Can I Legally Hire Interns or Volunteers at a Startup?

Yes, but the rules are stricter than most founders expect. The Fair Labor Standards Act (FLSA) sets clear limits on when interns can go unpaid and whether for-profit businesses can use volunteers at all. Getting it wrong can mean back wages, penalties, and IRS reclassification — so it's worth understanding the rules before you post that listing.

The FLSA requires that most workers receive at least minimum wage. Unpaid internships are a legal exception — but only when the internship primarily benefits the intern, not the business. The Department of Labor calls this the "primary beneficiary test," and it's the standard courts use to decide whether an unpaid intern should have been classified as an employee.

A useful way to think about it: if your intern is doing work your business needs done, that's employment. If they're learning skills that primarily serve their own education or career development, that's an internship. The line isn't always obvious, which is why the DOL uses a multi-factor test rather than a single rule.

No single factor is decisive. Courts weigh all 6 together, and an internship doesn't need to satisfy every one to qualify as unpaid. That said, the more factors point toward employer benefit, the more likely the intern is legally an employee.

• Training similar to an educational environment — the experience should mirror classroom or lab learning, not just on-the-job task completion
• Tied to formal education — internships connected to coursework, academic credit, or school oversight are more likely to qualify
• No displacement of regular employees — interns must supplement your workforce, not replace paid staff or cover work that would otherwise go to an employee
• No immediate advantage to the employer — the business shouldn't be gaining productive output it would otherwise pay for
• No expectation of a paid job — both parties need to understand upfront that the internship doesn't lead to guaranteed employment
• Mutual understanding that the internship is unpaid — any hint of promised compensation can trigger wage obligations

Generally, no. Under the FLSA, for-profit businesses cannot accept volunteers for work that would otherwise be done by paid employees. This catches a lot of founders off guard — especially when a friend or supporter offers to help out. Good intentions don't change the legal classification.

The DOL's Fact Sheet #14A makes the distinction clear: individuals can volunteer for public service, religious, or humanitarian organizations without compensation, but not for private, for-profit entities. If someone is doing work your business benefits from, the FLSA treats them as an employee — and that means minimum wage applies.

If your business is structured as a nonprofit, the rules are different. Bona fide volunteers who receive little or no compensation and work without expectation of pay are generally exempt from FLSA minimum wage requirements. For LLCs and corporations operating for profit, that exemption doesn't apply.

Misclassifying an intern or volunteer as unpaid can be expensive. If the DOL or a court determines the person was actually an employee, your business can be on the hook for back wages at the federal minimum wage rate, plus liquidated damages equal to the unpaid amount — effectively doubling what you owe.

On top of that, the IRS can reclassify the worker as an employee, which means your business owes back payroll taxes — including the employer's share of FICA taxes (6.2% Social Security and 1.45% Medicare) — plus interest and penalties. Willful violations of the FLSA can also carry civil penalties up to $1,000 per violation.

State labor agencies can pile on additional penalties beyond what the DOL assesses at the federal level. Some states have stricter intern classification rules than the FLSA — Massachusetts, for example, generally requires payment for interns who don't receive academic credit unless a narrow trainee exemption applies. Talk to a local employment attorney before launching a program if you're unsure how your state's rules interact with federal law.

A well-structured internship program protects your business and actually attracts better candidates. The documentation step is the one most founders skip — and it's the one that matters most if a dispute comes up later.

Define learning objectives in writing

Before the internship starts, document what the intern will learn and how it connects to their academic or career development. This isn't just good practice — it's evidence that the internship is structured around the intern's benefit, not your business's needs. Keep a copy of this document in your records.

Use a written internship agreement

The agreement should confirm that the internship is unpaid, that no job is guaranteed at the end, and that both parties understand the arrangement. Any ambiguity about compensation — even an offhand comment about future pay — can be used to argue an employment relationship existed. Get it in writing before day one.

Provide structured supervision and training

Assign a mentor, schedule regular check-ins, and give the intern tasks that build skills — not tasks that just clear your to-do list. Interns should shadow employees, work on defined projects, and receive feedback. If the intern is doing the same routine work as your paid staff, that's a red flag under the primary beneficiary test.

Keep the duration tied to the learning period

Internships should last only as long as the educational experience requires — typically one semester. Open-ended arrangements that extend indefinitely look more like employment than education. Set a clear end date at the start and stick to it.

Paid internships are often the cleaner option for for-profit startups. They eliminate the classification risk entirely, expand your candidate pool to students who can't afford to work for free, and tend to attract more motivated applicants. The legal ambiguity of unpaid arrangements isn't worth the exposure for most early-stage businesses.

If budget is the constraint, there are other ways to get help without the compliance risk. Part-time employees give you flexibility without the internship classification questions. Work-study partnerships with local colleges can bring in students whose wages are partially subsidized. Project-based freelancers are another option — they're independent contractors, which comes with its own classification rules, but the FLSA unpaid internship framework doesn't apply.
