Most people who enroll in Marketplace health insurance are eligible for government subsidies – or premium tax credits – that cover some or all of their premium costs. As of early 2024, nearly 21 million people were enrolled in Marketplace coverage, and 93% of them were receiving premium subsidies.1
Fortunately, determining whether you’re eligible for these subsidies isn’t complicated: many entities – including INSXCloud’s affiliate, IHC Specialty Benefits – offer ACA subsidy calculators.
Marketplace subsidy eligibility is based primarily on household income, but there are a few other important points to keep in mind.
First, you must be eligible to use the health insurance Marketplace and enroll in Marketplace coverage. For that, you must:2
Assuming you meet those requirements, you could potentially be eligible for premium subsidies for your Marketplace coverage. Most Marketplace enrollees in 2024 plans were eligible for subsidies.1 Here’s what’s necessary to be Marketplace subsidy-eligible:
If you meet all of those requirements, your eligibility for a premium subsidy will depend on your household’s income and the cost of the benchmark plan (second-lowest-cost Silver plan) in your area.
Subsidy eligibility is based on the percentage of your household income that you would have to pay to purchase the benchmark plan. If it’s more than a certain percentage (on a sliding scale that varies by income), you’ll qualify for a subsidy.
You can use this subsidy calculator – from INSXCloud’s affiliate, IHC Specialty Benefits – to determine whether you might be subsidy-eligible, and if so, see your estimated monthly subsidy amount.
To apply for ACA subsidies, you’ll need to provide some basic personal and financial information. For all family members applying for coverage, this will include:
Once the Marketplace starts processing the application, it will compare the information provided with information from trusted data sources, including the Internal Revenue Service (IRS), Social Security, Equifax, etc.6
If there are inconsistencies between the information the applicant provided and the information the Marketplace gets from the trusted data sources, it will generate a data matching issue.7
If that happens, the Marketplace will reach out to you and ask for proof of the information you provided. For example, the Marketplace might ask for verification documents related to projected household income, citizenship/immigration status, American Indian/Alaska Native status, or applicants’ access to employer-sponsored health insurance, Medicaid/CHIP, or Medicare.8
As noted above, the vast majority of Marketplace enrollees are receiving subsidies, which are paid to their health insurers on their behalf. But that’s just looking at the pool of people enrolled in Marketplace coverage.
Most individuals are not eligible for Marketplace subsidies because they have access to health coverage from an employer,9 Medicaid/CHIP, or Medicare.10
Even if you’re not eligible for government-sponsored coverage or affordable employer-sponsored coverage , subsidies are not available if the full-price premium for the second-lowest-cost Silver plan is less than a certain percentage of your household income. (This is an income-based percentage, which ranges from 0% to 8.5% in 2025.)
And some low-income people in nine states fall into what’s known as the coverage gap. Medicaid is not available because the state hasn’t expanded Medicaid, but subsidies are also not available if household income is under the federal poverty level. (Medicaid expansion is an Affordable Care Act provision that calls for Medicaid to be available to adults under age 65 with household income up to 138% FPL. But a Supreme Court ruling made this optional for states, and ten states have not expanded Medicaid. In nine of those states, many adults with income below the poverty level are not eligible for Medicaid.)
There is no upper age limit for subsidy eligibility. However, as noted above, subsidy eligibility ends once a person becomes eligible for premium-free Medicare Part A. For most people, that happens at age 65.
No, you do not need to be a U.S. citizen to get a premium subsidy. There is a long list of lawfully present immigration statuses that will allow a person to use the Marketplace and potentially qualify for income-based subsidies.11
In most states, recent immigrants cannot qualify for Medicaid until they’ve been in the U.S. for at least five years. Before this, recent immigrants who are lawfully present residents, can use the Marketplace and qualify for Marketplace subsidies, regardless of income. (Applicants with less than five years’ residency must have an income of at least the federal poverty level to qualify for Marketplace subsidies.)
