A W-2 worker is an employee — someone who performs services under a company’s legal control, has federal and state taxes withheld from every paycheck, and receives an IRS Form W-2 each January summarizing the year’s wages and withholdings. That classification is what separates you from an independent contractor: the employer handles payroll taxes, pays a matching share of Social Security and Medicare, and owes you the legal protections that come with employment, including overtime rules, unemployment coverage, and workers’ compensation.
How the IRS Decides You’re an Employee
The label on your offer letter doesn’t settle the question. The IRS uses common-law rules that turn on a single idea: can the company control what work gets done and how it gets done? If yes, you’re an employee, even if you have significant day-to-day freedom.1Internal Revenue Service. Employee (Common-Law Employee)
Three categories of evidence go into the call. Behavioral control looks at whether the company directs when, where, and how you work — set hours, required methods, mandatory training. Financial control looks at whether you use company equipment, take no capital risk, and can’t earn a profit or loss based on how efficiently you work. Type of relationship considers whether the job is open-ended and central to the company’s regular business, and whether there’s a written contract or benefit package. Substance beats labels; calling someone a contractor doesn’t make them one.
What Comes Out of Your Paycheck
Every W-2 paycheck has several taxes taken out before you see the money. Under the Federal Insurance Contributions Act, your employer withholds 6.2% for Social Security and 1.45% for Medicare, and pays a matching amount from its own funds.2Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates Social Security tax stops after the first $184,500 of wages in 2026;3Social Security Administration. Contribution and Benefit Base Medicare has no cap.
Once your wages cross $200,000 in a calendar year, the employer must also withhold an Additional Medicare Tax of 0.9%. The employer does not match that one. Whether you actually owe it depends on your filing status: married couples filing jointly owe it on combined wages above $250,000, and married individuals filing separately owe it above $125,000.4Internal Revenue Service. Questions and Answers for the Additional Medicare Tax Anything withheld that you don’t owe comes back at tax time.
Federal income tax withholding runs off the Form W-4 you give your employer. That form tells payroll your filing status and any adjustments for dependents, other income, or extra deductions.5Internal Revenue Service. About Form W-4, Employee’s Withholding Certificate Withhold too little and you’ll owe in April, possibly with an underpayment penalty. Most states, and some cities, add their own income tax withholding on top.
Bonuses and commissions are treated differently. When supplemental pay is issued separately, the employer can withhold a flat 22% for federal income tax instead of using your W-4. Supplemental wages above $1 million in a year are withheld at 37%.6Internal Revenue Service. Publication 15 (2026), (Circular E), Employer’s Tax Guide Those are withholding rates, not your final tax rate; the actual bill gets settled on your return.
What Your Employer Pays That You Never See
Several real costs of hiring you never appear on your pay stub because the employer covers them entirely. This is a large part of what makes W-2 status different from contracting.
The Federal Unemployment Tax Act charges employers 6.0% on the first $7,000 of each employee’s yearly wages, though employers who pay state unemployment tax on time get a credit of up to 5.4%, cutting the effective FUTA rate to 0.6%.7Internal Revenue Service. Topic No. 759, Form 940, Employers Annual Federal Unemployment (FUTA) Tax Return – Filing and Deposit Requirements State unemployment taxes fund the benefits paid to workers who lose their jobs through no fault of their own, and rates vary by state and by the employer’s history of layoffs.
Workers’ compensation insurance covers medical bills and lost wages if you’re hurt on the job. Nearly every state requires employers to carry it, and the premium is entirely the employer’s cost. Rates track industry risk and the company’s claims history.
Health coverage is a different rule. Employers with 50 or more full-time employees, counting full-time equivalents, are Applicable Large Employers and must offer affordable coverage to their full-time workers or face tax penalties.8Internal Revenue Service. Employer Shared Responsibility Provisions Smaller employers aren’t required to offer insurance, though many do.
Overtime and the Exempt vs. Non-Exempt Line
Not every W-2 employee earns overtime. The Fair Labor Standards Act splits workers into non-exempt employees, who must be paid at least time-and-a-half for hours over 40 in a workweek, and exempt employees, who don’t get overtime regardless of hours worked. The right to overtime can’t be waived by agreement, and a “no unauthorized overtime” policy doesn’t cancel the obligation to pay for hours you actually worked.9U.S. Department of Labor. Fact Sheet #23: Overtime Pay Requirements of the FLSA
To be exempt from overtime, an employee generally has to earn at least $684 per week ($35,568 annually) on a salary basis and perform duties that fit one of the white-collar exemptions. A higher threshold of $1,128 per week ($58,656 annually) was scheduled to take effect in 2025 under a 2024 rule, but a federal court vacated that rule, and the Department of Labor is enforcing the 2019 threshold.10U.S. Department of Labor. Earnings Thresholds for the Executive, Administrative, and Professional Exemption From Minimum Wage and Overtime Protections Under the FLSA
Salary alone isn’t enough. The job duties also have to fit one of these categories:
- Executive: your primary duty is managing a department or the business, you regularly direct at least two full-time employees, and you have meaningful input into hiring and firing.
