This has a VERY serious impact on NFA firearms owners. Many people, especially those that own a large collection of NFA firearms or accessories, assign a family trust as the owner. This way the firearms can be passed between generations without paying for a new tax stamp every time they are passed on.
Say I had 10 NFA firearms when I died, that is $200 per firearm or accessory that my family must pay to transfer to whoever gets them or they must be turned over to the feds for destruction. If i had a trust set up, whoever receives those weapons would simply have to send in a form to change the primary contact for the trust and the address the weapons would be stored at.
