Montana Boat Permit: Complete Registration Guide (2026)

If you are searching for a Montana boat permit, you are probably trying to figure out exactly what documentation you need, how much it costs, and whether Montana is even the right state to register your watercraft. This guide covers all of it, including the actual Montana boat registration process, why so many boat owners choose Montana, and what the Montana boat permit requirements look like in plain English.

Whether you own a bass boat, a pontoon, a personal watercraft, or a full-size yacht, Montana has a straightforward process for getting your vessel titled and registered. By the end of this page you will know exactly what forms to file, what fees to expect, and whether working with a Montana Boat and Yacht Registration Service makes sense for your situation.

Let’s get into it.

Why Do People Register Boats in Montana?

Montana is one of the most boat-owner-friendly states in the country when it comes to registration costs and requirements. The state has no general sales tax, which means when you purchase a boat and register it through Montana, you avoid the sales tax hit that most other states impose at the point of sale. That alone can save thousands of dollars on a high-value vessel.

Beyond the tax savings, Montana registration fees are comparatively low, the titling process is well-established, and the state does not require emissions testing or annual safety inspections for recreational watercraft. For boat owners who keep their vessel in multiple states throughout the year or who own a high-value yacht, those savings stack up fast.

If you are already familiar with the concept of registering a vehicle through a Montana LLC for asset protection and tax avoidance, the same logic applies to boats. A Montana LLC can hold title to a boat on your behalf, and that structure provides a clean separation between you personally and the vessel itself. You can read more about how that structure works in our post about Hidden Perks of a Montana License Plate: A Tax-Saving Edge, which breaks down the broader financial upside of Montana title and registration strategies.

Montana Has No Sales Tax on Boat Purchases

When you buy a boat in Montana or register an out-of-state boat through a Montana entity, there is no state sales tax applied to that transaction. For a $100,000 yacht, that can mean avoiding $6,000 to $10,000 or more in taxes, depending on where you would otherwise register it. This is a fully above-board approach, not a workaround, because Montana simply does not have a sales tax. You can confirm this directly on the Montana Department of Revenue website.

Montana Boat Registration Fees Are Among the Lowest Nationally

Montana uses a flat-rate fee structure for boat registration rather than tying fees to the vessel’s value. Registration fees typically range from around $6 to $24 per year depending on the length and type of watercraft, with additional title fees in the $10 to $15 range. Compare that to states like California or Florida, where annual registration fees on a large boat can run into the hundreds of dollars annually. The official Montana fee schedule is published by the Montana Motor Vehicle Division.

No Annual Inspections or Emissions Testing Required

Montana does not require recreational boats to pass an annual safety inspection or emissions test to maintain their registration. As long as your paperwork is current and your registration card and decals are properly displayed, you are good to go on the water. This is a significant time and cost advantage for owners who keep their boats in states with stricter annual requirements.

Montana Boat Permit Requirements: What You Actually Need

Before you can get a Montana boat permit or registration, there are specific documents and eligibility conditions you need to meet. The requirements are straightforward, but getting the paperwork right the first time saves you delays.

Documents Required to Register a Boat in Montana

To register a boat in Montana, you will generally need to provide the following:

• Proof of ownership, typically a Manufacturer’s Certificate of Origin (MCO) for new boats or a previous state title for used boats
• A completed Application for Certificate of Title for a Motorboat or Sailboat (Form MV7)
• Hull Identification Number (HIN), which functions like a VIN for watercraft
• Proof of Montana residency OR documentation showing the vessel is held by a Montana LLC
• Payment for applicable title and registration fees
• If transferring from another state, the current out-of-state title signed over to the new owner or entity

If you are registering through a Montana LLC, you will also need the LLC’s formation documents, including the Articles of Organization filed with the Montana Secretary of State. The LLC must be in good standing and have a registered agent in Montana.

Hull Identification Number Requirements

Every motorized vessel and any sailboat over 12 feet must have a Hull Identification Number to register in Montana. If you are buying a new boat from a dealer, the HIN is already permanently affixed. If you are registering a homemade boat or a vessel without a proper HIN, you will need to go through a HIN assignment process with the Montana Department of Justice before registration can proceed.

