How to Sell a Gun in Illinois

2026 Complete Legal Guide

Selling a firearm in Illinois is legal for most law-abiding adults, but the process must follow both federal law and Illinois state regulations. This guide covers what private sellers need to know to sell legally and responsibly.

How to Sell a Gun in Illinois — Quick Overview

  • Who Can Sell: Most law-abiding adults who legally own a firearm may sell it in Illinois
  • Private Sales: Require a background check through a licensed FFL dealer
  • Background Check: Required for all transfers — must go through a licensed FFL dealer
  • Waiting Period: 72 hours for handguns; 24 hours for long guns
  • Prohibited Transfers: Cannot sell to anyone under 21 or any person prohibited under federal law
  • License Required: Only if you regularly sell for profit (federal FFL required)
  • Gun Registration: Not required — no need to report private sales to the state
  • Bill of Sale: Not legally required but strongly recommended — protects the seller from future liability

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.

Age Requirements for Selling a Gun in Illinois

Before completing any gun sale in Illinois, both parties must understand the minimum age requirements.
Selling or trading to a licensed FFL dealer:

21

years old minimum to sell or trade handguns at a dealer

18

years old minimum to sell or trade rifles or shotguns at a dealer
These age requirements apply to all firearm transfers in Illinois. GunTransfer’s bill of sale captures the buyer’s date of birth to help document age compliance and protect the seller.
For private gun sales in Illinois: federal law sets 21 as the minimum age for ALL private firearm transfers. Selling a firearm to anyone under 21 violates federal law — always ask for ID.
Selling directly to a private buyer (private gun sale):

21

years old minimum — all private handgun sales

21

years old minimum — all private long gun sales
Illinois requires a background check for all private firearm sales between eligible adults. GunTransfer’s bill of sale documents the buyer’s date of birth and eligibility acknowledgment — protecting sellers from liability.

Selling a Gun Through a Licensed Dealer in Illinois

Many Illinois residents sell firearms to or through a Federal Firearms Licensee (FFL) dealer, such as a gun store or sporting goods retailer. This is one of the safest options — the dealer handles the buyer’s background check and all required paperwork.

Typical process when selling through a dealer:

1
Bring the firearm to a licensed FFL dealer for appraisal and current market valuation.
2
Choose between a direct cash sale to the dealer or a consignment arrangement.
3
The dealer runs a background check on the buyer — you are not responsible for this step.
4
Complete the dealer’s required paperwork for the transaction.
5
Receive payment once the sale is complete.
6
Ask for a copy of the sale record and keep it for your records.

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 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.

GunTransfer performs a background check on every buyer and generates a complete, legally sound bill of sale — giving both parties documented proof of the transfer.
Using GunTransfer helps sellers:

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.

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.

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
Following these rules helps ensure your private sale in Illinois remains lawful. When in doubt, use a licensed FFL dealer to complete the transfer.

Frequently Asked
Questions

Do I need a license to sell a gun in Illinois?

No. Private sales do not require a federal firearms license. 

Yes. Illinois requires every private firearm sale to go through a licensed dealer, and the dealer runs the background check. However, you must not knowingly sell to a prohibited person. Sellers are not off the hook simply because they didn’t ask — if you had reason to know the buyer was prohibited and sold anyway, you may face criminal liability.
Illinois does not publish an official bill-of-sale form, and a bill of sale is not a substitute for whatever transfer process your state requires — that part is answered above. Some states do put a record-keeping duty on the seller, so check yours before assuming there is none. However, GunTransfer’s bill of sale is strongly recommended — it documents the transfer, includes buyer eligibility acknowledgment, and protects the seller from future liability if the firearm is later misused.
You may advertise a firearm for sale online. However, if shipping to a buyer in another state, the firearm must be transferred through a licensed FFL dealer in the buyer’s state. In Illinois, you cannot. A private sale must go through a licensed dealer, and completing one without a dealer is a criminal offense rather than a technicality.

The Illinois Assault Weapons Ban (PICA) and Who You May Sell To

The Protect Illinois Communities Act took effect on January 10, 2023. Under 720 ILCS 5/24-1.9(b) it is unlawful to knowingly manufacture, deliver, sell, import or purchase an assault weapon, an assault weapon attachment, a .50 calibre rifle or a .50 calibre cartridge, or to cause another to do so.

