A Practical Guide to 2026 ACA Reporting Requirements

Let's be honest: ACA reporting for 2026 can feel like a maze of confusing forms, shifting deadlines, and high-stakes penalties. But it doesn’t have to be a source of anxiety. At its core, ACA reporting is how employers show the IRS—and their employees—that they've offered compliant health coverage throughout the year.

This process is especially critical for Applicable Large Employers (ALEs), as it’s a non-negotiable part of modern healthcare compliance.

Your Roadmap to 2026 ACA Reporting

Think of ACA reporting less as a once-a-year scramble and more like a continuous cycle. It’s a year-long process of tracking employee data that all comes together when you file specific forms with the IRS. Essentially, it's the government's system for verifying that companies are upholding their end of the bargain by offering affordable, quality health coverage to their full-time teams.

For the upcoming 2026 reporting season, which covers the 2025 calendar year, the deadlines are firm. You’ll need to provide Form 1095-C to your employees by March 2, 2026. Then, your electronic filing of Forms 1094-C and 1095-C is due to the IRS by March 31, 2026.

And a heads-up: the days of paper filing are nearly over. If you’re filing 10 or more information returns of any kind, you’re now required to submit your ACA forms electronically.

2026 ACA Reporting at a Glance

Keeping these dates and duties straight is half the battle. Missing a deadline, even by accident, can lead to some painful penalties.

To help you stay organized, here's a quick look at the key requirements for the 2025 reporting year, with deadlines falling in 2026.

Requirement	Who It Applies To	Key Deadline (2026)	Associated Forms
Furnish Employee Statements	Applicable Large Employers (ALEs)	March 2, 2026	Form 1095-C
File with IRS (Electronic)	ALEs (filing 10+ returns)	March 31, 2026	Forms 1094-C & 1095-C
Furnish Coverage Statements	Self-insured Small Employers	March 2, 2026	Form 1095-B
File with IRS (Electronic)	Self-insured Small Employers	March 31, 2026	Forms 1094-B & 1095-B

This table gives you a high-level view, but there's always more to learn about the fundamentals.

From Manual Headaches to Automated Peace of Mind

Instead of drowning in spreadsheets, modern platforms can turn this entire compliance chore into a smooth, automated process. Imagine having a dashboard that gives you a clear, real-time snapshot of your ACA status at any point during the year.

This kind of visual oversight helps HR teams spot potential red flags—like an employee about to hit full-time status—long before they become filing-season emergencies. Partnering with a benefits and compliance expert like Benely can automate data collection, populate forms correctly, and ensure you’re on track from day one, helping you avoid those dreaded penalty notices.

How to Determine if You Are an Applicable Large Employer

Before you dive into forms and deadlines, the first and most critical question is simple: do the main ACA reporting requirements even apply to your business? The answer hinges on whether you’re considered an Applicable Large Employer (ALE).

Getting this right is your first major hurdle. Misclassifying your business is a common and costly mistake, so it’s essential to nail this down from the start.

In a nutshell, an ALE is any company that had an average of 50 or more full-time employees—including full-time equivalent employees—during the previous calendar year. So for the 2026 reporting season, you'll be looking back at your 2025 payroll data.

This is especially crucial for growing businesses. Crossing that 50-employee line is a major milestone, and it completely changes your compliance responsibilities. As your business scales, understanding how your obligations shift is key. You can learn more about how insurance needs evolve as your company grows and prepare for what’s ahead.

Calculating Your Full-Time Equivalent Employees

The phrase "including full-time equivalent employees" is where many employers get tripped up. It's not just a simple headcount of your full-time staff. You also have to account for all the hours worked by your part-time team members.

Think of it like getting your final employee count by combining two key ingredients.

Here’s a straightforward breakdown of the math:

1. Count Your Full-Time Employees: For each month of last year, count every employee who worked an average of 30 hours per week or 130 hours per month.
2. Calculate Your Full-Time Equivalents (FTEs): Next, add up the total hours worked by all your non-full-time employees (part-time, seasonal, etc.) for that same month.
3. Divide by 120: Take that total number of part-time hours and divide it by 120. This gives you your FTE count for the month.
4. Add Them Together: For each month, simply add your full-time employee count (Step 1) to your new FTE count (Step 3).

