On August 15, 2018, the IRS automatically revoked the federal tax exemption status of Worldwatch Institute for "failure to file a Form 990-series return or notice for three consecutive years." For this reason, we have issued a High Concern CN Advisory. For more information, please see the IRS register for tax-exempt organizations.

The concerns raised about organizational legitimacy and/or federal tax law compliance are serious both in nature and scope and have thus warranted this CN Advisory. We have published this advisory to provide donors with content that they may find useful when making their giving decisions. Charity Navigator is not responsible for the nature or content of the information presented through external sources and websites. For more information on how or when we decide to publish a CN Advisory, please review our methodology.
