Few things impact your bottom line like an unexpected IRS penalty. When it comes to ACA compliance, fines for late or incorrect filings can be substantial, costing thousands per employee. The best way to protect your business is with a proactive approach, and it all starts with a clear understanding of the timeline. Knowing the ACA reporting deadlines is the critical first step in a strategy that safeguards your company. This guide will walk you through the 2025 dates, common pitfalls, and verification procedures to help you meet the ACA filing deadline with confidence.

Key Takeaways

• Make ACA compliance a year-round habit: Avoid the year-end scramble by maintaining accurate employee data continuously, creating a clear internal process with assigned roles, and using a compliance calendar to track key milestones.
• Prepare for mandatory electronic filing: The threshold for e-filing has dropped to just 10 total returns (including W-2s), meaning most businesses must file electronically by the March 31, 2025 deadline. Remember to provide employees access to their 1095-C forms by March 3.
• Implement a system of checks and balances: Your forms are only as good as your data. Use dedicated ACA software to automate reporting and establish a final verification procedure—like a two-person review—to catch errors before you file and avoid costly penalties.

Breaking Down the 2025 ACA Reporting Requirements

Getting a handle on the Affordable Care Act (ACA) reporting requirements can feel like a major undertaking, but it doesn’t have to be. At its core, ACA reporting is how the IRS verifies that larger businesses are offering their full-time employees affordable, adequate health coverage. If your company meets the size threshold, you’re responsible for filing specific forms with the IRS and providing copies to your employees each year. Think of it as the healthcare equivalent of filing W-2s for payroll.

The process boils down to a few key steps. First, you need to confirm if your business is considered an “Applicable Large Employer” (ALE), as this is what triggers the reporting mandate. From there, you’ll gather information about the health coverage you offered throughout the year and use it to complete Forms 1095-C and 1094-C. These documents provide a month-by-month snapshot of the coverage offered to each employee. Understanding these core components is the first step toward a smooth and successful filing season, helping you stay compliant and avoid costly penalties.

Are You an Applicable Large Employer (ALE)?

Before you dive into any forms, the very first step is to figure out if these rules even apply to you. The ACA reporting mandate is for Applicable Large Employers (ALEs), which the IRS defines as businesses with 50 or more full-time employees, including full-time equivalents (FTEs), on average during the previous calendar year. A full-time employee is someone who works an average of at least 30 hours per week. To calculate your FTEs, you’ll add up all the hours worked by your part-time employees for the month and divide by 120. This calculation is crucial—getting it right determines whether you need to report.

Which ACA Forms Do You Need to File?

If you are an ALE, you’ll be working with two main documents: Form 1095-C and Form 1094-C. Think of Form 1095-C, Employer-Provided Health Insurance Offer and Coverage, as a report card for each employee. You’ll complete one for every full-time employee, detailing the health coverage you offered them for each month of the year. You must send a copy to the employee and file it with the IRS. Form 1094-C, Transmittal of Employer-Provided Health Insurance Offer and Coverage Information Returns, acts as a cover sheet. You’ll file this single form with the IRS to summarize all your 1095-C forms and provide company-level information.

Reporting for Applicable Large Employers (ALEs)

If your business is an ALE, you have a clear reporting mandate. Your primary task is to complete and file Form 1095-C for every single employee who was full-time for any month of the year. This form details the health coverage you offered, how much it cost the employee, and whether they enrolled. You must provide a copy to each employee and file all of them with the IRS. To tie it all together, you’ll also submit a single summary document, Form 1094-C, which acts as a cover sheet for your filings. Managing this process for a large group can be complex, as accuracy is critical to avoid penalties.

Reporting for Small Employers with Self-Insured Plans

Here’s where things can get tricky. Even if you have fewer than 50 employees, you are not automatically exempt from ACA reporting. If your business offers a self-insured or level-funded health plan, you are required to report coverage information. In this scenario, you’ll use a different set of forms: Form 1095-B, which details who was covered and for which months, and the transmittal Form 1094-B. This is a crucial distinction for the growing number of small groups choosing level-funded plans to manage costs. The responsibility for reporting falls directly on you, the employer, not an insurance carrier.

What About Small Employers with Fully Insured Plans?

If your business is not an ALE (fewer than 50 full-time equivalent employees) and you offer a fully insured health plan, you can breathe a sigh of relief. You do not have a direct ACA reporting requirement. In this arrangement, the insurance carrier is responsible for reporting coverage information to the IRS and sending the necessary forms (1095-B) to your employees. This significantly reduces your administrative burden, which is a major reason many smaller companies prefer fully insured plans. Choosing the right plan structure involves weighing factors like cost, flexibility, and compliance, which is where expert guidance becomes invaluable.