To get your final ALE status, you add up the total counts from all 12 months and divide that sum by 12. If that final average is 50 or more, congratulations—you're an ALE for the current year.

Putting the ALE Calculation into Practice

Let's walk through a clear scenario. Imagine a landscaping company that has a lot of seasonal workers on its payroll during 2025.

Example Scenario:

• Full-Time Employees: The company has 40 full-time employees who consistently work well over 30 hours a week all year.
• Part-Time Hours: In the busy month of July, its five part-time office staff each work 80 hours, and ten seasonal workers each put in 100 hours. This comes out to 1,400 part-time hours for July ( (5 * 80) + (10 * 100) ).
• FTE Calculation: Divide the 1,400 part-time hours by 120, which equals 11.67. The IRS requires you to round this down, so it becomes 11 FTEs.
• Total for July: For that month, the company adds its 40 full-time employees to its 11 FTEs for a total of 51 employees.

If the company repeats this calculation for all 12 months and its average remains 50 or higher, it officially becomes an ALE for the 2026 reporting year. This status means they are on the hook for all ACA reporting and coverage requirements to avoid steep penalties.

Mastering the Core ACA Reporting Forms

So you've figured out your business is an Applicable Large Employer (ALE). Now comes the fun part: the paperwork. This is where all that year-long data tracking gets turned into official ACA reporting forms, and getting them right is non-negotiable if you want to stay compliant. For ALEs, it all boils down to two key documents: Forms 1094-C and 1095-C.

Think of Form 1094-C as the "cover letter" for your company's entire ACA filing. It doesn't go to your employees; this is a transmittal form sent directly to the IRS that summarizes everything on a high level. It certifies that you, as an ALE, offered coverage and provides a snapshot of your total employee counts for each month of the year.

The following flowchart shows how both full-time and part-time employee hours are tallied up to see if a business hits that 50+ employee threshold, which is what triggers these reporting duties in the first place.

As you can see, becoming an ALE isn't just about your full-time staff. You also have to calculate full-time equivalents from part-time hours—a critical step that leads directly to needing these forms.

Decoding the Employee-Specific Form 1095-C

While the 1094-C is for the IRS, Form 1095-C is the individual "report card" you must give to every single person who was a full-time employee for at least one month during the year. This form breaks down the specific health coverage you offered to that employee and their dependents, month by month.

It serves two main purposes. First, it proves to the IRS that you made a valid offer of coverage. Second, it gives your employee the documentation they need about their health plan options for their personal tax filing.

Without a doubt, the most confusing part of Form 1095-C is Part II—specifically lines 14, 15, and 16. These lines use a special "shorthand" of codes to tell the story of each employee's coverage journey throughout the year.

• Line 14 (Offer of Coverage): This is where you use codes (like 1A, 1E, or 1H) to tell the IRS what kind of coverage was on the table each month. For example, Code 1E signals that you offered a plan meeting minimum value to the employee, their spouse, and their dependents.
• Line 15 (Employee Share): Here, you report the employee's monthly premium contribution for the lowest-cost, self-only plan that meets minimum value. This number is absolutely critical for the IRS to run its affordability calculations.
• Line 16 (Safe Harbors & Other Info): This is arguably the most complex line of all. The codes here explain why you shouldn’t face a penalty for a specific employee, even if they turned down your offer or got coverage somewhere else. Code 2C, for instance, means the employee actually enrolled in the coverage offered, while 2A means they weren't employed that month.

Think of these codes as a secret language between you and the IRS. The right combination on lines 14 and 16 paints a clear picture of compliance. The wrong one can trigger automatic penalty notices.

How to Gather Data and Simplify Filing

Populating these forms correctly requires meticulous data from different corners of your business, mainly payroll and benefits administration. You'll need monthly payroll records, benefits enrollment data, employee start and end dates, and exact contribution amounts.

