Understanding 1095-C FMLA Reporting: A Comprehensive Guide for Employers

Introduction: The Challenge of ACA Reporting During FMLA Leave

One of the most challenging aspects of Affordable Care Act (ACA) compliance is understanding how to properly complete 1095-C FMLA reporting when employees take leave under the Family and Medical Leave Act. For HR professionals, benefits administrators, and employers managing ACA compliance, the intersection of FMLA leave and Form 1095-C reporting creates unique complexities that require careful attention to detail and a thorough understanding of both federal programs.

The Family and Medical Leave Act provides eligible employees with up to 12 weeks of job-protected, unpaid leave annually for qualifying reasons, including the birth or adoption of a child, serious health conditions, and caring for family members. During this time, employers are generally required to maintain group health insurance coverage under the same terms as if the employee had continued working. But how does this requirement translate to Form 1095-C reporting? What codes should you use? How do you handle situations where employees do not pay their premiums during leave?

Getting 1095-C FMLA reporting wrong can have serious consequences. The IRS imposes penalties of up to $330 per form for incorrect or late filings, with potential penalties reaching millions of dollars for large employers. Beyond financial penalties, inaccurate reporting can trigger Letter 226-J employer shared responsibility payment assessments if the IRS believes you failed to offer adequate coverage. Furthermore, employees may face confusion about their coverage status when reconciling their tax returns.

This guide addresses every aspect of 1095-C FMLA reporting, from fundamental concepts to specific scenarios and correct codes. Whether you handle a few FMLA cases annually or manage hundreds of employees on various types of leave, this guide will equip you with the knowledge to handle 1095-C FMLA situations confidently.

Foundational Concepts: FMLA and ACA Reporting Basics

Understanding FMLA Leave and Employer Obligations

Before diving into 1095-C FMLA reporting specifics, it is essential to understand what FMLA requires of employers regarding health insurance. The Family and Medical Leave Act mandates that covered employers must maintain group health insurance coverage for employees on FMLA leave on the same terms as if the employee had continued to work. This means the employer must continue to offer coverage and pay the employer portion of premiums during the FMLA period.

Key FMLA provisions affecting health coverage:

  • Continuation of coverage: Employers must maintain the same level of coverage during FMLA leave as was provided before the leave began
  • Premium obligations: Employers continue paying their share of premiums; employees remain responsible for their share
  • Premium payment methods: Employers may require employees to pay their share through payroll deduction (upon return), pay-as-you-go, or catch-up payments
  • Coverage termination rights: Employers may terminate coverage if an employee's premium payment is more than 30 days late, but must provide written notice first
  • Reinstatement: If coverage lapses due to non-payment, it must be restored immediately upon return from FMLA leave without new waiting periods or eligibility requirements

These FMLA requirements directly impact how employers complete 1095-C FMLA forms. The continued offer of coverage during leave means that Line 14 typically continues to reflect an offer of coverage, even when the employee is not actively working.

Full-Time Employee Status During FMLA Leave

A critical question for 1095-C FMLA reporting is whether an employee on FMLA leave remains classified as full-time for ACA purposes. The answer depends on which measurement method your organization uses to determine full-time status.

Monthly Measurement Method:

Under the monthly measurement method, an employee's full-time status is determined each month based on whether they averaged 30 or more hours of service per week (or 130 hours for the month). During FMLA leave, an employee is generally not credited with hours of service (unless paid). This could result in the employee not being considered full-time for the months on unpaid FMLA leave.

However, the IRS regulations provide that employers using the monthly measurement method may treat employees on FMLA leave as full-time for any month in which they would have worked full-time hours but for the leave. Most employers elect this treatment to maintain consistent reporting and avoid potential penalty exposure.

Look-Back Measurement Method:

For employers using the look-back measurement method, the full-time status determination is made during a measurement period and then locked in for the subsequent stability period. If an employee was determined to be full-time during the standard or initial measurement period, they remain full-time throughout the entire stability period—regardless of any hours reductions, including FMLA leave.

This means for most employers using the look-back method, employees on FMLA leave continue to be treated as full-time for 1095-C FMLA reporting purposes throughout their stability period. The leave does not affect their previously determined full-time status.

Who Must Receive Form 1095-C During FMLA

Under ACA reporting requirements, Applicable Large Employers (ALEs) must furnish Form 1095-C to every employee who was a full-time employee for any month during the tax year. This includes employees who were on FMLA leave during part or all of the year.

