Tennessee residents shopping for health insurance in 2026 face a changed landscape. The enhanced premium tax credits that reduced costs for millions of Americans from 2021 through 2025 expired on December 31, 2025. The "subsidy cliff" has returned, and premiums in Tennessee are rising an average of 30% for 2026. Understanding exactly where you fall in the income brackets determines whether you qualify for subsidized coverage, TennCare, or fall into the coverage gap with no affordable options.
What the ACA Marketplace Offers in Tennessee
Tennessee uses the federally facilitated marketplace, so residents apply through HealthCare.gov rather than a state-run exchange. The marketplace offers four metal tiers: Bronze, Silver, Gold, and Platinum. Premium tax credits help lower your monthly premium costs, and cost-sharing reductions (CSRs) are available on Silver plans for households below 250% of the federal poverty level (FPL).
Tennessee has not expanded Medicaid under the ACA and remains a non-expansion state in 2026. That means TennCare (Tennessee Medicaid) covers a narrower population than in expansion states, and ACA marketplace subsidies play a larger role for low-to-moderate income Tennesseans.
2026 ACA Income Limits for Tennessee
ACA subsidies for 2026 plans are based on the 2025 federal poverty guidelines. Eligibility runs from 100% FPL at the bottom to 400% FPL at the top. Earning even one dollar above 400% FPL means losing all premium tax credits in 2026.
ACA Subsidy Income Limits by Household Size
| Household Size | 100% FPL (minimum) | 150% FPL | 200% FPL | 250% FPL | 300% FPL | 400% FPL (maximum) |
|---|
| 1 person | $15,060 | $22,590 | $30,120 | $37,650 | $45,180 | $60,240 |
| 2 people | $20,440 | $30,660 | $40,880 | $51,100 | $61,320 | $81,760 |
| 3 people | $25,820 | $38,730 | $51,640 | $64,550 | $77,460 | $103,280 |
| 4 people | $31,200 | $46,800 | $62,400 | $78,000 | $93,600 | $124,800 |
| 5 people | $36,580 | $54,870 | $73,160 | $91,450 | $109,740 | $146,320 |
| 6 people | $41,960 | $62,940 | $83,920 | $104,900 | $125,880 | $167,840 |
The 150% to 250% FPL range is especially important for Silver plan enrollees, as cost-sharing reductions (CSRs) are available only in that band, lowering your deductible and out-of-pocket costs significantly.
What Changed in 2026
From 2021 to 2025, the American Rescue Plan Act and Inflation Reduction Act provided enhanced subsidies that eliminated the 400% FPL cliff and capped premiums at a fixed percentage of income for all enrollees. Those provisions expired at the end of 2025. Starting with 2026 plans:
- The 400% FPL cliff is back. Income above $60,240 for one person means no subsidy.
- Households above 400% FPL pay full unsubsidized premiums.
- Premium percentages that households must contribute have increased back to pre-2021 levels.
- Average Tennessee marketplace premiums rose approximately 30% for 2026 before subsidies.
TennCare vs. Marketplace: Who Qualifies for What
Because Tennessee has not expanded Medicaid, there is a gap between TennCare eligibility and marketplace subsidy eligibility for certain adults. Here is how the thresholds stack up:
| Program | Adults Without Dependents | Parents of Minor Children | Pregnant Women | Children |
|---|
| TennCare (Medicaid) | Not eligible | Up to 105% FPL | Up to 195% FPL | Up to 250% FPL |
| CHIP (CoverKids) | N/A | N/A | N/A | Up to 250% FPL |
| ACA Marketplace Subsidies | From 100% FPL | Above 105% FPL | Not typically eligible (TennCare covers) | Not typically eligible (CHIP covers) |
Tennessee increased the parent income limit to 105% FPL in mid-2024, which is the highest income limit for parents among all non-expansion states.
The Tennessee Coverage Gap
Adults in Tennessee who earn below 100% FPL but are not eligible for TennCare fall into what is called the "coverage gap." This affects an estimated 82,000 Tennessee residents. These individuals earn too little to qualify for marketplace subsidies (which require income of at least 100% FPL) and do not qualify for TennCare because Tennessee did not expand Medicaid.
Who is most at risk:
- Childless adults under 65 with income below $15,060 per year
- Parents with income below 105% FPL ($15,813 for a single parent)
If you are in the coverage gap, options are limited. You can check whether you qualify for TennCare based on disability, age (65+), or other special circumstances. Community health centers (federally qualified health centers) offer sliding-scale fees regardless of insurance status.
