Private Foundation Setup Guide

Not legal or tax advice — private foundation design depends on your specific assets, family structure, charitable goals, and state law. Use this as a framework before talking to a specialist.

What a private foundation is — and why HNW donors use it

A private foundation is an independent legal entity — typically a nonprofit corporation or charitable trust — that you fund, control, and use to pursue your charitable mission indefinitely. Unlike a Donor-Advised Fund, where Fidelity Charitable or Vanguard Charitable holds legal title to the assets, a private foundation is yours. You (and your family) sit on the board, direct grants, set investment policy, hire staff, and define the mission.

Foundations are used for three overlapping reasons:

1. Perpetual charitable legacy. A foundation can operate in perpetuity — decades or centuries past the founder's life. A family DAF account at Fidelity Charitable will eventually be liquidated or converted to a named endowment at the sponsor's discretion; a foundation can legally exist forever.
2. Family governance structure. Appointing children and grandchildren to the board — with a real grant-making process, investment committee, and annual meeting — is a family governance tool with no equivalent in a DAF. Foundations have funded multi-generational engagement strategies at families with $10M+ in charitable assets.
3. Mission specificity. A foundation can directly fund its own programs, hire staff, and own facilities — not just make grants. A "private operating foundation" (hospitals, research institutes, scholarship programs) runs its own charitable activities. A standard "non-operating" foundation makes grants to other organizations.

The size threshold: when does a private foundation make sense?

There is no legal minimum capitalization for a private foundation. In practice, the economics look like this:

• Under $1M: A DAF almost always wins. Foundation overhead — legal, accounting, Form 990-PF preparation, investment management, state compliance — typically runs $5,000–$15,000/year at minimum. On a $500K corpus, that's 1–3% of assets in administration before any giving happens.
• $1M–$5M: Gray zone. A DAF is simpler, cheaper, and more flexible. Some families choose a foundation here specifically for governance goals, knowing they're paying a premium for the control and family engagement.
• $5M–$25M: Private foundation becomes increasingly cost-competitive with a DAF. At $5M earning 6%, the 5% distribution requirement is $250K/year — a real grant program, not a checkbook.
• $25M+: Foundation's structural advantages (perpetuity, identity, mission control, operating programs) generally outweigh a DAF's simplicity. Many families at this level run both — a foundation for the flagship mission and a DAF for tactical giving flexibility.

Operating vs non-operating foundations

Most families set up a non-operating private foundation, which makes grants to other organizations. A private operating foundation directly conducts charitable programs (runs a museum, scholarship fund, or research institute). Operating foundations have different distribution rules and can qualify for the higher 60% AGI deduction limit for contributors — but they require substantially more infrastructure. Unless you're building a program-delivery organization, assume non-operating.

Setup process

1. Incorporate in your state (or use a charitable trust). Most foundations use a nonprofit corporation (Articles of Incorporation + bylaws). A charitable trust is an alternative — simpler to form, but harder to modify and less suitable for multi-generational governance. Your estate attorney files the state paperwork and creates the governing document with the required private foundation provisions under IRS Publication 557.
2. Apply to the IRS on Form 1023. File Form 1023 (Application for Recognition of Exemption Under Section 501(c)(3)) electronically via Pay.gov. If filed within 27 months of incorporation, recognition is retroactive to the formation date.¹ Processing typically takes 3–6 months; the foundation can operate in the meantime, but donors shouldn't claim deductions until exemption is confirmed.
3. Fund the foundation. Initial funding is typically cash, publicly traded stock, or both. More complex assets (closely held business interests, real estate, partnership interests) can be contributed but require qualified appraisals and carry additional scrutiny.
4. Establish governance. Board composition, grant approval process, investment policy statement, conflict-of-interest policy, and document retention policy are all required or strongly advisable elements.

Annual compliance: the three non-negotiables

1. The 5% distribution requirement (IRC §4942)

Every non-operating private foundation must distribute at least 5% of its "net investment assets" each year as "qualifying distributions."² The calculation is based on the average fair market value of investment assets over the year — not on investment returns. If your foundation holds $5M in a down year where it earned 3%, you still owe $250,000 in qualifying distributions.