- Administrative: you perform office or non-manual work directly related to business operations and regularly exercise independent judgment on significant matters.
- Professional: your work requires advanced knowledge in a field of science or learning, usually acquired through specialized education, or requires invention and originality in a creative field.
An employee well above the salary threshold who doesn’t exercise independent judgment or manage others is still entitled to overtime.11U.S. Department of Labor. Fact Sheet #17A: Exemption for Executive, Administrative, Professional, Computer and Outside Sales Employees Under the Fair Labor Standards Act (FLSA)
Job-Protected Leave
W-2 employees can qualify for up to 12 weeks of unpaid, job-protected leave per year under the Family and Medical Leave Act, but three conditions all have to be true: you’ve worked for the employer for at least 12 months, you’ve logged at least 1,250 hours in the 12 months before leave starts, and your employer has at least 50 employees within 75 miles of your worksite.12U.S. Department of Labor. Fact Sheet #28: The Family and Medical Leave Act Independent contractors get no FMLA rights, however long they’ve worked with a client. Some states run their own paid family leave programs with different rules on top of the federal floor.
Reading Your W-2 Form
Your employer has to get your W-2 to you by January 31 each year.13Internal Revenue Service. About Form W-2, Wage and Tax Statement You need it to file your federal and state returns.
Box 1 shows taxable wages, tips, and other compensation after pre-tax deductions like 401(k) contributions and health insurance premiums come out. Box 2 shows federal income tax withheld. Boxes 3 through 6 break out Social Security and Medicare wages and the tax withheld on each. Box 12 uses letter codes for items like 401(k) contributions (Code D), employer HSA contributions (Code W), and the total cost of employer-sponsored health coverage (Code DD).
If the form is wrong — Social Security number, wages, tax withheld — ask your employer for a corrected W-2. The employer files Form W-2c with the Social Security Administration and gives you a copy.14Internal Revenue Service. About Form W-2 C, Corrected Wage and Tax Statements Don’t file a return with numbers you know are wrong. If the employer won’t fix it, contact the IRS.
Employers that don’t issue W-2s on time face per-form penalties for 2026 returns: up to $60 per form for filings up to 30 days late, $130 per form from 31 days through August 1, $340 per form after August 1 or not filed at all, and $680 per form for intentional disregard.15Internal Revenue Service. Information Return Penalties
One narrow wrinkle to know about: a small group of workers — certain commission delivery drivers, full-time life insurance agents selling for one company, home workers producing goods to company specifications, and full-time traveling salespeople — are treated as “statutory employees.” Their W-2 has Box 13 checked, and they report income differently at tax time.16Internal Revenue Service. Statutory Employees If Box 13 isn’t checked, this doesn’t apply to you.
If You Think You’ve Been Misclassified
Some workers who should be W-2 employees are paid as 1099 contractors instead, which shifts the full 15.3% self-employment tax onto them and cuts them out of unemployment, workers’ comp, overtime, and FMLA. Misclassification is something the IRS and the Department of Labor actively pursue.
If you believe your classification is wrong, you can file Form SS-8 with the IRS to request an official determination of your worker status.17Internal Revenue Service. About Form SS-8, Determination of Worker Status for Purposes of Federal Employment Taxes and Income Tax Withholding These determinations take time, but a favorable one creates a paper trail that supports claims for back wages, unpaid benefits, and tax adjustments.
On the employer side, when the IRS reclassifies a worker, the company owes 1.5% of the worker’s wages for income tax withholding and 20% of the employee’s share of FICA that should have been withheld — figures that double to 3% and 40% if the required 1099s were never filed18Office of the Law Revision Counsel. 26 U.S. Code 3509 – Determination of Employer’s Liability for Certain Employment Taxes — on top of the full employer share of FICA, FUTA, and any unpaid state taxes. Employers that consistently treated workers as contractors, filed the right 1099s, and had a reasonable basis for the call (industry practice, a prior IRS audit, or judicial precedent) can claim Section 530 relief from the tax liability.19Internal Revenue Service. Worker Reclassification – Section 530 Relief
Hold onto your W-2s and pay stubs for at least four years. You may need them for tax disputes, loan applications, or benefit claims well after the filing deadline passes.
