When a job posting says “W2 only,” the employer is telling you it will hire you as a regular payroll employee and nothing else. You cannot take the role as a 1099 independent contractor, and you cannot invoice through your own LLC or S-corp on a corp-to-corp basis. Your pay will run through the company’s payroll (or a staffing agency’s), income and payroll taxes will be withheld from every check, and you will get a Form W-2 in January covering the prior year’s wages and withholdings.
That single line in the ad settles a lot of downstream questions about your taxes, your paycheck, and the protections you’ll have on the job. Here is what it actually changes for you.
Why Employers Specify W2 Only
Companies write “W2 only” to close off the contractor route before applications come in. Under federal law, a worker is generally presumed to be an employee unless the hiring company can show the relationship meets the legal test for independent contractor status. The IRS looks at how much control the company has over the work, who supplies the tools, whether the role is ongoing, and whether the worker receives benefits. A contract calling someone a “contractor” does not settle the question if the day-to-day reality looks like employment.1Internal Revenue Service. Publication 15 (2026), (Circular E), Employer’s Tax Guide
Getting that call wrong is expensive for the employer. A company that misclassifies an employee as a contractor can be held liable for the income tax it should have withheld and for both halves of Social Security and Medicare taxes, with a trust fund recovery penalty that can reach 100 percent of the unpaid tax.1Internal Revenue Service. Publication 15 (2026), (Circular E), Employer’s Tax Guide Requiring W2 status from the start removes that risk. It’s also often a client requirement passed down through vendors: many large companies will not let contractors on site through a staffing supplier unless those workers are on someone’s W2 payroll.
When the “Employer” Is a Staffing Agency
A large share of W2-only postings are actually filled through staffing firms. In that arrangement, the staffing agency is your legal employer. The agency runs payroll, withholds your taxes, issues your W-2, carries workers’ compensation coverage, and pays unemployment insurance on your behalf. The client company you report to each day directs your work but is not on your tax paperwork. If the posting comes from a recruiter or agency, expect this structure, and ask up front which entity will actually employ you and whether benefits like health insurance are offered through the agency.
What Your Paycheck Looks Like
As a W2 employee, taxes come out of every check automatically. You never write a quarterly estimated tax payment to the IRS on your wages, and you never have to set money aside for a self-employment tax bill in April.
Your employer withholds federal income tax based on what you tell it on Form W-4 when you’re hired, and you can update that form anytime your situation changes.2Internal Revenue Service. Form W-4 – Employee’s Withholding Certificate Your share of FICA also comes out of each check:
- Social Security: 6.2 percent of wages, up to the 2026 wage base of $184,500. Earnings above that are not subject to Social Security tax.3Social Security Administration. Contribution and Benefit Base
- Medicare: 1.45 percent of all wages, with no cap.4Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates
- Additional Medicare Tax: an extra 0.9 percent on wages above $200,000 for a single filer, withheld from the employee only.5Internal Revenue Service. Topic No. 560, Additional Medicare Tax
Your employer pays a matching 6.2 percent for Social Security and 1.45 percent for Medicare from its own funds. You never see that amount on your pay stub, but it is the key reason W2 workers cost the company more than contractors.4Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates
By January 31 of the following year, you’ll receive your Form W-2 summarizing wages and all taxes withheld. You use it to file your annual return.6Internal Revenue Service. About Form W-2, Wage and Tax Statement If it hasn’t arrived by the end of February, contact the IRS.7Internal Revenue Service. If You Don’t Get a W-2 or Your W-2 Is Wrong
How This Compares to 1099 Pay
The headline number a lot of people compare is the payroll-tax split. A W2 employee pays 7.65 percent of wages toward Social Security and Medicare while the employer covers a matching 7.65 percent. A 1099 contractor pays the full 15.3 percent as self-employment tax because there is no employer on the other side.4Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates Contractors get to deduct half of that self-employment tax when calculating adjusted gross income, but the out-of-pocket hit is still bigger. Contractors also have to make quarterly estimated tax payments on their own; missing them triggers penalties. That is the trade-off a “W2 only” posting closes off, in both directions: you give up the higher gross hourly rate a contractor might negotiate, and you give up the deductions and business structure a contractor can use, in exchange for withholding, an employer match, and the protections below.
