It seems like Google has released a new form of their knowledge graph, one that shows non-profit information when you search for non-profit organizations.
It seems like the non-profit needs to have a Google+ page but once you have that, your non-profit knowledge graph should show up. Example searches that return this information include [kiva], [red cross], [donors choose], [american heart association] and many more.
The data that shows up include:
Number of followers on Google+
Wikipedia description
Logo & Link to Google+
Tax ID Number
Founded Date
Tax Deductibility Code
Nonprofit Category
Assets
Revenue
Income
Founders

I spotted this by way of Gregor J. Rothfuss, a technical lead for the Google Maps UI team on Google+.
