If your South Florida business grew its headcount in 2026, you might owe the IRS a set of forms you have never filed before. Becoming an applicable large employer, or ALE, triggers Affordable Care Act reporting requirements that catch many growing Miami-Dade companies off guard every filing season. The forms are due in early 2027, the penalties for missing them are steep, and the determination of whether you even qualify is more nuanced than simply counting heads on your payroll.

This guide walks you through exactly how to determine applicable large employer status, which ACA forms you need to file, the deadlines you cannot miss, and what it actually costs if you get it wrong. Whether you run a restaurant group in Coral Gables, a professional services firm in Brickell, or a growing medical practice in Kendall, understanding your ACA reporting small business obligations now will save you from a scramble (and potential penalties) come January.

What Is an Applicable Large Employer Under the ACA

An applicable large employer is a business that employed an average of at least 50 full time employees, including full time equivalent employees, during the prior calendar year. This is a federal determination under Internal Revenue Code Section 4980H, and it applies regardless of your business structure, whether you operate as an S corporation, partnership, or sole proprietorship with employees.

The key phrase is "full time equivalent." The IRS does not just count your 50 full time workers. It requires you to add in a calculation based on your part time staff's hours to determine if, combined, your workforce crosses the 50 full time employees threshold.

How the Full Time Equivalent Calculation Works

A full time employee is defined as someone who works an average of at least 30 hours per week, or 130 hours per month. To calculate your full time equivalents from part time staff, you take the total monthly hours worked by all part time employees (capped at 120 hours per employee per month) and divide by 120.

Here is a real world example. Suppose your Coral Gables based marketing agency has 42 full time employees and 16 part time employees who each average 80 hours per month in 2026.

1. Total part time hours: 16 employees x 80 hours = 1,280 hours per month
2. Divide by 120: 1,280 / 120 = 10.67, rounded down to 10 full time equivalents
3. Add to full time count: 42 + 10 = 52

Because 52 exceeds the 50 full time employees threshold, this agency is an applicable large employer for the 2027 filing season, even though it only has 42 employees who work a traditional 40 hour week. This calculation must be done for each month of 2026 and averaged across the year, with seasonal workforce fluctuations factored in (there is a seasonal worker exception if your headcount only exceeds 50 for 120 days or fewer).

Why This Matters So Much for South Florida Growing Businesses

South Florida's economy is full of businesses that straddle this 50 employee line: hospitality groups, construction contractors, medical and dental practices, and professional services firms that staff up seasonally for tourist season or hurricane recovery work. Miami-area entrepreneurs often cross into ALE status without realizing it, particularly after an acquisition, a seasonal hiring surge, or simply organic growth.

Unlike many tax determinations, ACA applicable large employer status is not optional or elective. Once you cross the threshold based on your prior year average, you are locked into ALE reporting obligations for the following calendar year, regardless of whether your headcount later drops. If you crossed 50 full time equivalent employees at any point during 2026, you are an ALE for 2027 reporting purposes and must file the corresponding forms by the early 2027 deadlines discussed below.

ACA Forms You Must File as an Applicable Large Employer

Once you have confirmed ALE status, you have two distinct filing obligations, one for your employees and one for the IRS.

Form 1095-C: Employee Statements

Form 1095-C, the Employer Provided Health Insurance Offer and Coverage statement, must be furnished to every full time employee who worked for you at any point during 2026. This form reports:

• Whether you offered minimum essential coverage to the employee and their dependents
• The lowest cost monthly premium available to the employee
• Which months the employee was actually enrolled in coverage
• Codes identifying your offer of coverage under IRS Section 4980H safe harbors

Form 1094-C: Transmittal to the IRS

Form 1094-C is the transmittal form that accompanies all of your 1095-C forms when you submit them to the IRS. Think of it as the cover sheet that summarizes your total employee count, aggregated group information if you are part of a controlled group, and certification of eligibility for any transition relief.

Most South Florida small and mid-size businesses that provide fully insured health coverage through a carrier will rely on that carrier to issue Form 1095-B to covered individuals, while the employer remains responsible for 1095-C and 1094-C filings. If your business is self-insured, you have additional reporting responsibility on the 1095-B side as well.

Step by Step: Filing Your 2026 ACA Forms in Early 2027

1. Confirm your ALE status by calculating your 2026 monthly full time and full time equivalent headcount and averaging across all 12 months.
2. Gather coverage data for every full time employee, including which months coverage was offered, the employee's share of the lowest cost premium, and enrollment status.
3. Assign the correct indicator codes on Line 14 and Line 16 of Form 1095-C for each employee, each month. These codes determine whether you qualify for an affordability safe harbor.
4. Furnish 1095-C forms to employees no later than January 31, 2027.
5. File Form 1094-C and copies of all 1095-C forms with the IRS by February 28, 2027 if filing on paper, or March 31, 2027 if filing electronically (electronic filing is mandatory if you are filing 10 or more information returns in aggregate across all return types, which captures nearly every ALE).
6. Retain copies of all filings for at least four years in case of an IRS inquiry or audit.

If this list feels like a lot to manage alongside running your business, you are not alone. Many Miami-Dade County employers outsource this process entirely through managed accounting services that coordinate payroll data, benefits enrollment records, and IRS filing deadlines in one place.

