Shotgun laws in Iowa

What Iowa adds on top of federal law: short-barreled shotguns, 14-inch "firearms," feature rules, magazine limits, permits and waiting periods.

Federal update — Oct 9, 2026

ATF says it is no longer enforcing federal NFA approval or registration for short-barreled shotguns. That does not change state law: where a state only allows SBSs that are registered under the NFA, you still need that registration to be legal under state law. What changed.

Short-barreled shotgunsLegal with NFA registration

Iowa uses the federal definition of a short-barreled shotgun and makes possession a state crime only when it violates federal law, so a federally registered SBS is allowed.[1]

Iowa Code § 724.1C
14" 'firearms' (Shockwave / TAC-14)Legal

Iowa's only short-shotgun rule makes possession unlawful when it violates federal law, so Iowa adds no restriction beyond federal classification.[1]

Semi-auto / feature rulesNo state feature ban

Giffords lists assault weapon restrictions among the laws Iowa does not have.[2]

Magazine limitsNo limit for shotguns

Giffords lists a large-capacity magazine ban among the laws Iowa does not have.[2]

Permit to buyNo state permit

Long-gun buyers need no permit. The only permit to acquire is an optional one for handguns bought from dealers.[3]

Waiting periodNo waiting period

Iowa has no waiting period for firearm purchases.[4]

Where a state has no official guidance on a point, the summary says what the statute text appears to say, and marks it unclear when it can't be read either way.

Not legal advice

This is a plain-English summary. Cities and counties can add rules, and laws change. Confirm with Iowa's official sources or a licensed attorney before you buy, build or travel.

Federal rules that apply everywhere

  • Under the National Firearms Act, a 'shotgun' is a weapon designed and intended to be fired from the shoulder that uses a fixed shotgun shell to fire shot or a single projectile through a smooth bore with each pull of the trigger. source
  • The Gun Control Act uses nearly the same definition: a shotgun is designed and intended to be fired from the shoulder and fires shot or a single projectile through a smooth bore for each pull of the trigger. source
  • Federal law defines a short-barreled shotgun as a shotgun with a barrel under 18 inches, or any weapon made from a shotgun with an overall length under 26 inches. source
  • The One Big Beautiful Bill Act, the law that cut the NFA tax, is Public Law 119-21 and was approved on July 4, 2025. source
