ACA Reporting Deadlines for 2025: What You Need to Know

What’s ACA Reporting

The Affordable Care Act, or ACA, reshaped how Americans access and manage healthcare. Passed in 2010, its aim is simple in theory but complex in practice: expand access, raise the quality of care, and slow down the relentless rise in healthcare costs. For HR leaders and employers, ACA’s mission translated into new responsibilities, and a permanent spot on the compliance calendar.

The ACA touches nearly every corner of the benefits landscape:

• Employers: For employers, it’s especially significant. Companies with 50 or more full-time employees (including full-time equivalents), known as Applicable Large Employers (ALEs), must offer affordable health coverage that meets the ACA’s minimum value and essential coverage standards. Failing to do so can trigger penalties that add up quickly. These employers also face annual reporting requirements—Forms 1094-C and 1095-C for ALEs, and 1094-B and 1095-B for smaller or self-insured employers—to demonstrate compliance.
• Individuals: For individuals, the ACA opened doors that didn’t exist before. It expanded Medicaid eligibility, created insurance marketplaces, and introduced subsidies that made coverage accessible to millions who were previously uninsured.
• Insurers: For insurers, it rewrote the rulebook. Health plans must now cover essential health benefits, honor pre-existing conditions, and remove lifetime and annual coverage limits, ensuring that coverage actually delivers when people need it most.

The result is a healthcare system that’s more transparent, but also more complex, and one where compliance, accuracy, and timing matter as much as coverage itself.

ACA Reporting Requirements 2025

Under the ACA employer mandate, Applicable Large Employers (ALEs) — those with 50 or more full-time or full-time-equivalent employees — must report on:

• Health coverage offered to employees, using Forms 1094-C and 1095-C.
• Minimum Essential Coverage (MEC) for self-insured employers (of any size), using Forms 1094-B and 1095-B.

Employers must confirm that each submission includes accurate employee details, coverage months, affordability data, and employer identification. Even small, self-funded employers have limited MEC reporting obligations.

Opportunity: Brokers can turn ACA season into a retention opportunity by guiding clients through these ACA requirements and connecting them with Mitratech Mineral’s expert-vetted ACA resources and reporting tools.

ACA Reporting Deadlines 2025

ACA reporting deadlines can sneak up fast, and for the 2025 reporting year (covering health coverage offered during the 2025 calendar year) the IRS has kept the same familiar schedule. Getting a head start now ensures your data is clean, your process is smooth, and your filings stay penalty-free.

Here are the key dates to keep in mind for ACA reporting due in early 2026:

March 2, 2026 – Deadline to furnish Forms 1095-B and 1095-C to employees

Employers must provide employees with copies of these forms, which summarize the health coverage offered throughout 2025. This documentation helps employees with their own tax filings and demonstrates your organization’s compliance with the ACA’s employer mandate.

February 28, 2026 – Deadline for paper filing with the IRS

Employers filing fewer than 10 total information returns (including W-2s and 1099s) may submit paper copies of Forms 1094 and 1095 to the IRS. Paper filing is now rare but still allowed for small groups that fall below the electronic filing threshold.

March 31, 2026 – Deadline for electronic filing with the IRS

Employers submitting 10 or more total information returns must file electronically. Electronic submission provides a bit of extra time, but accurate preparation early in the year is still the best way to avoid last-minute errors or missed deadlines.

Even for seasoned HR teams, ACA reporting requires precision and attention to detail. The rules don’t change much year to year, but the details do. Deadlines shift, penalty amounts rise with inflation, and a missed update can turn into a major expense. Helping clients stay ahead of those changes is one of the easiest ways for brokers to build trust and deliver real value.

Again, this is where Mitratech Mineral’s ACA Reporting Hub comes in — helping you automate data collection, flag errors early, and file with confidence.

Consequences of Missing ACA Reporting Deadlines

Every broker has seen it happen: a client who meant to get ahead of ACA reporting but blinked… and suddenly it’s March. The forms aren’t filed, the data isn’t clean, and what started as a small oversight becomes an expensive lesson in compliance.

The IRS doesn’t hesitate when it comes to penalties:

• Missing the employee deadline can cost up to $330 per form if Forms 1095-B or 1095-C aren’t furnished on time.
• Late filings with the IRS start at $60 per form if you’re just a few weeks behind, but the fines can rise to $330 per form the longer the delay stretches.
• Incorrect or incomplete data—a missing Social Security number, a mistyped name, a coverage error—can trigger its own set of fines.
• If the IRS determines an employer intentionally ignored their filing duties, penalties can climb to $660 per form with no annual cap.

As you can see, it adds up quickly, especially for larger groups. It’s rarely malicious, it’s usually a matter of time and attention.

ACA Reporting 2025 Checklist

Use this checklist to help your clients (and your own team) get through reporting season smoothly and confidently:

Verify Employee Data

Start by reviewing the basics: names, Social Security numbers, coverage details, and eligibility. A single typo can create hours of extra work or trigger an IRS notice, so accuracy here saves headaches later.

Choose Your Filing Method

Decide early whether you’ll file on paper or electronically. Most employers will need to e-file, so make sure you have access to the right systems or vendors well before the deadline.

Track Your Deadlines

Mark your calendar for every key date — March 3 for employee copies, February 28 for paper filing, and March 31 for electronic filing. Build in reminders a few weeks ahead so nothing sneaks up on you.

Test Before You File

If you’re filing on your own, run a test submission through the IRS AIR system. It’s the easiest way to catch technical errors or formatting issues before they become last-minute crises.

Put Technology to Work

ACA reporting is one of those areas where automation truly pays off. Use a reliable compliance platform to handle form creation, validation, and submission… no more spreadsheets or manual uploads.

Align Your Team

Make sure HR, payroll, and benefits are on the same page about who’s doing what and when. Cross-department clarity keeps the process moving and prevents small gaps from turning into big compliance problems.

Partner with Experts

If your clients don’t have the bandwidth internally, connect them with a trusted compliance partner. With a solution like Mitratech Mineral’s ACA Reporting Hub, employers can automate submissions, reduce risk, and breathe easier knowing their filings are handled correctly and on time.

Tips to Help Clients Meet ACA Reporting Deadlines 2025

The ACA reporting season doesn’t sneak up on those who plan ahead. A few practical steps can make the difference between a calm filing season and a frantic one. Here’s how to stay ahead:

• Start Early – Don’t wait until the calendar turns to February. The most time-consuming part of ACA reporting isn’t the forms—it’s tracking down and verifying employee data. Start early, confirm eligibility details, and double-check Social Security numbers before the rush hits.
• Use Technology to Your Advantage – Manual spreadsheets and email chains make mistakes almost inevitable. An ACA compliance platform, like Mitratech Mineral’s ACA Reporting Hub, helps automate form creation, catch errors before submission, and ensure reports go out on time.
• Stay Organized – Keep a clean record of every employee’s coverage and eligibility status. When your data is accurate and accessible, the reporting process becomes faster, smoother, and far less stressful.
• Communicate with Employees – Let employees know when to expect their Forms 1095-B or 1095-C and why those forms matter. Proactive communication not only builds trust but also reduces last-minute questions that can slow things down.
• Bring in the Experts When You Need Them – If ACA reporting still feels complex or time-consuming, don’t go it alone. A compliance partner can take the guesswork out of deadlines, formatting, and filings so you can focus on advising clients instead of troubleshooting submissions.

With the right preparation and tools, ACA reporting becomes less about panic and more about process, and that’s exactly where brokers add the most value.
