The starting point for the subsidy calculation is also the end point for reconciling the subsidy on the California 540 income tax return. First, your Modified Adjusted Gross Income (MAGI) is converted into a percentage of the federal poverty level (FPL), which varies by household size. That FPL percentage is then matched to the Applicable Figure. The Applicable Figure is itself a percentage, the percentage of the household’s fair share or consumer responsibility for health insurance. It is a sliding scale with income closer to the FPL being responsible for less of the health insurance premium.
