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.

Common Waiting Period Choices Among Florida Employers

Waiting PeriodWhen Coverage StartsCommon Use Case
No waiting period (day 1)First day of employmentHigh-demand professional roles; recruiting advantage
30 daysFirst of month after 30 daysOffice-based businesses; professional services
60 daysFirst of month after 60 daysBalanced approach; most common in small groups
90 daysFirst 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.

Planning tip: If you have a key hire who needs immediate coverage, many carriers allow a hire-date effective start if your plan's waiting period is "day 1." Discuss this option when setting up your plan — it gives you flexibility to waive the waiting period for specific circumstances.

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:

ACA Compliance: What Can't You Do?

A few waiting period practices that are not permitted under ACA rules:

ALE Note: If your Florida business is an Applicable Large Employer (50+ FTEs), failure to offer coverage by day 91 of employment (including the waiting period) can result in ACA penalties — approximately $4,350/year per full-time employee not offered coverage in 2026.

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.

Frequently Asked Questions

Can we have different waiting periods for different positions (e.g., 0 days for managers, 90 days for hourly staff)?
Yes — you can have different waiting periods for different employee classes (e.g., full-time salaried vs. full-time hourly, or management vs. non-management) as long as the classification is based on legitimate employment criteria and doesn't discriminate on protected characteristics. The classification must be documented in your plan documents and applied consistently. Each class's waiting period must still be 90 days or less.
A new hire asked if she can enroll in the plan before her 60-day waiting period ends because she's pregnant. Do we have to let her in early?
No — a waiting period is uniformly applied and you're not required to waive it for health status reasons. However, ACA does prohibit pre-existing condition exclusions on all ACA-compliant plans — so once she's enrolled after the waiting period, her pregnancy (which predates enrollment) is fully covered. Many Florida employers waive the waiting period voluntarily for key hires in circumstances like this, but it's at the employer's discretion.
If a new employee misses the enrollment window after their waiting period, when can they enroll?
If an employee doesn't enroll during their initial eligibility window (typically 30 days after the waiting period ends), they must wait for the plan's next annual open enrollment period — usually October/November for a January 1 restart. The exception is a qualifying life event (marriage, birth, loss of other coverage), which triggers a Special Enrollment Period outside of open enrollment.
We're setting up our first group plan. What waiting period should we use?
For most Florida small businesses, we recommend 30 or 60 days. A 30-day waiting period is easy to communicate and minimizes the coverage gap for new hires who prioritize benefits. Sixty days balances employee interest with the practical reality that some early hires don't stay. Industries with higher turnover (restaurants, retail) often use 90 days. Professional services often use 30 days or day 1 as a competitive signal in their recruiting.
