Foundations in Maryland that accept unsolicited grant requests

146 foundations in Maryland told the IRS on the latest Form 990-PF that giving is not restricted to organizations picked in advance, and each paid at least 5 grants worth $100K or more that year. Together they paid $226.6M. The largest is The Keith Campbell Foundation for the Environment Inc in Bethesda, which paid $19.3M across 389 grants in 2023. The ten biggest account for 44% of the state total, so most of this money sits with a small number of funders. 62 of the 146 file a submission deadline; the rest leave that line blank or point to a website. In a typical one, 14% of the year's grant dollars went to organizations it had not funded before.

The 25 largest by dollars paid have their own page with the application terms as filed, every recipient, and the trustees. The rest are listed here in full. Where a cell says n/a the filing does not carry that figure: a first-time recipient share needs more than one year of grants on record, and the asset figure comes from the IRS business master file, which does not cover every foundation.

Every figure on this page is that foundation's own latest filed year, which is 2022 or later. A foundation is listed because its Form 990-PF says it does not restrict giving to preselected organizations and it paid at least 5 grants totaling $100K or more that year. Latest-year grants and terms per foundation from IRS 990-PF e-file returns; the newest tax year is partial until the IRS finishes releasing it. Grants are de-duplicated on funder, year, recipient and amount, so identical repeat grants collapse into one and totals can run low. Full method.
