Form 1095-A vs. 1095-C: Key Differences (2026 Guide)

TL;DR

Form 1095-A comes from the Health Insurance Marketplace and is the only 1095 form that directly affects your federal tax return. Form 1095-C comes from large employers (50+ full-time employees) and is informational only. If your company offers an ICHRA, employees may receive both forms, which creates real confusion at tax time, especially around the Premium Tax Credit.

Tax season brings a pile of forms, and the 1095 series is one of the most confusing. You might get a Form 1095-A, a Form 1095-C, or both. They look similar, their names are nearly identical, and figuring out which one actually matters for your tax return is surprisingly hard.

This confusion intensifies for companies offering an Individual Coverage HRA (ICHRA), where employees shop for their own Marketplace plans but also receive employer-sponsored coverage documentation. Understanding the difference between form 1095-A vs 1095-C is essential for filing taxes correctly and staying compliant with the ACA.

Whether you’re an employee staring at two forms you didn’t expect, or an HR manager responsible for sending them, here’s everything you need to know. If your company is considering an ICHRA, you can explore employer solutions to see how the reporting process works in practice.

What Is Form 1095-A?

Form 1095-A, officially called the Health Insurance Marketplace Statement, goes to anyone who enrolled in a health insurance plan through Healthcare.gov or a state exchange during the tax year. The Marketplace itself sends this form, not your employer.

The form reports three critical pieces of information:

• Monthly premiums paid for your Marketplace plan
• Advance Premium Tax Credits (APTC) applied to reduce your monthly costs
• Second lowest cost Silver plan (SLCSP) premium for your area, which the IRS uses to calculate the credit you’re actually entitled to

This is the only 1095 form that directly affects your federal tax return. If you received a 1095-A, you must use it to complete IRS Form 8962, which reconciles the Premium Tax Credit. If you got more in advance credits than you qualified for, you’ll owe money back. If you got less, you’ll receive a refund.

The Marketplace must send Form 1095-A to enrollees by January 31 each year. If yours is late or contains errors, contact the Marketplace directly because your employer cannot fix it.

Bottom line: If you bought coverage through the Marketplace, expect a 1095-A. Don’t file your taxes without it.

What Is Form 1095-C?

Form 1095-C, formally titled Employer-Provided Health Insurance Offer and Coverage, comes from Applicable Large Employers (ALEs), meaning companies with 50 or more full-time employees. The employer sends this form to every full-time employee who was eligible for coverage during at least one month of the tax year.

The form reports:

• Whether the employer offered health coverage
• Which months coverage was available
• The employee’s share of the lowest-cost monthly premium for self-only coverage

The purpose of Form 1095-C is enforcement. It helps the IRS determine whether the employer satisfied its obligations under the ACA’s employer shared responsibility provisions. It also helps the IRS verify whether an employee was eligible for subsidized Marketplace coverage.

Here’s the key distinction in the form 1095-A vs 1095-C comparison: you do not need to enter 1095-C information on your tax return. Keep it with your records, but don’t attach it when you file. It’s informational only at the federal level.

For the 2025 tax year, employers must furnish 1095-C copies to employees by March 2, 2026. The IRS e-filing deadline is March 31, 2026. Businesses filing more than 10 returns of any type (including W-2s, 1099s, and 1095s) must file electronically, which means virtually every employer falls under this requirement.

Quick Comparison Table: Form 1095-A vs. 1095-C

This side-by-side view captures the core form 1095-A vs 1095-C differences. But there’s a third form in the mix that rounds out the picture.

Where Does Form 1095-B Fit In?

Form 1095-B (Health Coverage) is the third member of the 1095 family. It’s issued by insurance carriers, government programs like Medicaid and CHIP, and self-insured small employers with fewer than 50 full-time employees.

The form confirms that the recipient had minimum essential coverage during the year. Like the 1095-C, it is informational only and does not need to be entered on your federal tax return.

For small employers offering an ICHRA, Form 1095-B is the relevant filing. Because ICHRAs are classified as self-insured group health plans under ACA rules, a non-ALE employer must send a 1095-B to any employee who participated in the ICHRA for at least one month during the plan year.

This catches many small business owners off guard. As one compliance advisor noted, many employers assume the insurance carrier delivering the individual coverage handles the reporting. In reality, the employer has its own separate reporting obligation for the ICHRA.

