How this article was made: Drafted with AI assistance, then checked line by line against the primary sources listed at the end of this page (HealthCare.gov pages on cost-sharing reductions, plan categories, total costs, income and household, the federal poverty level, reporting changes, and American Indian and Alaska Native coverage, plus the federal statute at 42 U.S.C. 18071 (Cornell LII)), fetched on October 17, 2026. Worked examples use simple illustrative numbers, not real accounts. Rules, policy wording, and state laws change, so re-check the linked sources and your own documents before you act.

If you buy health insurance through the Marketplace, you may qualify for two different kinds of help. The better-known one is the premium tax credit, which lowers your monthly bill. The second is cost-sharing reductions (CSRs), which HealthCare.gov often calls "extra savings." CSRs lower what you pay when you actually use care: your deductible, your copayments and coinsurance, and your yearly out-of-pocket maximum.

There's one catch that trips people up every Open Enrollment: you only get CSRs if you pick a Silver plan. This guide explains what CSRs are, how they change a plan's numbers, how to tell whether you qualify, and how to decide between a Silver plan with extra savings and another metal level, using HealthCare.gov's pages and the federal law behind them.

What cost-sharing reductions are

The HealthCare.gov glossary defines a cost sharing reduction as a discount that lowers the amount you have to pay for deductibles, copayments, and coinsurance. "Cost sharing" is simply the part of each bill you pay yourself after your premium.

What cost-sharing reductions lower on a Silver Marketplace plan: the deductible, copayments and coinsurance, and the out-of-pocket maximum, with the monthly premium handled separately by the premium tax credit.

A few basics from HealthCare.gov's cost-sharing reductions page:

You find out when you apply. After you fill out a Marketplace application with household and income information, you learn whether you qualify for the premium tax credit and whether your income also qualifies you for extra savings.
The savings depend on income. If your income estimate falls in the range for CSRs, the amount you save depends on your specific estimate. The lower your income within the range, the more you save.
You see the exact savings only while shopping. HealthCare.gov says you'll find out exactly how much you'll save only after you apply and shop for Silver plans.
CSRs also lower your out-of-pocket maximum. The glossary notes that when you reach that maximum, your plan covers 100% of covered services for the rest of the plan year.

CSRs vs the premium tax credit

These two are easy to mix up because you apply for both at once:

The premium tax credit lowers your monthly premium. HealthCare.gov says you can use it for a plan in any metal category.
Cost-sharing reductions lower what you pay when you get care, and only on a Silver plan.

If you qualify for both and pick a Bronze or Gold plan, you keep the tax credit but give up the extra savings. That's the core trade-off this guide is about.

Why you must pick a Silver plan

Marketplace plans come in four metal categories (Bronze, Silver, Gold, and Platinum), plus Catastrophic plans for some people. HealthCare.gov's plan categories page says the categories have nothing to do with the quality of care; they're based on how you and the plan split costs.

On average, a standard Silver plan pays about 70% of covered costs and you pay about 30%. A plan's "share" is measured by actuarial value: per the glossary, a plan with a 70% actuarial value would on average leave you responsible for 30% of covered costs, though your own share could be higher or lower depending on the care you use.

CSRs work by raising a Silver plan's share. HealthCare.gov's chart lists "Silver with extra savings" as paying 73% to 96%, with you paying 6% to 27%, depending on how much savings you qualify for. Its deductible is described as generally "Low," compared with "Moderate" for a standard Silver plan.

Bar chart of the plan's share of covered costs: a standard Silver plan about 70 percent, and Silver plans with cost-sharing reductions raised to 73, 87 or 94 percent depending on household income under federal law.

What the federal law says

The rule comes from the Affordable Care Act. The statute, 42 U.S.C. § 18071, tells insurers to increase a Silver plan's share of total allowed costs for eligible enrollees to:

94% for household income from 100% to 150% of the poverty line;
87% for income above 150% and up to 200%;
73% for income above 200% and up to 250%.

The same section also provides for reduced out-of-pocket limits, coordinated with those actuarial value levels. You don't pick the reduction level yourself; HealthCare.gov says you'll see exactly how much you save when you shop for Silver plans after applying.

How much CSRs can change a plan

Percentages are abstract, so HealthCare.gov gives a concrete example. These are its illustrative numbers for one particular Silver plan, not real quotes:

HealthCare.gov example of a Silver plan with and without cost-sharing reductions: deductible 750 dollars versus 300 or 500 dollars, doctor copay 30 dollars versus 20 or 15 dollars, out-of-pocket maximum 5,000 dollars versus 3,000 dollars.

