Estimate from itemized IRS Form 990 and 990-PF grant lists. Only foundations with at least 20 grants in each of the last three years (and 20 distinct grantees in the latest), a filing from the last 2 years, and first grants averaging at least $1K are ranked; grants to individuals are left out, and recipient names are matched across years, so a renamed grantee can look new.

Questions about foundations in Idaho
What are the largest foundations in Idaho?
By grants reported on their latest 990s, the largest are Holland M Ware Charitable Foundation ($55.4M across 56 grants), Ja & Kathryn Albertson Foundation Inc ($27.6M) and Islands Fund ($16.2M). Together the top 10 account for 58% of the $265.4M given by the 274 grantmakers in Idaho that made at least 5 grants. Organizations that reported large giving in fewer grants, usually a single transfer to an affiliated charity, are left out of the ranking.
How big is a typical foundation grant in Idaho?
The typical grant is about $15K (the median of each grantmaker's average grant). Half of these grantmakers gave less than $66K in total in their latest filing year, so many are small foundations that give to a few organizations they already know. The largest funders make many more grants, but also get the most requests.
Are there community foundations in Idaho?
Yes. We found 3 community foundations in Idaho with grant activity. The largest by giving are Idaho Community Foundation Inc, Frank a Morbeck Community Foundation and Latah County Community Foundation. Community foundations pool gifts from many local donors and usually run open grant rounds for nonprofits in their area, which makes them a good first stop for local funding.
How do I find Idaho foundations that accept unsolicited proposals?
Most private foundations don't run an open application. Their 990-PF says whether they only give to preselected charities, and their past grants show who they actually fund. Start with the funders above whose grant counts and typical grant size fit your budget, then check each profile's grant history for organizations like yours before you reach out. Read the grant prospecting guide.
