Understanding 1095-C Code 1H: The Complete Guide to No Offer of Coverage

Introduction: What Is 1095-C Code 1H and Why Does It Matter?

If you are responsible for ACA compliance at your organization, understanding when to use 1095-C Code 1H on Form 1095-C is absolutely essential for accurate reporting. Code 1H is one of the most consequential Line 14 codes because it directly indicates that no health coverage was offered to a full-time employee during a particular month. When you use Code 1H for a full-time employee, you are signaling to the IRS that you potentially did not meet the employer mandate requirement to offer coverage to that employee. This makes Code 1H fundamentally different from other Line 14 codes that describe various types of coverage offers.

The significance of correctly using 1095-C Code 1H cannot be overstated. Unlike codes such as Code 1A or Code 1E that indicate coverage was offered, Code 1H tells the IRS that coverage was NOT offered. For full-time employees, this creates potential exposure to the Penalty A (4980H(a)) assessment if your organization fails to offer coverage to at least 95% of full-time employees. If the uncovered employee also receives a Marketplace premium tax credit, your organization may face a Letter 226-J proposing significant penalties. Getting this coding wrong can either expose you to unwarranted penalty risk or cause you to miss legitimate penalty-protection codes.

This guide covers everything about 1095-C Code 1H: when to use it, how it interacts with Line 16 codes, penalty implications, common mistakes, and real-world examples. Whether you are a small ALE or a large enterprise, this guide ensures you correctly apply Code 1H.

What Is 1095-C Code 1H: Definition and Requirements

Definition of Code 1H

1095-C Code 1H is used on Line 14 of Form 1095-C to indicate that an Applicable Large Employer (ALE) did NOT offer health coverage to an individual for a particular month. The official IRS description for Code 1H is simply: "No offer of coverage." This code represents the absence of any health coverage offer, not even minimum essential coverage (MEC) that does not meet minimum value requirements. When you enter Code 1H on Line 14 for any month, you are reporting that no coverage of any kind was made available to that individual during that month.

It is critical to understand that 1095-C Code 1H is a factual statement about whether coverage was offered, not a judgment about whether it should have been offered. The code is appropriate in many legitimate situations where coverage was not offered, including months before an employee's hire date, months after termination, months during a legitimate waiting period, and months for individuals who are not full-time employees. However, using Code 1H for full-time employees without a legitimate excuse documented on Line 16 creates penalty exposure.

When Is Code 1H Appropriate?

The most important factor in determining when to use 1095-C Code 1H is whether the individual was a full-time employee during the month in question and whether any legitimate reason existed for not offering coverage. Code 1H is appropriate in the following situations:

  • Employee not yet hired: For months before the employee's start date, Code 1H is appropriate on Line 14 with Code 2A on Line 16 (Employee not employed during the month)
  • Employee terminated: For months after termination, Code 1H is appropriate with Code 2A on Line 16
  • Initial measurement period: For new variable-hour or seasonal employees during their initial measurement period, Code 1H may be appropriate with Code 2D on Line 16
  • Employee not full-time: For employees who did not work full-time during the month, Code 1H may be appropriate with Code 2B on Line 16
  • Non-full-time in self-insured plan: For non-full-time employees covered under a self-insured plan, Code 1G should be used instead of Code 1H
  • No excuse available: When a full-time employee was not offered coverage and no legitimate excuse applies, Code 1H is used with no Line 16 code, which may trigger penalty exposure

Code 1H vs. Other Line 14 Codes

1095-C Code 1H is fundamentally different from all other Line 14 codes because it indicates NO coverage was offered. All other Line 14 codes (1A through 1G) describe various types of coverage that WERE offered. Understanding this distinction is crucial:

Code Coverage Offered? Description
1A Yes Qualifying Offer (MV to employee, MEC to spouse/dependents, affordable)
1B Yes MV to employee only
1C Yes MV to employee, MEC to dependents only
1D Yes MV to employee, MEC to spouse only
1E Yes MV to employee, MEC to spouse and dependents
1F Yes MEC but not MV (coverage offered but below 60% actuarial value)
1G Yes MEC to non-full-time employee in self-insured plan
1H No No offer of coverage

As the table shows, 1095-C Code 1H stands alone as the only code indicating no coverage was offered. This makes Line 16 particularly important when using Code 1H because Line 16 codes explain why no coverage was offered and whether a legitimate excuse exists that protects the employer from penalties.

