Wisconsin Gun Bill of Sale - Wis. Stat. § 941.29 Private Transfer

There are no background checks for Wisconsin gun sales from private sellers. They're only mandated for FFLs. Private sales between Wisconsin residents require no background check, no FFL dealer, no waiting period, and no state paperwork. However, under Wis. Stat. § 941.29, knowingly selling to a prohibited person is a serious criminal offense. The Bill of Sale records the buyer's self-certification of eligibility as your good-faith defense.

SB 1046 was introduced February 24, 2026 and relates to permits for firearms dealers, firearms transactions and safety. It would repeal and recreate Wis. Stat. § 175.35 and § 175.37. If enacted, the bill would require permits for gun dealers, regulate ghost gun parts, mandate background checks for private sales, and bar purchase of magazines over a certain size. The bill was referred to the Committee on Government Operations — monitor its progress as it could fundamentally change Wisconsin's permissive private sale environment.

Wisconsin requires a Concealed Carry Weapon (CCW) license for concealed carry — no Constitutional Carry as of 2026. The CCW license requires DOJ-approved firearms training and a background check, is shall-issue, and is valid for 5 years. The cost is $40 for new applicants. If your buyer holds a valid CCW license, record the license number on the Bill of Sale — it means they passed a background check and completed firearms training. A CCW license also allows the holder to have a loaded concealed handgun within reach in a vehicle.

Handguns may be left loaded in a vehicle; concealed loaded handguns within reach require a CCW license. Long guns must be unloaded in vehicles, with limited hunting exceptions. Additionally, a Wisconsin court ruled in 2018 that transporting a gun in a glove box without a concealed carry license was illegal. Buyers should understand these rules before driving home from a private sale with their new purchase.

Wisconsin has failed to pass an Extreme Risk law despite significant public pressure. There is no ERPO mechanism in Wisconsin as of 2026. Governor Evers signed an executive order in early 2025 establishing an Office of Violence Prevention to help coordinate gun violence prevention efforts following the Abundant Life Christian School shooting. Wisconsin also has no assault weapons ban and no magazine capacity limits under current law.

The minimum age for private handgun sales in Wisconsin is 18 — three years lower than the federal dealer requirement of 21. For long guns, the minimum age is also 18. Open carry is legal but you must be 18 or older. Wisconsin has no state minimum age for possessing long guns under supervision, but federal law sets the floor at 18 for private purchases. Always verify the buyer's Wisconsin Driver's License or State ID.

Under Wis. Stat. § 948.55, it is a crime to recklessly leave or store a loaded firearm within the reach or easy access of a child under 14 when certain conditions apply. Wisconsin also mandates that dealers must provide written notice regarding child-access penalties at the time of sale. While this applies primarily to dealer sales, private sellers should also inform buyers of this obligation since it applies to how they store the firearm after purchase.

Restaurants that serve alcohol but don't have a bar area allow carry. But sitting at the bar or drinking alcohol while carrying is illegal. Wisconsin's Wis. Stat. § 941.20 specifically prohibits operating or carrying a firearm while under the influence of an intoxicant. This applies to both open and concealed carry. Wisconsin also prohibits carrying in establishments where the primary purpose is the sale of alcohol under Wis. Stat. § 175.60(16)(a).

Wisconsin has state preemption laws which generally forbid cities from passing firearms or knife ordinances stricter than that of state law. The Wisconsin Supreme Court ruled in 2017 that Madison's Metro Transit rule forbidding firearms on public buses violated the state's preemption law. This means gun rules are largely uniform across all Wisconsin counties and cities — though local government buildings can post no-carry restrictions.

No. Federal law under 18 U.S.C. § 922 prohibits private person-to-person firearm transfers across state lines. When a private individual sells a firearm across state lines, a federally licensed firearm dealer must be utilized in the buyer's state of residence to facilitate the transfer. Wisconsin borders Minnesota, Iowa, Illinois, and Michigan — selling directly to a resident of any of them without FFL involvement is a federal felony.
