Unpaid internships are lawful in the United States only when the intern is not an “employee” under the Fair Labor Standards Act. The controlling framework is the primary beneficiary test, which the Department of Labor and federal courts use to ask who benefits most from the arrangement. State laws may add stricter rules that favor the intern, so the federal answer is never the whole answer.
TL;DR:
- For for profit employers, courts weigh seven nonexclusive factors, including structured teaching, school integration, academic scheduling, duration, staff displacement, and expectations about compensation or future jobs.
- Academic credit and written unpaid agreements do not establish legality; replacing paid staff or assigning work without instruction weakens an employer’s case.
- State rules can exceed federal protections, so interns should check local requirements before accepting offers and multistate employers should follow the strictest applicable standard.
- Federal discrimination protections may depend on employee status or meaningful benefits, and filing deadlines are typically 180 or 300 days, depending on location.
- Interns can report wage concerns to the Wage and Hour Division or state labor departments; discrimination complaints go to the EEOC or state agencies.

How the primary beneficiary test works: the seven factors
The Fair Labor Standards Act (FLSA) requires covered employers to pay minimum wage and overtime to employees. Whether an intern counts as an employee turns on the “economic reality” of the relationship, not on the label an employer chooses. For-profit employers must pay interns unless the intern qualifies as a non-employee under the primary beneficiary test, as DOL Fact Sheet #71 explains. The central question is whether the internship primarily serves the intern’s educational development or the employer’s immediate business needs.
For years the Department of Labor used its own six-part test, which many federal courts rejected as too rigid. On January 5, 2018, the Department announced it would conform enforcement to appellate court rulings and apply the primary beneficiary test instead, and Field Assistance Bulletin No. 2018-2 rescinded the older guidance. The seven factors below are non-exhaustive, and no single one controls the outcome.
1. Expectation of compensation. If both sides understand the internship is unpaid, that points toward non-employee status. It does not settle the question, because an agreement to work for free cannot waive FLSA rights. Courts weigh it alongside the other factors, and an employer cannot create an exemption just by asking the intern to sign something.
2. Educational training. The more the internship resembles a classroom or clinical experience, the stronger the case. Think structured instruction, shadowing with explanation, feedback sessions and defined learning objectives. An intern who spends weeks filing, making coffee runs or entering data with no teaching component looks like an employee doing a job.
3. Connection to formal education. An internship integrated into a degree program, with faculty involvement or required coursework, supports unpaid status. A placement a student finds independently, with no link to the curriculum, weakens it.
4. Academic calendar. Does the internship track the school schedule, with accommodation for exams and breaks? An arrangement that fits around a semester looks educational. One that demands full-time hours during finals does not.
5. Duration. The internship should last only as long as the educational benefit continues. An unpaid placement that stretches for many months, long after the intern has learned what the role can teach, starts to resemble free labor.
6. Displacement of paid employees. If the intern complements the work of regular staff without replacing anyone, that favors the employer. If the intern performs tasks a paid worker would otherwise do, or if the business would have to hire someone when interns leave, courts are likely to see an employee.
7. Expectation of a paid job. The intern should understand that the internship does not guarantee a job at the end. This factor is subtle: an internship may lead to an offer without that being the entitlement or the point, but a standing promise of employment can tip the balance.
The DOL and courts treat the test as deliberately flexible and fact specific. Employers should not assume that calling a role an “internship” or offering academic credit automatically allows unpaid status. If an intern’s work is indistinguishable from that of regular employees, courts are likely to treat the intern as an employee entitled to pay. There is no safe-harbor formula: employers have to weigh the economic reality and avoid structuring internships to deliver immediate business value that displaces paid staff.
A quick example shows the weighing. A marketing agency brings in a junior student for a summer program with regular training sessions, a mentor and a final presentation, and the intern shadows client calls. That reads as primarily educational. Now picture the same agency assigning an unpaid intern a full client account because staffing is short. The business benefit dominates, and the arrangement is hard to defend.

State laws can be stricter: New York and California
The FLSA is a federal baseline, not a ceiling. It does not preempt state laws that offer greater protection or classify workers differently, and where state and federal rules differ, employers must follow the standard that is more favorable to the worker. DOL Fact Sheet #71 notes that state-level laws often impose requirements more favorable to interns than federal law does.
