To form a charitable foundation, you incorporate a nonprofit under state law, adopt governing documents that satisfy the IRS, obtain an Employer Identification Number, and file Form 1023 with a $600 user fee to secure 501(c)(3) tax-exempt status. The IRS issues about 80 percent of Form 1023 determinations within 191 days. The choices you make at formation — especially whether your organization will be classified as a private foundation or a public charity — set the tax rules, filing obligations, and restrictions that will govern the organization for as long as it exists.
Decide Whether Yours Will Be a Private Foundation or a Public Charity
Every 501(c)(3) organization falls into one of two categories, and the category is not optional cosmetic labeling. It determines the tax rules that govern operations, the deduction limits that apply to donors, and the level of regulatory scrutiny you will face.1Internal Revenue Service. Determine Your Foundation Classification
A public charity draws support from a broad base of donors, government grants, or program revenue. A private foundation is funded by a small number of sources, often a single individual, family, or corporation. If you are starting a foundation with your own money and plan to control how grants are distributed, you are almost certainly forming a private foundation. That classification triggers a 1.39 percent annual excise tax on investment income, a requirement to distribute at least 5 percent of your assets each year, and the self-dealing rules covered below.
Pick a Name and Define a Qualifying Mission
The foundation’s name must be unique within your state of incorporation. Check your Secretary of State’s business name database before committing to one, and search the U.S. Patent and Trademark Office database to avoid infringing an existing trademark.
Your mission has to fit the IRS’s list of exempt purposes: charitable, religious, educational, scientific, literary, testing for public safety, fostering amateur sports competition, and preventing cruelty to children or animals.2Internal Revenue Service. Exempt Purposes – Internal Revenue Code Section 501(c)(3) “Charitable” is read broadly and covers relieving poverty, advancing education, eliminating discrimination, and combating community deterioration. A mission that doesn’t fit within one of the recognized categories will draw a denial.
Form the Legal Entity
The two common structures are the nonprofit corporation and the charitable trust. A nonprofit corporation is governed by bylaws and a board of directors; a charitable trust is managed by trustees under a trust agreement. Most foundations incorporate because the corporate form offers more governance flexibility and clearer liability protection for the people running it.
To incorporate, you file Articles of Incorporation with your state’s Secretary of State or equivalent agency. The articles typically must include the foundation’s name, its principal office address, a registered agent authorized to receive legal documents, and a statement of charitable purpose. That purpose clause needs to track the language of Section 501(c)(3) closely enough to satisfy the IRS.3Office of the Law Revision Counsel. 26 U.S. Code 501 – Exemption from Tax on Corporations, Certain Trusts, Etc. Vague language about “doing good” won’t work. State the specific exempt purpose the foundation will pursue.
The articles also need a dissolution clause providing that if the foundation is ever wound up, its remaining assets go to another qualified 501(c)(3) organization and not to any private individual. This is required by federal Treasury Regulations, though some states have laws that automatically satisfy the requirement even without an express clause.
Board of Directors
The IRS expects independent oversight and a clear separation between governance and management. No federal law fixes a specific board size, but most organizations seeking 501(c)(3) status appoint at least three to five unrelated directors. Too few directors, or a board stacked with family members, invites scrutiny during the application and creates conflicts of interest down the road.
Conflict of Interest Policy
Form 1023 asks whether you have adopted a written conflict of interest policy. The policy should require officers and directors to disclose situations where their personal financial interests conflict with the foundation’s mission, and it should bar conflicted individuals from voting on those matters.4Internal Revenue Service. Form 1023: Purpose of Conflict of Interest Policy Adopting one is technically optional. Applying without one signals weak governance and can slow review.
Get an Employer Identification Number
Before you can apply for tax-exempt status, the foundation needs an EIN from the IRS. This number is required for all federal tax filings and to open a bank account.
Wait until state incorporation is complete before applying. The IRS treats the organization as legally formed when you request the EIN, and the clock immediately starts on a critical compliance rule: if the organization fails to file a required annual return for three consecutive years, its tax-exempt status is automatically revoked.5Internal Revenue Service. Obtaining an Employer Identification Number for an Exempt Organization The online application through the IRS website is the fastest route and issues the number immediately.
Prepare Bylaws and Projected Budgets
A nonprofit corporation needs bylaws; a charitable trust needs a trust agreement. Either document will be reviewed by the IRS as part of the exemption application. Beyond the dissolution clause, the bylaws should address how directors are elected and removed, how meetings are called and conducted, what constitutes a quorum, and how the bylaws themselves are amended.
New organizations also have to prepare projected financials. Form 1023 requires three years of financial data. If the organization has existed for less than a year, that means good-faith projections of income and expenses for the current year plus the next two.6Internal Revenue Service. Instructions for Form 1023 The IRS wants to see revenue and spending patterns consistent with a real charitable operation.
File Form 1023 for Federal Tax-Exempt Status
The application must be filed electronically through Pay.gov. Paper applications are no longer accepted. Most organizations file Form 1023, which carries a $600 user fee.7Internal Revenue Service. Form 1023 and 1023-EZ – Amount of User Fee
Smaller organizations may qualify for the streamlined Form 1023-EZ, which costs $275. To be eligible, projected annual gross receipts cannot exceed $50,000 in any of the next three years, and total assets cannot exceed $250,000.8Internal Revenue Service. Instructions for Form 1023-EZ The 1023-EZ eligibility worksheet includes disqualifying factors beyond those dollar limits, so complete the worksheet before assuming you qualify. Private foundations are among the organizations that generally cannot use the EZ form.
