Understanding 1095-C Code 1A: The Complete Guide to the Qualifying Offer
Introduction: What Is 1095-C Code 1A and Why Does It Matter?
If you are responsible for ACA compliance at your organization, understanding when to use 1095-C Code 1A on Form 1095-C is essential. Code 1A, known as the "Qualifying Offer" code, represents the most favorable coverage offer an Applicable Large Employer (ALE) can report on Line 14 of Form 1095-C. This code tells the IRS that your organization offered comprehensive, affordable health coverage to the employee, their spouse, and their dependents at a premium cost that meets specific affordability thresholds.
The stakes for correctly using 1095-C Code 1A are significant. When you properly report Code 1A, you demonstrate to the IRS that your coverage offer meets all requirements of the ACA employer mandate without needing to prove affordability through additional calculations. However, using Code 1A incorrectly can result in IRS scrutiny, penalty assessments through Letter 226-J, and the administrative burden of filing corrections. Understanding exactly when Code 1A applies, and when you should use a different code instead, is crucial for accurate ACA reporting.
This comprehensive guide explains everything you need to know about 1095-C Code 1A, including the specific requirements for using this code, how it compares to other Line 14 codes, common mistakes employers make, and practical examples showing when Code 1A is appropriate. Whether you are filing for a small ALE with 50 employees or a large enterprise with thousands of full-time workers, this guide will ensure you understand how to correctly apply the Qualifying Offer code.
In this guide, you will learn:
- What Code 1A means: The specific requirements for the Qualifying Offer
- The affordability threshold: The exact premium amount that qualifies for Code 1A
- Code 1A vs. Code 1E: Understanding the critical difference between these codes
- Line 15 requirements: Why Line 15 must be left blank when using Code 1A

What Is 1095-C Code 1A: The Qualifying Offer Explained
Definition of Code 1A
1095-C Code 1A is used on Line 14 of Form 1095-C to indicate that an employer made a "Qualifying Offer" to a full-time employee. A Qualifying Offer is a specific type of health coverage offer that meets three distinct requirements simultaneously. When all three requirements are met for all months of the calendar year (or for specific months when the offer was made), the employer may use Code 1A to report the coverage offer.
The three requirements for a Qualifying Offer that allows the use of 1095-C Code 1A are:
- Minimum Value Coverage to the Employee: The employer must offer health coverage that provides minimum value (MV) to the employee. Minimum value means the plan covers at least 60% of the total allowed costs of benefits expected to be incurred under the plan. Most employer-sponsored health plans meet this requirement.
- Affordable Premium at the FPL Threshold: The employee's required contribution for self-only coverage must not exceed 9.02% of the mainland federal poverty line (FPL) for a single individual, divided by 12 to get the monthly amount. For 2025, this equates to approximately $113.20 per month or less.
- Minimum Essential Coverage to Spouse and Dependents: The employer must also offer at least minimum essential coverage (MEC) to the employee's spouse and dependents (children under age 26). The spouse and dependent coverage does not need to be free or affordable; it simply needs to be offered.
When all three conditions are satisfied, the employer has made a Qualifying Offer and may use 1095-C Code 1A on Line 14 for the applicable months.
The FPL Affordability Threshold for Code 1A
The key distinguishing factor of 1095-C Code 1A is the affordability requirement based on the federal poverty line. Unlike other affordability calculations that use the employee's actual wages or rate of pay, the Qualifying Offer uses a fixed threshold based on the FPL. This makes Code 1A particularly straightforward because affordability is determined by a single national standard rather than individual employee circumstances.
For tax year 2025, the ACA affordability threshold is 9.02% of mainland FPL. The 2025 mainland FPL for a single individual is $15,060. The calculation works as follows:
| Calculation Step | Formula | Result |
|---|---|---|
| Annual FPL (2025) | Mainland single individual | $15,060 |
| Affordability Percentage | 9.02% of FPL | $1,358.41 |
| Monthly Threshold | $1,358.41 / 12 | $113.20 |
If your employee's monthly contribution for self-only minimum value coverage is $113.20 or less, and you also offer coverage to their spouse and dependents, you can use 1095-C Code 1A.
