Health insurance costs can be a significant burden, particularly for individuals and families with limited incomes. Recognizing this challenge, the Affordable Care Act (ACA) includes provisions to make health coverage more accessible and affordable. This article delves into the financial assistance programs available under the ACA, specifically focusing on how they benefit low-income individuals seeking health insurance through the Health Insurance Marketplace.
Navigating Health Insurance Marketplace Subsidies
The ACA offers crucial financial aid through the Health Insurance Marketplace, also known as exchanges, to help eligible individuals manage the costs of health coverage. These subsidies come in two primary forms: Premium Tax Credits and Cost Sharing Reductions. Both are designed to lower your healthcare expenses, but they target different aspects of your insurance costs. To benefit from either of these programs, you must enroll in a health plan offered through the Health Insurance Marketplace in your state.
Premium Tax Credits: Lowering Your Monthly Premiums
Premium tax credits are designed to reduce your monthly health insurance payments, making coverage more affordable upfront. These credits can be applied to plans across all metal tiers available on the Marketplace: bronze, silver, gold, and platinum. It’s important to understand the tier system: bronze plans typically have the lowest monthly premiums but come with higher deductibles and out-of-pocket costs when you need medical care. Conversely, platinum plans have the highest premiums but offer very low out-of-pocket expenses.

Catastrophic health plans are also available on the Marketplace, offering even lower premiums than bronze plans but with very high deductibles and cost sharing. However, these plans are generally restricted to individuals under 30 years of age, and importantly, premium tax credits cannot be applied to catastrophic plans. Therefore, for those seeking Affordable Care Act Low Income Health Program benefits, focusing on bronze through platinum plans is crucial.
Who Qualifies for Premium Tax Credits?
Eligibility for premium tax credits in 2025 depends on several key factors. To qualify, an individual must:
- Income Level: Have a household income that is at least 100% of the Federal Poverty Level (FPL). The specific FPL for 2025 eligibility is based on the 2024 poverty guidelines.
- Employer-Sponsored Insurance: Not have access to affordable and minimum-value health coverage through an employer, including a family member’s employer. For 2025, employer-sponsored coverage is considered “affordable” if the employee’s premium contribution for self-only coverage is 9.02% or less of their household income. The coverage must also meet a minimum value standard, covering at least 60% of total allowed costs.
- Government Programs: Not be eligible for coverage through government programs like Medicare, Medicaid, or the Children’s Health Insurance Program (CHIP).
- Citizenship/Legal Residency: Be a U.S. citizen or have proof of legal residency. Lawfully present immigrants with incomes below 100% FPL may also be eligible for Marketplace subsidies if they meet other requirements.
- Tax Filing Status: If married, must file taxes jointly.
Defining Household Income: For premium tax credit purposes, household income is defined as Modified Adjusted Gross Income (MAGI). MAGI includes income sources like wages, salaries, foreign income, interest, dividends, and Social Security benefits for the taxpayer, their spouse (if filing jointly), and tax dependents.
Understanding Employer Coverage and the “Family Glitch”: The affordability of employer-sponsored coverage is assessed based on the cost of self-only coverage. If self-only coverage is considered affordable (less than 9.02% of household income), the employee is generally not eligible for Marketplace subsidies. However, a situation known as the “family glitch” can occur. If the cost of family coverage through an employer is more than 9.02% of household income, but self-only coverage is affordable, the dependents (spouse and children) may be eligible for subsidized Marketplace coverage, even if the employee is not. This is a critical point for families seeking affordable care act low income health program options when one spouse has employer coverage.
Medicaid Eligibility and the Coverage Gap: In states that have expanded Medicaid under the ACA, adults with incomes up to 138% FPL are typically eligible for Medicaid, not Marketplace subsidies. However, in non-expansion states, adults with incomes as low as 100% FPL can qualify for Marketplace subsidies. A significant coverage gap exists in non-expansion states, where individuals with incomes below 100% FPL may not qualify for either Medicaid or Marketplace subsidies.
Immigrant Eligibility: Specific rules apply to immigrants. Lawfully present immigrants generally must meet a five-year residency requirement for Medicaid eligibility (with exceptions). However, some lawfully present immigrants below 100% FPL may still qualify for Marketplace tax credits. Recently, DACA recipients have also been made eligible for Marketplace coverage, further expanding access to affordable care act low income health programs.
Calculating Your Premium Tax Credit Amount
The premium tax credit is calculated to limit your contribution towards the “benchmark” plan premium. The benchmark plan is defined as the second-lowest cost silver plan available in your Marketplace area. Your “required individual contribution” towards this benchmark premium is set on a sliding income scale.

