Internship Offer Letter Template for Small Business
Six free internship offer letter templates: paid, unpaid or for-credit, summer, IP and confidentiality, conversion, and extension. DOCX, no signup.
The first internship offer letter I ever sent was a standard offer letter with the word intern typed over the job title and the salary line deleted. It took about four minutes. It was also wrong in three separate ways, and I only found that out later when a founder friend forwarded me a demand letter he had received over an internship that looked exactly like mine.
An internship offer letter is not a shortened employment offer. It carries a wage-and-hour question that a normal offer letter never has to answer, a fixed end date that fights with at-will language, an academic relationship that may involve a third party, and an intellectual property (IP) problem created by someone who will hold your source code for eleven weeks and then go back to campus.
At FirstHR, we build onboarding software for small businesses that hire without a dedicated HR person, and interns are usually the first hires those companies make outside their own network. The six templates below cover the paid case, the unpaid or for-credit case, the summer cohort, the confidentiality and IP agreement, the conversion offer, and the extension letter.

Paid or Unpaid: Settle This First
Decide whether the internship is paid before you write a single line of the letter, because the two documents are not variations on a theme. They rest on different legal footing and share almost no clauses. A paid intern is an employee. An unpaid intern, if the arrangement holds up, is not.
A paid intern is a non-exempt employee under the Fair Labor Standards Act (FLSA). That means at least the federal minimum wage of $7.25 per hour under 29 U.S.C. 206, or the higher state or local rate where the intern works, plus overtime at time and a half after 40 hours in a workweek.
Employing a paid intern also means timekeeping, payroll registration in the state where the intern works, and inclusion in your workers compensation coverage.
An unpaid intern is outside the FLSA only if the Department of Labor primary beneficiary test favors the intern. That is a fact-specific analysis, not a form you fill in. Getting the classification wrong exposes you to back wages and liquidated damages.
A wage claim can reach back two years under the FLSA, or three for a willful violation, per 29 U.S.C. 255, and some states allow longer windows.
| Question | Paid internship | Unpaid or for-credit internship |
|---|---|---|
| Is the intern an employee? | Yes, non-exempt under the FLSA | No, if the primary beneficiary test holds |
| Minimum wage and overtime | Required | Not required if the test holds |
| Timekeeping | Required for every hour worked | Track hours anyway as evidence of the schedule |
| Form I-9 | Section 1 by day one, Section 2 within three business days | Not required, no employment relationship |
| Payroll tax and W-2 | Yes | No |
| Workers compensation | Covered as an employee | Check your policy, coverage often does not extend |
| Unemployment insurance | Wages are reportable | Not applicable |
| School learning agreement | Optional | Effectively necessary |
| Realistic fit for a small for-profit team | Almost always the right answer | Rare, and hard to defend |
The FLSA Primary Beneficiary Test, Factor by Factor
The primary beneficiary test asks a single question: in the economic reality of this relationship, who gets the main benefit, the intern or the company? The Department of Labor adopted the test in Fact Sheet #71, replacing the older six-part test that treated every element as mandatory.
Seven factors go into the analysis. Fact Sheet #71 notes that courts have described the primary beneficiary test as flexible and that no single factor is determinative, which cuts both ways. You cannot fail one factor and be automatically out, and you cannot pass one factor and be safe.
Read those factors as a description of a teaching relationship, because that is what they describe. The unpaid internship the FLSA contemplates looks like a clinical rotation or a practicum, with a curriculum, a supervisor whose job includes instruction, and a school on the other end of it. It does not look like an extra pair of hands in August.
Can a For-Profit Small Business Realistically Run an Unpaid Internship?
Honestly, almost never. The unpaid route is legally available to for-profit employers, but the structure the test requires is one that small companies are the least equipped to build, and the factors that most often decide a case are exactly the ones a small team fails. Plan on paying.
The problem is not that small businesses are careless. It is that the test rewards institutional infrastructure. Training that resembles an educational environment costs supervisor hours. A tie to a formal education program requires a relationship with a school. Accommodating the academic calendar means giving up schedule control. Ask yourself these five questions before you go anywhere near an unpaid arrangement.
State law narrows the door further. The New York State Department of Labor evaluates unpaid interns at for-profit businesses against eleven criteria, six drawn from the older federal test and five of its own. It treats them as conditions: no employment relationship exists only if all eleven are met.
One of the eleven criteria requires written notice, given before the internship starts, that the intern will receive no wages and is not an employee for minimum wage purposes.
Anti-discrimination law follows a separate track. California, New York, Oregon, and the District of Columbia extend harassment and discrimination protections to unpaid interns, and Illinois covers unpaid interns for sexual harassment under its Human Rights Act. The unpaid label does not remove those obligations.
