Idaho Gun Laws: Carry, Permits, and Penalties

Idaho gun laws let any U.S. citizen 18 or older carry a concealed handgun without a permit, and the state imposes no purchase permits, waiting periods, or firearm registration. Federal and state law still decide who can possess a firearm at all, where you can take it, and what a violation costs you.

Who Can Legally Own a Firearm

Idaho does not require a license to buy a gun. The floor comes from federal law: 18 to buy a rifle or shotgun from a licensed dealer, 21 for a handgun.¹ Idaho adds no separate purchase-age rule, though minors under 18 generally need a parent or guardian’s consent to possess a firearm.

Federal law under 18 U.S.C. § 922(g) bars several categories of people from possessing any firearm or ammunition: anyone convicted of a crime punishable by more than a year in prison, fugitives, unlawful users of controlled substances, people adjudicated as mentally defective or committed to a mental institution, anyone dishonorably discharged, people subject to qualifying domestic violence restraining orders, and anyone convicted of a misdemeanor crime of domestic violence.¹

Idaho reinforces this at the state level. Idaho Code § 18-3316 makes it a separate felony for anyone previously convicted of a felony to possess a firearm, punishable by up to five years in prison, a fine up to $5,000, or both.²

Restoring Firearm Rights After a Felony

Idaho Code § 18-310 suspends civil rights on a felony conviction, including the right to possess firearms. You can apply for restoration through the Idaho Commission of Pardons and Parole once you have waited at least five years after completing all felony sentences, paid every court-ordered fine, fee, and restitution amount in full, and are no longer incarcerated or under supervision for any conviction. Denied applicants can reapply once every 12 months.³ For certain offenses listed in the statute, restoration is available only through the commission or by pardon, which itself automatically restores firearm rights when granted.

Carrying Concealed Without a Permit

Idaho is a constitutional carry state. Under Idaho Code § 18-3302, you may carry a concealed handgun with no license as long as you are at least 18, a U.S. citizen or current member of the Armed Forces, and not otherwise disqualified from possessing a firearm.⁴ The legislature expanded this in 2020 from Idaho residents only to any U.S. citizen, so eligible visitors from other states can carry concealed here too.

The disqualifiers track the federal prohibited-persons list and add a few more: anyone currently charged with a crime punishable by more than a year of imprisonment, anyone on probation for a qualifying offense who has not completed it, and anyone free on bond pending trial for a disqualifying crime.⁵

Even people who fall outside the permitless carry rules keep some options. You can carry concealed on your own property, on any property where you have an ownership or leasehold interest, and on private property where the owner or tenant gives you permission. Unloaded firearms secured in a case and firearms in a motor vehicle are exempt from licensing requirements regardless of age or citizenship.⁵

The Enhanced Concealed Weapons License

You do not need a license to carry in Idaho, but the state issues an enhanced concealed weapons license under Idaho Code § 18-3302K for people who want their permit recognized in other states. Many states that decline to honor Idaho’s permitless carry will still honor the enhanced license because of its training requirement.

Qualifying for the enhanced license means meeting several conditions. You must be at least 21 and either an Idaho resident for at least six consecutive months before applying or the holder of a current concealed carry license from your home state. You have to complete an eight-hour, in-person handgun course within the 12 months before applying that covers Idaho firearms law, safe handling, self-defense principles, and live-fire training with at least 98 rounds fired. Fingerprints go through a national background check, and you cannot be disqualified under any state or federal prohibition.

The base fee is $20, though your county sheriff may charge additional amounts for fingerprint processing and materials, so total costs vary by county.⁶ The sheriff has 90 days from your filing date to issue the license, which is valid for five years. The training must be taught face-to-face by an instructor certified through the NRA, another nationally recognized organization, or the Idaho Peace Officers Standards and Training Council. Online courses do not qualify.

Reciprocity and Out-of-State Visitors

Idaho’s reciprocity agreements are managed by the Idaho State Police Bureau of Criminal Identification. Some states honor only Idaho’s enhanced license, not the basic one, so check the ISP reciprocity page before traveling.⁶ Even where reciprocity applies, the carry laws of the state you are in control your conduct there.

Visitors with a valid concealed carry permit from another state can carry in Idaho without an Idaho license, but the out-of-state permit must be in your physical possession.⁵ Because permitless carry now extends to all U.S. citizens who meet the eligibility rules, most visitors will not need a permit at all.

Where You Cannot Carry

Constitutional carry does not override location-based restrictions in state or federal law.

