Which of the following is NOT a requirement for eligibility for on-exchange HP?

The requirement that is NOT necessary for eligibility for on-exchange health plans (HP) is having a high annual income. The Affordable Care Act (ACA) established that individuals can apply for marketplace insurance regardless of their income level, although financial assistance and subsidies are available for those with lower incomes.

Eligibility criteria for on-exchange health plans focus on residency and citizenship status, as well as criminal status, rather than specifically setting a high annual income as a prerequisite. Thus, individuals with varying income levels can still qualify for coverage options available through the health insurance marketplace, making income a non-restrictive factor in this context.