Don’t Forget Washington’s State-Specific Rules

Here’s some good news for local businesses: Washington State does not have its own state-level individual mandate or separate reporting requirements. While a handful of other states, like California and New Jersey, require employers to submit similar forms directly to the state government, Washington employers only need to worry about the federal filing requirements set by the IRS. This simplifies your compliance checklist significantly. You can focus all your energy on preparing accurate federal forms without needing to track an additional set of state-specific rules or deadlines. It’s one less administrative burden for you and your team to manage each year.

Washington State

If your business operates only in Washington, your compliance journey is much more straightforward. You don’t have an extra set of state-specific forms or deadlines to manage. Your focus can remain entirely on the federal requirements: providing Form 1095-C to your employees by March 3, 2025, and electronically filing your 1094-C and 1095-C forms with the IRS by March 31, 2025. This streamlined process is a huge advantage, letting you dedicate your resources to a single, accurate federal submission without the complexity that businesses in other states face.

California

California, on the other hand, has its own state-level individual mandate, creating an additional reporting obligation for employers. If you have employees there, you’ll need to file health coverage information with the state’s Franchise Tax Board. The deadlines are different, too. You must provide the forms to your California employees by January 31, 2026, and file electronically with the state by March 31, 2026. This is a perfect example of how operating in multiple states adds another layer of administrative work to your annual compliance checklist.

District of Columbia (D.C.)

The District of Columbia also requires employers to report health coverage information directly to its Office of Tax and Revenue. For the 2025 tax year, you’ll need to provide these forms to your D.C.-based employees by March 2, 2026. After that, your electronic filing is due to the city’s tax office by April 30, 2026. For any business with employees in multiple locations, keeping a close eye on these varying local rules is essential for avoiding penalties at both the federal and district levels.

Massachusetts

Massachusetts has one of the longest-standing individual mandates and a unique reporting process to match. Employers there must provide employees with a specific state form, the Form MA 1099-HC, to prove they had access to creditable health coverage. Unlike the federal system, the deadlines for providing this form to employees and filing it with the Massachusetts Department of Revenue are the same: February 2, 2026. This distinct form and earlier deadline really highlight how much compliance requirements can differ from the federal standard.

New Jersey

New Jersey also has an individual mandate with its own set of reporting requirements. If you have employees in the state, you must submit health coverage information to the New Jersey Division of Taxation. The deadline for getting the required forms to your employees is March 2, 2026. While the state conveniently aligns its electronic filing deadline with the federal one—March 31, 2026—it’s important to remember this is still a completely separate submission that your team must prepare and file to stay compliant.

Rhode Island

Rhode Island is another state where employers must report health coverage information directly to the state’s tax authority. This requirement runs parallel to your federal ACA filing duties. For the 2025 tax year, you must provide coverage information to your Rhode Island employees by March 2, 2026. The deadline to file this information electronically with the Rhode Island Division of Taxation is March 31, 2026. For those of us managing benefits in Washington, this is another great reminder of the simplified compliance environment we get to work with.

How Do Self-Insured Plans Affect Reporting?

If your business offers a self-insured health plan, your reporting responsibilities are slightly different. Unlike fully insured plans where the insurance carrier handles part of the reporting, self-insured employers are responsible for completing all sections of Form 1095-C. This includes the part that details the coverage for every individual enrolled in the plan—not just the employee, but their spouse and dependents, too. A helpful update provides some relief: if you’ve made a reasonable effort but can’t obtain a Social Security Number (SSN) for a dependent, you can now use their date of birth on the form instead of leaving it blank.

Don’t Miss These 2025 ACA Filing Deadlines

When it comes to ACA reporting, timing is everything. Missing a deadline isn’t just a minor slip-up; it can lead to significant financial penalties and a lot of unnecessary stress for your team. The key is to know the dates well in advance and work backward to create a manageable timeline. Think of these deadlines as non-negotiable appointments with the IRS and your employees. Getting them on your calendar now is the first step toward a smooth and successful filing season.

Here are the critical dates you need to know for the 2024 tax year, which you’ll be reporting on in 2025.

When Should You Distribute Forms to Employees?

Your first major deadline is providing Form 1095-C to each of your full-time employees. The due date for this is March 3, 2025. This form details the health coverage you offered them throughout the year. It’s essential information your employees need to complete their own tax returns, so getting it to them on time is a crucial part of the process. Make sure you have a solid plan for printing and distributing these forms, whether by mail or secure electronic delivery, well before the March deadline arrives.

