Free Maine Gun / Firearm Bill of Sale
Maine is one of the most permissive states in the Northeast for firearms transactions. There is no permit-to-purchase, no state firearm registry, constitutional carry for handguns since 2015, and — critically — no universal background check requirement on private sales (Maine voters rejected Question 3 in 2016). Private party-to-party transfers between Maine residents who are both legally allowed to possess firearms are lawful without a dealer or background check. A bill of sale is not legally required, but it protects both parties: it documents the date, parties, and serial number, which matters if the firearm is later misused, lost, or stolen. Federal rules still apply to dealer sales, NFA items, and interstate transfers.

Maine Gun / Firearm Bill of Sale — What You Need to Know
Sales Tax Details
Maine 5.5% sales tax applies to retail firearm purchases through dealers. Private casual sales between Maine residents are not subject to sales tax collection by the seller, though use tax technically applies to the buyer.
Inspection Requirements
No firearm inspection or registration in Maine. Federal law still applies: licensed dealer transfers require Form 4473 and NICS background check.
Maine Gun / Firearm Sale — Step-by-Step Checklist
- Verify both parties are Maine residents and legally allowed to possess firearms (not prohibited persons under 18 USC 922(g))
- Write a bill of sale: buyer/seller full names and addresses, date of birth, driver's license numbers, firearm make/model/caliber/serial number, sale price, and date
- Both parties retain a signed copy permanently (no state filing required)
- For interstate transfers, federal law requires the firearm to ship to a licensed FFL dealer in the buyer's state for Form 4473 and NICS check
- For NFA items (suppressors, short-barrel rifles, machine guns), use ATF Form 4 with $200 tax stamp and CLEO notification — months-long wait
- Optional but recommended: voluntary NICS check via a licensed FFL ($25-$50) before private transfer to confirm buyer is not prohibited
- If selling to someone you do not personally know, ask for a state ID and document it on the bill of sale
Common Pitfalls
- Selling to someone you have reason to believe is a prohibited person (felon, domestic abuser, addict) — federal felony exposing seller to up to 10 years in prison even without a state background check requirement
- Failing to use an FFL for an out-of-state buyer — federal felony under 18 USC 922(a)(5), regardless of how casual the sale seems
- Transferring an NFA item without a tax stamp — 10 years federal prison and forfeiture; a $200 stamp and 6-12 month wait is the only legal path
- No bill of sale, then the firearm is later used in a crime — without documentation of the transfer, the original purchaser of record (you) faces investigative scrutiny
- Assuming Maine's permissive law overrides federal law — it does not; federal age limits, prohibited-person rules, and NFA rules apply in full
Pro Tip
Maine's permissive system puts responsibility on the seller. A two-page bill of sale and a quick ID check protect you legally and morally — there is no excuse to skip them.
