Section 4958 imposes 25% and 200% excise taxes on excess benefit transactions between public charities and disqualified persons, with a 10% manager tax on knowing approvers.

The Section 509(a) public support test requires 501(c)(3) nonprofits to draw more than one-third of support from the public over a rolling five-year window.