Important: The FPL threshold is adjusted annually. Always verify the current year's threshold before completing Form 1095-C. The IRS publishes updated affordability percentages and FPL amounts each year.
Who Can Use 1095-C Code 1A?
1095-C Code 1A can be used by any Applicable Large Employer that meets the Qualifying Offer requirements. This includes:
- Single employers: Standalone companies with 50 or more full-time employees (including full-time equivalents)
- Controlled group members: Companies that are part of a controlled group where the combined group meets the ALE threshold
- Government entities: Federal, state, and local government employers that are ALEs
- Non-profit organizations: Tax-exempt entities that meet the ALE definition
Code 1A can be used for any full-time employee who received a Qualifying Offer, regardless of whether the employee actually enrolled in the coverage or declined it. The code reports what was offered, not what was accepted.
1095-C Code 1A vs. Code 1E: Understanding the Critical Difference
When to Use Code 1A vs. Code 1E
One of the most common points of confusion in ACA reporting is the difference between 1095-C Code 1A and Code 1E. Both codes indicate that the employer offered minimum value coverage to the employee and at least minimum essential coverage to the employee's spouse and dependents. However, there is one crucial difference: affordability.
| Characteristic | Code 1A (Qualifying Offer) | Code 1E (MV to Employee, MEC to Spouse/Dependents) |
|---|---|---|
| Coverage to Employee | Minimum Value | Minimum Value |
| Coverage to Spouse | Minimum Essential Coverage | Minimum Essential Coverage |
| Coverage to Dependents | Minimum Essential Coverage | Minimum Essential Coverage |
| Affordability Requirement | Employee premium ≤ 9.02% FPL ($113.20/month for 2025) | No specific affordability indicated by the code |
| Line 15 Entry | Leave blank | Enter premium amount |
| Line 16 Safe Harbor Needed? | Not required (affordability built into code) | Typically yes (2F, 2G, or 2H) |
The key takeaway: Use 1095-C Code 1A when your employee contribution is at or below the FPL threshold ($113.20/month for 2025). Use Code 1E when you offer the same coverage but the employee contribution exceeds this threshold. With Code 1E, you must enter the actual premium on Line 15 and typically use a safe harbor code on Line 16 to demonstrate affordability.
Example: Choosing Between Code 1A and Code 1E
Scenario A: ABC Manufacturing
ABC Manufacturing offers health coverage to all full-time employees. The employee contribution for self-only coverage is $100 per month. Coverage is also available to spouses and dependents.
Correct Code: 1A (Qualifying Offer)
Why: The $100 monthly premium is below the $113.20 FPL threshold for 2025. All three Qualifying Offer requirements are met.
Scenario B: XYZ Technology
XYZ Technology offers health coverage to all full-time employees. The employee contribution for self-only coverage is $175 per month. Coverage is also available to spouses and dependents.
Correct Code: 1E (MV to Employee + Spouse + Dependents)
Why: The $175 monthly premium exceeds the $113.20 FPL threshold. The employer must use Code 1E, enter "$175.00" on Line 15, and use an appropriate safe harbor code on Line 16 (such as 2F for W-2 safe harbor or 2G for rate of pay safe harbor) to demonstrate affordability based on the employee's actual income.
Line 15 Requirements When Using 1095-C Code 1A
Why Line 15 Must Be Left Blank
When using 1095-C Code 1A, employers must leave Line 15 blank. This is not optional; it is a requirement. The reason is straightforward: Code 1A already incorporates the affordability determination based on the federal poverty line. The IRS knows the maximum permitted premium amount based on the FPL calculation, so entering a dollar amount on Line 15 is unnecessary and incorrect.
Entering a value on Line 15 when Code 1A is used may cause processing issues with the IRS and could trigger error notices. The IRS validation rules expect Line 15 to be empty when Code 1A appears on Line 14.
