Classification looks like a paperwork question until it isn't. A single misclassified contractor who should have been an employee can cost a company six figures in back payroll taxes, unpaid overtime, and benefits retroactivity. The DOL and IRS have both escalated enforcement in recent years, and state agencies are often more aggressive than federal ones. This page covers the main employee types, the tests regulators use to distinguish them, and the specific areas where classification mistakes are most common and most expensive.
The Main Employee Types
Full-time employees work a regular schedule (usually 30+ hours per week) and receive the company's standard benefits package: health insurance, retirement plan eligibility, PTO, and so on. Part-time employees work fewer hours and may or may not qualify for benefits depending on company policy and ACA rules (employees working 30+ hours per week on average are considered full-time under the Affordable Care Act).
Temporary employees are hired for a defined period, often through a staffing agency, and typically don't receive company benefits. Seasonal employees work during specific parts of the year (retail holiday season, summer camp, tax season) with an understanding the role ends. Independent contractors aren't employees; they run their own business and receive a 1099 rather than a W-2.
How Employee Classification Affects Pay and Benefits
Classification drives payroll tax treatment, benefits eligibility, overtime exposure, and leave rights. Full-time and part-time employees both receive W-2s, with payroll taxes (FICA, federal withholding) deducted from each paycheck. Contractors receive FICA -free 1099 payments and handle their own self-employment tax.
Classification also determines overtime status. Non-exempt employees must receive overtime for hours over 40 per week; exempt employees don't. The Fair Labor Standards Act salary threshold for exempt status sits at $58,656 annually (Department of Labor salary threshold, which has been subject to ongoing rulemaking). Confirm the current threshold with the DOL FLSA page before making classification decisions.
Who Decides If an Employee Is Exempt or Non-Exempt?
The company does the initial classification, but the DOL and courts can overturn it. Exempt status requires meeting both the salary threshold and a duties test (executive, administrative, professional, computer, or outside sales). A high-salary employee who doesn't meet the duties test is still non-exempt, and owed overtime.
Contractor vs. Employee: Where Companies Get Burned
Calling someone a contractor doesn't make them one. The IRS uses a multi-factor test covering behavioral control (does the company direct how the work gets done?), financial control (who supplies tools and bears the risk of profit/loss?), and relationship type (is there a written contract, benefits, ongoing relationship?). California, New Jersey, Massachusetts, and several other states apply an even stricter ABC test that presumes employee status unless all three prongs are met.
Misclassification penalties include back payroll taxes, unpaid overtime, benefits retroactivity, and fines. The DOL Wage and Hour Division recovered hundreds of millions in back wages from misclassification cases in recent years. The IRS classification guidance is the first place to check before making a contractor decision.
Getting Employee Type Right in Your HRIS
Configure your HRIS to require a classification decision at hire with the rationale documented. Review classifications quarterly, especially for long-tenure contractors (over 12 months is a yellow flag) and remote workers across state lines (state tests can differ from federal). Include classification as a standard check during annual compensation reviews and at any role change.
When in doubt, classify conservatively (as an employee) and consult employment counsel before reversing. The cost of reclassifying an employee as a contractor is almost zero; the cost of reclassifying a contractor as an employee, retroactively, can be enormous. Build the classification discussion into your standard hiring and performance review workflows so it doesn't get skipped.
