Guide to Data Reporting
Creating Your Dependent Datasheet
Self-Insured or Level Funded Health Plans Only
Entering Your Dependent Data
If your company has a Self-Insured or Level Funded Health Plan, you are required to provide the IRS with coverage information for all dependents that were covered under your health insurance plan during the reporting year.
This guide will walk you through the process of documenting that information for ACA Track, so it can be included in your 1095C's.
If your company has a fully insured health plan, you DO NOT need to complete the dependent datasheet as part of your annual filing. Your health insurance provider will report dependent data to the IRS.
When reporting dependents, you must provide basic, identifying information about the covered individual, the employee they were dependents of, and the dates of their coverage.

Employee SSN (Social Security Number)
- Enter the SSN for the employee associated with this dependent.
- Formatting Requirements: SSN can be entered with or without the dashes: 123-45-6789 OR 123456789. You must include all 9 digits, even if the SSN begins with 0.
Dependent SSN (Social Security Number)
- Enter the dependent’s Social Security Number.
- Formatting Requirements: SSN can be entered with or without the dashes: 123-45-6789 OR 123456789. You must include all 9 digits, even if the SSN begins with 0.
*Note: The IRS requires self-insured employers to make a “reasonable effort” to obtain Social Security numbers for all individuals covered under their insurance plan. If, after making a reasonable effort, you are unable to obtain a dependent’s SSN, you can instead provide a date of birth for that covered individual. For your protection, we recommend that you document all attempts to obtain a dependents Social Security number, as the IRS may require proof of reasonable effort.

When entering Social Security numbers into your spreadsheet, we recommend using Excel’s Special formatting for Social Security numbers. (This will help prevent upload errors from beginning 0's disappearing)
Dependent First Name, Dependent Last Name
- These fields should contain the dependent’s full legal name.
- Formatting Requirements: These fields should contain text only.
Dependent DOB
- This field is only required if you are unable (after multiple attempts) to obtain the dependent’s SSN. If you have entered the dependent’s SSN, this field should be left blank.
- Formatting Requirements: mm/dd/yyyy
Dependent Start Date
- Enter the date the dependent first had coverage under the plan. If the dependent’s coverage began in a previous year, you can enter their original coverage date or 1/1/20xx (in which xx is the reporting year).
- Formatting Requirements: mm/dd/yyyy
Dependent End Date
- If the dependent is no longer covered by your self-insured health plan, this field is required.
- If the dependent stopped coverage at some point in the year and then resumed coverage later in the year, this field should be filled in to document their leaving the plan, and a second line should be created showing their returning to the plan.
- Formatting Requirements: mm/dd/yyyy
Handling Dependent Changes
Most dependents will only require a single line of data, since most of these fields should not change throughout the year.
If a dependent is taken off your insurance plan and then added back on at any point in the year, you will need to provide a separate line of data for each period of coverage.
Make sure to capture both the original Dependent End Date and the new Dependent Start Date:

Note: The new Start Date must be after the original End Date.
Loading Your Dependent Data
When you’re ready to load your Dependent Data into the ACA Track system:

- Your Employee Data file must be error-free, and status must be "Data Upload Complete" BEFORE loading your Dependent Data. The ACA Track system checks your dependent file to ensure each Employee SSN matches an Employee SSN you have previously loaded into our databases. If your employee data hasn’t already been successfully uploaded, your dependent data batch will be rejected.
- When selecting your Data Source, make sure to specify that this is Dependent Data.
Refer to the Loading Data Guide for specific instructions on loading your Dependent Data.
