The main purpose of this legislation is to change the tax status of the Southern Poverty Law Center (SPLC). The bill aims to ensure that the SPLC is no longer recognized as a tax-exempt organization under section 501(c)(3) of the Internal Revenue Code. This change is intended to stop what the bill's sponsors describe as the misuse of charitable status for political activities. Key provisions of the bill include the explicit declaration that the SPLC will not be treated as a tax-exempt charity. This means that the organization would be subject to taxation like any other for-profit entity.