Courthouses, Jails, and Schools

Idaho Code § 18-3302C prohibits concealed weapons in a courthouse, juvenile detention facility, jail, or public or private school. Exceptions cover peace officers on duty, security personnel, and anyone specifically authorized by the person or entity controlling the building.⁷

Idaho Code § 18-3302D separately makes it a misdemeanor to possess a firearm or dangerous weapon on school property, in buildings being used for school activities, or on school-provided transportation. The rule applies to public and private elementary and secondary schools. Adults over 18 who are not enrolled students can keep a firearm locked and secured in their vehicle on school grounds, and anyone acting in lawful self-defense under Idaho Code § 19-202A is also exempt.⁸

Federal Facilities

Federal law prohibits firearms in any federal facility, meaning a building or portion of a building owned or leased by the federal government where federal employees regularly work. Post offices, federal courthouses, Social Security offices, and VA buildings all qualify. A first offense carries up to one year in prison. Bringing a firearm into a federal court facility carries up to two years, and possessing one with intent to use it during a crime in a federal building carries up to five.⁹

Private Property

Idaho preserves the right of private property owners, tenants, employers, and businesses to prohibit firearms on their premises.⁵ Idaho does not assign a specific criminal penalty for ignoring a private “no weapons” sign the way some states do, but refusing to leave after being asked can lead to trespassing charges.

Buying and Transferring Firearms

There is no waiting period in Idaho. A licensed dealer must run every purchaser through the FBI’s National Instant Criminal Background Check System before completing the transfer.¹⁰ NICS screens for disqualifying factors like felony convictions, domestic violence records, and active restraining orders. If the FBI cannot complete the check within three business days, the dealer may proceed under federal law.¹

Private sales between individuals do not require a background check under federal or Idaho law. Federal law mandates checks only for sales through licensed dealers and does not regulate private transactions between residents of the same state.¹ Selling a firearm to someone you know or have reason to believe is prohibited from possessing one is still a crime, and under Idaho law knowingly transferring a firearm to a prohibited person is a felony.

Straw purchases are a separate federal felony. Buying a firearm on behalf of someone prohibited from owning one, or someone who intends to use it in a crime, carries up to 15 years in federal prison. If the firearm is intended for use in a felony, terrorism, or drug trafficking, the penalty rises to 25 years.¹¹

Self-Defense and Stand Your Ground

Idaho Code § 19-202A gives Idaho one of the country’s broader self-defense protections. The statute states that no person “shall be placed in legal jeopardy of any kind whatsoever” for protecting themselves or their family by reasonable means, or for coming to the aid of someone they reasonably believe is the victim of aggravated assault, robbery, rape, murder, or another serious crime listed in the statute.¹²

The phrase “legal jeopardy of any kind whatsoever” is broad enough to cover both criminal prosecution and civil lawsuits, so a lawful self-defense shooting shields you from being sued by the person you shot as long as the force used was reasonable.

Idaho imposes no duty to retreat. You are not required to flee or attempt escape before using force in self-defense, whether you are at home, in your car, or in public. In any prosecution for unlawful use of force, the state carries the burden of proving the force was not justified.¹² The main limitation: you cannot claim self-defense if you were engaged in illegal activity at the time. Starting a fight and then pulling a gun when it goes badly does not qualify.

Penalties for Firearm Violations

Penalties in Idaho scale with the conduct.

Carrying concealed in violation of § 18-3302 is a misdemeanor. This applies to people who do not meet the age, citizenship, or eligibility rules for permitless carry and carry concealed anyway.⁵
Possessing a firearm on school property is a misdemeanor under § 18-3302D, subject to the vehicle-storage and self-defense exceptions.⁸
Felon in possession under § 18-3316 is a felony carrying up to five years in state prison, a fine up to $5,000, or both.²
A firearm in a federal facility carries up to one year for a standard violation, up to two years for a federal court facility, and up to five years if the firearm was intended for use in a crime.⁹

Sentence Enhancement for Using a Firearm in a Crime

Idaho Code § 19-2520 adds up to 15 years to the sentence of anyone who displays, uses, or threatens to use a firearm while committing certain listed felonies. It is not a blanket enhancement. The statute lists specific offenses including aggravated assault, aggravated battery, burglary, murder, manslaughter, kidnapping, rape, robbery, and drug trafficking. The enhancement increases the maximum authorized sentence by 15 years, stacking on top of whatever the underlying crime already carries.¹³

Local Preemption and Firearm Storage

Idaho Code § 18-3302J prevents counties, cities, and other political subdivisions from adopting any law regulating the sale, possession, transfer, ownership, transportation, carrying, or storage of firearms. Only the state legislature can pass firearms regulations, which keeps the rules the same whether you are in Boise, Coeur d’Alene, or a rural county.¹⁴

Idaho has no state law mandating specific firearm storage practices. There are no requirements for gun safes, trigger locks, or locked cabinets. Negligent storage that leads to harm can still create civil liability, so the absence of a criminal storage rule is not the absence of legal risk.

A Note on Suppressors and NFA Items

The Idaho Firearms Freedom Act, Idaho Code § 18-3315A, declares that firearms and accessories manufactured and kept within Idaho are not subject to federal regulation under the Commerce Clause, and it specifically lists sound suppressors among the covered accessories. The statute excludes fully automatic firearms.¹⁵ Federal courts have consistently held that state firearms freedom acts do not override federal law, so items regulated under the National Firearms Act, including suppressors, short-barreled rifles, and short-barreled shotguns, still require federal registration through the ATF. Relying on the state statute alone to skip NFA compliance is legally risky.