An employee on FMLA leave for the entire year would still receive a 1095-C FMLA form if they were classified as full-time for any month. The form documents the offers of coverage made during their leave period and any actual enrollment in coverage (for self-insured plans). There is no exception to the 1095-C furnishing requirement for employees on FMLA leave.

Comprehensive Analysis: Line 14 Codes for 1095-C FMLA Scenarios

Understanding Line 14 During FMLA Leave

Line 14 of Form 1095-C reports the type of coverage offered to the employee for each month. For 1095-C FMLA situations, the key question is: Did the employer continue to offer coverage during the FMLA leave period? Under FMLA requirements, the answer is almost always yes—employers must maintain coverage during qualifying FMLA leave.

Because FMLA requires employers to maintain coverage on the same terms, the Line 14 code during FMLA leave should typically reflect the same offer that applied before the leave began. If you offered minimum value coverage to the employee and dependents before leave, you continue to report that same offer during the FMLA period.

Common Line 14 codes for 1095-C FMLA situations:

Code Description When to Use During FMLA
1A Qualifying offer to employee, spouse, and dependents If this was the pre-FMLA offer and coverage continued during leave
1B Minimum value offered to employee only If employee-only coverage continued during leave
1C Minimum value to employee, MEC to dependents If this was the pre-FMLA offer and coverage continued during leave
1E Minimum value offered to employee, spouse, and dependents Most common code when full coverage continued during FMLA
1H No offer of coverage Rarely appropriate during FMLA—only if coverage was properly terminated due to non-payment

When Coverage Offer Changes During FMLA

In most 1095-C FMLA situations, the Line 14 code remains constant throughout the leave because FMLA requires maintenance of the same coverage. However, there are limited circumstances where the offer may change:

Scenario 1: Coverage termination due to non-payment

If an employee fails to pay their required premium contribution during FMLA leave and the employer follows proper procedures to terminate coverage (including the required 15-day notice), coverage may lapse. In this case:

  • For months where coverage was offered and available, use the applicable 1A-1E code
  • For months where coverage was terminated due to non-payment, technically an offer may still exist (the employee could restore coverage by paying), but some employers use code 1H if coverage actually terminated
  • The safer approach is to continue reporting the offer (1A-1E) since the coverage would have been available had the employee paid

Scenario 2: Annual enrollment during FMLA

If your organization's annual open enrollment occurs while an employee is on FMLA leave, the employee has the right to make enrollment changes. The Line 14 code may change based on their new elections, but FMLA still requires that the same coverage levels be available as would be available to active employees.

Scenario 3: Plan changes affecting all employees

If your health plan offerings change for all employees (such as adding or removing dependent coverage options), those changes also apply to employees on FMLA leave. The Line 14 code would reflect the new coverage offer.

Special Considerations for Line 14

When completing 1095-C FMLA forms, pay attention to these special considerations:

  • Consistency with pre-leave coding: Your FMLA month codes should generally match your pre-leave codes unless a legitimate coverage change occurred
  • Documentation: Maintain records of the coverage offer during FMLA, including any notices sent to employees about premium payments
  • Intermittent FMLA: For employees taking intermittent FMLA leave, the coverage offer typically remains unchanged—report the same Line 14 code throughout
  • FMLA plus other leave: If an employee's FMLA exhausts and they continue on employer-provided leave, the coverage terms may change; adjust Line 14 accordingly

Line 15 Reporting for Employees on FMLA Leave

Employee Share of Premium During FMLA

Line 15 reports the employee's monthly share of the lowest-cost self-only minimum value coverage offered. For 1095-C FMLA reporting, this amount typically does not change during leave. FMLA requires that coverage be maintained on the same terms, which means the employee cost-sharing arrangements remain the same.

Key points for Line 15 during FMLA:

  • Same premium amount: Report the same employee premium share that applied before FMLA leave began
  • Affordability calculations: The employee's required contribution continues to be relevant for affordability determinations, even during unpaid leave
  • Leave blank when appropriate: If Line 14 is coded 1A (qualifying offer), you may leave Line 15 blank because the qualifying offer indicator already establishes affordability
  • No change for payment method: Whether the employee pays premiums via payroll deduction, direct payment, or catch-up after returning does not affect the Line 15 amount

Premium Amount Scenarios

Consider these 1095-C FMLA scenarios for Line 15:

Example 1: Standard FMLA with continued premium payment

Sarah takes 12 weeks of FMLA leave for the birth of her child. Her monthly premium contribution for self-only coverage is $250. She continues paying this amount through direct billing during her leave. Line 15 should show $250.00 for all months, including the FMLA months.

