Nonprofits are allowed to bring in more money than they spend, but what nonprofits do with profits is tightly restricted: the surplus cannot be paid out to founders, board members, or anyone else with a stake in the organization. Instead, it stays inside the organization and gets put back to work — expanding programs, paying staff, building reserves, upgrading facilities, and, if the nonprofit ever shuts down, going to another charitable organization. Federal tax law enforces this from every angle, and the penalties for breaking the rule are steep.
The Rule Against Paying Out Surplus
The foundational rule for any 501(c)(3) is that no part of its net earnings can benefit any private shareholder or individual.1Office of the Law Revision Counsel. 26 USC 501 – Exemption From Tax on Corporations, Certain Trusts, Etc Lawyers call this the non-distribution constraint. A nonprofit cannot pay dividends. It cannot distribute equity. It cannot split a good year’s surplus among its founders or directors. Even a small violation can cost the organization its tax-exempt status.2Internal Revenue Service. Overview of Inurement and Private Benefit Issues in IRC 501(c)(3)
Two overlapping doctrines carry the weight of this rule. Private inurement covers money or benefits flowing to an insider — a founder, officer, board member, or anyone else with substantial influence over the organization. Private benefit is broader, requiring that the nonprofit serve the public rather than any particular private party, even a party who is not technically an insider.
What Happens When Someone Takes Too Much
The IRS does not have to revoke exempt status every time an insider gets more than they should. It can instead impose graduated penalties, called intermediate sanctions, on the individual who received the improper benefit. That individual is labeled a “disqualified person,” meaning someone who had substantial influence over the organization’s affairs in the five years before the transaction.3Office of the Law Revision Counsel. 26 USC 4958 – Taxes on Excess Benefit Transactions
The penalty runs in two stages. First, the disqualified person owes a tax of 25 percent of the excess benefit, meaning whatever amount the payment exceeded fair market value. If the excess is not returned within the correction period, a second tax of 200 percent kicks in. Organization managers who knowingly approved the transaction face their own tax of 10 percent, capped at $20,000 per transaction.3Office of the Law Revision Counsel. 26 USC 4958 – Taxes on Excess Benefit Transactions All of that is on top of paying the money back.
Reinvesting Surplus in the Mission
The most direct use of a surplus is expanding the programs the nonprofit already runs. A food bank can stock better nutritional items or extend distribution hours. An educational charity can hand out more scholarships. A research organization can fund additional studies or hire specialized scientists. Surplus can also seed something new that fits the organization’s exempt purpose, like a homeless shelter starting a job-training program for residents.
This cycling of money back into the work is not just good practice. It is what donors, the public, and the federal government expect in exchange for the tax exemption.
Paying Staff Competitively
Nonprofits also use surplus to pay competitive salaries and benefits. The legal test is “reasonable compensation,” which the IRS defines as the amount that would ordinarily be paid for similar services by a similar organization in similar circumstances.4Internal Revenue Service. Exempt Organization Annual Reporting Requirements – Meaning of Reasonable Compensation Pay above that line can trigger the intermediate sanctions described above.
Boards can protect themselves by following a documented procedure — independent approval, comparable salary data, and a written record made at the time of the decision — that shifts the burden of proof onto the IRS if compensation is later challenged.5eCFR. 26 CFR 53.4958-6 – Rebuttable Presumption That a Transaction Is Not an Excess Benefit Transaction Organizations that skip it are not automatically in violation. They just carry the burden of proving fairness themselves.
Building a Reserve
A surplus year lets a nonprofit build an operating reserve, a cushion that keeps the doors open through a bad fundraising quarter, a delayed grant, or an unexpected expense. Common financial planning guidance points to three to six months of operating costs. Grantmakers often look at reserve levels before writing checks.
Reserves can grow too large. A cash pile that far outstrips what the mission requires can raise questions about whether the organization is actually operating for its exempt purpose.
Investing Those Funds
Once reserves exist, how they are invested is regulated. Private foundations face a specific federal excise tax on “jeopardizing investments” — highly speculative moves that could undermine the foundation’s ability to carry out its exempt purpose.6Internal Revenue Service. Taxes on Jeopardizing Investments Public charities are not subject to that specific tax. Their investment decisions are governed mostly by state law, and most states have adopted a version of the Uniform Prudent Management of Institutional Funds Act, which requires boards to invest with the care and loyalty of a prudent person in a similar role. Either way, reckless handling of donated money can put exempt status at risk if it looks like the organization is no longer operating for its stated purpose.
Facilities, Equipment, and Technology
Surplus also pays for the physical and digital backbone of the operation. Buying or renovating a permanent facility ends long-term rent. Donor management software, cybersecurity, and updated communications systems make daily work more efficient and protect sensitive data. Specialized equipment matters too: refrigerated vehicles for a food distribution nonprofit, diagnostic devices for a medical charity. These are the assets that let the organization scale without cutting into direct services.
When a Nonprofit Does Owe Income Tax
Nonprofits are not tax-exempt on absolutely everything. If a 501(c)(3) regularly carries on a trade or business that is not substantially related to its exempt purpose, the net income from that activity is subject to unrelated business income tax. Any organization with $1,000 or more in gross income from unrelated business activities has to file Form 990-T.7Internal Revenue Service. Unrelated Business Income Tax The tax rate is 21 percent, the same corporate rate for-profit companies pay.8Internal Revenue Service. Instructions for Form 990-T
Several big exceptions soften this. Activities where substantially all the work is done by unpaid volunteers are excluded, so a volunteer-run bake sale does not trigger the tax. Selling donated merchandise is excluded, which is why nonprofit thrift stores generally operate tax-free.9Internal Revenue Service. Unrelated Business Income Tax Exceptions and Exclusions Passive income like interest, dividends, and rent from real property is generally excluded as well. And paying the tax when it does apply is not itself a threat to exempt status. The nonprofit simply owes tax on the unrelated slice while continuing to operate tax-free on the rest.
How You Can See Where the Money Went
Federal law requires every tax-exempt organization to make its annual return and its original exemption application available for public inspection.10Internal Revenue Service. Public Disclosure and Availability of Exempt Organizations Returns and Applications – Documents Subject to Public Disclosure Returns must stay available for three years from the later of the due date or the actual filing date. With the exception of private foundations, an organization is not required to disclose the names and addresses of its donors.
The full Form 990 reports revenue, expenses, executive compensation, program accomplishments, and governance practices.11Internal Revenue Service. Instructions for Form 990 Return of Organization Exempt From Income Tax Third-party databases host these filings, so any donor, journalist, or watchdog group can see how much surplus a nonprofit generated and where it went. That visibility is a real constraint on how loosely a nonprofit can manage its money.
What Happens to the Surplus If the Nonprofit Closes
When a 501(c)(3) shuts down, its remaining assets cannot be divided among board members, staff, or anyone else inside the organization. Federal law requires that any leftover funds and property go to another organization with a qualifying exempt purpose, or to a government entity for a public purpose.12Internal Revenue Service. Does the Organizing Document Contain the Dissolution Provision Required Under Section 501(c)(3) The rule applies whether the closure is voluntary or forced.
The IRS wants to see this commitment written into the organization’s articles of incorporation or trust agreement before it will grant exempt status in the first place. State law layers additional requirements on top. The federal baseline stays constant: charitable assets keep serving charitable purposes, even after the organization that built them is gone.
