Cost-sharing reduction

A cost-sharing reduction lowers what you pay when you actually use care: the deductible, the copays, the coinsurance and the out-of-pocket maximum. It is separate from the premium tax credit, which lowers the monthly bill.

The rule that catches people is that it only attaches to silver plans. Take the same subsidy to a bronze plan for a lower premium and the cost-sharing reduction does not come with you. It disappears.

That produces the single most common bad decision in marketplace shopping. Someone eligible for a strong cost-sharing reduction sorts by premium, picks bronze, saves a modest amount every month, and then meets a deductible several times larger than the silver one would have been the first time they need care.

The reduction is scaled by income, and the lower the income, the larger it is. At the strongest tier a silver plan can end up with cost sharing better than gold, at a silver price.

In New York: there is a step before any of this, and it makes the whole question moot for a large number of people.

Below 200% of the federal poverty level, the relevant program is usually the Essential Plan, not a subsidised marketplace plan. The Essential Plan has a $0 premium, no deductible, and no enrollment season. Comparing silver plans without knowing that is how people end up paying a deductible they did not need to have. The 2026 income limits by household size.

Above that line, the practical instruction is short: if you are eligible for a cost-sharing reduction, sort silver plans, not all plans. The marketplace will tell you whether you qualify when you enter income and household size.

And note what changed underneath: the enhanced premium tax credits expired December 31, 2025, so the premium side of this comparison is harsher than it was, which makes the cost-sharing side matter more rather than less.
