Free Iowa Gun / Firearm Bill of Sale
Iowa is a permissive firearms state. The Iowa permit-to-acquire (PTA) for handguns was eliminated in July 2021, and Iowa is now a constitutional carry state — no permit needed to purchase, possess, or carry a handgun for most adults 21+. There is no Iowa permit-to-purchase requirement for long guns either. Private gun sales between Iowa residents are legal without a background check at the state level, though federal law still prohibits transferring to a known prohibited person. A bill of sale is NOT legally required for a private firearm transfer in Iowa, but it is strongly recommended — it documents the chain of custody if the firearm is later used in a crime, lost, or stolen.

Iowa Gun / Firearm Bill of Sale — What You Need to Know
Sales Tax Details
Casual private firearm sales between Iowa residents are not subject to Iowa sales tax. Dealer sales (FFL) charge 6% state sales tax plus up to 1% local option.
Exemption: Casual sales between Iowa residents (non-dealer) are exempt from sales tax. Inheritance and gifts also exempt.
Inspection Requirements
No state inspection of firearms. No serial number verification by the state. Federal law (GCA) prohibits removed/altered serial numbers regardless of state law.
Registration
Registration for this vehicle type is handled by None — Iowa does not register firearms — not the same agency that handles cars in Iowa. Plan for separate filings.
Iowa Gun / Firearm Sale — Step-by-Step Checklist
- Verify the buyer is an Iowa resident, 18+ for long guns, 21+ for handguns (federal minimum)
- Bill of sale lists make, model, caliber, serial number, condition, sale price, date
- Both parties sign and date — keep one copy each, indefinitely
- Seller asks buyer to confirm they are not federally prohibited (felon, domestic violence, drug user, etc.)
- Consider a voluntary FFL background check ($25-$50) — protects the seller if buyer turns out to be prohibited
- Photocopy both parties' Iowa driver's licenses and attach to bill of sale
- For interstate sales: must go through an FFL in the buyer's state per federal law
- Store securely — Iowa has no firearm storage law but liability follows the gun
Common Pitfalls
- Selling to someone who turns out to be a prohibited person can expose the seller to federal charges (knowingly transferring) — $250,000 fine, 10 years
- Skipping the bill of sale leaves the seller as last registered owner if the gun is recovered at a crime scene — hours of police interviews
- Shipping a handgun across state lines directly to a buyer (not through an FFL) is a federal felony — 5 years
- Transferring to an out-of-state resident without using an FFL violates federal law regardless of Iowa rules
- Failing to note the serial number on the bill of sale makes it useless for identifying the firearm if stolen
Pro Tip
Iowa is permissive on guns — no permits, no registration. But a signed bill of sale with serial number is your best protection.
