Free New Mexico Gun / Firearm Bill of Sale
New Mexico moved to universal background checks in 2019 with SB 8: with very few exceptions, every private firearm sale must run through a Federal Firearms License (FFL) holder for a NICS check. A bill of sale by itself is no longer enough. The smart sequence is to draft the bill of sale, meet the buyer at an FFL, complete the NICS, then exchange money and the firearm in front of the dealer. Skipping the FFL is a misdemeanor and exposes both parties to liability.

New Mexico Gun / Firearm Bill of Sale — What You Need to Know
Sales Tax Details
Private party firearm sales between individuals are not subject to NM gross receipts tax. FFL transfer fees ($25–$75 typical) are separate from any tax and are not refundable if the buyer fails the background check.
Inspection Requirements
Universal background check required under NM SB 8 (2019) for nearly all private sales. Narrow exceptions for transfers between immediate family, law enforcement, and certain antique firearms. Don't assume your transfer is exempt — verify with the FFL.
Registration
Registration for this vehicle type is handled by No firearm registry in New Mexico. NICS background check via FFL is required for nearly all private transfers. — not the same agency that handles cars in New Mexico. Plan for separate filings.
New Mexico Gun / Firearm Sale — Step-by-Step Checklist
- Schedule the transfer at a willing FFL holder before exchanging money
- Buyer completes ATF Form 4473 and passes the NICS background check
- Draft a bill of sale capturing make, model, serial number, caliber, sale price, and both IDs
- Pay the FFL transfer fee (separate from sale price; commonly $25–$75)
- Both parties retain signed copies of the bill of sale and the FFL transfer record
Common Pitfalls
- Believing 'private sale' means no background check — NM SB 8 ended that in 2019
- Selling to a buyer who fails NICS and then transferring the gun anyway — felony exposure
- Skipping the serial number on the bill of sale — makes recovery impossible if the gun is stolen later
- Assuming family transfers are always exempt — confirm the relationship qualifies under SB 8 before skipping the FFL
Pro Tip
Since 2019, NM = universal background check. Schedule the FFL, document the serial number, and walk away with paperwork that survives any future trace request.
