Section 4980H(a) Penalty

If you’re a growing business owner, you may have heard about the Section 4980H(a) Penalty and wondered, “Does this apply to me?” You’re not alone. The Affordable Care Act (ACA) introduced employer shared responsibility rules that can feel overwhelming, especially if you don’t have a full HR or legal team on staff.
As a small business owner or HR manager, the last thing you want is an unexpected IRS letter assessing penalties you didn’t even know existed. And as an employee, you want to know your employer is offering compliant health coverage that protects you and your family.
Let’s break this down in plain English—what the Section 4980H(a) Penalty is, who it applies to, how it’s calculated, and what you can do to avoid it.
What Is the Section 4980H(a) Penalty?
The Section 4980H(a) Penalty is part of the ACA’s Employer Shared Responsibility provisions under Internal Revenue Code Section 4980H. It’s often called the “A Penalty” or the “No Offer Penalty.”
In simple terms, it applies when:
• An Applicable Large Employer (ALE) fails to offer minimum essential coverage (MEC) to at least 95% of its full-time employees (and their dependents), and
• At least one full-time employee receives a premium tax credit through the Health Insurance Marketplace.
This rule is enforced by the IRS. You can review the statutory framework directly on IRS.gov under Employer Shared Responsibility Provisions.
Who Is an Applicable Large Employer (ALE)?
An ALE is a business that averages 50 or more full-time employees (including full-time equivalent employees) during the prior calendar year.
Here’s the nuance:
• A full-time employee is someone working 30 or more hours per week on average.
• Part-time hours are combined to calculate “full-time equivalents.”
So even if you don’t have 50 full-time employees on payroll, you could still cross the threshold once part-time hours are factored in.
If you’re under 50 full-time equivalents, the Section 4980H(a) Penalty does not apply to you. That’s a big relief for many small businesses.
How the Section 4980H(a) Penalty Is Calculated
This is where things get serious.
If an ALE fails to offer coverage to at least 95% of full-time employees and just one employee qualifies for a premium tax credit, the penalty is triggered for the entire full-time workforce—minus the first 30 employees.
For 2026 (penalty amounts are indexed annually), the A Penalty is calculated roughly as:
Total full-time employees – 30
Multiplied by the annual penalty amount (adjusted each year by the IRS)
The IRS publishes updated penalty amounts annually in its Revenue Procedures.
Let’s look at a simplified example:
• You have 80 full-time employees.
• You offer no health coverage.
• One employee enrolls in Marketplace coverage and receives a premium tax credit.
Your penalty would be:
(80 – 30) × annual penalty amount
That’s 50 employees subject to the penalty. Multiply that by the IRS annual rate, and you’re suddenly looking at a six-figure liability.
That’s not pocket change for a growing company.
How Is This Different from the 4980H(b) Penalty?
There are actually two types of ACA employer penalties:
• Section 4980H(a) Penalty – Failure to offer coverage to at least 95% of full-time employees.
• Section 4980H(b) Penalty – Coverage was offered, but it was either unaffordable or did not provide minimum value.
The A Penalty is generally much larger because it applies to all full-time employees (minus 30), not just the ones receiving tax credits.
Think of it this way:
If you don’t offer coverage at all (or to enough people), the IRS applies a broad penalty.
If you offer coverage but it doesn’t meet standards, the penalty is narrower.
Why Small and Growing Businesses Should Pay Attention
You might be thinking, “We’re only at 42 employees—we’re fine.” Maybe. But what about next year?
Rapid Growth Can Trigger ALE Status
Startups and expanding businesses often cross the 50-employee threshold faster than expected. Once you’re an ALE, you must comply the following calendar year.
That means:
• Tracking hours carefully
• Identifying full-time status correctly
• Offering compliant coverage on time
Miss those steps, and the Section 4980H(a) Penalty becomes a real risk.
