Understanding ATF Form 4473
ATF Form 4473, the firearms transaction record, is the cornerstone document for every firearm transferee to a nonlicensee conducted by a federal firearms licensee. This form serves as the primary record for background checks and compliance with federal firearms laws under the Gun Control Act.
The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) requires strict adherence to ATF Form 4473 procedures. Each section must be completed accurately by both the buyer/transferee and FFL to prevent violations that could result in criminal charges, civil penalties, or license revocation.
Why Accurate Completion is Critical
Form 4473 serves multiple critical functions for public safety and law enforcement:
- Background Check Documentation: Records buyer’s consent for FFL to conduct a background check, NICS/background check agency contact date, and response as required for each firearms transaction
- Prohibited Person Screening: Identifies individuals who cannot legally purchase firearms under federal law
- Straw Purchase Prevention: Contains specific questions designed to detect and prevent illegal straw purchases
- Criminal Investigation Support: Provides law enforcement with firearm tracing information when needed
- Captures All Transaction Information: Records the buyer’s details, including address of residency, seller information, including address, FFL number, and person completing the transaction, and all firearm information, including serial number, type, model, caliber/gauge
- Affidavit of Ability to Transact: Documents all information for buyer, including consent for background check, validation not prohibited from firearm transaction, and seller’s certification of all necessary compliance and eligibility.
- FFL Compliance Verification: Demonstrates proper adherence to federal firearms regulations during ATF inspections
Any false statement on Form 4473 can result in up to 5 years imprisonment (18 U.S.C. §924(a)(1)(A) and $250,000 in fines. Since August 2022, FFLs must retain all Forms 4473 permanently (whether or not a transfer occurred), including transferring all Forms 4473, properly filed to the ATF Out of Business Records Center upon discontinuance of operations of that FFL. All Forms 4473 must be readily available for ATF inspection, filed per regulations, on FFL premises.
2023 ATF Form 4473 Changes
Due to new statutory requirements from the NICS Denial Notification Act and Bipartisan Safer Community Act, plus ATF Final Rule 2021R-05F implementation, ATF implemented significant Form 4473 revisions. The first revision was December 2022 with mandatory use starting April 2023, followed by the August 2023 version becoming mandatory February 1, 2024.
Section A Updates
Added “Privately Made Firearms (PMF)” requirements to Question 1, including PMF serial number marking requirements. Gun dealers must now record any privately made firearm received by the FFL with specific marking protocols. Also added city limits checkbox per BSCA requirements for enhanced residence verification.
Section B Enhancements
Question 10 now asks if transferees reside within city limits of their listed address. New questions specifically target straw purchasers with expanded questions on trafficking and enhanced actual buyer verification (Question 21a). These changes strengthen prohibited person screening throughout the firearms transaction process.
Section C Modifications
Updated NICS contact documentation requirements and enhanced transaction number tracking. Gun stores must maintain more detailed background check records to support law enforcement investigations and ATF compliance verification.
Enhanced Penalties
Strengthened language regarding false statements and straw purchases, with clearer warnings about criminal charges for violations of federal firearms laws.
Potential 2025 Form 4473 Changes
In May 2025, ATF launched its New Era of Reform initiative, aimed at simplifying Form 4473 and enhancing e-forms to make it more user-friendly for both purchasers and federal firearms licensees.
Confirmed ATF Reform Initiatives
- Form Simplification: ATF is working to make Form 4473 shorter and more concise
- Error Reduction Focus: Streamlining to reduce unintentional paperwork errors that have led to FFL violations
- User-Friendly Design: Improving clarity and reducing confusion for gun buyers and dealers
- Electronic Integration: Enhanced ATF eForm 4473 capabilities and electronic signature support
Proposed DOGE Efficiency Changes
Draft Proposal Only (Under Review – Not Yet Final): DOGE staff are reportedly planning to reduce Form 4473 from seven pages to three pages, consolidating multiple eligibility questions about mental health, military discharge, and drug use into simplified prompts while maintaining felony conviction questions separately. Nothing has been implemented yet.
Status: These proposals remain under review as of July 2025 and have not been formally implemented.
Legislative Inquiries
In April 2025, Rep. Clay Higgins requested ATF updates to Form 4473 to clarify rights-restoration and pardon provisions. However, these suggestions remain under consideration with no formal amendments implemented.
All proposed changes are still under review. FFLs must continue using the current August 2023 version of Form 4473 until ATF officially announces new requirements. FFLGuard will notify all clients immediately when changes are finalized.
Avoiding Common Form 4473 Mistakes
Based on ATF’s 2024 inspection data, Form 4473 errors contribute the majority of FFL license violations. These are the most frequently cited violations that put federal firearms licenses at risk:
1. Incomplete Transferee Information (Section A)
Gun buyers must properly complete all required personal information fields. Missing data on name, address, date of birth, or identification can invalidate the firearms transaction record and create compliance issues.
2. Missing NICS Contact Documentation (Section C)
FFLs must record the exact date NICS/background check agency was contacted for the background check as well as the associated transaction number. This federal requirement ensures proper tracking of each firearm transaction and supports law enforcement investigations.
3. Unsigned or Undated Forms
Both the gun transferor and transferee must sign and date Form 4473. Missing signatures in Section B and/or Section D or Section E could invalidate the transfer and create serious ATF violations during inspections.
4. Inadequate Identification Verification
FFLs must obtain and document proper buyer identification. Failure to verify and document identity can result in sales to prohibited persons and expose gun stores to criminal liability.
5. Incorrect Firearm Information
Serial numbers, manufacturer, model, and caliber/gauge must be recorded accurately. Errors in firearm identification compromise law enforcement tracing and violate federal firearms regulations.
6. Straw Purchase Warning Failures
With enhanced questions targeting straw purchasers, FFLs must be vigilant in identifying suspicious transactions where someone may be buying firearms for another person.

FAQs
When NICS returns a “denied” response, the federal firearms licensee cannot transfer the firearm to the prohibited person and must retain the completed ATF Form 4473, filed per all regulatory requirements. The FFL should document the denial as required on ATF Form 4473.
FFLs should have appropriate training for their employees and be ever-vigilant in watching for straw purchase indicators, such as someone other than the apparent actual buyer completing forms, gun buyers showing unfamiliarity with the firearm, or unusual payment arrangements. Federal firearms licensees should refuse transactions where they suspect a straw purchase, as this violates federal firearms laws.
Gun buyers struggle with questions involving criminal history, substance use, and mental health determinations. Common confusion areas include Question 21f about unlawful user status of controlled substances and Question 21h about mental health adjudications – buyers mistakenly think voluntary counseling disqualifies them when it refers to court determinations of mental defectiveness or involuntary commitment. Remember, as an FFL you may not assist a buyer/transferee in completing ATF Form 4473 in any way. If a person completing ATF Form 4473 has questions, refer him/her to the instructions on the Form. If he/she cannot answer after reading all available information on ATF Form 4473, the FFL should direct customers to seek legal counsel rather than provide interpretive guidance.
