License fees and size/bag limits for Idaho are pending verification. Each state sets its own resident and nonresident fees and per-species limits — always confirm with Idaho Department of Fish and Game (IDFG) before fishing.
How the Idaho rules fit together
A Idaho fishing trip is governed by four separate layers, and they are set by different parts of the same agency. The license establishes that you may fish at all. The statewide size, bag, and possession limits set the default for any water not given special treatment. Waterbody-specific regulations override those defaults on named lakes, rivers, and zones. And season and gear restrictions can close a fishery entirely for part of the year or limit it to artificial lures or catch-and-release.
The order matters. Where a specific water has its own rule, the specific rule wins over the statewide default — so a legal statewide limit does not make a fish legal on a special-regulation lake, and a statewide season does not override a closed section of river. Whatever a summary page tells you, the enforceable answer for the water in front of you comes from the current Idaho regulation booklet or the agency’s own site.
Two further layers are easy to miss. A stamp, validation, or report card may be required on top of the license for specific species or waters — you can hold a valid license and still be non-compliant. And aquatic invasive species rules apply to your boat and trailer rather than your catch, which means they can stop the trip at the ramp before a line is ever wet.
Because fees, limits, and seasons are revised annually and often mid-season, treat every number on this page as a starting point dated to the last verification and confirm the current figure with Idaho Department of Fish and Game (IDFG) before you buy a license or keep a fish.

What a Idaho fishing license costs
A resident annual license for Idaho is $30.50, and the non-resident annual license is $108.00 — a difference of $77.50. The non-resident rate is roughly 3.5 times the resident rate — meaning the license is usually the smallest expense in the trip budget.
Short-term options as published: Resident daily first day $13.50 + $6.00 each additional consecutive day; Nonresident daily first day $22.75 + $7.00 each additional consecutive day.
Saltwater: No saltwater stamp (inland state)..
Senior and reduced-rate options: Resident senior (65+) $13.75; resident junior (14-17) $16.00; disabled/DAV $5.75.
Separate aquatic-invasive-species stamp: Invasive Species Fund (ISF) sticker.
Reciprocal border waters to check before travelling: Bear Lake and Snake River (ID border sections).

Size and bag limits tracked for Idaho
Idaho has 10 statewide limits resolved in this tool — Brook Trout, Brown Trout, Common Carp, Crappie, Largemouth Bass, Muskellunge (Muskie), Northern Pike and Rainbow Trout, among 10 in the tracked set. Each entry below carries the agency citation it came from.
Brook Trout: bag 25; season Year-round; Harvest encouraged on many waters.. Citation: Idaho Department of Fish and Game — 2025–2027 Idaho Fishing Rules (Regional daily bag limits).
Brown Trout: bag 6 (lakes); 2 (rivers); combined with trout; season Year-round. Citation: Idaho Department of Fish and Game — 2025–2027 Idaho Fishing Rules (Regional daily bag limits).
Common Carp: bag No limit; season Year-round. Citation: Idaho Department of Fish and Game — 2025–2027 Idaho Fishing Rules (Regional daily bag limits).
Crappie: bag 25; season Year-round. Citation: Idaho Department of Fish and Game — 2025–2027 Idaho Fishing Rules (Regional daily bag limits).
Largemouth Bass: bag 6 (combined with smallmouth; lakes/reservoirs); season Year-round; Many rivers/streams have no bag limit; some regions impose a 12 in minimum.. Citation: Idaho Department of Fish and Game — 2025–2027 Idaho Fishing Rules (Regional daily bag limits).
Muskellunge (Muskie): minimum length 40 in; bag 2 (tiger muskie); season Year-round; Southwest Region standard; none under 40 in.. Citation: Idaho Department of Fish and Game — 2025–2027 Idaho Fishing Rules (Regional daily bag limits).
These are statewide general rules only. Slot limits, special-regulation waters, catch-and-release stretches, and zone-by-zone seasons override them — and a general rule that is absent from this list is not the same as no restriction. Confirm the rule for the exact water you are fishing with Idaho Department of Fish and Game (IDFG) before keeping a fish.
Mandatory harvest reporting in Idaho
Idaho requires mandatory harvest reporting or registration for specific species. The tracked rule set covers salmon/steelhead.
Reporting window: Electronically validate (e-tag) immediately upon harvest. How to report: Salmon/Steelhead permit must be e-tagged in the GoOutdoorsIdaho app immediately upon landing a fish. Citation: IDFG — Salmon/Steelhead Electronic Validation
A reporting requirement usually attaches to the fish, not the license: you can be fully licensed and still be out of compliance for failing to register a tagged or sensitive species within the stated window. Record the tag number and the date before you leave the water.
Free fishing days in Idaho
Reported license-free dates for 2026: June 13, 2026. Most states waive the license only, not the rules — size and bag limits, gear restrictions, seasons, and any required report card still apply, and some states still require a free or zero-cost license to be issued before you fish.
Reported for 2026 by public aggregators and may not match the official state schedule. Always confirm the current year’s dates and any species/stamp exceptions with the agency before planning.
