Employees of a nonprofit can volunteer for their nonprofit employer, but only if the volunteer work is genuinely different from what they’re paid to do, is freely given, and doesn’t displace paid staff. The Fair Labor Standards Act treats any hours spent on the same kind of work an employee is hired to perform as compensable time, whatever the organization chooses to call it. Get the line wrong and the nonprofit owes wages, overtime, and potentially penalties on top.
The Three Conditions That Have to Hold
The Department of Labor’s longstanding position is that individuals may volunteer time to religious, charitable, civic, or humanitarian nonprofits without triggering FLSA coverage, provided the arrangement meets a specific set of conditions.1U.S. Department of Labor. Fact Sheet 14A – Non-Profit Organizations and the Fair Labor Standards Act When the volunteer is already on the payroll, three things need to be true at once.
First, the service has to be freely given. That means no pressure, no coercion, and no expectation of compensation or job benefit. If a supervisor hints that volunteering will factor into a performance review, or if employees who don’t sign up quietly lose shifts, the “voluntary” part collapses.
Second, the volunteer work cannot be the same type of services the employee is paid to perform. A nonprofit’s bookkeeper can volunteer to serve meals at a fundraiser gala; the same bookkeeper cannot volunteer to reconcile the accounts on a Saturday.1U.S. Department of Labor. Fact Sheet 14A – Non-Profit Organizations and the Fair Labor Standards Act
Third, volunteers should serve on a part-time basis and cannot displace regular workers or take on what paid staff would otherwise do. A nonprofit that lays off its custodial team and then asks office employees to “volunteer” for cleaning shifts has stepped well over the line.
All three conditions matter independently. Meeting two out of three still produces compensable work time.
The “Same Type of Services” Test
The different-duties requirement is where most nonprofits stumble, because the line isn’t always obvious. The DOL looks at all the facts and circumstances, including whether the volunteer activity is closely related to the actual duties or responsibilities assigned to the employee in their paid role.2eCFR. 29 CFR Part 553 Subpart B – Volunteers Job titles don’t decide it. An IT director who volunteers to run audio-visual equipment at a charity auction is doing something that looks a lot like their day job, even if “event A/V” doesn’t appear in the job description.
The clearest cases involve a real change in the nature of the work. The DOL’s regulations for public agencies offer useful illustrations of the same principle: a police officer volunteering as a basketball referee for a city youth league, or a parks employee volunteering as a firefighter. Each activity sits in a different occupational category from the paid role. Nonprofits should apply the same logic. The closer the volunteer task looks to what the employee does nine-to-five, the higher the risk.
Special Events and Fundraisers
Annual galas, charity runs, and holiday drives create a gray zone. It’s tempting to assume that because an event is outside normal operations, any employee can pitch in. The DOL doesn’t see it that way. The test is still whether the volunteer activity matches the employee’s paid duties. A communications staffer setting up chairs and serving food is fine. That same staffer writing the event program, drafting the social media posts, and photographing the evening is doing exactly the work they’re paid for, on a different day.
Expense Reimbursements and Stipends
Reimbursing volunteers for out-of-pocket costs like mileage, parking, or supplies generally doesn’t jeopardize volunteer status. Those payments aren’t compensation; they put the volunteer back where they started financially. Trouble starts when payments go beyond actual expenses and begin to look like wages.
DOL guidance for private nonprofits states that the individual must serve “without contemplation or receipt of compensation.”1U.S. Department of Labor. Fact Sheet 14A – Non-Profit Organizations and the Fair Labor Standards Act A flat stipend that exceeds any reasonable estimate of actual expenses can be treated as compensation, which converts the volunteer into an employee entitled to minimum wage and overtime.
Even when the FLSA analysis holds up, the IRS may treat some volunteer payments as taxable income. Stipends, education awards, bonuses, and allowances received for volunteer service can be subject to income tax, and the organization typically issues a W-2 or Form 1099-MISC reporting the amount.3Internal Revenue Service. Volunteer Workers Pay Taxes Too Documented, receipt-backed reimbursements are the safest path.
