A 501(c)(3) Is a Tax Status. It Is Not a Business Model.

Last week, on April 29, during an SSIR webinar on the collapse of grassroots giving, a practitioner who has spent forty years in nonprofit fundraising said something that deserves to be posted in every development organization boardroom in the sector.

A 501(c)(3) is a tax status. It is not a business model.

Mark Dobosz, Vice President of Philanthropy at Mozaic Senior Life and author of the Spring 2026 Stanford Social Innovation Review feature Beyond the Mega-Gift, said it in response to a question I submitted during the Q&A. The line wasn't new to him; he said he had been saying it for years. What the question did, in his words, was sharpen it in real time.

The line matters because it names something the sector has been carefully avoiding.

The numbers behind the crisis

Dobosz’s SSIR article, Beyond the Mega-Gift, opens with a paradox. Total charitable giving in the United States reached a record $592.5 billion in 2024. And yet for five consecutive years, the number of Americans giving to charity has declined. Two-thirds of American households donated in 2000. Today, the figure is roughly half, a loss of approximately 20 million giving households. Just 3 percent of donors now provide 78 percent of all charitable dollars.

His diagnosis of why this is happening is methodical: tax policy changes that eliminated itemization benefits for 9 in 10 taxpayers, eroding institutional trust, economic pressure on middle-class discretionary income, the collapse of the relational networks – religious institutions, civic associations – that historically sustained giving culture, and younger donors migrating to crowdfunding and peer-to-peer mechanisms that bypass sustained organizational relationships entirely. The donor retention rate as of 2025 stands at 31.9 percent. Eighty percent of first-time donors never give again.

These are the metrics of a sector experiencing a structural failure, not just a temporary correction.

The right diagnosis, the wrong prescription

Dobosz offers seven strategies for reversing the decline: monthly giving as the default, mid-level donor cultivation, peer-to-peer fundraising, AI-augmented relationship building, radical transparency, donor-advised fund facilitation, and collective giving partnerships. They are serious, evidence-backed, and worth implementing.

They are also optimization strategies for a model under structural stress.

That’s not a criticism of Dobosz’s work, but more a clarification of scope. His seven strategies answer a real and important question: how do organizations that rely on philanthropic revenue retain more of their existing donors and attract more of those they’ve lost? That question deserves the careful answer he gives it.

The question I submitted during the webinar – and the one I have been building Beyond Grants around – is upstream of those tactics.

If 20 million households have left and retention stands at 31.9 percent, the real problem is that organizations are still running a fundraising-dependent model in an environment where the structural conditions that sustained it have deteriorated and continue to deteriorate. Optimizing the donor relationship strategy does not change architecture; it only improves performance in a fragile system while leaving it intact.

The structural answer lies not with donors but in reducing your need for them.

Two halves of the same argument

After the webinar, I reached out to Dobosz directly on LinkedIn. He promptly replied:  “Your framework for what comes next and my argument about the donor relationship crisis are two halves of the same argument.”

I think he is right. His half-names are collapsing, showing how deep it runs. The Beyond Grants half names what must replace it: earned revenue, profit-based corporate partnerships, blended finance structures, and investment vehicles that offer stakeholders a financial relationship rather than a philanthropic one.

Neither half is sufficient without the other. A sector that understands the collapse but has no structural alternative to propose will continue to optimize the fundraising model long after it has stopped working. A sector that argues for revenue diversification without understanding the depth of the philanthropic crisis it seeks to address will fail to convey the urgency of the structural transformation required.

The line Dobosz delivered in that Q&A: “a 501(c)(3) is a tax status, not a business model,” names what the sector has been careful not to say out loud. The dependency crisis is what you get when you confuse the two long enough.

If you think you can operate 100 percent on philanthropic dollars indefinitely, you are on borrowed time. The data confirms it, quarter by quarter.

Mark Dobosz agreed to be interviewed on the Beyond Grants Podcast. The conversation goes deeper into both halves of the argument.
