To estimate your 2026 Indiana ACA subsidy, you compare your expected annual household income to the federal poverty level (FPL) and check where you land between the lower and upper eligibility thresholds. For 2026 coverage, most Hoosiers qualify for a premium tax credit if their household income falls between about 138% and 400% of FPL, which is roughly $21,600 to $62,600 for a single person and $44,400 to $128,600 for a family of four. Below that range you likely qualify for the Healthy Indiana Plan (Medicaid) instead, and above 400% of FPL the subsidy drops to zero because the enhanced subsidies expired at the end of 2025.
This guide breaks down the 2026 income limits, shows the numbers a subsidy calculator uses, and explains what changed for Indiana this year.
What Changed for 2026 in Indiana
The single biggest change is the return of the subsidy cliff. From 2021 through 2025, enhanced premium tax credits under the American Rescue Plan and Inflation Reduction Act removed the hard 400% FPL income cap and lowered how much everyone had to pay. Congress did not extend those enhancements, so for 2026 the rules revert to the original ACA structure.
For Indiana enrollees, that means two things. First, if your income is above 400% of FPL, you get no subsidy at all in 2026. Second, even people who still qualify pay more, because the percentage of income they are expected to contribute went back up.
The impact showed up in enrollment numbers. Indiana marketplace sign-ups for 2026 fell about 16%, one of the steeper drops in the country. The average net premium Hoosiers pay after subsidies rose from around $120 per month in 2025 to roughly $222 per month in 2026.
Indiana uses the federal marketplace at HealthCare.gov rather than running its own exchange, so the same federal rules and calculator logic apply here as in most other states.
How the Indiana ACA Subsidy Calculator Works
A premium tax credit calculator runs on a few inputs and one core formula. Here is what it needs from you:
- Household income for 2026. Use your projected modified adjusted gross income (MAGI) for the year, not last year's number.
- Household size. Count yourself, your spouse if filing jointly, and everyone you claim as a tax dependent.
- Your age and county. Premiums vary by age and by rating area within Indiana.
- Tobacco use. Insurers in Indiana can charge tobacco users more.
The calculator then finds your income as a percentage of FPL, looks up the "benchmark" plan (the second-lowest-cost Silver plan in your area), and caps what you pay for that benchmark at a set percentage of your income. The difference between the benchmark premium and your capped contribution becomes your premium tax credit. You can apply that credit to any metal-level plan, not just the Silver benchmark.
The 2026 Contribution Percentages
Under the 2026 rules, the share of income you are expected to pay for the benchmark plan rises with income. It starts at approximately 2% of income near the bottom of the eligibility range and climbs to just under 10% as you approach 400% of FPL. Once you cross 400%, the cap disappears and you pay full price.
2026 Indiana Income Limits for ACA Subsidies
The 2026 marketplace uses the 2025 federal poverty guidelines. Indiana expanded Medicaid through the Healthy Indiana Plan, so adults under 138% of FPL generally qualify for HIP rather than a marketplace subsidy. The practical subsidy range for most Hoosier households runs from 138% to 400% of FPL.
| Household size | 138% FPL (subsidy floor) | 400% FPL (subsidy cliff) |
|---|
| 1 | $21,597 | $62,600 |
| 2 | $29,187 | $84,600 |
| 3 | $36,777 | $106,600 |
| 4 | $44,367 | $128,600 |
| 5 | $51,957 | $150,600 |
| 6 | $59,547 | $172,600 |
If your income is below the 138% floor, check Healthy Indiana Plan eligibility. If your income is above the 400% figure for your household size, you will not receive a premium tax credit in 2026.
100% of FPL and the Coverage Picture
For reference, 100% of the 2025 federal poverty level is $15,650 for one person and $32,150 for a family of four. In non-expansion states, subsidies start at 100% of FPL. Because Indiana expanded Medicaid, adults below 138% are routed to HIP, which is why the effective subsidy floor here is 138% rather than 100%.
What Hoosiers Actually Pay in 2026
Numbers from Indiana's 2026 open enrollment show the real-world effect of the calculator. About 300,000 Hoosiers enrolled in individual marketplace plans, and roughly 8 in 10 qualified for a premium tax credit.
| Metric | 2026 figure |
|---|
| Share of enrollees getting a subsidy | About 80% to 85% |
| Average monthly subsidy | About $468 to $481 |
| Average net premium after subsidy | About $137 to $222 |
| Average full Silver premium, age 40 (Indianapolis) | About $490 |
| Average full Bronze premium, age 40 (Indianapolis) | About $340 |
These are averages. Your own subsidy depends on your income, age, county, and household size, which is why running your specific numbers matters more than any statewide average.
