Most interns are treated as employees and get a W-2 because the business directs the work, sets expectations, and provides tools.
Internships are short and learning-heavy, so it’s easy to assume the paperwork is flexible. It isn’t. The way an intern is classified changes tax withholding, Social Security and Medicare taxes, and what form shows up after the year ends.
This article explains how W-2 and 1099 pay differ, why most internships fit W-2 payroll, and what to watch for during onboarding so you don’t get a tax surprise later.
What W-2 And 1099 Mean In Plain Terms
W-2 generally means “employee.” The company runs payroll, withholds taxes based on your forms, and pays the employer share of Social Security and Medicare taxes.
1099-NEC generally means “independent contractor.” You’re paid the full amount with no withholding by default, then you handle income tax and self-employment tax on your own tax return.
The label on an offer letter does not decide your status. The day-to-day relationship does: who controls the work, who takes financial risk, and whether you’re operating your own business or working inside theirs.
Intern Tax Status In Paid Internships: W-2 Is Common
Most internships look and feel like regular jobs with training built in. The company assigns tasks, sets deadlines, requires meetings, reviews work, and provides access to systems and tools. That pattern lines up with employee treatment under IRS common-law rules that focus on control and independence. The IRS overview in Topic No. 762 on worker classification explains the basic approach.
Also, internships often sit right inside the business workflow. You’re not selling a separate service to multiple clients. You’re working under a manager on the team’s priorities. That integration typically points to W-2 payroll.
Are Interns 1099 Or W-2? What Most Companies Should Use
For most paid internships, W-2 payroll is the right fit. A 1099 setup can make sense only when the intern is genuinely operating as an independent business: control over how the work is done, control over scheduling, the ability to serve other clients, and real financial risk.
If the internship looks like a staff role with training, meetings, and a manager directing the work, a 1099 label is often a mismatch.
How The IRS Evaluates Employee Vs Contractor Status
The IRS groups classification facts into three buckets: behavioral control, financial control, and the relationship of the parties. IRS Publication 1779 lays out these buckets in plain language.
Behavioral Control
This is about who has the right to direct the work. Are you trained on the process? Do you have to follow internal procedures? Are your hours set? Do you need approvals for how tasks are done? When a business can direct both what you do and how you do it, employee status is strongly suggested.
Financial Control
This is about financial independence. Contractors often invest in their own equipment, can make a profit or take a loss, set prices, and manage expenses. Many interns are paid an hourly wage or a set payroll stipend and don’t take on business-like risk.
Type Of Relationship
This includes written agreements, whether the work is ongoing or short term, whether benefits exist, and whether the work is a core part of the business. A short internship can still be employee work. Duration alone does not decide status.
Fast Signs You Can Check During Onboarding
You can often tell what the company plans by the onboarding packet and how pay is set up.
- You’re asked for a W-4 and an I-9, and you’ll be added to a payroll system.
- You’re told when to work, when meetings happen, and who approves your work.
- You’re given company accounts, a company laptop, or required internal tools.
- You’re paid on a regular schedule like weekly or biweekly payroll.
Those signs point to W-2 employee treatment. If you’re asked for a W-9, told to invoice, and given broad freedom over timing and method, that can point toward contractor treatment. Still, a W-9 request does not make the classification correct by itself.
Common Internship Setups And Where They Tend To Land
Internships come in a few common shapes. The pay mechanics can differ, yet the classification often stays the same because the work relationship stays the same.
Hourly Paid Internships
Hourly pay paired with timekeeping is standard employee structure. It usually goes through payroll with withholding and a W-2 at year end.
Stipend Internships
A stipend can still be wages. Many employers pay a set amount per pay period through payroll and issue a W-2. Ask whether withholding will happen and how often you’ll be paid. You want that answer in writing.
School Credit Plus Pay
School credit does not change tax treatment on its own. If you’re paid and the business controls the work, wages reported on a W-2 are common.
Unpaid Internships
Unpaid roles raise wage-and-hour issues, which is separate from tax forms. If there is no pay, there may be no W-2 or 1099 because there’s no income to report. For private, for-profit employers, the U.S. Department of Labor uses a “primary beneficiary” test to evaluate unpaid internships. See DOL Fact Sheet #71 for the criteria used in that wage-and-hour review.
Next, here’s a scan-friendly map that compares common signals side by side.
