Before You Start: Is a Private Foundation Actually the Right Vehicle?
A private foundation is a 501(c)(3) charitable organization funded by a single source — usually one donor, one family, or one company. It gives you long-term control over grantmaking, lets you build a charitable legacy across generations, and creates a dedicated legal entity for your philanthropy.
It also comes with ongoing costs most people underestimate. A private foundation must file Form 990-PF every year, pay a 1.39% excise tax on net investment income, distribute at least 5% of its assets annually, and follow strict rules about who it can grant to and who it can transact with. Most foundations don't start to pencil out economically below roughly $1 million in assets, and many advisors set the floor closer to $3 million to $5 million.
If you're starting with less — or if you don't want the administrative burden — a donor-advised fund (DAF) will usually serve you better. A DAF gives you an immediate charitable deduction, no annual filing obligation, and no operational overhead. You give up perpetual family control and the ability to hire family members, but for most donors those trade-offs are worth it.
The people for whom a private foundation genuinely makes sense usually want one or more of the following: permanent family involvement in philanthropy, the ability to operate programs directly (not just grant to other charities), flexibility to fund non-501(c)(3) entities through expenditure responsibility, or a dedicated vehicle large enough to justify its own staff. If that sounds like you, here's how to actually set one up.
Step 1: Choose a Legal Structure — Corporation or Trust
Private foundations can be formed as either nonprofit corporations or charitable trusts. The choice affects governance, flexibility, and the level of court oversight.
Nonprofit corporation. Most modern private foundations are formed as nonprofit corporations under state law. You file Articles of Incorporation with the Secretary of State, adopt Bylaws, and operate with a Board of Directors. Corporations are governed by state nonprofit corporation statutes, which are well-developed and offer clear rules about board fiduciary duties, amendments, and dissolution. You can amend your governing documents through a board vote. Liability protection for directors is generally stronger.
Charitable trust. Trust-form foundations are created by executing a trust instrument — a private legal document, not a state filing — and funding it with an initial contribution. The trust is governed by Trustees who owe heightened fiduciary duties under state trust law, often enforced by the state Attorney General. Changes to the trust instrument typically require court approval. Trust-form foundations are most common when the foundation is created under a will or revocable trust at the donor's death, and when the donor wants to lock in specific charitable purposes that future trustees cannot alter.
For most living donors forming a foundation today, a nonprofit corporation is the better default. It's easier to govern, easier to amend, and fits more cleanly with state charitable registration regimes. Trusts still make sense in estate planning contexts and when the donor wants maximum protection against future mission drift.
Step 2: Incorporate in Your State
If you're forming a corporation, the mechanics look a lot like starting any public charity — with a few foundation-specific details.
You'll file Articles of Incorporation with your state's Secretary of State or equivalent agency. The filing itself is usually straightforward and costs between $30 and $125 depending on the state. But the content of the Articles matters enormously for your IRS application.
Your Articles must include:
- A charitable purpose clause that tracks IRC §501(c)(3) language exactly ("organized and operated exclusively for charitable, religious, educational... purposes within the meaning of section 501(c)(3) of the Internal Revenue Code")
- A dissolution clause directing remaining assets to another 501(c)(3) on dissolution
- Private foundation-specific language committing the organization to comply with the distribution requirement (§4942), self-dealing rules (§4941), excess business holdings (§4943), jeopardizing investments (§4944), and taxable expenditure rules (§4945)
That last bullet is the part most founders miss. The IRS requires private foundations to include specific language accepting the excise tax regime — not because the rules don't already apply, but because the IRS wants it embedded in your governing documents. Missing this language is the most common reason foundation 1023 applications come back for correction.
The state filing is also where you choose your foundation's name, set your registered agent, and list your initial directors. Delaware and Wyoming are sometimes suggested for foundations, but for most donors the right answer is to form in the state where you and your board actually live. You'll need to register in that state anyway for charitable solicitation purposes.
Step 3: Apply for Federal Tax Exemption — Form 1023
Every private foundation must file Form 1023 with the IRS to be recognized as a 501(c)(3). Private foundations cannot use the streamlined Form 1023-EZ — that shorter application is only available to smaller public charities.
