according to this article http://inside.envato.com/usa-tax-withdrawal-changes/
"When will Envato not apply US RWHT?
US RWHT won’t be applied on items sold with a Tools license (such as items in GraphicRiver’s Add-ons category). Income made from selling this kind of license is classified in a different way and doesn’t give rise to this tax."
Is the GR add-ons category the only one free of new taxes or are there any other categories that will remain the same? Please specify.