That is why a program that looks acceptable under the federal test can still create exposure at the state level. States may apply their own tests, weigh factors differently or enforce more aggressively. State rules may differ from the federal approach, so employers should check the applicable state requirements. State requirements vary, so check the rules in the relevant state.
New York. Employers in New York should check the current state requirements before relying on the federal test.
California. California may have state rules that differ from the federal test. Employers and interns should check the current requirements with the state labor agency.
I am describing these two states as representative examples. Details change as legislatures, agencies and courts act, so confirm the current rule with the state agency before relying on any summary, including this one.
The practical consequences cut across states:
- State-level requirements. State rules may differ from federal requirements, so employers and interns should check the relevant state labor agency’s guidance.
- Where to seek help. Interns can contact the federal Wage and Hour Division or check with their state labor department about applicable processes.
- Compliance by the strictest rule. Employers operating in several states should build one program that meets the most protective standard they face, rather than maintaining a patchwork.
For interns, the takeaway is to check your own state’s labor department website before accepting an unpaid offer. For employers, it is to treat the federal test as a minimum. Our guide to state labor agency resources, using Illinois as a model, shows what to look for when reviewing a state agency’s guidance.
When an unpaid internship is commonly lawful
The primary beneficiary test governs for-profit employers. Different rules apply in other settings, and most lawful unpaid arrangements fall into a few recognizable patterns.
Public agencies and nonprofits. Individuals can usually volunteer for public agencies and charitable nonprofits without compensation, because volunteering for civic, charitable or humanitarian purposes sits outside the FLSA’s employee definition when no compensation is expected. Rules for public agencies and nonprofits may differ from those for private-sector employers, so check the applicable requirements. Private-sector unpaid internships get closer scrutiny under the primary beneficiary test.
Academic credit. Credit can support the educational nature of a placement, particularly when a school supervises it and ties it to coursework. But credit alone does not turn unpaid work at a for-profit into a lawful internship. The question remains who benefits and whether the intern displaces staff.
Stipends and Federal Work-Study. Outside funding, whether a small stipend or a work-study arrangement, interacts with the analysis in different ways depending on who pays and why. How a stipend affects the analysis depends on the circumstances; it does not automatically authorize unpaid work at a for-profit employer.
Structures that tend to hold up share the same features:
- A defined educational program with learning objectives and a start and end date
- Close supervision by someone who teaches rather than merely assigns work
- No displacement of paid staff and no reliance on the intern to meet business deadlines
- A school connection, such as a faculty advisor or required reflection paper
A university hospital’s observation program for pre-med students, a nonprofit’s supervised policy research placement and a for-credit practicum run jointly with a college all fit this pattern. A for-profit startup that fills its operations team with unpaid “interns” generally does not.
Workplace protections interns keep
Being unpaid does not mean being unprotected. Several federal anti-discrimination statutes can cover interns:
- Title VII of the Civil Rights Act, which bars discrimination based on race, color, religion, sex and national origin
- The Americans with Disabilities Act (ADA), which bars disability discrimination
- The Age Discrimination in Employment Act (ADEA), which protects people aged 40 or older
- The Genetic Information Nondiscrimination Act (GINA), which protects against discrimination based on genetic information
Coverage often depends on whether the intern counts as an employee or applicant, or receives significant non-wage remuneration. EEOC guidance explains that an unpaid intern’s coverage under EEO statutes often turns on whether the intern receives “significant remuneration.” Examples include pensions, insurance, workers’ compensation coverage or professional certifications. Small incidental benefits, such as academic credit, usually have not been treated as significant by courts.
This matters because it can leave a truly unpaid intern in a gap. Someone who receives nothing of real value may have a harder time invoking Title VII or the ADA, while an intern who gets meaningful benefits, or who was misclassified and should have been an employee, may be covered. Whether an applicant is protected depends on the applicable law and circumstances. Because the lines are fact specific, interns who experience harassment or discrimination should not assume they have no recourse. State protections may differ, so check the applicable state law.