The 2025 Deadline for Filing by Mail

If your business is filing fewer than 10 returns in total (including forms like W-2s and 1099s), you have the option to file your ACA forms on paper. The deadline for submitting paper Forms 1094-C and 1095-C to the IRS is February 28, 2025. Notice that this date is slightly earlier than the deadline for distributing forms to your employees. Because the threshold for paper filing is so low, most businesses will need to file electronically, but it’s an important date to know if it applies to your organization.

The 2025 Deadline for E-Filing with the IRS

For the vast majority of businesses, electronic filing is mandatory. If you are filing 10 or more returns of any type, you must submit your ACA forms electronically. The deadline for e-filing Forms 1094-C and 1095-C with the IRS is March 31, 2025. This is the final and most common deadline for getting your reporting done. Using an IRS-approved software provider is essential for this step, as it ensures your data is transmitted securely and in the correct format.

Key Thresholds for 2026

Beyond the filing deadlines, staying compliant means keeping an eye on a few key numbers that the IRS updates periodically. These thresholds determine whether the health coverage you offer is considered “affordable” and provides “minimum value.” Getting these calculations right is just as important as filing on time, as they are central to avoiding the kind of penalties that can seriously impact your budget. For the 2026 reporting year, there are specific figures you’ll need to incorporate into your benefits planning. Understanding these metrics will ensure your strategy is sound, your company is protected, and your employees receive the quality coverage they expect.

The Affordability Threshold

For 2026, the IRS has set the affordability threshold at 9.96% of an employee’s household income, a notable increase from the previous year’s 9.02%. In simple terms, your health plan is considered affordable if the amount an employee pays for the lowest-cost, self-only plan doesn’t exceed this percentage. This adjustment is critical because it directly impacts how you structure employee premium contributions. As you design your benefits package for the upcoming year, you’ll need to use this new percentage to ensure your offerings remain compliant and help your employees avoid any potential tax credit complications on their personal returns.

The Minimum Value (MV) Standard

The Minimum Value (MV) standard is all about the quality of the coverage you provide. To meet the ACA’s requirements, your health plan must cover at least 60% of the total allowed cost of benefits. This standard ensures that the plan isn’t just a “bare-bones” policy but offers substantial coverage for essential health services, giving your team real financial protection. This 60% threshold remains a critical benchmark for 2026. Ensuring your plan design meets this standard is a fundamental part of your compliance strategy and a key factor in offering a competitive benefits package. Partnering with an expert can help you evaluate your plan options to confirm they meet this important requirement.

How to Request a Filing Extension

If you’re worried you won’t be able to meet the IRS filing deadline, you can request a 30-day extension. To do this, you’ll need to submit Form 8809, Application for Extension of Time to File Information Returns, by the original due date. It’s important to know that this extension only applies to the deadline for filing with the IRS, not the deadline for furnishing forms to your employees. While the IRS has offered automatic extensions in the past, you shouldn’t count on them. Proactively filing for an extension is the only way to be sure.

Simple Tips to Meet Every ACA Deadline

The secret to a stress-free filing season is simple: don’t wait until the new year to start. The best practice is to begin gathering and verifying your employee data in the third or fourth quarter of the year. This includes confirming full names, Social Security numbers, hours worked, and the employee cost for health coverage each month. By collecting this information throughout the year, you can catch errors early and avoid a last-minute scramble. A dedicated partner can help you establish a clear process, making data collection and verification a seamless part of your workflow.

How to Gather the Right Information for ACA Forms

Getting your ACA forms right starts with gathering the right information. It might feel like a lot of data to pull together, but breaking it down makes the process much more manageable. Think of it as building with blocks—you just need to find the correct pieces and put them in the right order. The key is to be meticulous and start early. Having accurate, complete data on hand is the single best way to ensure a smooth filing process and avoid those dreaded penalty notices from the IRS. Let’s walk through exactly what you need for each form and how to make sure your information is clean, correct, and ready to go.

What Goes on Form 1095-C?

Think of Form 1095-C as an individual report card for each of your full-time employees. You’ll need to complete one for every person who was a full-time employee for any month of the year. This form tells the employee and the IRS about the health coverage you offered them. You’ll need to include the employee’s name, address, and Social Security number. The form also requires details about the coverage you offered, including which months it was available and the monthly premium for the lowest-cost, self-only plan you provided. The IRS provides detailed instructions that can help clarify any specific questions about the required codes and information for this form.

What Goes on Form 1094-C?