Academic Credit Is Not a Payment Method
Academic credit does not make an internship lawfully unpaid. It is one factor of seven, and it is awarded by the school rather than by you. The student typically pays tuition for those credits, which means the credit arrangement transfers money away from the intern, not toward them.
Credit does real work in the analysis. It supports factor three, the tie to a formal education program, and it usually brings factor four along with it, because credit-bearing internships track the academic calendar. What credit cannot do is fix factor six. If the intern is doing work you would otherwise pay someone to do, no registrar can convert that into training.
If you do run a for-credit internship, get the school paperwork into the file. Ask for the learning agreement, name the faculty sponsor in the offer letter, and write the learning objectives down before the internship starts rather than reconstructing them afterward. Template 2 below has fields for all of it.
Six Internship Offer Letter and Agreement Templates
Each template covers a different point in the internship lifecycle. Download all six as one file, or take them individually. Every bracketed field needs to be filled in, and the warning block inside the unpaid template needs to be deleted only after you have actually done the analysis it describes.
Template 1: Paid Internship Offer Letter
The default choice for a for-profit small business. Includes the non-exempt classification, overtime notice, timekeeping instructions, at-will language that survives the scheduled end date, and an explicit statement that no full-time role is promised.
Template 2: Unpaid or For-Credit Internship Offer Letter
Use only after the primary beneficiary analysis supports it. Documents the school connection, the faculty sponsor, written learning objectives, the no-compensation understanding, and a signed acknowledgment from the intern. Leaves room for a school countersignature.
Template 3: Summer Internship Offer Letter
Built for a fixed-length seasonal cohort. Adds program structure by week, a mid-point review, equipment return, an optional housing stipend line, and the confidentiality agreement as a contingency of the offer.
Template 4: Internship Agreement With Confidentiality and IP Assignment
The separate signed agreement that the offer letter references. Covers confidential information, work product ownership, a coursework and personal project carve-out, portfolio permission, the statutory whistleblower notice, and return of company property.
Template 5: Intern to Full-Time Conversion Offer Letter
A full offer letter for an intern you are hiring permanently. Restates salary, FLSA classification, and benefits eligibility, confirms the internship agreement stays in force, and answers the service-date question that trips people up on accruals.
Template 6: Internship Extension Letter
A short letter for extending an internship past its original end date. States the new end date, the reason, the schedule, the rate, and a list of the things the extension does not change, including at-will status and the absence of any job guarantee.
Each template already builds in the clauses that set an internship letter apart from a standard offer letter.
Six Clauses a Standard Offer Letter Does Not Have
An internship letter needs six clauses that a normal offer letter lacks. They exist because internships have an end date, a school on the other side, a candidate who may be under 18, and a short stay that still exposes your work. Skipping any of them is where the trouble starts.
The ordering matters as much as the content. Put the dates and schedule near the top, because that is the section the intern actually reads and the section their school will ask about. Put the at-will and no-guarantee language in its own labeled block so nobody can claim they missed it in a paragraph about benefits.
At-Will Language and a Fixed End Date in the Same Letter
A scheduled end date and at-will employment are not contradictory, but only if you say so explicitly. Left alone, a sentence saying the internship runs from June 2 through August 15 reads like a promise of eleven weeks of work, which is exactly the implied contract that at-will employment is supposed to prevent.
The fix is three sentences in one labeled section. Call the date a scheduled end date. State that either party may end the internship at any time, with or without cause or advance notice, before that date. State that nothing in the letter creates a contract of employment for a specific period or entitles the intern to a position afterward.
| Phrase in the letter | Problem it creates | Replacement |
|---|---|---|
| The internship will run from June 2 to August 15 | Reads as a guaranteed eleven weeks of work | Scheduled end date: August 15. Either party may end the internship earlier. |
| You will be considered for a full-time role at the end | Sets an expectation of a job and undercuts factor seven on an unpaid internship | Conversion decisions are made at the company’s discretion and no position is promised. |
| Your summer salary will be $6,000 | A lump sum implies a fixed term and hides the hourly rate a non-exempt worker needs | $[X] per hour, paid bi-weekly, non-exempt, overtime after 40 hours. |
| We expect you to be available whenever the team needs you | Open-ended availability invites unrecorded off-the-clock hours | Scheduled hours are [X] per week. All hours must be recorded. Overtime requires prior approval. |
| This is a training position, so hours are flexible | Suggests hours worked are not compensable time | All time worked is paid time. Report every hour you work. |
An intern who is a paid employee is non-exempt, however impressive the title. The FLSA has no intern exemption, and a student in a temporary learning role will not meet the salary and duties tests behind exempt classification. Applicant tracking is coming soon to FirstHR, and the classification decision belongs in the offer letter regardless of how the candidate reached you.
