In general, what public disclosure requirements apply to tax-exempt organizations?
In general, exempt organizations must make available for public inspection certain annual returns and applications for exemption, and must provide copies of such returns and applications to individuals who request them. Copies usually must be provided immediately in the case of in-person requests, and within 30 days in the case of written requests. The tax-exempt organization may charge a reasonable copying fee plus actual postage, if any. The IRS must also make this same information publicly available. Generally, it may take the IRS up to 60 days to process your request.
