Yes, nonprofits can make money, and many of them do. What the tax code prohibits is not earning a surplus but handing that surplus to insiders. Every dollar a 501(c)(3) takes in above what it spends has to stay inside the organization and support the charitable, educational, or other exempt purpose it was formed to pursue. That single rule, more than any other, is what separates a nonprofit from a business.
Where the Money Comes From
Most nonprofit revenue is tied directly to the mission. A museum charges admission, a university collects tuition, a professional association collects dues, a hospital bills for care. Because those activities further the exempt purpose, the income they produce is generally not subject to federal income tax. Steady mission-related earnings are what let an organization keep experienced staff, maintain facilities, and plan beyond the next fundraising cycle.
Donations and grants sit alongside earned revenue. Contributions to a 501(c)(3) are deductible on the donor’s own return, which is a large part of why individuals and foundations give. Government and foundation grants often fund specific projects and carry their own reporting strings. Together these can make up a significant share of a budget, but relying on them alone makes planning difficult.
Corporate sponsorships are a third stream, and how the IRS classifies them matters. A qualified sponsorship payment is one where the business gets nothing substantial in return beyond acknowledgment: a logo on a banner, a name in the program. Cross the line into promotion, with comparative language, pricing, or a call to action, and the IRS treats the payment as advertising income subject to unrelated business income tax.1Office of the Law Revision Counsel. 26 U.S. Code 513 – Unrelated Trade or Business
Why “Nonprofit” Doesn’t Mean “No Surplus”
The defining legal feature of a tax-exempt organization is the ban on private inurement. Under 26 U.S.C. § 501(c)(3), no part of the organization’s net earnings may benefit any private shareholder or individual.2Office of the Law Revision Counsel. 26 USC 501 – Exemption From Tax on Corporations, Certain Trusts, Etc. A for-profit company pays its owners through dividends or buybacks. A nonprofit has no owners in that sense, and its surplus has to be reinvested in the work.
The inurement rule targets insiders: officers, directors, key employees, anyone with influence over the organization. A related and broader doctrine, private benefit, applies to anyone at all, including outsiders. An organization can run afoul of the private benefit rule even when it pays fair market value, if the arrangement gives a meaningful advantage to a private party instead of the charitable class it exists to serve.3eCFR. 26 CFR 1.501(c)(3)-1 – Organizations Organized and Operated for Religious, Charitable, Scientific, Testing for Public Safety, Literary, or Educational Purposes Either violation can cost the organization its tax-exempt status.
When an insider does receive more than what they gave the organization in return, the IRS calls it an excess benefit transaction. The insider owes an excise tax of 25 percent of the excess. If it isn’t corrected in time, that tax rises to 200 percent. Board members and managers who knowingly approved the deal owe a separate 10 percent tax on the excess, capped at $20,000 per transaction.4Office of the Law Revision Counsel. 26 U.S. Code 4958 – Taxes on Excess Benefit Transactions
The rule follows the organization even at the end of its life. If a 501(c)(3) dissolves, whatever remains has to go to another exempt-purpose organization or to a government body for a public purpose, and that commitment must appear in the founding documents.5Internal Revenue Service.

Paying Staff Is Not a Violation
Salaries, benefits, and executive pay are ordinary operating expenses, not private inurement. The standard the IRS applies is reasonable compensation: what a similar organization would ordinarily pay for similar work under similar circumstances.6Internal Revenue Service. Exempt Organization Annual Reporting Requirements – Meaning of Reasonable Compensation Compensation is measured broadly: salary, bonuses, severance, deferred pay, fringe benefits, liability insurance premiums, even forgone interest on loans all count.7Internal Revenue Service. Intermediate Sanctions – Compensation
Boards that want protection when setting executive pay can follow a three-part process that creates a rebuttable presumption of reasonableness. The compensation must be approved in advance by an independent body with no financial conflict, that body must rely on comparability data from similar organizations, and it must document the basis for the decision at the time it makes it. Meeting all three shifts the burden of proof to the IRS if the pay is ever challenged.8eCFR. 26 CFR 53.4958-6 – Rebuttable Presumption That a Transaction Is Not an Excess Benefit Transaction Skipping any of the steps doesn’t make the compensation illegal, but it leaves the organization more exposed.
When Nonprofit Income Does Get Taxed
Not every dollar a nonprofit earns is tax-free. If the organization regularly runs a trade or business that isn’t substantially related to its exempt purpose, that income is unrelated business taxable income.9Office of the Law Revision Counsel. 26 USC 513 – Unrelated Trade or Business A university operating a commercial pharmacy open to the public, or a charity running a paid parking lot for neighborhood commuters, would generate UBTI. The tax keeps nonprofits from using their exempt status to undercut for-profit competitors.
UBTI is taxed at the 21 percent corporate rate.10Office of the Law Revision Counsel. 26 U.S. Code 11 – Tax Imposed The first $1,000 of gross unrelated business income is exempt by statute.11Office of the Law Revision Counsel. 26 U.S. Code 512 – Unrelated Business Taxable Income Any organization at or above that threshold files Form 990-T to report and pay the tax.12Internal Revenue Service. Instructions for Form 990-T If the unrelated side of the operation grows large enough to become a primary activity, the IRS can revoke exemption altogether.
Several categories of income stay outside UBTI even when the activity looks commercial. Businesses run substantially by unpaid volunteers, such as a charity bake sale, are excluded. Thrift store sales of donated merchandise are excluded when substantially all the goods came in as gifts. Cafeterias, bookstores, and similar operations run mainly for the convenience of students, patients, or employees are excluded. And passive investment income, including dividends, interest, royalties, and most rents, is generally outside UBTI.13Internal Revenue Service. Unrelated Business Income Tax Exceptions and Exclusions
What the Surplus Actually Does
A year that ends with money left over isn’t producing profit in the business sense. The remaining funds belong to the organization, and how the board puts them to work shapes its long-term stability.
A common move is to build a board-designated operating reserve, a cushion against a soft fundraising year or an unexpected expense. Three to six months of operating costs is a frequent target, though the right figure depends on the size of the organization and how predictable its revenue is. Surplus can also fund capital improvements: a building, better technology, expanded program capacity. Some organizations put surplus into an endowment, where investment returns can support scholarships, research, or core operations indefinitely.
Whatever the board decides, the allocation has to be documented and defensible as advancing the exempt purpose. Surplus that ends up in an insider’s pocket instead of the mission is exactly what the excess benefit transaction rules exist to punish.
Keeping the Status That Makes This Possible
The tax treatment described here depends on staying in good standing with the IRS. Exempt organizations file an annual return in the 990 series, with the specific form determined by size. The consequence that matters most for a nonprofit’s finances is at the far end: an organization that fails to file its required return for three consecutive years automatically loses its tax-exempt status.14Internal Revenue Service. Exempt Organizations Annual Reporting Requirements – Filing Procedures – Late Filing of Annual Returns Regaining exemption after that means a new application and, in many cases, paying tax for the period the organization was off the rolls.
