No. Not all nonprofits are tax exempt. Forming a nonprofit under state law and holding federal tax-exempt status are two different things, and an organization can easily be one without being the other. State incorporation creates the legal entity; federal tax exemption is a separate status granted by the IRS under specific sections of the Internal Revenue Code, and in most cases it requires a formal application. Even organizations that receive the exemption still owe tax on certain kinds of income.
Nonprofit Status and Tax-Exempt Status Are Different Things
A nonprofit is a corporate structure. It is created by filing articles of incorporation with a state agency, usually the Secretary of State, along with a statement of purpose, initial directors, and a registered agent address. Filing fees generally run between $30 and $150. Once the state approves the filing, the organization can sign contracts, open bank accounts, and hire staff. What defines it as nonprofit is that surplus revenue goes back into the mission rather than to owners or shareholders.
None of that says anything about taxes. At the point of state incorporation, the IRS treats the new entity like any other corporation. It owes federal income tax on its net earnings unless it takes the separate step of applying for, and receiving, a federal tax exemption. The word “nonprofit” on a state charter does not reduce federal income-tax liability on its own.
What a Nonprofit Without Exempt Status Owes
A nonprofit that has not obtained federal tax-exempt recognition, and does not qualify for one of the automatic exceptions described below, files a corporate income-tax return and pays the standard federal corporate income-tax rate on its net income. This catches many founders by surprise.
The fundraising consequence is often just as important. Donors who give to a nonprofit that lacks 501(c)(3) status generally cannot deduct their contributions on their own tax returns. Individual donors and virtually all private foundations require proof of 501(c)(3) status before making gifts or grants, so an organization without a determination letter has a harder time raising money in the first place.
How a Nonprofit Becomes Federally Tax Exempt
The Internal Revenue Code lists more than two dozen categories of organizations that can qualify for exemption from federal income tax. Section 501(c)(3) is the most widely recognized, covering organizations operated for religious, charitable, scientific, educational, or literary purposes, among others.1Office of the Law Revision Counsel. 26 USC 501 – Exemption From Tax on Corporations, Certain Trusts, Etc Section 501(c)(4) covers civic leagues and social welfare organizations under different rules.2eCFR. 26 CFR 1.501(c)(4)-1 Civic Organizations and Local Associations of Employees Other categories include labor unions under 501(c)(5), trade associations under 501(c)(6), and fraternal societies under 501(c)(8).
To earn exempt status, an organization must pass two tests. The organizational test requires the founding documents to limit the group’s purpose to activities permitted under its chosen tax-code category. The operational test requires the organization to actually spend its time and money on those purposes. For a 501(c)(3), this includes a ban on participating in political campaigns and a restriction on devoting a significant share of activities to lobbying.1Office of the Law Revision Counsel. 26 USC 501 – Exemption From Tax on Corporations, Certain Trusts, Etc Failing either test means the organization is treated as a regular taxable corporation regardless of its nonprofit charter.
Applications are submitted electronically through Pay.gov.3Internal Revenue Service. Applying for Tax Exempt Status Organizations seeking 501(c)(3) status file Form 1023 or, if they qualify, the streamlined Form 1023-EZ.4Internal Revenue Service. About Form 1023, Application for Recognition of Exemption Under Section 501(c)(3) of the Internal Revenue Code Other 501(c) categories use Form 1024 or Form 1024-A.5Internal Revenue Service. About Form 1024, Application for Recognition of Exemption Under Section 501(a) The non-refundable user fee is $600 for the full Form 1023 and $275 for Form 1023-EZ.6Internal Revenue Service. Form 1023 and 1023-EZ: Amount of User Fee To qualify for the 1023-EZ, annual gross receipts must not have exceeded $50,000 in any of the past three years, must not be projected to exceed $50,000 in any of the next three, and total assets cannot exceed $250,000.7IRS.gov. Instructions for Form 1023-EZ If approved, the IRS issues a determination letter — the official proof the organization is exempt from federal income tax.
One more point worth knowing when picking a category: contributions to a 501(c)(3) are generally deductible as charitable contributions on the donor’s federal income-tax return, but contributions to a 501(c)(4) generally are not.8Internal Revenue Service. Donations to Section 501(c)(4) Organizations A 501(c)(4) can do more political and lobbying work, but donors lose the charitable deduction. That trade-off shapes which structure fits an organization’s fundraising strategy.
