Registering a boat in Montana is straightforward once you understand which vessels must be registered, how permanent registration works, and which agency handles each step.
Montana uses a permanent (one-time) registration system for most boats. Registration and titling are processed through the Montana Motor Vehicle Division (MVD), while boating rules and numbering requirements are overseen by Montana Fish, Wildlife & Parks (FWP).
For non-residents, Montana also permits boat registration through a Montana LLC, provided statutory requirements are met.
Below is a detailed breakdown of the process for registering a boat in Montana.
Which Boats Must Be Registered in Montana?
Montana requires most motorized boats and certain sailboats to be permanently registered and numbered.
According to the Montana FWP boating regulations page and the Montana Boating Rules publication, the following vessels must be registered:
Boats That Require Registration
- Sailboats 12 feet and longer
- All motorboats, including motorized canoes and rubber rafts
- All personal watercraft (PWC / jet skis)
These vessels are subject to permanent registration under Montana Code Annotated § 61-3-321 and must also be properly numbered.
Boats That Are Exempt from Registration
The following vessels are not required to be registered or titled:
- Non-motorized sailboats under 12 feet
- Manually propelled boats (canoes, kayaks, rowboats, paddleboards), regardless of length
- Lifeboats for a vessel
- Government-owned boats
For plain-language explanations of these requirements, educational resources such as Boat-Ed’s Montana registration guide provide additional summaries consistent with state rules.
How Montana Boat Registration Works (Permanent Registration)
Montana does not use annual boat registration renewals for most vessels. Instead, the state applies a one-time permanent registration fee based on vessel length.
The official Montana MVD watercraft registration page outlines this structure.
One-Time Registration Fees
The permanent registration fee schedule is:
- Under 16 feet: $65.50
- 16 feet to under 19 feet: $125.50
- 19 feet and over: $295.50
These are one-time fees paid at registration. There is no yearly renewal through the county treasurer for permanently registered boats.
Additional county processing fees may apply depending on the filing method or local administration.
Titling Requirements
Boats that are required to be registered must also be titled, meaning the owner will receive a Certificate of Ownership (title).
The title confirms ownership and is issued through the Montana MVD as part of the registration process. Exempt vessels do not require titling
Step-by-Step: How to Register a Boat in Montana
Step 1: Gather Required Documents
A typical registration packet includes:
- Proof of ownership (Manufacturer’s Certificate of Origin, previous title, or bill of sale)
- Completed application for boat registration and titling
- Hull Identification Number (HIN)
- Vessel details (year, make, model, length, hull material)
- Valid identification for the owner or authorized agent
If the vessel does not have a Hull Identification Number, Montana FWP can assign one for a $5 fee. The number must be permanently affixed to the vessel and inspected by officials.
Several independent guides, including Boaters Secret Weapon and Pack N Ride, outline similar documentation requirements consistent with Montana MVD procedures.
Step 2: Submit Application to the Proper Office
Boat registration and titling are handled through the county treasurer’s office (Motor Vehicle Division).
Montana Fish, Wildlife & Parks oversees numbering rules and boating regulations but does not issue titles.
Depending on the county, applications may be submitted in person or by mail. Always confirm procedures with the specific county office before filing.
Step 3: Pay Permanent Registration Fees
At the time of submission, the applicable length-based permanent registration fee must be paid in accordance with Montana Motor Vehicle Division requirements.
Montana uses a one-time registration structure for qualifying vessels, meaning there are no annual renewal fees once the boat is permanently registered.
Additional county processing fees may apply depending on the filing location. If a third-party service is used to assist with registration or titling, separate service or expedited handling fees may also apply. These are independent of state-mandated registration fees.
Step 4: Receive Title and Registration Numbers
Once processed, the owner receives:
- Certificate of Ownership (Title) – when required
- Certificate of Number (Registration)
- Assigned registration numbers for display on the bow
Montana previously required validation decals; however, Montana FWP now states that boats are no longer required to display validation decals.
To operate on Montana waters, vessels must display proper registration numbers and carry required documentation onboard.
Registering a Boat in Montana as a Non-Resident (Montana LLC Option)
Many non-residents explore Montana boat registration through a Montana limited liability company (LLC).
Montana permits non-residents to form an LLC in the state. That LLC can own and register vehicles, including boats.
How the LLC Structure Works
- Form a Montana LLC by filing Articles of Organization.
- Appoint a registered agent with a Montana address.
- Purchase or retitle the boat into the LLC’s name.
- Submit the boat registration and titling application under the LLC.
- Pay the permanent watercraft registration fee.
Once completed, the boat is titled and registered in the LLC’s name, not the individual’s name.
Permanent Registration for LLC-Owned Boats
If the boat meets the size threshold (motorized vessels and sailboats 12 feet or longer), it will receive permanent registration under Montana’s statutory structure.
The one-time fee model still applies.
Frequently Asked Questions

In Montana, boats that are required to be registered are typically also required to be titled. Titling establishes documented ownership through a Certificate of Ownership issued by the Montana Motor Vehicle Division.
