Executive summary

The public sources provided do not include a clear, line‑item dollar total for Stephen Siller Tunnel To Towers Foundation’s most recent IRS Form 990 administrative and fundraising expenses in the snippets available; ProPublica and other aggregators host the full Form 990 where those numbers are reported, and the IRS instructions explain which lines and schedules contain administrative and fundraising expense figures [1] [2] [3] [4]. The Foundation’s own site emphasizes “minimal” overhead but does not supply the precise 990 line totals in the excerpts provided here [5].

1. What the question actually asks and where those numbers live on the 990

The user’s question seeks the specific administrative and fundraising expense totals the Foundation reported on its latest IRS Form 990, which are disclosed on Form 990 Part IX (Statement of Functional Expenses) and summarized in Part I/Part VIII depending on filing format, with professional fundraising fees and event-related fundraising captured on Schedule G if above reporting thresholds (IRS instructions clarify Part IX, Part VIII and Schedule G reporting mechanics) [3] [6] [7] [4].

2. What the provided reporting shows (and what it does not)

ProPublica’s Nonprofit Explorer hosts summary data and full Form 990 PDFs for the Tunnel to Towers Foundation and references the 2024 tax filing, but the snippets supplied here do not include the extracted dollar amounts for administrative and fundraising expenses—only that the database contains the full filings and summary data for researchers to inspect [1] [2]. Instrumentl’s summary highlights large grant totals for 2024 but in the supplied excerpt focuses on grants rather than overhead line items [8]. The Foundation’s own financial page reiterates a low‑overhead claim without publishing the specific line‑item totals in the excerpts provided [5]. Charity Navigator and CharityWatch explain how they calculate program vs. overhead ratios from Form 990 data and look for compliance indicators, but the snippets do not quote the Foundation’s exact administrative or fundraising expense totals [9] [10].

3. How to reconcile inconsistent claims and where to find the exact numbers

Because the exact numeric totals are functions of how the organization classifies expenses on Part IX and related schedules (for example, professional fundraising fees reported on Part IX, line 11e, and event expenses on Schedule G), the authoritative way to answer the question is to read the Foundation’s most recent complete Form 990 PDF—available via ProPublica’s Nonprofit Explorer (which links IRS‑processed Form 990 documents) or directly from the Foundation’s filings if posted online [1] [2] [5]. The IRS instructions and Schedule G guidance spell out which lines capture professional fundraising fees and direct fundraising costs, so any apparent discrepancy between the Foundation’s “low overhead” claim and third‑party ratios should be checked against those specific lines [3] [4] [6].

4. Alternative viewpoints, hidden agendas and limitations of the available excerpts

The Foundation’s public messaging stresses minimal overhead, a fundraising‑friendly frame that appeals to donors [5], while watchdog services like Charity Navigator and CharityWatch base their assessments on the Form 990 and may present program‑expense ratios or fundraising efficiency metrics that temper nonprofit marketing claims [9] [10]. The excerpts here do not include the actual Form 990 Part IX totals, so asserting a precise dollar figure would exceed what the supplied reporting supports; instead, investigators must consult the full filing (ProPublica) or the IRS original to extract the administrative and fundraising expense dollar amounts [1] [2].

5. Bottom line and practical next step for verification

The available sources confirm where and how administrative and fundraising expenses are reported on the Form 990 and point to the Foundation’s 2024 filing as hosted by ProPublica, but the provided snippets do not contain explicit dollar totals for those expense categories—therefore the only definitive next step is to open the Foundation’s full 2024 Form 990 (Part IX and Schedule G) via ProPublica’s Nonprofit Explorer or the IRS document to read the reported administrative and fundraising expense figures directly [1] [2] [4].