Time limits are strict. Federal law sets deadlines for filing a charge of discrimination with the EEOC, and the FTC’s discussion of these protections notes that charges are typically due within 180 or 300 days, depending on the state and local laws where the workplace is located. Waiting can forfeit a claim. If you believe you have been harassed or treated unfairly, write down what happened, keep copies of messages and contact the EEOC or your state fair employment agency promptly.
Checklist: can this internship lawfully be unpaid?
Both employers and interns can run through the factors as yes or no questions. Treat the answers as evidence, not a guarantee, because no formula makes an internship safely unpaid.
- Does the intern understand in writing that the role is unpaid, and does that match the actual arrangement?
- Does the internship provide training similar to what a school would offer, with learning objectives?
- Is it tied to a degree program, with a school advisor or credit?
- Does it follow the academic calendar, with flexibility for classes and exams?
- Does it end when the educational benefit ends, with a fixed duration?
- Would the work be done by a paid employee if the intern were not there?
- Is it clear that the internship does not guarantee a job?
- Does the employer gain no immediate business advantage from the intern’s work?
Any answer that comes out the wrong way is a signal to rethink the program, pay the intern or check the state rule.
Documents worth keeping:
- The written internship agreement and offer letter
- Any academic arrangement, such as credit confirmation or a faculty advisor’s letter
- A supervision plan naming who teaches and how often
- A comparison of intern tasks with the duties of paid roles, showing no displacement
- Time records and a log of learning activities
Employers should also revisit the program each cycle, since rules and risk change. If an intern is in practice covering what a paid worker used to do, pay them. For interns, the questions that matter most before saying yes are who the supervisor is, whether the school or program is involved and whether you will be asked to work unsupervised or cover shifts.
If something goes wrong: remedies and where to file
Wage and discrimination problems follow different tracks, and you may be able to use both.
Wage claims. The U.S. Department of Labor’s Wage and Hour Division (WHD) enforces the FLSA and takes complaints from workers who believe they were misclassified. State labor departments handle state-law wage claims, which can offer broader coverage or different remedies. For background on how wage-claim rights work, see our unpaid overtime guide.
Discrimination claims. The EEOC or a state fair employment agency takes charges of discrimination and harassment, subject to the filing deadlines above.
Remedies vary by case and are never guaranteed. Outcomes depend on the facts, the forum and the law of your state.
A short path to get started:
- Write down your dates, hours, tasks, supervisors and any promises made, while the details are fresh.
- Gather the agreement, emails, schedules, pay or stipend records and any messages about your work.
- Contact the WHD or your state labor department for a wage claim, or the EEOC or state fair employment agency for discrimination, and file promptly.
- Consider speaking with an employment lawyer, especially if the deadline is close or the facts are complicated.
Why we wrote this, and where to check us
Unpaid internship law is a good example of why that matters. The rules are real, the deadlines are short and a lot of people sign up for unpaid work without knowing the test that decides whether it is lawful.
Workplace Fairness began as the National Employee Rights Institute and later took its current name, linking the knowledge of employment rights attorneys with the work of non-legal organizations and people concerned about fairness at work. That history shapes how we write: plain language, no jargon and a steady push for stronger protections.
Still, read the primary sources linked throughout this article, because agencies update guidance and courts keep refining the test. If you have a specific dispute, contact the enforcement agency or an employment lawyer. General information is a starting point, not a substitute for advice on your facts.

FAQ
How long can you do an unpaid internship?
There is no fixed federal limit. Under the primary beneficiary test, duration is one factor: the internship should last only as long as the educational benefit continues. A long unpaid placement is harder to defend, so a defined end date matters.
Do unpaid internships violate labor laws?
Not necessarily. They are lawful when the intern is not an employee under the primary beneficiary test, as DOL Fact Sheet #71 describes. They violate wage laws when the intern is effectively an employee who was not paid.
How do I write an offer letter for an unpaid internship?
Say plainly that the role is unpaid, state the start and end dates and describe the learning objectives and supervision. Reference any school credit or advisor, and state that the internship does not guarantee a job. Check your state’s rules and have a lawyer review the template.
What are the benefits of an unpaid internship?
Done properly, an unpaid internship can offer structured learning, mentorship, exposure to a field and a connection to coursework. Those benefits are exactly what the educational-focus factors measure, so they only support unpaid status when they are real.
