THE SANDY HILL FOUNDATION
EIN 22-2668774, tax year January 1, 2024 to December 31, 2024. The return the foundation filed, as the IRS published it, with its arithmetic re-done exactly and sealed September 28, 2026.
Listed in the IRS register as SANDY HILL FOUNDATION. The name above is as written on the return; the EIN is the same foundation.
This is the latest return the IRS has published for this foundation. Its tax year ended 21 months ago, so a later one may have been filed since and not yet appear in the public file. The IRS received it on November 14, 2025.
Nothing carried into the next year: the return shows the year’s amount paid within the year.
Every line we re-do agrees with the return as filed.
Keep this record for the foundation, year on year: the Filing Record, the foundation’s own order, cancellable in writing for a full refund until thirty days after the filing deadline.

What the foundation answered on the form
- Part VI-B 4a: did the foundation invest during the year in a manner that would jeopardize its charitable purposes? No
- Part VI-B 4b: did it make any investment in a prior year that could jeopardize its charitable purpose and that had not been removed from jeopardy? No
- Part VI-B 3a: did it hold more than a 2% direct or indirect interest in any business enterprise? No
- Part VI-B 3b: did it have excess business holdings? Not answered (3a is “No”, so the form does not ask 3b. Our note; not part of the seal.)
- Part VI-B 2a: did it have undistributed income for prior years? No
Quoted as filed. These are the foundation’s own answers; this page does not test them.
Nine controls, read from the return.
Each control reads one part of the filed return and states a fact in a fixed vocabulary: agrees, differs, reported, not reported, not applicable, not checked. Whether any of it met a requirement is counsel’s question, not this page’s.
Recomputed each time the page is read; not part of the seal. The seal covers the body above (controls v2, kernel@2026-09-15.1).
This return: 4 agree, 4 reported, 1 not checked.
| Control | Reads | Result | Detail |
|---|---|---|---|
| Minimum investment return | Part IX line 6 against 5% of line 5, prorated for a short year | agrees | Filed $836,651; recomputed $836,651.1; agrees within the form's whole-dollar rounding. |
| Excise tax | Part V line 1 against 1.39% of net investment income | agrees | Filed $27,577; recomputed $27,576.57; agrees within the form's whole-dollar rounding. |
| Distributable amount | Part X line 7 against the form's own chain from line 1 | agrees | Filed $809,074; recomputed $809,074; agrees to the dollar. |
| Payout coverage | Part XI total against Part X line 7 | reported | Qualifying distributions $3,874,435 against a distributable amount of $809,074 (4.79×). |
| Payout deadline | Part XII undistributed income and the date it falls due | reported | Part XII reports $0 undistributed income for the year ended 31 December 2024: nothing carried into the next year, so nothing from this year falls due by 31 December 2025. |
| Holdings tie-out | The corporate-stock schedule against Part II line 10b | agrees | 41 listed holdings sum to Part II line 10b exactly; the largest is 13.8% of total assets. |
| The foundation's own answers | Part VI-B 2a, 3a, 3b, 4a and 4b, each answered | reported | All 4 answered No (3b not asked: 3a is No). |
| Filing timeliness | The e-file timestamp beside the original due date and the extension window, each with its IRC §7503 roll to the next business day | reported | Return timestamped 14 November 2025; the original due date was 15 May 2025; the six-month extension window ended 15 November 2025 (a Saturday, so 17 November 2025 under IRC §7503). Whether an extension was granted is not visible in the e-file; the timestamp is the preparer software's, not the IRS receipt. |
| Year-to-year continuity | This year's opening balances against last year's closing | not checked | Needs the prior year's return; one sealed year cannot check itself. |
A line that differs is the return’s figure beside the recomputed one, as filed and as recomputed. The return may carry a reason this page cannot read: a schedule filed on paper, an election, a later amendment. It is not a finding. The page is not indexed. It is read by whoever holds the link: the person who asked for it, and anyone the foundation sends it to, its preparer first.
Year-to-year continuity needs two filed years on record. The years, below, reads this foundation’s filed returns in order and holds each against the one before.
A payout is owed on last year’s assets, whatever this year’s market does.
Recomputed each time the page is read; not part of the seal. The seal covers the body above (forward v2, kernel@2026-09-15.1). Read against October 8, 2026.
| By | What | Amount | Basis |
|---|---|---|---|
| May 15, 2026 Passed | Excise tax on the year ending 31 December 2025, due with that return by 15 May 2026. That date has passed; the figure for that year is on its own return, not this one. | $27,576 | Projected under the assumptions below |
| December 31, 2026 | Distributable amount for the year ending 31 December 2025, to be paid out | $809,074 | Projected under the assumptions below |
If net noncharitable-use assets fell 20% over the year ending December 31, 2025: what is owed now, nothing from Part XII, is unchanged; the following year’s minimum investment return would be $669,320, $167,330 less than the projection.
The assumptions, the forward kernel proof, and what was refused
- Net noncharitable-use assets for the year ending 31 December 2025 equal this return's Part IX line 5, $16733022; the thirteen-month average is not observable from a filing.
- Net investment income for that year equals this return's, $1983926.
- No recoveries, income tax or deduction next year; the rates stay 5% and 1.39%; a full tax year.
- The fall shown is 20% of net noncharitable-use assets, applied to next year's average only; what is already owed was computed on this year's average and is unchanged.
- Forward kernel proof (the projection’s own, recomputed, not sealed)
b4c13c6b76c0771c…· kernel@2026-09-15.1 · forward v2, controls v2
- A projection under the stated assumptions, from the foundation's own filed figures; not a forecast, not advice.
- The foundation's preparer computes the actual amounts from the year's monthly values; this page states what the last return implies if nothing changes.
- What is already owed was computed on last year's average assets and does not change with this year's market.
One return is one year. The payout is kept across six.
What a foundation leaves undistributed is due by the end of the next tax year, and what it distributes beyond the year’s amount may be applied in the five years after. So what is owed, and what may be set against it, is only readable across the filed years. The IRS publishes those years; this reads them in order, re-adds each Part XII, and holds each year’s opening lines against the year before’s closing lines.

}The seal’s own scope:
- Every figure here is the foundation's own filed return or exact arithmetic on it; nothing is estimated.
- A 990-PF is a year-end snapshot. Prudence is judged at the time of each decision, which a filing cannot show.
- This page neither establishes nor rules out any tax consequence, and no return is prepared or amended here.
- A line that differs is the return's figure beside the recomputed one, as filed and as recomputed. The return may carry a reason this page cannot read: a schedule filed on paper, an election, a later amendment. It is not a finding.
We don’t prepare or file a 990-PF. We read the one the foundation filed, re-do its arithmetic exactly, and seal what it says.
