Methodology

Comparable organizations were drawn from electronically filed IRS Form 990 returns and matched on sector (NTEE code), budget (a size-adaptive revenue band that tightens as the organization grows), and geography (same-state first, broadening only when too few peers qualify); every organization within the band forms the peer set. To compare fairly across regions and years, peer compensation is normalized to CA cost of living (BEA Regional Price Parities, 2023) and to the subject's filing year (CPI-U). The figure benchmarked is Form 990 Part VII, Section A, columns D + F — reportable pay plus other compensation, benefits, and deferred amounts (column F may include amounts from related organizations) — with the chief executive matched by role. Related-organization amounts (column E) and institutional trustees are excluded. Full methodology: peerbasis.org/methodology.

Sample, role match & sensitivity

Sensitivity — the subject's percentile under alternative compensation definitions:

BasisSubject percentile
Total compensation (D + F), cost-of-living + inflation adjusted — the PeerBasis default31st
Total compensation (D + F), as reported (no adjustments)41st
Reportable pay only (column D), adjusted28th
All sources (D + E + F), adjusted26th

If the percentile moves materially across these definitions, the result is sensitive to methodology choices, and the board should weigh which basis best fits its facts.

Rebuttable presumption of reasonableness · 26 CFR 53.4958-6

Compensation paid by a tax-exempt organization is presumed reasonable — shifting the burden to the IRS — when three requirements are met. This report supplies the comparability data for the second. The board should record the following in its minutes concurrently with its decision:
