Florida has one of the most seasonal economies in the country. Tourism, agriculture, construction, hospitality, and retail all have significant seasonal employment patterns. If your small business relies heavily on seasonal workers, understanding how the ACA and Florida's insurance market treat seasonal employment is essential — both to manage your costs and to avoid compliance surprises.
What Is a "Seasonal Employee" Under the ACA?
The ACA and IRS define a seasonal employee as someone hired for a position that the employer reasonably anticipates will last six months or fewer, and that begins at approximately the same time each year. This is not simply any temporary worker — the key elements are:
- The work is expected to last six months or fewer (at time of hire)
- The position occurs at roughly the same period each year (e.g., summer tourism season, November–April snowbird season)
Seasonal employees who meet this definition may be excluded from certain ACA calculations, including the ALE (Applicable Large Employer) FTE determination for periods where seasonal workers push you over 50 FTEs temporarily.
The Seasonal Worker Exception to the ALE Threshold
Under ACA Section 4980H, if you have fewer than 50 FTEs for at least 6 months of the year, you are not an ALE even if your workforce exceeds 50 FTEs in the remaining months — provided the excess is due to seasonal workers. This is the "seasonal worker exception."
Example: A Florida beach resort has 35 year-round employees and adds 20–25 seasonal staff from March through August. During season, they exceed 50 FTEs. But because the excess is entirely seasonal workers, and because they have fewer than 50 FTEs for 6+ months of the year, they qualify for the seasonal worker exception and are not an ALE. No ACA mandate applies.
The 120-Day Rule for Seasonal Employees
For employers who are not ALEs, the 120-day rule provides that an employee who works fewer than 120 days per calendar year may be treated as a seasonal worker for ACA purposes, even if they work more than 30 hours per week during their active period. This affects how you classify them for benefits eligibility.
However, this rule is specifically for non-ALE employers assessing their ALE status — it doesn't automatically mean you can exclude them from your group health plan if you've set a different eligibility standard. Your plan document governs who must be offered coverage within the constraints of ACA rules and your carrier's participation requirements.
Look-Back Measurement Period for Variable Seasonal Staff
For employees who return each season but have fluctuating hours, the look-back measurement period allows you to:
- Measure hours over a defined period (3–12 months)
- Determine whether the employee averages 30+ hours/week
- Apply a stability period where their classification is locked regardless of actual hours
For a returning seasonal worker who works the same 5-month season each year, using a 12-month measurement period would typically show an average below 30 hours/week when the non-working months are included. This means they legitimately classify as part-time for benefits purposes even if they work 40+ hours/week during their active period.
| Employee Type | Measurement Approach | Likely Classification |
|---|---|---|
| 5-month seasonal (same period each year) | 12-month look-back | Part-time (average 20 hrs/week annualized) — can exclude |
| Returning seasonal, 8 months active | 12-month look-back | May average 30+ hrs/week annualized — review required |
| New seasonal hire, first season | Initial measurement period from hire | Review after initial period before stability begins |
| Year-round with seasonal peak hours | Standard 12-month measurement | Likely full-time if baseline hours are 30+ |
Florida-Specific Seasonal Industries and Coverage Approaches
Tourism / Hospitality (Gulf Coast, Atlantic Coast, Keys)
Peak season is October–April in most South and Gulf Coast markets. Core year-round staff (managers, leads) are your covered group. Seasonal staff hired explicitly for season are excluded. Returning seasonal workers who come back every year for 5–6 months use the 12-month look-back — typically classifying as part-time when months off are included in the average.
Agriculture (Central and South Florida)
Florida's agricultural seasonal workers present complex classification questions. Many are H-2A visa holders (temporary agricultural workers) who have specific visa-related coverage rules and are not eligible for group plans on the same basis as domestic employees. Domestic seasonal agricultural workers follow standard ACA measurement rules. Consult an employment attorney familiar with agricultural workforce rules before structuring coverage here.
Outdoor Recreation and Marine Tourism (Keys, Panhandle)
Charter boat captains, fishing guides, diving instructors — seasonal in timing but often the same individuals returning each year. If they're W-2 employees, the look-back method applies. If they're independent contractors (1099), they cannot participate in the group plan regardless.
Construction (Post-Storm and Cyclical)
Florida's construction boom is largely year-round, but some contractors have seasonal project cycles. Laborers hired for specific projects that last under 120 days may qualify for seasonal exclusion. Project-based W-2 workers who work year-round on sequential projects are not seasonal — the measurement period would show them as full-time.
What Seasonal Workers Can Do for Their Own Coverage
When seasonal employment ends, workers have options:
- COBRA: If they were enrolled in your group plan, they can continue coverage for up to 18 months at their own cost (full premium plus 2%)
- ACA Special Enrollment Period: Loss of employer coverage triggers a 60-day SEP to purchase marketplace coverage; they may qualify for premium tax credits if their seasonal income puts them within marketplace subsidy range
- Short-term plans: Available in Florida for gaps up to 36 months; limited benefits, not ACA-compliant, but provide some financial protection during the off-season
- Medicaid: If their off-season income drops below 138% FPL (~$20,000/year for a single person in 2026), they may qualify for Florida Medicaid — though Florida's Medicaid expansion status affects this
- We bring back the same 10 people every tourist season. After 3–4 years, are they still "seasonal"?
- Under the IRS definition, returning workers hired into a position that reasonably lasts 6 months or fewer and occurs at the same time each year continue to qualify as seasonal workers. The fact that they return multiple years doesn't change the classification — what matters is whether each hiring instance is for a defined seasonal period. Document each re-hire with a clear offer letter specifying the seasonal nature and expected end date.
- A seasonal worker got injured during the off-season. Does that affect our plan?
- If the seasonal worker is not enrolled in your group plan (because they were excluded as seasonal), their off-season injury has no impact on your plan. If they had COBRA continuation coverage, the claim goes through COBRA. Your group plan is unaffected by events occurring while a person is not enrolled.
- Our business is slow in summer. Does the ALE calculation use our peak or average headcount?
- ALE status is determined using the average of your monthly FTE counts across all 12 months of the prior calendar year. A business that has 35 employees in January–May and 60 employees in June–December (a very unusual pattern for Florida) would average approximately 51.25 FTEs and would be an ALE. More commonly, Florida businesses are below 50 in summer and peak in winter — making the year-round average below 50 for most small operators.
