For Florida employers, ACA compliance comes down to a handful of dates and one percentage. The percentage is the 2026 affordability threshold — 9.96%, the highest it has ever been — and the dates govern when you furnish and file your reporting forms. Miss them and the penalties are real: the 2026 employer-mandate penalties run $3,340 (no-offer) and $5,010 (unaffordable-offer) per affected employee.
The first question is whether you are an Applicable Large Employer (ALE): an employer that averaged 50 or more full-time-equivalent employees in the prior year. ALEs carry the mandate and the reporting burden. This 2026 checklist walks the determination, the affordability test, and the filing calendar.

The Mistake That Catches Growing Employers
The most common compliance failure in Florida is a business crossing the 50-FTE line without realizing it. ALE status is based on the prior calendar year's average, and it counts full-time-equivalents, not just full-time heads — two half-time employees equal one FTE. A seasonal Florida business (hospitality, agriculture, tourism) can tip over 50 FTEs on paper even if it never feels "large." Once you are an ALE, the mandate and 1095-C reporting apply whether or not you knew.
Step 1 — Determine ALE Status
- Add full-time employees (30+ hours/week) plus full-time equivalents (part-time hours ÷ 120 per month).
- Average the monthly totals across the prior year.
- 50 or more = ALE for the current year. A seasonal-worker exception may apply if you only exceed 50 for 120 days or fewer.
Step 2 — Offer Affordable, Minimum-Value Coverage
An ALE must offer minimum essential coverage to at least 95% of full-time employees and their dependents, and that coverage must be both affordable and provide minimum value. For 2026, coverage is affordable if the employee's required contribution for self-only coverage does not exceed 9.96% of household income — measured in practice through one of three safe harbors (W-2 wages, rate of pay, or federal poverty line).
| 2026 Employer Mandate Penalty | Amount | Trigger |
|---|---|---|
| 4980H(a) — "no offer" | $3,340 per FT employee (minus 30) | Failing to offer MEC to 95% of FT staff |
| 4980H(b) — "unaffordable" | $5,010 per subsidized employee | Offer is unaffordable or not minimum value |
The 4980H(a) penalty is the harsher of the two because it multiplies across nearly your entire full-time workforce; 4980H(b) applies only per employee who actually receives a marketplace subsidy.
Step 3 — Meet the 2026 Reporting Deadlines
- Furnish 1095-C to employees: by March 2, 2026. Under current rules you may instead post a clear website notice that employees can request the form, keeping it available through October 15, 2026.
- File 1094-C / 1095-C with the IRS: paper by February 28, 2026; electronically by March 31, 2026.
- E-filing is mandatory if you file 10 or more information returns in aggregate — and the 10-count now combines your W-2s, 1099s, and ACA forms together. In practice almost every ALE must e-file.
Because the 10-return threshold aggregates all your information returns (W-2s, 1099s, 1094-C/1095-C), even a small ALE almost certainly clears 10 and must e-file. Paper filing is no longer an option for most employers.
The Florida Angle
ACA employer compliance is entirely federal — there is no Florida state-level ACA reporting layer, unlike states such as California, New Jersey, and Massachusetts that run their own individual-mandate reporting regimes requiring separate state filings. A Florida employer files only the federal 1094-C/1095-C set, with no parallel state submission. That makes Florida one of the simpler states for ACA reporting logistics. The flip side: Florida did not expand Medicaid, so more lower-income Florida workers rely on subsidized marketplace coverage — which means an unaffordable employer offer is more likely to send an employee to a subsidized exchange plan and trigger a 4980H(b) penalty. Affordability discipline matters more here, not less.
Common Mistakes to Avoid
- Missing ALE status after growth. Recheck the prior-year FTE average every year.
- Using the wrong affordability safe harbor. Pick W-2, rate-of-pay, or FPL deliberately and apply it consistently.
- Late or paper filing. E-file by March 31, 2026; most ALEs are required to e-file.
- Forgetting dependents. The 95% offer must include dependents, not just employees.
- Ignoring the website-notice rules. If you use the alternative furnishing method, the notice must be posted on time and kept accessible.

Recordkeeping and the Measurement-Period Method
The hardest part of ACA compliance for Florida employers with variable-hour staff — common in hospitality, tourism, and home health — is determining who counts as full-time. The look-back measurement method solves this: you track hours over a defined measurement period (typically 3 to 12 months), then lock in each employee's full-time status for a corresponding stability period regardless of hour fluctuations. This shields you from month-to-month churn pushing workers in and out of full-time status. Pair it with disciplined recordkeeping: hours worked, coverage offers and their dates, employee contributions, and the specific 1095-C line-14 and line-16 codes that document each month's offer and any safe harbor. Those codes are where most reporting errors occur. Keep records for at least three years and reconcile them before the March furnishing and filing deadlines. A clean measurement method plus accurate coding is what turns ACA reporting from a scramble into a routine.
