California Ranks Last in U.S. Philanthropy Index as Regulatory Burdens Weigh on Nonprofits

California ranks as the most restrictive state in the nation for charitable giving and nonprofit activity, according to a 50-state index published by Philanthropy Roundtable. The state placed last overall with a score of 2.73 out of 10, dragged down by compliance costs, mandatory reporting hurdles, and strict regulatory frameworks. On donor confidence—a measure assessing state tax treatment, donor privacy rights, and legal protections for donor intent—California recorded a score of 0.88, the lowest in the nation by a wide margin.

The findings illustrate a sharp divergence between wealth creation and philanthropic freedom in the U.S. California is home to 246 billionaires, the highest concentration of any state according to an April report by Oxfam. However, the regulatory burden imposed by the state’s legal environment contrasts with lower-density jurisdictions in the Mountain West. Montana earned the top ranking on the index with a score of 8 out of 10, citing low regulatory barriers, favorable economic policies, and robust donor protections.

The index reveals a geographic split in nonprofit activity relative to state economies. The top five states on the list—Montana, Wyoming, South Dakota, Iowa, and Indiana—are predominantly rural and boast 122 charities per billion dollars of gross domestic product. In contrast, the bottom five states—California, New Jersey, Washington, Connecticut, and Illinois—are large, wealthy coastal hubs (with the exception of Illinois) that average 63 charities per billion dollars of GDP.

Report authors Matthew Mitchell and Jack Salmon noted that “large coastal states tend to score worse on the index while Mountain West states tend to score better.”

“This underscores the point that freedom in the philanthropic sphere is not a mere abstraction,” the authors wrote. “These trends demonstrate that more charity freedom and stronger incentives for philanthropy are associated with more philanthropic activity, having a positive impact on the way we live, work, and care for one another in communities across the country.”

Under California’s legal framework, administered in part under the state’s Supervision of Trustees and Fundraisers for Charitable Purposes Act through the Attorney General’s Registry of Charities and Fundraisers, nonprofits face continuous financial administrative requirements. Organizations must register before soliciting public funds, undergo mandatory external financial audits once annual revenue exceeds $2 million, and pay recurring administrative fees, including an annual reporting fee of up to $1,200 and a $500 paid-solicitor fee. California provides no general sales tax exemption for charitable institutions and provides no statutory standing for donors seeking to enforce original gift intent, leaving restricted gifts and institutional endowments under what the report details as “very weak” protections.

Brittnie Panetta, a California-based attorney who cofounded and helped operate a nonprofit for over a decade, noted that “California has a large charitable regulatory structure, and the administrative burden can be significant for smaller nonprofits.”

“Everything from registration, annual reporting, and ongoing compliance needs resources that many startups don’t have quite yet,” Panetta said. She noted that while enterprise-scale organizations maintain dedicated legal and accounting teams to absorb compliance overhead, smaller charities struggle, warning that “compliance costs can divert funds from their mission [and] discourage new organizations from forming.”

Panetta added that administrative requirements scale unevenly across organizational sizes. “Each additional filing or reporting requirement is going to be exponentially more expensive for smaller nonprofits, as they rely on volunteers and limited staff,” Panetta said. “So while the regulatory structure seems the same, the practical impact is not, by any means.”

Panetta emphasized that regulatory mechanisms were established to “promote public trust and accountability.”

“Requiring charities to disclose financial information and comply with reporting obligations helps regulators identify fraud and misuse of assets,” she added. “There has to be a balance between preventing abuse and avoiding any unnecessary barriers to charitable giving.”

State regulatory infrastructure has faced operational strains while enforcing compliance. At an August 2025 hearing reported by The Nonprofit Times, state authorities revealed that more than 30,000 nonprofits had been flagged as noncompliant. The state subsequently paused new delinquency designations while upgrading its overloaded online registration portal.

Regulatory conditions have also entered broader debates over state business climates and executive relocation. Texas, which imposes no state personal income tax, ranked 6th on the index—44 positions ahead of California. Chief Executive Officer Elon Musk, who relocated his primary residence and private foundation from California to Texas, addressed the friction associated with large-scale philanthropy on the WTF podcast, remarking that it is “very difficult to give away money well.”

“It’s very easy to give money away to get the appearance of goodness. It is very difficult to give money away for the reality of goodness,” Musk said.

Capital deployments by ultra-high-net-worth donors in California remain substantial despite statutory restrictions. MacKenzie Scott has directed more than $461 million to California public education institutions since 2021, according to EdSource. Nvidia Corp. Chief Executive Officer Jensen Huang and his wife, Lori, contributed $75 million to Vanderbilt University for its San Francisco campus focused on art, architecture, and design. Meta Platforms Inc. Chief Executive Officer Mark Zuckerberg and his wife, Priscilla Chan, have committed over $7 billion through their Redwood City-based Chan Zuckerberg Initiative.