If the 1095-C is the individual report card, then Form 1094-C is the cover sheet for the whole class. This transmittal form summarizes all the 1095-C forms you’re filing. It provides the IRS with information about you, the employer. You’ll need to include your company’s name, address, and Employer Identification Number (EIN). This form also reports the total number of 1095-C forms you are submitting and confirms that you, as an Applicable Large Employer (ALE), offered coverage to your employees. It’s essentially the summary document that ties everything together, so it’s crucial that the information here matches the collective data from your individual 1095-C forms.

Smarter Ways to Collect Employee Data

The quality of your filing depends entirely on the quality of your data. The best approach is to maintain clean records throughout the year, not just scramble when deadlines are near. Start by ensuring all employee data is up-to-date, including full legal names, Social Security numbers, and current addresses. If you use a payroll service, see if it offers a portal where employees can review and update their own information. This not only saves you time but also places the responsibility on employees to confirm their details are correct. An annual data audit before reporting season can also help you catch any inconsistencies early.

Collecting Dependent Social Security Numbers (SSNs)

If your business has a self-insured health plan, your data collection duties go a step further. You are responsible for reporting coverage details for every individual on the plan—not just the employee, but their spouse and dependents as well. This requires you to collect their full names, dates of birth, and Social Security numbers. Asking employees for their family’s SSNs can be a sensitive task, but the IRS provides a practical solution if you run into trouble. If you’ve made a reasonable effort to get a dependent’s SSN without success, you can use their date of birth on the form instead. This effort usually means making at least three documented requests, which helps you stay compliant even when you can’t track down every piece of information.

How to Verify Your Information is Correct

Before you submit anything, take the time to verify your data. This simple step can save you from major headaches and potential penalties down the road. Cross-check the information on your forms against your payroll records and benefits administration system to ensure everything aligns. Do the employee names and SSNs match exactly? Are the coverage offer codes correct for each month? It’s helpful to have a second person on your team review the forms for accuracy. If you’re feeling overwhelmed by the details, this is an area where a dedicated benefits partner can make a huge difference. We can help you get started with a system that makes verification straightforward.

Avoid These Common ACA Reporting Errors

A few common mistakes trip up employers year after year. One of the biggest is inaccurate or mismatched employee information, especially names and Social Security numbers. Another frequent error is simply filing after the deadline has passed. It’s also easy to use the wrong codes on Form 1095-C, which can misrepresent the coverage you offered. To avoid these issues, familiarize yourself with the requirements well before the deadlines. Create a checklist, follow a clear timeline, and don’t be afraid to ask for help. Understanding the common pitfalls is the first step toward preventing them and ensuring your company remains compliant.

Miscalculating Affordability with Opt-Out Payments

Offering a cash payment to employees who opt out of your health plan might seem like a straightforward way to manage costs, but it can create a serious compliance trap. Certain opt-out payments can increase what the IRS considers an employee’s required contribution, potentially making your otherwise affordable coverage “unaffordable” in their eyes. The rules hinge on whether the payment is unconditional—given to any employee who declines coverage—or conditional, which usually requires proof of other coverage. Unconditional payments are often added to the employee’s premium share, which can easily push your plan past the official affordability threshold. Getting this calculation wrong is a common and costly error, making it essential to understand exactly how these arrangements impact your reporting.

Tracking Hours for Remote and Hybrid Workers

With more employees working remotely or on flexible schedules, accurately tracking their hours has become a significant challenge for many businesses. This isn’t just a payroll issue; it’s a critical component of ACA compliance. The hours your employees work are the foundation for determining your company’s ALE status and identifying which employees are considered full-time. Inconsistent or inaccurate tracking can lead you to miscalculate your full-time equivalents (FTEs), potentially causing you to misclassify your business size or fail to offer coverage to an eligible employee. It’s crucial to have a reliable system for logging all hours worked, regardless of where your team is located, to ensure your full-time employee count is accurate for reporting.

How to Stay Compliant and Avoid ACA Penalties

Navigating the world of ACA reporting can feel like a tightrope walk, and the fear of penalties for a misstep is very real. The IRS enforces these rules strictly, and non-compliance can lead to significant fines that impact your bottom line. But thinking about penalties isn’t about causing stress; it’s about understanding the stakes so you can build a solid compliance strategy. Getting your forms in on time is just one piece of the puzzle—the information on them has to be accurate, too.

Mistakes happen, but some are more costly than others. The difference between a simple error and what the IRS considers intentional disregard can be thousands, or even millions, of dollars in fines. That’s why it’s so important to have a clear process for gathering, verifying, and filing your information. By staying organized and proactive, you can protect your business from these avoidable costs. Let’s walk through the specific penalties, what they mean for your business, and how you can create a plan to stay on the right side of compliance. With the right approach, you can handle your ACA reporting with confidence.

What Happens If You Miss an ACA Filing Deadline?