How Subsidies Work in 2026
The premium tax credit is calculated as the difference between the benchmark plan cost (the second-lowest-cost Silver plan in your area) and the maximum you are expected to contribute based on your income. In 2026, the expected contribution percentages have reverted to pre-ARP levels:
| Income Level | Expected Premium Contribution (% of income) |
|---|
| 100% to 133% FPL | 2.06% of income |
| 133% to 150% FPL | 3.09% to 4.12% of income |
| 150% to 200% FPL | 4.12% to 6.18% of income |
| 200% to 250% FPL | 6.18% to 8.25% of income |
| 250% to 300% FPL | 8.25% to 9.78% of income |
| 300% to 400% FPL | 9.78% of income |
| Above 400% FPL | No subsidy |
If the benchmark plan in your Tennessee county costs less than your expected contribution, the tax credit is $0 even if your income is within the eligible range.
Cost-Sharing Reductions for Silver Plans
Tennesseans who enroll in a Silver plan and have income between 100% and 250% FPL qualify for cost-sharing reductions (CSRs) in addition to the premium tax credit. CSRs reduce your deductible, copays, and out-of-pocket maximum. You must select a Silver plan specifically to receive CSRs; the reduction does not apply to Bronze, Gold, or Platinum plans.
| Income Range | Actuarial Value with CSR |
|---|
| 100% to 150% FPL | 94% |
| 150% to 200% FPL | 87% |
| 200% to 250% FPL | 73% |
| Above 250% FPL | 70% (standard Silver) |
At 94% actuarial value, the plan covers roughly 94% of average medical costs, making it comparable to a Platinum plan at a Silver plan premium price.
How to Apply for Marketplace Coverage in Tennessee
Tennessee uses HealthCare.gov for all marketplace applications. Open enrollment for 2026 coverage closed in January 2026, but you may still qualify if you have a Special Enrollment Period (SEP).
Qualifying Events for a Special Enrollment Period
- Loss of job-based health insurance
- Marriage or divorce
- Birth or adoption of a child
- Moving to a new ZIP code or county
- Gaining lawful immigration status
- Losing eligibility for Medicaid or CHIP
- Income change that affects your subsidy amount
Step-by-Step Application Process
Step 1: Gather your documents. You will need Social Security numbers for all household members, income information (pay stubs, tax returns, or self-employment records), information about any employer-sponsored coverage available to you, and current health insurance information if applicable.
Step 2: Create or log in to your HealthCare.gov account. Go to healthcare.gov and click "Get Coverage." Create an account with your email address or log in if you already have one.
Step 3: Start a new application. Select your state (Tennessee), confirm your address, and enter household information including all members who need coverage.
Step 4: Enter income information. Report your expected household income for the full coverage year. Include wages, self-employment income, Social Security benefits, and other taxable income. Do not include child support received or Supplemental Security Income (SSI).
Step 5: Review your eligibility results. HealthCare.gov will show whether you qualify for premium tax credits, cost-sharing reductions, TennCare, or CoverKids (CHIP). If you qualify for TennCare, you will be transferred to TennCare Connect to complete that application.
Step 6: Compare plans. Review Bronze, Silver, Gold, and Platinum options in your area. If your income is between 100% and 250% FPL, consider Silver plans to access cost-sharing reductions.
Step 7: Enroll and pay your first premium. After selecting a plan, you must pay your first month's premium by the deadline to activate coverage. Coverage typically begins the first of the month following enrollment.
Applying for TennCare
If HealthCare.gov determines you may be eligible for TennCare rather than marketplace coverage, you can apply directly through TennCare Connect at tenncare.com. Tennessee residents can also apply by phone at 1-800-342-3145 or in person at a local Department of Human Services (DHS) office.
TennCare Connect allows you to submit documents, check your application status, report changes, and renew coverage online.
Tennessee Marketplace Enrollment Numbers
Nearly 643,000 Tennesseans enrolled in ACA marketplace plans in 2025, more than double the 2020 enrollment figure before the enhanced subsidies took effect. With the expiration of enhanced tax credits, health policy analysts project that 142,000 to 203,000 Tennesseans could drop coverage due to higher costs in 2026.
If you were enrolled in a 2025 marketplace plan and have not updated your enrollment for 2026, your plan may have auto-renewed at significantly higher costs.