Example 2: FMLA with premium catch-up

Michael takes 8 weeks of FMLA leave. Rather than paying premiums during leave, he arranges to have the premiums deducted from his paychecks upon return. His monthly contribution is $200. Line 15 should still show $200.00 for all months, including the FMLA period. The payment method does not change the required contribution amount.

Example 3: Premium change during FMLA (annual enrollment)

Jennifer is on FMLA leave from September through November. During October open enrollment, she changes her coverage tier. Before October, her monthly contribution was $175. After her enrollment change, it becomes $225. Line 15 would show $175.00 for January through September and $225.00 for October through December.

Line 16 Codes for 1095-C FMLA Situations

Understanding Line 16 During FMLA Leave

Line 16 of Form 1095-C reports applicable safe harbors and other relief provisions. For 1095-C FMLA situations, selecting the correct Line 16 code is crucial for demonstrating compliance with the employer shared responsibility provisions and avoiding penalties.

Most common Line 16 codes for 1095-C FMLA scenarios:

Code Description When to Use During FMLA
2A Employee not employed during the month NOT appropriate for FMLA—employee is still employed
2B Not a full-time employee Rarely appropriate if using look-back; may apply under monthly method if not treating as full-time
2C Employee enrolled in coverage Use when employee maintained enrollment during FMLA leave
2D Employee in limited non-assessment period May apply for new hires who go on FMLA during waiting period
2F W-2 safe harbor Can use if employee enrolled OR if coverage was affordable based on W-2 wages
2G Federal poverty line safe harbor Can use if employee enrolled OR if coverage was affordable based on FPL
2H Rate of pay safe harbor Can use if employee enrolled OR if coverage was affordable based on rate of pay

Recommended Line 16 Approach for FMLA

For most 1095-C FMLA situations, the recommended approach is:

If the employee remained enrolled in coverage during FMLA:

  • Use code 2C (employee enrolled in coverage) for any month the employee was enrolled
  • This is the strongest protection because it demonstrates actual enrollment, not just an offer
  • Even if the employee was behind on premium payments but coverage was maintained, use 2C

If the employee was offered but not enrolled in coverage during FMLA:

  • Use the applicable safe harbor code (2F, 2G, or 2H) if the coverage was affordable
  • The rate of pay safe harbor (2H) may be particularly useful during FMLA because it uses the employee's rate of pay rather than actual wages earned
  • The W-2 safe harbor (2F) may result in a low W-2 amount for employees on unpaid leave, potentially making coverage appear unaffordable

Special Line 16 Scenario: Coverage Lapse During FMLA

If an employee's coverage lapses during FMLA due to non-payment of premiums, the 1095-C FMLA coding becomes more complex:

  • For months where coverage was in effect, use code 2C
  • For months where coverage lapsed but an offer was still available, consider using a safe harbor code if applicable
  • For months where no offer was made (rare, but possible if coverage was terminated and not offered again), leave Line 16 blank

However, remember that FMLA requires immediate reinstatement of coverage upon return from leave. If coverage lapsed during FMLA, it must be restored without waiting periods when the employee returns.

Part III Reporting for Self-Insured Plans During FMLA

When to Complete Part III

Part III of Form 1095-C applies only to employers with self-insured health plans. For 1095-C FMLA situations with self-insured coverage, Part III documents the months during which individuals were actually enrolled in coverage.

Part III completion for FMLA situations:

  • Employee maintained coverage: Check the boxes for each month the employee was enrolled in the self-insured plan, including FMLA months
  • Dependents maintained coverage: List each covered dependent with their SSN (or date of birth) and check the months of coverage
  • Coverage lapsed during FMLA: Only check boxes for months when coverage was actually in effect
  • Retroactive reinstatement: If coverage was reinstated retroactively upon return from FMLA, check the boxes for all months including the retroactive period

COBRA Considerations During FMLA

FMLA leave is distinct from COBRA coverage, but they can interact in 1095-C FMLA reporting:

  • FMLA coverage is not COBRA: Coverage maintained during FMLA leave is regular employer coverage, not COBRA continuation
  • COBRA may apply after FMLA: If an employee does not return from FMLA leave and employment terminates, a COBRA qualifying event occurs
  • Reporting distinction: During FMLA, report as regular coverage. If COBRA begins after FMLA/termination, that is a different reporting scenario

Step-by-Step Guidance: Completing 1095-C for FMLA Scenarios

Scenario 1: Standard 12-Week FMLA Leave with Continued Enrollment

Jennifer is a full-time employee who takes FMLA leave from March 1 through May 24. She remains enrolled in the employer's self-insured health plan throughout her leave, paying her premiums via direct billing. The employer offers minimum value coverage to employees, spouses, and dependents.

