Illinois Wildlife Code: Licenses, Equipment Rules, and Penalties

The Illinois Wildlife Code, codified at 520 ILCS 5, is the state law that controls how people hunt, trap, and interact with wild animals in Illinois. It gives the Illinois Department of Natural Resources authority to set seasons, bag limits, licensing requirements, and habitat protections, and it backs those rules with penalties that range from petty-offense fines up to $1,000 to Class A misdemeanor fines up to $2,500, along with possible loss of hunting and fishing privileges.¹ Fishing is governed by a companion statute, the Fish and Aquatic Life Code, and the two are enforced together by IDNR conservation police.

What the Code Covers and Who Enforces It

The Wildlife Code hands all wildlife management authority to the IDNR. The department sets the seasons during which animals can be taken, the daily bag and possession limits, and the legal methods for hunting and trapping. There is a ceiling on that authority: the IDNR cannot set a longer season, a larger daily bag, or a larger possession limit than the Code itself allows.¹

The IDNR also acquires and manages land for wildlife, designates refuges and conservation areas, tracks disease and population health, and addresses invasive species. A separate statute, the Illinois Endangered Species Protection Act at 520 ILCS 10, works alongside the Wildlife Code to protect species at risk of disappearing from the state.

Hunting Licenses and Permits

Anyone who hunts in Illinois needs the correct license for the animal they plan to pursue. Under the Wildlife Code, a hunting license is an electronic or physical license authorizing you to take a specific type of animal during a specified period. Trappers need a separate trapping license, and removing problem animals from private property requires a nuisance wildlife control permit.¹

High-demand permits are distributed by lottery. Deer firearm and muzzleloader permits go through three rounds each year. For 2026, the first lottery runs March 3 through April 30 and is limited to Illinois residents. The second, from May 11 through June 30, opens to residents who were not successful in the first round along with nonresidents. A third round from July 13 through August 21 is open to everyone.²

First-time hunters must complete a hunter safety education course before buying a license.

Fishing Licenses and Stamps

A resident fishing license costs $15. Trout anglers in inland waters need an additional Inland Trout Stamp for $6.50, and Lake Michigan salmon anglers need a Lake Michigan Salmon Stamp, also $6.50.³ The stamps fund stocking and habitat work for those specific fisheries.⁴ Some groups are exempt, including residents under 16, residents above a certain age, active-duty military personnel on leave, and anyone fishing on a designated free fishing day. Check the IDNR website for current specifics before you head out.

Equipment and Method Rules

The Code and its administrative rules get specific about what gear is legal. The details matter, because using the wrong equipment during the wrong season is a common way to end up with a citation.

Bow and Crossbow Rules for Deer

During archery deer season, a legal bow is a longbow, recurve, or compound bow with a minimum pull of 30 pounds at some point within a 28-inch draw, and arrows must be at least 20 inches long. Crossbows are legal but must have a minimum peak draw weight of 125 pounds, a minimum length of 24 inches from butt to front of limbs, a working safety, and bolts or arrows at least 14 inches long not counting the point. Other hunting devices are illegal during bow season, and you cannot carry a firearm while bow hunting unless you hold a valid unfilled firearm deer permit during the firearm season or you have a concealed carry license.⁵

Fishing Gear and Snagging

Anglers are limited to one pole and line device with no more than two hooks. Snagging, which jerks a weighted hook through the water to catch fish externally, is restricted to specific species, waterways, and seasons. In the 300-yard zone below locks and dams on the Illinois River, for instance, snagging is allowed from September 15 through December 15 and from March 15 through May 15, with the Peoria Lock and Dam permitting snagging year-round.⁶ Using explosives to take fish is flatly illegal.

Extra Rules for Waterfowl Hunters

Duck, goose, and other migratory bird hunters follow a second layer of federal rules on top of Illinois law. Federal penalties are separate from anything the IDNR imposes.

