Short answer: Possibly, for your family even if not for you. Since 2023, affordability is judged separately for the employee (self-only cost) and for family members (full family premium), so your family may qualify even when your own offer is affordable.
This change fixed what was known as the “family glitch.” Before 2023, if an employee’s self-only coverage was affordable, the entire family was locked out of premium tax credits, even when covering the family cost far more. Now there are two separate tests: one for the employee based on the self-only premium, and one for family members based on the total cost of family coverage.
When you apply, the Marketplace checks whether the job-based premiums are considered affordable for you (the employee) and for others in your household. If the family coverage is not affordable, your family members may receive savings while you, the employee, generally still cannot if your own self-only offer is affordable. Bringing your employer’s premium details, or a completed Employer Coverage Tool, helps the application come out right.
