The benefits full-time employees are entitled to under federal law are narrower than most people assume. Your employer must pay into Social Security, Medicare, and unemployment insurance on your behalf, carry workers’ compensation coverage (required in nearly every state), and, if the company has 50 or more full-time workers, offer affordable health insurance. Larger employers must also provide unpaid, job-protected family and medical leave to eligible workers. Paid vacation, retirement matching, dental coverage, and most other perks associated with a salaried job are entirely optional.
What Counts as Full-Time
There is no single federal definition. The Fair Labor Standards Act leaves it to each employer to set a full-time threshold for internal purposes, so one company might use 35 hours a week and another 40.1U.S. Department of Labor. Full-Time Employment
The Affordable Care Act uses a firmer rule. For health coverage obligations, a full-time employee is anyone averaging at least 30 hours per week or 130 hours per month.2Internal Revenue Service. Identifying Full-Time Employees That means you can be classified as part-time by your employer’s handbook but still count as full-time for insurance purposes.
Benefits Your Employer Must Provide
Social Security and Medicare
Every employer, regardless of size, contributes to Social Security and Medicare on your behalf. The employer pays 6.2 percent of your wages toward Social Security (on earnings up to $184,500 in 2026) and 1.45 percent toward Medicare, with no earnings cap on the Medicare portion.3Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates You pay matching amounts through payroll withholding.
Unemployment Insurance
Employers fund unemployment insurance through federal and state payroll taxes. Federal tax is collected under the Federal Unemployment Tax Act, and separate state taxes fund actual benefit payments to workers who lose their jobs through no fault of their own.4U.S. Department of Labor. Unemployment Insurance Tax Topic Employees do not pay into the system directly.
Workers’ Compensation
Nearly every state requires employers to carry workers’ compensation insurance, which pays medical costs and a portion of lost wages if you are injured on the job. It is a no-fault system, so you do not need to prove employer negligence to receive benefits. Coverage rules vary by state, and the requirement usually kicks in with a single employee.
Unpaid Family and Medical Leave
The Family and Medical Leave Act gives eligible workers up to 12 weeks of unpaid, job-protected leave per year for a serious personal health condition, to care for a spouse, child, or parent with a serious health condition, or for the birth or adoption of a child.5U.S. Department of Labor. Fact Sheet #28F: Reasons That Workers May Take Leave Under the Family and Medical Leave Act A separate provision allows up to 26 weeks of leave to care for a family member who is a current service member or recent veteran with a serious injury.6U.S. Department of Labor. Fact Sheet #28A: Employee Protections Under the Family and Medical Leave Act
To qualify, you must meet all three of these conditions:
- You have worked for the employer for at least 12 months.
- You have logged at least 1,250 hours in the 12 months before your leave begins.
- Your employer has at least 50 employees within 75 miles of your work location.
Your employer must keep your group health benefits going on the same terms during FMLA leave and must restore you to the same or an equivalent position when you return.6U.S. Department of Labor. Fact Sheet #28A: Employee Protections Under the Family and Medical Leave Act The leave itself is unpaid, though your employer may allow (or require) you to use accrued paid time off concurrently. If you work for a smaller company or fall short of the hours requirement, FMLA does not apply.
Health Insurance at Larger Employers
Under the ACA, companies with 50 or more full-time or full-time-equivalent employees must offer affordable health coverage to at least 95 percent of their full-time workforce.7Internal Revenue Service. Employer Shared Responsibility Provisions For this purpose, full-time means the 30-hour ACA standard, not the employer’s internal classification.2Internal Revenue Service. Identifying Full-Time Employees
Coverage must also be affordable. For 2026, your required contribution toward the lowest-cost self-only plan cannot exceed 9.96 percent of your household income.8Internal Revenue Service. Rev. Proc. 2025-25 If your share of the premium exceeds that threshold, the plan is not considered affordable and you may qualify for a premium tax credit through the marketplace instead.
If you work for a company with fewer than 50 full-time employees, federal law does not require your employer to offer health insurance at all. Some small employers offer it voluntarily, but there is no federal mandate.
