How to Fill eForm 1 - ATF eForms Guide

ATF eForms allows individuals and members of the firearms industry to file certain forms electronically rather than via paper applications. The electronic filing is designed to be more efficient and accurate and will allow ATF to process the submissions more efficiently.

Once you’ve figured out how you want to build your homemade suppressor, you need to file some paperwork with the Bureau of Alcohol, Tobacco, and Firearms. The paperwork in question is called ATF eForms - Form 1.

Navigate to the E-Forms website:

Whether you are a trust or an individual, you need to register before completing the form. First, register an account with the ATF, this is mandatory and you can do it on their website. In case the state doesn’t allow you to input the state name, you can add the zip code. When you can’t create a user ID, you will see that the ID is generated automatically after form completion. Passwords need to be complex, they need to have at least 12 characters, a number, special character, and upper/lower case letters.

What do you need to file as an individual? What about filing as a trust?

You must scan and then upload your photo, share the name and address of your county sheriff, the suppressor manufacturer name, model, serial number, caliver of the suppressor and the suppressor length.

If you want to file as a trust, you upload all the Responsible Party ATF eForms to the computer, ATF form 5320.23 is a crucial aspect here. You also need to save a scanned photo of every trustee to the computer. In addition, you must upload the trust documents, and also have completed fingerprint cards. Aside from that, you will also need to offer all the stuff listed above when you file as an individual. It’s very important to ensure that the information is accurate and to the point, as it will offer you all the information you want and results can be very impressive.

How can you start the ATF eforms application? Here are the steps to follow!

Before you do anything, you will need to log in using the credentials from the previous registration. Then you must choose the ATF eforms - form 1.

  1. Once you select the ATF eform 1, you will need to choose if you want to apply either as a trust or as an individual. Make sure that you pick the right option because there will be different requirements according to what you are picking.
  2. Then you must choose the type of application. No matter if you are filing as a trust or individual, you still need to Select Paid Tax, $200. This is mandatory, and it’s something you must pay, trust or not. In case you do have an internal control number, you can share it on this page as well. If not, you can leave it blank and move on, depending on the situation.
  3. On the Applicant screen you must choose the non-FFL radio button at the top of the screen. This is valid for both the individuals and trusts trying to file this, so keep that in mind. If you file as a trust, you must send the title of the application submitter, trust name, complete the data with trust information, and so on. If you file as an individual, most of the info will be acquired from your profile. There will be some Maker’s Questions, but these are mostly Yes/No questions.
  4. On the Responsible person screen (ONLY FOR TRUSTS), you must make sure that you are adding all the information regarding the responsible parties in your trust. What this means is that you must include all trustee information separately. You will upload the 5320.23 form and a trustee photo. The ATF doesn’t require an SSN, so this is not mandatory. The same thing can be said about a UPIN, most people don’t have one, so you can leave the box blank if you want, which is something to keep in mind. You are able to add/remove any responsible persons via the Action button found above the Citizenship dropdown.
  5. The Chief Law Enforcement Officer information is something only for individuals. Anyone in a trust already offered this via the dedicated 5320.23 form. Make sure that all sections here are completed with information that was previously collected.
  6. Line Item is a section where you want to enter the info about the ATF eform 1 item. You must press Add Firearm, and a new window opens, here you can insert information about the firearm. In the Manufacturer Code section, you need to type FMI so you can submit this as an ATF eforms 1. You also want to select Verify Manufacturer so you can unlock the country. In case you are building this on your own, the country will be the USA.
  7. On the next part of the Line Item screen you must choose the Product Type, just use the drop-down menu to access that. Select the Radio Button if the item is not in the list and you want to create a new one. When you create a new item, you want to add the model, caliber, units of measure, general length and barrel length, serial number, description and the state where you want to make the firearm.
  8. After that on the Electronic Documents page (FOR TRUSTS) you must upload a copy of the notarized and signed trust documents. In some cases, you just need to have an application approved as a transferee or a maker and you can’t change that to the previously provided documentation.
  9. Lastly, you have the Certify page. Read all the information as it is very important. You will also have to Click to Pay in order to submit your payment information. After that, you need to Sign & Submit, then you are good to go.

What happens after you send the ATF eforms?

It’s important to note that you will receive an email from the ATF after you offered the payment instructions. Check the junk mail if you didn’t get it for some reason. You have 10 business days to send two fingerprint card copies via mail. Trusts will need to send these to each one of the applicants. After that, the ATF eforms system will send you an attached approval form with the tax stamp. Founded in 2019 by Kyle Matthews. K.M.
