Which statement regarding APTC/CSR eligibility is true?

The statement that APTC (Advanced Premium Tax Credit) and CSR (Cost-Sharing Reduction) eligibility is maintained unless total household income exceeds the threshold is correct. This means that as long as the household income remains within specified limits, individuals will continue to qualify for financial assistance to help lower their monthly premium costs and out-of-pocket expenses for health plans purchased through the marketplace.

Income levels are determined as a percentage of the federal poverty level (FPL), and eligibility for APTC and CSR is specifically tied to these income levels. If the total household income increases beyond the income threshold set by the federal guidelines, it can result in the loss of these benefits. However, significant changes in income may not lead to an immediate cancellation, as it would require verification through the marketplace process.

The other options do not accurately reflect the nature of APTC and CSR eligibility. The cancellation of APTC/CSR is not necessarily triggered by any income change from a household member, nor is it confined only to children, and while there is an annual renewal process, it is not fully automatic without any verification of current income.
