If you are a genuine employee, your employer is legally required to withhold federal income tax, Social Security tax, and Medicare tax from your paycheck and to pay its own matching share. So in most cases the answer is no, an employer cannot simply decide not to withhold taxes from an employee's wages. When taxes are missing from your check, the most common reason is that the company is treating you as an independent contractor (a 1099 worker) rather than an employee, sometimes correctly, but often as an illegal shortcut that shifts costs and risk onto you.
This question matters because missing withholding is frequently the first visible clue of a deeper problem: worker misclassification. Understanding the difference protects your future tax refund, your Social Security retirement and disability credits, and your eligibility for overtime, unemployment, and workers' compensation.
The Federal Baseline: Who Has to Withhold
Federal tax withholding is governed by the Internal Revenue Code and enforced by the Internal Revenue Service (IRS). Under the Federal Insurance Contributions Act (FICA), employers must withhold Social Security and Medicare taxes from employee wages and pay an equal employer share. Employers must also withhold federal income tax based on the information you provide, and they pay federal and state unemployment taxes on your behalf.
The key legal trigger is your status. These rules apply to employees. They do not apply to true independent contractors, who are responsible for paying their own taxes directly to the IRS. So whether your employer is allowed to skip withholding depends entirely on which category you actually fall into, and that is determined by the facts of how you work, not by what a contract or your boss calls you.
Employee vs. Independent Contractor: The Real Test
You do not get to choose your status, and neither does your employer just by labeling you. The IRS looks at the overall relationship, grouped into three areas:
- Behavioral control: Does the company direct how, when, and where you do the work? Do they train you and set your hours and methods? That points toward employee status.
- Financial control: Who provides tools and equipment? Are you reimbursed for expenses? Can you realize a profit or loss, and do you offer your services to the broader market? Contractors typically have their own business and bear financial risk.
- Relationship of the parties: Is the work ongoing and central to the company's core business? Do you receive benefits? A permanent, integral role suggests employment.
The U.S. Department of Labor's Wage and Hour Division uses a related but separate "economic reality" test under the Fair Labor Standards Act (FLSA) to decide whether you are economically dependent on the employer (an employee) or genuinely in business for yourself. Many states apply their own, often stricter, standards, including the "ABC test," which presumes you are an employee unless the company can prove all three of its conditions. Because these tests vary by state, the same job can be classified differently depending on where you work.
Signs You May Be Misclassified as a 1099 Contractor
Missing withholding plus several of these red flags is worth a closer look:
- You were given a Form 1099-NEC instead of a Form W-2, but you work like a regular employee.
- You were never asked to complete a Form W-4 (the form that tells an employer how much income tax to withhold).
- The company sets your schedule, supervises your work closely, and provides the tools and workspace.
- You work only for this one company, on an ongoing basis, doing work that is core to its business.
- You cannot hire helpers, subcontract, or take other clients.
- You were an employee, then "converted" to 1099 doing the exact same job.
Misclassification is not a harmless paperwork choice. It can cost you the employer's half of FICA, overtime pay you were owed under the FLSA, unemployment benefits, workers' compensation coverage, and protections under laws like Title VII, the ADA, and the FMLA that apply to employees but not contractors.
Can an Employer Not Withhold Federal Income Tax?
For a true employee, no. Federal income tax withholding is mandatory once wages and your W-4 information cross the relevant thresholds. An employer cannot lawfully agree to "pay you under the table" or hand you your full gross pay with no withholding if you are an employee. Doing so exposes both of you to back taxes, interest, and penalties. If your employer fails to withhold and remit, the IRS can still come after the unpaid amounts, and you may face a surprise tax bill plus possible underpayment penalties at filing time.
Can an Employer Not Withhold Social Security and Medicare (FICA) Tax?
For employees, FICA withholding is not optional, and you cannot waive it. Social Security and Medicare taxes fund your future retirement, disability, and survivor benefits, and your earnings record depends on these being reported correctly. When an employer skips FICA by treating you as a contractor, you end up owing self-employment tax (which covers both the employee and employer share) on your own. Over time, gaps in your reported earnings can reduce your Social Security benefits. A narrow exception exists for certain religious groups and a few specific categories of workers, but these are rare and require formal IRS approval, not a casual agreement.
