As an employer planning for the year ahead, ACA reporting compliance remains an important—and often underestimated—risk area. While many organizations believe that simply offering health insurance is enough, the reality is that how ACA data is tracked and reported is what the IRS ultimately evaluates.
In practice, many employers that face ACA penalties are offering coverage—but still getting tripped up by reporting errors.
Who Is Required to File ACA Forms—and Why It Matters
If your organization averages 50 or more full-time and full-time equivalent (FTE) employees, you are considered an Applicable Large Employer (ALE) under the Affordable Care Act.
ALEs must file:
- Form 1095-C for each full-time employee, detailing offers of coverage
- Form 1094-C, filed with the IRS as the employer’s annual ACA compliance summary
These forms allow the IRS to determine whether:
- Coverage was properly offered
- Coverage met affordability and minimum value standards
- Employees were eligible for premium tax credits
Key point for employers: ACA penalties are frequently triggered by reporting inconsistencies, as well as lack of benefits.
ACA Reporting Deadlines Employers Cannot Miss
ACA reporting follows firm annual deadlines:
- January 31 – Forms 1095-C provided to employees
- February 28 – Paper filing deadline with the IRS (if applicable)
- March 31 – Electronic filing deadline with the IRS (most employers)
Missing a deadline or filing incorrect information can immediately expose employers to penalties—even before the IRS reviews affordability or eligibility.
Real-World ACA Penalty Examples Employers Encounter
Understanding how penalties actually occur helps put the risk into perspective.
Example 1: Incorrect Coding Triggers a Six-Figure Assessment
An employer with approximately 150 employees offered health coverage, but several Forms 1095-C were coded incorrectly on Line 14 and Line 16. The IRS interpreted this as a failure to offer affordable coverage for multiple months.
Result:
The employer received IRS Letter 226J proposing penalties exceeding $180,000, requiring months of back-and-forth documentation to resolve.
Example 2: Variable-Hour Employees Misclassified
A growing company relied on manual tracking for variable-hour employees. Several employees crossed full-time thresholds but were not flagged correctly for coverage offers.
Result:
The IRS assessed penalties under the employer shared responsibility provisions for each affected month, resulting in tens of thousands of dollars in proposed penalties—despite coverage being offered later.
Example 3: Late and Incomplete Filings
An employer filed ACA forms after the deadline and failed to include corrected forms once errors were identified.
Result:
The employer faced per-form penalties for late and inaccurate filings, which can accumulate quickly—especially for organizations with large employee populations.
Example 4: Data Mismatch Between Payroll and Benefits
Payroll records did not align with benefits enrollment data, causing discrepancies in reported full-time status.
Result:
The IRS issued a compliance notice requesting substantiation. The employer spent significant internal time reconstructing records and defending reporting positions.
Why These Issues Are So Common
ACA reporting requires:
- Month-by-month employee tracking
- Accurate affordability calculations
- Consistent data across payroll, HR, and benefits systems
- Correct IRS coding on every form
Without centralized oversight, even well-intentioned employers can unknowingly expose themselves to penalty risk.
How Employers Reduce ACA Reporting Risk with PES
Rather than reacting to IRS notices, many employers choose a proactive approach by partnering with PES.
How PES Helps:
- Continuous tracking of employee hours and ACA eligibility
- Accurate preparation and delivery of Forms 1095-C
- Timely filing of Form 1094-C with the IRS
- Validation of affordability safe harbors and required codes
- Alignment of payroll, benefits, and HR data
- Support responding to IRS letters and audits, if issued
This approach helps employers move from reactive compliance to defensible, audit-ready reporting.
Start the Year Ahead, Not Behind
ACA reporting is not a once-a-year task—it’s an ongoing compliance responsibility. As the new year begins, employers who review their ACA processes early are better positioned to avoid penalties, reduce administrative strain, and protect their business. The cost of prevention is far lower than the cost of correction.