Summary of Line 15 rules for Line 14 codes:
| Line 14 Code | Line 15 Requirement |
|---|---|
| 1A (Qualifying Offer) | Leave blank |
| 1B, 1C, 1D, 1E | Enter employee's monthly premium for self-only MV coverage |
| 1G (Non-FT in self-insured) | Leave blank |
| 1H (No offer) | Leave blank |
| 1J-1M (ICHRA) | Enter monthly ICHRA allowance |
| 1N-1Q (ICHRA Qualifying) | Leave blank |
Line 16 Requirements with Code 1A
When using 1095-C Code 1A, Line 16 does not require a safe harbor code because the Qualifying Offer itself establishes affordability. However, you may still use certain Line 16 codes alongside Code 1A:
- 2C (Enrolled in Coverage): Use Code 2C on Line 16 if the employee actually enrolled in your health coverage. This is the most common Line 16 code used with Code 1A when the employee accepted the offer.
- No Code Needed: If the employee declined the Qualifying Offer and did not enroll, you may leave Line 16 blank. There is no penalty risk because Code 1A already demonstrates a proper coverage offer was made.
Note: You do NOT need to use safe harbor codes (2F, 2G, 2H) with Code 1A. These codes are used with codes like 1E where affordability must be demonstrated separately.
Real-World Scenarios: When to Use 1095-C Code 1A
Scenario 1: Full-Time Employee Enrolled All Year
Situation: Sarah works full-time for Regional Health Services throughout 2025. The employer offers health coverage to employees, spouses, and dependents. The employee contribution for self-only coverage is $100/month. Sarah enrolls herself, her spouse, and her child in the plan.
Correct coding:
- Line 14 (All 12 months): 1A
- Line 15: Leave blank
- Line 16 (All 12 months): 2C (enrolled in coverage)
Why Code 1A: The $100 premium is below the $113.20 FPL threshold. MV coverage was offered to the employee, and MEC was offered to the spouse and dependents. All Qualifying Offer requirements are met.
Scenario 2: Full-Time Employee Declines Coverage
Situation: Michael works full-time for Tech Solutions Inc. throughout 2025. The employer offers health coverage at $110/month for self-only, with coverage available for spouses and dependents. Michael declines because he has coverage through his spouse's employer.
Correct coding:
- Line 14 (All 12 months): 1A
- Line 15: Leave blank
- Line 16: Leave blank (no enrollment, but offer was made)
Why Code 1A: The code reflects the offer made, not whether the employee enrolled. The $110 premium is below the FPL threshold, making this a Qualifying Offer regardless of Michael's decision to decline.
Scenario 3: New Hire with Waiting Period
Situation: Jennifer is hired on March 1, 2025. She completes a 60-day waiting period and becomes eligible for coverage on May 1. The employer offers Qualifying Offer coverage (self-only premium $105/month, spouse and dependents available). Jennifer enrolls effective May 1.
Correct coding:
- Line 14: January-February = 1H, March-April = 1H, May-December = 1A
- Line 15: Leave blank for all months
- Line 16: January-February = 2A (not employed), March-April = 2D (waiting period), May-December = 2C (enrolled)
Why Code 1A for May-December: Once eligible, Jennifer received a Qualifying Offer with premium below the FPL threshold.
Scenario 4: Mid-Year Premium Increase
Situation: DataCorp has a health plan with employee premiums of $100/month from January through June. Starting July 1, premiums increase to $125/month due to plan changes. Coverage is offered to employees, spouses, and dependents throughout the year.
Correct coding:
- Line 14: January-June = 1A, July-December = 1E
- Line 15: January-June = blank, July-December = $125.00
- Line 16: Use 2C if enrolled; use appropriate safe harbor (2F, 2G, 2H) for July-December if not enrolled
Why the change: Code 1A only applies when the premium is at or below the FPL threshold. When the premium increased above $113.20/month in July, the employer must switch to Code 1E and report the actual premium on Line 15.
Scenario 5: Employee-Only Coverage (Not Qualifying Offer)
Situation: Budget Retail offers health coverage to employees only, with no option for spouses or dependents. The employee premium is $90/month.