Meeting deadlines is non-negotiable when it comes to ACA reporting. If you fail to provide Form 1095-C to your employees on time, you could face a fine of up to $310 for each form in 2025. The same penalty applies if you miss the deadline for filing those forms with the IRS. These individual fines can add up quickly, especially for larger businesses. The total penalty for a calendar year can reach a staggering maximum of $3,987,000 for late or incorrect forms. This underscores just how critical it is to have your reporting calendar mapped out well in advance and to stick to it without fail.

The Cost of Inaccurate ACA Reporting

Filing on time isn’t enough; the information you submit must also be correct. The IRS can issue the same steep penalties for forms that contain errors, such as incorrect employee names, mismatched Social Security numbers, or inaccurate coverage information. This means your responsibility extends beyond just hitting a deadline. You must make a diligent effort to ensure every detail on every form is accurate. Establishing a system to cross-reference your payroll and benefits data is a great first step. Taking the time to verify information throughout the year can save you from costly fines and headaches when filing season arrives.

Penalty for Not Offering Coverage (4980H(a))

This is often called the “sledgehammer penalty” for a reason. If your business is an Applicable Large Employer (ALE) and fails to offer minimum essential coverage to at least 95% of your full-time employees and their dependents, you could face a significant fine. The penalty is triggered if even one full-time employee receives a tax credit from the healthcare marketplace. For 2025, this fine is calculated at $3,340 per full-time employee, after excluding the first 30 employees from the calculation. This isn’t just a fine for the one employee who went to the marketplace; it’s applied across your entire full-time workforce, making it a potentially devastating financial blow for non-compliance.

Penalty for Offering Unaffordable Coverage (4980H(b))

Simply offering a health plan isn’t enough—it also has to be affordable and provide minimum value. If you offer coverage that doesn’t meet these standards, you could face the 4980H(b) penalty. This fine is triggered when an employee rejects your company’s plan because it’s unaffordable and instead receives a tax credit from the marketplace. The penalty is $5,010 per affected employee who receives that credit. Unlike the sledgehammer penalty, this one is calculated on a per-employee basis, but it can still add up quickly. Ensuring your plan design is compliant is a critical step that requires careful planning and expert guidance.

Penalties for Incorrect or Late Forms

Even if you offer a perfect, affordable health plan, you can still face penalties for administrative mistakes. The IRS can issue the same steep fines for filing forms with errors—like mismatched Social Security numbers or incorrect coverage codes—as they do for missing the deadline entirely. This means your responsibility extends beyond just offering a compliant plan; you must also ensure your reporting is flawless. A single mistake on a form can be costly, which is why having a system of checks and balances is so important. Taking the time to verify information throughout the year can save you from costly fines and headaches when filing season arrives.

Penalties for Intentional Disregard

This is the most severe category of penalties, reserved for employers who the IRS determines have knowingly ignored the ACA reporting rules. If your failure to file correctly is deemed to be intentional, the penalty is at least $680 per form, with no maximum limit. This means the potential fines could be astronomical, far exceeding the standard penalties for late filing or simple errors. The IRS takes compliance seriously, and this penalty underscores the importance of making a good-faith effort to file accurately and on time. Documenting your process and demonstrating diligence is your best defense against such a claim.

What is “Good Faith” Relief?

In the past, the IRS offered “good faith relief,” which protected employers from penalties if they could show they made a genuine, albeit unsuccessful, attempt to comply. However, this relief has been phased out. Now, the focus is on accuracy and timeliness. If the IRS determines you intentionally disregarded your reporting responsibilities, the penalties are severe—starting at a minimum of $660 per form with no maximum cap. On the bright side, there are reduced penalties for making swift corrections. If you identify and fix an error within 30 days of the deadline, the penalty drops to $60 per return, showing that prompt action is always the best policy.

Reduced Penalties for Quick Corrections

The IRS understands that mistakes can happen, and they incentivize businesses to fix them quickly. If you discover an error on your forms after you’ve filed, prompt action is your best defense against larger fines. The penalty structure is tiered, meaning the sooner you correct the mistake, the less you’ll pay. For example, if you identify and fix an error within 30 days of the filing deadline, the penalty can drop to just $60 per return. This shows that being proactive and diligent about your compliance, even after submission, can significantly reduce the financial impact of an honest mistake.

Requesting Relief for Reasonable Cause

In some situations, the IRS may waive penalties entirely if you can demonstrate “reasonable cause.” This means you need to show that you made a genuine effort to comply and the failure was due to events beyond your control. For instance, this could apply if your office was affected by a natural disaster or if you received incorrect information from a third-party vendor despite your due diligence. To make a case for reasonable cause, you’ll need to provide a clear, written explanation and have documentation to back up your claim. This is where having a partner who helps you maintain meticulous records can be a lifesaver, ensuring you have the proof you need to get started on the right foot.