What counts as a qualifying distribution:

• Grants to public charities and other qualified organizations
• Reasonable and necessary administrative expenses (legal, accounting, staff)
• Program-related investments (low-interest loans to nonprofits for charitable purposes)

What doesn't count: Grants to non-operating private foundations (unless they redistribute within the year), most investment expenses, excise taxes paid.

Penalty for missing the 5% requirement: A 30% excise tax on the undistributed shortfall, escalating to 100% if not corrected after IRS notice.² In practice, advisors model the payout requirement quarterly and accelerate grants or eligible expenses before year-end to avoid falling short.

2. The 1.39% excise tax on net investment income (IRC §4940)

Private foundations pay a flat 1.39% excise tax on net investment income — interest, dividends, rents, royalties, and capital gains realized within the foundation.³ This replaced the prior tiered 1%/2% structure effective for tax years beginning after December 20, 2019. The tax is reported on Form 990-PF and is subject to estimated tax payments.

On a $10M foundation earning 6% ($600K/year in investment income), the annual excise tax is approximately $8,340. This is not a reason to avoid a foundation, but it does need to be factored into the cost comparison with a DAF (which pays no such tax).

3. Form 990-PF — the annual information return

Every private foundation files Form 990-PF annually with the IRS, regardless of size.¹ The return is public record — anyone can look up your foundation's assets, grants, investment returns, and compensation paid to officers. This transparency is intentional and unavoidable. Key components of the 990-PF:

• Part I: Revenue and expenses (investment income, grants made, operating costs)
• Part II: Balance sheet (assets, liabilities, net assets)
• Part VIII: Officers, directors, and compensation
• Part XV: Grants and contributions paid (each grant listed individually)
• Part XVI-A: Excise taxes under Chapter 42 (self-dealing, minimum distribution, etc.)

Form 990-PF preparation typically costs $3,000–$10,000+ annually for a CPA firm experienced with private foundations. This is not optional and is not analogous to a simple personal return.

Self-dealing rules — the compliance trap (IRC §4941)

Self-dealing prohibitions are the most frequently violated private foundation rules and carry the steepest excise taxes. IRC §4941 prohibits certain transactions between the foundation and "disqualified persons."⁴

Who is a disqualified person?

• Substantial contributors (those who contributed more than $5,000 and more than 2% of total contributions)
• Foundation managers (officers, directors, trustees)
• Owners of 20%+ of a corporation, partnership, or trust that is a substantial contributor
• Family members of any of the above (spouse, ancestors, descendants, spouses of descendants)
• A corporation, partnership, or trust in which disqualified persons collectively own 35%+ of the voting power

Prohibited transactions include:

• Selling, exchanging, or leasing property between the foundation and a disqualified person
• Lending money (even at fair market rates) between the foundation and a disqualified person
• Furnishing goods, services, or facilities — with narrow exceptions for reasonable compensation for necessary services
• Paying compensation that is not reasonable and necessary for services actually rendered
• Transferring foundation assets to a disqualified person or allowing a disqualified person to use foundation assets

One legitimate exception: family members can serve as officers and receive reasonable compensation for services actually rendered. Defining "reasonable" requires contemporaneous documentation and, for large foundations, independent compensation studies.

Other excise taxes to know

Excess business holdings (IRC §4943): The foundation and its disqualified persons together cannot own more than 20% of a business enterprise (35% if no other single person controls more than 15%). This matters when founding a family business owner transfers business interests to a foundation — there's a 5-year window to divest to permitted levels, but it requires planning in advance.

Jeopardizing investments (IRC §4944): Foundation managers cannot make investments that jeopardize the foundation's charitable purpose. Historically this restricted speculative investments (options, futures, etc.), though the IRS has become more flexible as investment products have evolved. High-risk venture positions require documented board justification and investment policy coverage.