Line 16 Codes: Critical Companions to Code 1H

Why Line 16 Matters When Using Code 1H

When you use 1095-C Code 1H on Line 14, the Line 16 code becomes critical for determining whether you have penalty protection. Line 16 codes explain the circumstances surrounding the lack of a coverage offer. Some Line 16 codes provide complete penalty protection (like 2A for not employed), while others provide partial protection or no protection at all. Failing to use the appropriate Line 16 code when Code 1H applies can result in unnecessary penalty assessments.

Line 16 Codes Commonly Used with Code 1H

Line 16 Code Description When to Use with Code 1H Penalty Protection
2A Employee not employed during the month Months before hire date or after termination Full protection
2B Employee not a full-time employee Months when employee did not average 30+ hours/week Full protection
2D Employee in a limited non-assessment period (waiting period, initial measurement period) During waiting periods or measurement periods for new variable-hour employees Full protection
2I Reserved (formerly non-calendar year transition relief) No longer applicable for current tax years N/A
None No Line 16 code entered When no legitimate excuse exists for not offering coverage No protection - potential penalty exposure

Understanding the Penalty-Protective Codes

When using 1095-C Code 1H, the following Line 16 codes provide protection from employer shared responsibility penalties:

Code 2A (Not Employed): If the employee was not employed during the month (either not yet hired or already terminated), Code 2A applies. Always use Code 2A with Code 1H for months outside the employment period.

Code 2B (Not Full-Time): The employer mandate only requires coverage offers to full-time employees (those averaging 30 or more hours per week). If an employee was not full-time during a month, Code 2B provides protection.

Code 2D (Limited Non-Assessment Period): This code covers legitimate periods during which an ALE is not required to offer coverage, including the initial waiting period (up to 90 days), the initial measurement period for variable-hour employees, and the administrative period following an initial measurement period.

Penalty Implications of Using Code 1H

Understanding Penalty A and Penalty B

The Penalty A assessment applies when an ALE fails to offer minimum essential coverage to at least 95% of its full-time employees during any calendar month, and at least one full-time employee receives a Marketplace premium tax credit. Using 1095-C Code 1H for full-time employees without a penalty-protective Line 16 code counts toward your non-offer percentage. Penalty A is approximately $2,970 per full-time employee (minus 30) for 2025.

Penalty B applies when an ALE offers coverage to at least 95% of full-time employees but an individual employee was not offered coverage (or received unaffordable/non-MV coverage) and received a Marketplace premium tax credit. Penalty B is approximately $4,460 per affected employee for 2025.

How Line 16 Codes Eliminate Penalty Risk

The penalty-protective Line 16 codes (2A, 2B, 2D) provide "limited non-assessment period" protection. When these codes apply, the IRS will not assess penalties even if no coverage was offered. However, if you use 1095-C Code 1H and leave Line 16 blank, you have no penalty protection, and the IRS will consider that employee as "not offered coverage" for penalty calculation purposes.

Real-World Scenarios: When to Use 1095-C Code 1H

Scenario 1: New Hire During the Waiting Period

Situation: Acme Corporation hires John Smith on March 15, 2025. John is a full-time salaried employee. Acme has a 60-day waiting period before employees are eligible for health coverage. John becomes eligible for coverage on May 15 and enrolls effective June 1.

Correct coding:

  • Line 14: Jan-Feb = 1H, March = 1H, April = 1H, May = 1H, June-December = 1E (or appropriate offer code)
  • Line 15: Jan-May = blank, June-December = employee premium amount
  • Line 16: Jan-Feb = 2A, March-May = 2D, June-December = 2C (if enrolled)

Why Code 1H: No coverage was offered during January-May because John was either not employed (Jan-Feb) or in a waiting period (March-May). The Line 16 codes provide penalty protection: 2A for months not employed, and 2D for the limited non-assessment period (waiting period).

