Am I Responsible Child’s Coverage Under ObamaCare?
Under Obamacare, if I am responsible for my daughter’s insurance if she is under 26, does that make me responsible for her child?
Whomever files for a dependent is responsible for their coverage and will owe the fee if the dependent doesn't obtain and maintain coverage or an exemption. This is true even if they would otherwise be responsible for their own coverage. If you claim their child, you are responsible for the coverage. On the plus side, each person you add to your tax family increases the cost assistance amount you are eligible for.
