ATF Form 5320.1—better known as “Form 1”—is the paperwork that starts the “make and register” process under the National Firearms Act (NFA). In plain English: it’s how an individual or entity gets ATF approval to make an NFA firearm and have it entered into the NFRTR (National Firearms Registration and Transfer Record).
ATF’s current revised Form 1 is the “Revised December 2025” version (published/revised Jan. 30, 2026 in ATF’s forms library)—and it includes a few changes that matter for real-world filing and compliance.
This blog breaks down what changed and what it means for firearms owners, dealers, and manufacturers.
Section 1: What is ATF Form 5320.1 (“Form 1”)?
Form 1 is the Application to Make and Register an NFA Firearm. It’s used when you are the “maker” (not a transferee) and you need ATF approval before you build/modify the item described on the form.
Who uses Form 1?
- Individuals
- Trusts
- Corporations / other legal entities
- Government entities
Why it matters: Form 1 is one of those “do it right the first time” items—because NFA compliance isn’t the place to freestyle.
Section 2: Overview of the New Changes
1) Tax Payment Clarification (Items 1a / 1b)
The revised form makes the tax handling more explicit:
- Item 1a (Tax-paid): $200 making tax for each machinegun or destructive device—and it specifically calls out payment options including credit/debit and pay.gov.
- Item 1b (Tax-paid): $0 tax payment for “other types of firearms,” and it clearly states you don’t complete the payment section (Item 19) when the tax is $0.
- New/clearer tax-exempt pathway: There’s also an explicit tax-exempt option referencing 26 U.S.C. 7801/7805, with a note ATF may request supporting documentation (e.g., documents, photos, etc.).
2) Revised Structure and “User-Friendly” Clean-Up
This version is visibly designed to be easier to follow, with clearer instructions and modern submission language (including eForms references).
3) Updated Electronic Signature Options
The instructions now clearly allow:
- ATF eForms-generated signatures
- Handwritten ink signatures
- Other electronic signatures
4) Other Notable Updates (the “small stuff” that causes big delays)
- Race/ethnicity selections were updated (including a Middle Eastern/North African option and “select one or more”).
- Fillable/print handling improved: the form may be downloaded and filled/signed electronically, and it does not have to be printed front-to-back.
- Pay.gov integration details: the payment section notes that eForms/pay.gov filings may have an internal tracking number not listed in the payment box.
Section 3: Why These Changes Matter
Less friction, fewer “kicked back” applications
The updated tax language and signature guidance reduce the classic errors that trigger rejections/returns (wrong payment handling, wrong signature method, incomplete payment fields).
Time + convenience
The form explicitly supports modern workflow: pay.gov, electronic fill/sign, and clearer “what applies when” instruction language.
Married couples filing jointly (newer instruction direction)
DOJ/ATF paperwork notices specifically call out adding instructions for married couples jointly making/transferring/registering an NFA firearm as an “other legal entity.”
Practical takeaway: if you’re trying to file “jointly,” expect to follow the entity lane (not the individual lane), with the appropriate responsible-person documentation where applicable.
Section 4: How These Changes Affect You
For individual applicants
- Clearer “what to fill out / what to skip” based on tax status and submission method.
- Explicit acceptance of eForms/e-signature pathways (per instructions).
For trusts, corporations, and other entities
- The instructions reiterate entity existence documentation requirements and responsible-person packet expectations (Form 5320.23, etc.).
- Joint-filing guidance (including married couples) is being emphasized across ATF/DOJ modernization updates.
For firearms dealers / manufacturers
- Cleaner payment and submission mechanics help reduce customer delays and “what did ATF mean here?” confusion.
- The form still expects correct entity documentation and responsible-person handling—areas that commonly create downstream compliance headaches if mishandled.
Section 5: What You Need to Do Next
How to submit Form 1 (updated workflow)
- Get the current Form 1 directly from ATF’s forms library.
- Choose the correct application type (tax-paid vs. tax-exempt) and follow the updated payment guidance (especially $0 = don’t fill Item 19).
- Use an approved signature method (eForms / ink / other electronic signature).
- If applying as an entity: attach required entity existence documentation, and ensure responsible person requirements are handled correctly.
Key documents you may need
- Entity documentation (trust/corporate/other legal entity) if applicable
- Any supporting documentation if claiming a tax-exempt status under the listed authority