The full Form 1023 requires a detailed narrative describing how the foundation will carry out its mission, biographical and compensation information for all officers and directors, and the projected financials. Vague activity descriptions and incomplete financials are the top reasons the IRS sends follow-up questions, which adds months to the timeline.
The 27-Month Filing Deadline
File Form 1023 within 27 months from the end of the month your organization was formed and the IRS can recognize tax-exempt status retroactively to the date of formation. Miss that window and the exemption is recognized only from the date you actually filed.9Internal Revenue Service. Form 1023: Purpose of Questions About Organization Applying More Than 27 Months After Date of Formation Donations received before the effective date are not deductible for donors, and the organization may owe income tax on revenue earned during that gap.
IRS Review and the Determination Letter
An IRS agent is assigned to review the application after filing. About 80 percent of Form 1023 determinations are issued within 191 days.10Internal Revenue Service. Where’s My Application for Tax-Exempt Status? The agent may contact you during that window with questions or requests for documents. If approved, the IRS issues a determination letter, which is the official confirmation of 501(c)(3) status. Keep it permanently; you will need it for state registrations, grant applications, and to prove exempt status to donors.
Annual Filings Every 501(c)(3) Has to Make
The determination letter is not the finish line. Every tax-exempt organization has annual obligations, and ignoring them leads to automatic loss of status.
Information Returns
Organizations with gross receipts of $50,000 or more file Form 990 or Form 990-EZ each year. Those with gross receipts normally below that threshold file Form 990-N, the brief electronic notice sometimes called the e-Postcard.11Internal Revenue Service. Exempt Organization Annual Filing Requirements Overview Private foundations file Form 990-PF regardless of income level.12Internal Revenue Service. Instructions for Form 990-PF (2025) Miss the applicable return for three consecutive years and tax-exempt status is automatically revoked under Section 6033(j).13Internal Revenue Service. Automatic Revocation of Exemption
Unrelated Business Income
If the foundation earns $1,000 or more in gross income from a business activity not substantially related to its charitable purpose, it must file Form 990-T and pay tax on that income. An organization that expects to owe $500 or more in that tax must also make quarterly estimated payments.14Internal Revenue Service. Unrelated Business Income Tax A gift shop selling items connected to the mission is generally fine. A commercial sideline run to generate revenue is where the problems start.
Public Disclosure
The annual information return, with all schedules and attachments, must be made available for public inspection for three years from the later of the filing due date or the actual filing date.15Internal Revenue Service. Public Disclosure and Availability of Exempt Organization Returns and Applications: Public Disclosure Overview Posting them online satisfies the copy-request requirement, but in-person inspection must still be allowed. Public charities may redact donor names and addresses; private foundations may not.
Extra Rules That Apply Only to Private Foundations
Private foundations carry a much heavier ongoing compliance load than public charities. Founders often miss this at formation, then run into it later. Treat these rules as part of the setup planning.
Excise Tax on Investment Income
Private foundations pay an annual excise tax of 1.39 percent on net investment income, including interest, dividends, rents, and capital gains. The tax is reported on Form 990-PF and applies every year regardless of how much the foundation gives away.
Five Percent Minimum Distribution
A private nonoperating foundation must distribute at least 5 percent of the fair market value of its non-charitable-use assets each year for qualifying charitable purposes.16Office of the Law Revision Counsel. 26 USC 4942 – Taxes on Failure to Distribute Income Fall short and the foundation owes a 30 percent tax on the undistributed amount. If the shortfall isn’t corrected after IRS notice, a second-tier tax of 100 percent kicks in. This rule keeps foundations funded by investment portfolios from sitting on their money indefinitely.
Self-Dealing Prohibitions
Federal law broadly prohibits financial transactions between a private foundation and its “disqualified persons,” a group that includes founders, substantial contributors, foundation managers, and their family members. Banned transactions include sales or exchanges of property, loans, furnishing goods or services, and paying unreasonable compensation.17GovInfo. 26 USC 4941 – Taxes on Self-Dealing The initial penalty is 10 percent of the transaction amount on the person who engaged in the deal, plus 5 percent on any foundation manager who knowingly approved it, with much higher second-tier penalties if the transaction isn’t unwound. A few narrow exceptions exist, such as a disqualified person providing services to the foundation at no charge, but the working rule is to keep personal and foundation finances completely separate.
Lobbying and Political Activity
All 501(c)(3) organizations are barred from participating in political campaigns. Private foundations face additional excise taxes under Section 4945 if they spend money on lobbying, whether grassroots or direct.18Internal Revenue Service. Political and Lobbying Activities – Private Foundations Unlike public charities, private foundations cannot elect the Section 501(h) expenditure test that allows limited lobbying, so private foundations should avoid spending that could be characterized as trying to influence legislation.
Register in Every State Where You Solicit Donations
Roughly 40 states plus the District of Columbia require charitable organizations to register with a state agency before soliciting donations. Registration is usually handled by the state Attorney General’s office or a charities division within the Secretary of State’s office. Each state has its own forms, fees, and deadlines, and fundraising nationally can mean registering in every state where you solicit.
The process typically requires a copy of the IRS determination letter, the Articles of Incorporation, and a state-specific registration form. Most states require annual renewal with the most recent Form 990 or 990-PF and a renewal fee. Initial fees vary widely, from as low as $10 to several hundred dollars. Soliciting in a state that requires registration without registering can lead to fines and injunctions, so build state registration into the compliance calendar from day one.