Proactive Steps to Prevent Penalties

The best way to deal with penalties is to avoid them altogether. Proactive preparation is your strongest defense. Start gathering and organizing your data long before the deadlines approach—ideally, as soon as the previous reporting year closes. Make it a standard practice to verify all employee information, including full legal names, Social Security numbers, and current addresses. A simple data audit can catch errors before they become expensive problems. By embedding these verification steps into your regular HR and payroll processes, you can ensure your data is clean and ready to go when it’s time to file.

Using IRS Safe Harbors and Simplified Reporting

The IRS knows you can’t possibly know every detail of your employees’ financial lives, like their total household income. To make ACA compliance more practical, they’ve created several “safe harbors” and simplified reporting methods. Think of these as approved shortcuts that help you prove you’ve offered affordable coverage without needing information you don’t have access to. Using these tools isn’t just about making your life easier; it’s a strategic way to reduce your risk of penalties. By understanding which options are available, you can choose the most efficient path for your business, saving time and ensuring you meet your obligations correctly.

Affordability Safe Harbors

For your health plan to be considered “affordable,” the cost for your employee’s lowest-cost, self-only plan can’t be more than a certain percentage of their household income—a figure that adjusts annually. The challenge is that you don’t know their total household income. This is where affordability safe harbors come in. The IRS allows you to use information you already have to test for affordability. The three most common methods are the W-2 Safe Harbor, which uses the employee’s W-2 wages; the Rate of Pay Safe Harbor, based on their hourly or monthly salary; and the Federal Poverty Line Safe Harbor. Choosing the right one helps you confidently demonstrate compliance without the guesswork.

Streamlined Reporting Options

The IRS has also introduced ways to simplify the reporting process itself. For instance, employers are no longer required to furnish a copy of Form 1095-C to every single full-time employee. Instead, you can post a clear and accessible notice on your company’s benefits website by early March, letting employees know they can request a copy. This can significantly cut down on printing and mailing costs. Additionally, if you have a self-insured or level-funded plan, it’s important to remember you are responsible for reporting exactly who was covered under the plan and for which months. Staying on top of these reporting options ensures you’re working efficiently and meeting all your specific obligations.

What’s New for ACA Reporting in 2025?

The rules surrounding the Affordable Care Act (ACA) are always evolving, and keeping up with the latest changes is essential for staying compliant. For the 2025 reporting season, which covers the 2024 calendar year, there are a few key updates you’ll want on your radar. These changes affect how you distribute forms, the technology you use to file, and even the timeline for potential penalties.

Understanding these new requirements ahead of time helps you plan your strategy and avoid last-minute stress. From new electronic filing mandates to shifts in how you communicate with employees, these updates are designed to streamline the process but require some adjustments on your end. Let’s walk through exactly what’s different this year so you can feel confident as you prepare for filing season.

A Look at New ACA Requirements

As you plan for the year ahead, remember that employers who report under the ACA must prepare for deadlines in early 2025. The core responsibility remains the same: to report health coverage information for your employees to the IRS and to provide a statement to your full-time employees. The key is to start early. Don’t wait until January to think about this. Getting your data and processes in order now will save you from a major headache when the deadlines are right around the corner.

IRS Enforcement Focus for 2026

Looking ahead, the IRS is sharpening its focus on ACA compliance for the 2026 reporting season. The agency is paying close attention to accurate reporting, ensuring employers meet their shared responsibility obligations, and correctly administering Health Savings Accounts (HSAs) and high-deductible plans. With “good faith” relief now a thing of the past, the margin for error has all but disappeared. The IRS can issue the same steep penalties for forms containing errors—like mismatched Social Security numbers or incorrect coverage codes—as it does for missing deadlines entirely. This shift makes proactive preparation your strongest defense. Ensuring your data is clean and your reporting is precise isn’t just good practice; it’s an essential part of getting started with a strategy that protects your business from avoidable fines.

Are There New Rules for Distributing Forms?

Here’s some good news: employers are no longer required to automatically furnish a copy of Form 1095-C to every single full-time employee. Instead, you must provide a clear and conspicuous notice that the form is available upon request. You still have to prepare the forms and file them with the IRS, but this change can reduce printing and mailing costs. Just be sure you have a solid process in place to quickly fulfill employee requests for their forms when they come in.