Controlled Group Rules Add Complexity
The IRS applies aggregation rules for related entities under common ownership. If you own multiple businesses, you may need to combine employee counts to determine ALE status.
This is outlined under Internal Revenue Code Sections 414(b), (c), and (m). Many business owners are surprised by this. Structuring your companies separately doesn’t automatically shield you from ACA counting rules.
What Counts as an Offer of Minimum Essential Coverage?
To avoid the A Penalty, you must offer Minimum Essential Coverage (MEC) to at least 95% of full-time employees and their dependent children (up to age 26).
MEC generally includes:
• Most employer-sponsored group health plans
• Individual major medical insurance policies
• Certain government programs
The Department of Health and Human Services (HHS) and IRS define MEC standards under the ACA.
Importantly, simply giving employees a stipend without structure does not count as offering MEC. Unstructured taxable reimbursements typically won’t protect you from penalties.
That’s where compliant reimbursement arrangements—like ICHRA—come into play.
How ICHRA Can Help Avoid the Section 4980H(a) Penalty
Add: 'ICHRA is subject to ERISA and PHSA requirements and is treated as a group health plan; employers must provide required notices and maintain plan documentation. See 26 CFR §54.9815-2711(d) and 84 Fed. Reg. 28888 (June 20, 2019).'
For ALEs, an ICHRA can:
• Qualify as an offer of MEC
• Be designed to meet affordability standards
• Satisfy employer mandate requirements
When structured properly, offering an affordable ICHRA to at least 95% of full-time employees can protect your business from the Section 4980H(a) Penalty.
Affordability Still Matters
Even if you avoid the A Penalty, you must ensure the ICHRA allowance is “affordable” under IRS guidelines to avoid the 4980H(b) Penalty.
Affordability is based on:
• The lowest-cost silver plan available to the employee
• The employee’s household income (using permitted safe harbors such as W-2 wages, rate of pay, or federal poverty level)
The IRS publishes affordability thresholds annually.
This is where compliance gets technical—and where software support becomes invaluable.
From an Employee Perspective: Why This Matters
Employees may not use the term Section 4980H(a) Penalty in everyday conversation, but they feel its effects.
If an employer fails to offer compliant coverage:
• Employees may rely solely on the Marketplace
• They may face uncertainty about premium tax credits
• They may lose access to employer-sponsored tax advantages
On the flip side, when employers proactively comply:
• Employees gain structured, tax-advantaged health benefits
• Families have more stability
• There’s less confusion during tax season
Compliance isn’t just about avoiding penalties—it’s about building trust.
Common Mistakes That Trigger Penalties
Over the years, I’ve seen a few patterns trip employers up:
- Miscounting full-time employees
- Failing to track variable-hour staff properly
- Offering coverage too late in the year
- Assuming a taxable stipend counts as compliant coverage
- Ignoring IRS Letter 226-J (the penalty assessment letter)
Once you receive an IRS notice, you have limited time to respond. Documentation and reporting (Forms 1094-C and 1095-C) become critical.
Final Thoughts on Section 4980H(a) Penalty Compliance
The Section 4980H(a) Penalty can be financially devastating for Applicable Large Employers that fail to offer compliant health coverage—but with proper planning, it’s entirely avoidable. By accurately determining ALE status, offering Minimum Essential Coverage (including a properly structured ICHRA), and meeting affordability standards, small and growing businesses can stay on the right side of the ACA while giving employees meaningful health benefits. At SimplyHRA, we help business owners and HR managers design compliant ICHRA plans, automate affordability calculations, streamline reporting, and reduce ACA penalty risk—all without enterprise-level complexity.

IRS Enforcement and What Happens After a Violation
If the Section 4980H(a) Penalty is triggered, it doesn’t happen quietly. The IRS enforces employer shared responsibility penalties through a structured notice process, primarily using Letter 226-J.
