The short answer to the question many Houston employers are quietly asking: unpaid internships are not automatically illegal. But a substantial number of Houston employers—particularly outside the energy majors and BigLaw offices with full HR infrastructure—are running programs that would fail a federal audit today. The DOL’s Wage and Hour Division has a regional enforcement office in Houston. Wage-and-hour claims filed here aren’t abstracted out to Washington; they’re worked locally. They result in back pay orders, civil money penalties, and reputational damage that can be genuinely serious for a mid-size firm.
This piece walks through the full picture: the legal test for unpaid internships, where Houston employers typically fail it, what the market actually pays across energy, legal, and healthcare sectors in 2026, the payroll classification mistake that trips up small businesses every summer, and what a defensible Texas intern offer letter needs to include.
The Legal Framework: The DOL’s Primary Beneficiary Test in Plain English
The controlling federal framework comes from DOL Wage and Hour Division Fact Sheet #71, which codifies the “primary beneficiary test.” It’s a seven-factor analysis that asks one underlying question: who benefits more from this arrangement, the intern or the employer? If the honest answer is the employer, the intern is an employee and must be paid at least minimum wage under the Fair Labor Standards Act.
No single factor is determinative. You can fail one and still run a lawful unpaid program. You can technically pass all seven and still face scrutiny if the overall picture looks like free labor. Here’s what each factor actually means in practice.
Factor 1 asks whether both parties clearly understand there’s no expectation of compensation. Both the employer and the intern must understand this, and they must document it. Ambiguity here isn’t a minor gap—it’s a direct failure of the test’s foundational element. An offer letter that leaves compensation open, or a verbal understanding that drifts as the summer goes on, will undermine a compliance defense.
Factor 2 examines whether the training resembles what an educational institution would provide. The intern’s work should mirror coursework: structured observation, supervised skill-building, exposure to professional practice. If your summer intern is doing the same thing your junior employees do—unobserved and unstructured—this factor becomes a serious problem. An intern filing a wage claim with a job description that’s indistinguishable from an entry-level posting will have a strong argument.
Factor 3 concerns whether the internship connects to a formal education program. The intern should be enrolled in school and ideally receiving academic credit. But receiving credit doesn’t make an unpaid arrangement lawful. The DOL has said this explicitly. Universities that approve academic credit are applying academic standards, not legal ones—and a registrar’s approval is a red herring in a wage-and-hour investigation. I’d flag it any time an employer mentions it as though it settles the question.
Factor 4: does the internship accommodate the intern’s academic commitments? Scheduling and workload should reflect that the intern is first and foremost a student. An intern working 50-hour weeks during the fall semester while completing coursework is quietly generating evidence against the employer.
Factor 5 asks whether the internship duration matches the period of beneficial learning. Programs that track to a defined academic term score better here than open-ended arrangements. An internship that extends indefinitely—or gets renewed quarter after quarter because the work is still useful—suggests the learning objective passed and the employment objective took over.
Factor 6: does the intern’s work add to, rather than replace, the work of paid employees? This is often the most directly determinative factor in Houston disputes. The intern should be learning alongside your workforce, not filling a headcount gap. If you’d otherwise hire a temp or extend an existing employee’s hours to cover the work your intern is doing, the arrangement likely fails here. A lot of energy services companies, law firms, and medical institutions run into trouble this way—sometimes because a supervisor just gets busy and starts leaning on whoever’s available. The legal analysis doesn’t care about intent.
Factor 7 concerns whether both parties understand there’s no guarantee of a job afterward. It’s often misread as simply requiring a disclaimer in offer documents. What it’s really asking is whether the internship functions as a working audition—an unpaid tryout for a role you intend to fill with that person. If your intern is doing the work of a potential hire and you’re evaluating them for employment, that’s probationary employment, not an internship. The energy company that runs through a summer cohort and converts top performers to full-time offers is operating a working-interview program. Call it what it is.
