Montana Fishing License Requirements: What Every Angler Needs to Know
May 5, 2026

Montana’s rivers and lakes rank among the finest fishing destinations in North America, drawing anglers from every corner of the country to chase wild trout, paddlefish, and walleye across Big Sky Country. But before you rig up your rod and step into the current, you need to make sure your paperwork is in order.
Montana’s licensing system is a stacked, three-part structure — and missing any one piece can land you in serious legal trouble. This guide breaks down exactly who needs a license, what it costs, where to buy it, and what happens if you skip it, so you can spend more time fishing and less time guessing.
Who Is Required to Have a Fishing License in Montana
A valid fishing license is required for all types of fishing on state waters for anyone 12 or older. That rule applies to both residents and out-of-state visitors without exception. A fishing license allows a person to fish for and possess any fish or aquatic invertebrate authorized by the state’s fishing regulations, and it is nontransferable and nonrefundable.
Anyone aged 12 or older must hold a valid Conservation License, an Aquatic Invasive Species (AIS) Prevention Pass, and a Base Fishing License before casting a line on any state water. These three components work together as a package — you cannot legally fish with just one of them.
To qualify as a resident angler, the bar is specific. To be a legal resident eligible to purchase a resident Fishing License, you must have physically been living in Montana for at least 180 consecutive days immediately before purchasing any resident license, must file Montana state income tax returns as a resident if required to file, must have registered your vehicles in Montana, and may not possess or apply for any resident hunting, fishing, or trapping privileges in another state or country.
Key Insight: Montana’s licensing system uses a stacked model — every angler must first secure a Conservation License before any fishing license can be purchased or considered valid.
If you plan to fish inside Yellowstone National Park in addition to Montana state waters, note that fishing permits for Yellowstone National Park are separate from a Montana fishing license. Yellowstone National Park fishing permits are still sold directly through park fly shops and visitor centers, issued by the National Park Service and not part of Montana’s online system. If you plan to fish inside Yellowstone National Park and outside park boundaries in Montana, you will need both licenses.
Types of Fishing Licenses Available in Montana
Most anglers over the age of 12 need two licenses in order to fish in Montana. These include a Conservation License and a Base Fishing License that is available for 2 days, 10 days, or the full season. On top of those two, the AIS Prevention Pass is mandatory for all anglers.
Here is a breakdown of the main license types available to both residents and nonresidents:
- Conservation License — Before you buy any fishing or hunting license in Montana, you need a Conservation License. This is non-negotiable — it is the foundation that every other license is built on. A Conservation License includes the State Lands Recreation Use Permit, which covers a combination of fishing, hunting, and trapping.
- Base Fishing License (Full Season) — This license is valid from March 1 to the end of February the following year. It covers most trout, whitefish, and warmwater species.
- Short-Term Licenses — There are two options for this type of license. One is good for two consecutive days and the other for 10 consecutive days. These are popular choices for visiting anglers on a shorter trip.
- AIS Prevention Pass — All anglers need to purchase an Angler Aquatic Invasive Species Prevention Pass (AISPP) to fish in the state. Montana’s Legislature initiated this program in 2017 to protect the state’s waters from invasive species.
- Combination Licenses — There are Resident Sportsman and Nonresident Combination licenses that include a fishing license for the season. These can be a cost-effective option if you plan to hunt as well.
Whether you are planning a weekend float on the Madison or a full week on the trout waters of Montana, matching the right license duration to your trip length is the first decision to make.
Pro Tip: The 5-day nonresident license is widely considered the best value for visiting anglers. At $73.50 total, it covers a full week of fishing far more efficiently than buying individual days.
Freshwater vs. Saltwater License Requirements in Montana
Montana is a landlocked state with no ocean coastline, which means there are no saltwater fishing license requirements to worry about. From cold to warm waters, crystal-clear mountain lakes to big rivers, Montana has everything a freshwater enthusiast could wish for. Every fishing license issued by Montana Fish, Wildlife and Parks (FWP) applies exclusively to freshwater fishing.
Montana is divided into three fishing districts: Western, Central, and Eastern. In the Western District, rivers and streams are generally open from the third Saturday in May through November 30, while lakes and reservoirs are open all year. In the Central and Eastern Districts, rivers, streams, lakes, and reservoirs are typically open year-round, unless specified otherwise.
The district you fish in matters beyond just season dates. Bait rules, gear restrictions, and species-specific regulations all vary by district. For example, in the Western District, no live fish may be used as bait, though other live bait such as worms, leeches, and insects are permitted in waters not restricted to artificial lures.
If you enjoy different types of fishing — from ice fishing on reservoirs to fly fishing on blue-ribbon streams — your single Montana fishing license covers all of them, provided you are fishing in legal waters during open seasons and following district-specific regulations.
Important Note: Always check the specific water you plan to fish against the Exceptions to Standard Regulations in the FWP regulations booklet. Special regulations on rivers like the Big Hole, Madison, and Ruby can change from year to year and override district-wide rules.
