Employer Mandate
The Employer Mandate under the Affordable Care Act (ACA) requires larger employers (generally those with 50 or more full-time equivalent employees, or FTEs) to provide health insurance to their full-time employees and dependents. For small businesses, this mandate generally does not apply unless they are under common ownership that collectively meets the 50 FTE threshold.
