The IRS maintains an electronic database of every organization that has been provided with tax-exempt status. To know about your organization's tax-exempt status, make use of the Tax Exempt Organization Search of the IRS.
Tax Exempt Organization Search is an online search tool that allows users to search and obtain information about an exempt organization’s federal tax status and filings.
Also, the organization can check for its tax-exempt status by directly calling the IRS at 1-877-829-5500. Once done, an IRS agent will look up for your organization's exempt status if you provide the name, address, and EIN of your organization.