Fishing License Costs in Montana
As of March 1, 2026, Montana fishing license fees are as follows. All figures below are sourced from the Montana FWP 2026 licensing fee schedule and third-party sources verified against that schedule.
| License Type | Conservation License | Base Fishing License | AIS Pass | Total |
|---|---|---|---|---|
| Resident Adult (18–61), Full Season | $8 | $21 | $2 | $31 |
| Nonresident (16+), Full Season | $10 | $100 | $7.50 | $117.50 |
| Nonresident (16+), 2-Day | $10 | $14 | $7.50 | $31.50 |
| Nonresident (16+), 10-Day | $10 | $49 | $7.50 | $66.50 |
| Resident with Disability | $8 | $10.50 | $2 | $20.50 |
| Resident Blind (Lifetime) | Not required | $10 (one-time) | $2/year | $10 + $2/yr |
The 2026 license year runs from March 1, 2026, through February 28, 2027. Youth aged 12–17 need youth-priced licenses, which are significantly cheaper than adult rates — check the current FWP fee schedule at fwp.mt.gov for the exact youth pricing tiers by age group.
Note that the price of items purchased through the online service includes a 2.9% plus $0.30 per transaction service fee. Budget for that small addition when purchasing online.
If you are also planning a bass fishing trip in Montana, your standard fishing license covers warmwater species like bass — no separate stamp is needed for those.
Exemptions From Fishing License Requirements in Montana
Several groups are either fully exempt from Montana’s fishing license requirements or qualify for significantly reduced fees. Knowing which category applies to you can save money and simplify your trip planning.
Children Under 12
Anyone 11 years old or younger is not required to have a fishing license, including a Conservation or AIS Prevention Pass. This is the broadest exemption and applies to all children regardless of residency.
Free Fishing Weekends
By Montana law, each year on Mother’s Day and Father’s Day weekends, any person — resident or nonresident — may fish for any fish within the state without obtaining a Fishing License, as long as they abide by the seasons, restrictions, and bag limits listed in the Fishing Regulations. The two exceptions are paddlefish and bull trout, both of which require a Conservation, Fishing, and AIS Prevention License regardless. Montana FWP typically designates Free Fishing Weekends each year on Mother’s Day and Father’s Day weekends. Watch the official FWP website for the 2026 free fishing weekend announcements.
Purple Heart Recipients and Legion of Valor Members
The state gives military veterans with a Purple Heart and/or Legion of Valor Medal the privilege to fish with just a Conservation License, regardless of their residency status and age. You will need to provide verification of your Purple Heart and DD 214 Form, or a Legion of Valor membership card, to qualify for this exemption.
Residents with Disabilities
There is a special Montana Resident with a Disability Conservation License available. In order to qualify for this license, Montanans need to be permanently and substantially disabled. Residents with disabilities can also purchase other licenses at a discounted price.
Visually Impaired Residents
Visually impaired Montana residents can apply for a Lifetime Fishing License for the Blind. You will need to apply directly with the Department of Fish, Wildlife, and Parks (FWP) and provide them the necessary medical certification. A Conservation License is not required with this permit.
VA Hospital Patients and State Institution Residents
Permits are available for patients residing at VA Hospitals and residents of State institutions, except the State penitentiary. These free permits are available on-site at the VA Hospital or State Institution.
Educational Events and Fishing Clinics
Free fishing license exemptions are available to qualified educational events and fishing clinics for a specific date and location. In general, the event must be educational in nature and instruct participants on fish identification, regulations, ethics, fishing techniques, and water safety. It must be held at times and locations that do not substantially conflict with other recreationalists, must be taught under the guidance of an FWP employee or certified fishing instructor, and must not be part of a profit-making activity.
Add-On Stamps, Permits, and Endorsements in Montana
Your base fishing license covers most species in Montana, but certain fisheries require additional permits before you can legally target them. These are not optional — fishing for regulated species without the correct add-on is treated as a separate violation.
Paddlefish Tag
All anglers must purchase a paddlefish tag. The cost is $6.50 for residents and $15 for nonresidents. Harvest-only tags for the Upper Missouri River are available through a lottery draw. Montana has three unique paddlefish seasons, and anglers may select only one area to fish for paddlefish. A paddlefish permit is required if you are heading to the Yellowstone or Missouri rivers near Glendive or Fort Peck during the spring snagging season — one of Montana’s most unique fisheries.
Bull Trout Catch Card
A free Bull Trout Catch Card is required for the specific waters where angling for bull trout is permitted, such as Lake Koocanusa and Hungry Horse Reservoir. All other waters are closed to intentional fishing for bull trout. These fisheries are very restrictive because bull trout are listed as a threatened species under the Endangered Species Act. Catch cards are free but must be obtained before you fish those designated waters.
Lake Trout Tags
Some waters with specific lake trout management may require tags — check the regulations for Flathead Lake specifically. Always pull up the current Montana Fishing Regulations booklet at fwp.mt.gov before fishing a new water.
