This legislative proposal aims to revoke the 501(c)(3) tax-exempt status of the Council on American-Islamic Relations (CAIR). If enacted, CAIR would no longer be recognized as a tax-exempt organization under section 501(c)(3) of the Internal Revenue Code of 1986, meaning it would be subject to federal income taxation like a for-profit entity. This significant change would alter the organization's financial and operational framework, potentially impacting its ability to receive tax-deductible donations and its overall funding. The bill explicitly states that, notwithstanding any other provision of law, CAIR shall not be treated as described in section 501(c)(3). This provision would apply to all taxable years ending after the date of the Act's enactment, ensuring a clear effective date for the change in tax status and immediately affecting its financial standing.
