The HR Manager’s Guide to ACA Measurement Methods

As an HR manager, understanding the complexities of ACA compliance is crucial to ensuring that your company remains compliant with the regulations set forth by the Affordable Care Act (ACA). ACA compliance involves many moving parts, especially when it comes to tracking employee hours, determining full-time status, and submitting the correct forms to the IRS. In this guide, we’ll explore the ACA measurement methods that HR professionals need to understand to avoid penalties and stay ahead of compliance requirements.

What is ACA Compliance?

The Affordable Care Act (ACA) requires Applicable Large Employers (ALEs) to offer health coverage to their full-time employees and report that coverage to the IRS. The purpose of the ACA is to make sure that more people have access to affordable health insurance. For HR managers, this means understanding how to track employee hours, monitor eligibility, and report compliance data correctly.

What Does ACA-Track Do?

To simplify ACA compliance tracking, tools like ACA-Track provide businesses with a powerful solution to handle the nuances of ACA regulations. ACA-Track helps employers collect, monitor, and report employee hours worked, employee eligibility for benefits, and ensure accurate filing with the IRS.

Key features of ACA-Track include:

  • ACA 1095 C Monthly Line Code Audits: ACA-Track audits each month’s employee hours and ensures correct reporting codes.

  • Variable Hour Tracking of Employees: The tool keeps track of part-time, full-time, and variable-hour employees, ensuring all employees are correctly classified.

  • Federal and State Reporting: ACA-Track handles the generation of 1094-C and 1095-C forms for both federal and state reporting requirements.

  • Filing with the IRS: It also ensures that ACA filings are submitted to the IRS electronically via XML file.

With ACA-Track, employers can ensure that they remain compliant and reduce the risk of errors, penalties, and other complications related to ACA reporting.

Understanding ACA Measurement Methods

The ACA uses specific measurement methods to determine which employees are considered full-time and therefore eligible for health coverage under the ACA. The measurement methods focus primarily on hours worked and employee status, as they are key to determining whether an employee qualifies for benefits.

Here’s a breakdown of the main measurement methods:

1. Monthly Measurement Method

This method tracks employee hours on a monthly basis. An employee is considered full-time if they work an average of at least 30 hours per week, or 130 hours per month. If they meet this threshold in a given month, they are eligible for health coverage in the following months, under the ACA.

  • Advantages: Simpler to implement since it only requires tracking hours on a month-by-month basis.

  • Disadvantages: It may not provide the flexibility needed for employees whose hours vary significantly from month to month.

2. Look-Back Measurement Method

The Look-Back Measurement Method is used to determine full-time status based on a “measurement period,” which is typically 3 to 12 months. During this period, employers track the number of hours worked by each employee. If an employee averages 30 hours per week (or 130 hours per month) during the measurement period, they are considered full-time and must be offered coverage during the following “stability period.”

  • Advantages: Provides more flexibility for employees with variable hours and seasonal work.

  • Disadvantages: It requires more extensive tracking and can be more complex to manage, especially for employers with large numbers of part-time or variable-hour workers.

3. Administrative Period

The Administrative Period is the period between the Measurement Period and the Stability Period. During this time, the employer reviews the data collected during the Measurement Period and makes decisions regarding employee eligibility for health coverage.

  • Purpose: This period ensures that the employer has time to assess employee status and make any necessary adjustments to coverage.

4. Stability Period

The Stability Period is a set time period (usually 6 to 12 months) during which an employee’s health coverage status is determined. If an employee was classified as full-time during the Measurement Period, they will be offered coverage during the Stability Period, regardless of the number of hours worked during that period.

The Importance of Tracking Hours for Part-Time and Variable Hour Employees

For employers, accurately tracking the hours worked by part-time and variable-hour employees is essential for ACA compliance. Here’s why:

  • Eligibility Determination: The key to determining whether an employee is full-time is their average weekly or monthly hours. Without tracking these hours accurately, you cannot determine whether the employee is eligible for health coverage under ACA regulations.

  • Avoiding Penalties: If your company does not track part-time or variable-hour employee hours and an employee qualifies for health coverage through the Health Insurance Marketplace, you could be liable for penalties.

How ACA-Track Simplifies the Process

ACA-Track’s comprehensive tracking solution helps ensure that your company stays on top of variable-hour employees, providing detailed data on hours worked for all employees—whether part-time, full-time, or seasonal. With its user-friendly interface, ACA-Track allows HR managers to:

  • Track employee hours worked from multiple systems (including timekeeping, payroll, and employee mobile entries)

  • Monitor employee eligibility thresholds and receive alerts when employees exceed the thresholds for health coverage

  • Maintain all ACA compliance data in one centralized, easily accessible location

By integrating with payroll systems and HRIS, ACA-Track makes the ACA tracking process seamless, allowing HR managers to focus on other important tasks while ensuring compliance.

The Role of HR in ACA Compliance

While the ACA mandates health coverage for full-time employees, HR is responsible for tracking employee hours, monitoring eligibility, and ensuring that employees receive proper health insurance offers. This means HR professionals must:

  • Stay up to date on ACA regulations

  • Monitor employee eligibility and make adjustments when necessary

  • Ensure accurate ACA reporting to the IRS

  • Manage complex reporting requirements for variable-hour employees

In large organizations, multiple departments (HR, benefits, payroll, and finance) often collaborate to ensure that ACA compliance is met. It’s common for HR or the Benefits Director to oversee the ACA compliance process.

Using a third-party provider like ACA-Track offers several benefits:
