Subsidies in Tennessee for 2027: Premium Tax Credits and Cost-Sharing Reductions

The single most important thing to know about 2027: the enhanced premium tax credits expired on December 31, 2025, and Congress has not extended them. For 2027, the original pre-2021 ACA rules are back — premium tax credits are generally available to households earning 100% to 400% of the federal poverty level (FPL), with a hard cliff at 400%: one dollar over the line means zero credit. Cost-sharing reductions are available at 100%–250% FPL, but only if you pick a Silver plan.

Who qualifies for premium tax credits in 2027

Premium tax credits (PTCs) lower your monthly premium on a marketplace plan. Under the pre-2021 rules now in force:

• Income band: roughly 100%–400% of the federal poverty level.
• The 400% cliff is real. Under the expired enhanced rules there was no income cap; now, earning one dollar over 400% of FPL wipes out the entire credit.
• Below 100% FPL: generally no credits. In Tennessee — which has not expanded Medicaid — this is the coverage gap: too much income for TennCare in most cases, too little for marketplace subsidies.

Income bands in dollars, based on the confirmed 2026 HHS poverty guidelines ($15,960 for a single person / $33,000 for a family of four):

So a single Tennessean earning roughly $15,960–$63,840, or a family of four earning roughly $33,000–$132,000, is in the credit-eligible band. Note: the 2027 HHS poverty guidelines arrive in January 2027, and the bands above may shift slightly when they're published.

Cost-sharing reductions: lower deductibles, copays, and out-of-pocket max

Cost-sharing reductions (CSRs) are the second discount, and they cut what you pay when you get care — your deductible, copays, coinsurance, and out-of-pocket maximum. Two conditions, both required:

1. Household income of 100%–250% FPL.
2. You enroll in a Silver plan.

If you're in the CSR income band, a Silver plan usually beats Bronze — the reductions are applied automatically to the plan, and they're worth real money over a year of care. (If you're above 250% FPL, Silver carries no CSR advantage over other tiers.)

Advance credits vs. tax time: how the money actually flows

You have two choices for premium tax credits:

• Take them in advance (APTC). The credit goes straight to your insurer each month and lowers the premium you pay. Most enrollees do this — 87% of marketplace shoppers took advance credits during 2026 open enrollment.
• Claim them at tax time. Pay the full premium all year, then claim the credit on your tax return.

If you take credits in advance, the marketplace settles up with you at tax time based on your actual income for the year. Earned more than you estimated? You'll likely owe some of the credit back. Earned less? You may get more. That's why reporting income changes to HealthCare.gov as soon as they happen — a raise, a job loss, a new household member — is the single best way to avoid a surprise on your tax return.

One caution: the details of how excess advance credits get repaid (including repayment limits) have been reported as changing for tax years after 2025, and we couldn't fully verify the current rule against a primary source before this page was written. Treat repayment as a real risk if your income rises mid-year, and confirm the current rules at HealthCare.gov or with a tax preparer.

Also note: the marketplace checks the income you report against federal data and sends data-matching notices when they don't line up. Answer them by the deadline, and keep your application current.

What the expiration has already done

The return of the pre-2021 rules is already visible in the numbers:

• During 2026 open enrollment, 23.1 million people selected marketplace plans — down about 1.2 million (5%) from 2025.
• The share getting advance premium tax credits fell from 92% to 87%.
• The average post-credit monthly premium rose to $178 from $113 in 2025 — a 58% increase.
• Insurer-filing analyses estimate roughly 3 million people have dropped marketplace coverage since the enhanced credits expired.

We're watching this: could Congress change the 2027 rules?

Status, not a prediction. In January 2026, the House passed a three-year extension of the enhanced premium tax credits (H.R. 1834) — but the Senate had not taken it up as of October 2026. A separate Senate extension bill (S. 3385) failed to get the 60 votes needed in December 2025, and a bipartisan compromise was still being negotiated with no floor vote scheduled. Unless Congress acts, the pre-2021 structure described on this page governs 2027 coverage. If the Senate passes it and it becomes law, the subsidy math on this page changes — and we'll update this page the same week. Check 2027 Open Enrollment before November 1, 2026, for the latest.

Close to the 400% cliff? An HSA can help

HSA contributions lower your modified adjusted gross income. If you're just over 400% of the poverty level, pairing a bronze plan with HSA contributions can bring you back into the tax credit range. How it works, with an example

Your next step

1. Estimate your credit on HealthCare.gov — window shopping shows your post-credit premium for your actual age, county, and income.
2. Learn how the credit interacts with the rest of your costs on What Health Insurance Actually Costs, and how the marketplace itself works on The Marketplace.
3. If your income is near a boundary (100%, 250%, or 400% of FPL), report changes promptly and read the tax-time guidance above.

Frequently asked questions

What exactly is the 400% "cliff"?

Under the current rules, premium tax credits stop entirely at 400% of the federal poverty level. There's no phase-out — a household at 399% of FPL can get a credit, and a household at 401% gets nothing. For a family of four in 2027, that line sits around $132,000 a year.

I'm below 100% of the poverty level. Can I get a subsidy?

Generally, no — premium tax credits start at 100% of FPL. Because Tennessee hasn't expanded Medicaid, most childless adults below 100% FPL fall into the coverage gap: no TennCare and no marketplace subsidies. Parents and caretaker relatives may qualify for TennCare up to 100% FPL — see TennCare.

Do I have to take the tax credit every month, or can I wait until tax time?

Your choice. Most people take it in advance so their monthly premium is lower, but you can pay full price all year and claim the whole credit on your tax return. Taking it at tax time avoids any risk of having to pay credit money back.

What happens if my income goes up in the middle of the year?

Report it to HealthCare.gov right away. Your advance credit will be recalculated, which protects you from owing a large amount at tax time. If you don't report it, the difference gets settled on your tax return — and you may owe.

Do cost-sharing reductions work on any plan, or just Silver?

Just Silver. CSRs only apply to Silver-tier marketplace plans. If your income is 100%–250% of FPL, compare Silver plans first — a Bronze plan won't carry the reductions no matter your income.

Could the enhanced credits come back for 2027?

Only if Congress acts. The House passed a three-year extension (H.R. 1834) in January 2026, but the Senate hasn't taken it up as of October 2026. See the "We're watching this" note above — we'll update this page the week anything changes.
