The Affordable Care Act offers two separate types of financial assistance for people who buy health insurance through the Marketplace: the premium tax credit (PTC) and cost-sharing reductions (CSRs). These are often confused, but they work in completely different ways. One lowers your monthly premium. The other lowers what you pay when you actually use medical care. You may qualify for both, one, or neither, depending on your income and the plan you choose.
If you're shopping for coverage on HealthCare.gov or a state marketplace, understanding how these two subsidies interact could save you thousands of dollars per year. This guide breaks down exactly how each works, who qualifies, and what changed in 2026.
What Is the Premium Tax Credit?
The premium tax credit (PTC) is a subsidy that reduces your monthly health insurance premium. Instead of paying the full cost of a Marketplace plan, the government pays part of it on your behalf. You can receive the credit in advance (called an Advance Premium Tax Credit, or APTC), applied directly to your monthly bills, or claim it when you file your federal taxes.
The credit amount depends on your household income relative to the Federal Poverty Level (FPL) and the cost of the benchmark plan in your area. The benchmark is the second-lowest-cost Silver plan available to you.
For 2026, the premium tax credit is available to households earning between 100% and 400% of the FPL. This is a significant change from 2024 and 2025, when enhanced credits temporarily removed the 400% income cap. Those enhanced credits expired at the end of 2025, and the strict income ceiling returned.
2026 Premium Tax Credit Income Limits
| Household Size | 100% FPL | 200% FPL | 300% FPL | 400% FPL (cutoff) |
|---|
| 1 person | $15,650 | $31,300 | $46,950 | $62,600 |
| 2 people | $21,150 | $42,300 | $63,450 | $84,600 |
| 3 people | $26,650 | $53,300 | $79,950 | $106,600 |
| 4 people | $32,150 | $64,300 | $96,450 | $128,600 |
If your Modified Adjusted Gross Income (MAGI) exceeds 400% FPL by even one dollar, you receive zero premium tax credit in 2026. This "subsidy cliff" is back after being suspended during the pandemic-era enhanced credit years.
How the Credit Amount Is Calculated
The PTC ensures you do not pay more than a set percentage of your income toward the benchmark Silver plan premium. In 2026, those percentages range from approximately 2.1% of income at 100% FPL up to 9.96% of income at 300 to 400% FPL. The credit covers the gap between that capped amount and the actual benchmark premium cost.
For example, if the benchmark Silver plan in your area costs $600 per month and your income cap is $100 per month (based on FPL percentage), the credit covers the remaining $500. You can apply this credit toward any metal tier plan, not just Silver.
What Are Cost-Sharing Reductions?
Cost-sharing reductions are a separate subsidy that lowers what you pay out of pocket when you use medical services. This includes your deductible, copays, coinsurance, and annual out-of-pocket maximum. CSRs do not reduce your monthly premium directly.
To receive cost-sharing reductions, two things must be true:
- Your household income must be between 100% and 250% of the Federal Poverty Level.
- You must enroll in a Silver plan through the Marketplace.
That second requirement is critical. If you are eligible for CSRs but choose a Bronze, Gold, or Platinum plan, you forfeit the cost-sharing benefit entirely. The only way to receive CSRs is through a Silver plan.
How CSRs Work in Practice
Silver plans normally have an actuarial value of about 70%, meaning the plan covers roughly 70% of covered medical costs on average. CSRs boost that actuarial value significantly:
| Income Range | Actuarial Value with CSR | Comparable Metal Level |
|---|
| 100% to 150% FPL | 94% | Better than Platinum |
| 150% to 200% FPL | 87% | Close to Platinum |
| 200% to 250% FPL | 73% | Better than standard Silver |
| Above 250% FPL | 70% (no CSR) | Standard Silver |
At the highest CSR tier (100 to 150% FPL), your out-of-pocket maximum drops to $3,500 for an individual and $7,000 for a family. At the middle tier (200 to 250% FPL), those limits are $8,450 and $16,900 respectively.
