Seasonal Employees and the ACA: Common Compliance Mistakes

Hiring seasonal workers is a routine part of business for many employers, especially during the summer, holiday season, or periods of increased demand. However, one of the most common Affordable Care Act (ACA) compliance mistakes is assuming that all seasonal employees can be treated the same way for benefits eligibility purposes.

Although the terms “seasonal employee” and “variable-hour employee” are often used interchangeably, they are not the same. Misclassifying employees can lead to incorrect benefit offers, reporting errors, and potential employer shared responsibility penalties.

Seasonal vs. Variable-Hour Employees

A seasonal employee is generally hired into a position that is expected to last only during a particular season or recurring period, such as summer recreation staff, holiday retail employees, or specific harvest workers.

A variable-hour employee, on the other hand, is an employee whose hours cannot reasonably be determined at the time of hire. The focus is not on how long the employee will work, but whether the employer can determine if the employee is expected to average at least 30 hours of service per week.

An employee may be both seasonal and variable-hour, but not every seasonal employee is variable-hour, and not every variable-hour employee is seasonal.

Common Employer Mistakes

One common mistake is automatically classifying every seasonal hire as variable-hour. If an employer reasonably expects a seasonal employee to work full-time for the duration of the assignment, that employee may need to be treated as a full-time employee for ACA purposes.

Another issue occurs when employers fail to monitor hours worked. Seasonal employees sometimes remain employed longer than originally anticipated or consistently work full-time schedules. If actual hours differ from initial expectations, employers should review whether their ACA eligibility determinations remain appropriate.

Employers also encounter problems when seasonal employees return year after year. Depending on the length of the break in service and the employer’s ACA measurement method, returning employees may need to be treated differently than new hires.

Finally, inconsistent classifications between HR, payroll, and benefits administration systems can create reporting errors. An employee classified one way for payroll and another for ACA administration can lead to inaccurate Forms 1095-C and increase the likelihood of IRS inquiries.

Best Practices

Employers can reduce ACA compliance risks by:

• Documenting the expected work schedule and duration at the time of hire.
• Monitoring actual hours worked throughout the employment period.
• Reviewing employees whose assignments are extended beyond the original expectation.
• Applying measurement period rules consistently.
• Coordinating HR, payroll, and benefits administration records to ensure employee classifications remain accurate.

The Bottom Line

Seasonal hiring provides valuable flexibility, but it also requires careful ACA administration. Employers should evaluate each employee based on the expected facts and circumstances at the time of hire rather than relying solely on a job title or seasonal designation. Periodic reviews of employee classifications and hours worked can help prevent costly compliance mistakes and improve the accuracy of ACA reporting.