Understanding IRS Letter 226-J
Letter 226-J is the IRS’s proposed penalty notice. It typically includes:
• The penalty calculation
• A list of employees who received premium tax credits
• Form 14764 (ESRP Response Form)
• Form 14765 (Employee Premium Tax Credit Listing)
In plain terms, the IRS is saying, “We believe you owe a penalty—here’s why.”
Employers usually have 30 days to respond. That window matters. Failing to respond can result in automatic assessment and further collection action.
You Can Disagree—But You Need Documentation
Sometimes the IRS gets it wrong. Maybe:
• You did offer coverage to 95% of full-time employees
• An employee was misclassified
• An employee shouldn’t have received a premium tax credit
To dispute the Section 4980H(a) Penalty, you’ll need:
• Accurate payroll records
• Documentation of coverage offers
• Signed waivers or declination forms
• Proof of affordability calculations
The burden of proof falls on the employer. That’s why recordkeeping isn’t just administrative busywork—it’s your defense strategy.
Reporting Obligations That Tie Directly to the Penalty
Avoiding the Section 4980H(a) Penalty isn’t just about offering coverage. It’s also about reporting it correctly.
Applicable Large Employers must file:
• Form 1094-C (Transmittal of Employer-Provided Health Insurance Offer and Coverage Information Returns)
• Form 1095-C (Employee statements)
These forms report:
• Whether coverage was offered
• To whom it was offered
• For which months
• The employee’s required contribution
The IRS cross-checks this information with Marketplace subsidy data. If an employee receives a premium tax credit and your 1095-C indicates no offer of coverage, that’s when the red flag goes up.
The instructions for these forms are published annually on IRS.gov and are updated frequently. Even minor coding errors can lead to notices.
Variable-Hour and Seasonal Employees—A Hidden Risk Area
One of the most misunderstood aspects of ACA compliance involves variable-hour employees.
The Look-Back Measurement Method
The ACA allows employers to determine full-time status using:
• The monthly measurement method, or
• The look-back measurement method
The look-back method lets employers measure hours over a defined period (typically 3–12 months) to determine eligibility for a future stability period.
If this system isn’t applied consistently, you could:
• Accidentally fail to offer coverage to someone who qualifies as full-time
• Drop below the 95% threshold
• Trigger the Section 4980H(a) Penalty
Restaurants, retail businesses, healthcare providers, and staffing agencies often face this complexity due to fluctuating schedules.
Waiting Period Limitations
Under ACA rules, waiting periods cannot exceed 90 calendar days (as enforced by the Department of Labor and HHS).
If you delay coverage improperly, even unintentionally, those uncovered months could count toward penalty exposure.
Timing matters more than most employers realize.
Mergers, Acquisitions, and Mid-Year ALE Status
Business transitions create another layer of risk.
What If You Cross 50 Employees Mid-Year?
ALE status is determined based on the prior calendar year’s average employee count. If you exceed 50 full-time equivalents this year, you’ll generally become an ALE next year.
That gives you a runway—but not much of one.
If you wait until December to think about it, you may not have enough time to:
• Design compliant coverage
• Establish employee classes
• Conduct affordability modeling
• Prepare payroll and reporting systems
Acquiring Another Company
In mergers and acquisitions, ACA controlled group rules can immediately affect ALE determination.
For example:
• If your 40-employee company acquires a 20-employee business, aggregation rules may apply.
• You could instantly meet ALE thresholds.
The IRS controlled group rules under Section 414 are complex and often require legal or tax review. Ignoring them can lead to surprise exposure under Section 4980H(a).
Budgeting for Compliance vs. Budgeting for Penalties
Let’s talk dollars and cents.
Paying the Section 4980H(a) Penalty is not a strategic alternative to offering coverage. Why?
• The penalty is not tax-deductible.
• It provides no benefit to employees.
• It increases reputational and retention risks.
By contrast, employer contributions toward health benefits are generally tax-deductible business expenses.