Pro Tip: Paddlefish tags for the Upper Missouri River lottery draw are in high demand. Apply early through the FWP online system — spots fill quickly during the spring snagging season near Glendive and Fort Peck.
If you enjoy fly fishing for trout on blue-ribbon rivers, your base fishing license covers rainbow, brown, brook, and cutthroat trout in most waters. Just verify the specific regulations for the river you are targeting, as catch-and-release rules and artificial-lure-only restrictions apply to many of Montana’s most famous stretches.
How to Buy a Fishing License in Montana
Montana’s licensing system changed significantly in 2026. Beginning March 1, 2026, Montana fishing licenses are no longer available for in-person purchase. All licenses must now be purchased online through Montana Fish, Wildlife and Parks. This is a permanent shift, not a temporary change.
Montana’s licensing system had been operating on outdated infrastructure for years, with hardware and software built on older technology that was no longer supported or repairable. The transition allows Montana Fish, Wildlife and Parks to modernize license management, simplify reporting requirements, and improve data tracking for conservation.
Here is the step-by-step process to buy your license for 2026:
- Go to the Montana FWP Online Licensing System at ols.fwp.mt.gov
- Create an account or log in to your existing FWP account if you have had a Montana fishing license before.
- Add your Conservation License to the cart first — this must come before any other license.
- Add your AIS Prevention Pass.
- Select your Base Fishing License type — full season, 10-day, or 2-day.
- Complete payment (credit/debit card required; no cash options exist online), then save your digital license by downloading it as a PDF, taking a screenshot, or storing it in the MyFWP app.
Some businesses participate as License Ambassadors, helping customers complete the online purchase process, but the transaction itself runs through FWP’s portal. You can find a License Ambassador near you through the FWP website if you need in-person assistance navigating the online system.
Important Note: Cell service near many of Montana’s premier rivers is unreliable. Do not plan to buy your license streamside on the morning of your trip. Purchase your license at least a few days before you leave home and download a copy to your phone or print a backup.
Licenses are checked regularly by wardens, and digital licenses on your phone are fully legal and accepted during checks. The MyFWP app stores your license offline, which is especially useful in areas with no cell coverage.
Anglers heading to other states after their Montana trip can find similar licensing guides for Colorado fishing license requirements, Wyoming fishing license requirements via our Wyoming trout season guide, and Indiana fishing license requirements to stay compliant wherever you cast.
Penalties for Fishing Without a License in Montana
Montana takes fishing violations seriously, and the penalties reflect that. Getting caught on the water without proper licensing is not a minor inconvenience — it is a criminal matter.
In Montana, fishing without a license is a misdemeanor under MCA 87-2-109. A first offense carries a fine of up to $1,000, up to 6 months in county jail, or both. Courts can and do impose license suspension periods on top of fines, meaning you do not just pay a fine and walk away. You could lose your ability to legally fish or hunt in Montana for years or even indefinitely.
If FWP wardens catch you fishing illegally, they are also looking at whether you are in possession of fish taken unlawfully — which triggers separate charges under Montana’s criminal fish and wildlife code.
Most fish and game violations are misdemeanors punishable by a fine not to exceed $1,000 and imprisonment for not longer than six months. The court may also order the forfeiture of any current hunting, fishing, and trapping licenses and the privilege to hunt, fish, and trap, or use state lands for recreational purposes for a period set by the court.
Violations involving invasive species carry even steeper consequences in 2026. New for 2026, AIS violation fines have been significantly increased under new state law. A first negligent offense now carries nearly double the previous fine. Knowingly attempting to introduce invasive species — a felony — now carries fines up to $25,000. Failing to stop at an AIS inspection station when required can result in a fine of up to $500.
Taking too many fish also comes with financial consequences beyond the standard misdemeanor. Taking an over-limit of fish will result in a fine plus restitution to the state for each fish over the limit. Restitution for bull trout may be up to $500 per fish, and for river arctic grayling, white sturgeon, and paddlefish, restitution is $300 per fish.
Common Mistake: Many visiting anglers assume they can pick up a license at a fly shop or sporting goods store on the morning of their trip. As of March 1, 2026, that is no longer possible. All licenses must be purchased online before you reach the water.
Spring is prime warden season in Montana. As ice breaks up on reservoirs and lakes across the Hi-Line and the Missouri River drainage starts dropping into fishable shape, FWP game wardens concentrate heavily at public access points, boat ramps, and popular wade-fishing stretches. Wardens do not need a reason to check your license beyond the fact that you are fishing. It is a routine, legal stop, and they conduct them constantly during high-traffic periods.
The simplest way to avoid all of this is to buy your license before you leave home. The cost of a valid license is dramatically less than any violation fine. For anglers curious about how other states handle enforcement and licensing, see our guides on Florida fishing license requirements, Texas fishing license requirements, and California fishing license requirements for comparison.
Montana’s waters are among the most productive and beautiful in the country. Protecting access to them — through proper licensing and compliance — keeps them that way for every angler who follows.
