The One Big Beautiful Bill Act (OBBBA) recalibrates how ACA premium tax credits work starting with 2026 coverage. The biggest changes: the temporary elimination of the 400% federal poverty level income cap is gone, meaning households earning above 400% FPL lose all premium tax credit eligibility again. Repayment caps on excess advance payments are also gone, so anyone who received too much credit during the year now owes back the full difference, not a capped amount. The Marketplace also requires stricter income verification and ends automatic re-enrollment and continuous special enrollment periods tied to income alone. Together, these changes mean higher premiums for many enrollees and a higher chance of an unexpected tax bill at filing time.
What Actually Changed: The Short Version
For 2021 through 2025, the American Rescue Plan Act and the Inflation Reduction Act temporarily removed the 400% FPL income cliff and capped how much excess advance premium tax credit (APTC) a household had to repay if their income came in higher than estimated. Those temporary rules expired at the end of 2025 and were not extended in the One Big Beautiful Bill Act. Congress did not create new ACA subsidy provisions in OBBBA to replace them. Instead, the law lets the enhanced subsidy structure lapse and layers on new verification and enrollment restrictions.
Practically, this means the 2026 plan year reverts closer to the pre-2021 ACA subsidy rules, with a few new twists specific to OBBBA.
The 400% FPL Cliff Is Back
Before 2021, anyone with household income above 400% of the federal poverty level received no premium tax credit at all, no matter how high their premium was relative to income. The enhanced subsidy years removed that hard cutoff entirely. Starting with 2026 coverage, the cliff returns. If your household income lands even one dollar above 400% FPL, you are not eligible for any premium tax credit.
2026 approximate 400% FPL income thresholds (48 contiguous states):
| Household Size | 100% FPL (approx.) | 400% FPL Cutoff (approx.) |
|---|
| 1 | $15,650 | $62,600 |
| 2 | $21,150 | $84,600 |
| 3 | $26,650 | $106,600 |
| 4 | $32,150 | $128,600 |
| 5 | $37,650 | $150,600 |
Add roughly $5,500 per additional household member to estimate the 100% FPL line, and roughly $22,000 per additional member for the 400% line. Alaska and Hawaii use higher poverty guidelines, so households there should check the current HHS guidelines rather than use these mainland figures.
Applicable Percentage Table for 2026
Even for households under 400% FPL, the applicable percentage of income used to calculate the premium tax credit reverts to the pre-enhanced schedule. This determines what share of income you are expected to pay toward the benchmark (second-lowest-cost Silver) plan before the credit covers the rest.
| Income as % of FPL | Applicable % of Income (2026) |
|---|
| Under 133% | 2.10% |
| 133% to 150% | 3.14% to 4.19% |
| 150% to 200% | 4.19% to 6.60% |
| 200% to 250% | 6.60% to 8.44% |
| 250% to 300% | 8.44% to 9.96% |
| 300% to 400% | 9.96% flat |
Compared to the enhanced subsidy years, when the lowest-income enrollees paid 0% to 2% of income and the highest earners near 400% FPL paid around 8.5%, the 2026 schedule asks for a larger share of income at every tier, and cuts off entirely above 400% FPL.
Repayment Caps Are Gone
This is the change with the sharpest financial teeth. During the enhanced subsidy years, if your actual income came in higher than what you estimated when you enrolled, and you received more advance premium tax credit than you were entitled to, the amount you had to repay at tax time was capped based on your income level. Lower-income households had smaller repayment caps; the cap disappeared only above 400% FPL.
For tax years beginning after December 31, 2025, that cap is eliminated for everyone. If your advance premium tax credit exceeded your actual premium tax credit for the year, whether because you took a raise, picked up freelance income, or simply guessed too low, you now owe back the full excess amount when you file Form 8962 with your tax return. There is no ceiling protecting lower-income households from a large repayment.
This makes accurate income estimates far more important than in prior years. Enrollees with variable income, self-employment income, or seasonal work face real exposure to a surprise tax bill.
