Hosts funds for others
MARIN COMMUNITY FOUNDATION administers funds on behalf of other donors. The grants recorded as coming in are contributions into those funds, so they count custody rather than support for a programMARIN COMMUNITY FOUNDATION runs itself. This page therefore states the flows and does not draw the comparisons it would draw for an operating charity: concentration, funder retention, grant dependency and the peer field are all left out, because each of them would read a vehicle as if it were a program.

Payments out run 2.3x the contributions on record, which says the incoming side is incomplete rather than that the vehicle is unusually busy: most donors to a fund like this are individuals, who file no return for us to read.
The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2020 to 2021, from $755M to $1.4B (+88%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 2 of the last 9 reported years ran a deficit.

Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.

Who funds it, year by year
2017 → 2023: the base broadened from 20 funders to 38 funders, grant income fell $58M → $51M.
27 of 110 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 35% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
Left out of every figure on this page: $152M from 8 payers (the payer shares this organization's board, largest McF Gift Fund Inc). These are real filings, and they are not money MARIN COMMUNITY FOUNDATION raised.
From the IRS filings of MARIN COMMUNITY FOUNDATION’s funders (the co-funder graph). Top 30 of 110 funders by total. Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Where its funders are
55% of MARIN COMMUNITY FOUNDATION's grant income comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $151M arriving through sponsors registered in 17 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
