Wisconsin Gun Laws: Complete Guide

Private Sales and Transfers

• A private seller must not knowingly transfer a firearm to someone who is prohibited from possessing one, whether by felony conviction, delinquency adjudication, injunction, or another disqualifying status. Interstate transfers ordinarily must pass through an FFL in the buyer's state, and a person who repeatedly sells firearms for profit may need a federal dealer license regardless of state law. [1][13]
• Wisconsin has no state form or process that converts an otherwise unlawful transfer into a lawful one, and the state's DOJ background-check infrastructure under Section 175.35 applies to dealer handgun sales rather than private transactions. A seller who is unsure about a buyer's residency, age, or eligibility should route the sale through a licensed dealer instead of completing it privately. [12][13]

• Confirm Wisconsin residency, identity, age, and eligibility before completing a private sale. [1][13]
• Use a licensed dealer whenever residency or eligibility is uncertain, or whenever the buyer lives out of state. [13]
• Do not transfer a firearm to a person under eighteen outside the supervised-training, hunting, or military exceptions in Section 948.60. [8]

Important notice: A voluntary bill of sale does not legalize an otherwise prohibited transfer. [13]

Buying a Firearm

• Wisconsin requires no general purchase permit, owner license, or firearm registration. A federally licensed dealer runs a background check on every sale: handgun sales go through the state's own Section 175.35 process, while long-gun sales go through the federal NICS system directly. [1][12][16]
• The state repealed its 48-hour handgun waiting period in 2015. A dealer may now complete a handgun sale as soon as the Department of Justice returns an approval number, though the DOJ has up to five working days to resolve an unclear result before the dealer may proceed on other grounds. A concealed carry license is not a purchase permit and does not substitute for the dealer background-check process. [12][3]

• Dealer minimums are generally eighteen for rifles and shotguns and twenty-one for handguns and frames or receivers. [14]
• Private transfers remain subject to Wisconsin's juvenile-possession and prohibited-recipient rules even without dealer processing. [8][1]

Ownership and Prohibited Persons

• Wisconsin and federal law prohibit firearm possession by people convicted of a felony, people adjudicated delinquent for an act that would be a felony if committed by an adult, people found not guilty of a felony by reason of mental disease or defect, and people subject to a qualifying domestic-abuse, harassment, or child-abuse injunction or a mental-health or domestic-violence firearm restriction order. A violation is generally a Class G felony, with mandatory minimum confinement for repeat violent offenders. [9]
• Restoration of firearm rights after a Wisconsin felony conviction is narrow. Completing a sentence or probation does not by itself restore rights. The statute recognizes only a pardon expressly restoring firearm privileges, federal relief from disability under 18 U.S.C. 925(c), or a court determination that a person adjudicated delinquent or committed for mental-health reasons no longer poses a danger. Wisconsin has no general owner license or extreme-risk protection-order statute. [9]

• Do not assume that completing probation or paying court fees automatically restores firearm rights. [9]
• An active domestic-abuse, harassment, or child-abuse injunction can independently prohibit possession even without a criminal conviction. [9]

Concealed and Open Carry

• Wisconsin generally requires a concealed carry license to carry a concealed weapon in public. The main exceptions are a person's own dwelling, place of business, or land they own, lease, or legally occupy, plus active peace officers and certain qualified current or former out-of-state officers. The Department of Justice issues five-year licenses to qualifying applicants age twenty-one or older who submit fingerprints, pass a background check, and provide proof of approved firearms training; no new training certificate is required at renewal. [2][3][4]
• Wisconsin also recognizes a valid license issued by another state under rules published by the Department of Justice, so a nonresident who holds a qualifying out-of-state license may carry concealed while in Wisconsin. Open carry of a visible firearm does not require a license for an adult who may lawfully possess it, but the same restricted-location, disorderly-conduct, and private-property rules that limit concealed carry can still apply, and a person under eighteen may not possess a firearm outside the supervised-training, hunting, or military exceptions. [3][2][8]