Correct coding:
- Line 14: 1B (MV to employee only)
- Line 15: $90.00
- Line 16: 2C if enrolled; safe harbor code if not enrolled
Why NOT Code 1A: Even though the premium is below the FPL threshold, 1095-C Code 1A cannot be used because coverage is not offered to spouses and dependents. Code 1A requires all three components of the Qualifying Offer.
Common Mistakes When Using 1095-C Code 1A
Mistake 1: Using Code 1A When Premium Exceeds FPL Threshold
The most frequent error is using 1095-C Code 1A when the employee contribution exceeds the FPL-based threshold. If your self-only premium is $115, $150, or any amount above $113.20/month (for 2025), you cannot use Code 1A. You must use Code 1E instead and demonstrate affordability through Line 15 and Line 16.
How to avoid: Before filing, compare your employee premium to the current year's FPL threshold. Only use Code 1A if your premium is at or below the threshold.
Mistake 2: Using Code 1A Without Spouse/Dependent Coverage
Some employers mistakenly use 1095-C Code 1A when they offer affordable employee-only coverage but do not extend coverage to spouses and dependents. The Qualifying Offer requires MEC to be available to family members, even if the employer does not subsidize that coverage.
How to avoid: Verify that your health plan allows spouses and dependents to enroll. If your plan only covers employees, use Code 1B (employee only) regardless of how low the premium is.
Mistake 3: Entering a Value on Line 15
When using 1095-C Code 1A, Line 15 must be left blank. Some employers enter the premium amount anyway, thinking it provides additional documentation. This creates processing errors and may trigger IRS notices.
How to avoid: Remember that Code 1A inherently communicates affordability at the FPL level. Leave Line 15 empty when using this code.
Mistake 4: Not Tracking Monthly Changes
If your employee premium changes during the year, you may need to use different codes for different months. Using Code 1A for all 12 months when it only applied for part of the year is incorrect.
How to avoid: Track your premium amounts throughout the year. If mid-year changes push your premium above the FPL threshold, switch to Code 1E for those months.
Mistake 5: Confusing the FPL Threshold with Other Safe Harbors
The FPL-based Qualifying Offer threshold (9.02% of FPL) is different from the affordability safe harbors used on Line 16. Some employers confuse the federal poverty line safe harbor (Code 2H on Line 16) with the Qualifying Offer. These are related but distinct concepts.
How to avoid: Understand that Code 1A is a Line 14 code indicating the type of offer made. The Line 16 safe harbor codes (2F, 2G, 2H) are used with codes like 1E to prove affordability based on different calculation methods. Code 1A does not require a Line 16 safe harbor.
Penalties for Incorrect Coding
Information Return Penalties
Incorrect use of 1095-C Code 1A can result in information return penalties assessed by the IRS. The penalty amounts for Tax Year 2025 filings are:
- $60 per form if corrected within 30 days of the filing deadline
- $130 per form if corrected after 30 days but by August 1
- $330 per form if not corrected by August 1
- $660+ per form for intentional disregard (no maximum)
These penalties can accumulate quickly for large employers with hundreds or thousands of 1095-C forms. Filing accurate forms the first time is far less costly than corrections.
Employer Shared Responsibility Penalties
Beyond information return penalties, incorrect coding can lead to employer shared responsibility penalties (ESRP) if the IRS determines that your organization failed to offer affordable, minimum value coverage. Two types of penalties apply:
- Penalty A: Approximately $2,970 per full-time employee (minus 30) for 2025 if coverage is not offered to at least 95% of full-time employees
- Penalty B: Approximately $4,460 per employee for 2025 if coverage is offered but is not affordable or does not meet minimum value, and the employee receives a premium tax credit
If you incorrectly use Code 1A when your premium actually exceeds the FPL threshold, and an employee obtains Marketplace coverage with a premium tax credit, the IRS may assess Penalty B based on the incorrect reporting.
