For ObamaCare, your “household” is your “tax family” (head of household, spouse, and tax dependents). Cost assistance is based on household income and size, the people who share a plan are called a “coverage family.”
With this in mind,
For determining cost assistance under the Affordable Care Act, “household size” is the number of people filing taxes together. This doesn’t have to be the same as the number of people sharing a plan together.
TIP: Don’t include anyone you won’t file taxes with when applying for cost assistance, but DO include anyone you will file with even if they don’t need coverage. Cost assistance is a form of tax credit.
Household income (sometimes called family income) is the income counted for ObamaCare. Household or family income for the ACA is MAGI of the head of household (and spouse if filing jointly) plus the AGI plus the AGI of anyone claimed as a dependent. Once you know your household income you can compare it to the corresponding Federal Poverty Level to understand what cost assistance you are eligible for.
You can learn more about MAGI and AGI here.
Anyone who has filled out form 8962 for the Premium Tax Credit has heard the terms “coverage family” and “tax family,” let’s clarify what that means.
Everyone who shares a plan together is called a “coverage family” and everyone who files taxes together is called a “tax family.” Your “coverage family” and “tax family” don’t have to be the same, for instance, the head of household may have an employer plan while the rest of the family (who doesn’t have access to the plan) gets a plan on the Health Insurance Marketplace or through Medicaid or CHIP.
NOTE: The people you consider to be your “family” don’t have to be your tax family or coverage family.
Household size and household income are counted for the “tax family” filing together, but the “coverage family” (for tax purposes) is only the people on the plan.
Now that you understand the terms and reasoning behind household size, household income, tax family, and coverage family, use the information below for further clarification.
HeatlhCare.Gov states this simply by saying, “follow these basic rules when reporting members of your household.”
