Frequently asked questions
Do private foundations accept grant applications?
Many do not. Of the 74,872 foundations listed here, about 76% reported on Form 990-PF that they give only to preselected organizations and do not accept unsolicited requests. Use the "Accepts applications" filter to see the rest, and check each foundation's instructions.
Where does this foundation data come from?
From private foundations' Form 990-PF returns, e-filed with the IRS and published in the IRS Form 990 Series downloads. GrantsJunction keeps each foundation's latest return, its 25 largest grants and its giving by state, and refreshes monthly. Grants to individuals are counted but never named.
How can I find foundations that fund organizations like mine?
Search for a similar organization's name or your cause (for example "food bank" or "rural health"). Results include foundations whose grant lists or purposes mention it. Add your state to see foundations that gave to recipients there.