One boundary worth noting: the DOL has said individuals generally cannot volunteer for commercial activities operated by a nonprofit, such as a gift shop. Even when the revenue funds the mission, the work looks like employment rather than charitable service.1U.S. Department of Labor.

What Happens If the Arrangement Fails the Test
When a nonprofit allows an employee to “volunteer” for duties that don’t clear the FLSA bar, every hour becomes compensable. The exposure builds quickly.
Back Pay and Overtime
The organization owes the employee for all misclassified hours at their regular rate. When those hours push the employee’s weekly total above 40, overtime is owed at one and a half times the regular rate for every hour over the threshold.4eCFR. 29 CFR Part 778 – Overtime Compensation A salaried program director working 38 paid hours a week who “volunteers” another 8 could be owed overtime on 6 of those hours every week, reaching back up to three years if the violation is found to be willful.
Liquidated Damages
On top of back wages, a court can award liquidated damages equal to the unpaid amount, effectively doubling the tab.5Office of the Law Revision Counsel. 29 USC 216 – Penalties Courts treat liquidated damages as the default unless the employer proves the violation was in good faith and based on reasonable grounds. For an organization operating on thin margins, that doubling can be crushing.
Civil and Criminal Penalties
The DOL can investigate and impose civil money penalties for repeated or willful minimum wage and overtime violations. As of 2025, the maximum penalty is $2,515 per violation, adjusted annually for inflation.6U.S. Department of Labor. Civil Money Penalty Inflation Adjustments Willful violations can also lead to criminal prosecution, with fines up to $10,000 and imprisonment of up to six months for a second offense.5Office of the Law Revision Counsel. 29 USC 216 – Penalties
Employment Tax Exposure
Reclassified hours generated wages, and wages carry employment tax obligations. The nonprofit becomes liable for its share of Social Security and Medicare taxes on the unpaid compensation, plus penalties and interest for failing to withhold the employee’s share.7Internal Revenue Service. Worker Classification 101 – Employee or Independent Contractor
Practical Steps That Protect the Arrangement
Most problems here come from sloppy boundaries rather than bad intent. A handful of habits make a meaningful difference.
Put it in writing. Have the employee sign a simple volunteer agreement confirming the service is freely given, unpaid, unrelated to their job duties, and undertaken without expectation of compensation or benefit. Specify the volunteer activities on the document itself.
Keep the paperwork separate. Track volunteer hours through the same sign-up process used for outside community volunteers, not through payroll or timekeeping. Mixing the two produces exactly the ambiguity that draws DOL scrutiny.
Train supervisors. Managers need to understand they cannot hand a volunteering employee a job-related task, even in passing. “While you’re here, could you update the donor spreadsheet?” turns a volunteer afternoon into compensable work.
Audit annually. Review volunteer roles against current job descriptions. A promotion can quietly change what an employee is now paid to do, meaning a fundraiser role that used to be safe volunteer territory may no longer be.
None of these steps is required on its own, but together they build a paper trail that shows the arrangement was genuine volunteering. When the DOL evaluates one of these situations, documented good faith carries weight.
A Note on Public Sector Employees
The framework above applies to private nonprofits. The FLSA contains a separate statutory exemption for volunteers at state and local government agencies under Section 3(e)(4), with detailed regulations at 29 CFR Part 553.2eCFR. 29 CFR Part 553 Subpart B – Volunteers The core principle is the same, but public agencies operate under a genuine statutory safe harbor, and their volunteers can also receive expense reimbursements, reasonable benefits, or a nominal fee without losing volunteer status.8eCFR. 29 CFR 553.106 – Payment of Expenses, Benefits, or Fees Private nonprofits are working from interpretive DOL guidance rather than that bright-line exemption, which is why documentation and clean lines between paid and volunteer work matter more, not less.
