your daughter does not need to buy new insurance. she can either stay on your plan and make no change or choose instead to be covered by her employer's plan. the best thing to do is to evaluate both plans to determine which provides better coverage for her needs at the best price. and remember just because two plans are offered by the same insurance company doesn't mean they provide the same benefits.
does my 18 year old daughter have to take the insurance her employer offered her. she just became a full time employee. she is covered on my insurance. she is a full time student and employee. the odd thing is the insurance she was just offered is with the same company i have insurance with. regardless of the outcome will she need to apply/buy insurance from the marketplace?
