How is MAGI-based household size determined for subsidy eligibility?

• A. It includes the applicant and all dependents claimed on the tax return who live with the applicant
• B. It includes unrelated individuals living with the applicant
• C. It includes all age groups within the household
• D. It excludes dependents living with the applicant

Answer: (B)

MagI-based household size is determined by who is considered part of the taxpayer’s household for tax purposes. This includes the applicant and the people living with them who would be counted on the tax return as part of the tax household. Unrelated individuals living with the applicant can fall into this category if they are supported by the applicant or would be claimed as dependents, so they count toward MAGI-based household size for subsidy eligibility. The other options either limit to relatives only or omit dependents, which would not reflect how the tax household is defined for MAGI.
