ATF eForm 1 Guide: How to Apply to Make and Register an NFA Firearm in 2026

The ATF eForm 1 is an electronic application used by individuals, trusts, or legal entities to obtain federal permission to manufacture an NFA firearm, such as a short-barreled rifle or suppressor. By filing through the ATF eForms portal, applicants pay a $200 tax and submit fingerprints to receive a digital tax stamp.

The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) eForm 1 system—formally known as "Application to Make and Register a Firearm"—remains the primary gateway for law-abiding citizens to legally create firearms regulated under the National Firearms Act (NFA) of 1934. Whether you are shortening the barrel of an existing rifle, building a dedicated short-barreled shotgun, or manufacturing a silencer from scratch, the eForm 1 process is significantly faster and more efficient than the traditional paper-based filing.

As we navigate 2026, the electronic system has matured, integrating digital fingerprinting and streamlined payment processing to reduce wait times from months to often just a few weeks. However, the legal stakes remain high. Errors on an eForm 1 can lead to immediate rejections, forfeited wait times, and potential legal complications regarding the possession of unregistered NFA items.

Understanding the Scope of the ATF eForm 1

The eForm 1 is specifically for "making" a firearm. This differs from the eForm 4, which is used for "transferring" a firearm that has already been manufactured by a licensed company (SOT). When you file an eForm 1, you are legally designated as the manufacturer of that specific firearm.

Regulated Firearms Under the NFA

Not every firearm requires a tax stamp. The eForm 1 is used for the following categories:

• Short-Barreled Rifles (SBR): Rifles with a barrel length under 16 inches or an overall length under 26 inches.
• Short-Barreled Shotguns (SBS): Shotguns with a barrel length under 18 inches or an overall length under 26 inches.
• Silencers/Suppressors: Any device for silencing, muffling, or diminishing the report of a portable firearm. This includes "Form 1 builds" where the applicant machines the components.
• Any Other Weapon (AOW): A catch-all category for specific concealable weapons, such as pen guns or smooth-bore pistols. Note that the tax for making an AOW is $200, though the transfer tax (Form 4) is only $5.
• Machine Guns: Under the Firearm Owners' Protection Act of 1986, individuals cannot "make" new machine guns. Therefore, eForm 1 is generally not used for machine guns by private citizens.

Prerequisites for a Successful Application

Before logging into the ATF eForms portal, you must gather several digital assets and legal documents. Preparation is the most critical phase; the portal is notorious for "timing out" if you spend too long searching for information while a session is active.

1. The eForms Account

You must register for an account at the ATF eForms website. Ensure that the name and address used for the account profile exactly match the information you will provide on your application. In 2026, the ATF requires multi-factor authentication (MFA), so ensure you have access to the associated email address.

2. Digital Passport Photo

You will need a digital photograph taken within the last six months. This must be a clear, front-facing image of your face against a neutral, light-colored background. No hats or sunglasses are permitted. The file should be in .jpg or .png format and generally under 3MB in size.

3. Fingerprint Files (.EFT)

While the ATF still accepts physical FD-258 fingerprint cards mailed to Martinsburg, WV, the 2026 standard is the Electronic Fingerprint Transmission (.eft) file. These files can be generated at many local gun stores, shipping centers, or via specialized kiosks. Using an .eft file allows you to upload your prints directly to the eForm, which significantly accelerates the background check process conducted by the FBI’s NICS system.

4. Legal Entity Documentation

If you are filing as a Trust or a Corporation, you must have a high-quality PDF scan of your full trust instrument (including all schedules and amendments). If you are filing as an Individual, this documentation is not required.

Step-by-Step Walkthrough of the eForm 1 Process

The application is divided into several screens. Accuracy on each screen is paramount, as the ATF does not allow "edits" once the form is submitted and paid for.

Screen 1: Application Type and Internal Control Number

On the initial screen, you select the "Form 1." You will be asked for an "Internal Control Number." This is optional and is purely for your own filing system. Most individual applicants leave this blank.

Screen 2: Applicant Type

Here, you choose whether you are filing as an Individual, Trust, or Corporation.

• Individual: Only you may possess the firearm. No additional forms for other people are required.
• Trust/Legal Entity: Allows for "Responsible Persons" (Co-Trustees) to also possess the firearm. Every Responsible Person listed in the trust must submit a "Responsible Person Questionnaire" (Form 5320.23), a photo, and fingerprints.

Screen 3: Responsible Persons

If filing as an Individual, your information will auto-populate from your profile. Ensure your Social Security Number is included; while technically optional, omitting it often leads to significant delays in the NICS background check.

If filing as a Trust, you must add a row for every trustee. You will upload their digital photos and .eft fingerprint files (if available) here.

Screen 4: The Firearm

This is where the most common errors occur. You must describe the firearm you intend to make.

• Manufacturer: If you are converting an existing rifle (like an AR-15) into an SBR, the manufacturer is the company that made the lower receiver (e.g., Aero Precision, Colt). If you are building a suppressor from scratch, you select "User Defined" and enter your own name or trust name as the manufacturer.
• Product Type: Select SBR, SBS, Silencer, etc.
• Model: Use the exact model name engraved on the receiver. Do not invent a model name.
• Caliber: Select the specific caliber (e.g., 5.56, .30, 9mm). Avoid "Multi" even if your receiver is marked that way; the ATF requires a specific caliber for the initial registration.
• Measurements: You must provide the barrel length and the overall length (OAL) with the stock fully extended. These can be estimates, but they should be as accurate as possible for the intended configuration.

