Illinois is one of the most regulated states in the country for private gun sales — and 2026 brought new changes to the FOID system. Every buyer must hold a valid Firearm Owner's Identification (FOID) card just to possess a firearm or ammunition. As a private seller, you are legally required to verify the buyer's FOID card through the Illinois State Police online portal before completing any transfer. There is also a mandatory waiting period — 72 hours for handguns, 24 hours for long guns. This Bill of Sale documents the agreed price, the FOID verification, and the transfer date — your private record that the state's paperwork does not replace.

💡 Illinois State Police Compliance
Illinois private sales require the seller to verify the buyer's FOID card through the ISP online portal — the approval is valid for 30 days. You must also keep a record of the sale for a minimum of 10 years. As of January 1, 2026, new FOID rules require immigration documentation for non-citizen applicants, and a combined FOID/CCL card is now authorized. The waiting period is different for different firearms — 72 hours for handguns, 24 hours for rifles and shotguns — and it is held to the minute from the time of agreement. Illinois is also one of the few states where open carry is completely illegal with no exceptions. The Protect Illinois Communities Act (PICA), enacted in January 2023, banned assault weapons and magazines over 10 rounds for rifles and 15 rounds for handguns — this ban is currently being challenged in the 7th Circuit with the DOJ itself arguing the law is unconstitutional. Suppressors are completely banned in Illinois.
🚫 Severe Class 4 Felony Risks for IL Sellers
- Not verifying the buyer's FOID card through the ISP portal before the transfer — verbal confirmation is not enough. You must use the online portal and receive approval before handing over any firearm.
- Getting the waiting period wrong — it is 72 hours for handguns but only 24 hours for long guns. The clock starts at the exact time of agreement and is held to the minute.
- Not keeping records for 10 years — Illinois law requires private sellers to maintain a record of every firearm sale for a minimum of 10 years. This Bill of Sale is that record.
- Selling an assault weapon or high-capacity magazine — PICA banned assault weapons and magazines over 10 rounds for rifles and 15 rounds for handguns in January 2023. Transferring banned items privately is a felony.
- Assuming the FOID exemption for medical marijuana users applies — Illinois state law does not revoke FOID cards for medical marijuana license holders, but federal law still prohibits marijuana users from possessing firearms. This creates a legal gray area that buyers and sellers should be aware of.
- Forgetting that open carry is completely illegal in Illinois — there is no open carry provision, not with a FOID card, not with a CCL, not anywhere in public.
Illinois Firearm Transfer FAQ
How do I verify a buyer's FOID card in Illinois?
Sellers must use the ISP Person-to-Person Transfer portal. You enter the buyer's FOID number and date of birth to receive an approval number. This number is valid for 10 days and must be recorded on your Bill of Sale.
What is the waiting period for firearms in Illinois?
Illinois has a mandatory 72-hour waiting period for all firearms—handguns, rifles, and shotguns. The clock starts once the agreement to purchase is made, even in private transactions. Failure to observe this is a violation of 720 ILCS 5/24-3.
Can I sell high-capacity magazines in Illinois?
No. Under the Protect Illinois Communities Act, it is generally illegal to sell or transfer magazines holding more than 10 rounds for long guns or 15 rounds for handguns. Verify your magazines' capacity before listing them in a private sale.
Do I need to keep records of the sale?
Yes. Illinois law requires private sellers to keep a record of the transfer for at least 10 years. This Bill of Sale, along with the ISP approval number, fulfills your legal obligation to document who you sold the firearm to and when.
Related Forms & Regional Compliance:
Illinois stands as a strict regulatory contrast to its Midwestern neighbors. While Indiana, Missouri, and Iowa have all adopted permitless carry and have no FOID requirements, Illinois continues to tighten its borders against unregulated transfers. Neighboring Wisconsin also lacks a FOID system, making it critical for Illinois sellers to remember that selling to a resident of any neighboring state without a licensed FFL dealer is a federal felony.
