What the ACA employer mandate requires
The Affordable Care Act employer mandate, also called the "employer shared responsibility provision," requires employers with 50 or more full-time equivalent employees to:
1. Offer health insurance to at least 95% of full-time employees and their dependent children
2. Make it affordable — employee premium costs cannot exceed 9.12% of household income (2026 rate)
3. Provide minimum value — the plan must cover at least 60% of covered healthcare costs
4. Pay penalties if they don't comply — up to $4,460 per employee annually
According to Kaiser Family Foundation data, 96% of eligible employers now offer health insurance, up from 92% before the mandate.

Most employer plans exceed this minimum — the average employer plan has 80% actuarial value.
What you should do
1. Check if your employer is subject to the mandate — ask HR how many full-time equivalent employees the company has
2. Verify affordability — calculate whether your premium exceeds 9.12% of household income
3. Understand your coverage — ensure the plan meets minimum value requirements
4. Know your alternatives — if employer coverage is unaffordable, you may qualify for marketplace subsidies