When business owners run the math, they often realize:
Investing in a structured, compliant health benefit strategy usually costs less long term than absorbing unpredictable penalties.
Employee Communication and Marketplace Coordination
Communication plays a bigger role than most employers expect.
When Employees Apply for Marketplace Coverage
When employees enroll in Marketplace plans and apply for premium tax credits, they must indicate whether their employer offered coverage.
If communication is unclear, employees may:
• Incorrectly report that no coverage was offered
• Trigger a Marketplace eligibility review
• Set off the IRS penalty process
Providing clear, written notices—especially with ICHRA plans—is essential.
If the ICHRA is unaffordable, the employee may decline it and claim PTCs. The notice must clearly explain this consequence.'
Clarity prevents confusion. Confusion prevents penalties.
State-Level Considerations
While the Section 4980H(a) Penalty is federal, certain states—like California, Massachusetts, New Jersey, Rhode Island, and the District of Columbia—have individual mandates.
This can indirectly affect employers because:
• Employees may face state penalties if uninsured
• Marketplace activity increases
• State exchanges coordinate with federal reporting
Employers operating in multiple states should ensure their coverage strategy works across jurisdictions.
Strategic Planning for the Next 3–5 Years
Compliance shouldn’t be reactive. It should be planned.
If you’re hovering near 50 employees or already classified as an ALE, consider:
• Projected headcount growth
• Wage increases affecting affordability calculations
• Remote workforce expansion across rating areas
• The long-term cost trend of traditional group insurance
Many employers shift toward ICHRA models because:
• They provide cost control by employee class
• They reduce exposure to annual group premium spikes
• They allow employees to choose coverage tailored to their geography
When structured correctly, this approach can satisfy ACA employer mandate requirements while offering flexibility that traditional group plans simply don’t.
Why Proactive Compliance Beats Reactive Damage Control
Once the IRS initiates penalty proceedings, you’re in defense mode. That means:
• Gathering months—or years—of payroll data
• Reviewing Marketplace subsidy eligibility
• Engaging accountants or legal counsel
• Managing internal stress and distraction
On the other hand, proactive compliance means:
• Clear eligibility tracking
• Automated affordability testing
• Documented offers of coverage
• Organized reporting
It’s a whole different experience.
The Bigger Picture for Employers and Employees
The Section 4980H(a) Penalty isn’t just a regulatory hurdle—it reflects a broader policy goal under the ACA: ensuring large employers contribute to the health coverage system.
For employers, that means accountability.
For employees, that means access.
For HR managers, that means building systems that work quietly in the background without constant fire drills.
When done right, compliance fades into routine operations. When ignored, it becomes a financial and operational crisis.

Frequently Asked Questions (FAQs) about Section 4980H(a) Penalty:
Q: Does the Section 4980H(a) Penalty apply if we offer coverage to 94% of full-time employees?
A: Unfortunately, no. The ACA requires Applicable Large Employers (ALEs) to offer minimum essential coverage to at least 95% of full-time employees and their dependent children. Falling even slightly below that threshold—94%, for example—can trigger the Section 4980H(a) Penalty if at least one full-time employee receives a premium tax credit through the Marketplace. That 5% margin is often referred to as the “error cushion,” but it’s not flexible beyond the statutory limit.
Q: Are spouses required to be offered coverage to avoid the Section 4980H(a) Penalty?
A: No. The employer mandate requires coverage to be offered to full-time employees and their dependent children up to age 26. Spousal coverage is not required under Section 4980H(a). However, many employers still choose to offer it for competitiveness and employee satisfaction.
Q: Can a company reduce hours to avoid triggering the Section 4980H(a) Penalty?
A: Employers can structure their workforce as they see fit, but intentionally manipulating hours solely to avoid offering coverage can create employee morale issues and potential legal risks. Also, the ACA defines full-time status as averaging 30 hours per week. If employees consistently meet that threshold, reducing hours may not be practical or sustainable. Strategic workforce planning is far more effective than reactive hour-cutting.