Step-by-step 1095-C completion:

Part I: Complete employee and employer information as normal

Part II, Line 14:

  • All 12 Months: 1E (minimum value offered to employee, spouse, and dependents)
  • No month-by-month variation needed since the offer remained constant

Part II, Line 15:

  • All 12 Months: Enter Jennifer's monthly share of the lowest-cost self-only coverage (e.g., $200.00)

Part II, Line 16:

  • All 12 Months: 2C (employee enrolled in coverage)

Part III:

  • List Jennifer and check all 12 months
  • List any covered dependents and check all 12 months

Scenario 2: FMLA with Coverage Termination Due to Non-Payment

Robert takes FMLA leave starting June 1. He fails to pay his premium share for June and July despite notice. The employer terminates his coverage effective July 15 following proper procedures. Robert returns from FMLA August 15 and coverage is reinstated immediately.

Step-by-step 1095-C completion:

Part II, Line 14:

Month Code Explanation
January - June 1E Full offer in effect
July 1E Coverage offered (coverage partially in effect until mid-month)
August - December 1E Full offer in effect (coverage reinstated mid-August)

Part II, Line 16:

Month Code Explanation
January - June 2C Employee enrolled in coverage
July 2C or 2H Coverage partially in effect; could argue enrolled or use safe harbor
August - December 2C Coverage reinstated

Part III:

  • Check January through mid-July (coverage in effect)
  • Do not check late July if coverage actually terminated
  • Check mid-August through December (coverage reinstated)

Scenario 3: Intermittent FMLA Throughout the Year

Lisa takes intermittent FMLA leave totaling 8 weeks spread across the year for her own serious health condition. She works reduced hours on some weeks and takes full weeks off on others. Her coverage continues throughout.

Step-by-step 1095-C completion:

Part II, Line 14:

  • All 12 Months: 1E (or applicable offer code)
  • Intermittent FMLA does not change the coverage offer

Part II, Line 15:

  • All 12 Months: Enter Lisa's monthly share (unchanged by intermittent leave)

Part II, Line 16:

  • All 12 Months: 2C (employee enrolled in coverage throughout)

Part III:

  • Check all 12 months (Lisa was covered throughout despite reduced/intermittent hours)

Common Mistakes and How to Avoid Them

Mistake 1: Using Code 2A for FMLA Months

One of the most common errors in 1095-C FMLA reporting is using Line 16 code 2A (employee not employed during the month) for FMLA months. This is incorrect because employees on FMLA leave are still employed—they have job-protected leave, not a termination of employment.

Correct approach: Use code 2C if the employee is enrolled in coverage, or an applicable safe harbor code if they declined coverage. Never use 2A for FMLA periods.

Mistake 2: Changing Line 14 to 1H During FMLA

Some employers mistakenly change Line 14 to code 1H (no offer of coverage) during FMLA leave, thinking that because the employee is not working, there is no offer. This violates both FMLA requirements (which mandate continuation of coverage) and accurate 1095-C FMLA reporting.

Correct approach: Continue reporting the same Line 14 offer code that applied before FMLA leave. Under FMLA, the coverage offer must be maintained.

Mistake 3: Using W-2 Safe Harbor for Extended Unpaid FMLA

The W-2 safe harbor (code 2F) bases affordability on W-2 Box 1 wages. For employees on extended unpaid FMLA leave, their W-2 wages may be significantly reduced, potentially causing coverage to appear unaffordable even when the premium amount is unchanged.

Correct approach: For employees on FMLA, consider using the rate of pay safe harbor (2H) instead, which is based on the employee's rate of pay rather than actual wages earned. Alternatively, if the employee is enrolled, simply use code 2C.

Mistake 4: Failing to Report FMLA Employees on Part III

For self-insured plans, some employers forget to include employees on FMLA leave in Part III. If the employee remained enrolled in coverage during FMLA, they must be listed on Part III with the appropriate months checked.

Correct approach: List any employee who were enrolled in your self-insured plan during FMLA leave, checking all months of coverage.