The Real Cost of Getting ACA Reporting Wrong

The IRS penalty structure for ACA non-compliance has two tracks, and both can add up fast for a South Florida business with even a modest workforce.

Penalty A applies if you fail to offer minimum essential coverage to at least 95% of your full time employees and at least one employee receives a premium tax credit through the marketplace. For 2026, this penalty is calculated per full time employee (minus the first 30), and it adds up monthly.

Penalty B applies if you did offer coverage, but it was either unaffordable or did not provide minimum value, and an employee received a premium tax credit instead. This penalty is assessed only for the employees who went to the marketplace.

Here is what this looks like in dollar terms for three common South Florida business scenarios:

These figures illustrate why ACA compliance deserves the same attention as income tax compliance. A single overlooked part time staffing increase that pushes you over the 50 full time employees threshold can expose your business to six figure penalty risk if coverage offers and filings are not handled correctly.

Late Filing and Incorrect Filing Penalties

Separate from the Section 4980H employer shared responsibility penalties above, the IRS also assesses per form penalties for late or incorrect 1095-C and 1094-C filings, similar to penalties for other information returns like 1099s. These penalties apply per form and increase based on how late the correction is made, with higher caps for businesses with over $5 million in gross receipts. For a Miami-area employer filing 70 or more 1095-C forms, even a modest per form penalty multiplies quickly across your entire workforce.

Coordinating ACA Reporting With Your Overall Tax Strategy

ACA compliance should not exist in a silo separate from your broader tax planning. Employer shared responsibility penalties are not deductible as a business expense, which means every dollar of penalty exposure hits your bottom line at full value with no offsetting write off. This is one more reason South Florida business owners benefit from integrating ACA reporting into a year round business tax strategy rather than treating it as a once a year scramble in January.

Businesses using virtual CPA services throughout the year typically catch ALE threshold crossings months before the filing deadline, giving them time to correct coverage offers, document safe harbor eligibility, and avoid penalty exposure entirely. Pairing this with clean, consistent small business bookkeeping ensures your headcount and hours data is accurate when it comes time to run the full time equivalent calculation.

Frequently Asked Questions

Q: How do I know if my business is an applicable large employer for 2027 filing? A: Calculate your average monthly full time employee count plus full time equivalents from part time staff across all 12 months of 2026. If that average is 50 or more, you are an applicable large employer required to file Form 1095-C and Form 1094-C in early 2027. This calculation must include every month, not just your peak season, so seasonal South Florida businesses should review the full year carefully.

Q: What happens if I cross 50 employees for only a few months during the year? A: The IRS looks at your average across the full calendar year, so a short term seasonal spike does not automatically make you an applicable large employer. However, there is also a separate seasonal worker exception that excludes businesses from ALE status if they exceed 50 full time equivalent employees for 120 days or fewer in the prior year, using only seasonal workers to cross that threshold.

Q: Can I file Form 1095-C myself, or do I need a payroll provider? A: You can file these forms yourself if you have accurate coverage and enrollment data, but many South Florida business owners find the coding on Lines 14 and 16 confusing, since an incorrect code can trigger unnecessary IRS penalty notices. Working with a payroll provider or accounting firm that handles ACA reporting as part of ongoing compliance work significantly reduces the risk of coding errors.

Q: Does being headquartered in Florida change my ACA filing requirements? A: No, ACA reporting is a federal requirement under the Internal Revenue Code and applies the same way to a Coral Gables employer as it does to a business in any other state, since Florida has no state income tax reporting equivalent to layer on top. That said, South Florida's seasonal and hospitality heavy economy makes the full time equivalent calculation especially important to run carefully each year.

Q: What is the most common mistake small businesses make with ACA reporting? A: The most common mistake is failing to recalculate ALE status each year, assuming that because a business was under 50 employees last year, it still is this year after a hiring surge. The second most common mistake is miscoding the affordability safe harbor on Form 1095-C, which can trigger IRS penalty notices even when the employer actually offered compliant coverage.

Q: What if I receive an IRS penalty notice for ACA non-compliance I believe is wrong? A: The IRS typically issues Letter 226-J to propose employer shared responsibility penalties, and employers have a limited window, usually 30 days, to respond with documentation disputing the assessment. Responding promptly with accurate coverage records and correct Form 1095-C coding can significantly reduce or eliminate the proposed penalty, which is another reason to keep thorough records throughout the year.

Getting Ahead of Your 2027 ACA Filing Deadlines

Determining applicable large employer status is not a one time exercise. It is an annual calculation that every growing South Florida business, from Coral Gables professional firms to Miami-Dade County construction companies, needs to revisit every single year as headcount shifts. If your 2026 average full time employee count, combined with full time equivalents, reached 50 or more, you are required to furnish Form 1095-C to employees by January 31, 2027 and file Form 1094-C with the IRS by February 28 or March 31, 2027 depending on your filing method.

The penalties for missing these deadlines or filing incorrectly are not deductible and can reach six figures even for a mid-sized employer. Rather than facing that risk alone, our Coral Gables headquartered team at WAYG works with South Florida business owners year round to track ALE thresholds, coordinate coverage documentation, and file accurate, on time ACA forms.
