A health insurance subsidy is federal financial help that reduces what you pay for a Marketplace plan, either by lowering your monthly premium or by shrinking your deductibles and copays when you use care. For 2026, you generally qualify if your household income falls between 100% and 400% of the Federal Poverty Level, you’re a U.S. citizen or lawfully present immigrant, and you don’t have access to affordable coverage through an employer or a program like Medicare or Medicaid. You apply by shopping for a plan on HealthCare.gov or your state’s exchange during open enrollment.
The Two Kinds of Subsidies
The premium tax credit is the main subsidy and the one most enrollees receive. It lowers your monthly premium, and you can take it in advance so your bill drops immediately, or claim it on your tax return. The credit is available with any metal tier — Bronze, Silver, Gold, or Platinum — and its legal authority sits in Section 36B of the Internal Revenue Code.1Office of the Law Revision Counsel. 26 USC 36B – Refundable Credit for Coverage Under a Qualified Health Plan
Cost-sharing reductions are the second kind. Instead of lowering your premium, they lower what you pay when you actually get care. You only get them if you enroll in a Silver-tier plan.2HealthCare.gov. Cost-Sharing Reductions Pick Bronze or Gold and you keep your premium tax credit, but the cost-sharing help disappears. The strength of the reduction depends on income: at up to 150% FPL, a Silver plan covers about 94% of average medical costs; from 151% to 200% FPL, about 87%; and from 201% to 250% FPL, about 73%. The individual out-of-pocket maximum sits around $3,500 in the two lower bands and rises to roughly $8,450 in the top band.
Every Marketplace plan, subsidized or not, must cover ten categories of essential health benefits including emergency care, hospitalization, maternity care, mental health treatment, and prescription drugs.3Centers for Medicare & Medicaid Services. Information on Essential Health Benefits (EHB) Benchmark Plans Insurers cannot charge more or deny coverage because of a pre-existing condition.
Who Qualifies
Income
Household income must fall between 100% and 400% of the Federal Poverty Level for your family size.4Internal Revenue Service. Eligibility for the Premium Tax Credit For 2026, in the 48 contiguous states, that means:5Department of Health and Human Services. 2026 Poverty Guidelines
- Single person: $15,960 to $63,840
- Family of two: $21,640 to $86,560
- Family of three: $27,320 to $109,280
- Family of four: $33,000 to $132,000
The Marketplace uses Modified Adjusted Gross Income (MAGI), which includes wages, self-employment income, Social Security benefits, and investment returns. It does not include non-taxable benefits like Supplemental Security Income.6Internal Revenue Service. Modified Adjusted Gross Income In states that expanded Medicaid, people below 138% of the FPL are generally covered by Medicaid instead of Marketplace subsidies.7HealthCare.gov. Medicaid Expansion and What It Means for You
Residency and Immigration Status
You must be a U.S. citizen or lawfully present immigrant. Lawful presence covers a wide range of categories including permanent residents, refugees, asylees, people with Temporary Protected Status, and holders of valid non-immigrant visas.8HealthCare.gov. Health Coverage for Lawfully Present Immigrants DACA recipients are not eligible for Marketplace coverage.9HealthCare.gov. Immigration Status to Qualify for the Marketplace
Employer Coverage
If your employer offers health insurance that is both affordable and meets minimum value standards, you generally cannot get Marketplace subsidies. For 2026, employer coverage counts as affordable if your share of the self-only premium is 9.96% or less of household income.10Internal Revenue Service. Minimum Value and Affordability A plan meets minimum value if it covers at least 60% of average medical costs.
One important exception: the affordability test for family members is based on the cost of covering the whole family, not the employee alone. Before a 2022 rule change often called the “family glitch” fix, families could be locked out of subsidies whenever the employee’s self-only premium was affordable, even if adding the family cost thousands more. That fix is still in effect, so family members can qualify for Marketplace subsidies on their own when employer family coverage is too expensive.