Trying to pull all this together manually is a recipe for errors, headaches, and missed deadlines. This is where having an integrated platform becomes a game-changer. A system like the one from Benely can automatically pull data from your payroll and benefits systems to populate Forms 1094-C and 1095-C for you. This integration practically eliminates the high risk of human error from manual data entry and ensures the right codes are used for each employee’s unique situation.

Ultimately, mastering these forms is less about memorizing every single code and more about having a reliable process. By centralizing your data and using the right tools, you can transform one of the most stressful parts of ACA reporting into a manageable, automated task.

Navigating ACA Affordability and Safe Harbors

When it comes to ACA compliance, just offering health insurance isn’t enough. The plan you offer also has to be “affordable” in the eyes of the IRS, and getting this wrong can lead to some hefty penalties—even if your benefits package is otherwise top-notch.

So, what does “affordable” actually mean? Officially, coverage is affordable if an employee’s contribution for the cheapest self-only plan is less than a certain percentage of their household income. And there’s the catch: you have no real way of knowing an employee’s total household income. This is where the ACA safe harbors become your most valuable compliance tool.

Think of the safe harbors as pre-approved workarounds. Instead of guessing at an employee's total income, the IRS lets you use information you already have—like their W-2 wages or hourly pay rate—to prove your health plan was affordable. By using one of these methods, you’re guaranteed to pass the test.

The Annual Affordability Threshold

Every year, the IRS tweaks the affordability percentage. For the 2026 reporting year, the 2026 ACA affordability threshold has reached its highest level ever, climbing to 9.96 percent. That’s a notable increase from the 2025 rate of 9.02 percent, giving you a bit more breathing room when setting employee contribution amounts. You can read more about how this record-high percentage impacts employers on HR-Works Inc..

This higher threshold means you can potentially ask employees to contribute a little more toward their premiums without running afoul of the rules. Now, let’s get into the three specific safe harbors you can use to prove it.

The Federal Poverty Line Safe Harbor

This is by far the simplest and most straightforward option. To use it, an employee’s monthly premium for your lowest-cost, self-only plan just needs to be less than 9.96% of the current Federal Poverty Line (FPL) for a single person, divided by 12.

• How it Works: You use a single, fixed dollar amount for everyone. No need to calculate anything based on individual wages.
• Best For: Employers who want a simple, one-size-fits-all approach. It’s especially useful if you have a large workforce with lots of hourly or variable-wage employees.

Key Takeaway: The FPL safe harbor is the easiest to administer because it doesn't require employee-specific wage calculations. It offers a clear, bright-line test for affordability across your entire workforce.

The Rate of Pay Safe Harbor

This safe harbor tests affordability based on an employee’s rate of pay at the start of the coverage period. The calculation works a bit differently for hourly and salaried staff.

For Hourly Employees:
Your coverage is affordable if the employee’s monthly premium isn't more than 9.96% of their hourly wage multiplied by 130 hours.

• Example: An employee makes $20/hour. Their monthly affordability target is ($2,600 x 9.96%), or $258.96. As long as you keep their monthly contribution at or below that number, you’re in the clear.

For Salaried Employees:
Your plan is affordable if the monthly premium is no more than 9.96% of their monthly salary.

• Example: A salaried employee earns $4,000 a month. Their affordability threshold is ($4,000 x 9.96%), or $398.40 per month.

This method is generally reliable, but it has one major limitation: you can't use it for an hourly employee if you reduce their rate of pay during the year.

The Form W-2 Wages Safe Harbor

The last option bases affordability on the wages reported in Box 1 of an employee's Form W-2. Your coverage is considered affordable if the employee's total annual premium contribution doesn’t exceed 9.96% of their Box 1 wages for that year.

This method gives you the most flexibility, as it automatically accounts for an employee’s total earnings, including overtime or bonuses. But there's a risk: it's a look-back method. You won’t know for sure if you passed the test until after the year is over, which can be nerve-wracking if an employee’s wages fluctuate or they take unpaid leave.

Choosing the right safe harbor is a strategic decision that depends on your workforce and risk tolerance. While the FPL method offers simplicity, the Rate of Pay or W-2 methods might let you set higher employee contributions. Platforms like Benely.com can help you model these scenarios, ensuring your contribution strategy is both competitive and fully compliant with ACA rules.