2026 CSR Income Limits
| Household Size | 100% FPL | 150% FPL | 200% FPL | 250% FPL (cutoff) |
|---|
| 1 person | $15,650 | $23,475 | $31,300 | $39,125 |
| 2 people | $21,150 | $31,725 | $42,300 | $52,875 |
| 3 people | $26,650 | $39,975 | $53,300 | $66,625 |
| 4 people | $32,150 | $48,225 | $64,300 | $80,375 |
Premium Tax Credit vs Cost-Sharing Reductions: Side-by-Side Comparison
| Feature | Premium Tax Credit (PTC) | Cost-Sharing Reduction (CSR) |
|---|
| What it reduces | Monthly premium | Deductibles, copays, out-of-pocket max |
| Income range | 100% to 400% FPL | 100% to 250% FPL |
| Plan requirement | Any metal tier (Bronze, Silver, Gold, Platinum) | Silver plans only |
| How applied | Monthly credit or annual tax credit | Automatically built into eligible Silver plans |
| Can you get both? | Yes, if income is 100 to 250% FPL | Yes, if also eligible for PTC |
| What if income changes? | Credit adjusts at tax filing | Eligibility determined at enrollment |
Can You Get Both?
Yes. If your household income falls between 100% and 250% of the FPL, you are likely eligible for both the premium tax credit and cost-sharing reductions. This is the "sweet spot" of ACA assistance.
In this income range, the best strategy is almost always to enroll in a Silver plan. The CSR-enhanced Silver plan will have dramatically lower out-of-pocket costs compared to standard Silver, and you still get the premium tax credit to reduce your monthly payment. A CSR-enhanced Silver plan at 100 to 150% FPL can outperform even Platinum plans on total cost for most users.
If your income is above 250% FPL but below 400% FPL, you can still get the premium tax credit but you will not receive cost-sharing reductions. In that range, you have more flexibility to choose a Bronze, Gold, or Platinum plan based on your expected healthcare use.
The 2026 Enhanced Credit Expiration: What Changed
Through 2025, Congress had temporarily expanded the premium tax credit through the American Rescue Plan and the Inflation Reduction Act. Those enhancements did two things:
- Removed the 400% FPL income cap entirely, allowing higher earners to qualify.
- Increased credit amounts across all income levels, reducing premiums further.
Both enhancements expired on January 1, 2026. The practical effects are significant:
- Households above 400% FPL no longer qualify for any premium tax credit.
- Households at all income levels will generally see higher net premiums.
- On average, Marketplace premiums are estimated to increase by over $1,000 per year for current enrollees after the enhanced credits expired.
- There is no longer a cap on subsidy repayment at tax time. If you received too much in advance credits and your income ends up higher than estimated, you must repay the full difference.
If your income is near the 400% FPL threshold, this change is especially important. In 2025, you received some credit even above that line. In 2026, crossing it means losing the entire credit.
How to Apply for Both Subsidies
Both the premium tax credit and cost-sharing reductions are accessed through the same application process on the Marketplace. You do not apply for them separately.
Step-by-Step Application Process
- Create an account at HealthCare.gov (federal marketplace) or your state's exchange if you live in a state that runs its own.
- Complete the Marketplace application. You will enter household size, income, and basic personal information. The application uses your estimated annual income to determine eligibility.
- Get your eligibility results. The system automatically calculates whether you qualify for the premium tax credit, cost-sharing reductions, or Medicaid.
- Compare plans. If you qualify for CSRs, the tool will show you enhanced Silver plans with lower out-of-pocket costs. The cost-sharing benefit is automatically applied to eligible Silver plans.
- Select a plan and enroll. If you choose to receive the premium tax credit in advance, it is applied to your monthly premium starting with your first month of coverage.
- Report income changes. If your income changes during the year, update your Marketplace application promptly. This prevents a large repayment or underpayment at tax filing time.
- Reconcile at tax time. Use IRS Form 8962 to reconcile your advance premium tax credits with your actual annual income. Any difference is either refunded or owed.
When Can You Enroll?
The annual Open Enrollment Period for 2026 coverage ran from November 1 through January 15 in most states. If you missed it, you may still be eligible to enroll through a Special Enrollment Period if you had a qualifying life event such as job loss, marriage, divorce, a new baby, or losing other coverage.

Common Mistakes to Avoid
Choosing a Bronze plan when you qualify for CSRs. If your income is under 250% FPL, the enhanced Silver plan almost always beats a Bronze plan on total costs. Bronze has lower premiums but much higher deductibles. With CSRs, the Silver plan can have a deductible as low as a few hundred dollars.