Step by Step: Estimating Your 2026 Subsidy
- Project your 2026 household income. Add up wages, self-employment income, Social Security, and other taxable income you expect this year. Use MAGI.
- Find your household size. Match it to your tax filing.
- Divide income by the FPL figure for your household size. Multiply by 100 to get your FPL percentage. For example, a single person earning $40,000 is at about 256% of the $15,650 base.
- Check the range. If you land between 138% and 400% of FPL, you likely qualify for a credit. Below 138%, check HIP. Above 400%, no credit.
- Estimate your capped contribution. Multiply your income by the applicable percentage for your FPL band (roughly 2% at the low end up to just under 10% near 400%).
- Subtract that cap from the benchmark premium. The remainder is your estimated monthly premium tax credit.

How to Enroll in an Indiana Marketplace Plan
- Go to HealthCare.gov. Indiana does not run its own exchange, so this is the official application site.
- Create or log into your account and start an application for your household.
- Enter income and household details. The system checks whether anyone qualifies for the Healthy Indiana Plan or CHIP first.
- Review your subsidy amount. HealthCare.gov calculates your advance premium tax credit automatically.
- Compare plans by metal tier. Bronze has the lowest premiums and highest out-of-pocket costs; Silver plans carry extra cost-sharing reductions if your income is under 250% of FPL; Gold has higher premiums and lower out-of-pocket costs.
- Enroll and pay your first premium to activate coverage.
Open enrollment for 2026 coverage generally runs from November 1 through mid-January. Outside that window, you need a qualifying life event such as job loss, marriage, or a new baby to enroll through a special enrollment period.

A Note on the Silver Plan Strategy
If your income is between 138% and 250% of FPL, Silver plans in Indiana come with cost-sharing reductions that lower your deductible, copays, and out-of-pocket maximum. These extra savings only apply to Silver plans. A calculator that only shows premium subsidies can understate the real value of a Silver plan for lower-income enrollees, so factor cost-sharing reductions into your decision, not just the monthly premium.
Frequently Asked Questions
What is the income limit for ACA subsidies in Indiana in 2026?
For 2026, the upper limit is 400% of the federal poverty level, which is about $62,600 for one person and $128,600 for a family of four. Because Indiana expanded Medicaid, the practical lower threshold is around 138% of FPL, since adults below that generally qualify for the Healthy Indiana Plan instead of a marketplace subsidy.
Did Indiana ACA subsidies go down for 2026?
Yes. The enhanced premium tax credits that were in place from 2021 through 2025 expired at the end of 2025, and Congress did not extend them. As a result, Hoosiers pay a higher share of their income for coverage, and the average net premium after subsidies rose from about $120 per month in 2025 to roughly $222 per month in 2026.
What is the subsidy cliff and does it affect Indiana?
The subsidy cliff is the hard income cutoff at 400% of FPL. Earn one dollar above that threshold and your premium tax credit drops to zero, with no partial credit. This cliff returned for 2026 after being suspended for several years, and it affects Indiana enrollees the same way it affects those in other federal marketplace states.
Do I qualify for the Healthy Indiana Plan instead of a subsidy?
If your household income is below 138% of FPL, you likely qualify for the Healthy Indiana Plan, Indiana's expanded Medicaid program, rather than a marketplace premium tax credit. HIP typically offers lower or no monthly premiums, so it is usually the better option when you qualify.
Where do I apply for an ACA plan in Indiana?
Indiana uses the federal marketplace, so you apply at HealthCare.gov. The site checks your eligibility for the Healthy Indiana Plan and CHIP first, then calculates your premium tax credit and shows the marketplace plans available in your county.
How is my subsidy calculated?
The marketplace caps what you pay for the benchmark plan (the second-lowest-cost Silver plan in your area) at a set percentage of your income, ranging from about 2% at the low end to just under 10% near 400% of FPL. Your subsidy is the difference between the benchmark premium and that capped amount, and you can apply it to any plan you choose.