How to Avoid Costly ACA Penalties

The financial stakes around ACA reporting aren’t just high—they’re getting higher every year. Failing to get your compliance right can lead to massive IRS penalties that catch even the most well-meaning employers by surprise. Understanding these risks is the first step to building a strategy that protects your company's bottom line.

Think of the two main employer penalties as different tools in the IRS's workshop. One is a sledgehammer for major failures, and the other is a tack hammer for more specific, individual mistakes. Both can do serious damage if you're not careful.

The Sledgehammer and the Tack Hammer Penalties

The first and most severe penalty is the Section 4980H(a) penalty, often called the "sledgehammer." This hammer drops if an Applicable Large Employer (ALE) fails to offer Minimum Essential Coverage (MEC) to at least 95% of its full-time employees and their dependents. If just one full-time employee goes to the marketplace and gets a premium tax credit, the penalty gets triggered for your entire full-time workforce (minus the first 30 employees).

The second is the Section 4980H(b) penalty, or the "tack hammer." This applies when an ALE does offer coverage, but that coverage is either unaffordable or doesn't provide Minimum Value. While less catastrophic, this penalty is still expensive, calculated on a per-employee basis for each full-time employee who receives a premium tax credit.

For 2026, the IRS has significantly raised the stakes. The Section 4980H(a) penalty is now $3,340 per full-time employee annually. The Section 4980H(b) penalty has jumped to $5,010 per affected employee annually. To see how these new figures could affect your business, you can find more detail on the 2026 ACA reporting deadlines from Plante Moran.

Common Mistakes That Trigger ACA Penalties

Most penalties don't come from deliberately ignoring the rules. They pop up from common, avoidable errors that slip through the cracks. Being vigilant about these missteps is your best defense.

Here are the most frequent culprits:

• Misclassifying Employees: Mistakenly labeling a full-time employee as part-time is one of the quickest routes to a penalty, since you likely won't offer them coverage.
• Missing Filing Deadlines: Filing your 1094-C/1095-C forms late or failing to get statements to employees on time will trigger automatic fines.
• Data Inaccuracies: Simple mistakes like typos, wrong Social Security Numbers, or incorrect offer-of-coverage codes on Form 1095-C can easily lead to a penalty notice.
• Failing the Affordability Test: Offering a plan that doesn't meet one of the ACA's affordability safe harbors can trigger the 4980H(b) penalty.

Exploring different compliance management solutions can be a huge help in managing these details and minimizing your risk.

Your Action Plan for Avoiding Penalties

When it comes to ACA compliance, proactive work is always better than reactive damage control. Here is a simple checklist to help you build a stronger, penalty-proof process.

1. Conduct Regular Data Audits: Don't wait until January to find errors. Review your payroll and benefits data monthly or quarterly to confirm employee classifications, hours worked, and contribution amounts are accurate.
2. Master Your Safe Harbors: Before the plan year even starts, choose the affordability safe harbor that best fits your workforce and document your calculations. This gives you solid proof if the IRS ever comes knocking.
3. Establish a Clear Reporting Calendar: Mark every key deadline on your calendar—furnishing forms to employees and filing with the IRS. Start early to give your team plenty of breathing room to gather data and review everything.
4. Partner with an Expert: You don't have to go it alone. Working with a knowledgeable benefits partner like Benely gives you an expert in your corner to verify data, automate filings, and offer guidance on tricky compliance questions.

What is IRS Letter 226J? This is the official notice the IRS sends to inform you that you may owe an Employer Shared Responsibility Payment (ESRP). It’s not a bill—it’s a proposal. You have the right to respond, and the IRS recently extended the response time from 30 to 90 days, giving you more time to prepare a thorough and accurate reply.

Understanding Broader State and Market Trends

Getting federal ACA reporting right is a massive piece of the compliance puzzle, but it’s not the whole story. Your obligations can get a lot more complicated once you factor in state-specific rules and the bigger shifts happening in the healthcare market. For any business with a remote or distributed team, this broader context is absolutely critical.

Staying compliant means looking beyond the federal landscape. A growing number of states have their own individual health insurance mandates, and they come with their own set of reporting duties for employers.