On Texas law specifically: The Texas Workforce Commission enforces the Texas Payday Law, and Texas Labor Code §62.051 mirrors the federal minimum wage. The state floor has always tracked the federal floor. Texas imposes no additional intern-specific requirements beyond FLSA—the TWC’s role here is primarily unemployment insurance administration and wage claim processing. Houston cannot set its own minimum wage; state law preempts local wage ordinances. The substantive legal standard for intern classification is federal.
Where Houston Employers Actually Fail the Test
Three scenarios come up repeatedly in Houston’s employment law world, and they appear regularly in our business & professional coverage.
The Energy Corridor oilfield services company. A mid-size completion services firm takes on a petroleum engineering junior from UH or Texas A&M. The student is bright and develops genuine technical ability fast. By week four, they’re generating production reports that go directly into client deliverables. The supervisor is too busy to do much mentoring. The intern has replaced what would otherwise require a junior engineer or extended hours from someone already stretched thin. This arrangement fails Factor 6 (displacement), Factor 2 (no structured training), and Factor 5 (the internship is no longer bounded by a learning arc; it has become indefinite production work). Factor 7 is also shaky because the firm typically converts strong summer interns to full-time offers. The university credit doesn’t change any of this. It never has.
Then there’s the downtown law firm using an undergraduate as paralegal coverage. A litigation boutique loses a paralegal in April and covers with an unpaid pre-law undergraduate until a replacement is hired. The intern organizes case files, drafts discovery logs, and calendars deadlines—work a paid paralegal would otherwise do. Nearly every factor fails. This isn’t an internship. It’s unpaid paralegal employment. And depending on the work involved, it may create unauthorized practice issues that add liability well beyond the wage-and-hour problem. Word travels in a small legal community.
The TMC research hospital scenario follows a similar logic but in a different register. A major Texas Medical Center institution assigns a pre-med undergraduate to data entry for an ongoing clinical study—transcribing patient survey responses into a database. A paid research coordinator would otherwise do this. The intern gains minimal educational value from work that any reasonably literate person could perform. Factor 2 fails, Factor 6 fails, Factor 5 fails. The fact that it’s a prestigious research institution and the student is gaining “resume experience” doesn’t change the FLSA analysis. A student doing data entry isn’t legally distinguishable from any other unpaid data entry operator.
One point worth repeating across all three: academic credit is not a safe harbor. The DOL has never recognized it as one. Employers who rely on this are running an unsupported compliance position they would struggle to defend in an investigation.
What Houston Employers Are Actually Paying Summer Interns in 2026
Market pressure does more enforcement work than the DOL in several sectors. At the top of the Houston market, compensation is strong enough that unpaid programs simply aren’t viable—talent goes elsewhere, and the firm trying to run an unpaid arrangement loses access to the candidate pool entirely. Probably deserves to.
Energy majors like ExxonMobil, Shell, Chevron Phillips Chemical, and LyondellBasell typically pay undergraduate engineering interns $25 to $35 per hour, with petroleum, chemical, and mechanical engineering disciplines at the higher end. ExxonMobil and Shell both offer structured programs with housing stipends for out-of-state interns—typically $1,000 to $2,000 on top of hourly compensation. One thing employers frequently get wrong about those stipends: housing allowances paid as cash are taxable wages in almost all cases. The narrow IRS exclusion for employer-provided housing doesn’t apply to cash payments, regardless of how the offer letter labels them.
Oilfield services firms—Halliburton, SLB, Baker Hughes—pay undergraduate technical interns in the $22 to $30 range, with some variation by discipline. These firms typically don’t offer separate housing stipends but may provide relocation assistance for interns coming to Houston from out of state.
Midstream companies like Enterprise Products Partners and Kinder Morgan pay roughly $20 to $28 per hour depending on discipline—finance and accounting interns at the lower end, engineering at the upper. These programs are generally well-run and competitive enough to attract strong candidates. Smaller independents and E&P companies tend to come in at $18 to $25 per hour, sometimes offering flat stipends rather than hourly rates. It’s not a coincidence that firms paying below market are also more likely to be running informal intern arrangements without documentation.