• A license applicant must complete Department of Justice-approved training; the license itself is valid for five years and may be renewed without a new training certificate. [3][4]
• Carrying openly does not by itself violate Section 941.23, but it does not exempt the carrier from restricted-location or trespass rules that apply regardless of license status. [2]

Self-Defense and the Castle Doctrine in Wisconsin

• Wisconsin Constitution Article I, Section 25 protects "the right to keep and bear arms for security, defense, hunting, recreation or any other lawful purpose." [18]
• Section 939.48(1) generally justifies using force, and in some cases deadly force, when and to the degree a person reasonably believes it is necessary to prevent or terminate an unlawful interference with their person; deadly force is justified only when the person reasonably believes it necessary to prevent imminent death or great bodily harm. [19]
• Section 939.48(1m) adds a castle-doctrine presumption: a court must presume the actor reasonably believed deadly force was necessary if someone unlawfully and forcibly entered, or was in the process of entering, the actor's occupied dwelling, motor vehicle, or place of business, and the actor was present and knew or had reason to know of the unlawful entry. The presumption does not apply if the actor was engaged in criminal activity at the time, or if the person against whom force was used was a public safety worker performing official duties. [19]
• Wisconsin has no general statutory duty to retreat, and the castle-doctrine presumption in subsection (1m) specifically bars a factfinder from weighing whether the actor could have fled before using force in a qualifying dwelling, vehicle, or place-of-business confrontation. Outside that specific presumption, whether retreat was available can still bear on whether the actor's belief was objectively reasonable. [19]
• Deadly force to protect property alone is not justified. Section 939.49 allows reasonable, non-deadly force to prevent or stop an unlawful interference with property, but it is not reasonable to use force intended or likely to cause death or great bodily harm for the sole purpose of defending property. [20]

Important notice: Wisconsin Statute 895.62 grants civil-liability immunity, plus a mandatory award of attorney fees and costs, when the same castle-doctrine conditions are met: unlawful and forcible entry into the actor's dwelling, motor vehicle, or place of business, with the actor present and aware of the entry. That civil-immunity statute is narrower than the criminal-justification statute, Section 939.48 — it covers only the castle-doctrine entry scenario, so a self-defense claim outside a qualifying dwelling, vehicle, or business entry is not automatically immune from a civil lawsuit even if criminally justified. Every self-defense situation is fact-specific and high-stakes. Get individualized legal advice before relying on any of this content in an actual confrontation. [21][19]

Transportation and Vehicles

• A handgun may generally be loaded while in a vehicle in Wisconsin, but carrying it concealed there, such as hidden in a glovebox or under a seat, still counts as carrying a concealed weapon and generally requires a Wisconsin license or a recognized out-of-state license. A long gun in a vehicle must generally be unloaded; Section 167.31 prohibits loading any firearm other than a handgun while in a vehicle and prohibits discharging a firearm from one. [2][6][3]
• Federal safe-passage protection under 18 U.S.C. 926A can cover a person transporting a firearm through Wisconsin between two states where possession is lawful, provided the firearm is unloaded and inaccessible from the vehicle's passenger compartment, or the vehicle has no compartment separate from the passenger area and the firearm is in a locked container. Hunters and target shooters transporting long guns should also confirm current Chapter 29 hunting-transport rules, which are separate from Section 167.31. [17][6]

• An unlicensed adult may keep a loaded handgun in a vehicle only if it is not concealed from view. [2][6]
• For federal interstate safe passage, keep the firearm unloaded and inaccessible, or in a locked container if the vehicle has no separate trunk compartment. [17]

Restricted Firearms and Magazines

• Wisconsin has no general magazine-capacity limit or assault-weapon ban. Suppressors and short-barreled rifles or shotguns are generally lawful to possess once the required federal National Firearms Act registration, tax, and transfer steps are complete; Section 941.298 exempts a person who has complied with the federal silencer registration requirements from the state silencer offense. [1][5][11][15]
• Machine guns are treated more strictly. Section 941.26 makes unlicensed possession, transport, or modification of a firearm into a machine gun a felony, and converting a semiautomatic firearm to fire automatically is a separate, more serious felony. The statute exempts law enforcement and military personnel acting in their official duties, licensed federal firearms curio-and-relic or manufacturer or dealer license holders, and anyone who has completed the federal National Firearms Act licensing and registration process for that weapon. [10][15]