Scenario 2: Employee Termination Mid-Year

Situation: Beta Industries employs Sarah Johnson as a full-time employee. Sarah is enrolled in health coverage. Sarah resigns effective August 31, 2025.

Correct coding:

  • Line 14: Jan-August = 1E, September-December = 1H
  • Line 15: Jan-August = premium amount, September-December = blank
  • Line 16: Jan-August = 2C, September-December = 2A

Why Code 1H: After termination, the employer has no obligation to offer coverage. Code 1H correctly indicates no coverage was offered for September-December, and Code 2A on Line 16 provides penalty protection because Sarah was not employed during those months.

Scenario 3: Part-Time Employee

Situation: Retail Corp employs Mike Davis as a part-time sales associate. Mike consistently works 20-25 hours per week throughout 2025. Retail Corp does not offer health coverage to part-time employees.

Correct coding:

  • Line 14 (All 12 months): 1H
  • Line 15 (All 12 months): blank
  • Line 16 (All 12 months): 2B

Why Code 1H: Mike is not a full-time employee, so the employer is not required to offer him coverage under the ACA. Code 1H indicates no offer was made, and Code 2B provides penalty protection because Mike was not full-time.

Note: If Retail Corp has a self-insured health plan and Mike enrolls in it (perhaps because the employer voluntarily offers coverage to part-timers), the employer should use Code 1G instead of Code 1H.

Scenario 4: Variable-Hour Employee During Initial Measurement Period

Situation: Healthcare Services Inc. hires Emily Wilson on February 1, 2025 as a variable-hour employee. The employer uses a 12-month initial measurement period starting on the first of the month following hire. Emily's initial measurement period runs from March 1, 2025 through February 28, 2026. During this period, the employer is assessing whether Emily averages 30+ hours per week.

Correct coding for Tax Year 2025:

  • Line 14: January = 1H, February = 1H, March-December = 1H
  • Line 15 (All 12 months): blank
  • Line 16: January = 2A, February-December = 2D

Why Code 1H: Emily is in her initial measurement period for all of 2025 (after her hire date). During this period, the employer is not required to offer her coverage. Code 1H correctly indicates no coverage was offered, and Code 2D provides penalty protection for the initial measurement period.

Scenario 5: Full-Time Employee Not Offered Coverage (No Excuse)

Situation: Manufacturing LLC has 80 full-time employees. Due to an administrative oversight, David Martinez, a full-time warehouse worker, was never enrolled in the company's health plan and was never offered coverage during 2025. David obtained coverage through the Marketplace and received a premium tax credit.

Correct coding:

  • Line 14 (All 12 months): 1H
  • Line 15 (All 12 months): blank
  • Line 16 (All 12 months): Leave blank

Why Code 1H: No coverage was offered to David, so Code 1H is factually correct. However, because David was a full-time employee and no legitimate excuse applies (no waiting period, not terminated, not part-time), Line 16 must be left blank. This will likely trigger a Letter 226-J assessment because David received a premium tax credit while not being offered employer coverage.

Penalty exposure: If Manufacturing LLC offered coverage to at least 95% of full-time employees, they face Penalty B (approximately $4,460) for David. If the oversight affected multiple employees and coverage was offered to less than 95%, they could face the much larger Penalty A.

Scenario 6: Employee Reduced to Part-Time Mid-Year

Situation: Tech Solutions Inc. employs Jennifer Lee as a full-time software developer from January through June. Due to company restructuring, Jennifer's position is reduced to part-time (20 hours/week) effective July 1. Jennifer was enrolled in coverage during her full-time months but loses eligibility when she becomes part-time.

