Which of the following is NOT a factor in determining APTC eligibility?

• A. Applicant's age
• B. Household income relative to FPL
• C. MAGI
• D. Family size

Answer: (A)

Eligibility for the Advanced Premium Tax Credit is determined by income relative to the federal poverty level, using MAGI, and by family size (which sets the FPL threshold). These factors decide whether you fall into the eligible income range and how large the credit can be. The applicant’s age does not enter the eligibility calculation (age can affect premium amounts in general, but not whether you qualify for the credit). So the correct takeaway is that age is not used to determine APTC eligibility, while MAGI, household income as a percent of FPL, and family size are.
