Two authorities decide whether an organization is a not-for-profit, and each answers a different question. The state where the organization is formed decides whether it exists as a nonprofit legal entity under state law. The Internal Revenue Service then decides, separately, whether that entity qualifies for exemption from federal income tax. Most organizations need both, and one does not substitute for the other.
The State Creates the Nonprofit Entity
Forming a not-for-profit starts at the state level. You file articles of incorporation, sometimes called a certificate of formation, with a designated state agency — usually the Secretary of State. That filing legally creates the organization, sets its governance structure, and places it under the state’s nonprofit corporation law. Every state sets its own filing requirements and fees, so the specifics depend on where you incorporate.
What state incorporation does is give the organization a legal existence: it can open a bank account, sign contracts, hold property, and apply for further classifications. What it does not do is make the organization tax-exempt. The state has said the entity exists as a nonprofit corporation. Whether the federal government treats it as tax-exempt is a separate decision made by a separate authority.
A useful way to think about it: the state issues the birth certificate. The federal designation is a different document, applied for separately, with its own criteria.
The IRS Decides Federal Tax-Exempt Status
The Internal Revenue Service is the federal agency that determines whether a nonprofit qualifies for exemption from federal income tax. When the IRS grants that status, the organization stops owing federal corporate income tax on revenue tied to its exempt purpose, which leaves more money for programs and operations.
The best-known designation is Section 501(c)(3), which covers organizations operated for religious, charitable, scientific, literary, or educational purposes, among others.1Internal Revenue Service. Exempt Purposes – Internal Revenue Code Section 501(c)(3) A major practical advantage of 501(c)(3) status is that donors can deduct their contributions on their own federal returns, which makes fundraising easier.2Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts
To obtain 501(c)(3) status, an organization files Form 1023 (or the streamlined Form 1023-EZ if it qualifies) with the IRS, submitting its state-filed articles of incorporation, bylaws, a description of planned activities, and financial projections. An IRS exempt organizations specialist reviews the application, may request additional information, and eventually issues a determination letter granting or denying the status.3Internal Revenue Service. Exempt Organizations Rulings and Determination Letters That determination letter is the document that proves federal tax-exempt status.
Section 501(c)(3) Is Not the Only Category
Section 501(c)(3) draws the most attention, but the Internal Revenue Code recognizes roughly 30 types of tax-exempt organizations.4Internal Revenue Service. Types of Tax-Exempt Organizations Common examples include:
- 501(c)(4) social welfare organizations, such as civic leagues and community groups. They can engage in more political advocacy than 501(c)(3)s, but donations to them are not tax-deductible.
- 501(c)(6) business leagues and trade associations, including chambers of commerce and professional associations.5Internal Revenue Service. Life Cycle of a Business League (Trade Association)
- 501(c)(7) social clubs, such as country clubs and hobby groups.
- 501(c)(19) veterans’ organizations composed of past or present members of the Armed Forces.
Each category has its own eligibility criteria and its own application form. Organizations seeking 501(c)(3) status file Form 1023; most other categories use Form 1024. In every case, though, the deciding authority is the same: the IRS.6Office of the Law Revision Counsel. 26 USC 501 – Exemption From Tax on Corporations, Certain Trusts, Etc.
Public Charity or Private Foundation
Once the IRS approves a 501(c)(3) application, it further classifies the organization as either a public charity or a private foundation. By default, the IRS treats every 501(c)(3) as a private foundation unless the organization demonstrates it qualifies as a public charity. Public charities generally must draw at least one-third of their revenue from relatively small donors, government grants, or other public charities. Private foundations are typically funded by a single family or small group and usually make grants rather than run programs. The distinction matters because private foundations face stricter rules and lower donor deduction limits — generally 30% of income compared with up to 60% for public charities — but the classification itself is still an IRS determination, made as part of the same approval.
Why You Need Both Determinations
Because the state and the IRS answer different questions, having only one determination leaves gaps.
An organization that is incorporated as a nonprofit in its state but has not obtained IRS recognition is a legal nonprofit entity under state law, but it is not federally tax-exempt. It owes federal income tax on its earnings, and donors cannot deduct their contributions. This is exactly the situation an organization ends up in if the IRS denies its application and it does not correct the problems or appeal, or if the IRS automatically revokes its status for failing to file annual returns for three consecutive years.7Office of the Law Revision Counsel. 26 USC 6033 – Returns by Exempt Organizations The state entity keeps existing; the federal benefits disappear.
Going the other direction is not really possible: the IRS will not grant tax-exempt status to an organization that does not already exist as a legal entity. The application requires a copy of the state-filed articles of incorporation and an Employer Identification Number, which the organization can only obtain after it is legally formed.8Internal Revenue Service. Form 1023 – EIN Required to Apply for Exemption State recognition has to come first, and federal recognition builds on it.
State Tax Exemptions Are a Separate Question Again
One boundary is worth flagging, because it catches new nonprofits off guard. A favorable IRS determination letter does not automatically exempt an organization from state taxes or state charitable registration requirements. State sales tax exemptions, state property tax exemptions, and state income tax exemptions each require their own applications with the relevant state agencies. Many states also require charitable organizations to register with a state agency before soliciting donations from the public, often with annual renewals.9Internal Revenue Service. Charitable Solicitation – State Requirements
In other words, the two-authority structure keeps operating even after you have both determinations in hand. The state that created the entity still controls state-level tax treatment and fundraising rules. The IRS controls federal tax treatment. Neither one speaks for the other, and an organization that wants the full set of nonprofit benefits has to satisfy both.