Correct coding:

  • Line 14: Jan-June = 1E, July-December = 1H
  • Line 15: Jan-June = premium amount, July-December = blank
  • Line 16: Jan-June = 2C, July-December = 2B

Why Code 1H for July-December: Once Jennifer became part-time, the employer was no longer required to offer her coverage under the ACA. Code 1H indicates no coverage was offered after the status change, and Code 2B provides penalty protection because Jennifer was not a full-time employee during those months.

Common Mistakes When Using 1095-C Code 1H

Mistake 1: Using Code 1H Without the Appropriate Line 16 Code

The most damaging mistake when using 1095-C Code 1H is failing to include the appropriate Line 16 code when a penalty-protective code applies. If an employee was not employed (2A), not full-time (2B), or in a limited non-assessment period (2D), and you fail to enter the corresponding Line 16 code, the IRS has no way of knowing the employer has an excuse. This can result in penalty assessments that could have been avoided.

How to avoid: Whenever you use Code 1H, always evaluate whether a Line 16 penalty-protection code applies. If the employee was not employed, use 2A. If not full-time, use 2B. If in a waiting period or measurement period, use 2D. Only leave Line 16 blank when no excuse genuinely applies.

Mistake 2: Using Code 1H When Coverage Was Actually Offered

Some employers mistakenly use 1095-C Code 1H when coverage was offered but declined by the employee. This is incorrect. Code 1H means NO coverage was offered, not that coverage was offered and declined. If coverage was offered (even if declined), use the appropriate offer code (1A, 1B, 1C, 1D, 1E, or 1F based on the coverage structure).

How to avoid: Code 1H describes the offer, not the enrollment. If coverage was available to the employee and they had the opportunity to enroll, use an offer code (1A-1F), not Code 1H. Line 16 codes like 2C (enrolled) and safe harbor codes (2F, 2G, 2H) describe what happened after the offer was made.

Mistake 3: Using Code 1H for Non-Full-Time Employees in Self-Insured Plans

If you have a self-insured health plan and cover non-full-time employees (such as part-time workers, retirees, or COBRA participants), you should use Code 1G instead of Code 1H. Code 1G is specifically designed for individuals who are covered under a self-insured plan but who are not full-time employees. Using Code 1H in this situation is incorrect and may cause reporting errors.

How to avoid: For any individual covered under a self-insured plan who is not a full-time employee, use Code 1G with the appropriate Line 16 code.

Mistake 4: Not Reporting Employees with Code 1H at All

Some employers believe that if they did not offer coverage to an employee, they do not need to file a Form 1095-C for that employee. This is incorrect. ALEs must file Form 1095-C for every full-time employee, regardless of whether coverage was offered. Using 1095-C Code 1H with the appropriate Line 16 code is how you report employees who were not offered coverage while still demonstrating penalty protection.

How to avoid: File Form 1095-C for all full-time employees. If no coverage was offered, use Code 1H with the appropriate Line 16 code to explain why.

Mistake 5: Excessive Waiting Periods

The ACA allows a maximum waiting period of 90 days after an employee becomes eligible for coverage. If your waiting period exceeds 90 days, the employee should have been offered coverage, and using 1095-C Code 1H with Code 2D for months beyond the 90-day period is incorrect. The IRS will not accept Code 2D for waiting periods that exceed the legal maximum.

How to avoid: Ensure your waiting period does not exceed 90 days. For new full-time employees, coverage should be offered by the first day of the fourth full calendar month of employment (or earlier, depending on your plan design).

Special Situations Involving Code 1H

COBRA and Code 1H

For former employees who have terminated and are offered COBRA continuation coverage, use 1095-C Code 1H with Code 2A for months after termination. The COBRA offer does not constitute a new coverage offer for ACA reporting purposes because the employee is no longer an employee.

Seasonal and Multi-Employer Plans

Seasonal employees may use 1095-C Code 1H with Code 2A (not employed) or Code 2B (not full-time) depending on specific circumstances. For employees covered under multi-employer (union) plans, employers may use Code 1H with Code 2E on Line 16 when coverage is provided through the union plan.