BigLaw Houston offices—Vinson & Elkins, Baker Botts, Bracewell, Norton Rose Fulbright—compete nationally for law school summer associates. Houston offices of firms at or near the Milbank scale, currently $4,327 per week for 2025, pay accordingly. Nobody at V&E is agonizing over the primary beneficiary test. These are W-2 arrangements with full compliance infrastructure, and they function as a useful reference point precisely because the classification question never comes up.
Mid-size Houston firms below the Milbank scale typically pay law school summer associates $1,500 to $2,500 per week. This is where small plaintiff’s shops and boutique firms operate, and the variation is wide. Some pay modest but legitimate hourly wages. Others still run “for credit” unpaid arrangements for law students, rationalizing it as educational exposure. Given the Milbank market as a comparison point and the accessibility of a TWC wage claim or DOL complaint as an enforcement mechanism, these arrangements represent real legal and reputational risk for firms that haven’t invested in compliance infrastructure. Employers grappling with the broader overhead of running a lean Houston operation may find useful context in what Houston businesses actually pay for a PEO, since payroll administration for seasonal workers is one of the functions those arrangements typically cover.
Undergraduate pre-law interns at law firms are a distinct and frequently mishandled category. They aren’t law students; they can’t bill legal work. If they’re performing paralegal-equivalent work, they need to be paid. No exceptions. Mid-size Houston firms typically pay these interns $15 to $20 per hour when they’re paying them at all. The ones who aren’t paying them are making a compliance bet they shouldn’t be making.
At the Texas Medical Center, undergraduate research interns typically receive stipends rather than hourly wages—flat amounts for 10-week summer programs ranging from roughly $3,000 to $5,000 depending on the lab, funding source, and whether the position is NIH-funded or institutionally funded. Clinical programs within accredited medical or nursing education sit in a different legal category under a specific FLSA exemption. But that exemption is narrow and doesn’t cover general pre-med research work. The tax treatment of these stipends also matters: if the intern performs services in exchange for the stipend—running experiments, collecting data, assisting researchers—it’s taxable compensation subject to withholding. It’s not a scholarship excludable under IRC §117. Institutions issuing these without W-2s are creating compliance exposure and a confusing tax situation for students who are just trying to pay rent.
Texas Minimum Wage, Texas Income Tax, and What Employers Actually Owe
Texas minimum wage is set by Texas Labor Code §62.051 at the federal floor—currently $7.25 per hour. Verify whether federal minimum wage legislation has altered this figure before 2026 summer programs begin. In practical terms, the legal floor is almost irrelevant to competitive hiring in any of the sectors described here. But it matters for one reason: an intern who should have been paid minimum wage as an employee is owed back pay at the applicable rate, plus potentially liquidated damages equal to the same amount under FLSA. A disputed intern classification across a summer cohort can generate several thousand dollars in back-pay exposure even at $7.25 per hour across a 10-week program. That’s before legal fees.
Texas has no state income tax, which simplifies the withholding picture considerably. No Texas income tax withholding, no state equivalent of the W-4, no state income tax return for employees to file. Employers handle federal income tax withholding only. The TWC still administers state unemployment insurance, though—employees, including interns properly classified as employees, are covered for TWC reporting purposes. Both FUTA and SUTA apply.
Several large Houston employers—Memorial Hermann, Houston Methodist, the energy majors—maintain internal pay floors that substantially exceed the federal minimum. These internal standards matter far more operationally than the legal floor. An employer that has set a $15 per hour minimum across the organization shouldn’t be circumventing that floor by offering unpaid internships. If your own pay policy would prohibit it for regular staff, that’s telling you something worth listening to.
W-2 or 1099: The Payroll Classification Error That Follows Small Businesses Into Audit Season
This is the most common practical compliance mistake Houston small businesses make with paid interns. It’s entirely avoidable, and yet it comes up repeatedly in conversations with small firm owners who genuinely thought they were doing it right.