The ICHRA Scenario: When You Receive Both Forms

This is where the form 1095-A vs 1095-C question gets genuinely complicated, and where most existing guides fall short.

When an employer offers an ICHRA, employees purchase their own individual health insurance, often through the Marketplace. That triggers a 1095-A from the exchange. At the same time, the employer must report the ICHRA offer on a 1095-C (if they’re an ALE) or 1095-B (if they’re under 50 employees).

The result: employees receive two forms covering the same tax year, for what feels like the same coverage.

What the 1095-A Looks Like for ICHRA Employees

If the ICHRA was considered affordable under IRS guidelines, the employee is not eligible for the Premium Tax Credit. The 1095-A in this case typically shows $0.00 in the APTC column. This is correct and expected, but it still triggers confusion at tax time.

The Premium Tax Credit Trap

This is a real and documented problem. Practitioners on TurboTax community forums report that employees with ICHRA coverage struggle when entering their 1095-A data into tax software. Even when the form shows $0 in credits, the software automatically prompts a PTC reconciliation calculation. One user wrote: “I received a 1095-A and have entered that information but my company has ICHRA and I cannot see where to put that in TurboTax to make sure the PTC is calculated correctly.”

The workarounds are clunky. Some users report entering placeholder values to force the software to accept the $0 credit amount. This is a design flaw in the software, not a mistake by the employee, but it creates real anxiety during filing season.

Anyone participating in a group health plan, including an ICHRA, is ineligible for the Premium Tax Credit. Even if your 1095-A shows up with premium data, do not claim a PTC you aren’t entitled to. The consequences can include owing money back to the IRS.

What Employees Should Do

1. Enter your 1095-A data into your tax return as prompted
2. Confirm $0 Premium Tax Credit if your ICHRA was affordable
3. Keep your 1095-C (or 1095-B) for your records but do not attach it to your return
4. If tax software gives you trouble, consult a tax professional familiar with ICHRA rules

What Employers Should Do

Communicate proactively before tax season. Send a simple notice explaining that employees will receive multiple 1095 forms and what to do with each. This one step prevents a flood of confused emails in February.

ALEs offering an ICHRA must use specific codes on Form 1095-C. Codes 1L through 1S in Part II, Line 14 indicate the ICHRA offer and correspond to different allowance amounts. Code 1G applies when the ICHRA is offered to part-time employees. The monthly ICHRA allowance amount goes in Line 15. Getting these codes wrong can trigger IRS penalty notices, so accuracy matters. For a deeper explanation of how these codes work, the guide on 1095-C Line 14 codes covers the specifics.

If you’re an employer navigating ICHRA reporting for the first time, a free consultation can help clarify your obligations before filing season arrives.

Filing Deadlines at a Glance (2025 Tax Year)

Missing these deadlines triggers penalties, so mark them clearly:

The e-filing threshold dropped to 10 returns in recent years. If your company files more than 10 combined information returns (W-2s, 1099s, and 1095s all count together), you must file electronically. Paper filing is essentially reserved for the smallest businesses.

State Mandates: Why 1095-B and 1095-C Still Matter

At the federal level, the individual mandate penalty has been $0 since 2019. That’s led some people to assume 1095-B and 1095-C forms are meaningless paperwork. They’re not.

California, Massachusetts, New Jersey, Rhode Island, Vermont, and the District of Columbia all enforce their own individual health insurance mandates. In these states, your 1095-B or 1095-C serves as proof that you had minimum essential coverage. Without it, you may owe a state penalty.

California’s penalty for 2026 is roughly $900 per uninsured adult and $450 per dependent child, unless you qualify for an exemption. That’s significant enough to make these “informational” forms very important for affected residents.

Employers with employees in mandate states need to distribute forms on time. California, for example, follows a January 31 distribution deadline for certain coverage documentation. If you operate across multiple states, staying compliant with both federal and state reporting requirements takes planning. The ICHRA compliance by state guide covers multi-location considerations.

Penalties for Employers Who Get This Wrong

The stakes for employers go beyond employee confusion. ACA penalties for ALEs are substantial and increasing.

