I'm on a parent's health plan. How does my income affect their eligibility for health insurance subsidies?
That depends on how you file your taxes. If you and your parents file taxes separately, your income will also be counted separately, even if you are still on their health plan. This means that your “household” and theirs can each qualify for premium subsidies (premium tax credits). If you qualify for a subsidy, you can choose to have it applied to your parent’s premiums. You can also opt to claim it on your taxes instead. If both households are eligible for premium subsidies, the subsidies can be combined.
If your parents still claim you as a dependent on their taxes, your income’s impact on their eligibility will depend on how much you earn. Income from a dependent’s job which exceeds $12,000 annually will count towards the household’s eligibility for subsidies. Anything beneath that amount will not impact the household’s subsidy eligibility.
My boyfriend and I live together but are unmarried. Do we count as a household of one or two?