Tax Filing and Reconciliation Requirement
OBBBA also ties future premium tax credit eligibility to past tax compliance. Beginning with the 2026 plan year, if HHS notifies the Marketplace that an enrollee failed to file a tax return and reconcile advance premium tax credits from a prior year using Form 8962, that person becomes ineligible for premium tax credits going forward until the filing is corrected. In practice, skipping a required reconciliation can cut off a household's subsidy the following year, not just create a repayment bill.
Special Enrollment Period Restrictions
The continuous special enrollment period that allowed people with income at or below 150% FPL to enroll in Marketplace coverage at any point during the year, not just during open enrollment or after a qualifying life event, is eliminated. Starting in 2026, enrolling outside open enrollment based on income alone, without a qualifying life event such as job loss, marriage, birth of a child, or loss of other coverage, no longer makes someone eligible for a premium tax credit. This closes a pathway that many lower-income enrollees previously used to get covered mid-year.
Automatic re-enrollment procedures are also being tightened, and the Marketplace is applying more rigorous income and eligibility verification checks before approving or renewing advance premium tax credits, which can slow down enrollment and require more documentation than in past years.
What This Means for Your Household
If your income is comfortably under 400% FPL and stable, you should still qualify for a premium tax credit in 2026, though it will likely cover a smaller share of your premium than it did in 2024 or 2025. If your income hovers near or above 400% FPL, expect to lose subsidy eligibility altogether once your final income is reconciled, even if you received advance payments during the year assuming otherwise.
The safest practice for 2026 is to estimate income conservatively (leaning toward your realistic higher-end projection, not your lowest), update your Marketplace account promptly whenever income changes during the year, and file taxes on time every year, since a missed reconciliation can now block next year's credit entirely.
How to Apply or Update Your Marketplace Coverage
- Log in or create an account at HealthCare.gov, or your state-based Marketplace if your state runs its own exchange.
- Report your current household income as accurately as possible, including any expected raises, bonus income, or self-employment earnings for the full plan year.
- Compare plans using the total premium after any tax credit is applied, not just the sticker price, and pay attention to the benchmark Silver plan used to calculate your credit.
- Choose how much advance credit to take. You can elect to take less than the full estimated credit in advance to reduce the risk of owing money back at tax time.
- Update your application immediately if your income, household size, or job situation changes during the year.
- File Form 8962 with your federal tax return every year you receive advance premium tax credit, to reconcile the estimated credit against your actual income.
Frequently Asked Questions
Does the 400% FPL income cliff apply to everyone in 2026?
Yes. Starting with 2026 coverage, anyone with household income above 400% of the federal poverty level is ineligible for any premium tax credit, regardless of how much they spend on premiums relative to income. This restores the rule that applied before 2021.
What happens if I underestimate my income for 2026 and end up earning more?
You will likely have to repay some or all of the advance premium tax credit you received beyond what your actual income qualifies for. Unlike 2021 through 2025, there is no cap limiting how much you must repay. The full excess amount is due when you file your tax return.
Can I still get covered mid-year if my income drops below 150% FPL?
You can still enroll during open enrollment or after a qualifying life event like losing other coverage, marriage, or having a baby. However, the continuous special enrollment period based purely on low income, without a qualifying life event, is no longer available starting in 2026.
Will I lose my premium tax credit if I forget to file taxes one year?
You risk it. Beginning with the 2026 plan year, failing to file a return and reconcile prior-year advance premium tax credits on Form 8962 can make you ineligible for premium tax credits going forward until the issue is resolved.
Are the 2026 applicable percentages higher than in recent years?
Yes. The applicable percentage of income used to calculate premium tax credits reverts to the pre-enhanced schedule, which is generally higher at every income tier than the temporary 2021 to 2025 percentages, meaning enrollees are expected to pay a larger share of income toward the benchmark plan before the credit kicks in.
Where can I check if I still qualify for a premium tax credit under the new rules?
Start with a free eligibility screening that checks your household income against current program limits, including ACA premium tax credits and other assistance programs you may qualify for based on your state and situation.
