Nonprofits pay their employees the same way any business does: through regular payroll, with federal income tax, Social Security, and Medicare withheld from each check. Tax-exempt status applies to the organization’s income, not to the people who work there. What sets nonprofit payroll apart is a set of guardrails on top of ordinary employer rules — compensation has to be reasonable for the work performed, no earnings can flow to insiders as profit, and the pay of top staff is disclosed on a public tax return every year.
Where the Payroll Money Comes From
Salaries come out of the same pot as other operating expenses, but the pot has compartments. Unrestricted donations are the most flexible because the organization can spend them on any legitimate cost, including wages. Program service revenue — tuition, hospital charges, counseling fees, ticket sales — is often the largest single source and routinely funds staff pay.
Grants from governments and foundations are a different animal. Restricted grants are legally tied to specific projects, and their funds cannot be shifted to general payroll unless the agreement says so. Organizations receiving federal grants can recover a share of administrative costs, including support-staff salaries, through a negotiated indirect cost rate. A nonprofit that has never negotiated one with a federal agency can use a flat rate of up to 15 percent of modified total direct costs without any additional documentation, and that rate stays in place until the organization opts to negotiate a formal one.1eCFR. 2 CFR 200.414 – Indirect Costs Tracking which dollars pay which employees matters: using restricted funds for unauthorized purposes exposes the organization to grant clawbacks and potential fraud liability.
Payroll Taxes the Nonprofit Still Owes
A tax-exempt employer is responsible for federal income tax withholding, Social Security tax, and Medicare tax on employee wages, and reports them quarterly on Form 941.2Internal Revenue Service. Exempt Organizations: What Are Employment Taxes3Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates4Social Security Administration. Contribution and Benefit Base Earnings above the cap escape Social Security tax. Medicare tax is 1.45 percent on each side with no wage limit.
Officers of a nonprofit corporation count as employees for payroll tax purposes even when the organization uses a different title, unless the officer performs no services and receives no compensation.5Internal Revenue Service. Exempt Organizations: Compensation of Officers Volunteer board members who only receive reimbursement under an accountable plan are not on payroll.
Anyone responsible for collecting and depositing withheld payroll taxes — including officers, directors, and board members — can be held personally liable through the Trust Fund Recovery Penalty if those taxes go unpaid, regardless of whether the failure was the organization’s decision or the individual’s.6Internal Revenue Service.

FUTA and State Unemployment
Organizations with 501(c)(3) status are fully exempt from the Federal Unemployment Tax Act, and that exemption cannot be waived.2Internal Revenue Service. Exempt Organizations: What Are Employment Taxes Other tax-exempt categories, including 501(c)(4) social welfare organizations and 501(c)(6) trade associations, do not get this break and pay FUTA like any private employer.
State unemployment insurance is separate. Even 501(c)(3) organizations generally owe state unemployment contributions. Most states let nonprofits choose between paying the standard tax rate based on claims history or electing to become a “reimbursable employer” that pays the state dollar-for-dollar for actual claims filed by former employees. The reimbursable route saves money for organizations with stable staffing and hurts during a wave of layoffs.
The Reasonable Compensation Limit
Every dollar a nonprofit pays an employee has to reflect a reasonable amount for the work performed. The IRS enforces that limit through excise taxes on the individuals involved, not just penalties on the organization.
Under Internal Revenue Code Section 4958, an “excess benefit transaction” occurs when someone with substantial influence over the organization receives compensation exceeding the fair market value of their services.7Office of the Law Revision Counsel. 26 USC 4958 – Taxes on Excess Benefit Transactions The IRS compares pay to what similar organizations, both nonprofit and for-profit, pay for comparable roles in comparable locations. Budget size, job complexity, and regional cost of living all matter. The rule covers every form of compensation: base salary, bonuses, deferred pay, and non-cash benefits.
When pay crosses the line, three taxes can apply:
- An initial tax of 25 percent of the excess benefit, paid by the recipient.7Office of the Law Revision Counsel. 26 USC 4958 – Taxes on Excess Benefit Transactions
- A 10 percent tax on any organization manager who knowingly approved it, capped at $20,000 per transaction.7Office of the Law Revision Counsel. 26 USC 4958 – Taxes on Excess Benefit Transactions
- An additional tax of 200 percent of the excess benefit if the recipient does not return it within the allowed correction period.7Office of the Law Revision Counsel. 26 USC 4958 – Taxes on Excess Benefit Transactions
These taxes come out of the individual’s own pocket. If the organization reimburses a disqualified person for the excise tax, the IRS can treat that reimbursement as another excess benefit transaction. In severe or repeated cases, the IRS can revoke the organization’s 501(c)(3) status. Individuals owing these excise taxes file Form 4720 by the 15th day of the 5th month after the end of their tax year.8IRS.gov. 2025 Instructions for Form 4720
How Boards Set Executive Pay
Salary decisions for senior leaders are usually delegated to an independent compensation committee — board members with no financial stake in the outcome. Following a specific procedure creates a legal shield known as the rebuttable presumption of reasonableness, which shifts the burden onto the IRS to prove pay is excessive rather than the organization having to prove it is fair.
The procedure has three parts. The decision must be made by an independent body free of conflicts. That body must rely on objective comparability data, meaning independent salary surveys, published compensation studies, or written offers the executive received from other organizations. For smaller nonprofits with annual gross receipts under $1 million, data from at least three comparable organizations in similar communities is generally sufficient. The board must document its analysis, including the data reviewed and the names of members who voted, before the later of the next board meeting or 60 days after the decision. Skipping the documentation is where most nonprofits lose the protection.
