The 2023 poverty level numbers, published in January, 2023, are used to determine subsidy eligibility for 2024 coverage. For a single person in the continental United States, the 2023 federal poverty level is $14,580. For each additional person in the household, the federal poverty level increases by $5,140. (So for a household of three, for example, the 2023 federal poverty level is $24,860.) But to determine 2024 eligibility for Medicaid and CHIP, states switched to the 2024 FPL numbers by March or April 2024. For private health plans, the Marketplaces will start to use the 2024 FPL numbers in November 2024, when subsidy eligibility is being calculated for 2025 coverage.
