Form 990 For 501(c)(4)s


Quyen Tu, Tim Mooney, Leslie Barnes


On this episode, we’ll share some tips for 501(c)(4) organizations, those nonprofits the IRS calls Advocacy or Social Welfare Organizations. Whether your public charity has an affiliated 501(c)(4) or you work for a stand-alone 501(c)(4), these nonprofits must provide the IRS and the public with their financial and programmatic information annually. And we’re going to talk about how c4s can comply with the IRS requirements, some of the new developments that allow for protection of donor disclosure, and some of the information we, the public, can glean from these reports.
