When filling out a Form 1 for the first time with your NFA trust it can be confusing. With an ATF Form 4, there is typically a dealer involved or someone who has done it before so there are not as many questions. I have created a page on How to fill out a Form 1 with a link to a 5320.1 Form 1 that you can download and a sample that is filled out that can be used as a guide. The page also includes instructions on what information should be contained in your Form 1.
