In a number of situations, an NFA item may be transferred without a transfer tax. These include sales to government agencies, temporary transfers of an NFA firearm to a gunsmith for repairs, and transfer of an NFA firearm to a lawful heir after the death of its owner. A permanent transfer, even if tax-free, must be approved by the ATF. The proper form should be submitted to ATF before the transfer occurs. For example, lawful heirs must submit a Form 5 and wait for approval before taking possession of any NFA item willed to them. Temporary transfers, such as those to a gunsmith or to the original manufacturer for repair, are not subject to ATF approval since they are not legally considered transfers. The ATF does, however, recommend filing tax-free transfer paperwork on all such temporary transfers, to confer an extra layer of legal protection on both the owner and the gunsmith.