Table #1 (broad/in-depth, 7+ rows, <=3 columns)
| What You Can Observe | Leans W-2 Employee | Leans 1099 Contractor |
|---|---|---|
| Schedule | Set hours, required availability, time tracking | Chooses hours; only deadline matters |
| Work direction | Manager assigns tasks and process steps | Worker chooses method and workflow |
| Training | Onboarding training and ongoing coaching | Little training; expected to arrive ready |
| Tools and access | Company laptop, accounts, internal systems | Own equipment and software; limited internal access |
| Pay style | Payroll wage or payroll stipend on set pay dates | Invoices per project or milestone |
| Ability to serve others | Restricted side work or approval required | Free to work for other clients |
| Financial risk | No real business expenses; no chance of loss | Can spend money to perform work; can lose money |
| Integration with the team | Work is part of the team’s ongoing output | Separate service with a clear deliverable boundary |
| Scope changes | Tasks can shift week to week | Scope changes tend to require a new agreement |
Paperwork You’ll See In A W-2 Internship
Employee onboarding is built around identity verification and tax withholding.
- Form I-9 to verify work authorization.
- Form W-4 so the employer can calculate federal withholding.
- State withholding forms, depending on the state.
- Direct deposit setup and payroll profile.
At year end, you receive a W-2 reporting wages and withholding. Save it. You’ll use it to file your return.
Paperwork You’ll See In A 1099 Setup
Contractor onboarding is simpler on the payer side and heavier on the worker side.
- Form W-9 so the payer can collect your name and taxpayer ID.
- Invoices you send for your work, based on the agreement.
- At year end, many payers send Form 1099-NEC if payments total $600 or more.
Contractor pay often comes with a tax reality check: self-employment tax. Employees split Social Security and Medicare taxes with the employer. Contractors generally pay both halves through self-employment tax on their return.
What Misclassification Can Do To Both Sides
For interns, misclassification can mean no withholding and a larger tax bill at filing time. It can also mean confusion around benefits, overtime rules, and on-the-job protections that often tie to employee status.
For employers, misclassification can lead to back payroll taxes, penalties, and messy corrections. It can also trigger investigations across agencies, not just tax review, since pay practices tend to connect across systems.
When Things Feel Mixed: Getting A Real Determination
Some roles sit near the line: a remote intern who works project-by-project with minimal meetings, or a short creative engagement that looks more like a service than a staff role. When the facts are mixed, get the classification decision in writing and keep a clear record of how the relationship actually operates.
If a worker wants an IRS determination, the IRS provides a process using Form SS-8. The IRS may ask questions from both the worker and the business, and the process can take time. Still, it’s a direct route when classification feels off.

Second Table: Quick Checklist For The Form You Should Expect
Use this as a quick onboarding checklist. It connects what you’re being asked to do with the form flow that tends to match.
| Onboarding Signal | Form Flow That Fits | Practical Next Step |
|---|---|---|
| You complete W-4 and I-9 | Payroll withholding, then W-2 in January | Check pay stubs for withholding and keep copies |
| You’re asked for a W-9 | Paid gross, then 1099-NEC if $600+ | Set aside money for taxes and track expenses |
| You must follow a set daily schedule | W-2 often fits better | Ask why you aren’t on payroll if you’re treated like staff |
| You use company systems and equipment | Often points to W-2 | Write down what tools are provided and who directs work |
| You control method and timing | Can fit 1099 when other facts match | Get scope, deadline, and ownership terms in writing |
| The role is unpaid | No tax form when there is no pay | Read the DOL internship criteria before starting |
How Interns File Taxes Based On The Form They Receive
If you receive a W-2, filing is typically straightforward. You report wages from the form and claim the withholding shown. If you had more than one job, your return includes all W-2s.
If you receive a 1099-NEC, you report the income as self-employment income and can deduct ordinary business expenses tied to that work. Keep receipts and a simple log of purchases. Many contractors also make estimated tax payments during the year to avoid a big bill at filing time.
If your form looks wrong, act early. Ask the payer for a corrected form. Corrected W-2s and corrected 1099s happen, and the fix is easier when it’s handled promptly.
Red Flags That Suggest A 1099 Label Is Being Used The Wrong Way
- You’re told “1099 is simpler,” yet you have set hours, set tasks, and close supervision.
- You do the same kind of work as employees on the team, under the same manager.
- You’re restricted from doing other paid work during the internship.
- You’re paid like an employee (regular wage schedule) while still being told to invoice.
No single bullet decides status, still these patterns are worth pausing on. If the relationship looks like a job in practice, W-2 payroll is often the clean match.
Final Notes For A Clean Internship
Most interns belong on W-2 payroll: withholding is clearer, the tax form is predictable, and the employer handles the employer-side payroll taxes. A 1099 arrangement can fit only when the intern is truly operating as an independent business with control over the work and real independence from the payer.
If you want one simple action item, it’s this: match the form flow to the reality of the relationship. When those two align, your taxes get boring in the best way.