Montana Boat Permit Requirements for Non-Residents

Non-Montana residents can still register a boat in Montana, but typically only by doing so through a Montana LLC. The LLC is a Montana-based entity, so the boat is technically owned by a Montana entity rather than by an out-of-state individual. This is the most common approach used by boat owners across the country who want to take advantage of Montana’s favorable registration environment. If you want help setting that up, see how the registration process works through our service.

How to Register a Boat in Montana: Step-by-Step

Once you have your documents in order, the actual process to register a boat in Montana is manageable. Here is how it typically works from start to finish.

Step 1: Form Your Montana LLC (If Registering as a Non-Resident)

If you do not live in Montana, the first step is forming a Montana LLC. This is a formal business entity registered with the Montana Secretary of State. The LLC will hold the title to your boat. You can handle this yourself by filing Articles of Organization with the Montana Secretary of State’s business portal, or you can use a service like Dirt Legal that handles the entire formation and registration process for you.

Step 2: Gather Your Boat’s Title or Ownership Documents

You will need the original title or Manufacturer’s Certificate of Origin for the boat. If the boat is currently titled in another state, have the current owner sign the title over to your Montana LLC before you submit registration paperwork. Make sure the HIN on the title matches the number physically on the hull.

Step 3: Submit the Application and Fees to the Montana County Treasurer

Montana boat registration is handled at the county level through the county treasurer’s office. You will submit your completed MV7 form, proof of ownership, and payment to the county treasurer in the county where your LLC is domiciled. The Montana County Treasurers directory can help you find the right office. Many boat owners use a registered agent in a specific county, like Missoula or Cascade, to simplify this step.

Step 4: Receive Your Montana Title, Registration Card, and Decals

Once your application is processed and approved, Montana will issue a Certificate of Title in the LLC’s name, a registration card, and numbered registration decals that must be affixed to the hull. Processing times vary by county but typically run one to four weeks for standard applications. Keep the registration card on the vessel whenever it is in use.

Step 5: Maintain Annual Registration and LLC Compliance

Montana boat registration must be renewed annually. In addition, your Montana LLC must file an annual report with the Secretary of State by April 15 each year. You can review those requirements on the Montana LLC Annual Report Filing page. Failing to keep the LLC in good standing can affect the validity of your registration, so staying current is important.

Using a Montana Boat and Yacht Registration Service

For many boat owners, the paperwork, county-level filing, and LLC formation process is a lot to manage on their own, especially if you have never done it before. That is exactly why Montana Boat and Yacht Registration Services exist. These services handle everything from LLC formation to title transfer to annual renewals, so you never have to deal with county offices, confusing forms, or missed deadlines.

What a Professional Registration Service Does for You

A Montana registration service like Dirt Legal will typically handle the following on your behalf:

• Form your Montana LLC with the Secretary of State
• Provide a registered agent address in Montana
• Prepare and submit your title and registration application
• Follow up with county offices on your behalf
• Send you your completed title, registration card, and decals by mail
• Remind you about annual LLC report filings and registration renewals

This is the same process we use when people register their vehicle through a Montana LLC for cars, trucks, RVs, and motorcycles. Boats are handled through the same framework, and the process works the same way regardless of vessel type.

Is It Worth It to Use a Service?

For a high-value boat, the answer is almost always yes. Consider that a professional service typically costs a few hundred dollars in setup fees, while the sales tax you avoid on a $150,000 yacht in a state like California could be $10,000 or more. Even on a moderately priced boat, the math works strongly in favor of Montana registration. The annual maintenance costs are minimal, especially compared to the savings realized upfront.

Register Boats and Recreational Vehicles Together

One underrated benefit of using a Montana LLC structure is that you can register boats and recreational vehicles under the same LLC. If you already have a Montana LLC for your RV or off-road vehicle, adding a boat to the same entity is often straightforward. This keeps your asset protection structure clean and minimizes the number of separate LLCs you need to maintain. Our team regularly helps clients who want to register boats and recreational vehicles together in a single, efficient structure.