Understanding Changes to the Penalty Structure

The IRS has clarified its timeline for assessing ACA penalties. There is now a six-year statute of limitations, which starts from the date your return was due or filed. This gives the IRS a much longer window to review your filings and issue penalties for non-compliance. This extended timeframe makes accurate record-keeping and timely filing more important than ever. Holding onto your documentation and ensuring your data is correct from the start is your best defense against potential issues down the road.

Do You Need New Tech for ACA Filing?

This is a big one for many businesses. The threshold for mandatory electronic filing has been significantly lowered. If you file 10 or more returns in total during the calendar year—including forms like W-2s and 1099s, not just ACA forms—you must now file your ACA forms electronically. Since most businesses easily meet this 10-return threshold, paper filing is effectively no longer an option for the vast majority of employers. It’s time to make sure you have the right software or partner to handle electronic submission.

How to Streamline Your Reporting Process for 2025

To avoid the stress of looming deadlines and potential errors, the best thing you can do is start early. Begin gathering and auditing your employee data—like names, Social Security numbers, hours worked, and coverage costs—in the third or fourth quarter of the year. This gives you plenty of time to catch and correct mistakes before they become a real problem. A proactive approach not only prevents penalties but also makes the entire reporting process smoother for your team.

Choosing the Right Tools for a Smooth Filing Season

ACA reporting can feel like a massive puzzle, but having the right tools and systems makes all the pieces fit together smoothly. Instead of scrambling at the last minute, you can build a process that makes filing feel routine, not revolutionary. Think of it as setting up your command center for compliance. This isn’t just about buying software; it’s about creating a reliable workflow that saves you time, reduces stress, and protects your business from costly penalties.

A solid strategy involves more than just filling out forms. It starts with clean data, relies on smart technology, and ends with thorough checks and balances. When your systems are in place, you can track employee eligibility, monitor hours, and generate accurate reports throughout the year. This proactive approach means you won’t be digging through spreadsheets and payroll records in a panic come January. Instead, you’ll have the information you need right at your fingertips. By investing a little time in setting up the right tools now, you’re giving your team—and your business—the foundation for a successful and penalty-free filing season.

What to Look for in ACA Reporting Software

The right software can be your most valuable player during reporting season. Manual tracking is not only time-consuming but also prone to human error. Dedicated ACA reporting software automates the heavy lifting, from tracking employee hours and eligibility to populating and filing your 1094-C and 1095-C forms. This automation is key to meeting deadlines and minimizing the administrative load on your HR team. There are many excellent ACA reporting software solutions available that can simplify compliance and integrate with your existing payroll and benefits systems, making the entire process more efficient.

How to Set Up Your Data Management System

Your ACA forms are only as accurate as the data you put into them. That’s why a robust data management system is non-negotiable. Your payroll, HR, and benefits platforms should work together to ensure all employee information—from social security numbers to hours worked—is consistent and correct. Many payroll processing companies offer online portals where employees can review and update their personal details, which helps catch errors early. Centralizing your data prevents discrepancies and ensures you have a single source of truth when it’s time to generate your reports, saving you from the headache of last-minute corrections.

Can Software Help You Monitor Compliance?

Filing your forms with the IRS shouldn’t feel like sending them into a black hole. Modern compliance tools offer much-needed transparency throughout the submission process. After you e-file, you shouldn’t have to wonder if your forms were received or accepted. Many online ACA reporting tools provide real-time status updates directly from the IRS, confirming whether your submission was successful or if there are issues that need your attention. This immediate feedback loop is invaluable, allowing you to correct any problems quickly and ensuring you remain in good standing with the IRS.

A Simple System for Keeping Documents in Order

Good record-keeping is your best defense in the event of an audit. Beyond the forms themselves, you need to maintain documentation that supports your filings, including records of coverage offers, employee waivers, and calculations for determining full-time status. It’s a best practice to keep all documents related to your Forms 1095-C and 1094-C filings for at least three years. Create a dedicated digital folder for each reporting year to store everything securely. This organization will not only make future filings easier but also provide peace of mind knowing you’re prepared for any inquiries.

Why You Need Quality Control Checks (and How to Start)

Before you submit your forms, a final quality control check is essential. A simple typo in a name or social security number can trigger an error notice and potential penalties. Failing to follow ACA reporting requirements can lead to steep fines, so it’s worth taking the extra time to verify everything. Implement a review process, whether it’s having a second team member double-check the data or running a final audit report through your software. This step is your last line of defense against costly mistakes and ensures the information you send to the IRS and your employees is completely accurate.

