How Old Can You Be To Be On Your Parents Health Insurance? 
Children can remain on their parents ' health insurance plan until they turn 25 . This is remains true even if the child is not a student , does n't live with their parents , or even when they are married . Prior to the Affordable Care Act , the cutoff age for most policies was age 19 or 21 unless the they were enrolled in school . Under the new laws , the child can choose to remain on their parents ' plan until they are age 26 , or get their own insurance . Because many people under 25 have smaller incomes , it can be beneficial for them to visit their state 's exchange website to determine if there would be cost savings by purchasing their own insurance .
