Understanding ACA Form 1095-C Codes
Form 1095-C, Employer-Provided Health Insurance Offer and Coverage is used by ALEs to report information on the health coverage offered to their employees during that calendar year.
If you are an employer, you must include the employee's details and health coverage details on Lines 14, 15, & 16 by using various ACA 1095-C codes to indicate the employee's health insurance offer and coverage.
Here’s what you need to report along these lines:
-
Line 14
Report the type of health coverage plan offered to your employee
-
Line 15
Report the amount of the employee required contribution for each month
-
Line 16
Report the employee's eligibility for health coverage and the coverage status for each month of the calendar year
Form 1095-C Line 14 Codes: Offer of Coverage
On line 14 of the 1095-C Form, employers must use the appropriate 1-Series code (1A-1U) to indicate the type of health insurance coverage offered to the employee, their spouse, and dependents.

The ACA code selection may vary for each employee based on the following factors:
- Whether the employee was offered coverage
- The type of coverage provided
- The months during which coverage was available
If an employee was eligible for health benefits at any time during the year, Line 14 must include a code for each month, even for months when the employee was no longer employed.
Below is a complete list of 1-Series Line 14 codes for Form 1095-C:
Line 14 Codes | Code Description |

This code may be used to report for specific months for which a Qualifying Offer was made, even if you did not receive a Qualifying Offer for all 12 months of the calendar year.

Line 1a. 1095-C Codes for ICHRA Reporting
The IRS mandated the reporting of Individual Coverage Health Reimbursement Arrangements (ICHRA) and introduced new ACA 1095-C codes on Line 14 to ensure compliance with these requirements.
An ICHRA is a relatively new type of health reimbursement arrangement, introduced in 2020, that allows employers of any size to reimburse employees for some or all of the premiums they pay for their own individual health insurance. This provides greater flexibility for both employers and employees in managing health coverage.
To accurately report ICHRA health coverage, employers must use the appropriate ACA codes (1T–1U) on Line 14 of Form 1095-C.
New ICHRA Codes for Line 14 | Code Description |
---|---|
1T |
The Individual coverage HRA offered to the employee and spouse (no dependents) and affordability was determined using the employee's primary residence location ZIP code. |
1U |
The Individual coverage HRA offered to the employee and spouse (no dependents) and affordability was determined using the employee's primary employment site ZIP code affordability safe harbor. |
