If you're an employer, you've probably asked this question. The short answer: no federal law requires every company to offer health benefits. But the real answer is more complicated—especially under the Affordable Care Act (ACA). For many businesses, offering health coverage goes from a perk to a legal requirement based on size and structure. Getting this right matters for compliance and for your team.
The ACA Employer Mandate
The centerpiece of mandatory healthcare benefits is the ACA's “employer shared responsibility” rule, better known as the employer mandate. It applies to Applicable Large Employers (ALEs)—companies with 50 or more full-time equivalent employees (FTEs) in the prior year. If you're an ALE, you must offer affordable, minimum-value coverage to full-time employees (those averaging 30+ hours a week) or risk IRS penalties.
What the ACA requires of ALEs
The coverage must meet two tests:
- Affordability: For 2024, the employee's share of the self-only premium can't exceed 8.39% of household income. Employers usually use one of three IRS safe harbors to check this.
- Minimum Value: The plan must cover at least 60% of total allowed costs, including substantial coverage for doctor visits and hospital stays.
- Reporting: ALEs file Forms 1094-C and 1095-C with the IRS each year and give copies to employees.
State rules add another layer
Several states have their own mandates—often with lower thresholds. California's applies to employers with just one employee. Massachusetts and New Jersey have similar laws. You need to check both federal and state rules.
What happens if you don't comply?
ALEs that fail to offer compliant coverage face two main penalties:
- Penalty A (no-offer penalty): If you don't offer coverage to at least 95% of full-time employees and one employee gets a premium tax credit through a Marketplace, you pay a penalty per full-time employee (minus the first 30).
- Penalty B (inadequate-offer penalty): If you offer coverage but it's unaffordable or doesn't meet minimum value, and an employee gets a credit, you pay per employee who gets the credit.
What if you're not subject to a mandate?
Smaller employers—under 50 FTEs—aren't required to offer health benefits. WellthCare offers a zero-net-cost way to add immediate value: employees earn store dollars and automatic retirement contributions for verified preventive care — with no new employer out-of-pocket cost. But it's still a smart move. Good benefits help you attract and keep talent, boost morale, and build a healthier, more productive workforce. Innovative options like WellthCare show where things are heading. By adding a zero-cost layer on top of existing plans, they give employees immediate value—like $0 copay preventive care and earned rewards—while gathering data to make smarter benefits choices. That data can even support a shift to self-funded models like WellthCare Complete™ when it makes sense.
Best practices for every employer
- Know your headcount. Track hours to determine FTE counts and full-time status under ACA rules.
- Document everything. Keep records of offers, plan details, and affordability calculations.
- Stay current. ACA rules and state laws change. Work with a broker, advisor, or attorney.
- Think of benefits as an investment. Even when optional, a strategy that emphasizes preventive care and financial wellness can cut long-term costs and give you a competitive edge.
So: healthcare benefits aren't universally mandatory. But for mid-size and large companies, the ACA effectively requires them. For everyone else, a thoughtful, compliant strategy isn't just about avoiding penalties—it's a direct investment in your people and your business's future.