How to Avoid Penalties
The best way to avoid ACA penalties is to ensure accurate coding from the start. Use 1095-C Code 1A only when all three Qualifying Offer requirements are met. If you discover an error after filing, file corrected forms promptly to minimize penalty exposure.
Filing Deadlines for Form 1095-C
Key Dates for Tax Year 2025
When filing forms with 1095-C Code 1A (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 < 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.
Frequently Asked Questions About 1095-C Code 1A
What does 1095-C Code 1A mean?
1095-C Code 1A indicates that the employer made a "Qualifying Offer" to the employee. This means the employer offered minimum value health coverage to the employee at a cost not exceeding 9.02% of the federal poverty line (approximately $113.20/month for 2025), and also offered at least minimum essential coverage to the employee's spouse and dependents.
When should I use Code 1A instead of Code 1E?
Use 1095-C Code 1A when your employee's self-only premium is at or below the FPL threshold ($113.20/month for 2025) AND you offer coverage to spouses and dependents. Use Code 1E when you offer the same family coverage but the employee premium exceeds the FPL threshold. With Code 1E, you must enter the premium on Line 15 and typically use a safe harbor code on Line 16.
Do I need to enter anything on Line 15 when using Code 1A?
No. When using 1095-C Code 1A, Line 15 must be left blank. The Qualifying Offer code already incorporates the affordability determination based on the federal poverty line, so no additional premium information is needed.
Can I use Code 1A if I only offer coverage to employees?
No. 1095-C Code 1A requires that coverage be offered to the employee, spouse, AND dependents. If you only offer employee-only coverage, use Code 1B regardless of how affordable the premium is. The Qualifying Offer has three mandatory components that must all be present.
What is the 2025 FPL threshold for Code 1A?
For tax year 2025, the Qualifying Offer threshold is $113.20 per month (9.02% of the $15,060 mainland FPL divided by 12). If your employee's monthly premium for self-only coverage is at or below this amount, and you offer spouse/dependent coverage, you can use 1095-C Code 1A.
What Line 16 code should I use with Code 1A?
When using 1095-C Code 1A, the most common Line 16 code is 2C (employee enrolled in coverage). If the employee declined the offer, you may leave Line 16 blank. You do NOT need safe harbor codes (2F, 2G, 2H) with Code 1A because affordability is built into the Qualifying Offer.
What happens if I use the wrong code?
Using the wrong Line 14 code can result in IRS penalties for incorrect information returns ($60 to $330+ per form) and may trigger employer shared responsibility penalty assessments if the IRS determines coverage was not properly offered. If you discover an error, file corrected forms as soon as possible.
Can I use Code 1A for only some months of the year?
Yes. If your premium meets the Qualifying Offer threshold for only part of the year (for example, before a mid-year premium increase), you can use 1095-C Code 1A for those months and a different code (like 1E) for months when the threshold was exceeded. Each month can have a different code based on the actual circumstances.
Does the employee need to enroll for me to use Code 1A?
No. 1095-C Code 1A describes the offer made, not whether the employee accepted. If you made a Qualifying Offer and the employee declined, you still use Code 1A to report that a proper offer was made. Line 16 will indicate whether the employee enrolled (2C) or not.
Is Code 1A available for ICHRA offers?
No. Individual Coverage HRAs (ICHRAs) have their own set of Line 14 codes (1J through 1T). ICHRA qualifying offers use codes like 1N, 1O, 1P, and 1Q. The standard 1095-C Code 1A is for traditional group health plan offers, not ICHRAs.
What if my premium is exactly $113.20?
If your employee premium is exactly equal to the FPL threshold, you can use 1095-C Code 1A. The requirement is that the premium not exceed 9.02% of FPL, so premiums at or below the threshold qualify.
Do I need to offer free coverage to spouses and dependents for Code 1A?
No. The Qualifying Offer requires that coverage be offered to spouses and dependents, but there is no requirement that this coverage be affordable or free. The 9.02% FPL threshold only applies to the employee's self-only coverage. Spouse and dependent coverage can be offered at any price, as long as it is available.