Taxable expenditures (IRC §4945): Foundations cannot make grants for voter registration, lobbying, or grants to individuals without an IRS-approved selection procedure. International grants require additional documentation and expenditure responsibility procedures.

Contribution deduction limits — lower than a DAF

Contributions to a non-operating private foundation carry lower AGI deduction limits than contributions to public charities or DAFs:⁵

Note: For appreciated property other than publicly traded securities, the foundation deduction is typically limited to cost basis, not fair market value — a significant disadvantage compared to a DAF contribution. Starting in 2026, the OBBBA's 0.5% AGI floor applies to all itemized charitable deductions, and a 35% AGI cap limits total deductible contributions for high earners.⁶ Unused contributions carry forward for 5 years.

Private Foundation vs DAF — decision table

Foundation + DAF in combination

Many HNW families with foundations also maintain a DAF account. The combination works well:

• Use the foundation for the flagship family mission, formal governance, and perpetual legacy grants.
• Use the DAF for tactical giving — appreciated stock contributions in high-income years (60% AGI limit vs 30%), anonymous grants, supporting organizations your foundation can't easily reach, or giving while the family decides where to direct foundation grants.

The foundation board can even direct grants to the family's DAF account, treating the DAF as a distribution conduit — though IRS rules require the foundation to track that distributions actually reach qualified charities within the year.

OBBBA estate context

With the One Big Beautiful Bill Act permanently setting the estate and gift tax exemption at $15M per person ($30M for married couples),⁶ the estate-planning rationale for foundations has shifted. For families under $30M combined, the foundation decision is now primarily about charitable mission and family governance, not estate tax reduction. For families over $30M, a foundation remains a tool in the broader estate plan — but CLTs, GRATs, and dynasty trusts now compete for that role alongside foundations.

Common mistakes

• Underfunding and missing the 5% payout. The 5% distribution is calculated on asset fair market value — not on realized income. A foundation that's mostly in long-term appreciated stock with low yield can struggle to meet the payout requirement without liquidating positions. Model the payout obligation before choosing an investment strategy.
• Self-dealing by family board members. Even well-intentioned transactions — a family member's company providing IT services at "cost," renting office space in a family building — can be prohibited self-dealing. Have every family-adjacent transaction reviewed by counsel before it occurs, not after.
• Paying compensation to family directors without documentation. Compensation to disqualified persons requires extensive documentation, comparison data, and independent board approval. Informal arrangements almost always fail scrutiny.
• Granting to a family member's scholarship fund without IRS approval. Individual grants require a prior IRS-approved procedure (Form 4945) for each scholarship or fellowship program. Many foundations skip this and end up paying taxable expenditure penalties.
• Choosing a foundation when the real goal is a DAF. If the primary goals are a charitable deduction, appreciated stock contribution, and simple annual giving — a DAF is almost always easier, cheaper, and more flexible. A foundation is the right answer when you genuinely need control, perpetual governance, or operating programs. Don't pay the compliance premium for a benefit you don't actually need.
• Not planning for termination. Terminating a private foundation requires distributing all assets to qualified public charities — and if done incorrectly, can trigger a significant termination tax. If the family loses interest in the foundation after one generation, converting to a DAF or distributing to a community foundation is the typical path. Plan this option into the governance documents upfront.

What a specialist does in foundation setup and ongoing management

Private foundation work typically involves three professionals working in coordination:

• Estate attorney: Incorporation, IRS application, governing documents, self-dealing advice, and grant-making procedures. The attorney designs the legal structure and compliance framework.
• CPA: Form 990-PF preparation, excise tax modeling, quarterly payout projections, and ongoing compliance monitoring. The CPA keeps the numbers and the government filings accurate.
• Investment/financial advisor (ideally a charitable planning specialist): Investment policy statement aligned with the 5% payout requirement, tax-efficient asset placement within the foundation (minimizing the 1.39% excise tax on realized gains), complex asset contributions, and the integration of the foundation with the family's broader estate and tax plan. The advisor also typically leads the initial conversation about whether a foundation, DAF, or combination makes sense for the family's goals and resources.
