Overview
Private foundations are separate 501(c)(3) organizations typically funded by a single family or individual. Unlike public charities or donor-advised funds, private foundations usually make grants to other nonprofits and occasionally operate programs directly. For families considering long-term philanthropy, a private foundation can provide structured grantmaking, tax planning opportunities, and a vehicle for teaching younger generations about stewardship and values (IRS, Private Foundations: https://www.irs.gov/charities-non-profits/private-foundations).
This entry explains how private foundations work, who should consider them, the trade-offs versus alternative vehicles such as donor-advised funds, governance and compliance fundamentals, and practical setup and operational tips drawn from my 15+ years advising families.
Why families choose private foundations
Families establish private foundations for several, often overlapping reasons:
- Control: Founders generally appoint the board and set policies that reflect their philanthropic vision and grantmaking priorities.
- Legacy and education: A foundation formalizes giving across generations and creates forums (board meetings, site visits) to pass on philanthropic values.
- Investment growth: Assets held and invested by the foundation can grow tax-exempt inside the foundation, supporting future grantmaking.
- Tax benefits: Contributions to the foundation are tax-deductible subject to IRS limits and rules; the foundation can also receive noncash gifts like private company stock.
- Strategic grantmaking: Foundations can make multi-year grants, fund program-related investments, and support research or operational capacity-building in ways donors might not when giving directly.
However, these benefits come with administrative, legal, and regulatory responsibilities. I routinely advise clients to weigh these trade-offs against simpler solutions such as donor-advised funds (DAFs) or direct grants.
Key rules and compliance points (what you must know)
- Minimum distribution requirement: Private foundations are subject to an annual minimum distribution requirement (commonly described as roughly 5% of net investment assets), intended to ensure active grantmaking (IRS guidance).
- Annual reporting: Foundations must file Form 990‑PF each year, disclosing finances, grants, and certain transactions.
- Excise tax: Foundations pay an excise tax on net investment income (see IRS page for current percentage). This tax and other rules distinguish foundations from public charities.
- Deduction limits for donors: Donors to private foundations face lower AGI percentage limits for charitable deductions than for gifts to public charities (IRS limits apply to cash and appreciated property).
For the latest numeric thresholds and tax rates, always consult the IRS Private Foundations page and your tax advisor (IRS: https://www.irs.gov/charities-non-profits/private-foundations).
Comparing private foundations to donor-advised funds and public charities
-
Donor-advised funds (DAFs) are quicker and cheaper to set up and offer immediate tax deductions while allowing donors to recommend grants over time. DAFs typically have fewer administrative burdens but less direct control than a private foundation. See our guide When to Use a Donor-Advised Fund vs a Private Foundation for a side‑by‑side comparison: https://finhelp.io/glossary/when-to-use-a-donor-advised-fund-vs-a-private-foundation-choosing-the-right-vehicle/.
-
Public charities often provide programmatic delivery of services and accept broad public support. They have different tax deduction rules and governance profiles.
If you are undecided, a common practical path is to start with a DAF while you build the financial and governance capacity needed for a foundation. Our primer Donor-Advised Funds: A Practical Guide is a useful starting point: https://finhelp.io/glossary/donor-advised-funds-a-practical-guide/.
Is a private foundation right for your family? (feasibility checklist)
Consider these questions before forming a foundation:
- Do you have sufficient seed capital? Foundations are most cost‑effective when funded with a meaningful endowment (commonly several hundred thousand dollars or more) to absorb start-up and ongoing costs.
- Are you prepared for governance and administration? Think board composition, conflicts-of-interest policies, grant review processes, and recordkeeping.
- Do you have a multiyear philanthropic vision or programmatic interest that requires special grant structures (e.g., program-related investments, multi‑year capacity grants)?
- Will you accept noncash and complex gifts (closely held stock, real estate)? Managing and valuing these assets requires specialized expertise.
If any answer is “no,” a DAF or partnering with a community foundation may be a better first step.
Practical setup steps and estimated costs
- Feasibility study: Engage legal and tax counsel to map objectives, initial funding size, and governance needs.
