FLSA Exempt vs Non-Exempt: The Most Expensive Misclassification in US Payroll

The US Fair Labor Standards Act turns 87 years old this year and still produces more class-action lawsuits than any other federal employment statute. The reason is simple: classifying an employee as "exempt" from overtime pay when the role does not actually meet the FLSA's tests creates retroactive wage liability that the Wage and Hour Division will calculate going back two or three years.

The three tests every exempt employee must pass

To be lawfully exempt from overtime, an employee must clear all three of:

1. Salary basis test. Paid a predetermined fixed salary that is not subject to reduction based on quality or quantity of work.
2. Salary level test. Earn above the federal threshold — currently $684/week ($35,568/year). The 2024 increase to $1,128/week was vacated by a federal court in late 2024; the threshold reverted to the 2019 level pending further rulemaking.
3. Duties test. Primarily perform executive, administrative, professional, computer, or outside sales duties as defined in 29 CFR Part 541.

State law often adds layers on top. California's salary threshold is roughly twice the federal one, New York and Washington both run higher numbers, and several states have their own duties definitions.

Where teams misclassify

The four highest-risk titles in our experience advising US clients:

• "Assistant manager" in retail or hospitality. If they are spending 50%+ of their time doing the same tasks as hourly staff (cashier, server, cook), they are likely non-exempt regardless of title.
• "Account executive" early in tenure. If they do not have independent discretion on customer accounts and largely follow scripted workflows, they may not pass the administrative duties test.
• IT support staff under the computer exemption. Tier-1 helpdesk roles rarely meet the "systems analysis or programming" requirements.
• Independent contractors who are really employees. See our W-2 vs 1099 explainer for the modern Department of Labor test.

For role-by-role guidance, the DOL's overtime portal publishes fact sheets for each exemption.

How HR systems help (or hide) the problem

A well-configured HR system should hold a documented exemption rationale for every salaried employee — which exemption applies, which duties qualify, who approved the classification, when it was last reviewed. The FLSA glossary entry goes into the duties tests in more depth, and our PTO calculator handles accrual differences between exempt and non-exempt staff for organisations that grant time off on different schedules.

Beyond the federal floor, the Bureau of Labor Statistics publishes annual wage data by occupation and metropolitan area that is useful for sanity-checking salary thresholds in jurisdictions where state law layers in.
