Employer
A person, company, or organization that hires individuals to perform work in exchange for compensation. Employer status triggers specific legal obligations around taxes, workplace safety, anti-discrimination, and employee benefits.
What Is an Employer?
Key Takeaways
- ✓An employer is any person, business, or organization that hires and compensates individuals to perform work. This includes corporations, small businesses, nonprofits, government agencies, and individual households.
- ✓Employer status is defined by law, not by choice. Once you hire someone as an employee (versus a contractor), you become an employer with specific tax, safety, and compliance obligations.
- ✓The US has approximately 6.1 million employer firms, but 99.9% of them are small businesses with fewer than 500 employees (SBA, 2024). The employer experience varies dramatically by size.
- ✓Employers bear significant costs beyond salary: payroll taxes (7.65% for FICA alone), workers' compensation insurance, unemployment insurance, benefits, and administrative overhead typically add 30-40% to base compensation.
- ✓Many employment laws apply differently based on employer size. The threshold matters: 1 employee (IRCA), 15 (Title VII, ADA), 20 (ADEA, COBRA), 50 (FMLA, ACA), 100 (WARN Act).
An employer is a person or organization that hires individuals to perform work under its direction and compensates them for that work. Becoming an employer is a legal threshold that triggers a cascade of obligations around taxes, workplace safety, anti-discrimination, recordkeeping, and benefits. You don't choose to become an employer. You become one the moment you hire your first employee. That sounds obvious, but many small business owners and startup founders are surprised by what employer status actually requires. Hiring someone isn't just agreeing to pay them. It means registering for a federal Employer Identification Number (EIN), setting up payroll tax withholding, purchasing workers' compensation insurance, complying with OSHA safety standards, posting required workplace notices, and following anti-discrimination laws. According to the SBA, the total cost of employing someone is typically 1.25 to 1.4 times their base salary. An employee earning $80,000 actually costs the employer $100,000 to $112,000 when you factor in the employer's share of FICA (6.2% Social Security + 1.45% Medicare), federal and state unemployment taxes, workers' comp premiums, health insurance contributions, retirement plan matching, and administrative costs. For companies offering generous benefits, the multiplier can reach 1.5x or higher. The Kaiser Family Foundation's 2024 survey found that the average employer contribution for family health coverage alone was $17,034 per year.
What Are an Employer's Legal Obligations?
Employer obligations vary by jurisdiction and company size. Here are the major categories that apply to most US employers.
| Obligation Category | Key Requirements | Applies To (US) |
|---|---|---|
| Payroll Taxes | Withhold and remit federal/state income tax, FICA; pay employer FICA match, FUTA, SUTA | All employers with employees |
| Immigration Compliance | Complete Form I-9 for every employee; verify work authorization | All employers (IRCA, 1+ employees) |
| Anti-Discrimination | No discrimination in hiring, pay, promotion, termination based on protected characteristics | 15+ employees (Title VII, ADA); 20+ (ADEA) |
| Workplace Safety | Maintain safe working conditions; report injuries; OSHA compliance | All employers (general duty clause) |
| Wage and Hour | Pay minimum wage, overtime for non-exempt workers; maintain time records | All employers (FLSA) |
| Health Insurance | Offer affordable coverage to full-time employees or pay penalty | 50+ FTE employees (ACA) |
| Family/Medical Leave | Provide up to 12 weeks unpaid, job-protected leave | 50+ employees within 75 miles (FMLA) |
| COBRA | Offer continuation of group health coverage after qualifying events | 20+ employees |
| WARN Act | 60-day notice before mass layoffs or plant closings | 100+ employees |
| Recordkeeping | Maintain employee records (I-9, payroll, EEO-1) for specified retention periods | All employers; additional requirements by size |
How Does Employer Size Affect Obligations?
Employment law in the US uses employee count thresholds to determine which laws apply. This creates a staircase of increasing obligations as companies grow.
1 to 14 employees
Even the smallest employers must comply with FLSA (minimum wage, overtime), IRCA (I-9 verification), OSHA (general duty clause), EPPA (polygraph restrictions), and payroll tax requirements. State laws may add additional requirements: many states apply anti-discrimination protections at lower thresholds than federal law. California's FEHA applies at 5 employees. New York City's Human Rights Law applies at 4. This is where many small employers get into trouble: they assume employment law doesn't apply to them because they're small, but foundational requirements kick in with the very first hire.
