Private Foundations

What Is a Private Foundation?

A private foundation is a tax-exempt charitable organization created by a single donor, family, or corporation. Unlike a public charity — which raises money broadly from the public — a private foundation is funded primarily by one source and governed by people the founder selects. Most family foundations are organized either as nonprofit corporations or as charitable trusts, each with different governance mechanics that a qualified attorney should explain.

The "private" label matters legally. The IRS treats private foundations as a distinct category subject to a set of rules that do not apply to public charities or to donor-advised funds. Understanding those rules is inseparable from understanding the vehicle itself.

Why Families Create Foundations

Control is the primary draw. A family that establishes a foundation sits on its board, votes on grants, hires staff, sets investment policy, and shapes the institution's identity across generations. That level of authority simply is not available through a donor-advised fund, where the sponsoring organization retains legal control over the assets.

Perpetuity is equally important to many families. A foundation can outlast its founders by generations, becoming a shared family institution — sometimes the single asset that keeps extended family members engaged with one another and with a shared sense of purpose. Families sometimes describe this as building a vehicle for stewardship that transcends any individual's lifetime.

Visibility and identity also matter. A foundation with the family name attached makes grants publicly, receives recognition, and can build relationships with grantee organizations that a private donor acting anonymously cannot. For families navigating how to raise children around wealth, foundation board participation often serves as a structured introduction to responsibility, governance, and financial decision-making.

How Foundations Work: The Basic Structure

A family endows the foundation — contributes cash, securities, or other assets — and the foundation invests that endowment. Each year, a minimum percentage of the foundation's assets must be distributed for charitable purposes; the law sets this percentage, and a qualified CPA should confirm the current requirement. This is called the minimum distribution requirement. Qualifying distributions include grants to operating charities, reasonable administrative expenses, and, in certain cases, program-related investments.

The foundation files an annual public return (Form 990-PF in the United States) that discloses officers, directors, compensation, investments, and every grant made during the year. This is meaningfully different from a donor-advised fund, which requires no public disclosure by the individual donor. Families who value privacy should weigh this carefully.

An excise tax applies to the foundation's net investment income. The rate is set by law and can change; a CPA should be consulted for current figures. The tax is modest relative to the investment returns a well-managed endowment may generate, but it is a real and ongoing cost.

Self-Dealing and Key Prohibitions

Self-dealing rules are among the most important — and most frequently misunderstood — constraints on private foundations. In general, the law prohibits financial transactions between the foundation and "disqualified persons," a category that includes the founders, board members, substantial contributors, and their family members.

Prohibited transactions can include things that might seem innocuous: a foundation leasing office space from a family member, a foundation lending money to a board member, or a foundation purchasing artwork from someone related to the family. Violations can trigger significant excise taxes on both the disqualified person and, in some cases, the foundation managers who approved the transaction. A qualified attorney should map out these rules in detail before the foundation is operational.

Family employment is permitted in defined circumstances — family members may serve as officers or employees and receive reasonable compensation — but the rules around what is "reasonable" and what qualifies are specific, and foundation governance and compliance require ongoing professional oversight. Board seats for family members carry no such compensation restrictions, which is why governance structures are often designed with board and staff roles carefully separated.

Costs and Practical Realities

Private foundations carry both startup and ongoing costs that families should understand before committing. Illustrative startup costs — meaning these are examples meant to convey order of magnitude, not quotes — might range from a few thousand dollars for a simple charitable trust to well over fifty thousand dollars for a foundation with a complex structure, multiple states of operation, or sophisticated investment provisions. Legal and accounting fees at formation can vary significantly based on complexity.

Ongoing annual costs are real. A foundation needs to file its 990-PF, maintain investment accounts, track grants, comply with minimum distribution requirements, and document its governance decisions. Illustrative annual operating budgets for a small family foundation might run from roughly thirty to one hundred thousand dollars or more once legal, accounting, investment management, and any administrative staff costs are included. Larger foundations with dedicated staff run considerably more.

Because of this cost structure, foundations tend to be evaluated most seriously when a family anticipates endowing the vehicle at a meaningful scale — often discussed in the range of several million dollars at a minimum, though the right threshold depends on the family's goals and structure. At lower asset levels, a donor-advised fund often provides comparable tax benefits with far less complexity.

Tax Considerations

Contributions to a private foundation are generally tax-deductible, but the deduction rules differ from those that apply to public charities — often less favorable for certain asset types such as appreciated stock or closely held business interests. The specifics depend on the asset contributed, the donor's overall tax picture, and current law, so a CPA must evaluate any particular situation. The charitable deduction rules are worth understanding before a large gift is made.

Assets inside the foundation grow free of income tax (subject to the excise tax on investment income noted above). The step-up in basis that heirs would otherwise receive does not apply to assets donated to a foundation, so tax planning around the timing and form of contributions matters.

Foundations can own a wide range of investments, but certain holdings — particularly interests in pass-through entities that generate unrelated business taxable income — can create unexpected tax complications. Qualified advisers should review the foundation's investment policy alongside its tax position.

Comparing Alternatives and Common Questions

Families often evaluate foundations alongside donor-advised funds, sometimes concluding that the two vehicles can work together rather than in competition. One approach that may be evaluated is establishing a private foundation as the family's primary grantmaking institution while also maintaining a donor-advised fund for situations where anonymity, speed, or simplicity is preferred. The comparison of giving vehicles explores those trade-offs in depth.

Conversion is also a consideration some families revisit over time. A foundation that has outlived its original purpose, grown too small to justify its costs, or faces governance challenges sometimes distributes its remaining assets to a donor-advised fund — effectively "spinning down" the foundation. The mechanics and tax treatment of such a conversion require professional guidance.

Families considering a foundation should also explore the operational realities of effective grantmaking — the work of identifying grantees, conducting due diligence, and measuring impact is substantive and requires either staff capacity or a willingness to engage deeply as a board.