Underestimating income on the application. Receiving too much in advance credits leads to a repayment at tax time. In 2026, there is no cap on that repayment, so an income miscalculation can result in a large unexpected tax bill.
Overestimating income to avoid repayment. This can cause you to receive a smaller credit throughout the year than you are entitled to. You will get the difference back at tax filing, but you will have been overpaying premiums monthly.
Not updating the Marketplace when income changes. If you get a raise, change jobs, or have other income shifts mid-year, update your application. This keeps your advance credits accurate and avoids surprises in April.
Assuming CSRs are automatic without choosing Silver. The cost-sharing reduction benefit only applies if you actively enroll in a Silver plan. It is not transferable to other plan types.
Medicaid vs. Premium Tax Credit
If your income is below 138% FPL and you live in a state that expanded Medicaid, you will likely be directed to Medicaid rather than Marketplace coverage. Medicaid is free or nearly free and has no premiums for most enrollees.
In the 10 states that have not expanded Medicaid, adults with incomes below 100% FPL fall into a coverage gap. They earn too little for Marketplace subsidies (which start at 100% FPL) and do not qualify for traditional Medicaid in non-expansion states. This gap affects millions of low-income adults.
If you are near the Medicaid threshold, it is worth checking your state's specific rules before assuming you need Marketplace coverage.
Frequently Asked Questions
What is the difference between a premium tax credit and a cost-sharing reduction?
A premium tax credit lowers your monthly health insurance premium. A cost-sharing reduction lowers what you pay at the doctor or hospital, including your deductible, copays, and out-of-pocket maximum. They are separate subsidies with different income requirements, though you can qualify for both if your income is between 100% and 250% of the FPL.
Do I have to choose a Silver plan to get cost-sharing reductions?
Yes. Cost-sharing reductions are only available on Silver plans purchased through the Marketplace. If you qualify for CSRs but enroll in a Bronze, Gold, or Platinum plan, you lose the cost-sharing benefit entirely. You can still get a premium tax credit with other plan types, but not CSRs.
Can I get both a premium tax credit and a cost-sharing reduction?
Yes, if your income is between 100% and 250% of the Federal Poverty Level, you qualify for both. This combination is generally the most financially valuable option in the Marketplace and often makes a Silver plan the best choice even if the premium appears higher than Bronze.
What happened to the enhanced premium tax credits in 2026?
The enhanced premium tax credits that existed from 2021 through 2025 expired at the end of 2025. Starting in 2026, the income cap returned at 400% of the FPL, and credit amounts decreased for all income levels. Households above 400% FPL no longer qualify for any premium tax credit.
What is 400% of the federal poverty level in 2026?
For a single person, 400% FPL in 2026 is approximately $62,600. For a family of four, it is approximately $128,600. These are the income cutoffs above which no premium tax credit is available in 2026.
How do I apply for premium tax credits and cost-sharing reductions?
Both are applied for through the same application at HealthCare.gov or your state's Marketplace. You enter your household size and estimated annual income, and the system automatically determines what assistance you qualify for. You do not file separate applications for the PTC and CSR.
What happens if I receive too much advance premium tax credit?
You must reconcile advance premium tax credits against your actual income when you file your federal taxes using Form 8962. If you received more in advance than you were entitled to, you owe the difference back to the IRS. Starting in 2026, there is no repayment cap, meaning you are responsible for the full overpayment amount.
Are cost-sharing reductions available outside the Marketplace?
No. Cost-sharing reductions are only available through Marketplace plans. Off-exchange coverage, even from the same insurance company, does not include CSR benefits. This is another reason why enrolling through the official Marketplace matters.
Can I get premium tax credits if I have employer insurance?
Generally no. If you have access to affordable employer-sponsored coverage that meets minimum value requirements, you are not eligible for premium tax credits. An employer plan is considered affordable if the employee-only premium costs less than 9.02% of your household income in 2026.
Where can I check my eligibility?
You can use the free screener at BenefitsUSA to estimate whether you qualify for Marketplace subsidies, Medicaid, or other assistance programs based on your household income and size.