Filing Deadlines for Form 1095-C

Key Dates for Tax Year 2025

When filing forms with 1095-C Code 1H (or any Line 14 code), employers must meet the following deadlines:

Deadline Requirement Date (Tax Year 2025)
Employee Copies Furnish Form 1095-C to employees March 3, 2026
IRS E-Filing Transmit to IRS electronically March 31, 2026
IRS Paper Filing Mail to IRS (if fewer than 10 forms) February 28, 2026
Extension Automatic 30-day extension via Form 8809 Available

Note: Employers filing 10 or more forms must file electronically. There is no paper filing option for filers above this threshold.

Step-by-Step Guide: Completing Form 1095-C with Code 1H

Step 1: Determine if Coverage Was Offered

Before using 1095-C Code 1H, verify that no coverage was offered to the individual during the month. If coverage was offered (even if declined), use the appropriate offer code (1A-1F). Only use Code 1H when no coverage of any kind was made available.

Step 2: Identify the Appropriate Line 16 Code

When using Code 1H, evaluate whether a penalty-protective Line 16 code applies:

  • Was the employee not employed during the month? Use Code 2A
  • Was the employee not a full-time employee? Use Code 2B
  • Was the employee in a waiting period or initial measurement period? Use Code 2D
  • Is coverage provided through a multi-employer plan? Use Code 2E
  • None of the above apply? Leave Line 16 blank (this creates penalty exposure)

Step 3: Enter Code 1H on Line 14

For each month where no coverage was offered, enter "1H" in the corresponding Line 14 column. If Code 1H applies for all 12 months, you can use the "All 12 Months" column.

Step 4: Leave Line 15 Blank

When using 1095-C Code 1H, Line 15 should always be blank. There is no premium to report when no coverage was offered.

Step 5: Enter the Line 16 Code

Enter the appropriate Line 16 code (2A, 2B, 2D, 2E) for each month where Code 1H applies. If no excuse applies, leave Line 16 blank for that month.

Step 6: Review for Consistency

Before filing, verify that your coding is internally consistent:

  • Code 1H on Line 14 should always have a blank Line 15
  • Line 16 codes should match the employee's circumstances (employment status, waiting period, etc.)
  • If Line 16 is blank with Code 1H, understand that this indicates potential penalty exposure

Frequently Asked Questions About 1095-C Code 1H

What does 1095-C Code 1H mean?

1095-C Code 1H indicates that no health coverage was offered to the individual during a particular month. This code is used when the employer did not make any health coverage available to the employee, regardless of the reason. Line 16 codes explain why coverage was not offered and provide penalty protection when applicable.

When should I use Code 1H instead of another code?

Use 1095-C Code 1H only when no coverage was offered. If coverage was offered (even if the employee declined), use the appropriate offer code (1A through 1F) based on the coverage structure. Code 1H is specifically for situations where no offer was made at all, such as before hire date, after termination, during waiting periods for new employees, or when the employee was not full-time.

Do I need a Line 16 code when using Code 1H?

You should always evaluate whether a Line 16 code applies when using 1095-C Code 1H. If the employee was not employed (2A), not full-time (2B), or in a limited non-assessment period like a waiting period (2D), enter the appropriate code. Only leave Line 16 blank when no legitimate excuse applies. Leaving Line 16 blank with Code 1H for a full-time employee creates penalty exposure.

What are the penalty implications of Code 1H?

Using 1095-C Code 1H for a full-time employee without a penalty-protective Line 16 code can result in employer shared responsibility penalties. If less than 95% of full-time employees receive a coverage offer, Penalty A may apply (approximately $2,970 per full-time employee minus 30 for 2025). For individual full-time employees not offered coverage who receive a Marketplace premium tax credit, Penalty B may apply (approximately $4,460 per employee for 2025).

Can I use Code 1H if the employee declined coverage?

No. 1095-C Code 1H means no coverage was offered, not that coverage was offered and declined. If coverage was offered and the employee declined, use the appropriate offer code (1A, 1B, 1C, 1D, 1E, or 1F) on Line 14. The employee's decision to decline does not change the fact that an offer was made. Line 16 would NOT include Code 2C (enrolled) in this case since the employee declined.