Deadlines and Penalties for 1095-C FMLA Reporting

Filing and Furnishing Deadlines

Form 1095-C, including 1095-C FMLA forms for employees on leave, must be filed with the IRS and furnished to employees by the standard ACA reporting deadlines:

Deadline Type Tax Year 2025 Deadline Notes
Furnish to employees March 3, 2026 Applies to all employees including those on FMLA
File with IRS (electronic) March 31, 2026 Electronic filing required for 10+ forms
File with IRS (paper) February 28, 2026 Only for employers filing fewer than 10 forms

For employees who were on FMLA leave and have since returned, ensure you have their current address for mailing their 1095-C FMLA form. For employees who did not return from FMLA leave, use the last known address or verify if they provided an updated address before separation.

Penalties for Incorrect Reporting

Inaccurate 1095-C FMLA reporting can result in significant penalties:

  • $60 per form if corrected within 30 days of the required filing date
  • $130 per form if corrected after 30 days but by August 1
  • $330 per form if not corrected by August 1
  • $660 per form (no maximum) for intentional disregard

Additionally, incorrect 1095-C FMLA coding could lead to erroneous employer shared responsibility penalty assessments. If your forms incorrectly suggest you failed to offer coverage during FMLA months, the IRS may issue Letter 226-J proposing penalties that you will need to contest.

How to Correct 1095-C FMLA Errors

If you discover errors on previously filed 1095-C FMLA forms, corrected forms should be filed promptly:

  • Check the "CORRECTED" box at the top of the form
  • Enter all information correctly (not just the corrected fields)
  • Furnish a corrected copy to the employee
  • File corrected forms through the IRS AIR system

Prompt correction reduces penalty exposure and ensures employees have accurate information about their coverage.

Frequently Asked Questions About 1095-C FMLA Reporting

Do employees on FMLA leave receive Form 1095-C?

Yes, employees on FMLA leave must receive Form 1095-C if they were classified as full-time for any month during the tax year. The form documents the coverage offered and enrollment during leave.

What Line 14 code should I use for FMLA months?

Use the same Line 14 code that applied before leave began. Since FMLA requires employers to maintain coverage on the same terms, the offer code does not change during leave.

Should I use code 2A for months an employee was on FMLA?

No. Code 2A indicates the employee was not employed. Employees on FMLA remain employed with job-protected leave. Use code 2C if enrolled, or a safe harbor code (2F, 2G, or 2H) if not enrolled.

How do I report FMLA on 1095-C if the employee did not pay premiums?

If coverage was maintained despite non-payment, report normal enrollment. If coverage terminated due to non-payment, check only months coverage was in effect on Part III. FMLA requires immediate reinstatement upon return.

Is FMLA coverage the same as COBRA coverage for 1095-C purposes?

No. Coverage during FMLA is regular employer-sponsored coverage, not COBRA. Report it as regular coverage. COBRA only applies if employment terminates after FMLA.

How does intermittent FMLA affect 1095-C reporting?

Intermittent FMLA has minimal impact. The employee remains employed and offered coverage throughout. Report the same Line 14 code for all months, and use code 2C if enrolled.

What if an employee goes on FMLA during their initial measurement period?

FMLA leave during the measurement period could affect full-time determination. Some employers credit hypothetical hours for FMLA to avoid this outcome. Consult your organization's ACA compliance procedures.

Do I report FMLA leave months on Part III of Form 1095-C?

For self-insured plans, Part III reflects actual enrollment. Check months when the employee was enrolled. If coverage lapsed, only check months coverage was in effect.

Can I use the Federal Poverty Line safe harbor during FMLA?

Yes, code 2G can be used if coverage met the FPL affordability threshold. However, if the employee was enrolled, code 2C is typically the better choice.

How do state FMLA laws affect 1095-C reporting?

The same principles apply for state FMLA-type leave. Report the coverage offer maintained during leave. State ACA filing requirements (California, New Jersey, D.C.) also apply.

What happens if I make a mistake on a 1095-C for an FMLA employee?

File a corrected form promptly. Check the "CORRECTED" box, complete all fields accurately, furnish a copy to the employee, and submit to the IRS. See our guide on how to correct ACA forms.

Does FMLA affect an employee's status as a full-time employee for ACA purposes?

Under the look-back method, full-time status is locked in for the stability period. FMLA during stability period does not change status. Under monthly measurement, employers may treat FMLA employees as full-time.