A summer intern who is paid for work performed is an employee. The economic reality of the relationship—not what the offer letter calls it—determines classification under both IRS guidance and DOL standards. An intern who shows up at your office, performs work under your direction, uses your equipment, and receives payment for their time is an employee. Issuing them a 1099-NEC at year end is wrong. It creates self-employment tax exposure for the intern, who likely doesn’t understand why they suddenly owe 15.3% in FICA on their own. It also signals to the IRS that the employer either didn’t understand their obligations or chose to avoid them.
The correct treatment for a paid intern: W-2 employment. Withhold federal income tax using the intern’s W-4 election. Withhold the employee share of FICA—6.2% Social Security, 1.45% Medicare—and pay the employer match. File quarterly Form 941. Issue a W-2 by January 31. No state income tax withholding in Texas. TWC unemployment insurance applies. This isn’t complicated. It isn’t optional.
Stipend-only arrangements don’t escape this analysis if the stipend compensates for services. A “monthly stipend” paid to an intern who performs work is wages—not a fellowship, and not something you run through accounts payable. The label doesn’t change the substance. A research institution that issues a “research stipend” without withholding is making the same mistake as the law firm issuing a 1099 to an unpaid paralegal intern: applying the wrong classification to avoid administrative burden on the business side.
Housing allowances and meal stipends paid as cash are taxable wages in virtually all cases. They belong in W-2 wages and are subject to FICA. Employers who gross up these allowances to cover tax costs are doing their interns a genuine service. Employers who pay them off payroll are creating liability. An intern who discovers they owe unexpected taxes on a housing stipend they thought was non-taxable may decide a TWC wage complaint is a reasonable response. They wouldn’t be wrong.
What Must Go Into a Texas Intern Offer Letter in 2026
The offer letter either documents your compliance position or undermines it. Most “intern offer letters” circulating at Houston small businesses are generic templates downloaded from the internet or, worse, verbal agreements. Neither is adequate. Verbal-only arrangements are especially hard to defend when a former intern files a claim six months later with a different recollection of what was discussed.
Compensation terms belong first. State the hourly rate or stipend amount, payment frequency, and method. For unpaid arrangements, state explicitly that no compensation will be paid and that the intern understands and agrees to this. Don’t leave room for ambiguity about whether payment might materialize later or whether the intern will be considered for a paid position within the term. This goes directly to Factor 1.
The internship must have a defined end date tied to an educational calendar or academic term. Open-ended arrangements look like employment, not an educational program. An internship ending August 15 signals educational purpose. One running “until we no longer need the coverage” signals something else entirely. Factor 5.
Describe duties in terms of what the intern will learn, not just what they’ll do. If the description reads like a job posting—“manage spreadsheet data,” “handle incoming calls”—rewrite it. An improved version: “Intern will observe monthly financial close processes by assisting the accounting team with ledger reconciliation, learning how the firm’s general ledger is structured and how close procedures work.” If you can’t articulate what the intern will learn from the work, that’s a sign the work isn’t appropriate for an unpaid internship. Factors 2 and 3.
Name the specific person responsible for the intern’s training and oversight. This establishes accountability within the firm and is relevant to Factor 2. If no one is designated to mentor the intern, the intern is almost certainly doing independent production work rather than structured learning.
If academic credit applies, include language making clear that the employer makes no representation the program meets university requirements and that credit approval is the student’s responsibility. Don’t overstate the legal significance of credit in your offer letter—and don’t imply that university approval makes the arrangement defensible. It doesn’t.
State clearly that completing the internship creates no entitlement to a job offer or preferential consideration for employment. This addresses Factor 7. But if your firm has a demonstrated pattern of converting summer interns to full-time offers, a blanket disclaimer won’t carry much weight in a later investigation. Use this language honestly, not as a shield for something that functions as a working audition.
For Houston energy employers specifically, confidentiality and IP assignment provisions aren’t optional boilerplate—they’re material risk management. Interns who access proprietary geological data, reservoir models, or field operations intelligence need agreements with scope that actually covers those categories. Standard NDA templates often don’t. Counsel review is advisable. IP assignment provisions should make clear that any work product created during the internship belongs to the employer.
