Tax-exempt organizations
A federal judge has ruled that the IRS does not have to disclose publicly the reasons for revoking or denying tax exempt status to a charity.
The I.R.S. typically denies or revokes tax-exempt status only in cases where an organization engages in prohibited political activity, is operating for profit or in a fraudulent manner. The agency may impose sanctions for violations instead.
...The I.R.S. recognizes more than 1.35 million tax-exempt organizations. About 820,000 of those are classified as charities, and donors can take a tax deduction.
