Quick answer: For 2026 coverage, ACA premium tax credits end completely at 400% of the federal poverty level: $62,600 for a single person, $84,600 for a two-person household, and $128,600 for a family of four. Earn one dollar over the line and the credit drops to zero. Households just above the cutoff pay the full unsubsidized premium, while a household earning slightly less gets help with the same plan. If you’re near or above the line, it’s worth comparing a marketplace quote against a private plan quote before you renew.
Who this is for
- Arizona households earning near or slightly above the 400% FPL line
- Self-employed people and 1099 contractors whose income swings year to year
- Families who saw their 2026 marketplace premium jump when the enhanced subsidies expired
- Early retirees and anyone over 50 who is priced out of the unsubsidized marketplace
- Anyone who got a repayment surprise on their 2025 taxes and wants to avoid it in 2026
The problem: the cliff is back, and it’s a cliff, not a slope
The enhanced ACA subsidies that ran from 2021 through 2025 capped what anyone paid for a benchmark Silver plan at 8.5% of income, no matter how much they earned. Those enhancements expired at the end of 2025. For 2026, the original ACA rule is back: premium tax credits are only available to households between 100% and 400% of the federal poverty level.
That 400% line is not a phase-out. Below it, you get help. One dollar above it, you get nothing, and if you received advance credits during the year and your final income lands over the line, you repay every dollar when you file.
The people this hurts most aren’t high earners. They’re the households sitting just over the threshold, who pay the same full premium as someone earning three times as much.
2026 subsidy cliff income limits (continental U.S.)
| Household size | 400% FPL for 2026 coverage |
|---|---|
| 1 | $62,600 |
| 2 | $84,600 |
| 3 | $106,600 |
| 4 | $128,600 |
These figures use the 2025 poverty guidelines, which is what 2026 coverage runs on. The line moves every year, so a household that qualified in 2025 may not in 2026, and vice versa.
Why the cliff hits families and older applicants hardest
Unsubsidized marketplace premiums are set by age, household size, and location, not by income. That means:
- A family of four just over $128,600 pays the full premium for every member. A neighbor earning a few thousand less gets a credit against the same plan.
- Older applicants pay more. Marketplace rates rise with age, so a 58-year-old couple just over $84,600 faces a much larger unsubsidized bill than a 30-year-old couple at the same income.
- Income is hard to predict. Self-employed households don’t know their final number until year-end, which is exactly when it’s too late to change plans.
Marketplace vs. private plans: how the math changes above the cliff
Private (medically underwritten) plans price coverage based on health rather than income. For a healthy household above the subsidy line, that can mean a lower premium than the full unsubsidized marketplace rate. It is not the right fit for everyone, so here’s the honest comparison.
| ACA marketplace plan | Private underwritten plan | |
|---|---|---|
| Premium based on | Age, location, tobacco use | Age, location, and health history |
| Subsidy available | Yes, if under 400% FPL | No |
| Health questions | None; guaranteed issue | Yes; approval isn’t guaranteed |
| Pre-existing conditions | Covered | May be excluded or declined |
| Enrollment window | Open enrollment or a qualifying life event | Any time of year |
| HSA-eligible | Yes, if you pick an HSA-qualified high-deductible plan | No |
| Best fit | Under the subsidy line, or anyone with ongoing health conditions | Healthy households above the subsidy line |
Two things to weigh carefully: private plans are not HSA-eligible, and underwriting is evaluated per person. One family member with a significant health history can change the answer for the whole household.
Real-world scenarios
Scenario 1: Self-employed couple in Scottsdale, income around $90,000. They’re about $5,000 over the two-person line, so no marketplace credit. Both are healthy and under 50. A private plan quote is worth running alongside the marketplace quote, since the private premium may land well under the full marketplace rate. They should also confirm with their tax preparer whether a deductible retirement or HSA contribution (on an eligible plan) could bring their MAGI under the line, which would make the marketplace the better deal.
Scenario 2: Family of four, income around $125,000, one child with asthma. They’re under the four-person limit, so they qualify for a premium tax credit, and the child’s condition is fully covered on any marketplace plan. This household should stay on the marketplace. A private plan would cost them the subsidy and could exclude or rate up the child’s coverage. The right move is to pick the best marketplace plan and keep a close eye on income so they don’t accidentally cross $128,600.
Scenario 3: Single early retiree, age 61, income around $70,000 from investments. Over the single-person limit, and age-rated marketplace premiums at 61 are steep. If she’s healthy, a private plan can bridge the gap until Medicare at 65. If she has ongoing conditions, the marketplace is still the safer option, and it’s worth reviewing whether adjusting withdrawals could bring her income under $62,600 for the year.
What to do this week
- Estimate your 2026 MAGI honestly. Include every household member’s income, not just the primary earner’s.
- Find your household’s 400% line in the table above and note how far above or below it you are.
- If you’re within a few thousand dollars of the line, talk to your tax preparer about whether deductible contributions could move you under it. The subsidy is often worth more than the tax savings alone.
- If you’re clearly above the line, request both a marketplace quote and a private plan quote for the same household so you’re comparing real numbers.
- Account for every family member’s health history before assuming a private plan will approve everyone.
- Put this on the calendar for next fall. Income and the threshold both change every year; 2027 coverage will use a higher poverty guideline ($63,840 for a single person).
Frequently asked questions
What is the ACA subsidy cliff? It’s the income point, 400% of the federal poverty level, where premium tax credits stop completely. Unlike a tax bracket, there’s no gradual reduction. One dollar over the line means no subsidy at all.
What are the 2026 ACA subsidy income limits in Arizona? For 2026 coverage: $62,600 for one person, $84,600 for two, $106,600 for three, and $128,600 for four. Arizona uses the continental U.S. figures.
Did the ACA subsidy cliff come back in 2026? Yes. The enhanced subsidies from 2021 through 2025 removed the cliff temporarily. They expired December 31, 2025, and the original 400% cutoff applies again for 2026 coverage.
What happens if my income goes over the limit during the year? If you received advance premium tax credits and your final income for the year is above 400% FPL, you have to repay the full amount when you file your 2026 taxes.
Is a private health plan cheaper than the marketplace if I’m over the subsidy limit? It can be, especially for healthy households and older applicants, because private plans price on health rather than age alone. It depends on the health history of everyone being covered, so the only way to know is to compare quotes.
Can I get a private plan if I have a pre-existing condition? Private plans are medically underwritten, so a condition may be excluded, rated up, or lead to a decline. Marketplace plans cover pre-existing conditions with no health questions, which is why they remain the better choice for many households.
Are private health plans HSA-eligible? No. If contributing to an HSA is important to you, that’s a point in favor of an HSA-qualified marketplace plan.
Can I switch to a private plan outside of open enrollment? Yes. Private plans can be started any month of the year. Marketplace plans require open enrollment or a qualifying life event such as job loss, marriage, a move, or a new baby.