Benefits and 403(b) Retirement Plans
Total compensation at nonprofits often relies on benefits, because a strong benefits package can attract talent without pushing base salary into unreasonable territory. Several common benefits are excluded from taxable wages, and payroll taxes are not withheld on them:
- Educational assistance up to $5,250 per year in tuition and related expenses under a formal program. The provision that let employer payments of student loan principal count toward this exclusion expired on January 1, 2026.9Internal Revenue Service. Frequently Asked Questions About Educational Assistance Programs
- Dependent care assistance up to $7,500 per year, or $3,750 for married employees filing separately.10Internal Revenue Service. Employer’s Tax Guide to Fringe Benefits
- Commuter benefits — transit passes, vanpool costs, and qualified parking — excludable up to $340 per month each for 2026.10Internal Revenue Service. Employer’s Tax Guide to Fringe Benefits
- Business use of an employer-provided cell phone, when the phone was given primarily for a legitimate business reason rather than as a morale perk.10Internal Revenue Service. Employer’s Tax Guide to Fringe Benefits
One retirement plan is specific to this sector. Only organizations exempt under Section 501(c)(3), public schools, and certain ministers can sponsor a 403(b) plan.11Office of the Law Revision Counsel. 26 USC 403 – Taxation of Employee Annuities These work much like 401(k)s: employees defer pre-tax dollars, and the organization can add matching or discretionary contributions. For 2026, the employee deferral limit is $24,500. Workers aged 50 and older can add $8,000 in catch-up contributions, and those aged 60 through 63 qualify for a higher catch-up of $11,250.12Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Employer contributions can go on top, subject to the overall annual addition limit under Section 415.
Overtime and Minimum Wage
The Fair Labor Standards Act does not automatically cover nonprofits. It reaches a nonprofit as a whole only when the organization runs commercial activities — a gift shop, veterinary services, a thrift store — that generate at least $500,000 in annual sales volume. Contributions, membership dues, and donations used for charitable purposes do not count toward that threshold.13U.S. Department of Labor. Fact Sheet 14A: Non-Profit Organizations and the Fair Labor Standards Act (FLSA) Even where the organization is not covered, individual employees who personally engage in interstate commerce, such as handling credit card transactions or ordering supplies from other states, can still be protected.
When the FLSA applies, covered employees are entitled to federal minimum wage and overtime pay of one and a half times their regular rate for hours over 40 in a workweek. State minimum wages that exceed the federal rate control. Salaried employees can be exempt from overtime only when they meet both a duties test (executive, administrative, or professional work) and a salary threshold. After the federal court decision vacating the Department of Labor’s 2024 rule, the enforced salary level is currently $684 per week, or $35,568 annually.14U.S. Department of Labor. Overtime Pay Paying someone a salary alone does not make them exempt.
Employees, Contractors, Interns, and Volunteers
Nonprofits often bring on consultants, grant writers, and event coordinators as independent contractors. Misclassifying someone who should be an employee is one of the more expensive mistakes in the sector. The IRS weighs three categories of evidence: behavioral control over how and when the work is done, financial control over payment, expenses, and tools, and the overall relationship between the parties.15Internal Revenue Service. Independent Contractor (Self-Employed) or Employee No single factor decides it. An organization that sets a contractor’s schedule, provides their laptop, and renews the arrangement year after year is probably employing them, whatever the contract says.
If the IRS reclassifies a contractor as an employee during an audit, the organization owes back employment taxes, penalties, and interest. Section 530 relief can shield a nonprofit from that liability when it filed 1099s consistently, never treated anyone in a similar role as an employee, and had a reasonable basis for the classification such as industry practice or advice from a tax professional.16Internal Revenue Service. Worker Reclassification – Section 530 Relief
Volunteers and unpaid interns raise a related question. The Department of Labor uses a seven-factor “primary beneficiary test” to decide whether an intern is actually an employee entitled to minimum wage.17U.S. Department of Labor. Fact Sheet 71: Internship Programs Under the Fair Labor Standards Act The factors look at whether both sides understand there is no expectation of pay, whether the internship provides training tied to formal education, whether the schedule fits the academic calendar, whether the duration is limited to meaningful learning, whether the intern’s work supplements rather than replaces paid staff, and whether either side treats it as a guarantee of a paid job later. Courts weigh all of them together, and the analysis tilts toward protecting the intern. A nonprofit that uses unpaid interns to do the same work its paid employees do is exposed to a wage claim.
Public Disclosure Through Form 990
Nonprofit compensation is not private. Organizations filing Form 990 must list every current officer, director, and trustee, paid or not. They must also report up to 20 “key employees” — those with significant organizational responsibilities and reportable compensation exceeding $150,000 — plus the five highest-compensated non-officer employees earning at least $100,000.18Internal Revenue Service. Form 990 Part VII and Schedule J Reporting Executive Compensation Individuals Included Schedule J breaks the pay down into base compensation, bonus and incentive payments, and retirement contributions. The returns are public records, and donors and watchdog organizations routinely use them to evaluate spending on leadership.
Late or inaccurate filings trigger penalties that scale with the organization’s size, ranging from $20 per day for smaller organizations up to $120 per day for larger ones, with dollar caps at each level.19Internal Revenue Service. Filing Procedures: Late Filing of Annual Returns Paying employees well is compatible with tax-exempt status. Paying them without documenting how the numbers were chosen is where the trouble starts.
