For many Colorado employers, ACA reporting can feel more complicated than it should be. Between determining Applicable Large Employer (ALE) status, understanding Forms 1094 and 1095, and keeping up with deadlines, it’s easy to miss something important.
This guide breaks it down clearly—what’s required, who it applies to, and where employers commonly run into issues.
What Is ACA Reporting for Employers?
ACA reporting refers to the annual requirement for certain employers to report information about the health coverage they offer (or don’t offer) to employees.
These filings help the IRS determine:
- Whether employers are meeting coverage requirements
- Whether employees may qualify for premium tax credits
- Whether employer shared responsibility penalties may apply
Who Is Required to File ACA Forms?
Not all employers are required to complete ACA reporting. The requirement generally applies to businesses that meet the definition of an Applicable Large Employer (ALE).
What Is an Applicable Large Employer (ALE)?
An Applicable Large Employer (ALE) is generally defined as a business with:
- 50 or more full-time employees, including full-time equivalent employees (FTEs)
- Measured over the prior calendar year
What counts as full-time?
- Employees working 30+ hours per week (or 130 hours per month)
If you are an ALE, you are typically required to:
- Offer affordable, minimum value coverage to eligible employees
- Complete ACA reporting annually
Employers below this threshold are generally not subject to these specific reporting requirements, though other compliance considerations may still apply.
What Forms Do Employers Need to File for ACA Compliance?
Applicable Large Employers are responsible for filing two primary forms: 1094-C and 1095-C
Form 1094-C is the summary transmittal submitted to the IRS, while Form 1095-C provides detailed, employee-level information about coverage.
Form 1095-C
Form 1095-C is provided to employees and includes:
- Whether coverage was offered
- The cost of the lowest-cost plan available
- Months of eligibility
1095-C = employee detail
Employees use this form for their personal tax records.
Form 1094-C
Form 1094-C includes:
- Total employee counts
- Confirmation of coverage offerings
- Aggregated group information, if applicable
1094-C = employer summary
When Are ACA Reporting Forms Due Each Year?
ACA reporting deadlines can shift slightly, but generally:
- January 31 – Provide Form 1095-C to employees (often extended to early March by IRS notice)
- February 28 – File paper forms with the IRS
- March 31 – File electronically with the IRS
Do ACA Forms Need to Be Filed Electronically?
Employers filing 10 or more forms are typically required to file electronically. Requirements can change, so it’s important to confirm filing thresholds each year.
How Do Employers Determine ALE Status?
ALE status is based on your average workforce size from the previous calendar year, including:
- Full-time employees
- Full-time equivalent employees (calculated based on part-time hours)
Because this calculation can be nuanced—especially for employers with variable-hour or seasonal employees—it’s important to review complete payroll data before making a determination.
What Are Common ACA Reporting Mistakes Employers Make?
Even well-run organizations can run into ACA reporting issues. Here are a few we see most often:
1. Misclassifying ALE Status
Underestimating part-time or seasonal hours can lead to incorrect classification.
2. Inaccurate Employee Data
Errors in Social Security numbers, employment dates, or coverage details can trigger IRS notices.
3. Missing Affordability Calculations
Coverage must meet affordability standards using IRS-approved safe harbor methods.
4. Late or Incorrect Filings
Missing deadlines or submitting incomplete forms can result in penalties—even if coverage was offered.
What Happens If Employers Make ACA Reporting Mistakes?
The IRS may assess penalties for:
- Failure to file required forms
- Failure to furnish forms to employees
- Filing incomplete or inaccurate information
Penalty amounts can change annually and are often assessed per form, which can add up quickly depending on employer size.
In some cases, employers may be able to correct errors or qualify for limited relief, but this is not guaranteed.
How Can Employers Avoid ACA Reporting Penalties?
A proactive approach can help reduce risk. Consider:
- Reviewing ALE status annually
- Validating employee and coverage data early
- Coordinating between payroll, HR, and benefits platforms
- Building a timeline well ahead of filing deadlines
ACA reporting is not just a year-end task—it’s tied to decisions made throughout the year.
What Do Colorado Employers Need to Know About ACA Reporting?
While ACA reporting is governed at the federal level, Colorado employers—especially those experiencing growth—should pay close attention to:
- Workforce changes that may impact ALE status
- Benefits eligibility tracking
- Alignment between benefits strategy and compliance requirements
As your organization grows, ACA obligations can change quickly.
