Employment Law Basics Every Small Business Owner Must Know

Why Employment Law Matters for Small Businesses

Hiring employees is a major milestone for any small business. It is also the moment when a new set of legal obligations kicks in. Employment law violations can result in lawsuits, government audits, and penalties that can cripple a small business. The good news: understanding the basics is not as complicated as it seems.

This guide covers the essential employment laws that apply to small businesses, when each one kicks in, and practical steps you can take to stay compliant.

Before You Hire: Setting Up Properly

Employee vs. Independent Contractor

One of the most common (and costly) mistakes small businesses make is misclassifying workers. The IRS and Department of Labor use several factors to determine classification:

• Behavioral control: Do you control how the work is done, or just the result?
• Financial control: Does the worker invest in their own equipment? Can they earn a profit or suffer a loss?
• Relationship type: Is there a written contract? Are benefits provided?

Getting this wrong can result in back taxes, penalties, and lawsuits. When in doubt, consult with an employment attorney or use the IRS Form SS-8 to request a determination.

Required Paperwork for New Hires

When you bring on an employee, you need to complete several forms:

• Form I-9: Verifies employment eligibility. Must be completed within three days of the hire date
• Form W-4: Employee's withholding certificate for federal income tax
• State W-4 equivalent: Many states have their own withholding forms
• New hire reporting: Most states require you to report new employees within 20 days

Federal Employment Laws by Business Size

Not all federal employment laws apply to every business. Here is when each one kicks in:

1 or More Employees

• Fair Labor Standards Act (FLSA): Minimum wage ($7.25 federal; many states are higher), overtime rules, child labor protections, and recordkeeping
• Employee Polygraph Protection Act: Prohibits most private employers from using lie detector tests
• OSHA: Workplace safety standards apply to nearly all employers
• EPPA, USERRA, and IRCA: Various protections for employees

15 or More Employees

• Title VII of the Civil Rights Act: Prohibits discrimination based on race, color, religion, sex, or national origin
• Americans with Disabilities Act (ADA): Requires reasonable accommodations for qualified individuals with disabilities
• Pregnancy Discrimination Act: Prohibits discrimination based on pregnancy
• Genetic Information Nondiscrimination Act (GINA)

20 or More Employees

• Age Discrimination in Employment Act (ADEA): Protects employees age 40 and older

50 or More Employees

• Affordable Care Act (ACA) employer mandate: Must offer health insurance to full-time employees

Wage and Hour Compliance

Minimum Wage

You must pay at least the highest applicable minimum wage (federal, state, or local). As of 2025, many states have minimum wages significantly above the federal $7.25 rate. Some cities have rates above $18 per hour.

Overtime

Non-exempt employees must receive overtime pay (1.5x regular rate) for hours worked beyond 40 in a workweek. Common exemptions apply to executive, administrative, professional, and certain computer employees, but only if they meet specific salary and duties tests.

Pay Frequency and Method

Most states require employers to pay employees on a regular schedule (weekly, biweekly, or semi-monthly). Some states restrict payment methods or require employers to offer direct deposit as an option. Check your state's requirements.

Recordkeeping

The FLSA requires employers to maintain records for each non-exempt employee, including:

• Hours worked each day and total hours each week
• Regular hourly rate and total overtime pay
• Total wages paid each pay period
• Pay period dates

Keep these records for at least three years.

Workplace Safety (OSHA)

Your Basic Obligations

• Provide a workplace free from recognized hazards
• Post the OSHA "Job Safety and Health" poster
• Report fatalities within 8 hours and serious injuries within 24 hours
• Maintain an OSHA 300 Log of work-related injuries and illnesses (if you have 11+ employees)
• Provide required safety training for your industry

Common Violations for Small Businesses

The most frequently cited OSHA violations include fall protection, hazard communication, scaffolding, respiratory protection, and lockout/tagout procedures. Even office-based businesses must address ergonomics, fire safety, and emergency exits.

Anti-Discrimination and Harassment

Creating a Compliant Workplace

Every employer should have:

• A written anti-discrimination and anti-harassment policy
• A clear reporting procedure for complaints
• Regular training for managers and employees (required by law in several states)
• A consistent process for investigating complaints

State-Level Protections

Many states extend anti-discrimination protections beyond federal law. Some cover businesses with fewer than 15 employees. Common additional protected categories include sexual orientation, gender identity, marital status, and political affiliation.

Termination and Separation

At-Will Employment

Most states follow at-will employment, meaning either the employer or employee can end the relationship at any time, for any legal reason. However, you cannot terminate someone for a discriminatory or retaliatory reason.

Final Paycheck Requirements

State laws vary significantly on when you must deliver a final paycheck:

• Some states require immediate payment upon termination
• Others allow until the next regular payday
• Unused vacation payout requirements also vary by state

Documentation

Always document performance issues, warnings, and the reason for termination. Good documentation is your best protection against wrongful termination claims.

Practical Steps to Get Started

• Create an employee handbook covering your policies, expectations, and legal notices
• Post all required workplace notices (federal and state posters are available free from the DOL)
• Set up proper payroll with tax withholding, benefits deductions, and recordkeeping
• Get workers' compensation insurance (required in nearly every state)
• Consult an employment attorney for your state-specific obligations, especially if you are in a heavily regulated industry
