This is the “Affordable Care Act (ACA) Compliance” section of the Employee Benefits FAQ Library.
The Affordable Care Act (ACA) employer mandate requires certain employers to offer health insurance coverage to their full-time employees. Employers that meet the definition of an Applicable Large Employer (ALE)—generally those with 50 or more full-time equivalent employees—must offer health coverage that meets affordability and minimum value standards.
If an ALE fails to offer coverage to enough employees or offers coverage that does not meet ACA requirements, the employer may face potential IRS penalties if employees receive premium tax credits through the public health insurance marketplace.
Under the ACA, a full-time employee is generally defined as someone who works at least 30 hours per week or 130 hours per month.
Employers must track employee hours to determine which employees qualify as full-time for purposes of health insurance eligibility. These rules help determine whether an employer must offer coverage and whether they are considered an Applicable Large Employer.
The ACA requires employer-sponsored health insurance to meet affordability standards. Coverage is considered affordable if the employee’s required contribution for the lowest-cost self-only plan does not exceed a percentage of their income determined annually by the IRS.
Because employers typically do not know an employee’s household income, the IRS provides several affordability safe harbor methods employers can use to determine compliance.
Minimum value refers to the level of coverage provided by a health insurance plan. A plan meets the ACA’s minimum value requirement if it covers at least 60% of the total allowed cost of covered healthcare services.
This means the plan pays at least 60% of healthcare costs on average, while employees pay the remaining portion through deductibles, copays, and coinsurance.
Plans that fail to meet minimum value may not satisfy ACA employer mandate requirements.
Applicable Large Employers must report health coverage information to the IRS each year using:
These forms help the IRS determine whether employers are complying with ACA requirements and whether employees are eligible for marketplace subsidies.
Employers that are considered Applicable Large Employers may face Employer Shared Responsibility penalties if they fail to meet ACA requirements.
Penalties may apply if:
Penalties are assessed by the IRS when an employee receives premium tax credits through the health insurance marketplace.
A full-time equivalent employee calculation combines hours worked by both full-time and part-time employees to determine whether an employer qualifies as an Applicable Large Employer under the ACA.
For example, multiple part-time employees working fewer hours may collectively equal one full-time equivalent employee for purposes of determining ACA applicability.
This calculation helps determine whether an employer meets the 50 employee threshold for ACA requirements.
The IRS provides several safe harbor methods that allow employers to determine whether their health coverage meets ACA affordability standards without knowing employees’ household income.
Common safe harbor methods include:
Employers typically work with benefits advisors or payroll specialists to apply the appropriate method.
Seasonal employees may be counted differently depending on the employer’s workforce structure and how long employees work during the year.
In some cases, employers may qualify for a seasonal worker exception when determining Applicable Large Employer status if the workforce exceeds 50 employees for only a limited number of days during the year.
Employers should carefully review ACA measurement rules to determine how seasonal employees are classified.
ACA employer penalties are sometimes referred to as Employer Shared Responsibility Payments. These penalties may apply if an Applicable Large Employer fails to offer compliant coverage.
Two types of penalties may apply:
Penalties are typically triggered when at least one employee receives a subsidy through the health insurance marketplace.