Deductible: if a Silver plan has a $750 deductible, you'd pay the first $750 for covered services (except free preventive care) before the plan pays. With CSRs, the deductible for that plan could be $300 or $500, depending on your income.
Copayments: if the plan's copay is $30 for a doctor visit, with CSRs you may pay $20 or $15 instead.
Out-of-pocket maximum: instead of $5,000, the yearly maximum for that Silver plan could be $3,000.

HealthCare.gov adds that plans in all categories have a wide range of deductibles, copays, and out-of-pocket maximums, so your own numbers will differ. The only way to see them is to apply and look at Silver plans in your area.

Why the out-of-pocket maximum matters most

For someone who rarely sees a doctor, a lower copay is nice but small. For someone who has a surgery, a hospital stay, or a chronic condition, the out-of-pocket maximum decides the worst case. HealthCare.gov's total costs page shows why: in its example, "Jane" pays her full costs until her $1,500 deductible, then 20% coinsurance, and once she reaches her $5,000 maximum, the plan pays 100% of covered services for the rest of the year. A lower maximum through CSRs shrinks that worst-case number.

Who qualifies for cost-sharing reductions

Eligibility is based on your expected household income for the year you want coverage, compared with the federal poverty level (FPL), plus the other rules for Marketplace savings. HealthCare.gov's cost-sharing page tells you to check whether your income estimate falls in the CSR range. Before November 1, HealthCare.gov's income levels page says you can estimate 2027 savings using 2026 amounts, then return on November 1 for a more accurate estimate.

The poverty-level numbers

The FPL glossary entry lists the 2026 amount for one person as $15,960 ($21,640 for a family of 2 and $33,000 for a family of 4, higher in Alaska and Hawaii). The same page notes: "Income from the previous year is used to calculate Marketplace savings for the next year."

The chart below is simple arithmetic on that one-person figure, showing where the statute's income bands fall. Treat it as an illustration, not an eligibility test; your application decides.

Illustrative arithmetic using the 2026 federal poverty level of 15,960 dollars for one person: 100 percent is 15,960 dollars, 150 percent is 23,940 dollars, 200 percent is 31,920 dollars and 250 percent is 39,900 dollars.

What counts as income

The Marketplace uses modified adjusted gross income (MAGI). HealthCare.gov's income page explains how to estimate it: start with your adjusted gross income (IRS Form 1040, line 11) and add any untaxed foreign income, non-taxable Social Security benefits, and tax-exempt interest. Don't add Supplemental Security Income. For many people, MAGI is the same as or very close to AGI.

Your household generally means the tax filer, a spouse if there is one, and tax dependents, including those who don't need coverage. Child support, gifts, and loan proceeds don't count as income; wages, self-employment income after expenses, unemployment compensation, and most IRA and 401(k) withdrawals do.

How to check whether you got CSRs

Steps to find out whether you get cost-sharing reductions: apply with a household income estimate, read your Eligibility Determination Notice, look for codes 04, 05 or 06, shop Silver plans, and compare total yearly costs.

Apply with your best income estimate. HealthCare.gov warns that a bad estimate can mean the wrong amount of savings and money owed back at tax time on the premium tax credit.
Read your Eligibility Determination Notice. HealthCare.gov says that if it states "Can choose a health plan with lower copayments, coinsurance, and deductibles" followed by (04), (05), or (06), you qualify for income-based savings, but only if you pick a Silver plan.
Filter to Silver plans when you shop, and open the plan details to see the lowered deductible and maximum.
Compare total yearly costs. Use the "Add yearly cost" option HealthCare.gov describes to estimate low, medium, or high use for each plan.
Report changes during the year. HealthCare.gov's reporting changes page says to update your application as soon as possible if your income or household changes, because it may affect the savings you're eligible for.

If you lose CSRs mid-year

If your income rises and you lose your extra savings while on a Silver plan, HealthCare.gov says you'll qualify for a Special Enrollment Period. If you want to change plans, you can then enroll in a Bronze, Silver, or Gold plan that fits your needs and budget.

Special rules for American Indians and Alaska Natives

Members of federally recognized tribes and Alaska Native Claims Settlement Act (ANCSA) Corporation shareholders get separate cost-sharing protections, and they aren't limited to Silver plans:

Zero cost sharing plan compared with limited cost sharing plan for members of federally recognized tribes and ANCSA shareholders: zero cost sharing needs income between 100 and 300 percent of poverty and income verification, limited cost sharing is available regardless of income.