• A federal tax stamp does not excuse unlawful use, prohibited-person possession, or carry in a restricted location. [10][15]
• Confirm current federal manufacture and transfer dates before assuming a particular machine gun may be lawfully transferred, since Wisconsin's exceptions track federal NFA compliance rather than creating independent state registration. [10][15]

Safe Storage and Reporting

• Wisconsin has no universal firearm-locking law and no general statewide deadline for an ordinary owner to report a lost or stolen firearm. Section 948.55 instead creates conditional liability: a person who leaves a loaded firearm within reach of a child under fourteen faces a forfeiture, and the offense becomes a misdemeanor or felony if the child obtains the firearm and possesses it in public, displays it in a threatening manner, or causes death or injury. [7]
• Section 948.55 provides defenses, including that the child gained access through unlawful entry, that the firearm was secured with a locking device or in a locked container, or that the person reasonably believed no child was likely to be present. The absence of a universal storage mandate does not eliminate liability under separate unlawful-transfer or negligence rules, and a prompt voluntary theft report can help place a stolen serial number in law-enforcement systems. [7]

• Use a locked safe, cable lock, or other locking device when a child under fourteen may have access to the home. [7]
• Keep photographs, serial numbers, and purchase records separate from the firearm to speed up a theft report. [7]

Restricted Locations and Private Property

• Section 175.60(16) lists locations where even a valid concealed carry license does not authorize carry: police stations, sheriff's offices, and state patrol stations; jails, prisons, and secured correctional facilities; secure mental-health facilities for sexually violent persons; any courtroom; and any part of a building owned, occupied, or controlled by the state or a local government, as well as university and college buildings, except in each case for any leased residential or business premises within that building. [3]
• A private or public building owner may separately post notice excluding firearms from the premises, and refusing to leave after being asked can lead to trespass consequences. Federal buildings, federal courthouses, and K-12 school grounds carry their own restrictions under federal law and Wisconsin's school-safety statutes regardless of license status. [3][2]

• A license does not override the Section 175.60(16) location list; carrying into a listed location is a separate offense even for a licensee. [3]
• Check current Department of Justice guidance on required sign wording and placement before relying on posted notice at a private business. [4]

State Preemption and Local Rules

• Section 66.0409 broadly bars a city, village, town, or county from enacting or enforcing an ordinance that regulates the sale, purchase, transfer, ownership, possession, bearing, transportation, licensing, permitting, registration, or taxation of a firearm, ammunition, or reloading component, unless the local rule matches state law. [5]
• The statute preserves a handful of local powers: a city or village with village powers may still restrict discharge of a firearm, subject to a self-defense exception, and may prohibit weapons inside buildings the municipality owns, occupies, or controls; counties retain authority over sales or use taxes; and municipalities may use zoning to regulate the construction or expansion of shooting ranges. Certain ordinances enacted before November 1995 that substantially mirror state law can also remain enforceable. [5]

• Check state statutes and Department of Justice guidance first rather than assuming a city may create its own purchase, registration, storage, or carry system. [5]
• A municipal building may still lawfully exclude firearms even though the city generally cannot regulate firearm ownership or carry elsewhere. [5][3]

Before Completing a Private Firearm Sale in Wisconsin

• Confirm Wisconsin residency, identity, age, and eligibility before a private transfer. [1][13]
• Use a licensed dealer for interstate transfers or whenever eligibility is uncertain. [13]
• Get a Wisconsin concealed carry license, or confirm a recognized out-of-state license, before carrying a concealed weapon. [2][3]
• Check the Section 175.60(16) location list and any posted private-property notice before carrying into a building. [3]
• Keep long guns unloaded in a vehicle and confirm any handgun is not concealed unless you hold a qualifying license. [6][2]
• Store firearms securely with a locking device when a child under fourteen may have access. [7]
