Free Arizona Gun / Firearm Bill of Sale
Arizona has been a constitutional-carry state since 2010 and treats lawful firearms transactions between residents as a private matter. There is no state firearm registry, no permit-to-purchase, no waiting period, and no state-mandated background check on private-party sales between Arizona adults who may legally own guns. A bill of sale is still strongly recommended as the buyer's and seller's record of the transaction — make, model, serial number, caliber, date, and signed acknowledgment that both parties believe the other is a lawful possessor. Federal law overlays the basics: machine guns still need ATF approval (suppressors and short-barreled rifles no longer do as of October 9, 2026), and sales to out-of-state residents must go through a Federal Firearms License (FFL) holder. Arizona law (A.R.S. § 13-3101) still bans suppressors, short-barreled rifles and shotguns, and machine guns unless they are possessed or transferred in compliance with federal law, and it is not settled whether an item ATF no longer registers meets that test, so ask an Arizona firearms attorney before you buy or sell one without a Form 4.

Arizona Gun / Firearm Bill of Sale — What You Need to Know
Sales Tax Details
No private-party sales tax on firearms in Arizona. Dealer (FFL) sales include the 5.6% state TPT plus city/county add-ons (effective 7-9.5%).
Exemption: Private-party transfers between Arizona residents are not subject to TPT. Family transfers and gifts are also untaxed.
Inspection Requirements
Arizona is a constitutional-carry state — no permit, no registration, no waiting period, and no state-mandated background check for private-party transfers between two Arizona residents who lawfully may possess firearms. Federal law still applies: machine guns require an approved ATF Form 4 and the $200 tax (since October 9, 2026 ATF no longer requires approval for suppressors and short-barreled rifles); sales to residents of other states must go through an FFL.
Registration
Registration for this vehicle type is handled by No state firearm registry in Arizona — not the same agency that handles cars in Arizona. Plan for separate filings.
Arizona Gun / Firearm Sale — Step-by-Step Checklist
- Record make, model, caliber, type (handgun/long gun), serial number, sale price, and date
- Both parties affirm Arizona residency and that neither is a federally prohibited person
- For inter-state transfers, ship to an FFL in the buyer's state and complete ATF Form 4473 there
- For a machine gun, file ATF Form 4, pay the $200 tax and wait for approval before transfer; since October 9, 2026 ATF no longer requires approval or registration for suppressors and SBRs (a Form 4 can still be filed voluntarily), but Arizona law (A.R.S. § 13-3101) only allows these items in compliance with federal law, so check with an Arizona firearms attorney first
- Optional: voluntary FFL background check on a private-party sale for extra peace of mind
- Each party keeps a signed copy — Arizona has no state filing requirement
- Verify any local city or HOA restrictions if relevant
Common Pitfalls
- Selling to someone you have reason to believe is a prohibited person — federal felony regardless of state law
- Shipping a firearm directly across state lines instead of through an FFL
- Transferring a machine gun without filing ATF Form 4 and waiting for approval
- Confusing constitutional carry with no rules — federal prohibitions still apply
- Forgetting to record the serial number, leaving no proof if the firearm is later recovered
- Assuming a CCW permit is needed — Arizona requires no permit for adults 21+ to carry concealed
Pro Tip
Arizona's firearms law is among the most permissive in the country — and the bill of sale is your private record. Capture serial number, confirm legal possession, and follow federal rules on inter-state and NFA transfers.