If you lawfully owned a covered firearm before the Act and want to part with it, Illinois gives you three buyers and no others. The statute and the Illinois State Police agree word for word: such a firearm may be transferred only to an heir, to an individual residing in another state who will maintain it in another state, or to a federally licensed firearms dealer. That is the list. Not to a neighbor, not to another Illinois FOID holder, not on consignment to a private party in-state. If you want cash for it, a licensed dealer is the practical route.

Owners who held covered firearms before the Act were required to file an endorsement affidavit through their FOID account, and the Illinois State Police set that deadline at January 1, 2024. If you did not file one, do not guess at where that leaves you — ask the Illinois State Police directly before you move the firearm anywhere.

Where the law stands. PICA is in force and is being enforced. On July 9, 2026 the Seventh Circuit reversed the district court and ordered judgment entered for the State in Barnett v. Raoul (Nos. 24-3060, 24-3061, 24-3062 and 24-3063), holding 2–1 that the Act’s restrictions are consistent with the nation’s tradition of firearm regulation. The Illinois Supreme Court had already reversed the one state-court judgment against it, and the Illinois State Police state that the Act is enforceable across Illinois.

This remains live. The Barnett challengers obtained an extension to November 6, 2026 to petition the Supreme Court, and separately the Court has granted certiorari in Viramontes v. Cook County (Docket 25-238) — a challenge to the Cook County ordinance rather than to PICA itself — consolidated with the Connecticut case Grant v. Higgins (Docket 25-566) and set for argument on December 2, 2026. Until a court says otherwise, the Act applies to you today.

The Illinois FOID Card Requirement for Private Sellers

Illinois puts the duty on you, the seller. Under 430 ILCS 65/3(a-10), before transferring a firearm to another private party you must either run the transfer through a federally licensed dealer, or contact the Illinois State Police with the buyer’s Firearm Owner’s Identification card number to confirm that the card is valid. There is no third option, and “he showed me his card” is not one of them.

The check is done through the person-to-person transfer function on the ISP FOID/CCL Card Verification Portal at verify.ispfsb.com. You supply your own FOID card or Illinois driver license, plus the make, model and serial number of the firearm; your buyer supplies their FOID. If the card is valid, ISP returns an approval number, and that approval is good for 30 days.

Understand what that check is and is not. The Illinois State Police say so in capitals in their own guidance: the check on the person-to-person portal is not a background check. It confirms that a FOID card is valid, and nothing more. If you want an actual NICS check run on your buyer — and on a private sale to someone you do not know, you should want one — the way to get it is to route the transfer through a dealer instead.

Then there is the 72-hour rule, which lives in the criminal code rather than the FOID Act and catches people out for that reason. Under 720 ILCS 5/24-3(A)(g) it is an offense to deliver a firearm incidental to a sale without withholding delivery for at least 72 hours after the application to purchase is made. The provision is written as “a person,” not “a dealer,” so it reaches you. The listed exceptions are narrow — law enforcement, licensed dealers, certain out-of-state mail order, and long guns at sanctioned competitive shooting events — and there is no exception for family and none for FOID holders generally.

You must keep a record for ten years. 430 ILCS 65/3(b) requires the transferor to keep, for ten years from the date of transfer, the date, a description and serial number of the firearm, the buyer’s FOID number, and the approval number ISP gave you. The buyer does not keep this record — a person who receives a firearm under (a-10) instead lodges a record of the transfer with a licensed dealer within ten days. The ten years are yours.

The family exemption is a gift exemption, and the distinction is the whole thing. 430 ILCS 65/3(a-15)(2) exempts transfers made as a bona fide gift to a listed relative: husband, wife, son, daughter, stepson, stepdaughter, father, mother, stepfather, stepmother, brother, sister, nephew, niece, uncle, aunt, grandfather, grandmother, grandson, granddaughter, father-in-law, mother-in-law, son-in-law or daughter-in-law. A sale to any of those people is not a gift and is not exempt. If your son hands you $400 for the rifle, you are back under (a-10) and you owe the ISP check. Cousins and in-laws beyond those listed are not on the list at all. Note too that the exemption waives the check in (a-10); it does not mention the ten-year record in (b).

A FOID card itself costs $10 and is valid for ten years, subject to automatic renewal in some circumstances.
