Do You Need to Keep Expired ATF 5320.20's?
The ATF Form 20 or the ATF 5320.20 Application to Transport NFA Firearms is required when you are transporting your NFA firearms across state lines or to an address that is different then the address on your ATF Form 4 or ATF Form 1 that contains the ATF Tax Stamp. Once you have submitted the ATF 5320.20, you will receive an approved or denied ATF 5320.20 to mailing address indicated on the form. If your ATF 5320.20 form is approved, you will be able to transport the NFA firearms mentioned in the approved form for the duration of the approved form. After the "To" date has passed the ATF 5320.20 has expired and is no longer valid. The expired ATF 5320.20 doesn't need to be kept, but can be kept for your records if you chose to keep them.
