One Dollar Over This Line Costs a Family $14,469

Most things in the tax code phase out. You earn a bit more, you get a bit less, the change is gradual and roughly fair.

The health insurance subsidy cliff does not work that way. One side of the line, the government pays a large share of your premium. One dollar past it, the government pays nothing. There is no taper, no partial credit, no gradual reduction. It stops.

For 2026 coverage that line sits at 400% of the federal poverty level: $62,600 for a single-person household, $128,600 for a household of four, using the 2025 HHS guidelines.

What Crossing It Actually Costs

Using CMS filed rates for 2026, here is the median lowest-cost Silver plan for a household of two 40-year-olds and two children, and what the credit was worth at the top of the eligible range:

• Texas — $27,278 a year full price. Credit at the cliff: about $14,469.
• North Carolina — $26,303. Credit: about $13,495.
• Florida — $25,674. Credit: about $12,865.
• Oklahoma — $22,455. Credit: about $9,646.

That is the amount that disappears when household income goes from $128,600 to $128,601. To be better off after crossing the cliff in Texas, that household needs to earn roughly $14,500 more — pre-tax — just to stand still.

For a single filer the numbers are smaller but the mechanism is identical: about $2,296 in Texas, $1,992 in North Carolina, $1,795 in Florida.

Why This Is Worse Than It Used to Be

From 2021 through 2025, enhanced subsidies capped what anyone paid at 8.5% of income with no upper income limit. The cliff was, in effect, switched off.

Those enhanced credits expired on December 31, 2025. The cliff came back for 2026, and a large number of households that had never encountered it before walked straight into it — many without realising until the first premium came out.

At the same time, insurers filed a median 15% increase for 2027 across all 50 states and DC, on top of roughly 20% finalised increases for 2026. The credit that used to absorb those increases no longer exists above the line, so above-cliff households absorb the full amount themselves, two years running.

Who Walks Into This

Rarely wealthy people. It is overwhelmingly self-employed households in the band just above the line — a contractor with a good year, a practice owner, a consultant, a two-income household where one spouse got a raise. People who do not feel rich and who get no help at all.

It also catches people who are not near the line in November and are past it by December. Commission income, a distribution, a capital gain, a spouse’s bonus. Because credits are advanced monthly and reconciled at tax time, crossing the line late in the year means repaying the entire advance credit — the repayment caps that protect lower-income households do not apply above 400% FPL.

What You Can Actually Do About It

Lower the number that counts. Eligibility runs on modified adjusted gross income, and for the self-employed several things reduce it: the self-employed health insurance deduction, a SEP-IRA or solo 401(k) contribution, an HSA contribution, and ordinary business expenses. If you are a few thousand over, this is often winnable — and worth modelling before December rather than discovering in April.

Check the household size figure, not the single one. The cliff scales with household size. A great many people assume $62,600 applies to them when their actual line is far higher.

Stop assuming the marketplace is cheapest. Below the cliff it usually is, because the credit is doing the work. Above the cliff there is no credit, and unsubsidised marketplace coverage is competing on its own merits against medically underwritten plans, which are priced on health rather than income. Those are not sold on the exchange, so shopping healthcare.gov cannot show them to you.

Underwritten coverage is not right for everyone and is not offered in every state. If your health history would not clear underwriting, the marketplace’s guaranteed-issue protection is worth more than any price difference. But if you are above the cliff and in good health, running only one of the two comparisons is how people overpay for years.

Premiums are CMS Plan Year 2026 QHP Landscape filed rates — full price before any premium tax credit, not a quote or an offer of coverage. Poverty guidelines are HHS 2025, which govern 2026 coverage. Medically underwritten coverage is not available in every state and acceptance depends on health history; nothing here is an offer. Verify all figures at enrollment.
