The Illinois trapping season for most furbearers runs November 10 through February 15, with beaver and river otter extending through March 31. Before you set a single trap, you need an Illinois Department of Natural Resources (IDNR) trapping license, and depending on what you’re after, you may need additional permits for bobcat or river otter. A resident license costs $10.50. Trapping outside the season, skipping daily trap checks, or using the wrong equipment can land you with a Class B misdemeanor.
Season Dates by Species
The IDNR sets trapping seasons each year. For the 2026–2027 season, muskrat, mink, raccoon, opossum, striped skunk, red fox, gray fox, coyote, badger, bobcat, and weasel share the same window: November 10, 2026 through February 15, 2027.1Illinois General Assembly. 17 Illinois Administrative Code 570 – Muskrat, Mink, Raccoon, Opossum, Striped Skunk, Weasel, Red Fox, Gray Fox, Coyote, Badger, River Otter, Bobcat and Woodchuck (Groundhog) Trapping

Who Needs a License and What It Costs
Anyone trapping furbearers during an open season needs an Illinois trapping license, which is separate from any hunting or fishing permit.3Justia Law. Illinois Code 520 ILCS 5 – Wildlife Code Current fees:
- Resident: $10.50
- Non-resident with state reciprocity: $175.50
- Non-resident without reciprocity: $250.50
Reciprocity depends on whether a non-resident’s home state extends similar privileges to Illinois residents.5Illinois Department of Natural Resources. Trapping Licenses
A handful of groups can trap without a license. Resident landowners living on their farmland, their bona fide tenants, and those individuals’ children may trap on that land during the open season. Illinois residents on active duty in the Armed Forces are exempt, as are residents with a Type 1 or Type 4, Class 2 disability documented by an Illinois Person with a Disability ID card, and certain veterans certified by the VA as at least 10% disabled with a service-related condition, receiving total disability pensions, or former POWs. Exempt trappers still have to follow every other rule: season dates, equipment, species-specific permits, the lot.3Justia Law. Illinois Code 520 ILCS 5 – Wildlife Code
Trapper Education
If you were born on or after January 1, 1998, and have never held an Illinois trapping license, you have to complete a state-approved trapper education course before buying one. The course covers species identification, equipment, and ethics.2Hunt Illinois. Furbearer Trapping Trappers born before that date are exempt.
Youth License
Trappers under 18 can buy a Youth Hunting and Trapping License for $7. No education course is required, but the youth must be accompanied and supervised by a parent, grandparent, or guardian who is at least 21 and holds a valid Illinois trapping license. Completing an approved trapper safety course drops the supervision requirement.6Illinois General Assembly. Illinois Code 520 ILCS 5/3.1-9
Bobcat and River Otter Need Extra Permits
Most Illinois furbearers have no bag limit, but bobcat and otter do, and both come with permit steps people miss.
Bobcat. You need a Bobcat Hunting and Trapping Permit before you try to harvest one. The limit is one bobcat per permit holder per season. After taking a bobcat, you have 48 hours to purchase a Bobcat Registration Permit to document the harvest.2Hunt Illinois. Furbearer Trapping The 48-hour window is strict.
River otter. The otter season runs November 10 through March 31.7Illinois Department of Natural Resources. River Otter Trapping The limit is five otters per person per season. Within 48 hours of trapping each otter, you must purchase an Otter Registration Permit. The IDNR then mails you a federal CITES tag, which must be permanently attached to the green hide before the pelt is exported outside the U.S. or transferred to a fur buyer, tanner, or taxidermist.2Hunt Illinois. Furbearer Trapping
Beaver shares the extended season but has no bag limit and no permit beyond a standard trapping license.2Hunt Illinois. Furbearer Trapping
Daily Trap Checks
Every trap in the field must be visited and all animals removed at least once each calendar day. Failing to check traps daily is a Class B misdemeanor on its own. Illinois does allow remote trap-checking systems in place of a physical visit, but only if the system reports trap status to a centralized database at least once per calendar day, sends closure and health alerts within one hour, and supports on-demand status checks.8Illinois Department of Natural Resources. 17 Illinois Administrative Code 525
Equipment Rules
Trap Size and Placement
Illinois restricts traps mostly by where and how they’re set:
- Foothold traps in water: inside jaw spread cannot exceed 7½ inches.