A zero cost sharing plan is available if income is between 100% and 300% of the FPL and you qualify for premium tax credits. You pay no copays, deductibles, or coinsurance for care from an Indian health care provider or for essential health benefits through the plan, you don't need a referral, and it's available at any metal level. Income must be verified.
A limited cost sharing plan is available regardless of income. You pay nothing for care through an Indian health care provider, but you need a referral from an I/T/U to avoid costs for essential health benefits elsewhere. No income verification is needed.

Silver with CSRs or a different metal level?

Questions for choosing between a Silver plan with cost-sharing reductions and another metal level: does your notice show extra savings, how much care do you expect, what is each plan's total yearly cost, and do you want an HSA-eligible Bronze plan.

If your notice says you qualify, a Silver plan is often the strongest value, because you get a lower deductible and maximum that no Bronze or Gold plan will give you through the Marketplace. But it's still a comparison, not an automatic answer:

Expect little care? A Bronze plan may have a lower premium after your tax credit. HealthCare.gov notes that all Bronze and Catastrophic plans work with Health Savings Accounts. But you'd give up the extra savings, and you'd face a higher deductible if something big happens.
Expect regular care or a planned procedure? A CSR Silver plan's low deductible and maximum can save more than the premium difference. Run the yearly cost estimate.
Considering Catastrophic? HealthCare.gov says CSRs apply only to Silver plans, and Catastrophic plans also aren't eligible for the premium tax credit, no matter your income.

Two illustrative comparisons

These are illustrative scenarios using HealthCare.gov's example numbers, not quotes:

Dana expects a knee procedure next year. Her notice shows extra savings. With the example Silver plan, her maximum drops from $5,000 to $3,000. If she reaches it, that $2,000 difference likely outweighs a modest premium gap with Bronze.
Marcus is healthy and rarely uses care. He also qualifies for extra savings. He compares a Bronze plan's net premium with the Silver plan's, and adds a "low use" yearly estimate for each. If the numbers are close, the Silver plan's lower deductible is cheap protection.

Common mistakes to avoid

Picking Gold "for better coverage" when you qualify for CSRs. A Gold plan pays about 80% on average; a CSR Silver plan can pay 87% or 94% under the statute. Compare the actual premiums and plan details.
Underestimating income to get bigger savings. HealthCare.gov warns that a wrong estimate could mean paying money back on your tax credit when you file.
Ignoring the notice codes. Look for (04), (05), or (06) on your Eligibility Determination Notice.
Not reporting income changes. Changes can raise or lower your savings; reporting promptly keeps you on the right plan.
Skipping the update at Open Enrollment. HealthCare.gov says that starting November 1 you can apply for 2027 coverage or update your application with changes you expect for the year ahead; use it so your savings match next year's income.

FAQ

What are cost-sharing reductions in health insurance?

Discounts that lower your deductible, copayments, and coinsurance on a Marketplace Silver plan, plus a lower out-of-pocket maximum, per the HealthCare.gov glossary. HealthCare.gov also calls them "extra savings."

Do I have to choose a Silver plan to get cost-sharing reductions?

Yes. HealthCare.gov says you must pick a Silver plan to get extra savings. You can still use the premium tax credit on other metal levels, but you won't get CSRs. Tribal members have separate zero and limited cost sharing options.

How do I know if I qualify for cost-sharing reductions?

Check your Eligibility Determination Notice. If it says "Can choose a health plan with lower copayments, coinsurance, and deductibles" followed by (04), (05), or (06), you qualify, per HealthCare.gov.

What income qualifies for cost-sharing reductions?

It depends on your household income compared with the federal poverty level. The federal law's increased Silver plan values cover incomes from 100% up to 250% of the poverty line in three bands, per 42 U.S.C. § 18071. Your application gives the final answer.

Can I get cost-sharing reductions with a Bronze or Catastrophic plan?

No. HealthCare.gov says CSRs apply only to Silver plans, and Catastrophic plans aren't eligible for the premium tax credit either.

What happens if my income goes up and I lose cost-sharing reductions?

Report the change. If you're on a Silver plan and lose CSRs, HealthCare.gov says you qualify for a Special Enrollment Period and can switch to a Bronze, Silver, or Gold plan.

Are cost-sharing reductions the same as the premium tax credit?

No. The premium tax credit lowers your monthly premium on any metal level. CSRs lower what you pay when you get care, and only on Silver plans.

Bottom line

Cost-sharing reductions are the Marketplace savings people most often leave on the table. If your Eligibility Determination Notice shows extra savings, look hard at Silver plans: the deductible, copays, and out-of-pocket maximum can be far lower than a standard Silver plan's. Compare total yearly costs, keep your income estimate honest, and report changes during the year.