15 to 49 employees
At 15 employees, Title VII and the ADA kick in, adding anti-discrimination, anti-harassment, and reasonable accommodation requirements. At 20, ADEA (age discrimination) and COBRA (health insurance continuation) apply. Companies in this range typically need their first dedicated HR person or a strong relationship with an employment attorney. The compliance complexity jumps significantly, and the consequences of non-compliance become more serious: EEOC complaints, DOL investigations, and private lawsuits become real risks.
50+ employees
This is the biggest compliance threshold. FMLA (family and medical leave) and the ACA's employer mandate (offer affordable health coverage or pay penalties) both kick in at 50 employees. EEO-1 reporting becomes mandatory. Many companies deliberately slow hiring as they approach 50 to prepare their compliance infrastructure. Others inadvertently cross the threshold without realizing the obligations it triggers, which is especially common for companies with distributed or seasonal workforces where the headcount fluctuates around the boundary.
What Does It Actually Cost to Be an Employer?
The true cost of employing someone extends far beyond their salary. Understanding these costs is essential for budgeting, pricing, and making build-vs-buy decisions.
| Cost Category | Approximate Cost (US) | Notes |
|---|---|---|
| Social Security (employer share) | 6.2% of wages up to $168,600 | Wage base adjusts annually |
| Medicare (employer share) | 1.45% of all wages (no cap) | Additional 0.9% on wages above $200K is employee-only |
| Federal Unemployment Tax (FUTA) | 6.0% on first $7,000 (effectively 0.6% after state credit) | Per employee, per year |
| State Unemployment Tax (SUTA) | 0.5% to 7%+ depending on state and experience rating | Varies dramatically by state and employer history |
| Workers' Compensation Insurance | $0.25 to $33.50 per $100 of payroll | Varies by industry risk and state |
| Health Insurance (employer share) | $7,034 single / $17,034 family per year | KFF 2024 averages; varies by plan design |
| Retirement Plan Matching | 3-6% of salary (if offered) | Most common: 50% match up to 6% of salary |
| Paid Time Off | 7-10% of salary equivalent | Based on average 15-20 PTO days per year |
| Administrative Overhead | 1-3% of payroll | HR, payroll processing, compliance, recordkeeping |
Types of Employers
Employer classification affects everything from tax treatment to employee rights and organizational governance.
Private sector employers
Private companies employ approximately 83% of US workers (BLS, 2024). They range from sole proprietorships with one employee to multinational corporations with hundreds of thousands. Private employers have the most flexibility in setting compensation, benefits, and workplace policies, constrained primarily by employment law minimums. They're also the most exposed to market pressures that drive layoffs, restructuring, and compensation adjustments.
Government employers
Federal, state, and local governments collectively employ about 22 million Americans (BLS, 2024). Government employment comes with distinct features: civil service protections that make termination difficult, defined benefit pension plans (increasingly rare in the private sector), and strong union representation. Government employers are exempt from some employment laws that apply to private employers. For example, federal employees can't sue under Title VII's punitive damages provisions, and some state employees have sovereign immunity protections.
Joint employers and co-employment
When two entities both exercise significant control over an employee's working conditions, both can be considered the employer. This happens most commonly with staffing agencies (the agency and the client company share employer responsibilities), franchise operations (the franchisor and franchisee may share liability under recent NLRB guidance), and professional employer organizations (PEOs). Joint employer status matters because it determines who is liable for wage violations, discrimination claims, and NLRA obligations. The definition has changed multiple times under different presidential administrations, creating ongoing uncertainty.
Why Does Employer Reputation Matter?
In competitive labor markets, being an employer isn't enough. You need to be an employer people want to work for. Employer branding has become a strategic priority because candidates have access to more information about potential employers than ever before.
The Glassdoor effect
Before Glassdoor (founded 2007), employer reputation traveled through personal networks. Now, any candidate can read reviews from current and former employees, see salary data, and view interview experiences. According to Glassdoor's 2024 research, 86% of job seekers read company reviews and ratings before applying. A one-star improvement on Glassdoor correlates with a 5% decrease in time-to-fill and a measurable increase in application quality. Companies can't control what employees write, but they can respond to reviews and, more importantly, address the underlying issues that generate negative feedback.
The cost of being a bad employer
A poor employer reputation has measurable financial consequences. Harvard Business School research found that companies with negative employer reputations pay a 10% wage premium to attract talent. They also experience higher turnover, which compounds costs. Meanwhile, companies consistently rated as great places to work (Fortune 100 Best, Glassdoor Best Places) receive 2-3x more applications per opening, allowing them to be more selective and build stronger teams. The math is straightforward: investing in being a good employer is cheaper than paying the premium for being a bad one.
