You can be covered on your parent’s Marketplace plan up to the end of the plan year that follows your 26th birthday. If your parents don’t claim you as a tax dependent (and you file your own taxes), then your eligibility for premium tax credits will be based on your income alone. Some state-run Marketplaces can calculate premium tax credits separately for family policies that cover two “tax households.” However, so far, the federal Marketplace (HealthCare.gov) has not been able to accommodate two tax households enrolling on one application. As a result, many young adults will simply enroll in their own separate policy. If your income is at least $15,060 in 2024, and you meet other requirements, you may qualify for a premium tax credit.

If your own income is between $15,060 and $37,650 in 2024, you may also be eligible for cost sharing subsidies if you enroll in a Silver plan. However, in family policies that cover people in different “tax households,” eligibility for cost sharing subsidies will be based on the tax household that is least eligible. Because your parents are not eligible for financial assistance, you would not be able to receive premium tax credits or cost-sharing reductions under their plan; you would need to enroll in a separate Marketplace plan to access financial assistance.
