A dependent is a person who relies on your health insurance coverage — typically a spouse, domestic partner, or child. Dependents can be added to your plan during Open Enrollment or within 60 days of a qualifying life event (like marriage, birth, or adoption).
Under the ACA, you can keep children on your health plan until they turn 26, regardless of whether they are married, in school, living at home, or financially independent. This applies to biological children, stepchildren, and legally adopted children.
Who qualifies as a dependent for health insurance purposes is separate from who qualifies as a dependent for tax purposes. Your insurer’s definition governs who you can add to your plan. Domestic partners are recognized by many plans but are not federally mandated — check your specific plan.
Yes, until age 26. Federal law requires plans that cover dependents to allow children to stay on a parent’s plan until they turn 26. Coverage ends on their 26th birthday, which triggers a qualifying life event — they have 60 days to enroll in their own plan through the Marketplace or an employer.
Not necessarily. Tax dependents are defined by IRS rules. Health insurance dependents are defined by your plan’s terms. Someone can be on your health plan without being claimed as a tax dependent, and vice versa. Always verify your plan’s specific dependent eligibility rules.
