For thirteen years I sat on the receiving end of philanthropy, running a nonprofit funded by people and institutions with very different giving machinery behind them. Some checks came from family foundations with letterhead and board minutes. Others came, mysteriously, from funds with names like the Smith Family Charitable Fund at some large financial institution. Law school finally gave me the map of what I was looking at.
The one-paragraph versions
A private foundation is your own charity: a legal entity you create, fund, and control, with its own board (often your family), its own tax filings, and its own rules to follow. Think of the famous family foundations; the structure is the same at any size.
A donor-advised fund (DAF) is an account, not an entity. You give money irrevocably to a sponsoring organization, itself a public charity, often affiliated with a financial institution or a community foundation. You take the tax deduction now, the money is invested, and you retain the right to advise which charities receive grants over time. Legally, “advise” is the load-bearing word: the sponsor owns the money and could refuse your recommendation, though in practice sponsors follow legitimate advice.
Control: the real dividing line
The foundation gives you actual legal control: you hire staff, run programs if you want, set strategy, and put the next generation on the board. The DAF gives you influence over a stream of grants and nothing else; you cannot employ your kids through it, run your own programs, or bind the sponsor.
That difference cuts both ways. Control means responsibility: a foundation board owes the fiduciary duties I covered in the board duties post, and the foundation rules on self-dealing are stricter than anything else in charity law, reaching transactions with family members that would be routine anywhere else. A DAF outsources all of that to the sponsor, which is precisely why it is easier and precisely why some donors find it thin.
Money mechanics: taxes, payout, and costs
- Deduction limits. Gifts to a DAF are gifts to a public charity, which enjoy higher deductibility limits as a percentage of income than gifts to a private foundation. Donors of appreciated assets feel a second difference: public-charity treatment is generally more favorable for certain non-cash gifts. This is the main tax reason DAFs win by default for many donors.
- Payout. A private foundation must distribute roughly five percent of its assets annually for charitable purposes. A DAF account, under current federal law, has no individual payout mandate, a gap that policymakers have debated for years; sponsors impose their own inactivity policies. If you read criticism of DAFs as charitable parking lots, this is the argument.
- Taxes and overhead. Foundations pay a small excise tax on investment income and carry real administrative cost: legal formation, annual tax filings, accounting, board process. DAFs charge administrative and investment fees but require nothing from you but recommendations.
- Privacy. A foundation’s annual return, the Form 990-PF, is public: grants, assets, trustee compensation, everything. DAF grants can be made anonymously. For some families that is a feature; for transparency advocates it is the other standing criticism.
Which one fits
The pattern advisors converge on: the DAF is the default for straightforward grantmaking, especially below the asset level where a foundation’s fixed costs make sense, and for donors who want simplicity or anonymity. The foundation earns its overhead when the donor wants an institution: staff, direct programs, multigenerational governance, a public identity, or grantmaking too ambitious or unconventional for a sponsor’s policies. And the two are not rivals in practice; plenty of families run both, using the foundation as the institution and a DAF for flexibility.
From the grantee’s side of the table, I will add the thing the comparison charts omit: the vehicle shapes the relationship. Foundation money usually arrives with people attached, board members you can talk to, program officers who visit. DAF money often arrives as a check with no phone number. A donor choosing a structure is also choosing how present they intend to be, and nonprofits can tell.
For how the receiving organizations are classified and governed, see the public charity and board fiduciary duties posts. To research any foundation’s actual giving, its public filings are readable once you know the map, which is the subject of the Form 990 post.
