These Are Not the Same Thing
"Nonprofit" and "501(c)(3)" get used interchangeably all the time — by founders, donors, and even some professionals who should know better. But they refer to two different things, and understanding the distinction matters if you're starting an organization or trying to understand how one works.
The short version: a nonprofit is a type of corporation formed under state law. A 501(c)(3) is a federal tax-exempt status granted by the IRS. You can be a nonprofit without being a 501(c)(3), and the process for becoming each one is separate.
What "Nonprofit" Actually Means
A nonprofit corporation is a legal entity formed at the state level, just like any other corporation. You create it by filing articles of incorporation with your state's Secretary of State (or equivalent office). The filing requirements, fees, and forms vary by state.
What makes it a "nonprofit" corporation rather than a regular business corporation is its purpose and structure. A nonprofit corporation is organized for a purpose other than generating profit for its owners. It doesn't have shareholders or owners who receive dividends. Any revenue the organization generates is used to further its mission, not distributed to individuals.
But here's the key point: incorporating as a nonprofit at the state level does not automatically make you tax-exempt. It's just the first step. After you incorporate, you still need to apply to the IRS for federal tax-exempt status — and that's where 501(c)(3) comes in.
What 501(c)(3) Means
Section 501(c)(3) of the Internal Revenue Code defines a specific category of tax-exempt organizations. To qualify, an organization must be organized and operated exclusively for religious, charitable, scientific, educational, or other specified exempt purposes.
When the IRS grants 501(c)(3) status, the organization gets two major benefits: it doesn't pay federal income tax on revenue related to its exempt purpose, and donations to it are tax-deductible for the donors.
Getting 501(c)(3) status requires filing an application with the IRS — either Form 1023 (the full application) or Form 1023-EZ (the streamlined version for smaller organizations). The IRS reviews the application, and if approved, issues a determination letter confirming your tax-exempt status.
This process is entirely separate from state incorporation. The IRS doesn't care whether you're incorporated in Delaware or California — they're evaluating whether your organization qualifies for federal tax exemption.
So Which Comes First?
State incorporation comes first. You need to be a legal entity before you can apply for tax-exempt status. The typical sequence is:
First, you incorporate as a nonprofit corporation in your state. This gives you a legal entity that can open a bank account, enter contracts, and operate. Second, you apply to the IRS for 501(c)(3) status. This usually happens shortly after incorporation, though technically you can operate as a nonprofit corporation without seeking federal tax exemption.
Many founders try to do both simultaneously, but the IRS application asks for your articles of incorporation, your EIN (employer identification number), and your bylaws — so the state-level work needs to happen first.
Can You Be a Nonprofit Without Being a 501(c)(3)?
Yes. Not every nonprofit is a 501(c)(3). There are several scenarios where this happens:
You haven't applied yet. Between the time you incorporate and the time the IRS approves your application, you're a nonprofit corporation without 501(c)(3) status. If you apply within 27 months of formation, your exemption can be retroactive to the date of incorporation.
You're a different type of exempt organization. Section 501(c) has dozens of subsections. Social welfare organizations are 501(c)(4). Trade associations are 501(c)(6). Social clubs are 501(c)(7). These are all nonprofits, but they're not 501(c)(3)s — and donations to them generally aren't tax-deductible.
You choose not to apply. Some organizations operate as nonprofit corporations without seeking any federal tax exemption. They're still nonprofits in the legal sense — they're organized for a non-profit purpose — but they don't have the tax benefits.
Why the Distinction Matters
For fundraising. Only 501(c)(3) organizations can offer donors a tax deduction for their contributions. If your organization relies on charitable donations, you need 501(c)(3) status. Donors will ask for it, and grant-making foundations will require it.
For grants. Most private foundations and many government agencies will only fund 501(c)(3) organizations. Without the determination letter, you're locked out of a significant portion of the funding landscape.
For credibility. The IRS determination letter signals to donors, partners, and the public that your organization has been vetted and meets federal standards for charitable operation. It's a mark of legitimacy.
For state tax exemptions. Many states require federal 501(c)(3) status as a prerequisite for state-level tax exemptions (sales tax, property tax, state income tax). The federal determination letter is your ticket to these exemptions.
The Full Formation Sequence
For anyone starting a charitable organization, the complete process looks like this:
Choose your state of incorporation. Draft and file articles of incorporation. Obtain an EIN from the IRS (this is free and can be done online). Draft bylaws and hold an organizational meeting. Apply for 501(c)(3) status with the IRS (Form 1023 or 1023-EZ). Once approved, apply for state tax exemptions. Register for charitable solicitation if your state requires it.
Each step has its own requirements, and they vary by state. The IRS process alone can take several months, so plan accordingly.

Frequently Asked Questions
Can a nonprofit lose its 501(c)(3) status?
Yes. The IRS automatically revokes 501(c)(3) status if an organization fails to file Form 990 for three consecutive years. Status can also be revoked for excessive lobbying, political campaign activity, private benefit to insiders, or operating outside the organization's exempt purpose. Reinstatement requires filing all missed returns and reapplying.
Are all nonprofits tax-exempt?
No. A nonprofit corporation formed under state law is not automatically tax-exempt. Federal tax exemption requires a separate application to the IRS. And not all tax-exempt organizations are 501(c)(3)s — social welfare organizations (501(c)(4)), trade associations (501(c)(6)), and social clubs (501(c)(7)) are tax-exempt but donations to them generally aren't tax-deductible.
How do I check if an organization has 501(c)(3) status?
Use the IRS Tax Exempt Organization Search tool at irs.gov. You can search by organization name or EIN. The database shows current exempt status, ruling date, and deductibility status. You can also check GuideStar (now Candid) for additional details including the organization's Form 990.
Do donors need my 501(c)(3) determination letter?
Donors themselves don't need it, but many ask for it — especially major donors and foundations. Your determination letter confirms that contributions to your organization are tax-deductible. Having it readily available builds trust and removes friction from the giving process. Most grant applications require a copy.
