How to fill out the
ATF Form 1

Only $49 – Get your Gun Trust Now

Filling out a Form 1 can be really frustrating, even for people that have previously submitted Tax Stamp Applications.   That’s why the Trust Shop created this Form 1 instruction guide.   The Trust Shop guys are here to make the process of building your SBR, SBS, Silencer, or Machine Gun easy.

The following “How To” Guide is broken down into step-by-step directions according to the Box # on the Form 1 Application.   If you are having trouble with a particular Box on the Form 1, you can scroll down to the example with the same number.   It is important to note that this guide only applies to Form 1 Applications being made by a Gun Trust.   If you are applying for a Tax Stamp as an individual, you need to read our article: How to Fill out a Form 1 as an Individual.

If you got your Gun Trust from the Trust Shop,
you can use our automated Form 1 builder free of charge.

ATF Form 1 Generator

Boxes 1 – 3

Form 1 Boxes 1-3

Box 1 – Type of Application
Always place a checkmark in box a.   You will never check boxes b or c

Box 2 – Application is made by
Place a checkmark in the box next to “Trust or Legal Entity.”   It is important to note that this guide is designed to help people that are filling out a Form 1 using a Gun Trust.   This “How To” guide doesn’t apply to people applying for Tax Stamps as individuals.

Box 3a – Trade Name
Leave this box blank

Box 3b – Applicant’s Name and Mailing Address
Enter the name of your Gun Trust exactly as it appears on the cover sheet of your Trust Shop NFA Gun Trust. Do not enter your name in this field! Enter the address where the firearm will be stored. If the firearm will be stored at multiple locations, enter the address where it will be stored the majority of the time.

Box 3c – If 3b is a PO Box
You will only enter an address in Box 3c if the address you entered in Box 3b is a PO Box.   This is because the ATF wants a physical address for the location of the ATF item.   So just enter the address in Box 3b and leave this box blank.   If for some reason you have a burning desire to give the ATF two separate addresses; put the PO Box in 3b and the Physical Address in 3c.

Box 3d – County

Alaska residents: enter the name of your Borough
Louisiana residents: enter the name of your Parish
Virginia residents: if you live in an independent city, enter the name of your city.

Box 3e – Phone Number
Enter a phone number where you can be reached during business hours.

Box 3f – e-mail Address
This field is optional, so we say leave it blank !

Box 4

Box 4a – Name and Address of Original Manufacturer and/or
Importer of Firearm

Form 1 Box 41st Situation – Manufacturing a New Item
If you are making a silencer from scratch or building a SBR using an 80% complete lower receiver, your Gun Trust should be listed as the Manufacturer.   In this situation you will enter the Name & Address of the Gun Trust exactly as they will be engraved on the completed Silencer or Lower Receiver

Note: The address you engrave on your Silencer/Lower Receiver is not necessarily exactly the same as the Name & Address you entered in Box 3b.   This is because you will have to follow the engraving requirements found in 27 CFR 478.92 & 27 CFR 479.102.   The ATF has a good summary page on engraving here.

Form 1 Box 42nd Situation – Modifying an existing Item
Even though you are applying for permission to ‘Manufacture’ an NFA item, many times you are actually modifying an item that was originally manufactured by someone else.   For Example:   You own a Ruger AR556 with a 16″ barrel.   You want to convert the rifle into a SBR by switching the factory barrel with a Noveske 10.5″ Barrel.   Even though you are required to Fill out a Form 1 Application to Make & Register a Firearm, the original manufacturer is Ruger.   So, you would enter the Name and Address of Ruger in this box.

Note: In the 2nd situation, the information you enter in Box 4a must be entered exactly as it is engraved on the firearm.

Note: Be certain that you enter the Name & Address of the Manufacturer not to enter the Name & Address of the Importer.

Box 4b – Type of Firearm to be Made
The type of firearm should be one of the following:
Short-Barreled Rifle
Short-Barreled Shotgun
Machine Gun
AOW (Any Other Weapon)
Destructive Device

Box 4c – Caliber or Gauge
Enter either the Caliber or Gauge in this field.   For example: 7.62 mm, .308 cal, and 12 Gauge are all acceptable formats.

Note: If you have a caliber like 6.5 mm Creedmoor you should list it as 6.5 mm.   Do not add “Creedmoor” to the end of the caliber designation.

Note: If you are applying for a NFA item that has multiple calibers, you should list only one caliber in Box 4c.   The ATF no longer accepts “Multi” in Box 4c.   If you have more than one caliber, you can list the additional calibers in Box 4h or you can list them on a separate sheet of paper and attach it to your Form 4.   Just make sure you write “See Attached List” in Box 4h.

Box 4d – Model

1st Situation
If you are making a silencer from scratch or building a SBR using an 80% complete lower receiver, you will have to make up a Model Number.   There are a few requirements that need to be followed when selecting a custom Model Number, that can be found here.

2nd Situation
If you are modifying an existing item, you need to enter the Model Number exactly as it is engraved on the Lower Receiver.   If there isn’t a Model Number engraved in the Lower Received you are modifying, you should enter ‘N/A

Box 4e – Length of Barrel
According to the ATF, the length of the barrel is measured by inserting a dowel rod into the barrel until the rod stops against the bolt or breech-face. The rod is then marked at the furthermost end of the barrel or permanently attached muzzle device, withdrawn from the barrel, and measured.

If you are making a Silencer you should enter ‘N/A

Box 4f – Overall Length
According to the ATF, the overall length of a firearm is the distance between the muzzle of the barrel and the rearmost portion of the weapon measured on a line parallel to the axis of the bore.
If you are making a Silencer, enter the length of the total length of the silencer.

Note: if the firearm has a folding or collapsible stock, the overall measurement needs to be made with the stock opened or fully extended.

