How coverage works
The subsidy Congress did not touch
Everyone knows the premium credits shrank. Almost nobody noticed that the other subsidy survived completely intact, and that a lot of people threw it away last year.
There are two subsidies in the Affordable Care Act. The premium tax credit reduces what you pay each month, and it was cut sharply when the enhanced version expired. The cost-sharing reduction reduces what you pay when you use care, and it was not touched at all.
What they do
A cost-sharing reduction upgrades a silver plan in place. Same premium, better plan: lower deductible, lower copays, lower coinsurance, and a much lower out-of-pocket maximum. The insurer is reimbursed for the difference, so nothing is asked of you beyond enrolling in silver.
| Income | Silver becomes | Out-of-pocket max, one person | Family |
|---|---|---|---|
| 100% to 150% of poverty | 94% value | $4,000 | $8,000 |
| 150% to 200% of poverty | 87% value | $4,000 | $8,000 |
| 200% to 250% of poverty | 73% value | $9,600 | $19,200 |
| Above 250% | ~70% value | $12,000 | $24,000 |
Read that table again. At the top tier a silver plan reaches 94% actuarial value, which is better than platinum, and the out-of-pocket maximum falls from $12,000 to $4,000. You pay the silver premium for it.
In dollars, for 2027
Using the poverty guidelines that govern 2027 coverage, the eligible range runs from $15,960 to $39,900 for one person, and from $33,000 to $82,500 for a family of four.
| Household | 100% | 150% | 200% | 250% (cut-off) |
|---|---|---|---|---|
| 1 person | $15,960 | $23,940 | $31,920 | $39,900 |
| 2 people | $21,640 | $32,460 | $43,280 | $54,100 |
| 3 people | $27,320 | $40,980 | $54,640 | $68,300 |
| 4 people | $33,000 | $49,500 | $66,000 | $82,500 |
Two things that make them unusually valuable now
- They are never reconciled. Unlike advance premium tax credits, there is no true-up at tax time, no Form 8962 equivalent, and no repayment. Given that premium credit repayment caps were eliminated starting in 2026, a subsidy with no clawback risk is worth more than it used to be.
- They survived intact. The 2025 reconciliation law reinstated appropriated funding for cost-sharing reductions, conditioned on excluding abortion coverage. The eligibility rules themselves were untouched.
How to make sure you get them
- Estimate your income accurately on the application. Estimating too high can push you out of the range entirely.
- Enroll in a silver plan. Not bronze. Not gold.
- Compare the actual deductible and out-of-pocket maximum on the silver plans available to you. The upgrade should be visible in the plan summary; if it is not, something is wrong with the application.
- If your income changes during the year and crosses 250%, report it. Crossing the line is a qualifying event for cost-sharing purposes.
- Run the numbers first in the calculator, which tells you which tier you land in.
Common questions
Were cost-sharing reductions affected when the enhanced credits expired?
No. Cost-sharing reduction eligibility and generosity are unchanged. They remain available between 100% and 250% of the federal poverty level, on silver plans only. That makes them the most valuable subsidy still fully intact.
Do I have to repay cost-sharing reductions at tax time?
No. Unlike advance premium tax credits, cost-sharing reductions are never reconciled on your tax return. There is no Form 8962 equivalent and no clawback, which matters a great deal now that premium credit repayment caps have been eliminated.
Why do they only work on silver plans?
The statute attaches them to silver. Enroll in bronze, gold, or platinum and you get nothing, even if your income qualifies. This is the single most common way people leave money on the table in this market.
How much are they actually worth?
Substantial. At the top tier the out-of-pocket maximum falls to $4,000 for one person in 2027, against $12,000 on a standard plan. Deductibles and copays fall in proportion. A 94% silver plan provides better protection than most platinum plans sold.