The Growing Patchwork of State Mandates

Several states now require their residents to have health coverage, and they lean on employers to help track compliance. If you have employees in these states, you’ll have extra reporting tasks on top of filing Forms 1094-C and 1095-C with the IRS.

The main states with their own mandates include:

• California: Requires employers to send coverage information to the Franchise Tax Board.
• Massachusetts: Has had its own health insurance requirements for years, complete with unique reporting forms.
• New Jersey: Mandates that employers report coverage details to the Division of Taxation.
• Rhode Island and the District of Columbia also have their own distinct rules.

This complex web of regulations shows just how important it is to have a clear view of your entire workforce, no matter where they live. We share more insights on navigating U.S. healthcare trends to help you prepare for exactly these kinds of challenges.

Staying compliant demands a dual focus: nailing all the federal ACA rules while also satisfying the unique reporting demands of every single state where you have employees. This is where having a centralized compliance strategy becomes non-negotiable.

Major Market Shifts on the Horizon

Beyond state-level rules, bigger economic trends in the healthcare market can directly impact your employees' choices and your overall benefits strategy. One of the most significant changes coming up is the scheduled end of enhanced marketplace subsidies.

As of 2026, nearly 20 million plan selections represent returning customers in the ACA Marketplaces. But 2026 is a big deal because it’s the first time since 2020 that these individuals won't have access to the enhanced premium tax credits that made plans more affordable. This shift will almost certainly make marketplace plans more expensive for millions of people, which could make your company’s health plan look a lot more attractive. For additional details on this trend, you can discover more insights about marketplace enrollment from KFF.

Understanding this dynamic helps HR leaders communicate the true value of the company’s benefits package. It’s also a perfect example of how administrative headaches go far beyond just the ACA. For instance, knowing how to leverage a dedicated Healthcare Virtual Assistant can provide relief by managing other complex rules, like HIPAA.

A proactive partner like Benely.com helps you untangle this complicated patchwork of federal and state regulations, ensuring your reporting is complete and accurate across every jurisdiction where your business operates.

Commonly Asked ACA Reporting Questions

No matter how well you prepare for ACA reporting, a few tricky questions always seem to surface right when you’re in the thick of it. Think of this as your field guide for those "what if" scenarios that can trip up even the most seasoned HR teams.

Getting these details right is the difference between a smooth filing season and a scramble to fix errors down the road. Let's tackle some of the most common points of confusion.

What Is the Difference Between Form 1095-B and 1095-C?

This one trips people up all the time. The two forms sound similar, but they serve completely different purposes.

Form 1095-C is your responsibility as an Applicable Large Employer (ALE). You must send it to every full-time employee, detailing the health coverage you offered them, month by month. It’s the official record of your offer of coverage.

Form 1095-B, on the other hand, is sent by the insurance carrier to prove an individual had at least Minimum Essential Coverage. While your employees might receive a 1095-B from the carrier, this does not replace your legal duty as an ALE to furnish Form 1095-C.

Can I Get an Extension for Filing My ACA Forms?

Yes, but you need to know which deadline you’re extending. There are two separate timelines.

The deadline for furnishing Form 1095-C to your employees (March 2, 2026) already has a permanent 30-day extension baked in, so getting another one is highly unlikely.

However, for the IRS filing deadline, you can request an automatic 30-day extension. To get it, you must file Form 8809 with the IRS by the original due date (March 31, 2026, for e-filing). You can find more details in this guidance from the IRS.

While extensions are an option, relying on them can create a last-minute scramble. A better strategy is to build a proactive reporting calendar and use the right tools to stay ahead from the start.

How Do I Report for Employees Who Terminate Mid-Year?

You absolutely still need to report for them. Your obligation covers every month they were employed and classified as a full-time employee.

On their Form 1095-C, you’ll use specific indicator codes to tell the story of their employment. You'll show which months they worked, what coverage was offered, and when they left the company.

For example, after their termination date, you would use code 2A ("Employee not employed during the month") on Line 16 for all the following months. This is exactly why accurate, month-by-month tracking is so critical—it makes handling these situations straightforward and keeps you compliant.
