Under the Fair Labor Standards Act, all non-exempt employees are entitled to overtime pay at 1.5x their regular rate for hours worked beyond 40 in a workweek. Employees are either exempt or non-exempt based on job duties and salary level. The primary exemptions are the executive, administrative, professional, computer, and outside sales exemptions — often called the white-collar exemptions. To qualify for exemption, employees must generally meet both a duties test (the job must involve a certain type of work) and a salary level test. As of July 2024, the DOL raised the exempt salary threshold to $844/week ($43,888/year), with a further increase to $1,128/week ($58,656/year) effective January 1, 2025. Employees below these thresholds are automatically non-exempt and entitled to overtime regardless of job title or duties.

The regular rate of pay for FLSA overtime purposes must include: base hourly or salary wages, non-discretionary bonuses (bonuses tied to productivity, attendance, or performance metrics that employees can expect), shift differentials, and most commission payments. It excludes: truly discretionary bonuses (where the employer has unfettered discretion over whether to pay them), gifts, vacation and holiday pay, overtime premiums already paid, and expense reimbursements. Employers commonly make errors by calculating overtime based on base wage alone without including non-discretionary bonuses, which can result in significant back-pay liability in DOL investigations or class-action wage lawsuits.

Overtime pay is subject to the same payroll taxes as regular wages: federal income tax withholding, Social Security (6.2% employer share), Medicare (1.45% employer share), and state/local payroll taxes where applicable. The employer's payroll tax cost on overtime is proportional — more overtime pay means more payroll tax expense. However, benefits costs (health insurance, 401(k) match based on a fixed dollar amount) do not increase proportionally with overtime hours, which means the benefits burden rate on overtime hours is lower than on regular hours. This is why some employers find limited overtime slightly cheaper per productive hour than the same hours worked by a new employee who receives full benefits.

FLSA violations can be costly. Employees who are not paid required overtime are entitled to recover all unpaid wages plus an equal amount in liquidated (double) damages, plus reasonable attorney's fees. The DOL Wage and Hour Division can investigate complaints and assess back-pay plus penalties. For willful violations, the statute of limitations extends from 2 years to 3 years. Class-action lawsuits for overtime misclassification are among the most common employment law claims — cases in industries like retail, restaurant, mortgage services, and trucking have resulted in settlements of tens of millions of dollars. State laws can impose additional penalties: California, for example, imposes waiting time penalties of up to 30 days of wages for employees whose final paycheck is late or incorrect.

Compensatory time off (comp time) — giving extra paid time off instead of cash overtime pay — is legal for state and local government employers under the FLSA. However, private-sector employers generally cannot substitute comp time for cash overtime payment. A private employer cannot tell a non-exempt employee they will receive an extra day off instead of overtime pay for hours worked beyond 40 in a workweek. The only limited exception involves averaging hours across a 2-week period for certain hospital and residential care employees under a specific FLSA provision (Section 7(j)). Violating this rule constitutes an FLSA overtime violation.

Effective overtime management requires both tracking and proactive scheduling. First, implement a time and attendance system that flags overtime before it occurs, allowing managers to adjust schedules or redistribute work. Second, require manager pre-approval for overtime, making the cost visible and deliberate rather than automatic. Third, analyze overtime patterns by department, shift, and individual — chronic overtime in specific teams often indicates understaffing, inefficient workflow, or excessive absenteeism. Fourth, model the break-even point: at what level of recurring weekly overtime hours does it become more cost-effective to hire? Typically, if overtime consistently exceeds 5 hours/employee/week for more than 12 weeks, a staffing solution is economically justified.

Yes, the FLSA contains numerous exemptions beyond the standard white-collar exemptions. Agricultural workers have different overtime thresholds. Truck drivers, railroad workers, airline employees, and certain seamen are covered by the Motor Carrier Act or Railway Labor Act rather than FLSA overtime provisions. Outside salespeople are exempt from overtime if they primarily work away from the employer's place of business making sales. Certain highly compensated employees (earning $107,432 or more annually under 2024 rules) qualify for a simplified exemption test. Live-in domestic workers, certain seasonal amusement park employees, and fishing industry workers also have special rules. State laws may provide broader protections that override these federal exemptions.