- Body-gripping traps in water: inside jaw spread cannot exceed 144 square inches.
- Body-gripping traps with a 10-inch jaw spread or larger: must be totally submerged when set.
- Body-gripping traps on land under 49 square inches: allowed only inside a structure at least 4 inches from any outside surface, or set outdoors at least 8 feet above the ground inside an enclosed tube or box where the trigger sits at least 12 inches from any entrance.
Violating these rules is a Class B misdemeanor.8Illinois Department of Natural Resources. 17 Illinois Administrative Code 525
Snares
At least half the loop must be underwater at all times, and the loop diameter cannot exceed 15 inches when set. The cable must be between 5/64 and 1/8 inch in diameter and must include a mechanical lock, an anchor swivel, and a stop device that prevents the loop from closing to less than 2½ inches in diameter. Stainless steel cable is prohibited.9Hunt Illinois. Illinois Digest of Hunting and Trapping Regulations
Trap Identification
Every trap in the field must be inscribed or tagged with the owner’s name and address. Stamped copper or brass tags hold up better than write-on tags, which tend to wear off after a catch or two.
IDNR-Managed Sites
State-owned or state-managed properties often add tighter rules. Some sites allow only dog-proof–style land sets, ban foothold traps during upland game seasons, or require body-gripping traps to be fully submerged regardless of size.10Legal Information Institute. Illinois Code tit. 17, 570.40 – Trapping Regulations on Department-Owned, -Leased or -Managed Sites Check the site’s specific rules before setting anything.
Landowner Permission
You cannot trap on someone else’s property without their permission. That covers the land and any water flowing over or standing on it.9Hunt Illinois. Illinois Digest of Hunting and Trapping Regulations Written permission isn’t technically required by statute, but a handshake can fall apart if a dispute arises, and a signed note protects both parties.
Penalties
Wildlife Code violations fall into three tiers. Any violation not specifically assigned to a higher category defaults to a petty offense, which carries fines but no jail time.3Justia Law. Illinois Code 520 ILCS 5 – Wildlife Code
Most of what trappers actually face sits in the Class B misdemeanor tier: trapping out of season, skipping daily checks, breaking equipment rules, or operating without a valid license. Under Section 3.5, those carry up to a $1,500 fine and up to six months in jail.11Illinois General Assembly. Illinois Code 730 ILCS 5/5-4.5-60 – Class B Misdemeanor
More serious violations become Class A misdemeanors, including trapping while your license is revoked or suspended, possessing illegally taken wildlife, or commercializing wildlife outside permitted channels. A Class A misdemeanor carries up to a $2,500 fine and up to 364 days in jail.12Illinois General Assembly. Illinois Code 730 ILCS 5/5-4.5-55 – Class A Misdemeanor Certain Class A violations also trigger mandatory minimum fines, such as $500 on top of other penalties for specific license and permit violations, and second or subsequent violations of some sections can escalate to a Class 4 felony.3Justia Law. Illinois Code 520 ILCS 5 – Wildlife Code
The IDNR can also suspend or revoke your trapping license. Getting caught trapping during a revocation period automatically bumps the charge up to a Class A misdemeanor.
Federal and Tax Issues to Know About
If you sell or transport pelts across state lines, the federal Lacey Act prohibits the sale, transport, or purchase of any wildlife taken in violation of state law.13U.S. Fish & Wildlife Service. Lacey Act An Illinois violation doesn’t stay an Illinois problem once the pelt leaves the state. River otter pelts are especially sensitive because they require CITES tags before any export or transfer.
Trapping on a national wildlife refuge in Illinois is governed by the U.S. Fish and Wildlife Service rather than the IDNR alone. Whether trapping is allowed is decided refuge by refuge, and refuges that permit it may require a special use permit on top of your state license.14U.S. Fish & Wildlife Service. Trapping All state regulations still apply on refuge land. Contact the refuge manager before setting any traps on federal property.
Money earned from pelt sales is taxable. The IRS generally treats small, irregular earnings as hobby income, reported on Schedule 1, Form 1040, Line 8j, with no expense deductions allowed. If you trap in a businesslike manner, with records, time investment, and an intent to profit, the IRS is more likely to treat it as a business, which means Schedule C, deductible expenses, and self-employment tax.15Taxpayer Advocate Service. Hobby vs. Business Income Cash sales to a fur buyer don’t change that.