For paid positions, state explicitly that the intern will be treated as a W-2 employee, that federal income tax and FICA will be withheld, and that a W-2 will be issued. Interns should know before they start whether they’ll receive a W-2 or a 1099. The answer should always be W-2 if they’re being paid for work. Include an at-will statement.
Both parties sign. Both parties keep a copy. The date matters. A verbal agreement followed by an offer letter the intern never signed is a weak compliance position—and in a wage-and-hour investigation, weak compliance positions tend to become expensive ones.
Sector-Specific Risks Worth Flagging With Counsel
Three categories of Houston employer face legal questions that go beyond the general FLSA framework.
Healthcare employers receiving Medicare or Medicaid funding need to evaluate unpaid intern arrangements against federal healthcare program participation requirements, not just FLSA. The intersection of intern classification and healthcare regulatory compliance is fact-specific enough that TMC-area employers shouldn’t rely on general DOL guidance. A hospital that runs afoul of FLSA intern classification may also face program integrity issues under Medicare rules—a considerably more serious problem than a back-pay order.
Energy sector employers whose interns will access proprietary geological, seismic, or operational data need internship agreements drafted with IP and trade secret law in mind. A standard commercial NDA may not adequately cover geoscience data, reservoir models, or operational intelligence with genuine competitive value. Firms running active exploration programs should have employment counsel—not just HR—review intern agreements. Inadequate confidentiality protections during an internship can create long-term business exposure that dwarfs any wage-and-hour liability.
Small plaintiff’s shops and litigation boutiques running unpaid arrangements for pre-law undergraduates or law students doing substantive legal work carry the highest-risk profile of any sector here. The combination is bad: an educated claimant who knows exactly how to file a wage claim, an accessible enforcement mechanism, market pressure from the Milbank scale, and a small legal community where word about a wage dispute travels fast. The reputational exposure compounds the financial risk in ways that outlast the underlying dispute. These arrangements are genuinely difficult to defend, and I’d push any small firm running one to reconsider before summer starts.
None of this is a substitute for legal advice specific to your situation. It identifies where to invest the time.
Houston Resources for Employers With Questions
The DOL Wage and Hour Division operates a Houston District Office covering the Gulf Coast region and accepts employer inquiry calls. For current contact information, use the DOL’s online office directory at dol.gov—confirm the location before filing or visiting, since district office addresses can shift with federal consolidations. The DOL also issues opinion letters for employers with specific compliance questions, though the process is slow and the letters are tightly fact-specific.
The Texas Workforce Commission handles unemployment insurance registration, reporting, and wage claim procedures. TWC’s employer hotline can direct you to the appropriate division for wage and hour complaints filed at the state level. Current hours and phone numbers are at twc.texas.gov.
For employment law counsel, the Houston Bar Association Lawyer Referral Service is a starting point. For intern classification specifically, look for attorneys with FLSA wage-and-hour experience. Ogletree Deakins and Jackson Lewis both have significant Houston presence and experience with energy sector compliance. Knowing what plaintiff-side wage-and-hour boutiques in Houston are filing is also genuinely useful context for understanding the claims environment.
The University of Houston Career Services office and Rice University’s Center for Career Development both publish internship benchmarking data and can provide context on what students in specific disciplines are being offered by competing employers. For rate-setting purposes, what UH and Texas A&M career offices are reporting from their employer partners is often more actionable than a national average—those schools are the most Houston-market-specific source available. The National Association of Colleges and Employers publishes annual intern pay survey data by region and field of study; NACE’s most recent engineering and business figures are worth checking as a cross-reference.
Verification note: federal minimum wage status should be confirmed before 2026 summer programs begin. The Milbank scale announcement typically comes in late fall or early winter. DOL Fact Sheet #71 revision status should be checked at dol.gov. Confirm with payroll counsel whether any IRS guidance has altered the treatment of intern stipends or housing allowances for the 2026 tax year. The framework here reflects federal standards as of early 2025. None of it is legal advice.