Every waterfowl hunter aged 16 or older must possess a signed Federal Migratory Bird Hunting and Conservation Stamp, better known as the duck stamp. It is valid from July 1 through June 30 of the following year.⁷ Hunters must also register with the Harvest Information Program before each season. HIP data feeds the federal Harvest Survey, which shapes decisions about season dates, zones, and bag limits.⁸

Federal law prohibits hunting migratory game birds over a baited area if the hunter knows or should know bait has been placed. Standing crops, flooded harvested croplands, and areas where grain was scattered through normal agricultural practices are exceptions, but deliberately spreading corn or feed to attract ducks is not. Lead shot is banned for all waterfowl hunting. Approved nontoxic shot includes steel, bismuth-tin, tungsten-based alloys, and several other compositions, each containing less than one percent residual lead. The rule covers ducks, geese, swans, coots, and any other species in aggregate bag limits during concurrent seasons.⁹

Protected and Endangered Species

The Illinois Endangered Species Protection Act covers both animals and plants. The IDNR maintains the list of endangered and threatened species, and adding or removing a species requires scientific data and expert review. Because the Act reaches plants too, disturbing a protected plant population on public land can create legal exposure just as harming a protected animal would.

Penalties for Wildlife Code Violations

Penalties are tiered by offense severity, and the fines alone can surprise people who assume wildlife citations are minor.

Petty offenses, including some licensing infractions, are punishable by fines up to $1,000.
Class B misdemeanors, such as certain unlicensed fishing offenses, carry fines up to $1,500.
Class A misdemeanors can result in fines up to $2,500.
Business offenses, including commercial fishing violations, can result in fines between $1,000 and $5,000.

Any violation of the Wildlife Code, Fish and Aquatic Life Code, or IDNR administrative rules can also result in revocation of licenses and permits and suspension of privileges.¹⁰ Restitution may be added on top, meaning you pay the replacement value of illegally taken wildlife in addition to the fine.

Endangered Species Violations

Harming, possessing, or selling an endangered or threatened species triggers penalties under the Illinois Endangered Species Protection Act. When the total value of the species involved is less than $300, the offense is a Class A misdemeanor. Penalties escalate for higher-value species or repeat violations.

License Revocation

The IDNR can revoke hunting and fishing licenses for repeated or egregious violations, and revocation can be temporary or permanent depending on the offense and your history. People convicted of poaching or other serious crimes against wildlife may face a lifetime ban.¹⁰

Federal Lacey Act Exposure

When illegally taken wildlife crosses state lines, the federal Lacey Act adds another layer of consequences. Transporting, selling, or purchasing wildlife taken in violation of Illinois law can bring up to five years in federal prison and fines of up to $250,000 for individuals or $500,000 for corporations when the market value exceeds $350. Below that threshold, criminal penalties can still reach one year in prison and $100,000 in fines. Civil penalties of up to $10,000 apply when a person should have known the wildlife was illegally taken. Vehicles, firearms, and other equipment used in the offense can be seized and forfeited.¹¹

Out-of-State Violations Follow You Home

Illinois participates in the Interstate Wildlife Violator Compact. Member states recognize suspensions imposed by any other member state and treat them as if they had occurred at home. If you are convicted of a wildlife offense in another compact state, or fail to comply with a citation there, that state reports the outcome to Illinois, and Illinois initiates its own suspension. A deer-poaching conviction in Missouri or Indiana can cost you your Illinois hunting privileges. You have the right to appeal, typically by requesting an administrative hearing within 30 days of the denial.¹²

Defenses if You’re Cited

People charged with wildlife violations do have defenses. Lack of intent is the most common. If you accidentally exceeded a bag limit due to a genuine miscount, you can argue there was no willful violation, and that argument carries more weight if you reported the mistake promptly rather than waiting for an officer to discover it.

Challenging the evidence itself is another route. If a conservation officer conducted an unlawful search or seizure without proper authority or probable cause, the evidence collected may be excluded. Illinois administrative rules state that evidence is admissible only if it was not obtained from an unlawful search.¹³ Procedural errors during a stop or citation can also provide grounds for dismissal or reduction of charges. Wildlife enforcement is still subject to constitutional protections, and a lawyer familiar with the Code can tell you whether your facts support one of these defenses.
