Overtime pay is the additional compensation owed to nonexempt employees when they work more than 40 hours in a workweek. In most cases, the federal Fair Labor Standards Act (FLSA) requires employers to pay these employees at 1.5 times their regular rate for each hour worked beyond 40. Some states have their own overtime rules that may provide additional protections or use different thresholds.

Employers are responsible for correctly classifying employees as exempt or nonexempt. Misclassification can lead to compliance issues, back pay obligations and penalties. Overtime calculations must also include compensation that counts toward an employee’s regular rate of pay, such as hourly wages and nondiscretionary bonuses.

Because overtime rules affect payroll accuracy, labor costs and compliance, human resources (HR) and payroll teams need clear timekeeping practices and consistent pay calculations.

Employee Classification: Exempt vs. Non-Exempt

Employee classification helps determine who qualifies for overtime pay. Under the FLSA, exempt and nonexempt status is based on job duties and how an employee is paid, not job title alone.

Exempt employees are not eligible for overtime pay. These employees often work in executive, administrative, professional or outside sales roles and must meet specific salary and duties tests.

Non-exempt employees are generally eligible for overtime pay. In most cases, they must receive 1.5 times their regular rate of pay for hours worked over 40 in a workweek.

When reviewing roles for proper classification, employers should:

• Evaluate actual job duties against exemption tests provided by the U.S. Department of Labor (DOL)

• Confirm the employee meets or exceeds the salary or hourly pay rate thresholds

• Verify the number of hours worked, particularly if they exceed 40 in a workweek

• Account for specific overtime pay requirements under both federal and state overtime laws

Accurate classification helps employers apply overtime rules correctly and reduce the risk of disputes or penalties.

State Overtime Rules

Federal law sets the baseline for overtime pay, but some states apply broader or more detailed overtime requirements. These differences may affect when overtime applies, how it is calculated and whether additional premiums are required.

Some states require overtime after a certain number of hours worked in a single day, not just after 40 hours in a workweek. For example, in California, non-exempt employees must receive overtime pay after working more than eight hours in a day, regardless of their total weekly hours. Some states also require double time after employees work beyond a higher daily threshold.

States may also have different rules on:

• How compensatory time is treated for public sector employees

• Whether agricultural or healthcare workers are covered by specific exemptions

• Which employees qualify for overtime based on earnings or duties beyond federal criteria

These differences matter for employers operating in more than one state. Applying federal rules alone may not be enough. Employers should review state labor department guidance to confirm current requirements.

Risks of Non-Compliance

Failing to comply with overtime pay requirements can lead to legal, financial and operational consequences. The DOL investigates wage-and-hour violations and may pursue back pay, damages and penalties for unpaid overtime compensation.

Common issues leading to non-compliance include:

• Not tracking the total number of overtime hours accurately

• Relying on job titles instead of duties to determine exemption

• Using an incorrect regular hourly rate when calculating premium pay

• Applying compensatory time in the private sector where it is not allowed

In some cases, claims can extend across multiple pay periods and cost far more than the unpaid overtime itself. Regular reviews of classifications, timekeeping practices and pay calculations help reduce risk.

Strategic Implications

Overtime pay affects more than compliance. It also influences labor costs, scheduling and employee workload.

Frequent overtime may indicate understaffing, scheduling problems or uneven workload distribution. Tracking overtime by department or role can help employers spot patterns early and make better staffing decisions.

To manage overtime more effectively, employers can:

• Use workforce analytics to track total hours worked and forecast overtime trends

• Set internal thresholds or approval workflows to manage unscheduled overtime

• Educate supervisors on proper time tracking and overtime pay requirements

• Review pay policies regularly to align with current overtime laws

Treating overtime as a managed cost center, not just a payroll line item, gives HR and finance better control over total pay and workload distribution. It also supports fair compensation practices and reduces the risk associated with unplanned overtime.