What if an employee is part-time all year?

For employees who are not full-time throughout the year, 1095-C Code 1H with Code 2B (not a full-time employee) on Line 16 is appropriate. This provides full penalty protection because the employer mandate only requires coverage offers to full-time employees. However, if you have a self-insured plan and the part-time employee is enrolled, use Code 1G instead.

Do I need to file Form 1095-C for employees coded 1H all year?

Yes. ALEs must file Form 1095-C for every individual who was a full-time employee for any month during the year. If an employee was full-time for some months (even if coded 1H due to waiting period or termination), a Form 1095-C is required. The only employees who might not receive a 1095-C are those who were never full-time employees at any point during the year AND are not enrolled in a self-insured plan.

What Line 15 entry goes with Code 1H?

Line 15 should be left blank when using 1095-C Code 1H. Line 15 reports the employee's share of the premium for the lowest-cost self-only minimum value coverage. Since Code 1H indicates no coverage was offered, there is no premium to report.

Can I use Code 1H during an employee's waiting period?

Yes. 1095-C Code 1H with Code 2D on Line 16 is appropriate during a legitimate waiting period (up to 90 days after the employee becomes eligible). This combination provides penalty protection because the employer is in a limited non-assessment period. However, if your waiting period exceeds 90 days, Code 2D will not provide protection for the excess months.

What if I made an administrative error and did not offer coverage to a full-time employee?

If a full-time employee was not offered coverage due to administrative error and no legitimate excuse applies, use 1095-C Code 1H with no Line 16 code. This is the factually accurate reporting even though it creates penalty exposure. If the employee received a Marketplace premium tax credit, you will likely receive a Letter 226-J proposing penalties. You may be able to respond to the Letter 226-J with explanations or payment, but the coding should reflect what actually happened.

Is Code 1H appropriate for COBRA participants?

For former employees who have terminated and are offered COBRA, use 1095-C Code 1H with Code 2A (not employed) for months after termination. The COBRA offer is a continuation right, not a new employer coverage offer. The former employee is no longer an employee, so Code 2A applies regardless of whether they elect COBRA.

What is the difference between Code 1H and Code 1G?

Both codes are used for individuals who are not full-time employees, but they apply in different situations. Code 1H indicates no coverage was offered. Code 1G indicates the individual is covered under a self-insured plan but is not a full-time employee (such as a part-time worker, retiree, or COBRA participant enrolled in a self-insured plan). Use Code 1G when coverage is provided; use Code 1H when it is not.

Conclusion: Mastering 1095-C Code 1H

Understanding when to use 1095-C Code 1H is essential for accurate ACA compliance reporting. This code represents situations where no health coverage was offered to an individual during a particular month. Unlike other Line 14 codes that describe various types of coverage offers, Code 1H stands alone as the code indicating the complete absence of a coverage offer. When used for full-time employees, Code 1H creates potential penalty exposure unless accompanied by a penalty-protective Line 16 code that explains why coverage was not offered.

Key takeaways about 1095-C Code 1H:

  • Definition: Code 1H means no coverage was offered during the month
  • Line 15: Always leave blank with Code 1H (no premium to report)
  • Line 16: Critical for penalty protection; use 2A (not employed), 2B (not full-time), or 2D (waiting/measurement period) when applicable
  • Penalty risk: Code 1H without a Line 16 code for full-time employees creates exposure to Penalty A or Penalty B
  • Common errors: Forgetting Line 16 codes, using 1H when coverage was offered but declined, excessive waiting periods
  • Self-insured plans: Use Code 1G (not Code 1H) for non-full-time employees covered under self-insured plans
  • File for all full-time employees: Even employees coded 1H all year need a Form 1095-C if they were ever full-time

By carefully evaluating each employee's employment status, coverage offer status, and eligibility circumstances, and properly completing Lines 14 and 16, you protect your organization from IRS penalties and demonstrate full compliance with the Affordable Care Act. Use the guidance in this article along with tools like BoomTax to ensure accurate reporting for every filing season.
