Cost-Sharing Reductions (CSR): The Silver Plan Savings Most Shoppers Miss in 2027

Updated October 2026 for the 2027 plan year

What are cost-sharing reductions?

CSRs are a second Marketplace subsidy that lowers what you pay when you get care, not what you pay each month. HealthCare.gov calls them “extra savings” and defines them as a discount that lowers your deductibles, copayments and coinsurance (HealthCare.gov glossary).

The Affordable Care Act created two kinds of help. The premium tax credit lowers your monthly premium on any metal level. CSRs lower your deductible, copays, coinsurance and out-of-pocket maximum, but only on Silver. If you qualify for both, you can get both on the same plan.

When you qualify, the insurer doesn’t sell you a different plan. It gives you a Silver plan variation: the same plan, network and drug list, with lower cost sharing built in. That is why CSRs are often called the best deal on the Marketplace. You pay a Silver premium and can get coverage that pays a share of costs closer to Gold or Platinum.

Who qualifies for cost-sharing reductions in 2027?

You qualify for CSRs in 2027 if your expected 2027 household income is between 100% and 250% of the federal poverty level, you qualify for the premium tax credit, and you enroll in a Silver plan through HealthCare.gov or your state’s Marketplace (45 CFR 155.305(g)).

Income limits for 2027 coverage use the 2026 HHS poverty guidelines. The table shows the three CSR bands for the 48 contiguous states and DC. Alaska and Hawaii use higher guidelines.

Three rules decide whether you actually get CSRs:

• You must qualify for the premium tax credit. An affordable offer of job-based coverage, or eligibility for Medicaid or Medicare, generally rules you out.
• Medicaid comes first at the low end. In states that expanded Medicaid, most adults under 138% FPL get Medicaid instead. In states that didn’t expand, Marketplace help starts at 100% FPL. Check Medicaid eligibility.
• Household income is your 2027 estimate. It uses the same modified adjusted gross income as the premium tax credit. Full charts are in our federal poverty level guide.

Mixed families follow a special rule. If people on one policy fall into different CSR categories, the whole policy gets the category everyone qualifies for (45 CFR 155.305(g)(3)). Sometimes enrolling family members on separate policies keeps the stronger savings, so ask before you enroll.

How much do cost-sharing reductions save?

CSRs save more the lower your income. At 100% to 150% FPL a Silver plan pays about 94% of covered costs on average, more than a standard Platinum plan. At 150% to 200% it pays about 87%, and at 200% to 250% about 73%, compared with 70% for standard Silver.

That percentage is the plan’s actuarial value: the share of total covered costs the plan pays for an average group of enrollees. HealthCare.gov lists Silver with extra savings as paying 73% to 96% (HealthCare.gov).

Sources: 45 CFR 156.420 and CMS 2027 payment parameters. The out-of-pocket maximums are legal caps; many plans set lower ones.

In practice, insurers reach these levels with lower deductibles, lower copays and a lower out-of-pocket maximum. The exact mix differs by plan, so compare the Summary of Benefits and Coverage for each Silver option. Our guide to comparing health insurance plans shows how.

Why do you have to pick a Silver plan?

You have to pick a Silver plan because federal rules allow CSRs only on Silver plans bought through the Marketplace. HealthCare.gov says you must pick a Silver plan to get the extra savings; on Bronze, Gold or Platinum you can still use the premium tax credit, but not CSRs.

The rule is in 45 CFR 155.305(g): CSRs go to an enrollee “enrolled through the Exchange in a silver-level QHP” (eCFR). The only exception is for American Indians and Alaska Natives, covered below.

Two practical points follow:

• Buy on-exchange. A Silver plan bought directly from an insurer, outside the Marketplace, has no CSRs and no tax credit. A licensed agent can enroll you through the Marketplace so the savings apply.
• Choosing Bronze gives up CSRs. A Bronze plan may have a lower premium after the tax credit, but its deductible and out-of-pocket maximum stay at full Bronze levels.

What is silver loading?

Silver loading is the practice of raising Silver plan premiums to cover the cost of CSRs after the federal government stopped paying insurers for them in 2017. Because the premium tax credit is tied to a Silver plan, silver loading also makes tax credits larger.

