If your dependents are not listed on your 1095-C, the reason is almost always that your employer buys coverage from an outside insurance company rather than paying claims itself. In that setup, the insurer reports dependent enrollment on a separate Form 1095-B, and Part III of your 1095-C is meant to stay blank. So a form that shows no spouse or children is usually correct, not broken.
Why Part III Is Blank on a Fully-Insured Plan
The whole question turns on who bears the financial risk of the health plan. In a fully-insured arrangement, your employer pays premiums to an insurance company, and that insurer pays the claims. Because the insurer administers the plan and knows exactly who is enrolled, the insurer is the one that reports covered individuals to the IRS.
That reporting happens on Form 1095-B, which lists the name, Social Security number, and months of coverage for every covered person, including your spouse and children.1Internal Revenue Service. Form 1095-B – Health Coverage Your employer’s job on the 1095-C is limited to Part II, which documents the offer of coverage it made to you as a full-time employee. Part III stays blank because the insurer has already reported the dependent details somewhere else.2Internal Revenue Service. Instructions for Forms 1094-B and 1095-B
If this is your situation, you should end up with two forms in hand: a 1095-C from your employer, and a 1095-B from the insurance carrier. The 1095-B is the one that names your dependents.
When Dependents Should Appear
Self-insured plans work differently. The employer pays claims out of its own funds instead of buying coverage from an insurer, so there is no outside carrier to file a 1095-B. The employer puts everything on one 1095-C and has to complete Part III with the enrollment details for every covered person.3Internal Revenue Service. Instructions for Forms 1094-C and 1095-C (2025)
Part III requires the full name, Social Security number (or date of birth if no SSN is available), and the specific months of coverage for you and each enrolled dependent. If your employer runs a self-insured plan and your covered spouse or children are missing from Part III, that is a genuine error that needs correcting.3Internal Revenue Service.

How to Tell Which Type of Plan You Have
Since everything hinges on this one distinction, it helps to confirm which kind of plan your employer sponsors. Most people never think about it, and employers don’t always make it obvious. A few practical ways to check:
- Look at your Summary Plan Description. Your employer is required to provide this document, and it usually states whether the plan is self-funded or fully insured.
- Check your insurance card. If a major insurance company appears as both the insurer and the claims administrator, the plan is likely fully insured. If the card says “administered by” an insurer but the employer funds the coverage, it may be self-insured.
- Ask HR or benefits directly. They can confirm the funding arrangement in one email.
- See whether a 1095-B arrived. If you received one from an insurance carrier that lists your dependents, your plan is almost certainly fully insured and the blank Part III on your 1095-C is correct.
What to Do If You Have a Self-Insured Plan and Dependents Are Missing
If you’ve confirmed the plan is self-insured and covered dependents still aren’t in Part III, contact HR or your benefits office and ask them to review the form. The employer is responsible for issuing a corrected 1095-C to both you and the IRS, and corrected forms have to be clearly marked so they can be distinguished from the original.3Internal Revenue Service. Instructions for Forms 1094-C and 1095-C (2025)
Keep both the original and the corrected version with your tax records. If the problem is a wrong Social Security number rather than a missing person, the employer should verify the information against your personnel records and may ask you to confirm the correct number.4Internal Revenue Service.

The concern with a self-insured plan is that the IRS cross-references Part III to verify that each person listed had minimum essential coverage. If your dependents were enrolled but aren’t listed, the IRS has no record of their coverage from this source, which could prompt a notice or require you to document coverage through other records.
Does This Affect Your Taxes?
By itself, a blank Part III does not change what you owe or what you can claim. Your tax situation is driven by the codes in Part II of the 1095-C, not by the dependent listing. The IRS uses the Line 15 dollar amount to test whether the coverage your employer offered was affordable. For plan years beginning in 2026, coverage counts as affordable if the lowest-cost employee-only plan does not exceed 9.96% of your household income.5Internal Revenue Service. Rev. Proc. 2025-25 If the offer meets that threshold, you generally cannot claim the Premium Tax Credit for Marketplace coverage.
Whether your dependents appear in Part III has no bearing on that calculation for fully-insured plans, because the 1095-B already documents their enrollment.
There is one dependent-related wrinkle worth knowing about. Even when the employee-only premium is affordable, the cost to cover your whole family can be much higher. Under rules finalized in 2022, your spouse and dependents can qualify for Marketplace premium tax credits on their own if the family coverage premium exceeds the affordability threshold relative to household income. This is often called the fix for the “family glitch.” Your 1095-C won’t show the family premium directly, but the Line 14 codes confirm whether coverage was offered to your dependents, which is where the analysis starts.6Internal Revenue Service.

One last boundary: you do not attach either the 1095-C or the 1095-B to your federal return. Both forms are for your records. The IRS receives its copies directly from your employer and the insurance carrier.7Internal Revenue Service. Questions and Answers About Health Care Information Forms for Individuals