Protections That Come With W2 Status
Federal employment law hangs on the employee/contractor line. Taking a W2 job puts you on the employee side of that line, which means the following protections attach to your work.
Minimum Wage and Overtime
The Fair Labor Standards Act requires employers to pay at least the federal minimum wage and to pay non-exempt employees one and a half times their regular rate for hours worked beyond 40 in a workweek.8U.S. Department of Labor. Wages and the Fair Labor Standards Act Many states set higher minimums that override the federal floor.
Not every W2 employee gets overtime, though. The FLSA carves out “exempt” workers, generally those paid on a salary basis at or above a set threshold who perform executive, administrative, or professional duties. The Department of Labor is currently enforcing a threshold of $684 per week, or $35,568 per year, after a federal court vacated a 2024 rule that would have raised it.9U.S. Department of Labor. Earnings Thresholds for the Executive, Administrative, and Professional Exemption If your salary is below that, you’re almost certainly entitled to overtime regardless of what your job title says.
Unemployment Insurance
Your employer pays into federal and state unemployment programs on your behalf. The federal unemployment tax is 6.0 percent on the first $7,000 of your wages, reduced to an effective 0.6 percent for employers that also pay state unemployment tax.10Internal Revenue Service. FUTA Credit Reduction Those contributions fund the benefits you can claim if you lose the job through no fault of your own.11Employment and Training Administration – U.S. Department of Labor. Unemployment Insurance Tax Topic Independent contractors are not covered.
Workers’ Compensation
Employers must carry workers’ compensation insurance, which pays medical costs and replaces part of your lost wages if you’re hurt on the job.12U.S. Department of Labor. Workers’ Compensation The specifics are set state by state.
Family and Medical Leave
The Family and Medical Leave Act gives eligible employees up to 12 weeks of unpaid, job-protected leave a year for reasons including a serious health condition or the birth of a child. You qualify if your employer has at least 50 employees within 75 miles of your worksite, you’ve been there at least 12 months, and you’ve logged at least 1,250 hours in the 12 months before your leave.13U.S. Department of Labor. Fact Sheet #28: The Family and Medical Leave Act
Employer Health Coverage
If your employer averaged at least 50 full-time employees (including full-time equivalents) in the prior year, the ACA requires it to offer minimum essential health coverage to at least 95 percent of its full-time employees.14Internal Revenue Service. Employer Shared Responsibility Provisions Full-time for this purpose means averaging at least 30 hours a week or 130 hours a month.15Internal Revenue Service. Identifying Full-Time Employees Smaller employers are not required to offer coverage, though many do. Contractors are excluded from the mandate.
Paperwork on Your First Day
Two federal forms are non-negotiable when you start a W2 job:
- Form W-4 tells your employer how much federal income tax to withhold. You can update it anytime.2Internal Revenue Service. Form W-4 – Employee’s Withholding Certificate
- Form I-9 verifies your identity and work authorization. You must complete Section 1 by your first day, and your employer has three business days from your start date to review your documents and finish Section 2.16U.S. Citizenship and Immigration Services. Who Must Complete Form I-9
Most states add a separate withholding certificate and their own new-hire reporting. Your employer or staffing agency handles the filing.
If a Job You Already Have Looks Like W2 Work but Pays 1099
The flip side of a “W2 only” ad is a job that should have been W2 but wasn’t. If you follow a set schedule, use company equipment, and take direction on how to do the work, but you’re receiving a 1099, you may be misclassified. It costs you: you’re paying the full 15.3 percent self-employment tax instead of the 7.65 percent employee share, and you have no access to unemployment, overtime, or workers’ comp.
You can ask the IRS to decide your status by filing Form SS-8, Determination of Worker Status. Mail or fax it separately from your tax return.17Internal Revenue Service. Instructions for Form SS-8 While that plays out, you can file Form 8919 with your return to pay only the 7.65 percent employee share of Social Security and Medicare tax rather than the full self-employment tax, and to make sure your wages are credited to your Social Security record.18Internal Revenue Service.