How the Subsidy Amount Is Calculated
The government decides how much you’re expected to contribute toward coverage based on your income, then pays the difference between that amount and the cost of a benchmark plan in your area.11Internal Revenue Service. Questions and Answers on the Premium Tax Credit The benchmark plan is the second-lowest-cost Silver plan available to you. You don’t have to enroll in that plan; the credit is simply pegged to its price.
Your expected contribution is your household income multiplied by an “applicable percentage” that the IRS publishes each year. For 2026, those percentages run from 2.10% of income for the lowest earners up to 9.96% for people near the top of the eligibility range, sliding within each band.12Internal Revenue Service. Revenue Procedure 2025-25
A simplified example: a single person earning about $31,920 (200% of FPL) has an applicable percentage of 6.60%. That works out to about $2,107 per year, or $176 a month, as their share. If the second-lowest-cost Silver plan in their area is $600 a month, the premium tax credit is $424 a month. They can apply that credit to any Marketplace plan; a Bronze plan would leave a very low monthly bill, and a Gold plan would still cost more but with the credit applied.
What Changed for 2026
The enhanced premium tax credits that Congress created in 2021 and extended through 2025 expired at the end of December 2025. This is the biggest shift in Marketplace affordability since the ACA launched.
From 2021 through 2025, no household paid more than 8.5% of income toward the benchmark Silver plan, and people earning above 400% FPL could still receive credits. Neither of those provisions survived into 2026. The 400% FPL cap is back, so a household earning even a dollar over that line gets zero assistance.4Internal Revenue Service. Eligibility for the Premium Tax Credit The applicable percentage now tops out at 9.96% instead of 8.5%, so households near the upper end of eligibility pay more than they did last year.12Internal Revenue Service. Revenue Procedure 2025-25
The other big change hits at tax time. Repayment of excess advance credits used to be capped based on income, so lower-income households owed back only a few hundred dollars at most if they had received too much. Starting with plan year 2026, those caps are gone. You owe back every dollar of excess advance credit, regardless of income.13CMS Agent and Broker FAQ. Are There Limits to How Much Excess Advance Payments of the Premium Tax Credit Consumers Must Pay Back Accurate income reporting matters more than ever.
How to Apply
You apply by shopping for a plan on the Health Insurance Marketplace during open enrollment, which runs November 1 through January 15.14HealthCare.gov. When Can You Get Health Insurance Enroll by December 15 and coverage starts January 1; enroll between December 16 and January 15 and coverage starts February 1.
You can apply at HealthCare.gov, at your state’s exchange if it runs its own, by phone, or through an approved broker or insurer platform. The eligibility determination runs through the same federal system either way. During the application, you’ll provide household details and estimate your income for the coverage year. The system generates a subsidy estimate and shows you plan options with adjusted premiums. Compare carefully. A Bronze plan with a large credit can look almost free monthly but leaves you with high deductibles, while a Silver plan opens the door to cost-sharing reductions that pay off when you actually need care. You’ll need to pay your first month’s premium to activate coverage.
Outside open enrollment, you can enroll or switch during a Special Enrollment Period triggered by a qualifying life event: marriage, a birth, losing other coverage, or moving.15HealthCare.gov. Getting Health Coverage Outside Open Enrollment Most events give you 60 days; losing Medicaid or CHIP gives you 90 days.
Reporting Income Accurately
The Marketplace doesn’t take your word for your income. It cross-checks what you report against IRS and Social Security Administration records. Acceptable documentation includes tax returns, W-2s, 1099 statements, and pay stubs. Freelancers with variable income may need to provide profit-and-loss statements.
When your reported income doesn’t match government records, the Marketplace flags a data-matching issue and sets a deadline to resolve it. Most issues carry a 90-day deadline from your eligibility notice; income discrepancies get an automatic extension to 150 days total; citizenship and immigration issues have a 95-day deadline, and missing that one terminates your coverage.16Centers for Medicare & Medicaid Services. Locating Information About and Resolving Data Matching Issues These deadlines are enforced.
