Idaho Gun Laws

• Constitutional Carry Stalwart: Idaho is a robust permitless carry state. Any law-abiding citizen or legal resident of the United States who is 18 years of age or older may carry a concealed or open firearm statewide without a permit. The political climate remains fiercely protective of the Second Amendment.
• Enhanced Permit System: While permitless carry applies universally, Idaho retains a highly popular "Enhanced Concealed Weapons License" (Enhanced CWL), which is specifically required to carry a concealed weapon on public college and university campuses within the state and offers vast out-of-state reciprocity.
• Anti-Federal Overreach: In 2026, Idaho continues to strictly enforce laws prohibiting state and local law enforcement agencies from cooperating with the federal government to enforce any new federal gun control measures or asset seizures that contradict the state constitution.

Idaho is a "Shall Issue" state offering both a Standard Concealed Weapons License (CWL) and an Enhanced CWL, issued by the local County Sheriff.

• Minimum Age: 18 years old for a Standard CWL; 21 years old for an Enhanced CWL (or 18 if active-duty military). Note: Permitless carry applies at 18.
• Training Requirements: A Standard CWL generally requires basic familiarity (often satisfied by a hunter's ed course or basic pistol class). The Enhanced CWL mandates an extensive 8-hour course taught by a certified instructor, including legal instruction and a minimum of 98 rounds fired in a live-fire qualification.
• Background Checks: A state (Idaho State Police) and federal (FBI NICS) background check is mandatory.
• Fingerprints: A complete set of fingerprints is required at the sheriff's office.
• Application Fees: Initial fees are approximately $38.50 to $40.00 for a Standard CWL, and around $60.00 for the Enhanced CWL, plus fingerprint and background check fees which can bring the total closer to $100 depending on the county.
• Processing Times: By law, the Sheriff must issue or deny the license within 90 days of receiving a completed application.

Idaho maintains no state-level restrictions on firearms or magazines, fully embracing federal baselines.

• Magazine Capacity: No restrictions. Any capacity magazine is legal to possess, sell, and carry.
• "Assault Weapon" Bans: None. Idaho has no laws regulating or banning semi-automatic firearms based on features or appearance.
• Restricted Ammunition: No state-specific bans. Idaho defers to federal law regarding armor-piercing handgun ammunition.
• Banned Models: No specific firearm models or makes are banned by name in Idaho.

Idaho fortified its self-defense laws in 2018, providing some of the clearest protections in the Pacific Northwest for justified shooters.

• Stand Your Ground: Yes. Idaho law explicitly states that a person has no duty to retreat before using deadly force if they are in a place they have a legal right to be.
• Castle Doctrine: Yes. The law applies a legal presumption that anyone unlawfully and forcefully entering an occupied home, business, or vehicle intends to commit a felony, justifying the use of deadly force.
• Duty to Retreat: No. There is no legal requirement to retreat from a threat in Idaho.
• Civil Immunity: Yes. If a court finds the use of force was justified under criminal law, the defender is statutorily immune from civil lawsuits brought by the attacker or their estate.

Idaho’s transportation laws perfectly align with its permitless carry philosophy.

• Handguns: Any law-abiding individual 18 or older may transport a loaded, concealed handgun anywhere inside the passenger compartment of a vehicle without a permit.
• Long Guns: May be transported in a vehicle. While state law does not require them to be unloaded, it is strongly recommended for safety and to comply with local hunting/poaching regulations in wildlife areas.
• Federal Gun-Free School Zone Act: Constitutional carry does not satisfy the federal exemption. To legally drive within 1,000 feet of a K-12 school without running afoul of federal law, an Idaho-issued CWL or Enhanced CWL is required.

Idaho relies on the federal NICS system for commercial sales and does not regulate private sales.

• Dealer Sales: All sales through an FFL require a standard NICS background check.
• Private Sales: No background check or registration is required for private firearm transfers between Idaho residents.
• Waiting Periods: There are no mandatory waiting periods for firearm purchases in Idaho.
• CCW Bypass: A valid Idaho Standard CWL or Enhanced CWL acts as an exemption to the NICS background check at an FFL, allowing for immediate transfer.

Idaho does not have an Extreme Risk Protection Order (Red Flag) law. In fact, the state legislature has routinely introduced and passed measures actively preventing the implementation of Red Flag laws or the use of state funds to enforce them, ensuring firearms cannot be seized without full criminal due process.

Because Idaho is a constitutional carry state, there is no penalty for carrying a concealed weapon without a permit as long as the carrier is 18+, a U.S. citizen or legal resident, and not a prohibited possessor. However, carrying a concealed firearm into a statutorily prohibited location (like a courthouse or a veterans home) is generally charged as a misdemeanor, punishable by up to 6 months in jail and a fine of up to $1,000.

Carrying a firearm onto K-12 school grounds without express permission from the school board is a much more severe offense. Additionally, while carrying in a bar is not statutorily illegal, carrying a concealed weapon while intoxicated by alcohol or drugs is a misdemeanor. If a prohibited person (such as a convicted felon) is caught in possession of a firearm, it is a felony carrying a sentence of up to 5 years in state prison and a $5,000 fine.
