Tip: The first two sites are easiest to use.
If you couldn't find your nonprofit's 990 using the resources to the right, you can always try a Google search using 990 and the nonprofit name.
To maintain their tax status with the IRS, nonprofits regularly file a 990 Form. These forms are a good source of info on nonprofits.
Find more info by searching for articles. For small nonprofits, you may need to search newspaper sources.
If it's a well-known nonprofit, try searching the library catalog for a book on the organization.
There are also special resources on this page for charities or associations.