The full Form 1023 is long. Expect 25 to 40 pages of narrative, financial projections, budgets, and attached governing documents. For a private foundation you'll specifically address:
- Schedule H if you plan to make grants to individuals (scholarships, hardship grants, emergency relief)
- Foundation classification request — you'll affirmatively classify as a private foundation or, less commonly, as a private operating foundation
- Compensation arrangements with directors, officers, or family members — these must be reasonable and disclosed in detail
- Planned grantmaking — who you intend to fund, how you'll evaluate grants, whether you'll fund individuals or only organizations
The IRS filing fee is $600. Processing times vary, but foundations should plan for 3 to 9 months from submission to determination. Your exempt status is retroactive to the date of incorporation if you file within 27 months of formation.
One detail worth knowing: unlike public charities, private foundations cannot "operate on a good-faith basis" while the 1023 is pending. You can exist and receive contributions, but most practitioners recommend holding off on actual grantmaking until the determination letter arrives. If you need to fund work urgently, a fiscal sponsorship arrangement can bridge the gap.
Step 4: Build the Operational Infrastructure
Getting your determination letter isn't the finish line — it's the starting line. Before the foundation is actually operational, you need:
An EIN. File Form SS-4 with the IRS (free, online, takes ten minutes). You'll need this before opening a bank account.
A bank account. Open a dedicated foundation account. Do not commingle foundation funds with personal or family accounts — this is how self-dealing problems start.
Initial funding. Transfer the assets that will fund the foundation. If you're contributing appreciated securities, coordinate with your tax advisor on the timing — contributions typically qualify for a deduction at fair market value, subject to AGI limits (30% for cash, 20% for appreciated securities contributed to a private foundation).
An investment policy statement (IPS). Your board has a fiduciary duty to prudently manage foundation assets. A written IPS documents the board's asset allocation, risk tolerance, spending policy, and manager selection process. It's also the first thing a regulator asks for if anything ever goes wrong. UPIA (the Uniform Prudent Investor Act) governs investment decisions in most states.
Core governance policies. At minimum: a conflict of interest policy, a document retention policy, a whistleblower policy, a compensation review process, and a grantmaking policy. The IRS doesn't require all of these by statute, but Form 990-PF asks whether you have them, and the absence of a conflict of interest policy in particular is a red flag.
State charitable registration. Most states require foundations to register before soliciting contributions or, in some states, before operating at all. Even foundations that don't solicit publicly may need to file initial registration in their state of formation.
Step 5: Plan for the First Year of Compliance
Your foundation's first Form 990-PF is due four months and 15 days after the end of your first tax year. If you form mid-year, you can elect a short first year to simplify accounting. The 990-PF is public — anyone can look up your foundation's grants, compensation, and investments on ProPublica or GuideStar once it's filed.
You'll also need to think early about:
- How you'll meet the 5% annual distribution requirement (and whether you need to ramp up grantmaking in year one)
- How you'll document grants to verify public charity status of grantees
- Whether any planned transactions could trigger self-dealing concerns (family employment, office space leases, asset sales)
- How you'll track investment income for the 1.39% excise tax

Realistic Cost and Timeline
Here's what starting a private foundation actually costs if you're doing it right:
- State incorporation: $30–$125
- IRS Form 1023 filing fee: $600
- Legal fees for attorney-drafted documents: $3,000–$10,000 (many donors use fixed-fee advisors instead — we charge $7,500 for our Foundation Transition Navigator when the work includes operational setup and board onboarding)
- Registered agent (if applicable): $100–$300/year
- Initial state charitable registration: $0–$500 depending on state
- Annual operating costs once running: $5,000–$30,000+ depending on complexity, plus investment management fees
Timeline from first conversation to first grant is typically 6 to 12 months. Incorporation takes 1–4 weeks, Form 1023 preparation takes 4–8 weeks if you're organized, and IRS processing takes 3–9 months. Operational setup (bank, IPS, policies) can happen in parallel with the IRS wait.
When to Get Help
Starting a private foundation is not the kind of thing most families should do entirely on their own. The IRS application is detailed, the governing document language is specific, and mistakes at formation can create compliance problems that persist for years.
You don't necessarily need a tax attorney, though — and for most straightforward foundations, you shouldn't pay for one. What you need is someone who has done this enough times to know the traps, can draft the right documents, and can help you set up the operational backbone before the checks start going out.
That's what Wylie Advisory does. We handle foundation formation and transition as a flat-fee engagement: governing documents, Form 1023, policies, investment policy statement, and board onboarding — all delivered as a coherent package so you're not stitching together a dozen professionals. If you're further along and just want help thinking through the structure choice or operational setup, our foundation advisory calls are $275/hour with no minimum commitment.
Starting a foundation should feel like the beginning of a long philanthropic project, not a compliance gauntlet. If you get the formation right, the rest is just execution.