Box 4g – Serial Number

1st Situation
If you are making a silencer from scratch or building a SBR using an 80% complete lower receiver, you will have to make up a Serial Number.   There are a few requirements that need to be followed when selecting a Serial Number, that can be found here.

2nd Situation
If you are modifying an existing item, enter the Serial Number in Box 4g, exactly as it is engraved on the Lower Receiver

Box 4h – Additional Description or Data Appearing on Firearm
The directions on the Form 1 say: Markings: The maker is required to mark the firearm with his or her name, city and state. All markings are to be in compliance with 27 CFR 478.92 and 479.102.

So what does this mean? Even though the directions don’t explicitly state that the Name, City, and State must be entered in Box 4h, this is one of those better safe than sorry situations.   Everything that will be engraved on the Silencer or Lower Receiver, including the Name, CIty, State, Model, and Serial Number, should be entered in Box 4h

Box 4i – Why you intend to make the Firearm
Enter All Lawful Purposes

Box 4j – Type of destructive device
Unless you are making a Destructive Device you should leave this Box blank.   If you are making a Destructive device, you need to state whether the DD is a Firearm or an Explosive.   If it is an ‘Explosive’ you need to enter the type of explosive

Box 4k – Is this firearm being reactivated?
Place a checkmark in the box marked NO

Boxes 5-6

Form 1 Boxes 5-6

Box 5 – Applicant’s Federal Firearms License or Explosives License or Permit Number
Because you are applying as a Gun Trust this box should be left blank

Note: Box 5 is also the location where you would enter an Explosives License Number, if you were making an Explosive Destructive Device.   However, as a trust cannot be issued an Explosives License or Permit, this would have to be the Explosives License Number of one of the Responsible Persons in the Gun Trust.

Box 6a & 6b – Employer Identification Number & Class
Because you are applying as a Gun Trust you should leave both of these boxes blank.

Boxes 7-9

Form 1 Boxes 7-9

Box 7 – Signature of Applicant
Sign your name not the name of the Trust, immediately followed by the words as Trustee.   You can look at the picture above to see what the signature block should look like.

Box 8 – Name and Title of Authorized Official
Print your name not the name of the Trust, immediately followed by the words as Trustee

Box 9 – Date
Enter the date.

Box 10

Form 1 Box 10

Box 10 – Law Enforcement Notification

With the implementation of 41F, you are required to send a copy of your Form 1 Application to your Chief Law Enforcement Officer (CLEO).   Box 10 is where you enter the information about your CLEO.   Remember: you do not need to get the CLEO’s signature, you only need to send them a copy of the Form 1.   After we get done with the Form 1, we will cover which documents need to be sent to your CLEO & the ATF.

You need to enter three pieces of information in Box 10:
1.   The Name of your CLEO’s Agency.
2.   The Name and Title of your CLEO.
3.   The Address of your CLEO.

Boxes 11, 12, 13, & 14

Form 1 Box 11, 12, 13 & 14

Boxes 11-14 Should be left Blank.   But, don’t get too excited… You’re gonna have to provide all of this information later when you are filling out your Form 23.


Form 1 Certification

At the bottom of Page 2 you need to sign your name followed by “as Trustee.”   Then enter the date.

Boxes 15 & 16

Form 1 Box 15-16

Box 15 – Number of Responsible Persons
Enter the number of Responsible Persons (including yourself) in Box 15.   If you aren’t sure which people in your Gun Trust are considered Responsible Persons, you can check out our article Who is a Responsible Person & Why does it matter?

Note: If you got your Gun Trust here at the Trust Shop, the Settlor, Trustee, & Co-Trustees are the only Responsible Persons.

Note: If you filled out a Form 1 in the past you may not have been required to fill out the Responsible Person section.   That’s because ATF Final Rule 41F went into effect On July 13, 2016, which requires all Responsible Persons to submit a Form 23 (along with mugshots & fingerprints).

Box 16 – Name of each Responsible Person
For each of the Responsible Persons (including yourself), enter their full legal name (first, middle & last).   If a Responsible Person doesn’t have a Middle Name, you can enter “NMN” which stands for No Middle Name.

Box 17

Form 1 Box 17

Box 17 – Method of Payment
Check the appropriate box for the type of payment you are submitting.   If you are paying by check, Cashier’s Check, or Money Order, you don’t need to fill out anything other than Method of Payment.   If you are paying by Credit Card, you will need to fill in the remaining fields concerning billing information.   Remember: You only need to sign Box 17 if you are paying by Credit Card.

Note: if you submit any information incorrectly, your Application will be delayed or denied.   This is one of the reasons we suggest sending a check or money order instead of paying with a credit card.   There are just too many chances to make a mistake when entering all those credit card numbers.

And now your Form 1 is complete!

In all, the Form 1 includes of three copies of the 3-page form we just discussed, and three pages of directions, for a total of 12 pages.   You will send two copies of the form (ATF Copy and ATF Copy 2 – To Be Returned To Registrant) to the ATF.   The ATF keeps one copy on file and returns a copy with your Tax Stamp affixed to the front page.   The third copy (CLEO Copy) gets sent to your CLEO.   Because the three copies of the Form 1 are identical (except for a few items not included in the CLEO copy) you can use the ATF interactive Form 4 and you only have to enter the information once.   The 2nd and 3rd copies are automatically populated with the information from the 1st copy.

The perfect SBR resource

On first sight, the website doesn't look as slick as a lot of modern websites. Thank god for that. This is in all honesty one of the most sensible and well-built websites I've ever seen. Incredibly user-friendly, straight-forward, but filled to the brim with a quick answer to your every question right as you thought to ask it. Incredibly helpful and a pleasure to use. I wish all companies were half as good as this.
