To start a family foundation, you choose a legal structure, file organizing documents with your state, get an Employer Identification Number from the IRS, and then apply for tax-exempt status under Section 501(c)(3). From first planning meeting to IRS approval, plan on six months to a year. And plan on the rules that come after approval: nearly every family foundation is classified as a private foundation, which means annual excise taxes, a mandatory yearly payout, and a strict ban on most financial dealings between the foundation and the family that funds it.
Pick a Legal Structure
The first choice is between a nonprofit corporation and a charitable trust. A corporation has a board of directors, officers, and bylaws, and generally offers stronger personal liability protection for the people running it. A trust is governed by a trust agreement and one or more trustees, with less ongoing paperwork but harder amendment rules and exposure to your state’s trust laws.
Most family foundations incorporate. The corporate form makes it easier to add or replace board members as the foundation passes between generations. Whichever form you pick, the organizing document has to contain specific language before the IRS will grant exempt status.
Draft the Organizing Documents
The IRS requires a purpose clause limiting the foundation’s activities to charitable, educational, religious, scientific, or other exempt purposes described in Section 501(c)(3).1Internal Revenue Service. Organizing Documents – Charity It also requires a dissolution clause: if the foundation ever shuts down, its remaining assets have to go to another tax-exempt organization or to a government entity, not back to the family.2Internal Revenue Service. Sample Organizing Documents – Public Charity
List the names and addresses of your initial directors or trustees. Even with a small starting board of two or three family members, assign clear roles (president, secretary, treasurer for a corporation) so nobody wonders who signs what. Before you file, search your state’s business entity database to confirm the name you want is available and distinguishable from existing organizations.
Alongside the organizing document, draft bylaws (for a corporation) or an operating agreement (for a trust). Bylaws set meeting frequency, election of new members, voting, and how conflicts of interest get handled. A written conflict-of-interest policy matters more for a family foundation than for almost any other kind of nonprofit, because the IRS looks hard at transactions between the foundation and its founders, board members, and their relatives.
File With Your State
Filing the articles of incorporation or trust agreement with the appropriate state agency, usually the Secretary of State, is what creates the foundation as a legal entity. Most states offer online filing; mail is still available. Filing fees run from around $50 to several hundred dollars depending on the state. Online filings can be approved in a few business days; paper submissions can take several weeks.
You will need to name a registered agent, meaning a person or service authorized to receive legal notices and official correspondence for the foundation. Once the state approves the filing and issues a certificate of incorporation or stamped trust agreement, the foundation can enter contracts, open bank accounts, and hold property in its own name.
Get an Employer Identification Number
You need an EIN before you can apply for tax-exempt status. It functions as the foundation’s tax ID on every federal filing and financial account.3Internal Revenue Service.

Apply for 501(c)(3) Status
Federal tax-exempt status comes from filing Form 1023 electronically through Pay.gov.5Internal Revenue Service. About Form 1023, Application for Recognition of Exemption Under Section 501(c)(3) of the Internal Revenue Code The application asks for your state-approved organizing documents, a detailed description of planned activities, and financial projections. If the foundation has existed for less than a year, provide projected income and expenses for the current year plus the next two — three years of financial data total.6Internal Revenue Service. Instructions for Form 1023
The user fee is $600 for the full Form 1023 and $275 for the streamlined Form 1023-EZ.7Internal Revenue Service. Form 1023 and 1023-EZ – Amount of User Fee The 1023-EZ is available only to organizations expecting annual gross receipts under $50,000 and total assets under $250,000, so most family foundations, which start with an endowment above that, have to file the full Form 1023.8Internal Revenue Service. Instructions for Form 1023-EZ
Timing and the Determination Letter
The IRS assigns the application to a specialist. If everything is complete, an approval letter may arrive with no further contact; if not, expect a call or letter asking for more information, and respond quickly, because delays extend the timeline. The IRS reports that 80 percent of Form 1023 determinations are issued within about 191 days, roughly six months, though some take longer.9Internal Revenue Service. Where’s My Application for Tax-Exempt Status?
Approval comes as a determination letter recognizing the foundation as exempt from federal income tax and confirming that donations to it are tax-deductible.10Internal Revenue Service. Exempt Organizations Rulings and Determinations Letters Keep the letter permanently. You will need it to open bank accounts, receive grants, and prove your status to donors.
Why Your Foundation Will Be Classified Private
Because a family foundation is funded by a single family rather than broad public support, the IRS classifies it as a private foundation under Section 509(a).11Office of the Law Revision Counsel. 26 USC 509 – Private Foundation Defined That classification is what triggers the excise taxes, distribution requirement, and self-dealing rules that follow.
Hold the First Board Meeting and Open Accounts
Once you have the EIN and the determination letter, hold a formal first board meeting. The board adopts bylaws, approves the conflict-of-interest policy, authorizes bank and investment accounts, and designates who can sign checks or approve transfers. Record minutes. The IRS expects private foundations to keep detailed records of board actions.
