On September 18, 2018, the United States Supreme Court overturned a stay blocking a District Court ruling requiring non-profits to disclose identity of all contributors who give more than $200 a year. Prior to the ruling, IRS designated 501(c)(4) social welfare organizations and 501(c)(6) organizations such as business leagues and boards of trade, who do not register as political committees with the Federal Election Commission (FEC), were required to disclose donors only when they contributed for specific political advertisements. While the ruling requires the FEC to give guidance, newly issued FEC rules limit the scope of the court’s intention. It is likely that the new ruling will allow some donors to remain undisclosed while requiring partial disclosure of donors who contribute towards certain, but not all, expenditures.
