National Firearms Act wait times are long because application volume has grown roughly 2,400 percent since 2005 while the ATF’s examiner workforce and its legally required manual review process have not scaled with it.1Bureau of Alcohol, Tobacco, Firearms and Explosives. Data and Statistics Right now, the ATF’s posted medians are much shorter than the year-plus horror stories from 2021 and 2022, but the range is wide and moves with demand.
What the Current Wait Actually Looks Like
The ATF publishes median processing times by form type and filing method. As of the most recent posting:
- Form 4 individual, eForms: about 10 days
- Form 4 trust, eForms: about 26 days
- Form 4 paper, individual: about 21 days
- Form 4 paper, trust: about 24 days
- Form 1, eForms: about 36 days
- Form 1, paper: about 20 days
These are medians, not guarantees. Your wait can run shorter or much longer depending on background check complications, errors on the application, and how many other applications are in the pipeline.2Bureau of Alcohol, Tobacco, Firearms and Explosives. Current Processing Times Anyone who bought a suppressor a few years ago remembers waits past a year. The system can swing from weeks to many months when volume spikes.
Why the Backlog Exists
The single biggest driver is volume. The ATF processed about 42,000 NFA forms in fiscal year 2005. By 2013 that had nearly quadrupled to roughly 164,000. In 2023 the division processed more than 1,069,000 forms in a single year.1Bureau of Alcohol, Tobacco, Firearms and Explosives. Data and Statistics Consumer interest in suppressors keeps climbing, and every time Congress debates NFA reform, applications spike as buyers rush to file before rules change.
The review itself is manual by law. The NFA, codified at 26 U.S.C. Chapter 53, requires ATF to approve each transfer individually before the applicant can take possession.3Office of the Law Revision Counsel. 26 US Code Chapter 53 – Machine Guns, Destructive Devices, and Certain Other Firearms An examiner has to verify the applicant, confirm the firearm details, check the background results, and make sure the transfer complies with federal law. Federal law also requires every transfer application to include fingerprints, a photograph, and enough identifying information to verify both the applicant and the firearm.4Office of the Law Revision Counsel. 26 USC 5812 – Transfers Budget constraints limit how quickly the NFA Division can hire, and the specialized work needs significant onboarding before a new examiner is productive.
Trusts Take Longer Than Individual Applications
Many buyers register NFA items through a gun trust rather than as individuals. A trust lets multiple people legally possess and use the items in it, which helps with sharing and inheritance. The tradeoff is more paperwork and a longer wait.
Under the ATF’s Rule 41F, every “responsible person” named in a trust must individually undergo a background check. Each one has to complete ATF Form 5320.23, attach a photograph, submit two sets of fingerprints, and send a copy of the questionnaire to their local chief law enforcement officer.5Bureau of Alcohol, Tobacco, Firearms and Explosives. Background Checks for Responsible Persons (Final Rule 41F) A trust with four responsible persons means four separate background checks, four fingerprint submissions, and four CLEO notifications, all of which have to clear before ATF approves the application.6Bureau of Alcohol, Tobacco, Firearms and Explosives. National Firearms Act (NFA) Responsible Person Questionnaire – ATF Form 5320.23 The CLEO copy is a notification, not a sign-off. Your CLEO does not have to approve the transfer.
The processing times reflect the difference. Form 4 individual eForms currently sit at about 10 days; trust eForms at about 26. If you don’t need the trust structure for shared possession or estate planning, filing as an individual is faster.
Background Check Holds
Every NFA application triggers a check through the FBI’s National Instant Criminal Background Check System. A standard NICS check for an over-the-counter purchase often finishes in minutes; NFA checks can take much longer.7Bureau of Alcohol, Tobacco, Firearms and Explosives. ATF and FBI Formalize Appeals Process for Certain National Firearms Act Applicants When the system returns a “delay” instead of a proceed or a deny, the FBI does a manual review. Common triggers include a name that matches someone in a criminal database, a prior arrest that was dismissed but still appears in records, or missing disposition records from a state court.
Providing your Social Security number on the application is optional, but it helps the FBI tell you apart from other people with similar names, which cuts down on delay flags. If your check returns a delay or denial you believe is wrong, ATF and FBI have a formal appeals process for NFA applicants.7Bureau of Alcohol, Tobacco, Firearms and Explosives.

Errors That Restart the Clock
A large share of NFA delays are self-inflicted. When ATF receives an application with errors, the whole submission is returned to the applicant rather than corrected in place. You fix the problem and resubmit, and the processing clock starts over. The recurring culprits:
- Missing signatures on any field of the form
- Payment errors, including the wrong amount, a declined card, or a check payable to the wrong entity
- Blank fields or information that isn’t consistent across different sections of the form
- Missing serial number for the NFA firearm being registered
- Submitting an obsolete version of the form instead of the current revision
Trust applications multiply the risk. Missing or inconsistent documentation for a single responsible person can send the whole application back. Having a second set of eyes review the packet before submission is worth the ten minutes.
eForms vs. Paper
The ATF’s eForms system lets applicants and dealers submit NFA applications electronically instead of mailing paper.8Bureau of Alcohol, Tobacco, Firearms and Explosives. eForms Applications Built-in validation catches errors before submission, and ATF can process electronic submissions more efficiently.
For Form 4 individual transfers, eForms currently runs at roughly half the processing time of paper. The gap narrows for trust filings and Form 1 applications, where eForms can actually run slightly longer than paper in some periods.2Bureau of Alcohol, Tobacco, Firearms and Explosives. Current Processing Times eForms is generally faster and catches more errors, but it isn’t universally faster for every form type at every point in time. Check the ATF’s posted times before you decide how to file.
How to Shorten Your Own Wait
You can’t control ATF staffing or the current backlog. You can control whether your application clears review or gets kicked back.
- File electronically when the form type currently favors eForms. Individual Form 4 transfers are the clearest case.
- Include your Social Security number. It’s optional, and it helps the FBI clear name-match delays faster.
- Verify every field. Names, addresses, serial numbers, and trust information should match across every page and every supporting document.
- Use clean fingerprint cards. Smudged or partial prints are a common return reason. If your rolling technique isn’t reliable, have them done professionally.
- Consider filing as an individual. If you don’t need shared possession or estate planning, one background check clears faster than several.
- Keep trust membership lean. Every responsible person adds a background check. Include only the people who genuinely need access.
The ATF’s posted processing times move, so check them before you file for a realistic picture of your wait.2Bureau of Alcohol, Tobacco, Firearms and Explosives. Current Processing Times Most of the worst NFA delays trace back to avoidable errors or filing during a demand surge. Getting the paperwork right the first time is the single most useful thing you can do.
