pass.

The Registration Process, Step by Step

Montana handles all vehicle titling and registration through the county treasurer’s office in the county where you reside. There is no centralized state DMV office that processes walk-in transactions. The Montana Motor Vehicle Division (MVD) oversees policy and maintains records, but the county treasurer is where you submit paperwork and pay fees.

Step 1: Complete the Conversion

Finish the build to a point where at least four of the five habitation features are installed and functional. The vehicle needs to look like a living space with permanent installations, not a cargo area with loose equipment.

Step 2: Get the Motor Home Inspection Certificate (Form MV95)

This is the step specific to motor home classification. Before you can title a van as a motor home, a Montana peace officer or Department of Justice employee must physically inspect the vehicle and complete the Motor Home Inspection Certificate (MV95).

The MV95 form documents the vehicle’s identification numbers and certifies that the conversion meets the motor home definition under MCA 61-1-101. The inspector verifies which of the five facility types are present and confirms that at least four are permanently installed.

To schedule an MV95 inspection, contact your local law enforcement agency. Some counties handle these through the sheriff’s office; others have specific staff at the county treasurer’s office who can perform or coordinate the inspection. Call ahead, as not every office conducts these on a walk-in basis.

Step 3: Get a VIN Inspection (Form MV20)

If the vehicle has an out-of-state title, or if the identity of the vehicle is in question, a Stage I VIN inspection is also required. This is performed by local law enforcement, driver license exam station staff, or participating county treasurer’s office staff using the Vehicle/OHV Identification Number Inspection form (MV20).

For vehicles already titled in Montana that are being retitled with a body type change (van to motor home), confirm with your county treasurer whether an MV20 is required in addition to the MV95. In many cases, the MV95 inspection covers both the VIN verification and the habitation equipment check.

Step 4: Complete the Title Application (Form MV1)

Fill out the Application for Certificate of Title for a Motor Vehicle (MV1). This is the standard Montana title application. Enter the vehicle information and specify the body type as motor home.

Key sections to complete on the MV1:

Section A: Applicant information (name, address, county of residence)
Section B: Vehicle description (year, make, VIN, body type as motor home)
Section C: Security interest/lien information (if financed)
Section E: Applicant signature and acknowledgment

Step 5: Submit Everything to the County Treasurer

Bring the following to your county treasurer’s office:

Completed MV95 (Motor Home Inspection Certificate), signed by the inspecting officer
Completed MV1 (Application for Certificate of Title)
Completed MV20 (VIN Inspection), if required
Current vehicle title (Montana title or out-of-state title)
Bill of sale, if recently purchased
Valid Montana driver’s license
Proof of insurance
Payment for title, registration, and plate fees

Under MCA 61-3-303, the county treasurer handles both titling and registration. In practice, these are processed as a single transaction when you submit your paperwork.

Fees

Montana’s fee structure for motor homes is simpler than most states. There is no sales tax, no personal property tax on vehicles, and no use tax. Registration fees are flat amounts based on the vehicle’s age, paid as a fee in lieu of tax under MCA 61-3-321(7).

Registration Fees (Annual)

Age of Vehicle	Annual Fee
Less than 2 years old	$282.50
2 years to under 5 years	$224.25
5 years to under 8 years	$132.50
8 years and older	$97.50

All fees above include Montana’s 3% administrative fee per MCA 61-3-111. Vehicle age is calculated by subtracting the model year from the current calendar year.

For motor homes with an MSRP exceeding $300,000 that are 10 years old or less, an additional $800 surcharge applies under MCA 61-3-321(7)(c). This does not apply to most van conversions, where the base vehicle MSRP is well below that threshold.

Permanent Registration

Owners of motor homes that are 11 years old or older may permanently register the vehicle under MCA 61-3-321(7)(b). Permanent registration is a one-time payment that eliminates the need for annual renewal. The fee is:

$237.50 one-time registration fee
$5.15 insurance verification fee (if keeping existing plates)
$12.36 new plate fee (if new plates are being issued)

Permanent registration does not transfer with the vehicle. If the motor home is sold, the new owner must title and register it from scratch and pay all applicable fees.