Open a dedicated bank account in the foundation’s name using the EIN and the determination letter. Keep it entirely separate from any personal or family account. Mixing foundation funds with personal money, even briefly, can trigger severe tax penalties and threaten exempt status. When the account is open, transfer the initial endowment into the foundation’s name. That transfer is the point at which the foundation actually becomes a working entity.
Before investing any of it, adopt a written investment policy. The policy guides how assets are invested, helps the board meet its fiduciary duty to manage funds prudently, and, in practical terms, helps the foundation earn enough to meet the annual payout requirement described below.
What Ongoing Compliance Looks Like
Running a private foundation is not a one-time setup. Several annual obligations carry real penalties if missed.
Annual Return: Form 990-PF
Every private foundation files Form 990-PF each year, due the 15th day of the fifth month after the end of its fiscal year. For a calendar-year foundation, that means May 15.12Internal Revenue Service. Annual Exempt Organization Return – Due Date You can request an automatic six-month extension with Form 8868 before the original deadline. Late-filing penalties run $25 per day (up to $12,500 or 5 percent of gross receipts, whichever is less) for foundations with annual gross receipts of $1,274,000 or less, and $125 per day (up to $63,500) for larger foundations.
The 5 Percent Payout
Private foundations must distribute at least 5 percent of the fair market value of their non-exempt-use assets each year as qualifying distributions, typically grants to other charities or direct charitable activities.13Internal Revenue Service. Minimum Investment Return Falling short brings an initial excise tax of 30 percent on the undistributed amount, and if the shortfall is still not fixed after the taxable period ends, an additional 100 percent tax on whatever remains.14Office of the Law Revision Counsel. 26 USC 4942 – Taxes on Failure to Distribute Income
Excise Tax on Investment Income
Private foundations owe an annual excise tax of 1.39 percent on net investment income, which includes interest, dividends, rents, royalties, and capital gains.15Office of the Law Revision Counsel. 26 USC 4940 – Excise Tax Based on Investment Income The tax is reported and paid on Form 990-PF.
State Filings
Most states also require nonprofits to file annual reports and, if the foundation solicits from the public, to register with the state’s charitable solicitation office. Fees and requirements vary widely. Check with your state’s Secretary of State and Attorney General to confirm what applies.
Self-Dealing: The Rule Family Foundations Trip Over Most
Unlike public charities, which allow reasonable transactions between the organization and its insiders, private foundations face a near-total ban on financial transactions between the foundation and its “disqualified persons.” This is where family foundations most often run into trouble, so it is worth understanding before the foundation exists rather than after.
Who Is a Disqualified Person
Disqualified persons include the foundation’s substantial contributors (usually the founding family), all foundation managers (directors, trustees, officers), and the family members of each: spouses, ancestors, children, grandchildren, and their spouses.16Internal Revenue Service. Disqualified Persons Corporations, partnerships, and trusts in which those individuals hold more than 35 percent of the voting power, profits interest, or beneficial interest are also disqualified.
What Is Prohibited
Between the foundation and any disqualified person, the following transactions count as self-dealing, whether direct or indirect:17Office of the Law Revision Counsel. 26 USC 4941 – Taxes on Self-Dealing
- Buying, selling, or leasing property. The foundation cannot buy from or sell to a family member, even at fair market value.
- Lending money or extending credit, in either direction, regardless of interest rate.
- Providing goods, services, or facilities. A family member cannot rent office space to the foundation, and the foundation cannot let family members use its property.
- Paying compensation. Reasonable pay for personal services such as legal or accounting work is an exception, but it must be genuinely necessary and not excessive.
- Transferring foundation income or assets for the personal benefit of a disqualified person.
The initial excise tax is 10 percent of the amount involved, imposed on the disqualified person for each year the self-dealing goes uncorrected. A foundation manager who knowingly approves the transaction owes an additional 5 percent (capped at $20,000 per act). If the transaction is not corrected within the taxable period, the tax on the disqualified person jumps to 200 percent of the amount involved, and 50 percent for any manager who refuses to participate in correcting it.17Office of the Law Revision Counsel. 26 USC 4941 – Taxes on Self-Dealing
Separate rules also limit how much of an operating business the foundation and its disqualified persons can own together, which matters if you plan to fund the foundation with closely held business interests.18Internal Revenue Service. Excess Business Holdings of Private Foundation Defined Review those limits before making the contribution, not after.
What Donors Can Actually Deduct
Gifts to a private foundation are deductible at lower limits than gifts to public charities. For cash, you can deduct up to 30 percent of your adjusted gross income in the year of the gift.19Internal Revenue Service. Charitable Contribution Deductions For long-term capital gain property such as appreciated stock, the limit is generally 20 percent of AGI. Cash to public charities, by comparison, is deductible up to 60 percent of AGI. Amounts over the limit carry forward for up to five additional tax years.
Those lower ceilings are one of the trade-offs of running your own foundation. Families whose primary goal is the largest possible deduction with minimal administrative work sometimes use a donor-advised fund instead, which allows cash deductions up to 60 percent of AGI and has no annual filing. A donor-advised fund does not give you the same direct control, the ability to hire staff, or the option to run your own charitable programs, which is where a private foundation earns its complexity.
