Note: For groups that want to be politically active, alternative corporate structures are available, such as super PACs and “527” groups — and those groups aren’t limited to spending just 49.9 percent of their resources on politics. However, they are required to disclose their donors.
Political Nonprofits: Top Donors
These are the top donor organizations to politically active 501(c) nonprofits — or, rather, these are the donors the Center for Responsive Politics has been able to identify. Groups on the receiving end aren’t required to publicly reveal who their contributors are. However, 501(c) groups must disclose the names of organizations to which they make donations. By sifting through hundreds of 990 tax forms, where the disclosure occurs, we have come up with this list.
Other donors — such as individuals and corporations — aren’t required to publicly report such gifts, so the sources of much of the money flowing to politically active tax-exempt groups remain unknown.