Confidentiality and IP Assignment for Interns
Interns need a signed confidentiality and IP assignment agreement before their first day, and the offer letter should list it as a contingency. Interns see customer data, prototypes, and unreleased work on a compressed timeline, then leave with all of it in their heads and often in a portfolio draft.
Two clauses in a standard employee agreement need editing for interns. The first is the assignment scope. A boilerplate clause that assigns everything the person creates during the relationship will sweep in class projects and personal work, which is unfair, unenforceable in several states, and a fast way to lose a good candidate. Carve out work the intern creates on their own time and equipment without company confidential information.
The second is the portfolio question. Design, marketing, and engineering interns will want to show their work when they apply for jobs. Decide in advance whether redacted portfolio use is permitted and who approves specific materials, then write the answer into the agreement instead of handling it by email in November.
Keep the confidentiality obligation alive after the internship ends, and make the property return concrete. Name the laptop, the badge, and the accounts, and set the return for the last day rather than sometime after it. An intern who has already flown home is a hard person to collect a laptop from.
Internship Contract or Offer Letter: Which You Need
You need both: an offer letter and a separate signed agreement, rather than a single internship contract. The offer letter sets the terms and is written so it does not become a promise of work for a fixed period. Template 4 is the binding half, covering confidentiality, work product, portfolio use, and return of property.
Send both together and make the signature on the agreement a condition of the offer. If a school or a parent asks to see the contract, that pair is the answer: the letter carries the dates, hours, and pay, and the agreement carries the obligations that outlast the last day.
The Conversion-to-Full-Time Clause
The conversion clause in an internship offer letter should describe the process and promise nothing. Say when conversion decisions are made, who makes them, and that any offer will arrive in a separate written letter. Anything stronger creates an expectation that hurts you legally on an unpaid internship and commercially on a paid one.
Conversion is a major reason small companies run internships, and the numbers show it works. According to the National Association of Colleges and Employers 2026 Internship and Co-op Report, employers converted 63.1 percent of their 2024 to 2025 interns into full-time hires, the highest rate in five years, and the acceptance rate on those offers reached 88.3 percent. An intern who accepts already knows the work, the tools, and the team.
When you do convert, send a real offer letter rather than an email saying congratulations. Template 5 covers the fields that get forgotten: the FLSA classification for the new role, benefits eligibility dates, and whether internship service counts toward accruals and plan eligibility. Answer the service-date question explicitly, because the intern will ask about their paid time off balance in week two.
| Conversion step | Timing | Document |
|---|---|---|
| Set the conversion criteria with the supervisor | Before the internship starts | Internal note, not the offer letter |
| Mid-internship review | Roughly the halfway point | Written review shared with the intern |
| Decide and check budget | Two to three weeks before the end date | Internal approval |
| Send the full-time offer | At least two weeks before the last day | Conversion offer letter, Template 5 |
| Collect signature and new-hire paperwork | Before the internship end date | Signed offer, updated agreements |
| No offer: close it cleanly | Before the last day | Exit conversation and feedback |
If you are not converting, say so before the last day and give real feedback. Interns talk to their classmates and to their career office, and a silent ending costs you candidates from that school. A short exit conversation using intern exit interview questions gets you honest feedback about your program while the details are still fresh.
Paperwork and Payroll Setup for a Paid Intern
A paid intern is an employee, so they get the full new-hire paperwork stack. Form I-9 has two deadlines: the intern completes Section 1 on or before the first day, and you complete Section 2 within three business days of the start, per the U.S. Citizenship and Immigration Services Handbook for Employers (M-274).
Beyond the I-9 come the federal and state withholding forms, direct deposit, your handbook acknowledgment, and any state-specific wage notice. Register for payroll in the state where the intern physically works, which for a remote intern is the state they are sitting in, not your headquarters.
Two items are easy to miss. Confirm that your workers compensation policy covers interns, paid or unpaid, before the start date. And check your state youth employment rules if the intern is under 18, since hour limits, prohibited occupations, and work permits vary by state and by age. Applicant tracking is coming soon to FirstHR, and the onboarding steps that follow acceptance run in the platform today.
Interns are not contractors. Issuing a 1099 to a summer intern who works your hours, on your equipment, under your supervision is worker misclassification with a different label, and it can draw a state audit.
If the working relationship looks like the one in the paid-internship templates, the person is an employee. The distinction between an employee and an independent contractor turns on control, not on how long the engagement lasts.
