An Illinois Inland Trout Stamp is a small but essential purchase for most anglers who plan to fish for trout away from Lake Michigan. The stamp costs $6.50 for most licensed anglers, but the fishing license itself is a separate expense. Before heading out, you also need to check the current season, harvest limit, and rules for the specific lake, pond, or stream.
Quick Answer
An Illinois Inland Trout Stamp costs $6.50 for most licensed anglers and $0.50 for Illinois residents age 75 or older. It is required, in addition to a fishing license, when fishing for trout in inland Illinois waters. Lake Michigan trout and salmon require the separate Lake Michigan Salmon Stamp.
Key Takeaways
- The standard annual Illinois Inland Trout Stamp costs $6.50.
- Licensed Illinois residents age 75 or older can purchase the stamp for $0.50.
- A fishing license is normally required in addition to the stamp.
- The Inland Trout Stamp does not replace the Lake Michigan Salmon Stamp.
- Illinois does not sell the Washington-style paid Two-Pole Endorsement described in the original article.
- The statewide daily harvest limit for the Catchable Trout Program is five trout, but site-specific rules may be stricter.

Understanding the Illinois Trout Stamp Cost
The standard annual Illinois Inland Trout Stamp costs $6.50. A licensed Illinois resident who is 75 or older can purchase the stamp for $0.50. These prices are listed in the 2026 Illinois Fishing Information guide.
The stamp is normally an add-on rather than a complete fishing permit. Most anglers must first have a valid Illinois sport fishing license and then add the Inland Trout Stamp if they plan to fish for trout in inland waters.
| Stamp | Standard Fee | Where It Applies |
|---|---|---|
| Inland Trout Stamp | $6.50 | Fishing for or taking trout from inland Illinois waters |
| Lake Michigan Salmon Stamp | $6.50 | Fishing for or taking trout and salmon from Lake Michigan |
The reduced rate for licensed Illinois residents age 75 or older is $0.50 for either stamp. License and stamp fees are subject to change, and a transaction fee may apply when purchasing through the licensing system.

What the Inland Trout Stamp Covers
The Inland Trout Stamp supports participation in Illinois trout fishing outside Lake Michigan. It is commonly needed at lakes, ponds, and streams included in the Illinois Catchable Trout Program.
The Illinois Catchable Trout Program stocks rainbow trout for spring and fall fishing opportunities. A stamp does not guarantee that a water is open, stocked, or available for harvest on the day you visit. Anglers must still follow the program calendar and the rules posted for that location.
The Illinois Department of Natural Resources reports stocking more than 80,000 rainbow trout for the spring program and another 80,000 for fall fishing opportunities.
Inland Waters Versus Lake Michigan
The Inland Trout Stamp is not the correct stamp for Lake Michigan trout and salmon fishing. Anglers targeting those fish in Lake Michigan generally need a Lake Michigan Salmon Stamp instead.
If your trip includes both Lake Michigan and an inland stocked trout water, you may need both stamps. Check the current digest before purchasing so you select the correct products.
Catch-and-Release Requirements
A stamp may still be required when you intend to release every trout. IDNR states that anglers participating in the designated early catch-and-release season must have a valid fishing license and Inland Trout Stamp unless they qualify for an exemption.
Note: Catch-and-release does not automatically remove the license or stamp requirement. The angler’s exemption status and the rules for the specific program or water determine what is required.
Who Needs an Illinois Trout Stamp?
Most resident and nonresident anglers who must hold an Illinois fishing license also need an Inland Trout Stamp when fishing for trout in inland Illinois waters.
Standard Requirement
You generally need both of the following:
- A valid Illinois sport fishing license
- A valid Illinois Inland Trout Stamp
The stamp should be obtained before you begin fishing for trout. Keep accessible proof of your license and stamp while fishing.
Common Exemptions
According to current IDNR guidance, anglers who are not required to obtain a sport fishing license are also exempt from the trout and salmon stamp requirement. Common examples include:
- Resident and nonresident anglers younger than 16
- Qualifying blind or disabled anglers
- Illinois residents fishing while on qualifying active-duty military leave
Other narrow license exemptions may apply. Review the exemption section of the current Illinois Fishing Information guide rather than assuming that age, veteran status, property ownership, or disability automatically qualifies.
Warning: Carry any documentation required to prove an exemption. An exemption from one license product does not necessarily waive every site permit, access fee, reservation, or local requirement.
How to Purchase the Illinois Trout Stamp
You can purchase the Inland Trout Stamp through the Illinois licensing system or from an approved license vendor. The process usually takes only a few minutes.
- Confirm the water you plan to fish. Determine whether it is an inland trout water or Lake Michigan.
- Check your license status. Make sure your fishing license covers the dates of your trip.
- Choose the correct stamp. Select the Inland Trout Stamp for inland trout fishing or the Lake Michigan Salmon Stamp for Lake Michigan trout and salmon.
- Complete the purchase. Pay online or visit an approved vendor.
- Keep proof available. Save or print the license document so it can be shown when required.
Use the official IDNR License, Permit and Registration information page to reach the online system or locate an approved vendor.
Pro Tip: Download a copy of your license document before traveling to a fishing area with weak cellular service. Also verify that the correct stamp appears on the document before leaving the vendor or closing the online purchase screen.
Illinois annual fishing licenses normally expire on March 31. License sales for the new cycle begin March 1, so check the expiration date rather than assuming the license remains valid for one full year from the purchase date.

