For 501(c)(3)s, the four main activities that can jeopardize the organization’s tax-exempt status are:
- activity that results in private benefit or inurement;
- lobbying activity, if it constitutes a substantial part of the organization’s overall activities or if it exceeds a predetermined dollar amount;
- any political campaign activity; and
- unrelated business activity that is substantial when compared with the organization’s exempt-function activities.
