Subsidies for insurance bought through health benefit exchanges
Premium tax credits that pay part of the cost of individual-market health coverage.
JCT line: "Subsidies for insurance purchased through health benefit exchanges". Falls to $81.5B by FY2029 as the temporarily enhanced subsidies lapse.
Income-tested and phased out with income, so the credit is structurally directed toward lower- and middle-income households buying their own coverage. Concentration on the beneficiary side is low; the meaningful concentration is on the receiving side, among insurers.
Structural reading
The fourth-largest item in the code and the mirror image of the employer health exclusion, which makes the pair worth reading together: both subsidise health coverage, one through employment and one outside it, and they are scored separately because they sit in different parts of the statute rather than because they do different things. The structural point specific to this one is that the money is paid to the insurer rather than the household. That makes the enrollee the nominal beneficiary and the carrier the reliable one, and it means the subsidy supports the premium level itself, a concentrated benefit that survives regardless of how broadly the coverage spreads.
Who gets it
The channels the benefit actually flows through, described by asset position, entity form and form of return. Never by named individuals.
Cost split by the concentration score. That score is a judgement rather than a published figure, so treat this as the scale of the split, not an audited allocation.
- Households without access to employer coverage
Eligibility requires buying on the individual market, which makes this the counterpart to the employer exclusion for people outside employment-based coverage.
- Participating insurers
The credit is paid to the insurer on the enrollee's behalf, so it is a guaranteed revenue stream to carriers in the individual market and supports premium levels that would otherwise be unsustainable.
Who pays
General taxpayers.
This transfer follows a general pattern, asymmetric organisation, sustained expert attention, and scheduled expiry dates.