For example, in 2025, individuals with incomes up to 150% FPL have a required contribution of 0%, while those with incomes at or above 400% FPL have a required contribution of 8.5% of their household income. The American Rescue Plan Act (ARPA) and the Inflation Reduction Act (IRA) have temporarily enhanced these subsidies, making them more generous than before.
The actual tax credit amount is the difference between the benchmark plan’s cost and your required contribution. This credit can then be applied to any Marketplace plan (except catastrophic plans). If you choose a plan that is more expensive than the benchmark plan, you pay the difference. If you select a less expensive plan, the tax credit covers a larger portion, potentially even covering the entire premium, resulting in a zero-premium plan.
Limitations on Premium Tax Credit Application: The premium tax credit generally applies to essential health benefits (EHBs). It may not cover portions of the premium for non-EHB benefits like adult dental or for the separate $1 monthly premium some plans charge for abortion coverage. Additionally, tobacco surcharges are not covered by the premium tax credit.
Receiving Your Premium Tax Credit: Advance Payments or Tax Refund
To receive the premium tax credit, you must apply for coverage through the Health Insurance Marketplace and provide information about your household, income, and other relevant details. After application, you’ll receive a determination of your potential tax credit amount. You have options for how to receive the credit:
- Advance Premium Tax Credit (APTC): You can choose to have the tax credit paid in advance, directly to your insurance plan each month. This reduces your monthly premium payments. However, APTC is based on estimated income, so you must reconcile it when you file your taxes the following year. If your actual income is different from your estimate, you may receive a larger tax refund or owe back some of the credit.
- Claiming the Credit on Your Tax Return: You can choose to pay your full premium each month and claim the entire tax credit when you file your annual tax return. While this requires more upfront payment, it avoids potential reconciliation issues.
Most Marketplace enrollees utilize the APTC option to make monthly premiums more manageable. It’s crucial to file your taxes every year to reconcile APTC and maintain eligibility for future subsidies. Failure to file and reconcile for two consecutive years can result in ineligibility for premium tax credits. The premium tax credit is refundable, meaning you can receive it even if you don’t owe federal income tax.
Cost Sharing Reductions: Lowering Your Out-of-Pocket Costs
Cost sharing reductions (CSRs) are the second key form of financial assistance under the ACA, specifically designed to lower your out-of-pocket costs when you use healthcare services. These costs include deductibles, copayments, and coinsurance.

Who is Eligible for Cost Sharing Reductions?
Eligibility for CSRs is linked to both premium tax credit eligibility and income level. You are eligible for cost sharing reductions if you:
- Qualify for premium tax credits.
- Have a household income between 100% and 250% of the Federal Poverty Level (FPL).
How Cost Sharing Reductions Work
Unlike premium tax credits, which can be applied to any metal tier plan, cost sharing reductions are exclusively applied to silver plans. When eligible individuals enroll in a silver plan, CSRs are applied to significantly reduce their deductibles and other cost-sharing amounts, making the plan’s out-of-pocket costs more similar to a gold or even platinum plan.
You can still apply your premium tax credit to any metal tier plan, but to receive the benefit of reduced cost sharing, you must choose a silver-level plan. This makes silver plans particularly attractive for those who qualify for CSRs, as they become enhanced value plans offering a balance of monthly premiums and out-of-pocket expenses.
Levels of Cost Sharing Reductions
The level of cost sharing reduction you receive depends on your income:
- 100-150% FPL: These individuals receive the most generous CSRs. Silver plans are modified to have actuarial values similar to platinum plans, often referred to as CSR 94 plans (94% actuarial value). Deductibles and copays are drastically reduced. For example, in 2024, the average deductible for a standard silver plan was over $5,000, while CSR 94 silver plans had significantly lower deductibles.
- 150-200% FPL: CSRs at this income level reduce cost sharing to an 87% actuarial value (CSR 87 plans), making them similar to gold plans in terms of out-of-pocket costs. In 2024, the average deductible for CSR 87 silver plans was around $700.
- 200-250% FPL: CSRs at this level provide a more modest reduction in cost sharing, bringing the actuarial value to 73% (CSR 73 plans). While still beneficial, the reduction in deductibles and copays is less dramatic compared to the higher CSR levels. In 2024, the average deductible for CSR 73 silver plans was approximately $4,500.
It’s important to note that insurers have some flexibility in how they structure deductibles and copays within these actuarial value benchmarks. Therefore, actual deductibles and cost-sharing amounts can vary.
The ACA also sets maximum annual out-of-pocket spending limits for all Marketplace plans, with lower limits for CSR plans. In 2025, the maximum out-of-pocket limit for all plans is $9,200 (individual) and $18,400 (family), but CSR plans have even lower maximum limits, providing further financial protection.
By understanding both premium tax credits and cost sharing reductions, individuals with lower incomes can effectively utilize the Affordable Care Act’s programs to access quality, affordable health insurance through the Health Insurance Marketplace. These subsidies are crucial components of the ACA’s goal to expand health coverage and improve healthcare access for all Americans, particularly those most vulnerable to high healthcare costs.
