The ACA Waiting Period Rule: 90-Day Maximum
Under the Affordable Care Act, employers that offer group health insurance cannot impose a waiting period longer than 90 calendar days from the date an employee is otherwise eligible for coverage. This rule applies to all ACA-compliant group health plans in Florida, regardless of company size.
Key definitions:
- Waiting period: The period that must elapse before coverage becomes effective for an otherwise eligible employee
- 90 calendar days: Not business days — calendar days from the eligibility date
- Eligibility date: The date the employee meets your plan's eligibility criteria (typically the hire date or the date they reach full-time status)
Common Waiting Period Choices Among Florida Employers
| Waiting Period | When Coverage Starts | Common Use Case |
|---|---|---|
| No waiting period (day 1) | First day of employment | High-demand professional roles; recruiting advantage |
| 30 days | First of month after 30 days | Office-based businesses; professional services |
| 60 days | First of month after 60 days | Balanced approach; most common in small groups |
| 90 days | First of month after 90 days (or day 91) | Higher-turnover industries; cost management |
In our experience with Florida small businesses, 30 or 60 days is the most common waiting period. Ninety days is more typical in industries with higher early turnover, like restaurants and retail. Professional services firms (law, accounting, medical) often use 30 days or no waiting period as a recruiting signal.
First-of-Month Effective Date Convention
Most Florida carriers use a first-of-the-month effective date for new enrollments. This means if your plan has a 30-day waiting period and an employee is hired on March 15, they become eligible April 14, and their coverage typically starts May 1 (the first of the month after eligibility). This can effectively extend a 30-day waiting period to 45–60 days depending on the hire date timing.
What Happens During the Waiting Period?
During the waiting period, the new employee is uninsured (unless they have coverage from another source). Options for employees in the gap period:
- COBRA from prior employer: If the employee was previously on a group plan, they can elect COBRA coverage during the gap. COBRA is expensive — they pay the full premium plus a 2% administrative fee — but provides continuity.
- ACA Special Enrollment: Losing job-based coverage triggers a Special Enrollment Period (SEP) on HealthCare.gov. New employees can use the SEP at their prior employer to enroll in a marketplace plan during the gap.
- Short-term health insurance: Florida allows 12-month short-term health plans, which can provide gap coverage at lower cost than COBRA but with limited benefits.
- Spouse/parent plan: If the employee has access to coverage through a spouse's or parent's employer, this may bridge the gap.
ACA Compliance: What Can't You Do?
A few waiting period practices that are not permitted under ACA rules:
- Waiting period longer than 90 days for otherwise eligible full-time employees
- Conditioning eligibility on completing an orientation period beyond 30 days (orientation + waiting period combined cannot exceed 90 days for ALE purposes)
- Applying different waiting periods to employees based on age, disability, or other protected characteristics
- Using health status as a condition of eligibility or imposing pre-existing condition exclusions (prohibited under ACA)
Variable-Hour Employees: The Measurement Period
For employees who don't have a predetermined number of weekly hours (e.g., part-time, variable-hour, or seasonal employees), ACA regulations allow employers to use a "look-back measurement period" of 3–12 months to determine if the employee averaged 30+ hours/week and therefore qualifies as full-time. Once determined to be full-time, the employee must be offered coverage within an administrative period not exceeding 90 days. This is primarily relevant for ALEs.