- Legal formation: Draft articles of incorporation and bylaws, apply for 501(c)(3) recognition, and obtain state registrations as required.
- Governance documents: Create a family philanthropy charter, conflict-of-interest policy, grantmaking guidelines, and investment policy statement.
- Initial funding and banking: Seed the endowment and set up accounting systems; consider a separate investment manager with foundation experience.
- Ongoing operations: Budget for annual auditing, tax filings (Form 990‑PF), staff or outsourced foundation management, and program expenses.
Startup costs vary widely. Smaller private foundations can expect tens of thousands in legal and setup fees, while larger, complex foundations will incur proportionately greater expenses. Ongoing administrative costs typically include accounting, auditing, investment management, and grant due diligence.
Governance and family engagement best practices
- Formalize roles: Use written governance documents to define founder privileges, board terms, and succession rules.
- Create a family giving policy: Clarify priorities, grant sizes, reporting expectations, and youth engagement (see Creating a Family Charitable Giving Policy: https://finhelp.io/glossary/charitable-giving-establishing-a-family-philanthropy-charter-governance-and-values/).
- Stagger board transitions to preserve institutional memory and avoid abrupt shifts in grantmaking.
- Use structured learning: Fund site visits and require grantee reports to create a learning culture across generations.
In my practice, foundations that invest in clear governance and regular family education meetings avoid many of the relationship pitfalls that otherwise can undermine long-term impact.
Investment and grantmaking strategies
- Adopt an investment policy that balances spending needs (minimum distribution) with long-term capital preservation.
- Consider program-related investments (PRIs) if you want mission-aligned, below-market returns that recycle capital back into philanthropic efforts.
- Use multi-year grants for capacity building, but include reporting milestones.
- Preserve flexibility by setting aside a discretionary pool for opportunistic grants.
Common mistakes to avoid
- Underestimating administrative burden: Foundations need ongoing compliance and thoughtful oversight.
- Weak conflict-of-interest controls: Families frequently run afoul of self-dealing rules if policies aren’t enforced.
- Treating the foundation as a personal checking account: Private foundations must avoid transactions that provide private benefit to insiders.
- Skipping professional advice: Tax and legal guidance is required, especially for accepting noncash gifts or complex transactions.
Example case (anonymized)
A family I worked with seeded a foundation with $1 million focused on education. They adopted a five‑person board (including two next‑generation members), an investment policy targeting 4–6% annual spending plus inflation, and a yearly family learning convening tied to site visits. Over five years, disciplined granting and professional investment oversight increased the funded grant pipeline while preserving principal for future generations.
Tax and reporting reminders
- File Form 990‑PF annually; maintain detailed grant and expense documentation.
- Understand deduction limits and valuation rules for noncash gifts.
- Monitor excise tax and private benefit/self‑dealing rules; remediate promptly if compliance issues arise.

When to consult professionals
Engage tax counsel, legal counsel, and an investment advisor with foundation experience before forming a foundation. I recommend a staged approach: start with a feasibility study, pilot activities (perhaps via a DAF), and only incorporate the foundation once governance and funding are in place.
Frequently asked questions
Q: How much must a private foundation distribute each year?
A: Foundations are generally subject to a minimum distribution requirement intended to encourage active grantmaking; check IRS guidance and your advisor for the precise calculation.
Q: Can family members be paid by the foundation?
A: Yes, but compensation must be reasonable and arms-length. Strong conflict-of-interest policies and board oversight are essential.
Q: Can a foundation accept donor-advised fund transfers?
A: Yes, DAF grants can be used to fund foundation activities when structured appropriately, but consult counsel on tax and advisory implications.
Conclusion and practical next steps
Private foundations are powerful tools for families that want enduring control over philanthropic dollars, education across generations, and strategic, sophisticated grantmaking. They require disciplined governance, ongoing compliance, and sufficient financial scale to justify the costs. Start with a feasibility study, test intent through simpler vehicles like donor-advised funds, and assemble a team of legal, tax, and investment professionals before committing significant capital.
