Americans United has worked to uphold the federal law that bars non-profit groups, including houses of worship, from intervening in partisan politics. In 1992, the group reported a New York church, the Church at Pierce Creek, to the Internal Revenue Service (IRS) after the church ran newspaper ads telling people not to vote for Bill Clinton. The IRS subsequently stripped the church of its 501(c)(3) determination letter. After the church filed suit in federal court to get the determination letter back, the court noted, "because of the unique treatment churches receive under the Internal Revenue Code, the impact of the revocation is likely to be more symbolic than substantial... Contributions will remain tax deductible as long as the donors are able to establish that the Church meets the requirements of section 501(c)(3)." Churches do not need a tax-exempt determination letter to receive all of the benefits of tax-exempt status.
