Poor Peter LaBarbera... He'll no longer be allowed to give donors tax deductions for fueling his anti-gay hatred. Porno Pete's Americans for Truth about Homosexuality (AFTAH) had it's 501(c)3 status revoked in May of 2010 according to Ex-Gay Watch:
The reason for this action is listed by the reporting organization Guidestar as a "failure to file a Form 990, 990-EZ, 990-N, or 990-PF for 3 consecutive years." These forms are required of legitimate non-profit organizations for review by the IRS and the public.
According to the IRS documentation on revocations (PDF), AFTAH can no longer be considered a 501(c)3 tax-exempt organization, and there is no process for appeal. Donations made to them before 6/10/2011 are still deductible by donors, though any income after revocation may be taxed and require filing of a federal return. LaBarbera appears to have been aware of all this, as the donations section of the AFTAH website no longer claims tax-exempt status.
In 2009, 68% of AFTAH's donations went directly into Pete's pocket as his salary. In late 2010, AFTAH was designated an official "hate group" by the Southern Poverty Law Center.