Illinois Trout Season Dates and Limits
The Inland Trout Stamp does not allow trout harvest outside the open season. The Illinois Catchable Trout Program has separate spring and fall periods, and selected locations may offer early catch-and-release fishing.
| 2026 Rule or Date | Details |
|---|---|
| Early spring catch-and-release | Began March 21 at selected program sites; all trout had to be released immediately. |
| Regular spring opener | April 4, generally beginning at 5 a.m.; individual site hours may differ. |
| Fall closed period | Trout harvest is closed from October 1 until the fall opener. |
| Regular fall opener | Under the statewide third-Saturday rule, the 2026 opener is October 17, generally at 5 a.m.; confirm the official fall announcement and site hours. |
| Daily harvest limit | Five trout per angler unless a stricter site rule applies. |
During an early catch-and-release period, trout must be returned to the water immediately. Harvest may begin only when the regular season opens at that location.
Warning: Not every stocked site opens at 5 a.m., and access can change because of local hours, construction, weather, stocking conditions, or property-management decisions. Check the current IDNR program page and the site operator’s notice before traveling.
Two-Pole Fishing Rules in Illinois
Illinois does not sell the paid Two-Pole Endorsement described in the original version of this article. That endorsement and its $20.23 fee are associated with Washington State, not Illinois.
Under Illinois statewide sport-fishing rules, a licensed angler may generally use no more than two untagged sport-fishing devices under the angler’s immediate control. However, this does not mean that two poles, three hooks per line, or every fishing method are allowed at every trout water.
Individual waters may have rules such as:
- Two-pole-and-line fishing only
- A maximum number of hooks or lures per pole
- Artificial-lure or bait restrictions
- Catch-and-release-only periods
- Area closures or restricted fishing hours
Use the official IDNR Places to Fish resources and the current fishing digest to check the water you plan to visit.
Note: There is no extra Illinois endorsement fee simply for using a second pole where two-pole fishing is permitted. The applicable statewide and site-specific fishing rules still control.
Total Cost: Fishing License Plus Trout Stamp
The trout stamp is only one part of the cost for anglers who also need a sport fishing license. The following examples use the fees listed for the 2026–2027 Illinois license cycle.
| Angler and License | License | Inland Trout Stamp | Combined Cost |
|---|---|---|---|
| Illinois resident, annual license | $15.00 | $6.50 | $21.50 |
| Illinois resident age 65–74, annual license | $7.75 | $6.50 | $14.25 |
| Illinois resident age 75 or older, annual license | $1.50 | $0.50 | $2.00 |
| Nonresident, annual license | $31.50 | $6.50 | $38.00 |
| Nonresident, three-day license | $15.50 | $6.50 | $22.00 |
These totals do not include a possible transaction fee, local access fee, parking charge, or site permit. Anglers who already have a valid fishing license normally need to pay only for the appropriate stamp.

Before You Fish: Illinois Trout Checklist
Use this checklist before visiting an Illinois trout water:
- Confirm that your fishing license is current.
- Buy the Inland Trout Stamp unless an exemption applies.
- Use the Lake Michigan Salmon Stamp instead when targeting Lake Michigan trout or salmon.
- Confirm whether the site is part of the spring or fall Catchable Trout Program.
- Check whether the water is open for harvest or catch-and-release only.
- Verify the site’s opening time, access hours, bait rules, pole limit, and hook limit.
- Know the five-trout statewide daily limit and follow any stricter local limit.
- Keep proof of your license, stamp, and exemption documentation available.
Regulations and stocked-site lists can change. The current Illinois Fishing Information guide and official site notices control if they differ from a general summary.
Frequently Asked Questions
Do I need an Illinois trout stamp for catch-and-release fishing?
Yes, in most cases. IDNR requires anglers participating in the designated early catch-and-release trout season to have a valid fishing license and Inland Trout Stamp unless they qualify for an exemption.
Do children need an Illinois Inland Trout Stamp?
Resident and nonresident anglers younger than 16 are generally exempt from the Illinois sport fishing license and trout stamp requirements. They must still follow season, harvest, method, and site rules.
Do nonresidents need an Illinois trout stamp?
Yes. A nonresident who must hold an Illinois fishing license generally needs the same $6.50 Inland Trout Stamp when fishing for trout in inland Illinois waters.
Does the Inland Trout Stamp cover Lake Michigan?
No. Anglers fishing for or taking trout and salmon from Lake Michigan generally need the Lake Michigan Salmon Stamp. The Inland Trout Stamp applies to inland Illinois trout waters.
How long is an Illinois trout stamp valid?
The stamp follows the Illinois annual licensing cycle rather than lasting for 12 months from the purchase date. A stamp issued for the 2026 license year expires March 31, 2027.
Can I use two fishing poles in Illinois?
Illinois does not require a paid Two-Pole Endorsement. Statewide rules generally allow up to two untagged sport-fishing devices under an angler’s immediate control, but a specific lake, pond, or stream may impose stricter pole, hook, bait, or method limits.
Can I keep trout before the regular season opener?
No. Trout must not be harvested before the regular opener. Fishing may be allowed at selected early catch-and-release sites, but every trout must be released immediately.
What is the Illinois trout daily limit?
The statewide Catchable Trout Program daily harvest limit is five trout per angler. A site may apply a stricter rule, so check the posted regulations before keeping fish.
Conclusion
The Illinois Inland Trout Stamp costs $6.50 for most anglers, but the full cost of a trout trip may also include a fishing license and possible local access charges. Licensed Illinois residents age 75 or older qualify for a reduced $0.50 stamp. Before fishing, confirm whether you need the Inland Trout Stamp or Lake Michigan Salmon Stamp, check the current season status, and review the rules for your exact water.
Illinois does not require the paid Washington-style Two-Pole Endorsement. Where two-pole fishing is allowed, statewide device rules and any stricter site regulations still apply. A few minutes spent checking official guidance can prevent a licensing mistake and help protect Illinois trout-fishing opportunities.
