IRS Schedule A for Form 990 or 990-EZ is used by tax-exempt organizations, such as charities and other nonprofit entities, to provide additional information about their public charity status and public support. It is an essential form for these organizations to maintain their tax-exempt status under section 501(c)(3) of the Internal Revenue Code.
This schedule requires organizations to classify themselves as a public charity or a private foundation. The form helps determine an organization’s public charity status based on the source of its financial support, including contributions from the general public, governmental agencies, and other public entities. Schedule A contains several parts designed to demonstrate compliance with the public support test, which requires that a significant portion of an organization’s funding come from the public or other sources that further its tax-exempt purposes.