Frequently Asked Questions
Do you have to pay interns?
In most cases at a for-profit company, yes. When an intern counts as an employee under the Fair Labor Standards Act, the company owes at least the federal minimum wage of $7.25 per hour, or whichever state or local rate is higher, and overtime after 40 hours in a workweek. The exception is narrow. The Department of Labor primary beneficiary test asks whether the intern or the business gets the main benefit from the arrangement, and it weighs seven factors, among them academic credit, structured training, and whether the intern takes over work that paid staff would otherwise do. Most small business internships fail several of those factors, so the intern is an employee and has to be paid.
What is the FLSA primary beneficiary test?
The primary beneficiary test is how the Department of Labor, in Fact Sheet #71, decides whether an intern at a for-profit employer is really an employee who is owed minimum wage and overtime. It looks at the economic reality of the relationship through seven factors: whether both sides expect no pay, whether the training resembles an educational setting, whether the internship is tied to a formal education program, whether it accommodates the intern’s school commitments, whether its length is limited to the period of beneficial learning, whether the intern’s work complements rather than displaces paid employees, and whether both sides understand that no paid job is promised at the end. According to Fact Sheet #71, courts have called the test flexible, and no single factor decides the outcome.
Does giving academic credit make an internship legally unpaid?
No. Academic credit is only one of the seven factors, not a waiver of wage law. The school awards the credit, not the employer, and it costs the student tuition rather than paying them. Credit strengthens factors three and four of the primary beneficiary test, but it does nothing for the factors that usually decide the case: whether the intern displaces paid employees, whether the training resembles an educational environment, and whether the duration is limited to beneficial learning. An unpaid intern doing production work for a for-profit business is an employee under the FLSA whether or not a registrar recorded three credit hours.
What should an internship offer letter include?
An internship offer letter should include the title, department, named supervisor, work location, start date, scheduled end date, weekly hours and schedule, pay rate with FLSA classification for a paid internship, timekeeping instructions, which benefits apply, an at-will statement that survives the stated end date, a clear statement that no full-time job is promised, contingencies such as Form I-9 verification and a signed confidentiality and IP agreement, an acceptance deadline, and signature lines. If the intern is under 18, add a parent or guardian signature line. Unpaid or for-credit internships add the school name, course, credits, faculty sponsor, written learning objectives, and a signed acknowledgment that there is no expectation of compensation.
Is an internship offer letter a contract?
A well-drafted internship offer letter is not an employment contract, though a sloppy one can start to look like one. The usual culprit is the end date. A letter saying the internship runs from June through August can be read as a promise of work for the whole stretch, which is the opposite of at-will employment. Calling the date a scheduled end date, saying either side can end the internship earlier with or without cause, and stating that the letter creates no contract of employment for a set period keeps the letter on the right side of that line. The separate internship agreement on confidentiality and IP is different: it is a real contract and is meant to be one.
Can interns sign an NDA and an IP assignment agreement?
Yes, and they should. An intern can see customer data, pricing, prototypes, and unreleased work within a few weeks and then walk out with it in their head, so the exposure is real even though the stay is short. Put the signed agreement in the offer as a condition, so it is in place before the first day. Draft it with two intern-specific points in mind. First, exclude coursework, class projects, and anything the intern builds on personal time with their own equipment, or the assignment clause will claim material the intern needs for school. Second, add the Defend Trade Secrets Act whistleblower immunity notice, because leaving it out limits what the employer can recover in a later trade secret case.
How do you convert an intern to a full-time employee?
Send a separate full-time offer letter rather than amending the internship letter. The new letter restates the job title, manager, salary, FLSA classification, benefits eligibility, and at-will status, and it confirms that the confidentiality and IP agreement the intern signed at the start still applies. Decide whether internship service counts toward paid time off accrual, retirement plan eligibility, or service awards, and write the answer down. The odds favor you: the National Association of Colleges and Employers 2026 Internship and Co-op Report found a conversion rate of 63.1 percent for 2024 to 2025 interns, and 88.3 percent of the full-time offers made to them were accepted.
Can you extend an internship past the original end date?
Yes. A short written extension letter does the job: it gives the new end date, the reason, the schedule, the pay rate, and a line confirming that the confidentiality and IP agreement is still in effect. Restate the at-will language and the point that no full-time position is promised. Get it out before the original end date passes, so the intern is never working on terms nobody has documented. For a paid internship, extending is straightforward. An unpaid or for-credit internship carries more risk, because the primary beneficiary test asks whether the duration is limited to the period of beneficial learning, and an internship that outlasts the learning is hard to defend as unpaid.