Other Fees

Fee	Amount	Authority
Certificate of title (original)	$10.30 (includes 3% admin fee)	MCA 61-3-203
Replacement title	$10.30	MCA 61-3-203
Montana Highway Patrol salary and retention fee	$10.30	MVD fee schedule
New license plate set	$12.36	MVD fee schedule
Insurance verification fee	$5.15	MVD fee schedule

Some counties impose a local option motor vehicle tax under MCA 61-3-537, which adds a county-specific amount to the registration. Not all counties have adopted this tax. Contact your county treasurer’s office for the exact total you will owe.

What You Will Not Pay

Sales tax: Montana has no general sales tax. There is no sales or use tax on vehicle purchases, period. This applies to residents and LLCs alike. See Montana Department of Revenue.
Personal property tax on vehicles: Montana uses a fee-in-lieu-of-tax system for vehicle registration, replacing traditional personal property taxation.
Emissions fees: Montana has no emissions testing program.
Safety inspection fees: Montana has no periodic safety inspection requirement.

Inspections and Emissions

Montana does not require emissions testing for any vehicle class. There is no statewide emissions program, no county-level testing requirement, and no smog check at registration or renewal.

Montana also does not require periodic safety inspections. There is no annual or biennial mechanical inspection for registered vehicles. The only inspection involved in the motor home registration process is the MV95 habitation equipment check performed by law enforcement at the time of initial titling.

This combination makes Montana one of the simplest states for ongoing vehicle registration maintenance. Once the motor home is titled and registered, renewals require only the annual fee payment (or nothing further, if permanently registered). There is no recurring inspection obligation.

Insurance After Registration

Once your van is titled as a motor home in Montana, you become eligible for RV and motor home insurance policies that cover the full conversion value, not just the base vehicle. A standard auto policy on a cargo van does not cover the cabinetry, electrical system, plumbing, or interior finish work.

Montana requires liability insurance on all registered motor vehicles. Minimum coverage limits under MCA 61-6-103 are:

$25,000 bodily injury per person
$50,000 bodily injury per accident
$20,000 property damage per accident

These are minimums. Most van conversion owners carry higher limits, particularly if the build has significant value.

See Best Insurance for Van Conversions for a comparison of carriers that write policies on converted vans, including which ones require a motor home title and which will insure builds on a standard auto policy.

The Montana LLC Question

Montana’s lack of sales tax has made it a popular state for out-of-state vehicle registration through LLC formation. If you are a Montana resident registering your own van, the LLC strategy is irrelevant to you. You already benefit from no sales tax by virtue of residency.

If you are reading this guide as part of research into registering a van through a Montana LLC while living in another state, that is a different process with different legal considerations and significant enforcement risk in many states. See Montana LLC Registration for Van Conversions for a detailed breakdown of how the LLC strategy works, what it costs, which states are pursuing enforcement, and what happens when it goes wrong.

Common Pitfalls

Not meeting the four-of-five threshold. Montana groups cooking and refrigeration into a single category. A van with a cooktop, a fridge, and a bed has only one of the five facility types checked. You need four. A toilet, heating, a water system with a sink, and either an electrical system or propane supply will get you there alongside the cooking/refrigeration category.

Assuming any officer can perform the MV95 inspection. The Motor Home Inspection Certificate must be completed by a Montana peace officer or Department of Justice employee. Not every law enforcement office is familiar with the process. Call ahead to confirm availability and scheduling.

Skipping the inspection before visiting the county treasurer. The county treasurer cannot process a motor home title without the completed MV95. Arriving without it means a wasted trip.

Confusing the registration fee with permanent registration eligibility. Permanent registration is only available for motor homes 11 years old or older. Vehicles younger than 11 years must renew annually.

Not confirming county-specific fees. Local option taxes under MCA 61-3-537 vary by county. The state-level fee schedule does not include these. Ask your county treasurer for the full amount before you go.
