When a job posting says “W2 only,” the employer is telling you upfront that the role will be filled as a payroll employee, not as an independent contractor or a corp-to-corp vendor. So what does W2 only mean in practice? You go on the company’s payroll, they withhold federal income tax, Social Security, and Medicare from every check, and after the calendar year closes you receive a Form W-2 summarizing your wages and the taxes already paid on your behalf. Alternative arrangements like 1099 contracting or billing through your own LLC are off the table for that job.
What the “Only” Rules Out
The word “only” is doing the work in that phrase. It tells you the employer will not accept a 1099 independent contractor setup, and it will not accept a corp-to-corp (C2C) arrangement where you invoice through your own corporation or LLC.
Those two alternatives look similar on the surface but sit in very different legal boxes than W2 employment. An independent contractor controls how the work gets done, pays their own self-employment taxes, and receives a Form 1099-NEC rather than a W-2. The hiring company doesn’t withhold taxes, doesn’t provide benefits, and doesn’t owe the contractor the protections of federal wage and hour law.
A C2C arrangement pushes further in the same direction. You form a corporation or LLC, and your entity contracts with the hiring company’s entity. You handle your own taxes, insurance, and retirement savings. C2C workers sometimes negotiate a higher hourly rate to offset the cost of self-funded benefits, but they carry the full overhead of running a business.
When a recruiter writes “W2 only,” they’ve already decided that neither of those structures fits the role. Trying to talk them into a 1099 or C2C for that specific posting is generally a dead end.
What Changes on Your Paycheck
As a W2 employee, you never see certain portions of your gross pay. Your employer withholds federal income tax from every check based on what you put on your Form W-4, and the amount depends on your filing status, dependents, and any extra withholding you request.
You also pay your share of FICA: 6.2% for Social Security on wages up to $184,500 in 2026, and 1.45% for Medicare on all wages with no cap. If your wages cross $200,000 in a calendar year, your employer withholds an additional 0.9% Medicare tax on the amount above that threshold, and that surtax comes out of your check only, with no matching employer share.
All of this shows up on the Form W-2 your employer issues after year-end. For the 2026 tax year, that W-2 has to be in your hands by February 1, 2027.
The Paperwork on Day One
Two federal forms are non-negotiable when you start a W2 job.
Form W-4 tells your employer how much federal income tax to hold back from each paycheck. Getting it right matters. Under-withhold and you’ll owe at tax time; over-withhold and you’ve given the government an interest-free loan for the year.
Form I-9 verifies your identity and legal authorization to work in the United States. You complete your section no later than your first day, and the employer must examine your original documents and finish their portion within three business days of your start date.
Most employers add state tax withholding forms, direct deposit setup, and benefits enrollment on top of those two, but W-4 and I-9 are the ones federal law requires for every hire.
Benefits and Protections That Come With the Classification
The practical upside of “W2 only” is everything a 1099 contractor or C2C worker doesn’t get. Some of it is required by law, some is at the employer’s discretion, but none of it extends to non-employees.
Employers with 50 or more full-time equivalent employees have to offer health insurance meeting minimum standards under the Affordable Care Act or face penalties. Smaller employers aren’t required to, and many still do.
The Fair Labor Standards Act gives non-exempt W2 employees the right to overtime pay of time-and-a-half for hours worked beyond 40 in a week. Whether you qualify depends on your salary and duties, but the protection exists only for employees, not contractors.
W2 employees at larger employers may also qualify for up to 12 weeks of unpaid, job-protected leave under the Family and Medical Leave Act once they meet the tenure and hours requirements. Nearly every state requires employers to carry workers’ compensation insurance for W2 employees injured on the job. The federal minimum wage of $7.25 per hour sets a floor, though many states and cities set higher ones.
Most W2 jobs in the United States are at-will, meaning either side can end the relationship at almost any time for almost any reason. Even so, W2 employees keep federal protection against being fired based on race, sex, religion, disability, age, and other protected characteristics. Those protections don’t apply the same way to independent contractors.
Why Employers Care About the Classification
Employers don’t specify “W2 only” arbitrarily. The IRS uses common-law rules to decide whether a worker is an employee or a contractor, and getting it wrong is expensive. The analysis looks at three areas: behavioral control, financial control, and the nature of the relationship.
Behavioral control is usually the biggest factor. If the company sets your hours, tells you how to do the work rather than just what result to deliver, provides your equipment, and supervises your methods, the IRS treats you as an employee, remote work included.
Financial control looks at whether the company reimburses your business expenses, pays a regular wage rather than a project fee, and whether you have any real chance to make a profit or take a loss based on your own business decisions.
The third area asks whether the company gives you benefits, whether the relationship is open-ended, and whether the work is central to the company’s business. A written contract calling you a “contractor” doesn’t override those facts. When a company decides the role fails the contractor tests, it posts the job as W2 only from the start.
If You Think You Should Be W2 but Aren’t
Misclassification, meaning being treated as a 1099 contractor when the law would call you an employee, is a common problem and costs the worker real money: lost benefits, no overtime protection, and the full self-employment tax burden instead of just the employee half.
If you believe your working relationship has been misclassified, you can file Form SS-8 with the IRS and ask for a formal determination of your status. The IRS reviews the facts and issues a ruling. State labor agencies can also pursue employers for unpaid unemployment insurance, workers’ compensation, and wage-and-hour violations, and a successful misclassification claim can recover back benefits, unpaid overtime, and reimbursement of self-employment taxes the employer should have been paying.
