Back in April the backlog on Form 1 and Form 4 transfers was around 43000. The additional staff has almost doubled the number of transfers per month that the agency can handle. The ATF is also asking Congress to use part of the revenue generated to help update their antiquated systems as currently the taxes collected from the Form 4 and Form 1 applications is deposited into the Treasury’s account where the ATF has no access.
Apparently if a FFL submits a Form 1 or Form 4, their applications are put in a special folder for special processing because the background of the FFL has already been checked.
