How does an organization register as a charity?
An organization must file an Application for Registration of a Charitable Organization, along with its organizing documents (e.g. a charter) and, if it has obtained one, a letter of determination of tax-exempt status from the IRS. If an organization has completed an accounting year, it must file also file a Summary of Financial Activities form, an IRS form 990 (if the organization is required to file such), and an audited financial statement if its revenues exceed $500,000, excluding government grants and grants from private foundations.