Household changes matter too. Income from every tax-household member who files a return counts toward your MAGI, so a spouse’s new job or an adult child moving out and filing independently can shift your subsidy amount. Report income and household changes to the Marketplace as they happen; that keeps your advance credits close to what you actually qualify for and shrinks any gap at tax time.
Reconciling at Tax Time
If you received advance premium tax credits during the year, you must file Form 8962 with your federal return to reconcile the advance payments against the credit your final income actually supports.17Internal Revenue Service. About Form 8962, Premium Tax Credit This is not optional. Skip it and the IRS can hold up future refunds and block advance credits for the following year.
Two outcomes are possible. If your actual income was higher than estimated, you received too much and owe the difference back. If your income was lower, you get an additional credit as part of your refund.18Internal Revenue Service. Instructions for Form 8962
With the repayment caps gone for plan year 2026, the stakes for overestimating your credit are higher. If your advance credits exceeded your entitlement by $3,000, you owe all $3,000 back. People with unpredictable income — gig workers, commission earners, anyone with a side business — should think about deliberately claiming less credit in advance and taking the rest at tax time. Higher monthly premiums, no April surprise.
Situations That Trip People Up
Self-Employed Workers
Self-employed workers are fully eligible for premium tax credits and the Marketplace is often their best route. The wrinkle is that they can also deduct health insurance premiums on their tax return, and the two benefits interact in a circle: the deduction lowers MAGI, which raises the credit, which reduces the deductible premium. IRS Publication 974 lays out an iterative calculation that usually yields the best result and a simplified version that’s easier.19Internal Revenue Service. Publication 974, Premium Tax Credit Using these worksheets is technically optional, but skipping them usually means leaving money on the table.
When estimating income on the application, self-employed filers subtract allowable business expenses before arriving at MAGI. Standard Schedule 1 deductions, including the self-employed health insurance deduction, student loan interest, and deductible IRA contributions, also reduce the income figure the Marketplace uses.
Medicare
Once you become eligible for premium-free Medicare Part A, you lose eligibility for Marketplace financial assistance. For most people that’s the first day of the month they turn 65. Marketplace coverage does not end on its own; you have to cancel it, and any advance credits received after you became Medicare-eligible must be repaid.20Centers for Medicare & Medicaid Services. Transitioning from Marketplace to Medicare Coverage If you’re eligible for Part A but would have to pay a premium for it (because you don’t have enough work credits), you keep Marketplace subsidy eligibility until you actually enroll in Part A.
COBRA
COBRA lets you keep employer coverage after leaving a job, but you pay the full premium without an employer contribution, so it’s expensive. You can drop COBRA and enroll in a subsidized Marketplace plan, but the 60-day Special Enrollment Period runs from when you first lost your employer coverage, not when you decide COBRA is too costly.21Centers for Medicare & Medicaid Services. COBRA Coverage and the Marketplace Miss that window and you’ll have to wait for open enrollment. Being eligible for COBRA but not enrolled in it doesn’t block Marketplace subsidies.
Appealing a Marketplace Decision
If the Marketplace denies your subsidy or approves less than you expected, you can appeal within 90 days of the eligibility notice.22Centers for Medicare & Medicaid Services. Appealing Eligibility Decisions in the Health Insurance Marketplace Appeals can be filed online through your HealthCare.gov account, by mail, or by fax. The process begins with an informal review; if that doesn’t settle it, you can request a formal hearing by phone with a federal hearing officer, and a written decision typically arrives within 90 days.23Centers for Medicare & Medicaid Services. Marketplace Eligibility Appeals Process Overview Appeals are worth pursuing when you have documentation the Marketplace didn’t see — a corrected tax return, proof of a life event, or evidence your income was reported incorrectly.