Continuing Health Coverage After a Job Loss
If you lose your job or your hours drop enough to lose eligibility for your employer’s health plan, COBRA lets you continue that coverage temporarily. The law applies to employers with 20 or more employees.9U.S. Department of Labor. FAQs on COBRA Continuation Health Coverage for Employers and Advisers
How long you can stay on COBRA depends on why you lost coverage:
- 18 months for job loss (other than for gross misconduct) or a reduction in hours.
- 36 months for divorce or legal separation, death of the covered employee, a dependent child aging out of coverage, or the covered employee becoming eligible for Medicare.
You have at least 60 days after receiving the election notice to decide whether to enroll.10U.S. Department of Labor. FAQs on COBRA Continuation Health Coverage for Workers The premium is the full plan cost (the portion your employer used to pay plus your share) plus a 2 percent administrative fee, up to 102 percent of the total.9U.S. Department of Labor. FAQs on COBRA Continuation Health Coverage for Employers and Advisers Expect sticker shock, since most employees only see their own share of the premium while employed.
Benefits Your Employer Does Not Have to Provide
Many benefits people associate with a full-time job are voluntary under federal law. Paid vacation, holiday pay, bereavement leave, severance, and dental or vision insurance are all optional. Employers offer them to compete for workers, but no federal statute requires any of them. Roughly 18 states and Washington, D.C. mandate some amount of paid sick leave, typically one hour earned for every 30 to 40 hours worked.
Retirement plans work the same way. No law requires your employer to offer a 401(k) or to match your contributions. If your employer does offer one, you can contribute up to $24,500 in 2026, with additional catch-up amounts available at age 50 and older.11Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
Once an employer does establish a retirement or health plan, the Employee Retirement Income Security Act sets the ground rules. ERISA doesn’t force any employer to create a plan, but it requires those that do to meet minimum standards for transparency, funding, and fiduciary responsibility.12U.S. Department of Labor. FAQs About Retirement Plans and ERISA You are entitled to a Summary Plan Description explaining your benefits and rights within 90 days of enrolling.13Internal Revenue Service. 401(k) Resource Guide – Plan Participants – Summary Plan Description
Health Savings Accounts (paired with high-deductible health plans) and Flexible Spending Accounts are also optional. Neither is required by law; both depend on your employer making them available.
How Benefits Are Taxed
The real value of a benefit depends partly on how it is taxed. Several common ones are excluded from your taxable wages, in whole or in part:
- Employer-paid premiums for health, dental, and vision coverage are not treated as taxable wages.14Internal Revenue Service. Employee Benefits
- Employer-provided group life insurance is tax-free up to $50,000 in coverage; anything above that is taxable.15Internal Revenue Service. Group-Term Life Insurance
- Employer tuition or education assistance is tax-free up to $5,250 per year.16Internal Revenue Service. Employer’s Tax Guide to Fringe Benefits (Publication 15-B)
- Qualified transit passes and parking are excluded up to $340 per month in 2026.16Internal Revenue Service. Employer’s Tax Guide to Fringe Benefits (Publication 15-B)
- Dependent care assistance is excluded up to $7,500 per year ($3,750 if married filing separately).16Internal Revenue Service. Employer’s Tax Guide to Fringe Benefits (Publication 15-B)
The default rule is that any fringe benefit your employer provides is taxable income unless a specific provision excludes it.16Internal Revenue Service. Employer’s Tax Guide to Fringe Benefits (Publication 15-B) If you receive an unusual perk like a company car, stock options, or an achievement award, check your pay stub for extra withholding.
If Your Employer Is Not Providing Required Benefits
If your employer is violating FMLA, failing to pay into Social Security or Medicare, or refusing to offer required health coverage, you can file a complaint with the Department of Labor’s Wage and Hour Division online or by calling 1-866-487-9243.17Worker.gov. Filing a Complaint With the U.S. Department of Labor’s Wage and Hour Division The nearest field office will contact you within two business days. If an investigation finds a violation, you may recover lost wages or benefits.
For health coverage specifically, you can also flag the issue through the Health Insurance Marketplace when you apply for individual coverage. Receiving a premium tax credit through the marketplace can itself trigger a penalty assessment against an employer that should have offered affordable coverage but did not.
