(Click  this link for a blank ATF Form 1  that is can be completed on your computer with instructions)  When you submit your ATF Form 1, be sure and either print it double sided or copy the second page onto the back after it is printed.   You will also notice that there are 3 copies of the ATF Form 1 so that when you complete the first, it will automatically complete the second and third. The first 2 are sent to the ATF and the third is sent with the CLEO notification..

Here is a Sample ATF Form 1 for a Gun Trust that has been completed. It can be used as a guide to check and make sure your form 1 for a Gun Trust is filled out correctly prior to sending it to the BATFE (ATF).  BATFE will no longer accept older versions of the forms.

Please remember that if your document must be submitted in duplicate and if you print it on multiple pages, it must be photocopied front and back before sending (printed on both sides of the paper).  You must send the completed documents ( 2 copies both originals, your trust, any amendments, and your check for $200 to:

National Firearms Act Branch,
Bureau of Alcohol, Tobacco, Firearms and Explosives

3c Should contain a street address if you plan on storing the Firearm in a PO Box.

3d Should contain the county, parish, or borough you live in or where you will be making the item. Do not put the country.  The county, parish, borough should be used and not USA or United States