Nonprofits That Are Exempt Without Applying
Not every tax-exempt nonprofit has to file an application. Churches, their integrated auxiliaries, and conventions or associations of churches are automatically treated as 501(c)(3) organizations if they meet the statutory requirements, and they are not required to apply for a determination letter.9Internal Revenue Service. Churches, Integrated Auxiliaries and Conventions or Associations of Churches Donors can claim a charitable deduction for gifts to a qualifying church even if it has never sought IRS recognition. Churches are also exempt from the annual filing requirements that apply to other tax-exempt organizations.10Office of the Law Revision Counsel. 26 USC 6033 – Returns by Exempt Organizations
Small nonprofits other than private foundations, with annual gross receipts normally at or below $5,000, are also excused from filing a formal application.11Office of the Law Revision Counsel. 26 USC 508 – Special Rules With Respect to Section 501(c)(3) Organizations Many churches and small organizations still choose to apply because a determination letter gives donors, grantmakers, and the organization’s own leadership concrete proof of exempt status.
Taxes Even Exempt Nonprofits Still Pay
Tax-exempt status does not mean an organization is free from every federal tax. Two obligations catch exempt organizations most often.
Unrelated Business Income Tax
When a nonprofit earns income from a trade or business that is regularly carried on and not substantially related to its exempt purpose, that income is subject to unrelated business income tax.12Internal Revenue Service. Unrelated Business Income Defined A university bookstore selling textbooks to students serves an educational purpose, but income from an unrelated retail operation open to the general public could be taxable. Any exempt organization with $1,000 or more in gross income from an unrelated business must file Form 990-T.13IRS.gov. Instructions for Form 990-T A specific deduction of $1,000 applies against unrelated business taxable income, so small amounts of side revenue may not produce an actual tax bill even though filing is still required.14Office of the Law Revision Counsel. 26 USC 512 – Unrelated Business Taxable Income
Employment Taxes
Nonprofits with employees generally must withhold and pay federal employment taxes, including Social Security at 6.2% on earnings up to $184,500 in 2026 and Medicare at 1.45% on all earnings.15Social Security Administration. Contribution and Benefit Base Organizations described in 501(c)(3) are exempt from Federal Unemployment Tax, which other employers must pay.16Internal Revenue Service. Section 501(c)(3) Organizations – FUTA Exemption That FUTA exemption does not extend to nonprofits under other 501(c) categories.
State Taxes and Fundraising Registration Are Separate
Federal tax-exempt status does not automatically exempt a nonprofit from state-level taxes. Most states impose their own corporate income tax, sales tax, or both, and each requires a separate application. Many states ask for a copy of the IRS determination letter as part of the state exemption application, but the federal letter alone does not activate state-level relief. Organizations that skip the state exemption process may owe state corporate income tax or be required to collect and remit sales tax even though they pay no federal income tax.
Roughly 40 states also require nonprofits to register before soliciting donations from residents.17Internal Revenue Service. Charitable Solicitation – Initial State Registration This is separate from both state tax exemption and federal tax-exempt status. An organization that runs a fundraising campaign, including an online campaign that reaches donors in other states, may need to register in every state where it actively seeks contributions. Some states exempt churches and small charities from registration, but the specifics vary. Failing to register can bring penalties and, in some states, an order to stop fundraising until the organization complies.
Keeping Exempt Status Once You Have It
Tax-exempt organizations must file an annual information return from the Form 990 series.18Internal Revenue Service. Annual Filing and Forms The version depends on size:
- Form 990-N (e-Postcard) is available to small organizations whose annual gross receipts are normally $50,000 or less.19Internal Revenue Service. Annual Electronic Filing Requirement for Small Exempt Organizations – Form 990-N (e-Postcard)
- Form 990-EZ covers mid-sized organizations above the 990-N threshold.
- Form 990 is required for larger organizations with higher gross receipts or total assets.
An organization that fails to file its required return for three consecutive years automatically loses its tax-exempt status.18Internal Revenue Service. Annual Filing and Forms The revocation is automatic; the IRS does not send a warning first. Churches and certain religious organizations are exempt from these annual filing requirements and so are not subject to automatic revocation for failure to file.10Office of the Law Revision Counsel. 26 USC 6033 – Returns by Exempt Organizations
Exempt organizations also must ensure that no part of their net earnings benefits private individuals, a rule known as the prohibition on private inurement. Compensation paid to officers and directors must be reasonable and reflect fair market value. For 501(c)(3) organizations, engaging in political campaign activity or devoting a substantial portion of resources to lobbying can result in loss of exempt status.1Office of the Law Revision Counsel. 26 USC 501 – Exemption From Tax on Corporations, Certain Trusts, Etc An organization that loses 501(c)(3) status for these reasons is also barred from converting to 501(c)(4) status.
An organization whose status is automatically revoked must apply for reinstatement using a new exemption application and the standard user fee; the IRS does not restore the status on its own.20Internal Revenue Service. Automatic Revocation – How to Have Your Tax-Exempt Status Reinstated During the gap period, the organization is treated as a taxable entity, and income earned in those years may be subject to corporate income tax.