Q: Does the Section 4980H(a) Penalty apply to nonprofit organizations?
A: Yes. Tax-exempt organizations can still be Applicable Large Employers if they meet the 50 full-time equivalent threshold. The employer shared responsibility provisions apply regardless of tax status. Nonprofits are not exempt from ACA employer mandate rules.
Q: How does the IRS know whether an employee received a premium tax credit?
A: The Health Insurance Marketplace reports premium tax credit information to the IRS. The IRS then cross-references this data with employer filings (Forms 1094-C and 1095-C). If an employee receives a tax credit for a month in which the employer did not report an offer of coverage, the system flags the employer for potential penalty assessment.
Q: Can short-term limited duration insurance count as an offer to avoid the Section 4980H(a) Penalty?
A: No. Short-term limited duration plans generally do not qualify as minimum essential coverage under the ACA. Add footnote or clarification: 'Cafeteria plan salary reductions under IRC §125 cannot be applied to pay individual health insurance premiums purchased through the Health Insurance Marketplace (on-Exchange coverage). Off-Exchange purchases only.' Employers must ensure the coverage offered meets federal standards.
Q: If we mistakenly fail to offer coverage for one month, can that trigger the Section 4980H(a) Penalty for the entire year?
A: The penalty is calculated on a monthly basis. If the employer fails to meet the 95% threshold for a specific month and at least one full-time employee receives a premium tax credit for that same month, the penalty may apply for that month. However, repeated monthly failures can add up quickly over a calendar year.
Q: Do leased employees from a staffing agency count toward ALE status?
A: Potentially, yes. If workers are considered common law employees of your company, they may count toward your full-time employee calculation—even if they are paid through a staffing firm. The determination depends on who has direction and control over the workers. Misclassification in this area can significantly impact ALE status and exposure to the Section 4980H(a) Penalty.
Q: What happens if our employee declines our offer of coverage and still receives a premium tax credit?
A: If you offered affordable minimum essential coverage to at least 95% of full-time employees and properly documented that offer, the Section 4980H(a) Penalty should not apply—even if an employee declines coverage and improperly receives a tax credit. In those cases, the issue is typically resolved through IRS correspondence and documentation review.
Q: Is there a statute of limitations for the IRS to assess the Section 4980H(a) Penalty?
A: Yes, but it depends on proper filing. Generally, the IRS has three years from the date a complete and accurate Form 1094-C is filed to assess penalties. If required forms were not filed at all, the statute of limitations may remain open. Timely and accurate reporting is critical to closing that window.
Q: Can we retroactively fix a failure to offer coverage to avoid the penalty?
A: In most cases, coverage must be offered prospectively and within required timeframes. Retroactively offering coverage after an employee has already received a premium tax credit usually does not eliminate exposure for past months. That said, responding promptly to IRS notices and correcting reporting errors can mitigate financial impact.
Q: Does union-represented labor affect Section 4980H(a) compliance?
A: Collective bargaining agreements can influence how health benefits are structured, but they do not eliminate ACA employer mandate obligations. If the employees are considered your full-time employees under ACA definitions, you must still ensure coverage is offered in compliance with Section 4980H(a), even if benefits are negotiated through a union contract.
Q: Does the Section 4980H(a) Penalty apply to government employers?
A: Yes. Federal, state, and local government entities that meet the Applicable Large Employer threshold are subject to the employer shared responsibility provisions. Government employers must comply with the same 95% offer requirement and reporting obligations as private-sector ALEs.
Q: How are full-time equivalents (FTEs) calculated for determining ALE status?
A: To calculate FTEs, you total all hours worked by part-time employees in a month (capped at 120 hours per employee), then divide that total by 120. The result equals the number of full-time equivalent employees for that month. You then average those totals across the calendar year. This calculation determines ALE status only—it does not convert part-time employees into full-time employees for purposes of offering coverage.