Insurers must still give CSRs to everyone who qualifies, even though the federal government doesn’t reimburse them. Most build that cost into Silver premiums only, because Silver is the only tier with CSRs (KFF). CMS’s 2026 payment rule codified silver loading where the state regulator permits it, and a 2025 House proposal to fund CSR payments was ruled out of order under Senate budget rules (KFF).

What it means for you in 2027:

• Bigger tax credits. Your premium tax credit is based on the second-lowest-cost Silver plan in your area. When Silver premiums are loaded, the credit grows.
• Cheaper Bronze and Gold after the credit. The larger credit can be applied to any metal level, so some Gold plans can cost about the same as, or less than, Silver after the credit.
• Silver without CSRs can be poor value. If your income is above 250% FPL, you pay a loaded Silver premium without the extra savings. Compare Gold and Bronze carefully.

Silver loading varies by state and insurer. It is one more reason to shop every year instead of auto-renewing: KFF found insurers proposed a median 15% premium increase for 2027 (KFF). Our 2027 subsidy guide explains the tax credit math.

When does a CSR Silver plan beat Bronze or Gold?

A CSR Silver plan usually beats Bronze and Gold at incomes up to 200% FPL, because it pays 87% to 94% of costs with an out-of-pocket maximum of $4,000 or less for one person. From 200% to 250% FPL the gap narrows, so compare total yearly cost before choosing.

Think about the worst case. A Bronze plan’s out-of-pocket maximum can reach the $12,000 legal cap for one person in 2027. At 150% FPL that would be a large share of yearly income, while the CSR Silver cap is $4,000 or less. If you have a chronic condition, regular prescriptions or a planned procedure, the CSR Silver plan is almost always the safer choice.

Cost-sharing reductions for American Indians and Alaska Natives

Members of federally recognized tribes and Alaska Native Claims Settlement Act (ANCSA) Corporation shareholders get stronger protections. With income from 100% to 300% FPL, they can enroll in a zero cost-sharing plan with no deductibles, copays or coinsurance (HealthCare.gov).

• Any metal level. Federal rules apply zero cost-sharing variations to plans at any level of coverage, not just Silver (45 CFR 156.420).
• Any income, Indian health care providers. Care from the Indian Health Service, a tribe, a tribal organization or an urban Indian organization, or through a referral, has no cost sharing on any Marketplace plan.
• Enroll any month. Tribal members and ANCSA shareholders can enroll in or change Marketplace plans once a month, with coverage starting the first day of the next month.

How do you get cost-sharing reductions?

You get CSRs by applying through HealthCare.gov or your state’s Marketplace, entering an accurate 2027 income estimate, and choosing a Silver plan. If you qualify, the Silver plans you see already show the lower deductibles and copays.

1. Estimate your 2027 household income. Use pay stubs, 1099s and last year’s tax return. Our self-employed guide helps with variable income.
2. Apply through the Marketplace. Use HealthCare.gov, your state exchange or a licensed agent who enrolls you on-exchange.
3. Check your eligibility results. The results say whether you qualify for the premium tax credit and for extra savings.
4. Choose a Silver plan. Compare deductibles, out-of-pocket maximums, networks and drug lists across Silver plans.
5. Enroll by the deadline. Enroll by December 15, 2026 for coverage on January 1, 2027, and pay your first premium.
6. Report income changes. Update your application as soon as income or household changes during 2027.

Open Enrollment for 2027 coverage on HealthCare.gov runs November 1, 2026 to January 15, 2027; state exchanges may run longer. A qualifying life event can open a Special Enrollment Period. See all dates in our Open Enrollment 2027 guide.

Do you have to pay back cost-sharing reductions?

No. CSRs are not reconciled at tax time, so you don’t repay them if your income ends up higher than you estimated (KFF). The premium tax credit is different.

Advance premium tax credits are reconciled on IRS Form 8962. Starting with tax year 2026, the old repayment caps no longer apply, so any excess credit must be paid back in full (IRS). An honest income estimate protects your tax refund and keeps your CSR level correct. See Form 1095-A for how reconciliation works.