How to Prepare Your Business for ACA Reporting Season

Getting ready for ACA reporting isn’t just a task for the end of the year; it’s a continuous process. By breaking it down into manageable steps and staying organized, you can approach filing season with confidence instead of stress. A proactive strategy ensures your data is clean, your team is prepared, and you meet every deadline without a last-minute scramble. Think of it as building a strong foundation that will support your business year after year. Here’s how you can set your team up for a smooth and successful reporting cycle.

Why Year-Round Data Management is a Game-Changer

The key to stress-free ACA reporting is maintaining accurate employee data all year long. Waiting until the last minute to clean up records often leads to errors, which can result in costly penalties and the hassle of reissuing forms. Make it a habit to regularly review employee information, including names, social security numbers, addresses, and coverage dates. If you work with a payroll provider, see if they offer an online portal where employees can review and update their own information. This not only empowers your team but also reduces the administrative burden on your HR staff. Consistent data management is the single best way to ensure your forms are correct the first time.

How to Create a Clear Internal Reporting Process

A well-defined internal process turns a complex task into a predictable workflow. Start by outlining every step, from gathering data to filing the final forms. Assign clear responsibilities to specific team members in your HR, payroll, and benefits departments so everyone knows their role. Your process should document where to find necessary information, how to handle mid-year employee status changes, and who gives the final approval before submission. Whether you manage benefits for small groups or large ones, a documented plan eliminates confusion and ensures that critical tasks don’t fall through the cracks, creating a repeatable system you can rely on every year.

Getting Your Team Ready for ACA Filing

Your people are your greatest asset in the compliance process, but they need the right knowledge to be effective. Ensure your HR and payroll teams understand the fundamentals of ACA reporting, including what the forms require and why the information is important. You don’t need to make them legal experts, but they should be comfortable with the terminology and deadlines. Consider holding a brief training session or creating a simple guide with key dates and definitions. When your team feels confident in their understanding, they’re better equipped to spot potential issues early. Having access to expert guidance can also provide peace of mind, giving your team a resource to turn to with questions.

Build Your Own ACA Compliance Calendar

Deadlines can sneak up on you. A compliance calendar is a simple yet powerful tool to keep your team on track. Go beyond just noting the final filing dates; map out your entire reporting timeline with internal milestones. Set deadlines for when data collection should be complete, when forms need to be reviewed, and when they should be sent to employees. Be sure to include both federal and any state-specific deadlines. By visualizing the entire process, you can allocate resources effectively and prevent the last-minute rush that often leads to mistakes. This calendar will become your roadmap for a timely and accurate filing season.

Simple Steps to Verify Your ACA Data

Even with the best data management practices, errors can happen. That’s why a final verification step is so important. Before you file, you must make a good-faith effort to ensure all information is correct. This means double-checking everything from employee social security numbers to the offer of coverage codes you used on Form 1095-C. Implement a review process where at least two people check the forms for accuracy and completeness. A second pair of eyes can often catch simple typos or inconsistencies that were missed the first time. This final quality check is your last line of defense against potential penalties and is well worth the extra time.

Frequently Asked Questions

How do I know if my business even needs to worry about ACA reporting? The requirement comes down to whether your business is considered an Applicable Large Employer, or ALE. The general rule is that if you had an average of 50 or more full-time employees, including full-time equivalents, during the previous calendar year, then these reporting rules apply to you. It’s not about how many employees you have right now, but your average from last year, so it’s a calculation you should run annually.

What’s the biggest change I need to be aware of for the 2025 filing season? The most significant update is the new electronic filing threshold. If your business files 10 or more information returns of any kind—including W-2s and 1099s—you are now required to file your ACA forms electronically with the IRS. Since most businesses easily meet this low threshold, it effectively means that paper filing is no longer an option for the vast majority of employers.

I’ve heard I no longer have to mail Form 1095-C to every employee. Is that correct? Yes, that’s true, but with an important condition. You are no longer required to automatically furnish a copy of the form to every employee. However, you must provide a clear and prominent notice on your website stating that the form is available upon request. You still need to prepare a 1095-C for every full-time employee and have a system ready to provide it to them promptly if they ask for it.

What’s the most common mistake you see businesses make, and how can I avoid it? The most frequent and costly errors stem from inaccurate employee data, especially mismatched names and Social Security numbers. These simple typos can lead to rejected filings and penalties. The best way to avoid this is to stop treating data collection as a once-a-year task. Instead, build a process to verify employee information throughout the year, perhaps during onboarding and open enrollment, to ensure your records are always clean and up-to-date.

My business is in Washington. Are there any extra state-level forms I need to file? Thankfully, no. Washington State does not have its own individual health insurance mandate or any additional state-level reporting requirements for employers. This simplifies your compliance checklist quite a bit, as you only need to focus on meeting the federal filing deadlines and requirements set by the IRS.