Screen 5: Electronic Documents

On this screen, Trust applicants upload their trust documents. Individual applicants usually move past this screen unless they have specific state-required permits to upload.

Screen 6: Certification and Payment

You will review your entries and proceed to the Pay.gov portal to pay the $200 tax. After payment, you will return to the eForms site to sign the application electronically using your PIN.

Identifying the Best Filing Method

Choosing between an Individual filing and a Trust filing is a long-term legal decision. The following table highlights the primary differences as they stand in 2026.

Post-Submission: What Happens Next?

Once submitted, your eForm 1 status will change to "Submitted/In Process."

1. The Cover Letter

If you did not upload .eft fingerprint files, the ATF will email you a "Cover Sheet" with a control number. You must print this and mail it to the ATF along with two physical FD-258 fingerprint cards within 10 business days. If you uploaded .eft files, you do not need to mail anything.

2. CLEO Notification

The ATF no longer requires permission from your local Sheriff, but they do require notification. You must print the "CLEO Copy" of your generated Form 1 (emailed to you after submission) and mail or hand-deliver it to your Chief Law Enforcement Officer (usually the County Sheriff or City Chief of Police). They do not need to sign it or respond; you simply fulfill the duty of notifying them.

3. The "Pending Research" Phase

If your firearm model or manufacturer was not in the ATF's dropdown menu, your application will go into "Pending Research." An ATF specialist must manually verify that the manufacturer exists. This typically adds 2 to 7 days to the process.

Manufacturing and Engraving Requirements

You cannot legally "make" the firearm until you have the approved, digital tax stamp in your possession. Once the email arrives with the "Approved" attachment, you must fulfill your duties as a manufacturer.

Under 27 CFR 479.102, you must engrave the following information on the frame, receiver, or barrel:

1. Your Name (if filing as an individual) or the Name of your Trust/Legal Entity.
2. City and State where the firearm was made.

The engraving must be to a minimum depth of .003 inch and in a print size no smaller than 1/16 inch. Most applicants use a professional laser engraving service to ensure compliance. You must engrave the information even if the original manufacturer's info is already there; your info signifies who "made" the NFA-configured version of the firearm.

Common Mistakes and Rejection Triggers

The ATF is strictly binary: your form is either perfect or it is rejected. They rarely ask for corrections on an eForm 1.

• Incorrect Serial Number: Triple-check the serial number on your receiver. Do not confuse "0" (zero) with "O" (the letter).
• Name Mismatch: If your Trust is "The John Doe Revocable Trust," do not type "John Doe Trust" on the form.
• Illegal Calibers: In some jurisdictions, certain calibers or configurations are banned. The ATF will reject forms that violate state law (e.g., an SBR in a state where they are prohibited).
• Vague Descriptions: Do not use descriptions like "various" for barrel length. Provide a specific number in inches.

Frequently Asked Questions

How long is the current wait time for an eForm 1 in 2026?

As of 2026, Individual eForm 1 applications utilizing .eft digital fingerprints are often processed in 10 to 30 days. Trust applications may take slightly longer, typically 30 to 60 days, depending on the complexity of the trust and the number of responsible persons. These times are estimates and can fluctuate based on ATF staffing and application volume.

Can I travel across state lines with my eForm 1 firearm?

For SBRs, SBSs, and AOWs, you must file ATF Form 5320.20 and receive approval before transporting the firearm across state lines. This form can be approved for up to one year. Interestingly, silencers do not require this form for interstate travel, though you must still comply with the laws of your destination state.

What if I want to change the barrel length later?

The ATF requests (but does not strictly require) that you notify them if you make a "permanent" change to the firearm's configuration, such as changing the caliber or barrel length. If you are simply swapping uppers on an SBR and keep the original upper, no notification is necessary. If you sell the original upper and permanently change the length, a simple letter to the NFA Division is recommended to keep the National Firearms Registration and Transfer Record (NFRTR) accurate.

Can I cancel an eForm 1 and get a refund?

Yes. If your application has not yet been approved, you can request a withdrawal via the eForms "Ask the Experts" tab. Once withdrawn, the $200 tax is typically refunded to the original payment method within 30 days. Once the form is approved and the "stamp" is issued, the tax is generally non-refundable unless the firearm was never actually manufactured.

Do I need to keep a printed copy of my tax stamp?

While the 2026 eForm 1 provides a digital PDF with an electronic signature/stamp, you should keep a printed copy with the firearm whenever it is in transport. Law enforcement officers may not be familiar with digital stamps, and having a physical copy prevents unnecessary complications during a field inspection.

Final Recommendation

Before you click "Submit," perform a final audit of your digital photo and serial number. In 2026, the use of .eft digital fingerprint files is the single most effective way to ensure a rapid approval. If you are new to the NFA world, consider filing as an individual for your first "maker" project to familiarize yourself with the process before navigating the complexities of multi-person trusts. Always ensure your engraving is completed immediately after receiving your approved stamp and before you assemble the NFA-regulated components.
