I work part-time. Am I eligible for a premium subsidy to help me buy insurance?

Q. I work part-time. Am I eligible for a premium subsidy to help me buy insurance?

A. Your eligibility for a premium subsidy isn’t tied to how many hours you work. It’s based on your total household income and what percentage of that income you would have to pay to buy the benchmark plan in your area. To qualify for subsidies, you also have to be legally present in the U.S., not have access to an employer’s health insurance plan that is considered affordable and provides minimum value, and not be eligible for Medicaid, CHIP, or premium-free Medicare.

To be eligible for a Marketplace premium subsidy, your income has to be at least 100% of the federal poverty level (FPL), or more than 138% of FPL, depending on whether you’re in a state that has expanded Medicaid (more about that in a moment).

Normally, there’s an upper cap on subsidy eligibility at 400% of the poverty level, meaning that applicants with household income (an ACA-specific calculation) above that level wouldn’t be eligible for a subsidy. But from 2021 through 2025, the American Rescue Plan and Inflation Reduction Act have eliminated that upper income limit. Subsidies are available through 2025 for households with income above 400% of the poverty level if their cost for the benchmark plan would otherwise exceed 8.5% of the household’s income.

Subsidies are larger from 2021 through 2025

In addition to eliminating the “subsidy cliff,” the American Rescue Plan and Inflation Reduction Act have also made premium subsidies larger for people who were already subsidy-eligible. This is because the law has reduced the percentage of income that people are expected to pay (after the subsidy is applied) for the benchmark plan.

A more detailed explanation of subsidy eligibility determination is available here. In addition, brokers, navigators, and your state’s exchange can help you determine exactly how much your premiums will be for different plans, and whether or not you qualify for a subsidy.

Lower income threshold for subsidy eligibility depends on whether your state has expanded Medicaid

In the majority of the country, Medicaid expansion means that Medicaid is available to adults with income up to 138% of the poverty level (it’s higher than this for kids, with varying limits by state). A person who is eligible for Medicaid is not eligible for premium subsidies, so subsidy eligibility for adults actually starts at 139% of the poverty level in most states (DC, Minnesota, New York, and Oregon have higher low-end thresholds for subsidy eligibility, because of higher Medicaid limits and Basic Health Programs).

And because kids are eligible for Medicaid or CHIP in households with income well above 139% of the poverty level,¹ it’s common to see a household where only the adults are subsidy-eligible, with the kids covered instead by Medicaid or CHIP.

For 2024 and early 2025 coverage, Medicaid eligibility in most states extends to $20,782 for a single adult² (under the age of 65), which means premium subsidy eligibility starts above that level. (New poverty level numbers are published by the federal government in mid-late January each year, and most states start to use those numbers to determine Medicaid eligibility starting in March or April.)

In the states that have not expanded Medicaid, the lower income threshold for a premium subsidy in 2025 is $15,060 (this is the 2024 poverty level for a single adult in the continental U.S.;² the prior year’s poverty level numbers are used for subsidy eligibility, whereas the current year’s poverty level numbers are used to determine Medicaid and CHIP eligibility).

If you’re in a state that hasn’t expanded Medicaid and your income is below the poverty level, you’re likely not eligible for Medicaid or premium subsidies, and are stuck in what’s known as the coverage gap (note that this is the state’s decision; the ACA called for Medicaid eligibility for people in this situation, but a dwindling minority of the states still refuse to accept federal funding to expand Medicaid eligibility).

However, recent immigrants can qualify for subsidies with income below the poverty level. This was built into the ACA, since recent immigrants are ineligible for Medicaid. (Lawmakers had no way of knowing that the Supreme Court would subsequently rule that Medicaid expansion was optional, and that some states would thus refuse to expand Medicaid and leave their lowest-income residents with no access to financial assistance with their health coverage.)
