ACA Subsidy (Premium Tax Credit)
A government credit that lowers marketplace health insurance premiums based on your income.
The ACA premium tax credit is a subsidy that reduces what you pay for health insurance bought through the marketplace, scaled to your income relative to the federal poverty level. The lower your modified adjusted gross income, the larger the credit — which gives early retirees who control their taxable income real leverage over their premiums.
The rules around subsidies have been in flux: enhanced credits that expanded eligibility expired at the end of 2025, and the hard 'subsidy cliff' at 400% of the federal poverty level returned for 2026, with legislation pending. Because the specifics change, the durable point is the mechanism — manage MAGI, manage your premium — while the exact thresholds should be confirmed at HealthCare.gov each year.
This definition is general information to help you understand a term, not financial, tax, or legal advice. Figures that change year to year (limits, thresholds, rates) should be confirmed against current official sources. For guidance on your situation, a licensed fee-only fiduciary is the right next step.