Q: If we offer coverage for only part of the year, does that reduce the Section 4980H(a) Penalty?
A: The penalty is assessed monthly. If you failed to offer coverage for certain months but complied in others, the penalty would generally apply only for the non-compliant months—assuming at least one full-time employee received a premium tax credit during those months. Partial-year compliance can significantly reduce total exposure compared to year-long noncompliance.
Q: Are bonuses and commissions included when determining affordability related to Section 4980H(a)?
A: Affordability safe harbors such as the W-2 wages safe harbor typically use Box 1 W-2 wages, which include taxable wages and certain compensation elements like bonuses. However, affordability primarily affects exposure to the Section 4980H(b) Penalty rather than the Section 4980H(a) Penalty. Still, accurate wage tracking supports overall ACA compliance.
Q: Does offering coverage to 95% of full-time employees guarantee we won’t owe any penalty?
A: Not necessarily. Meeting the 95% threshold helps you avoid the Section 4980H(a) Penalty. However, if the coverage offered is unaffordable or does not provide minimum value, you may still face the Section 4980H(b) Penalty for specific employees who receive premium tax credits. The two penalties operate independently.
Q: What role does COBRA coverage play in avoiding the Section 4980H(a) Penalty?
A: Offering COBRA to former employees does not satisfy the requirement to offer coverage to current full-time employees. However, COBRA may be relevant in limited circumstances, such as when an employee’s hours are reduced. Proper administration of COBRA helps maintain compliance but does not replace the need to meet the 95% offer rule for active full-time employees.
Q: If an employee terminates mid-month, are we still required to offer coverage for that month?
A: Generally, if the employee was full-time and employed on the first day of the month, an offer of coverage for that month is expected. Coverage rules can vary depending on plan terms and measurement methods, but careful tracking of hire and termination dates is essential for accurate monthly reporting.
Q: Can penalties be waived due to reasonable cause?
A: The IRS may consider penalty relief in limited situations involving reasonable cause, but this is not automatic and requires substantial documentation. Employers must demonstrate that they exercised ordinary business care and prudence but were unable to comply. Relying on penalty relief as a strategy is risky; proactive compliance is far more reliable.
Q: How does remote work affect Section 4980H(a) compliance?
A: Remote work can complicate affordability calculations because employees may reside in different rating areas with varying premium costs. While the Section 4980H(a) Penalty focuses on the offer threshold, remote workforce distribution can affect whether your health benefit strategy remains compliant across states and local markets.
Q: If we mistakenly classify someone as an independent contractor, could that impact Section 4980H(a)?
A: Yes. If the IRS later determines that a worker classified as an independent contractor should have been treated as a common law employee, that individual may count toward your full-time employee total. Misclassification could affect ALE status, the 95% offer calculation, and overall penalty exposure.
Q: Are new businesses immediately subject to the Section 4980H(a) Penalty?
A: New businesses determine ALE status based on their expected average workforce size. If a new employer reasonably expects to employ 50 or more full-time employees (including equivalents) during the current calendar year, it may be treated as an ALE immediately. Early workforce projections are critical when launching or scaling a business.
Q: Does offering coverage through multiple plan options affect the 95% calculation?
A: No. The key factor is whether an offer of minimum essential coverage was made to at least 95% of full-time employees and their dependents. Offering multiple plan designs—such as PPO, HMO, or ICHRA options—does not negatively affect compliance, as long as each eligible employee receives a valid offer.
Q: Can payroll system errors lead to Section 4980H(a) Penalties?
A: Absolutely. Incorrect coding of coverage offers, missed deductions, or integration failures between payroll and benefits systems can result in inaccurate Form 1095-C reporting. Even if coverage was properly offered, reporting errors can trigger IRS inquiries. Routine audits of payroll and benefits data help prevent avoidable compliance issues.
