Who Can Legally Sell a Gun in Illinois
Under federal law and Illinois law, most adults who legally own a firearm may sell it privately. However, the seller bears responsibility for not transferring to a prohibited person.
To legally sell a firearm, a person generally must:
- Be legally eligible to possess firearms under federal law
- Be at least 21 years of age
- Not be engaged in the business of dealing firearms without a federal FFL
- Sell only to buyers who are eligible to receive firearms
Federal law prohibits certain individuals from possessing or transferring firearms. A seller who knowingly transfers to a prohibited person commits a serious federal crime.
A seller must not transfer a firearm to persons who:
- Have been convicted of a felony
- Have been convicted of a domestic violence misdemeanor
- Are subject to a qualifying restraining or protective order
- Are unlawful users of or addicted to controlled substances
- Have been adjudicated mentally defective or committed to a mental institution
- Are under 21 years of age
- Are illegal aliens or have renounced U.S. citizenship
Knowingly selling to a prohibited person is a serious federal crime — punishable by up to 10 years in prison and fines up to $250,000. Always verify the buyer’s eligibility.
Understanding these requirements is the essential first step before selling any firearm in Illinois. GunTransfer performs a background check on all buyers and generates a bill of sale that protects the seller.

Selling a Gun Through a Licensed Dealer in Illinois
Typical process when selling through a dealer:
Selling through a dealer means you are not responsible for vetting the buyer — the FFL handles all required background checks. It is the simplest way to ensure a fully compliant transfer in Illinois.
How to Sell a Gun Privately in Illinois
While private firearm sales are permitted in Illinois, all private transfers must go through a licensed FFL dealer for a background check. Direct person-to-person transfers without a dealer are illegal in Illinois.
Private firearm sales are common when:
- Selling a used firearm to another gun owner
- Selling inherited firearms
- Selling to a friend, family member, or collector
Both buyers and sellers remain responsible for complying with federal firearm laws. The seller must not knowingly transfer to a prohibited person. GunTransfer performs a background check on the buyer and documents the transfer with a legally sound bill of sale.
Although Illinois requires the transfer to go through a licensed FFL dealer, many sellers use GunTransfer to create a clear record that ownership has transferred — protecting them from future liability.

Step-by-Step
Step-by-Step Guide on How to Sell a Gun in Illinois
The process for legally selling a firearm in Illinois generally includes the following steps.
1
Confirm your eligibility to sell
Make sure you are legally permitted to possess and transfer firearms under federal and Illinois law.
2
Assess the firearm’s value
Research fair market value using online guides or get a local dealer appraisal.
3
Find a qualified buyer
Locate a buyer through personal contacts or local channels. Both parties must meet at a licensed FFL dealer to complete the transfer.
4
Verify buyer identity and age
Request a valid government-issued photo ID. Confirm the buyer is at least 21 years old. The FFL dealer will verify identity as part of the background check process.
5
Document the transfer with a bill of sale
Use GunTransfer to generate a bill of sale recording both parties, the firearm description, serial number, sale price, and date. GunTransfer also performs a background check on the buyer.
6
File your copy
Store your signed GunTransfer bill of sale securely — it is your permanent proof that the firearm left your possession on a specific date, critical if it is ever questioned.
Why Many Sellers Use GunTransfer
Private firearm sales are permitted in Illinois, but without documentation there is no proof that ownership transferred — leaving the original owner potentially connected to any future incident involving the firearm.
Document the firearm’s serial number and full description
Record the exact date ownership transferred away from you
Protect yourself from future liability if the gun is later misused
Demonstrate responsible, law-abiding gun ownership
For sellers, a documented GunTransfer bill of sale is proof the firearm left your hands on a specific date — which can be critical if the gun is later lost, stolen, or involved in an incident. GunTransfer makes this documentation simple for every private sale in Illinois.
Documents Recommended When Selling a Gun in Illinois
Illinois requires all private transfers to go through a licensed FFL dealer. The dealer retains required records, but a separate GunTransfer bill of sale is strongly recommended. A complete bill of sale should include:
- Seller's full legal name, address, and signature
- Buyer's full legal name, address, date of birth, and signature
- Firearm description: make, model, caliber, and serial number
- Date of transfer and agreed sale price
- Buyer eligibility acknowledgment (confirming the buyer is not a prohibited person)
GunTransfer.com performs a background check on the buyer and generates a complete, state-specific bill of sale in minutes. Both parties sign and each receives a copy — creating a lasting record that the firearm legally changed hands in Illinois.
Waiting Periods and Registration in Illinois
Illinois requires a waiting period of 72 hours for handguns; 24 hours for long guns for firearm sales. The buyer cannot take possession until this period has elapsed after the sale is approved.
Illinois also does not require firearm registration for private citizens. Sellers are not required to report a private sale to the state.
Use the waiting period to complete all required documentation through GunTransfer.
Interstate Gun Sales
- You cannot sell a handgun directly to a buyer in another state in a private transaction — it must go through an FFL dealer in the buyer's state.
- Long gun sales across state lines are subject to the laws of both states — the buyer's FFL dealer handles the transfer.
- For any online sale to an out-of-state buyer, arrange shipment to a licensed FFL dealer in the buyer's state and use GunTransfer to document the transfer.
Illinois Gun Laws Every Seller Should Understand
Although Illinois has specific private sale laws, sellers should understand these important regulations before completing any transfer:
- You cannot sell to any prohibited person under federal law — doing so is a serious federal crime regardless of whether a background check was conducted
- You cannot sell to anyone under 21 years of age
- ALL private transfers must go through a licensed FFL dealer for a background check
- Selling a stolen firearm is a crime under both state and federal law
- If you regularly sell firearms for profit, you must obtain a federal FFL — unlicensed dealing is a federal felony
- Illinois has an assault weapons ban — certain firearms cannot be sold or transferred within Illinois
- Illinois has a 15-round magazine limit — magazines over this capacity cannot be sold or transferred
Responsible Private Firearm Sales
Selling a firearm responsibly means more than following the law — it means taking reasonable steps to ensure the gun goes to a safe, qualified buyer. Responsible sellers should:
Verify the buyer’s government-issued photo ID
Use GunTransfer to complete a background check and generate a bill of sale
Know the federal and Illinois laws that apply to private sales
Keep a copy of the GunTransfer bill of sale for your records
GunTransfer.com performs a background check on the buyer and generates a complete bill of sale — including buyer eligibility acknowledgment, firearm details, and both parties’ signatures. Many responsible Illinois gun owners use it every time they transfer a firearm privately.