For the 2026 calendar year:

• 4980H(a) penalty: $3,340 per full-time employee (minus a 30-employee reduction) if the employer fails to offer minimum essential coverage to at least 95% of full-time employees
• 4980H(b) penalty: $5,010 per affected full-time employee who receives subsidized Marketplace coverage because the employer’s offer was unaffordable or didn’t meet minimum value

The affordability threshold for 2026 is 9.96% of household income, up from 9.02% in 2025. This percentage determines whether an employee’s required contribution for self-only coverage is considered affordable under ACA rules. For ICHRA employers, this calculation uses the FPL safe harbor or other approved methods to determine if the allowance is sufficient.

Beyond the big mandate penalties, there are also information return penalties. Filing an incorrect 1095-C form can cost $340 per form. For an employer with 200 full-time employees, that adds up fast.

ICHRA-specific reporting errors are a particular risk area. Incorrect codes, wrong ZIP codes used in affordability calculations, or missing monthly allowance amounts on Line 15 can all create problems during an IRS review.

A Simple Decision Tree

Not sure which form applies to you? Walk through these questions:

Did you buy health insurance through the Marketplace (Healthcare.gov or a state exchange)?
Yes → You’ll receive a 1095-A. Use it to file Form 8962.

Does your employer have 50 or more full-time employees?
Yes → You’ll receive a 1095-C. Keep it for your records.

Does your employer offer an ICHRA?
Yes → You may receive both a 1095-A (from the Marketplace) and a 1095-C or 1095-B (from your employer). Enter the 1095-A data on your return, confirm $0 PTC if the ICHRA was affordable, and file the rest for safekeeping.

Are you a small employer (<50 FTE) offering an ICHRA?
Yes → You must file Form 1095-B for participating employees.

Understanding form 1095-A vs 1095-C is really about understanding the source of your coverage and who’s responsible for reporting it. The Marketplace reports what you bought. The employer reports what they offered. When both are in play, both forms show up.

Frequently Asked Questions

Can I receive both a 1095-A and a 1095-C?

Yes. This is common when an employer offers an ICHRA and employees purchase Marketplace coverage. The Marketplace sends the 1095-A, and the employer (if an ALE) sends the 1095-C. Both forms cover the same tax year but serve different purposes.

Do I attach Form 1095-C to my tax return?

No. Form 1095-C is informational only at the federal level. Keep it with your tax records but do not send it to the IRS with your return. The same applies to Form 1095-B.

What if my 1095-A has errors?

Contact the Marketplace that issued the form. Your employer cannot correct a 1095-A. Common errors include wrong premium amounts, incorrect months of coverage, or a missing SLCSP figure. Wait for the corrected form before filing your tax return.

Does ICHRA coverage count as minimum essential coverage?

Yes. ICHRAs are classified as self-insured group health plans under ACA rules and satisfy the minimum essential coverage requirement. This is true regardless of whether the employer is an ALE or a small business.

I’m a small employer with fewer than 50 employees. Which form do I file for ICHRA?

Small employers offering an ICHRA file Form 1095-B for any employee who participated in the arrangement for at least one month. You do not file Form 1095-C because that obligation applies only to ALEs.

My tax software is asking me to claim a Premium Tax Credit, but I have ICHRA coverage. What do I do?

If your ICHRA was affordable, you are not eligible for the PTC. Your 1095-A should show $0 in the APTC column. If your tax software auto-calculates a credit, you may need to manually override it or consult a tax professional. This is a known issue in popular tax software that practitioners have flagged in online forums.

What happens if my employer misses the 1095-C deadline?

The IRS can impose penalties of $340 per incorrect or late form. For large employers, these penalties can reach hundreds of thousands of dollars. Beyond monetary penalties, late or inaccurate filing can trigger IRS scrutiny of the employer’s ACA compliance overall.

Why did my 1095-A arrive in January but my 1095-C didn’t come until March?

Different deadlines. The Marketplace must send Form 1095-A by January 31. Employers have until March 2 (for the 2025 tax year) to furnish Form 1095-C to employees. If you’re waiting on a 1095-A to file your taxes, don’t delay. If you’re waiting on a 1095-C, you can file without it since it doesn’t affect your return.

Managing form 1095-A vs 1095-C compliance is one of the less glamorous parts of offering health benefits, but getting it right protects both the employer and the employee. For companies offering an ICHRA, the reporting requirements add a layer of complexity that generic payroll tools don’t always handle well.
